Corporate Finance Dissertation Topics: Researchable Ideas on Financing, Payout, M&A and Listing Decisions

Strong corporate finance dissertation topics start with a decision a firm actually makes: how to fund a project, whether to return cash, whether to bid for a rival or whether to list. The best ones also name a rule, event or dataset that lets you observe what happened next. This list is built that way, so each topic points to a specific mechanism you can test with public evidence.

Questions to Settle Before You Choose a Corporate Finance Dissertation Topic

Before you commit to a title, check it against these questions.

• Which firm decision am I testing: funding, payout, investment, a takeover or a listing?
• Is there a rule change, deal or announcement that gives me a clean before and after, or will I rely on differences between firms?
• Can I get accounts, deal announcements or listing documents for enough firms and years without a paid database?
• Do I want an event study, a panel regression, a case study or interviews with finance directors?
• Is this really corporate finance, or is my idea about asset prices, banks or household money?

That last question matters because the field is wide. The topics below cover firm-level decisions on financing, payout, capital budgeting, takeovers, listings, distress and disclosure. Portfolio construction and return prediction fit better under investment and asset-pricing topics, while questions about banks as lenders belong in banking and finance research ideas.

Position correct as of October 2026. Several topics rely on rules that are new, under consultation or still bedding in, including Provision 29 of the UK Corporate Governance Code (financial years beginning on or after 1 January 2026), the FCA’s UK Sustainability Reporting Standards rules and the Takeover Panel’s consultation PCP 2026/1. Check each regulator’s own pages for the current position before you build a design around any of them.

Most topics name UK or US rules because those carry the verifiable detail, but the designs transfer. If you study elsewhere, swap in your own country’s interest limitation rule, takeover code or listing regime instead of treating it as a separate topic. Check your university’s rules on ethics approval, referencing and marking before you finalise a title, and try the dissertation topic finder if you want a second route into this list.

Capital Structure and Debt Financing Dissertation Topics

Capital structure research asks why firms mix debt and equity as they do, and recent tax rules now supply several sharp tests. Day-to-day treasury angles overlap with financial management topics, so keep your question on the funding decision itself.

1. How far has the UK Corporate Interest Restriction, with its 30% fixed ratio on tax-EBITDA and £2 million de minimis, pulled leverage down at groups sitting just above the threshold? A regression discontinuity or matched difference-in-differences design could compare groups with net tax-interest expense just over and just under £2 million. Tax-EBITDA and tax-interest are not reported directly, so you will need to approximate them from accounts and say so openly. HMRC’s corporate finance manual overview explains the mechanics. Suits a Master’s project.
2. Did the permanent return of the EBITDA-based Section 163(j) limit, for US tax years beginning after 31 December 2024, loosen borrowing constraints at capital-intensive firms? The 2025 tax law restored the more generous base after several years on an EBIT basis. You could compare firms whose interest sat close to the limit before and after the change. Only one or two years of filings exist so far, so treat this as a design for a Master’s or PhD project and check how much post-change data you can actually obtain.
3. What limits the effect of Pillar Two top-up taxes, with a 15% minimum rate and a €750 million revenue threshold, on where multinational groups place intra-group debt? The UK’s Multinational Top-up Tax and Domestic Top-up Tax apply to accounting periods beginning on or after 31 December 2023 under the Finance (No. 2) Act 2023. Clean estimates are hard so soon, so interviews with group tax directors or a documentary analysis of effective tax rate notes may be more realistic than a large-sample regression.
4. Does the Shyam-Sunder and Myers (1999) financing-deficit test still support the pecking order once firms are split by cash holdings and size? The Frank and Goyal (2003) critique gives you a ready-made reason to split the sample. A single-country sample over ten years is enough for an undergraduate version, while a Master’s project could add a cross-country comparison.
5. How quickly do firms close the gap to target leverage, and is adjustment slower at private firms than at listed ones (Flannery and Rangan, 2006)? Partial adjustment models need a dynamic panel estimator such as system GMM. The free Companies House accounts data product covers electronically filed accounts only, so discuss selection bias before you compare private and listed samples.
6. Does the Baker and Wurgler (2002) external-finance-weighted market-to-book ratio still explain leverage a decade after listing for European firms? The test needs each firm’s history of equity issues, which you can hand-collect from filings if your database lacks it. A fading effect would be as interesting as a persistent one.
7. Why do some listed firms carry no debt at all, and does financial flexibility explain it better than low tax rates (Strebulaev and Yang, 2013)? Identify firms with zero leverage for several years, then compare them with matched peers. An undergraduate version can use three to five firms as case studies and read their annual reports for stated financing policy.
8. Did UK listed firms with a high share of debt maturing within twelve months cut capital expenditure more during the 2022 to 2023 rate rises, following the design of Almeida, Campello, Laranjeira and Weisbenner (2012)? The original studied the 2007 credit crisis, so applying it to a tightening episode is the new angle. Debt maturity tables in annual report notes supply the treatment variable.
9. What has IFRS 16 done to reported leverage and covenant headroom at retailers and airlines since 2019? Operating leases moved onto the balance sheet, so ratios jumped on paper without any change in the business. Compare before and after for ten to fifteen firms, then read the borrowing notes to see whether covenants were defined on the old accounting basis. This works well at undergraduate level because the evidence sits in annual reports.
10. How much of the leverage gap between intangible-heavy and asset-heavy firms closes once R&D and operating leases are capitalised, following Damodaran’s adjustments? Damodaran’s industry datasets publish sector averages you can use as benchmarks, and you can apply the capitalisation yourself to a sample of firms.
11. Do UK defined benefit pension deficits behave like debt in leverage decisions, crowding out borrowing capacity? Treat the IAS 19 deficit as a debt equivalent and test whether firms with larger deficits borrow less. Pension Protection Fund funding data and annual report notes both help. Be careful with discount rate assumptions, which can move a deficit sharply.
12. Do firms close to a credit rating notch issue less debt than firms in the middle of a rating band (Kisgen, 2006)? You need rating histories, which some libraries provide through Compustat or Bloomberg. If yours does not, a hand-collected FTSE 350 sample from annual reports can work.
13. Does permanent full expensing shrink the marginal tax benefit of debt for capital-intensive UK firms by pushing taxable income towards zero? The 100% first-year allowance for main rate plant and machinery was confirmed permanent in the Autumn Statement 2023, and the main corporation tax rate has been 25% since April 2023. Graham’s (2000) simulated marginal tax rate logic lets you estimate how much of the interest tax shield remains usable. The topic pairs two reliefs that are rarely examined together.
14. Do convertible bond announcements at growth-stage listed firms earn the negative returns typical of equity issues, and does a call feature change the result? An event study around regulatory announcements gives the returns. Samples are small for any single market, so pool several European markets and report how you cleaned the dates.

Dividend and Share Buyback Research Topics

Payout research has fresh material because buybacks have grown in the UK. The FCA’s August 2025 review of share buybacks, drawing on Bloomberg data, put buybacks at about 20% of FTSE 350 capital returns in 2017 to 2019 and 42% in 2022 to 2024. That shift gives you a trend to explain rather than just describe.

15. How do structured buyback products, such as guaranteed discount and outperformance sharing, compare with plain open-market programmes on execution price against the period VWAP at FTSE 100 issuers? The FCA review describes these products and which issuers favour them. Daily buyback announcements through the Regulatory News Service give prices and volumes, which you can compare with market VWAP for the same dates. Suits a Master’s project.
16. Does earnings volatility or a preference for flexibility better explain the shift from dividends to buybacks across the FTSE 350 (Brav, Graham, Harvey and Michaely, 2005)? Decompose payout by year, then test the flexibility hypothesis at firm level. That turns a headline trend into a testable claim.
17. Does the US 1% excise tax on net share repurchases above $1 million, which applies to repurchases after 31 December 2022, push firms from buybacks towards dividends or simply lower net buybacks? The tax covers domestic listed corporations and is netted against shares issued in the same year, so measure net repurchases rather than gross. A difference-in-differences design against non-US listed peers is the obvious start, with care for firms that issue large amounts of employee stock.
18. Do repurchases cluster in quarters where earnings per share would otherwise miss consensus, and do FTSE 350 remuneration committees adjust EPS targets for buybacks (Almeida, Fos and Kronlund, 2016)? Analyst forecast data from LSEG IBES, available through WRDS at many universities, supplies the consensus, and remuneration reports show whether targets are adjusted. A qualitative reading of twenty reports can complement the statistics.
19. Does Lintner’s (1956) partial adjustment model describe dividend smoothing equally well for FTSE 100 and FTSE 250 firms? Estimate each firm’s target payout ratio and speed of adjustment, then compare the two indices. The model is simple enough for an undergraduate project, and the comparison gives it a real question.
20. How large is the ex-dividend share price drop relative to the dividend for FTSE 350 stocks, and what does the ratio imply about marginal investors’ tax rates (Elton and Gruber, 1970)? A short event window and daily prices are enough. Compare the ratio across high-yield and low-yield stocks to see whether tax clienteles show up. It is quick to run and easy to explain.
21. Do special dividend announcements earn different abnormal returns from regular dividend increases, and does signalling or temporary excess cash explain the gap? Run an event study around announcements and split the sample by cash holdings and prior payout history. Separate the two types carefully, because some firms label recurring payments as special.
22. What triggers a first dividend at profitable listed technology firms, and do initiators outperform matched non-payers (Fama and French, 2001)? Fama and French documented a falling share of payers over time. A sample of first-time payers lets you test whether maturity or investor demand drives initiation. Define “profitable” before you build the sample.
23. How do finance directors establish distributable reserves under Part 23 of the Companies Act 2006 when subsidiary profits are trapped below the parent? Interviews with finance directors or company secretaries, or a case study of a group reorganisation, would suit this question. It sits between corporate finance and company law, so a doctrinal angle works as well.
24. Which UK listed firms cancel repurchased shares and which hold them in treasury, and does the choice relate to employee share plan needs? Regulatory announcements state the intention for each programme, so you can classify a sample without a paid database. A plain descriptive study can still reveal a pattern worth testing.

Capital Budgeting, Cost of Capital and Valuation Topics

Valuation topics reward careful sensitivity work more than clever models. Most of these use free or widely available inputs, so you can finish them without an expensive database.

25. How much does a DCF value for FTSE 100 firms change when an implied equity risk premium replaces a fixed historical premium, and which input matters most: the premium, the risk-free rate or terminal growth? Build a transparent valuation template, then run one-at-a-time and joint sensitivities. Published premium estimates are refreshed during the year, so state the date you used.
26. Which beta estimation choices move the cost of equity most for FTSE 250 firms: return frequency, window length or benchmark index? Estimate daily, weekly and monthly betas over two and five years against local and global indices, then compare the implied cost of equity. Suitable for undergraduates who can handle a regression in Excel or R.
27. When leverage is expected to change over a project’s life, how far do adjusted present value (Myers, 1974) and WACC valuations diverge? A single infrastructure or buyout case, valued both ways, can show where the gap comes from. Test how sensitive each answer is to the tax shield and distress cost assumptions.
28. Can an abandonment option explain why mining and oil firms keep marginal assets running (Brennan and Schwartz, 1985)? Use a binomial tree with commodity price scenarios and compare the option value with a plain NPV. Reserve reports and annual reports provide the operating costs.
29. Do UK finance directors still rely on payback and IRR alongside NPV, and what hurdle premiums do they add, in the spirit of Graham and Harvey (2001)? This is a survey replication, so it needs primary data and ethics approval. Response rates from senior finance staff are usually low, so a sample size calculator can help you decide whether fifteen to twenty interviews is the more honest design.
30. Do the Kaplan-Zingales, Whited-Wu and Hadlock-Pierce indices classify the same UK firms as financially constrained, and does the answer change an investment result (Farre-Mensa and Ljungqvist, 2016)? Compute all three for one sample and report the overlap. Then re-run a simple investment regression under each classification.
31. Has investment-cash flow sensitivity (Fazzari, Hubbard and Petersen, 1988; critiqued by Kaplan and Zingales, 1997) fallen after firms gain access to public bond markets? Identify the year each firm first issues a public bond and compare sensitivity before and after. The debate between the two papers gives you both sides of your literature review.
32. Do private UK firms invest less responsively to growth opportunities than listed peers, as Asker, Farre-Mensa and Ljungqvist (2015) found in the US? Private firms have no share price, so use industry median valuation ratios as the growth proxy. Filed accounts supply investment data, and you should state which firms file full accounts.
33. Did permanent full expensing, a 100% first-year allowance, raise plant and machinery investment at companies above the £1 million Annual Investment Allowance? Full expensing started in April 2023 and was later made permanent. Compare firms above and below the allowance threshold before and after, and note that leased assets were excluded from the relief. Suits a Master’s project.
34. Do earnings multiples or discounted cash flows give smaller pricing errors for UK mid-caps, repeating Kaplan and Ruback (1995) on current data? Value thirty to fifty firms both ways using forecasts available at the valuation date, then compare with later market prices. Take care to avoid look-ahead bias.
35. Is there still a diversification discount among UK listed conglomerates when excess value is calculated from IFRS 8 segment data (Berger and Ofek, 1995)? Segment disclosures give each business unit’s sales and assets, so you can impute stand-alone values from single-segment peers. Be open about how segments are matched.
36. Which cost-of-equity model predicts realised returns better for FTSE 350 firms: CAPM, the Fama-French three-factor model or an implied model (Claus and Thomas, 2001)? The Kenneth French data library publishes factor returns, including for Europe. Compare model fit across portfolios and report how you handled thin trading.
37. Do groups with divisions of different risk apply one company-wide WACC, and how much value does that destroy compared with pure-play divisional betas? A case study of one diversified group can show the mispricing in concrete numbers. Annual reports and segment notes supply the cash flows, and comparable single-business firms supply the betas.
38. How do the financing mix and WACC of two listed UK supermarket groups differ once leases and pension deficits are counted, and what explains the gap? This plain case comparison suits undergraduates. Use annual reports for the capital structure and sector betas for the cost of equity, then explain differences using strategy and asset ownership.

Mergers, Acquisitions and Takeover Dissertation Ideas

Takeover research works best when you pick a mechanism, such as the method of payment, the bidder’s identity or a Code rule, and then test it on deals. Many questions straddle finance and law, so doctrinal angles pair well with corporate law dissertation topics if your course allows it.

39. How do the Takeover Code changes in force from 4 February 2026 treat share buybacks that push a shareholder’s holding towards the 30% Rule 9 threshold? The Panel changed how the Code applies on a buyback, alongside changes for dual class share structures and IPO disclosure. A doctrinal analysis with two or three worked scenarios suits a Master’s project. Read the Panel’s own notes and law firm commentary side by side, because the detail matters.
40. Where should the Takeover Code draw the line on reverse takeovers, and how would a broader definition change deal structuring and information equality? The Panel’s consultation paper PCP 2026/1 proposed treating any acquisition by a Code company that may need shares above 100% of its existing capital as a reverse takeover. The consultation closed on 2 October 2026, so check the Panel for its response statement and final text before you rely on the proposal.
41. Do overseas bidders pay different premiums for UK targets than UK bidders once target size and sector are controlled? Firm offer announcements under Rule 2.7 give the offer price, and you can measure the premium against the undisturbed share price. A sample over several years is feasible without a paid deals database, though one would speed the work. Suits undergraduate or Master’s level.
42. Do bidders buying private targets with shares earn higher announcement returns than bidders buying listed targets, as Fuller, Netter and Stegemoller (2002) reported? Split deals by target status and method of payment, then test whether paying in shares reverses the private-target effect. Private target data is patchy, so explain how you identified deals.
43. Do successive acquisitions by FTSE 350 serial acquirers earn lower announcement returns, as Roll’s (1986) hubris hypothesis would suggest, or do acquirers learn? Number each firm’s deals in sequence and test whether returns decline or recover. Add deal size and payment method as controls.
44. How much of the purchase price do UK acquirers allocate to goodwill under IFRS 3, and does a high goodwill share predict later impairment (Li and Sloan, 2017)? Hand-collect purchase price allocations for twenty to thirty deals from annual reports and follow each acquirer’s impairments for several years. A plain, data-light design that still tests a real claim.
45. Do earnouts reduce overpayment in acquisitions of private targets (Cain, Denis and Denis, 2011)? Contingent consideration notes under IFRS 3 show where earnouts were used. Compare later write-downs or adjustments for deals with and without them. Suits a Master’s project with careful hand collection.
46. How effective are inducement fees and other offer-related arrangements, restricted by Rule 21.2 of the Takeover Code, in deterring competing bids? Combine a doctrinal reading of the rule with a case sample of contested bids. Count how often a rival appeared where a fee was agreed and where it was not.
47. Are take-private premiums for UK mid-cap targets explained by undervaluation, control rights or the bidder’s leverage capacity? Compare offer premiums with the target’s valuation multiples against peers, then add bidder financing details from offer documents. Interviews with advisers can test the explanations you find.
48. How does the ban on frustrating action in Rule 21 shape bid outcomes compared with US poison pill defences? A comparative design using a handful of matched contested bids in each system suits a Master’s or PhD project. Focus on what boards could and could not do once a bid was in sight.
49. Do activist campaigns at UK listed companies precede takeover bids, and how does Practice Statement 26 on shareholder activism treat acting in concert? Build a sample of public campaigns, then check whether a bid followed within a defined window. Pair the empirical result with a short doctrinal discussion of concert party risk.
50. Do spin-offs create value mainly by becoming takeover targets, as Cusatis, Miles and Woolridge (1993) argued? Track European spin-offs and their parents for several years, noting which were later acquired. Separate the announcement return from the later takeover effect.

IPO, Listing and Private Capital Research Topics

UK market rules have changed in three steps: the UK Listing Rules reforms of July 2024, a new public offers regime in January 2026 and the PISCES private market from 2026. Each gives you a development to study, though samples are small and early, so choose designs that suit thin data.

51. What do the UK Listing Rules reforms of 29 July 2024, including disclosure-based eligibility and weighted voting rights for institutions, change for IPO pricing and governance at newly listed firms? Interviews with equity capital markets advisers or company secretaries could capture what has changed in practice. Samples of new listings are small, so a qualitative design is often more convincing than a regression.
52. Did ending mandatory shareholder votes on significant and related party transactions, from 29 July 2024, change announcement returns on large deals at UK listed firms? Significant transactions at the 25% threshold now require disclosure rather than a vote. An event study of deals before and after the change is feasible, though you should compare like with like on deal size. Suits a Master’s project.
53. How much of the cost saving from the Public Offers and Admissions to Trading Regulations, in force from 19 January 2026, reaches FTSE 250 issuers raising secondary equity? The regime replaced the UK Prospectus Regulation and exempts most public offers by publicly traded issuers from a prospectus requirement, while admission to a regulated market still needs one. The FCA’s policy statement PS25/9 sets out the rules. Evidence is thin so soon, so interviews with equity capital markets bankers and company secretaries may be the strongest design.
54. What have the first PISCES trading events in March 2026 shown about liquidity and price discovery for private company shares? Case studies of the JP Jenkins Private Market and the London Stock Exchange’s Private Securities Market can draw on operator rules, order windows and intermediary commentary. Few events have taken place, so frame the work as an early case study rather than a statistical test.
55. Does Rock’s (1986) winner’s curse model or Benveniste and Spindt’s (1989) bookbuilding theory better explain the underpricing of UK IPOs priced below, within and above the initial range? Price ranges and final prices come from prospectuses and pricing announcements. Compare first-day returns across the three groups, since the two theories make different predictions about them.
56. Does Ritter’s (1991) long-run IPO underperformance survive size and book-to-market matching for UK and Nasdaq technology listings? Compute three-year abnormal returns against matched firms and against Fama-French factor models, then compare the answers. Different benchmarks often change the result, which is the point.
57. Why do firms leave public markets, and does the UK Listing Rules requirement for a shareholder vote to cancel a listing protect minority holders when a controlling shareholder is present? Build a sample of delistings and classify each as a takeover, a voluntary cancellation or a failure. Then read the voting outcomes in the circulars to see how much protection the vote gave minority holders.
58. Is a US cross-listing still associated with higher valuation for non-US firms, or has the premium faded (Doidge, Karolyi and Stulz, 2013)? Compare cross-listed firms with matched home-market peers over time. The question links directly to international finance research topics if you want a wider frame.
59. How should IPO documents describe Rule 9 mandatory offer risk for controlling shareholders, and does the February 2026 Takeover Code disclosure requirement change investor demand? The amended Code requires IPO documents to disclose controlling shareholders and concert parties expected to hold 30% or more of voting rights. Few IPOs fit yet, so treat this as a doctrinal and qualitative study.

Financial Distress and Restructuring Dissertation Topics

Distress research needs a clear definition of failure before anything else. Decide whether you mean administration, liquidation, default or a restructuring plan, then keep that definition consistent across your sample.

60. Which predicts UK listed firm failure better out of sample: Altman’s (1968) Z-score or a Merton (1974) distance-to-default model? Identify failures from administration and liquidation notices, then compare predictive accuracy using ROC curves. Both models are easy to explain, so the comparison works well at Master’s level.
61. How many UK listed and large private firms meet the BIS definition of a zombie, interest coverage below one for three consecutive years and an age of at least ten years, and do they crowd out investment at healthy peers? The definition comes from Banerjee and Hofmann (2018). Test whether sectors with more zombies show lower investment among non-zombies. Interest cover is sensitive to the rate cycle, so report results for more than one period.
62. Do Part 26A restructuring plans with cross-class cram-down, available since 26 June 2020, deliver better creditor recoveries than the relevant alternative of administration for similar firms? The court tests each plan against the outcome most likely without it, using valuation evidence. Published plan documents and judgments supply the data, and commercial law dissertation topics can help if your course leans towards law. Recoveries are rarely observed in full, so describe your proxies.
63. Do debt-for-equity swaps improve post-restructuring operating performance more than amend-and-extend deals? A matched case-study design of eight to twelve restructurings can track margins, capital expenditure and leverage for three years after each deal. Be clear about how you chose the comparison cases.
64. Do going-concern and viability statements in FTSE 350 annual reports predict later distress, and did the FRC’s February 2025 guidance on solvency, liquidity and going concern change what boards disclose? Text analysis of the statements before and after the guidance would give you a measurable change. Link disclosure tone to later failures or rescue financings.
65. What do administrators’ progress reports show about direct costs of administration at UK retailers as a share of realisations? The reports are public, so a plain descriptive study of ten to fifteen cases is feasible. Compare fees with realised asset values and discuss what drives the ratio.

Corporate Risk, Liquidity and Working Capital Topics

Risk and liquidity questions sit close to risk management dissertation topics, so keep yours on the firm’s own funding and exposure choices. Many of these can be done with annual reports alone.

66. Why do European listed firms hold so much more cash than they used to, and does the Bates, Kahle and Stulz (2009) explanation of riskier cash flows and lower inventories still fit? Replicate the cash-to-assets trend for a European sample and test the same two drivers. A clean replication with a new region is a respectable Master’s contribution.
67. Does the link between the cash conversion cycle and profitability turn non-linear for UK manufacturers, as Baños-Caballero, García-Teruel and Martínez-Solano (2014) found in Spanish firms? A squared term in a panel regression tests for an optimal working capital level. Plain enough for an undergraduate project with five to ten years of data.
68. Do large UK firms stretch supplier payment times before financial distress? The government’s payment practices reports are published twice a year and can be downloaded. Match them to later failures or going-concern warnings and compare payment times before and after distress signals.
69. Have the amended IAS 7 and IFRS 7 supplier finance disclosures, effective for periods beginning on or after 1 January 2024, revealed hidden reliance on reverse factoring? Read the new notes at retailers and manufacturers, then compare reported leverage with leverage that counts these payables as debt. Suits undergraduates and Master’s students.
70. Do UK multinationals that disclose foreign currency derivatives trade at a Tobin’s q premium, after dealing with endogeneity (Allayannis and Weston, 2001)? Use derivative disclosures to flag hedgers and an instrument or matching approach to address self-selection. Discuss why the result might reflect firm quality rather than hedging.
71. Did fuel hedging reduce cash flow volatility at European airlines during the 2022 price spike (Carter, Rogers and Simkins, 2006)? Annual reports disclose hedge ratios and fuel costs, so a case comparison of six to ten airlines is feasible. Compare operating cash flow swings across high and low hedgers.
72. Are cash holdings and hedging substitutes for managing liquidity risk (Disatnik, Duchin and Schmidt, 2014)? Test whether firms with more cash hedge less, controlling for size and leverage. A negative relation would support substitution, but check that hedging disclosures are comparable across firms.
73. How exposed are UK mid-caps to floating-rate debt, and did the 2022 to 2023 Bank Rate rises show up in interest cover differently for hedged and unhedged borrowers? Debt notes give the fixed-floating split and any swaps. A small sample with careful reading can outperform a large one with noisy data.

Governance, Ownership and Incentives in Corporate Finance Research

Board and ownership questions overlap with governance-led dissertation ideas. The topics here keep the angle on how governance changes financing, payout or deal choices, and several depend on rules that are still new.

74. What does a board’s declaration on the effectiveness of material controls under UK Corporate Governance Code Provision 29 tell lenders and investors, and how do markets price an ineffective-controls disclosure? Provision 29 applies to financial years beginning on or after 1 January 2026, so the first full set of UK declarations is only now arriving. US internal control weakness disclosures under Sarbanes-Oxley Section 404 give you an established analogue in the meantime. Suits a Master’s project.
75. Do broader malus and clawback provisions, covered by Code Provisions 37 and 38, reduce earnings management at FTSE 350 firms? The 2024 Code expects directors’ contracts to include malus and clawback and the remuneration report to describe them, for accounting periods beginning on or after 1 January 2025. A descriptive study of how firms word their triggers is a sensible first stage, followed by tests on discretionary accruals once enough reports exist.
76. Did Delaware’s SB 21 safe harbour for controlling stockholder transactions, signed on 25 March 2025 and upheld by the Delaware Supreme Court on 27 February 2026, change the valuations of controlled Delaware companies? An event study around the bill’s key dates, comparing controlled firms with non-controlled peers, is the natural design. Court decisions can shift expectations too, so mark each date carefully.
77. Do firms that reincorporate from Delaware to Nevada or Texas gain or lose value, revisiting the Delaware premium (Daines, 2001)? Use announcement dates and shareholder vote dates for an event study. Separate controlled and widely held firms, since the new statutes may matter more for controlled ones.
78. Do family-controlled FTSE 250 firms hold more cash and pay lower dividends than widely held peers (Anderson and Reeb, 2003)? Identify family control from annual report ownership tables. Matching on size and sector makes a fair comparison, and even the descriptive results can fill a short undergraduate chapter.
79. Does CEO inside debt, such as pensions and deferred pay, reduce leverage and risk-taking at FTSE 350 firms (Edmans and Liu, 2011)? Remuneration reports disclose pension values. Test whether CEOs with larger inside debt run lower leverage, and report how you handled outliers.
80. Do boards with more women directors make fewer or smaller acquisitions (Levi, Li and Zhang, 2014)? Board composition data are public for FTSE 350 firms. Control for size, cash and growth, and discuss why the result might not be causal.
81. How do boards explain departures from the UK Corporate Governance Code, and does explanation quality affect valuation (Arcot, Bruno and Faure-Grimaud, 2010)? Code the explanations for specificity, then link them to returns or valuation ratios. The same approach will apply to the UK Sustainability Reporting Standards, where the FCA’s rules also use comply or explain.
82. Do FTSE 350 CEOs who buy and hold their own company’s shares make more acquisitions, as an overconfidence proxy would suggest (Malmendier and Tate, 2005)? Director dealing announcements show personal purchases. The question connects corporate finance to behavioural finance topics without leaving the firm’s own decisions.

Sustainability and Climate Finance Topics for Companies

Sustainability rules moved quickly in 2026, which creates good questions and a lot of risk of writing about rules that have changed. Where a topic below depends on a recent rule, check the regulator’s page for its latest status. If your interest leans towards social impact rather than financing, CSR dissertation ideas may fit better.

83. Do TCFD-aligned climate disclosures lower the cost of debt for FTSE 350 issuers, and what should the move to UK SRS S2 add? The FCA’s policy statement PS26/19 replaces TCFD-aligned listing rules with comply-or-explain reporting against UK SRS S1 and S2 for accounting periods beginning on or after 1 January 2027, with first reports in 2028 and transitional relief for Scope 3 and non-climate disclosures. Study today’s TCFD disclosures against loan or bond spreads, then explain what the new regime would change.
84. How will boards explain non-compliance with UK SRS S1 and S2, and what can early voluntary adopters show? The standards have been available for voluntary use since 25 February 2026. A documentary analysis of the first voluntary reports, coding what firms disclose and what they leave out, suits a PhD proposal or a strong Master’s project.
85. Did the narrowing of CSRD to companies with more than 1,000 employees and €450 million of net turnover change the cost of capital of firms that moved out of scope? The Omnibus Directive came into force on 18 March 2026. Run an event study around the Commission’s February 2025 proposal and the 9 December 2025 political agreement, comparing firms moved out of scope with those that stayed in. Suits a Master’s or PhD design.
86. How should an importer model CBAM certificate costs, with the definitive period running from 1 January 2026 and certificates purchasable from 1 February 2027 for 2026 imports, in capital budgeting for steel, aluminium or fertiliser supply chains? Build scenarios for carbon price, pass-through and supplier emissions data, then compare project NPV with and without the cost. The European Commission’s CBAM page explains the scheme, and importers below an annual 50 tonne threshold are not required to apply for authorised declarant status. A single-company case study works best.
87. Do sustainability-linked bonds carry a pricing premium or discount, and how far do the FCA’s added disclosure expectations for sustainability-labelled debt, which the FCA says took effect on 19 January 2026, affect issuer costs? Compare spreads against similar conventional bonds from the same issuer where you can. Bond data usually comes from Bloomberg or LSEG, so confirm your access before you commit.
88. Do green bond issuers improve environmental performance after issuing, as Flammer (2021) reported? Replicate the idea with European issuers using carbon intensity before and after issuance. Issuer frameworks identify the green label, and sustainability reports supply the outcome measure.
89. Does disagreement between ESG rating providers raise bond spreads for European issuers (Berg, Koelbel and Rigobon, 2022)? You need ratings from at least two providers, so check what your library offers. If access is limited, build a smaller hand-collected sample and say plainly where the limits lie.
90. Do FTSE 100 climate transition plans line up with disclosed capital expenditure plans? The government has been considering whether to require transition plans from listed companies. Compare stated targets with capex guidance and project pipelines in annual reports, then score the match. This documentary design needs no database.
91. Does a larger share of contracted, government-backed revenue explain lower costs of capital at listed renewable generators? Compare revenue contract mix with the implied cost of equity and the cost of debt disclosed in the notes. Damodaran’s sector betas offer a benchmark for the equity side.

Disclosure, Reporting and Information Topics in Corporate Finance

Disclosure topics sit on the border with accounting and finance topics. Keep your outcome a financing or valuation variable, such as the cost of capital or issuance, and the project stays in corporate finance.

92. How far can a non-statutory FRC provide the investor assurance that ARGA was designed to deliver, and did investors price the 20 January 2026 decision to drop the Audit Reform Bill? The government announced it would not proceed with the bill, so the FRC remains the regulator without the planned statutory body. An event study around the announcement, or interviews with audit committee chairs, could test the assurance question. Several news items overlap on that date, so be honest about confounding.
93. Did FTSE 350 annual reports change their fraud-prevention disclosures after the corporate offence of failure to prevent fraud took effect on 1 September 2025? The offence applies to large organisations, so check the current size tests on GOV.UK before you define your sample. Text analysis of reports before and after, plus a look at investor reactions, forms a Master’s design.
94. Does the level of voluntary disclosure in FTSE 250 annual reports lower the implied cost of equity, repeating Botosan (1997) with the Claus and Thomas (2001) implied cost measure? Score disclosure with a transparent checklist, then test the link. A reproducible scoring rule matters more than a large sample.
95. Did MiFID II research unbundling change analyst coverage and equity issuance differently for Main Market and AIM small caps (Fu, Jenkinson, Newton and Xie, 2024)? Their evidence shows a drop in Main Market coverage, with a smaller effect on AIM firms where nominated advisers often provide research. Extend that work to financing outcomes such as issuance or the cost of equity.

Fintech and Corporate Treasury Dissertation Ideas

Technology topics work in corporate finance when the question is about funding, treasury or risk, not the technology itself.

96. Does gradient boosting beat Altman’s Z-score and Ohlson’s O-score at predicting the failure of UK SMEs using Companies House filings? Companies House publishes accounts data for electronically filed accounts, so check coverage and licence terms before you build the sample. Split training and test sets by time to avoid leakage. Suits a Master’s student with some coding skill.
97. How are treasury teams in mid-sized firms using AI in cash forecasting, and what stops adoption? A qualitative interview study with ten to fifteen treasurers or finance managers can explore forecasting accuracy, governance and data quality. Secure ethics approval and agree anonymity before you recruit.
98. What benefits and costs do issuers report from using the Digital Securities Sandbox compared with conventional bond issuance? The sandbox lets firms test digital issuance and settlement. Evidence is limited, so a case-based design built on regulator publications and issuer announcements suits a Master’s project.

SME, Crowdfunding and Entrepreneurial Finance Topics

Smaller firms face different constraints from listed ones, so these ideas connect closely to entrepreneurship dissertation topics. Most can use public filings plus a small primary sample.

99. How do Public Offer Platforms, introduced with the new public offers regime from 19 January 2026, differ from existing crowdfunding platforms in disclosure and investor protection? Compare the FCA rules with current platform practice for a small number of operators. A doctrinal comparison is realistic while market data remains thin.
100. Do UK equity crowdfunding campaigns that beat their target attract later institutional funding rounds? Platform pages show campaign outcomes, and Companies House share allotment filings help track later rounds. Control for sector and campaign size, and note that follow-on funding could reflect company quality rather than the campaign.
101. Do UK SMEs use trade credit as a substitute for bank credit when lending tightens (Petersen and Rajan, 1997)? Balance sheets give trade creditors and bank debt for each year. Compare changes around credit conditions and control for sector.
102. Do owner-managers follow Berger and Udell’s (1998) financial growth cycle, or does a pecking-order preference for internal funds fit better? Interviews with ten to fifteen owner-managers about how they funded each growth stage let you compare both theories. The method is plain enough for undergraduate level, provided you follow good ethics practice.
103. Do corporate venture capital arms generate more patent citations for the parent than independent venture capital does (Chemmanur, Loutskina and Tian, 2014)? Patent data and investment records are public, though matching them takes care. This is a strong PhD or advanced Master’s design.

How to Narrow a Corporate Finance Idea into a Research Question

A topic becomes a project when five choices are fixed. Make them in this order, because each one limits the next.

• The trigger: a decision, rule change or event, such as a buyback programme or an interest limitation rule.
• The comparison: firms that were affected against firms that were not, or the same firms before and after.
• The outcome: one measurable variable, such as net leverage, abnormal return or capital expenditure.
• The window: the years or days you will observe, set before you look at results.
• The data check: proof that the data exists for enough firms before you commit.

Take topic 17 as an example. The trigger is the US buyback excise tax, the comparison is non-US listed firms, the outcome is the share of payout made through net repurchases, the window runs from 2019 to 2025, and the data check confirms you can obtain issuance and dividend figures. The guide on writing a research question shows how to phrase the result, and the research question generator can test your wording. If your question is settled and you need the next document, how to write a dissertation proposal covers the structure.

Corporate Finance Dissertation Examples: Aims and Objectives

Four topics from the list, turned into an aim and objectives at different levels. Each objective produces something you can check.

Undergraduate example: IFRS 16 and covenant headroom (topic 9)

Aim: To measure how adopting IFRS 16 changed reported leverage and covenant headroom at twelve UK listed retailers between the 2018 and 2020 financial years.

1. To calculate net debt to EBITDA and gearing for each retailer before and after lease capitalisation, using annual report restatements.
2. To identify whether each retailer’s borrowing agreements define covenants on pre-IFRS 16 or post-IFRS 16 terms.
3. To compare covenant headroom under both bases and explain the differences.

Master’s example: the US buyback excise tax (topic 17)

Aim: To test whether the US 1% excise tax on net share repurchases changed the share of payout made through buybacks at US listed firms, relative to non-US listed peers, between 2019 and 2025.

1. To construct net repurchase and dividend measures for matched US and non-US samples, netting issuance as the tax does.
2. To estimate a difference-in-differences model with firm and year fixed effects.
3. To test whether firms with repurchases close to the $1 million threshold respond differently from larger repurchasers.

Master’s example: full expensing and investment (topic 33)

Aim: To estimate whether permanent full expensing raised plant and machinery investment at UK companies above the £1 million Annual Investment Allowance relative to companies below it.

1. To extract plant and machinery expenditure from accounts filed for the 2021 to 2025 period.
2. To define treatment and comparison groups using the allowance threshold.
3. To estimate the investment response with firm fixed effects and discuss the exclusion of leased assets.

PhD-level design: CSRD scope and the cost of capital (topic 85)

Aim: To measure how investors priced the narrowing of CSRD scope for firms that moved outside the new thresholds, around the February 2025 proposal and the 9 December 2025 political agreement.

1. To classify EU listed firms against the 1,000 employee and €450 million turnover tests using financial statement data.
2. To estimate cumulative abnormal returns around the two announcement dates for firms moved out of scope and firms that remained in scope.
3. To test whether the results differ by each firm’s prior sustainability reporting quality.

To draft your own, try the aims and objectives generator and then check each objective against your data.

Which Method Suits Your Corporate Finance Dissertation?

Pick the method after you have a question. The table matches common corporate finance dissertation designs to the evidence they need and the problems that catch students out.

Method	Best for	Typical evidence	Watch out for
Event study	Announcement effects of buybacks, deals or rule changes	Share prices and announcement dates	Overlapping events, thin trading, confounding news
Panel regression with fixed effects	Relationships across firms and years, such as leverage or investment	Accounts and ownership data	Endogeneity, survivorship bias, outliers
Difference-in-differences	Rule changes with affected and unaffected firms	Accounts or prices before and after	Parallel trends, spillovers between groups
Interviews or survey	How finance directors actually decide	Primary data from managers	Access, low response rates, ethics approval
Case study	One deal, restructuring or rule	Filings, announcements and documents	Generalising from one case, choosing the case
Doctrinal or regulatory analysis	What a rule requires and how it operates	Codes, statutes, consultation papers, judgments	Rules change, so state your position date
Text analysis	Changes in disclosure	Annual reports and announcements	Coding reliability, clear definitions

If you are unsure which test fits your data, the statistical test selector narrows the choice. Once you have decided, the guide to writing a dissertation methodology shows how to justify it.

Where to Find Corporate Finance Data for Your Dissertation

Match your evidence to your topic before you fall in love with a title. These routes cover most of the list.

• Free UK company evidence: Companies House accounts data for electronically filed accounts, Regulatory News Service announcements, FCA and Takeover Panel documents, and the government’s payment practices reports.
• Free valuation inputs: Damodaran’s datasets and the Kenneth French factor library.
• Licensed databases: WRDS, which carries Compustat, CRSP, ExecuComp and event study tools, plus LSEG and Bloomberg. Access varies by university, and some allow undergraduates to use WRDS for dissertations while others do not, so ask your library first.
• US filings: SEC EDGAR is free and covers most US listed firms.
• International context: World Bank, IMF, OECD, Eurostat and ECB sources help if you study outside the UK or want a cross-country comparison.

Whatever you choose, check each dataset’s coverage, definitions and licence terms. Missing years and changes in reporting rules can quietly change your results.

Corporate Finance Dissertation Topics by Academic Level

Undergraduate topics: one decision, one outcome, a sample you can finish

Choose a topic where the evidence sits in annual reports or free datasets and the method is a ratio comparison, a simple regression or a case study. Topics 7, 9, 19, 20, 26, 37, 38, 44, 65, 67, 68, 71, 78 and 102 fit this profile. A small, well-explained sample beats a large one you cannot defend.

Master’s topics: a clear identification strategy

Expect to justify your design, not just run it. Topics 1, 5, 8, 15, 17, 18, 29, 30, 33, 42, 45, 52, 60, 64, 69 and 93 suit a Master’s project because each has a defined comparison and available evidence. If you want a second opinion on scope, finance dissertation support is available, and the wider finance dissertation topics hub shows neighbouring areas.

PhD topics: a contribution beyond replication

A doctoral project needs a defensible contribution, so favour questions where rules or data are new. Topics 2, 6, 13, 55, 61, 76, 77, 85 and 89 offer that room, but each still needs a literature review that proves the gap. Do not choose a topic because it sounds complicated.

Common Mistakes in Corporate Finance Research Projects

A short guide on how to choose research topics covers the general problems. These are the ones that catch corporate finance students most often.

• Treating correlation as cause. Leverage, profitability and firm value are all driven by the same underlying factors, so a regression alone rarely proves direction.
• Survivorship bias. A sample of firms listed today leaves out the ones that failed, which flatters results on leverage and risk.
• Look-ahead bias. Valuation tests must use only information available at the valuation date.
• Overlapping event windows. If two announcements fall in one window, you cannot tell which moved the price.
• Building on a proposal as if it were law. A consultation paper is not a rule. State the status and date of every regulatory detail you use.
• Relabelling the same idea. Changing the country, year or industry does not make a new topic. State the new mechanism or the new data that makes the question different.

Corporate Finance Dissertation Questions Answered

Can I write a corporate finance dissertation without a paid database?

Yes. Annual reports, Companies House accounts data, regulatory announcements and the Damodaran and French datasets support many topics on this list, including 5, 9, 44, 65, 68 and 73. Paid databases save time, but they are not essential if you design around free evidence.

Should I choose an event study or a panel regression?

Use an event study when you want the market’s immediate reaction to a dated announcement. Use a panel regression when you want a relationship that unfolds across firms and years. If a rule change affects some firms and not others, a difference-in-differences design usually answers the question more convincingly than either.

Do I need a UK sample?

No. Corporate finance does not depend on one country, and several topics here use US, European or cross-country samples. Pick the market you can get data for and understand. If you adapt a UK topic, replace the UK rule with your own country’s equivalent and check how its details differ.

How current does a corporate finance topic need to be?

It needs to be answerable, not fashionable. A classic question tested on new data or after a new rule can be stronger than a headline topic with no usable evidence. If you use a recent rule, check its status and effective date, because proposals and consultations change.

Are interviews with finance directors realistic?

They can be, but access is the obstacle. Senior finance staff are busy, and ethics approval takes time. Plan for a small sample, use your university’s contacts and alumni networks, and treat the interviews as depth rather than proof. Topics 23, 29, 51, 53, 97 and 102 all use this approach.

Choosing Your Corporate Finance Dissertation Topic and Moving On

Shortlist two or three topics that pass the data test, then write each as a single question with a trigger, comparison, outcome and window. Plan your stages with the dissertation timeline planner before you start collecting data, and if you want the proposal checked, research proposal support can help you tighten it. Use these corporate finance dissertation topics as starting points for your own research, and follow your institution’s policies on topic approval, referencing and academic integrity.
