J Armour and D.J. Cumming, 'Bankruptcy Law and Entrepreneurship' (2008) 10 American Law and Economics Review 303 [...]

DOI: doi:10.1093/aler/ahn008

Recent initiatives in a number of countries have sought to promote entrepreneurship through relaxing the legal consequences of personal bankruptcy. Whilst there is an intuitive link, relatively little attention has been paid to the question empirically, particularly in the international context. We investigate the relationship between bankruptcy laws and entrepreneurship using data on self-employment over 16 years (1990–2005) and fifteen countries in Europe and North America. We compile new indices reflecting how "forgiving" personal bankruptcy laws are. These measures vary over time and across the countries studied. We show that bankruptcy law has a statistically and economically significant effect on self-employment rates when controlling for GDP growth, MSCI stock returns, and a variety of other legal and economic factors.

J Armour, 'Enforcement Strategies in UK Corporate Governance: A Roadmap and Empirical Assessment' in John Armour and Jennifer Payne (eds), Rationality in Company Law (Hart Publishing 2009) [...]

Shares in publicly-quoted UK companies are, similarly to those in their US counterparts, dispersed amongst many holders. The central problem of corporate governance for UK listed firms is therefore rendering managers accountable to shareholders. This paper investigates the way in which the mechanisms used to control these managerial agency problems are enforced. It provides a roadmap of the enforcement strategies employed, and a first approximation of their empirical significance. The results suggest three stylised facts about the UK corporate governance system. First, shareholder lawsuits are conspicuous by their absence. Formal private enforcement plays little or no role in controlling managers. Secondly, and contrary to leading accounts in the economic literature, it is public, rather than private, enforcement which dominates in relation to listed companies. However, the lion's share of the interventions by the relevant agencies - the Takeover Panel, the Financial Reporting Review Panel, and the Financial Services Authority - is of an informal character, not resulting in any legal action. Suasion, rather than sanction, is the order of the day. Thirdly, a simple divide between public and private enforcement fails fully to take account of the role played by institutional investors in the UK, who have engaged systematically in informal private enforcement activity. Strong informal private enforcement has historically therefore been the flipside, in the UK, of weak formal private enforcement.

J Armour and W.-G. Ringe, 'European Corporate Law 1999-2010: Renaissance and Crisis' (2011) 48 Common Market Law Review 125 [...]

European corporate law has enjoyed a renaissance in the past decade. Fifteen years ago, this would have seemed most implausible. In the mid–1990s, the early integration strategy of seeking to harmonize substantive company law seemed to have been stalled by the need to reconcile fundamental differences in approaches to corporate governance. Little was happening, and the grand vision of the early pioneers appeared more dream than ambition. Yet since then, a combination of adventurous decisions by the Court of Justice, innovative approaches to legislation by the Commission, and disastrous crises in capital markets has produced a headlong rush of reform activity. The volume and pace of change has been such that few have had time to digest it: not least policymakers, with the consequence that the developments have not always been well coordinated. The recent financial crisis has yet again thrown many – quite fundamental – issues into question. In this article, we offer an overview that puts the most significant developments of this decade into context, alongside each other and the changing patterns of corporate structure in European countries. Such developments cover, for instance, corporate mobility, corporate freedom of establishment, golden shares case law, as well as the Commission’s Company Law Action Plan CLAP and Financial Services Action Plan FSAP. Harmonization of Member States’ company laws on the rules governing listed companies and the facilitation of cross-border restructuring are also examined.

J Armour, BS Black and BR Cheffins, 'Is Delaware Losing its Cases?' (2012) 9 Journal of Empirical Legal Studies 605 [...]

Delaware’s expert courts are seen as an integral part of the state’s success in attracting incorporation by public companies. However, the benefit that Delaware companies derive from this expertise depends on whether corporate lawsuits against Delaware companies are brought before the Delaware courts. We report evidence that these suits are increasingly brought outside Delaware. We investigate changes in where suits are brought using four hand-collected data sets capturing different types of suits: class action lawsuits filed in (1) large M&A and (2) leveraged buyout transactions over 1994–2010; (3) derivative suits alleging option backdating; and (4) cases against public company directors that generate one or more publicly available opinions between 1995 and 2009. We find a secular increase in litigation rates for all companies in large M&A transactions and for Delaware companies in LBO transactions. We also see trends toward (1) suits being filed outside Delaware in both large M&A and LBO transactions and in cases generating opinions; and (2) suits being filed both in Delaware and elsewhere in large M&A transactions. Overall, Delaware courts are losing market share in lawsuits, and Delaware companies are gaining lawsuits, often filed elsewhere. We find some evidence that the timing of specific Delaware court decisions that affect plaintiffs’ firms coincides with the movement of cases out of Delaware. Our evidence suggests that serious as well as nuisance cases are leaving Delaware. The trends we report potentially present a challenge to Delaware’s competitiveness in the market for incorporations.

J Armour and P Lele, 'Law, Finance and Politics: The Case of India' (2009) 43 Law and Society Review 491 [...]

DOI: 10.1111/j.1540-5893.2009.00380.x

The process of liberalisation of India's economy since 1991 has brought with it considerable development both of its financial markets and the legal institutions which support these. An influential body of recent economic work asserts that a country's 'legal origin'-as a civilian or common law jurisdiction-plays an important part in determining the development of its investor protection regulations, and consequently its financial development. An alternative theory claims that the determinants of investor protection are political, rather than legal. We use the case of India to test these theories. We find little support for the idea that India's legal heritage as a common law country has been influential in speeding the path of regulatory reforms and financial development. There is a complementarity between (i) India's relative success in services and software, (ii) the relative strength of its financial markets for outside equity, as opposed to outside debt, and (iii) the relative success of stock market regulation, as opposed to reforms of creditor rights. We conclude that political explanations have more traction in explaining the case of India than do theories based on 'legal origins'.
