A Survey of Corporate Governance

This article surveys research on corporate governance, with special attention to the importance of legal protection of investors and of ownership concentration in corporate governance systems around the world. CORPORATE GOVERNANCE DEALS WITH the ways in which suppliers of finance to corporations assure themselves of getting a return on their investment. How do the suppliers of finance get managers to return some of the profits to them? How do they make sure that managers do not steal the capital they supply or invest it in bad projects? How do suppliers of finance control managers? At first glance, it is not entirely obvious why the suppliers of capital get anything back. After all, they part with their money, and have little to contribute to the enterprise afterward. The professional managers or entrepreneurs who run the firms might as well abscond with the money. Although they sometimes do, usually they do not. Most advanced market economies have solved the problem of corporate governance at least reasonably well, in that they have assured the flows of enormous amounts of capital to firms, and actual repatriation of profits to the providers of finance. But this does not imply that they have solved the corporate governance problem perfectly, or that the corporate governance mechanisms cannot be improved. In fact, the subject of corporate governance is of enormous practical impor

A Course in Game Theory presents the main ideas of game theory at a level suitable for graduate students and advanced undergraduates, emphasizing the theory's foundations and interpretations of its basic concepts. The authors provide precise definitions and full proofs of results, sacrificing generalities and limiting the scope of the material in order to do so. The text is organized in four parts: strategic games, extensive games with perfect information, extensive games with imperfect information, and coalitional games. It includes over 100 exercises.

Does finance affect economic growth? A number of studies have identified a positive correlation between the level of development of a country's financial sector and the rate of growth of its per capita income. As has been noted elsewhere, the observed correlation does not necessarily imply a causal relationship. This paper examines whether financial development facilitates economic growth by scrutinizing one rationale for such a relationship; that financial development reduces the costs of external finance to firms. Specifically, we ask whether industrial sectors that are relatively more in need of external finance develop disproportionately faster in countries with more developed financial markets. We find this to be true in a large sample of countries over the 1980s. We show this result is unlikely to be driven by omitted variables, outliers, or reverse causality.

A Theory of Dynamic Oligopoly, III: Cournot Competition

As illustrated by liquidity support, equity injections and asset repurchases in financial crises and by IMF credit lines to countries, authorities often intervene in orderto revive markets that have dried up or to create newones. In suchsituations, agents participate only if they receive from the governmental scheme more than in the marketplace, while the market outcome depends on who joins the scheme. The paper provides a first analysis of market jumpstarting and its two-way interaction between mechanism design and participation constraints. In the model, sellers in need of cash have private information about the value of their legacy asset. The absence of buyer confidence forces authorities to intervene to jump-start the market. We characterize the optimal intervention, and draw two main implications. First, the government should clean up the market, through buybacks of the weakest assets and then through some equity injections, and leave the agents with the strongest legacy assets to the market. In particular, authorities should not substitute fully for the market, even when they have no comparative disadvantage in acquiring assets or shares thereof. Second, the government creates its own competition by cleaning up the market from its most toxic pieces. At the optimal intervention the government always strictly overpays for the legacy asset. Yet, and unlike what would be suggested by Coasian profit evasion, the existence of a later market imposes no welfare cost. While it is cast in a public intervention context, the analysis of mechanismdependent reservation utilities also admits important private sector applications.

Capital as a commitment: Strategic investment to deter mobility

The paper develops a theory of costly communication in which the sender's and receiver's motivations and abilities endogenously determine the communication mode and the transfer of knowledge. Communication is modeled as a problem of moral hazard in teams, in which the sender and receiver select persuasion and message elaboration efforts. The model is shown to provide a rich set of insights concerning (i) the impact of incentive alignment on communication strategies, (ii) the relative influence and the complementarity/substitutability between issue-relevant communication and cues (information that relates to the credibility of the sender rather than to the issue at stake), and (iii) the path dependency of communication.

The recent unravelling of the Eurozone’s financial integration raised concerns about feedback loops between sovereign and banking insolvency, and provided an impetus for the European banking union. This paper provides a “double-decker bailout” theory of the feedback loop that allows for both domestic bailouts of the banking system by the domestic government and sovereign debt forgiveness by international creditors or solidarity by other countries. Our theory has important implications for the re-nationalization of sovereign debt, macroprudential regulation, and the rationale for banking unions.
