The evolution of common law

Abstract: We present a model of lawmaking by appellate courts in which judges influenced by policy preferences can distinguish precedents at some cost. We find a cost and a benefit of diversity of judicial views. Policy‐motivated judges distort the law away from efficiency, but diversity of judicial views also fosters legal evolution and increases the law’s precision. We call our central finding the Cardozo theorem: even when judges are motivated by personal agendas, legal evolution is, on average, beneficial because it washes out judicial biases and renders the law more precise. Our paper provides a theoretical foundation for the evolutionary adaptability of common law.

Investor Sentiment and the Closed-End Fund Puzzle

Abstract: This paper examines the proposition that fluctuations in discounts on closed end funds are driven by changes in individual investor sentiment toward closed end funds and other securities. The theory implies that discounts on various funds must move together, that new funds get started when seasoned funds sell at a premium or a small discount, and that discounts on the funds fluctuate together with prices of securities affected by the same investor sentiment. The evidence supports these predictions. In particular, we find that discounts on closed end funds narrow when small stocks do well, as would be expected if closed end funds were subject to the same sentiment as small stocks, whim tern. also to be held by individual investors. The evidence thus suggests that investor sentiment affects security returns.

Diagnostic Expectations and Credit Cycles

Abstract: We present a model of credit cycles arising from diagnostic expectations – a belief formation mechanism based on Kahneman and Tversky’s (1972) representativeness heuristic. In this formulation, when forming their beliefs agents overweight future outcomes that have become more likely in light of incoming data. The model reconciles extrapolation and neglect of risk in a unified framework. Diagnostic expectations are forward looking, and as such are immune to the Lucas critique and nest rational expectations as a special case. In our model of credit cycles, credit spreads are excessively volatile, over-react to news, and are subject to predictable reversals. These dynamics can account for several features of credit cycles and macroeconomic volatility.

Law and Finance

Abstract: This paper examines legal rules covering protection of corporate shareholders and creditors, the origin of these rules, and the quality of their enforcement in 49 countries. The results show that common law countries generally have the best, and French civil law countries the worst, legal protections of investors, with German and Scandinavian civil law countries located in the middle. We also find that concentration of ownership of shares in the largest public companies is negatively related to investor protections, consistent with the hypothesis that small, diversified shareholders are unlikely to be important in countries that fail to protect their rights.

Abstract: This paper examines legal rules covering protection of corporate shareholders and creditors, the origin of these rules, and the quality of their enforcement in 49 countries. The results show that common-law countries generally have the strongest, and Frenchcivil-law countries the weakest, legal protections of investors, with German- and Scandinavian-civil-law countries located in the middle. We also find that concentration of ownership of shares in the largest public companies is negatively related to investor protections, consistent with the hypothesis that small, diversified shareholders are unlikely to be important in countries that fail to protect their rights.

A Survey of Corporate Governance

Abstract: 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

Returns to Buying Winners and Selling Losers: Implications for Stock Market Efficiency

Abstract: This paper documents that strategies which buy stocks that have performed well in the past and sell stocks that have performed poorly in the past generate significant positive returns over 3- to 12-month holding periods. We find that the profitability of these strategies are not due to their systematic risk or to delayed stock price reactions to common factors. However, part of the abnormal returns generated in the first year after portfolio formation dissipates in the following two years. A similar pattern of returns around the earnings announcements of past winners and losers is also documented
