Disclosure by Politicians

Abstract: We collect data on the rules and practices of financial and conflict disclosure by politicians in 175 countries. Although two thirds of the countries have some disclosure laws, less than a third make disclosures available to the public. Disclosure is more extensive in richer and more democratic countries. Disclosure is correlated with lower perceived corruption when it is public, when it identifies sources of income and conflicts of interest, and when a country is a democracy.

The Benefits of Privatization: Evidence from Mexico

Abstract: Criticisms of privatization have centered around the possibility that the observed higher profitability of privatized companies comes at the expense of the rest of society. In this paper we focus on two of the most likely channels for social losses: (1) increased prices as firms capitalize on the market power; and (2) layoffs and lower wages as firms seek to roll back generous labor contracts. Using data for all 218 non-financial privatizations that took place in Mexico between 1983 and 1991 we find that privatized firms quickly bridge the pre-privatization performance gap with industry-matched control groups. For example, privatization is followed by a 24 percentage point increase in the ratio of operating income to sales. We roughly decompose those gains in profitability as follows: 10 percent of the increase is due to higher product prices; 33 percent of the increase represents a transfer from laid-off workers; and productivity gains account for the residual 57 percent. Transfers from society to the firm are partially offset by taxes which absorb slightly over half the gains in operating income. Finally, we also find evidence indicating that deregulation is associated with faster convergence to industry benchmarks.

Diagnostic Expectations and Stock Returns

Abstract: We revisit La Porta’s (1996) finding that returns on stocks with the most optimistic analyst long term earnings growth forecasts are substantially lower than those for stocks with the most pessimistic forecasts. We document that this finding still holds, and present several further facts about the joint dynamics of fundamentals, expectations, and returns for these portfolios. We explain these facts using a new model of belief formation based on a portable formalization of the representativeness heuristic. In this model, analysts forecast future fundamentals from the history of earnings growth, but they over-react to news by exaggerating the probability of states that have become objectively more likely. Intuitively, fast earnings growth predicts future Googles but not as many as analysts believe. We test predictions that distinguish this mechanism from both Bayesian learning and adaptive expectations, and find supportive evidence. A calibration of the model offers a satisfactory account of the key patterns in fundamentals, expectations, and returns.

What Moves the Discount on Country Equity Funds

Abstract: The paper characterizes several empirical regularities of closed- end fund prices and examines the extent to which a 'sentiment' model of asset prices is consistent with the empirical regularities. We find that after controlling for the effect of cross-border investment restrictions, country funds trade at an average discount. Discounts vary substantially and contribute to a variance in country fund weekly returns which is generally three times greater than the returns on the net asset value (NAV). Regression analysis suggests that discounts have predictive power for fund returns but not for NAV returns, suggesting that investor 'sentiment' is a component of the price of a fund and not its NAV. Estimation of an unobserved components model on the discounts of the funds reveals a significant and strongly persistent common component across fund discounts. Regressions of fund and NAV returns on financial variables reveal that fund prices are 'sticky' with respect to movements in the host country's stock market and overly sensitive to variation in the U.S. and world stock markets. This relation is unaffected when we consider separately funds whose host countries restrict cross-border investment and funds which invest in emerging stock markets.

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.

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 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.

Legal Determinants of External Finance

Abstract: Using a sample of 49 countries, we show that countries with poorer investor protections, measured by both the character of legal rules and the quality of law enforcement, have smaller and narrower capital markets. These findings apply to both equity and debt markets. In particular, French civil law countries have both the weakest investor protections and the least developed capital markets, especially as compared to common law countries.

Corporate Ownership Around the World

Abstract: We use data on ownership structures of large corporations in 27 wealthy economies to identify the ultimate controlling shareholders of these firms. We find that, except in economies with very good shareholder protection, relatively few of these firms are widely held, in contrast to Berle and Means’s image of ownership of the modern corporation. Rather, these firms are typically controlled by families or the State. Equity control by financial institutions is far less common. The controlling shareholders typically have power over firms significantly in excess of their cash f low rights, primarily through the use of pyramids and participation in management.
