Union Carbide's chemical leak in Bhopal, India during December 1984 resulted in approximately 4,000 deaths and 200,000 injuries. This study examines the market reaction of chemical firms other than Union Carbide to this catastrophe. Evidence indicates that a significant negative intra-industry reaction occurred. However, firms with more extensive environmental disclosures in their financial report prior to the chemical leak experienced a less negative reaction than firms with less extensive disclosures. This result suggests that investors interpreted such disclosures as a positive sign of the firm managing its exposure to future regulatory costs.

This paper tests the demand-side prediction of Datar, Feltham, and Hughes (1991) that new issuers of securities are more likely to choose a high-quality auditor and retain a lower level of ownership as the firm-specific riskiness of future cash flows increases. Previous tests of this hypothesis using U.S. data have generally been inconclusive, perhaps because an increase in the riskiness of client cash flows simultaneously increases an auditor's litigation risk and supply price. Our results using data from a significantly different legal environment (Canada) are consistent with the predictions of Datar, Feltham, and Hughes.

The objective of the Institute for Policy Reform is to enhance the foundation for broad based economic growth in developing countries.Through its research, education and training activities the Institute encourages active participation in the dialogue on policy reform, focusing on changes that stimulate and sustain economic development.At the core of these activities is the search for creative ideas that can be used to design constitutional, institutional and policy reforms.Research fellows and policy practitioners are engaged by IPR to expand the analytical core of the reform process.This includes all elements of comprehensive and customized reforms packages, recognizing cultural, political, economic and environmental elements as crucial dimensions of societies.

Increases in import competition led to large increases in labor productivity growth in highly concentrated industries during the period from 1975 through 1987. The finding is based on a panel of ninety-four manufacturing industries observed over four periods, each of three years duration. Imports had no observable effects on productivity growth in less concentrated industries; the strong effects in concentrated industries did not occur contemporaneously but appeared with a one-period lag. The effects are weakened but still statistically significant when Bureau of Labor Statistics productivity data are replaced by National Bureau of Economic Research data and in a larger panel with less precise trade data.

The effect of changing prices on the supply of physicians' services has important policy implications. In this note, a correction of previous work on supply by the author in this shows that with aggregate data the price elasticity of supply is zero. However, using individual physician data in the context of a utility-maximizing model of supply, it is found that the price elasticity of supply is about -0.2. This result could portend serious problems ahead for recently enacted Medicare pricing strategies to contain physician spending.

Immigrants' ties to their home countries can play a key role in fostering bilateral trade linkages. Immigrant ties include knowledge of home-country markets, language, preferences, and business contacts that have the potential to decrease trading transaction costs. Empirical results for the United States suggest that immigrant links have historically been important in increasing bilateral trade flows with immigrants' home countries.

Sunk cost models of new trade theory have demonstrated that large, unanticipated swings in currency values can have permanent effects on trade flows by altering market structure in imperfectly competitive markets. The author tests an implication of these models using panel data on export unit values from Germany and Japan to a number of foreign markets, including the United States. He finds weak evidence in support of the thesis that U.S. product markets became more competitive as a result of the large dollar appreciation of the 1980s, although the results vary by industry and comparison country.

We consider the multiperiod relationship between a client and a portfolio manager and the resulting problem of motivating a manager of unknown ability to acquire valuable information. We explore the contractual forms and the optimal retention policy of the client and find that the optimal initial set of contracts features a smaller performance-based fee component paid to the manager than in a first-best contract, and the contract choice elicits only partial information about the manager. As a result, ex post performance measurement is critical to future recontracting. In general, managers are retained only if the returns on their portfolio exceed the benchmark by an appropriate amount.

This paper derives observable properties of economies with optimal income distribution rules that specify consumers' incomes as functions of aggregate income and prices. Optimality implies that the aggregate demand function is generated by a single “representative” consumer, cf. Samuelson (1956). We derive an additional implication which, when consumers receive fixed shares of aggregate income, requires that the consumers' demands become more dispersed when aggregate income rises. This last condition has empirical support. The results relate the representative consumer's preferences to a version of Kaldor's compensation criterion and show when both can be used for normative analysis without internal inconsistency.
