Smuggling and Bhagwati's Nonequivalence Between Tariffs and Quotas

The authors extend Professor Bhagwati's analysis about the nonequivalence between trade policy instruments when domestic production is monopolized and the terms of trade are endogenous, by allowing for smuggling. They show that the dominance of the ad valorem tariff over the quota is not robust. Tariffication can lower welfare even when the level of illegal imports is quite small. However, tariffication with a specific tariff is always beneficial because the specific tariff dominates the ad valorem tariff and the quota with or without smuggling. Smuggling (or the threat) also tends to lower the second–best tariff/quota, and increases welfare when imports are restricted by a quota, but lowers it under a tariff.     

THE ASSOCIATION BETWEEN EXECUTIVE SUCCESSION AND DISCRETIONARY ACCOUNTING CHANGES: EARNINGS MANAGEMENT OR DIFFERENT PERSPECTIVES?

This paper investigates the association of executive changes with both income increasing and decreasing accounting changes. Two potential explanations for the hypothesis that firms with changes in CEOs are more likely to make accounting changes are examined. The earnings management explanation holds that new management intervenes in the financial reporting process in order to alter perceptions of effectiveness. The different perspectives explanation holds that managements have different tastes, perspectives, or views of the world than the predecessor. Evidence supports the different perspectives explanation.     

Ex Ante Stock Market Return Volatility Implied by the OEX Option Premium

Previous empirical evidence suggests that stock return volatility expectations change over time, but the existing models of time-varying variance lack a theoretical structure that is rigorously linked to the efficient markets dividend discount model. This paper develops and tests such a model. The conditional forecast variance of the return on the stock market portfolio is expressed as a linear combination of the adjusted conditional forecast variance of the interest rate and the dividend growth rate. An empirical test using the implied variance of the S&P 100 index option provides evidence that supports the model's predictions.     

Privatisation: Let the Market Decide

Is the Government privatising efficiently? Is it floating the shares in nationalised industry economically? Will British Telecom be under-priced? Professor Davis and Roger Buckland have studied the privatisation issues of shares over five years and found large but avoidable losses. They argue that the Government's marketing technique could be improved by making less use of the large financial institutions and more use of competitive tenders.     

THE RELATIONSHIP BETWEEN FINANCIAL PERFORMANCE AND STOCK MARKET BASED MEASURES OF CORPORATE DIVERSIFICATION

This study examines the relationship between corporate diversification and financial performance. The use of a stock market based measure of diversification allowed a much larger database than in previous studies and overcame the subjective nature of measuring internal diversification. Because previous researchers found that firm size affected performance, size was controlled in this analysis. The authors conclude that there is no statistically significant relationship between the degree of internal diversification and financial performance.
