PROTECTION OF INTELLECTUAL PROPERTY RIGHTS: RESEARCH AND DEVELOPMENT DECISIONS AND ECONOMIC GROWTH

Determining the appropriate degree of protection to provide intellectual property in the United States and abroad is an important public policy issue. This paper addresses the role of intellectual property protection in the firm's decision on the level of investment in research and development. It also focuses on the stimulus that such protection provides for economic growth in both developed and developing countries. The main conclusion is that the benefits of designing and enforcing a mechanism for strong protection of intellectual property generally exceed the costs.     

Nonsynchronous Security Trading and Market Index Autocorrelation

The theoretical portfolio autocorrelation due solely to nonsynchronous trading is estimated from a derived model. This estimated level is found to be substantially less than that observed empirically. The theoretical and empirical relationship between portfolio size and autocorrelation also is investigated. The results of this study suggest that other price-adjustment delay factors in addition to nonsynchronous trading cause the high autocorrelations present in daily returns on stock index portfolios.     

Institutions and Individuals at the Turn-of-the-Year

This article evaluates the tax-loss-selling hypothesis against the window-dressing hypothesis as explanations for turn-of-the-year anomalies. We examine differences between securities dominated by individual investors versus those dominated by institutional investors and find that the effect is more pervasive in the former. Controlling for capitalization, we find that in early January (late December), stocks with greater individual investor interest outperform (underperform) stocks with greater institutional investor interest. These results hold for both stocks that previously appreciated in value and stocks that previously depreciated in value. The results are most consistent with the tax-loss-selling hypothesis as an explanation for the turn-of-the-year effect.     

Industrial Structure and the Comparative Behavior of International Stock Market Indices

Stock Price Indices are compared across countries in an attempt to explain why they exhibit such disparate behavior. Three separate explanatory influences are empirically documented. First, part of the behavior can be attributed to a technical aspect of index construction; some indices are more diversified than others. Second, each country's industrial structure plays a major role in explaining stock price behavior. Third, for the majority of countries, a portion of national equity index behavior can be ascribed to exchange rate behavior. Exchange rates explain a significant portion of common currency denominated national index returns, although the amount explained by exchange rates is less than the amount explained by industrial structure for most countries.     

Testing Rationality in the Point Spread Betting Market

This paper presents empirical tests of market rationality using data from the point spread betting market on National Football League games. Data from this market avoid many common pitfalls of tests of rationality in conventional financial markets. The authors test for rationality with two types of tests, statistical and economic. Results of the tests reveal that the statistical tests cannot reject market rationality while the economic tests do reject market rationality.     

Inflation and Stock Market Returns:Some Australian Evidence*

This paper analyzes the relationship between Australian stock returns and inflation over the period 1965-79. The effects of inflation in a ‘rational investor’ valuation framework are discussed. Empirical tests suggest that nominal stock returns and inflation are related in a significantly negative fashion, implying that stocks have been extremely poor inflationary hedges for the investor over the period. In addition, Granger-Sims tests of causality indicate a mainly unidirectional relationship between inflation and stock returns, with price level charges leading the equity index in time.     

Industrial Relations in Western Europe: An Era of Ambiguity?

In western Europe, as in the United States, the 1980s saw major challenges to established institutions of industrial relations. Managements, faced with intensified competitive pressure, have taken the initiative; union have been on the defensive. Deregulation and decentralization have been the recurrent themes of both practitioners and academic analysts. For some commentators, national distinctiveness is giving way to convergence, encouraged in part by moves toward the Single European Market. This article develops a more skeptical perspective on recent trends.
