Economics of compatibility standards and competition in telecommunication networks

The pro- and anti-competitive implications of technical compatibility standards are introduced in general terms and then applied to current issues in telecommunications policy. The demand and supply for standards under regulated monopoly and the transition to deregulation and competitive entry create a tradeoff between the traditional goal of achieving positive externalities from interconnection and the alternative goal of providing enhanced service offerings that may involve sacrificing universal connectivity. We argue that this tradeoff has affected the utilization of data communication networks in the U.S. and Europe. In addition, we identify problems of competing interests that complicate the European approach to standards “harmonization” in the case of telecommunications. We conclude by noting that the nature of standards and standard-setting process can have marked effects on the incentives to conduct private research and development.     

Teaching foreign currency translation: A flowchart approach

This paper briefly discusses the major aspects of FASB Statement No. 52 and presents a flowchart designed to assist accounting instructors in teaching the accounting and reporting requirements for foreign currency translations.     

Systematic Risk and Diversification in the Equity REIT Market

This paper employs stock market-based data to examine the systematic risk and diversification properties of publicly traded equity real estate investment trusts (REITs). A unique data sample is created by combining firm return data with information on their property type holdings and the location of their investments. The systematic risk of equity REITs appears to vary by the type of property in which they invest, with beta being significantly higher for retail-oriented REITs than for REITs owning industrial and warehouse properties. In addition, the stock market data provides no evidence that REIT diversification across property types or broad geographic regions actually results in meaningful diversification as reflected in a standard market-based measure—the R ² from a simple market model regression.     

A Reconsideration of the Rationality Postulate: 'Right Hemisphere Thinking' in Economics

A bstract . The cardinal postulate of neoclassical economics is that individuals and entrepreneurs seek to maximize their unique positions in the world. Yet behind this postulate is an even more fundamental premise: that men are rational and can discern their own best interests. From Adam Smith on, it has been accepted that reasonable men act to maximize their own pecuniary advantage and in most economic models even the potential for irrationality is ignored. Nevertheless, it is becoming increasingly obvious from the research conclusions of other disciplines ( psychology, philosophy, political science, and sociology in particular) that the simplistic notion of " economic man ," posited so often in the economics literature, is more fancy than fact. There is an implicit recognition that the neoclassical assumptions may not be correct in the developing area of economic behaviorism. The economic behaviorists, however, adopt a more general definition of rationality, substituting what might be called a "modified rationality postulate" for the global rationality assumed in neoclassical theory. As a result, their conclusions do not differ greatly from those of the neoclassicists. Fortunately, ideas are now crystallizing in psychology which may enable us to shed light on decisions which previously would have had to be classified as non-rational, irrational, or unexplainable. Some of those ideas are explored.     

Competitive price adjustment

A study is made of a competitive trading process in which a price-maker calls prices periodically under the obligation of trading for his own account to satisfy excess demand. Characteristics of the price-maker's optimal behavior are derived. The price-maker system is evaluated with respect to an alternative market clearing system.     

CONDITIONAL HETEROSCEDASTICITY IN THE MARKET MODEL AND EFFICIENT ESTIMATES OF BETAS

Previous studies have investigated only unconditional heteroscedasticity in the market model. This paper tests for both conditional and unconditional heteroscedasticities as well as normality. Using the monthly stock rate of return data secured from the Center for Research in Security Prices (CRSP) tape for 1976 through 1983, this paper shows that conditional heteroscedasticity is more widespread than unconditional heteroscedasticity, suggesting the necessity of model refinements that take conditional heteroscedasticity into account. This paper provides an alternative estimation of betas of individual securities and portfolios based on the autoregressive conditional heteroscedastic (ARCH) model introduced by Engle. The efficiency of the market model coefficients is markedly improved across all firms in the sample through the ARCH technique.
