Information,Pricing and Efficiency in Cash and Futures Markets: The Case of Hogs

The price leadership roles among hog cash and futures markets are assessed to locate points of price discovery and to examine flows of information among these markets. Several years of data are analyzed using lead/lag causality analysis and strength of linear causality measures. Although significant instantaneous relationships exist among hog cash and futures markets, one-way causality tests indicate that generally the futures market dominates cash hog markets in the price discovery process.     

Earnings and Percentage Female: A Longitudinal Study

Comparable worth advocates assume that the relation between earnings and percentage female in an occupation is due to crowding or other forms of discrimination. An alternative explanation is that the relation stems from women freely choosing different occupations. Using longitudinal data to control for time-invariant omitted variables, as well as cross-sectional data (for comparison with previous research), we find that although men's estimated penalty is not reduced, the percentage female penalty falls substantially for women and is not statistically significant. These results imply that estimates of the percentage female effect based on cross-sectional data may be inflated for women–except for those with intermittent labor force participation. This group does experience a sizeable penalty for working in female-dominated occupations. Hence, a comparable worth policy would most likely benefit women with discontinuous employment.     

Return Dynamics of Japanese Stock Index Options

This paper addresses the return dynamics of stock index options. Distributional moments are suggestive of a skewness preference hypothesis that provides an economic rationale for investors' interest in options. There is no evidence of detectable intermarket arbitrage opportunities from cross- sectional tests of volatility ratio and implied elasticity. Joint tests of market efficiency and parity dynamics suggest that the longer the remaining life of at-the-money options, the higher the likelihood of parity deviations being absorbed in response to percentage index changes. There are also indications of maturing Japanese options markets from rational expectations and parity regression tests.     

Cultural Relevance of Western Accounting Systems to Developing Countries

It has been suggested recently that the accounting systems used in developing countries may be irrelevant to their needs because they originate in Western countries with different cultural values. The accounting literature on this point, however, is vague in its assessment of exactly what aspects of Western accounting systems fail to meet the test of relevance. Furthermore, it is not clear whether the differences between the needs of users in various countries are differences in kind or only differences in degree. This article analyses these issues by introducing technical considerations in addition to the behavioural ones usually discussed and by separating out problems of accounting measurement from problems of accounting disclosure. This distinction is used to argue that it is the specific disclosure rules of particular calculations inherent in Western accounting systems rather than the transaction cost database that are most likely to fail to satisfy the needs of users in developing countries. The effect of the importation of the French Unified Accounting System to Lebanon is examined and an amended version of the Hofstede-Gray cultural accounting framework is used to clarify the concept of cultural relevance.
