Implications of Economic Interdependence for Endogenous Wage Indexation Decisions

This paper shows how economic interdependence affects the indexation decisions of atomistic wage setters in an environment in which monetary authorities do not observe stochastic disturbances before making their policy choices. If stochastic disturbances are common across countries, interdependence has no effect on equilibrium indexation choices in identical countries. However, if disturbances are country specific, numerical simulations show that interdependence is likely to reduce equilibrium indexation choices relative to a small open economy. We also show that indexation choices may be either strategic complements or strategic substitutes, but that strategic complementarity becomes more likely as the degree of interdependence rises.     

Adverse Selection and Pay Compression

A fundamental result of the principal-agent literature is that pay will be linked to performance when it is difficult for the principal to monitor the agent's actions. However, performance pay can lead to adverse incentives. In these models, high-powered incentives encourage workers to neglect some aspects of their job or to sabotage their coworkers' efforts. This paper offers another explanation for the weak link between pay and performance: worker heterogeneity. When workers are heterogeneous and labor contracts are contests, the Nash equilibrium often pools workers. I show that this implies that the link between pay and performance is weaker than would be the case if firms could observe workers' types before contracting and offer each type their respective optimal contests.     

Cow-calf profitability and leptin genotyping

Profitability of cow-calf production is determined largely by market prices, calf weaning weights, and cow productive life. While producers individually have no effect on prices, weaning weights and productive life have genetic influences and hence can be altered by selection programs implemented by producers. We investigate the impact of a mutation in the leptin gene (exon 2; single nucleotide polymorphism [SNP] 305) on cow-calf profitability. Prior research shows that this mutation has effects on performance and traits of fed cattle and milk production in dairy cows. Using data from a teaching-research herd, we find that it is also associated with calf weaning weights and cow productive life. A bio-economic stochastic simulation demonstrates that the mutation has statistically positive impacts on profits, suggesting that producers can profitably make use of this information.     

Business Ethics on the Internet: 2

In a previous article the authors provided an introduction to using the internet as a resource for business ethics. In this sequel they look at newsgroups and chatrooms, and conclude by looking at the websites of Shell and a Shell critic on the controversial ethical aspects of its corporate policy and behaviour.

African-oriented and Euro-American-oriented world views: Research methodologies and economics

Conclusion This paper has shown two things. First, it has indicated some of the philosophical ways in which a “pure” African-oriented world view differs in kind from the “pure” Euro-American-oriented one. Second, it has set forth some of their respective differences in research methodology, primarily focusing on the area of economics. However, neither of these world views and, therefore, their research methodologies have absolute validity. Each can claim validity only under its respective limiting conditions. In the words of Kuhn, “truth may, like proof, be a term with only intra-theoretic applications.” In effect, no interworld view comparison can or should be made in terms of absolute correspondence to reality. However, overseas Africans in America do embody both world views in varying degrees. Researchers on black people, therefore, must be familiar with both methodologies in order to analyze completely the behavior of Afro-Americans.     

Patent pools,litigation, and innovation

This article analyzes patent pools and their effects on litigation incentives, overall royalty rates, and social welfare when patent rights are probabilistic and can be invalidated in court. With probabilistic patents, the license fees reflect the strength of the patents. We show that patent pools of complementary patents can be used to discourage infringement by depriving potential licensees of the ability to selectively challenge patents and making them committed to a proposition of all‐or‐nothing in patent litigation. If patents are sufficiently weak, patent pools with complementary patents reduce social welfare as they charge higher licensing fees and chill subsequent innovation incentives.
