Goods Prices and Exchange Rates: What Have We Learned?

Abstract: Import prices typically change by a smaller proportion than the exchange rate between the exporting and importing country. Recent research indicates that common-currency relative prices for similar goods exported to different markets are highly correlated with exchange rates between those markets. This evidence suggests that incomplete pass-through is a consequence of third-degree price discrimination. While distance matters for market segmentation, borders have independent effects. The source of the border effect has not been clearly identified. Furthermore, there is little evidence yet to suggest substantial market power is implied by the observed price discrimination.

D1 Dopamine Receptors in Prefrontal Cortex: Involvement in Working Memory

Abstract: The prefrontal cortex is involved in the cognitive process of working memory. Local injections of SCH23390 and SCH39166, selective antagonists of the D1 dopamine receptor, into the prefrontal cortex of rhesus monkeys induced errors and increased latency in performance on an oculomotor task that required memory-guided saccades. The deficit was dose-dependent and sensitive to the duration of the delay period. These D1 antagonists had no effect on performance in a control task requiring visually guided saccades, indicating that sensory and motor functions were unaltered. Thus, D1 dopamine receptors play a selective role in the mnemonic, predictive functions of the primate prefrontal cortex.

Preferences in human mate selection.

Abstract: In this article we examine preferences in mate choice within the broader context of the human mating system. Specifically, we discuss the consequences of mate preferences for the processes of assortative mating and sexual selection. In Study 1 (N = 184) we document (a) the mate characteristics that are consensually more and less desired, (b) the mate characteristics that show strong sex differences in their preferred value, (c) the degree to which married couples are correlated in selection preferences, and (d) the relations between expressed preferences and the personality and background characteristics of obtained spouses. In Study 2 (N = 100) we replicated the sex differences and consensual ordering of mate preferences found in Study I, using a different methodology and a differently composed sample. Lastly, we present alternative hypotheses to account for the replicated sex differences in preferences for attractiveness and earning potential. Neither men nor women prefer all members of the opposite sex equally. Some are favored over others, and one important research task is to identify the characteristics that prospective mates consider to be important. Although mate choice is clearly a crucial adult decision for more than 90% of the population (Price & Vandenberg, 1980), surprisingly little is known about the characteristics that men and women seek in potential mates (Thiessen & Gregg, 1980). In this article we develop a conception of the role of mate preferences within the human mating system. Specifically, we address the consequences for sexual selection and assortative mating. In two empirical studies we document several basic features of this conception.

The polarizing impact of science literacy and numeracy on perceived climate change risks

Abstract: Public apathy over climate change is often attributed to a deficit in comprehension and to limits on technical reasoning. However, evidence suggests that individuals with the highest degrees of science literacy and technical reasoning capacity are not the most concerned about climate change and are the most culturally polarized.
