The anomaly is concerned with the observation that in multiple item auctions of identical objects, prices tend to decline over time. I show that in the case of wine auctions, which have been analyzed frequently, the anomaly is likely to be caused by the fact that most bids are entered by absentees, who use nonoptimal bidding strategies. Therefore, wine auctions can hardly be used to illustrate the standard multiple‐object auction model.

This paper brings together methodological, theoretical, and empirical analysis into the framework of linguistic diversity. It reflects both historical and contemporary research by economists and other social scientists on the impact of language on economic outcomes and public policies. We examine whether and how language influences human thinking (including emotions) and behavior, and analyze the effects of linguistic distances on trade, migrations, financial markets, language learning, and its returns. The quantitative foundations of linguistic diversity, which rely on group identification, linguistic distances as well as fractionalization, polarization, and disenfranchisement indices are discussed in terms of their empirical challenges and uses. We conclude with an analysis of linguistic policies and examine the trade-offs between the development of labor markets and the social costs that they generate in various countries.

Members of a rock and roll band are endowed with different amounts of creativity. They match, compose songs, and share credit. The presence of more creative members increases the probability of success, but those more creative members may also claim a larger share of the pie. In our theoretical model, the nature of matching as well as the covariation between the probability of success and the allocation of credit among individual members are a function of the completeness of contracting. The data show that rock bands tend to enter into incomplete contracts and positive assortative matching.
