摘要：Before the opening of the Paris Bourse, traders place orders and indicative prices are set. This offers a laboratory to study empirically the tatonnement process through which markets discover equilibrium prices. Since preopening orders can be revised or canceled before the opening, indicative prices could be noise. We test this against the hypothesis that preopening prices reflect learning. Early in the preopening the noise hypothesis is not rejected. As the opening gets closer, the informati...

摘要：Preference for sons over daughters is widespread in many Asian countries, for example, India, China, and South Korea. This paper models endogenous sex choice and shows that unbalanced sex ratios are but one of several possible consequences of a preference for sons. In particular, if parents want children who reproduce, nonrandom mating may cause women to be consistently born into low-status families and thus relegated to a permanent underclass. The paper also discusses possible links between s...

Higher pecuniary benefits for crime in large cities can explain at most one-quarter of the connection between city size and crime rates. Lower probabilities of arrest and a lower probability of recognition are features of urban life, but these factors seem to explain at ...

摘要：Price and quantity data prove that Irish potatoes in the 1840s were not Giffen goods. Intertemporal trade-offs required by the fact that a sizable fraction of the potato crop is needed for seed crops can produce unusual market dynamics. The Irish experience is well described by a normal demand model in which a permanent decline in the productivity of seed potatoes was at first mistaken as a transitory crop failure. These mistakes provoked oversaving of seed crop in a population in dire circums...
