This paper estimates the economic and non-economic returns to volunteering for prime-aged women. A woman's decision to engage in unpaid or paid work, and to marry and have children, is formulated as a discrete choice dynamic programming problem under uncertainty. Simulated maximum likelihood...

High Frequency Trading (HFT) improves investors' ability to seize trading opportunities, which raises gains from trade. It also enables fast traders to process information before slow traders, which generates adverse selection. We first analyze trading equilibria for a given level of HFT and then...

We derive a necessary condition, called the chain dominance property, for social choice correspondences to be admissibly implementable, i.e., given whatever admissible actions the agents play in each state, the outcomes always lie in the correspondence. The condition requires that the...

Performance rankings are a pervasive feature of life. Behavioral theories suggest that knowing one's rank may shape effort directly due to its effect on self-image. In a randomized control trial with full time employees (n=527) for whom rankings convey no Direct financial benefits, we study the...

We use administrative data from a major French e-commerce website to conduct an empirical analysis of the effect on posted prices of seller reputation, as measured by average buyer feedback. We derive a structural price equation which we take to transaction data for four separate categories of...

This paper identifies and estimates a hazard model in which the unobserved heterogeneity is modeled as a positive Levy stochastic process. The paper provides empirically relevant examples of such a model. Conditions for the identification of the parameters of interest and for the consistency of the...

Large retailers often compete with smaller stores carrying a narrower range. We find that large retailers can exercise market power by pricing below cost some of the products also offered by smaller rivals, in order to discriminate multi-stop shoppers from one-stop shoppers. Loss leading then...

We examine the empirical properties of the payoffs to two popular currency speculation strategies: the carry trade and momentum. We review three possible explanations for the apparent profitability of these strategies. The first is that speculators are being compensated for bearing risk. The second...
