We analyze the existence of price manipulation and optimal trade execution strategies in a model for an electronic limit order book with nonlinear price impact and exponential resilience. Our main results show that, under general conditions on the shape function of the limit order book, placing...

The gravity equation in international trade is one of the most robust empirical finding in economics: bilateral trade between two countries is proportional to their respective sizes, measured by their GDP, and inversely proportional to the geographic distance between them. While the role of...

How does an economy behave if (1) fundamentals are truly hump-shaped, exhibiting momentum in the short run and partial mean reversion in the long run, and (2) agents do not know that fundamentals are hump-shaped and base their beliefs on parsimonious models that they fit to the available data? A...

This paper estimates the causal effect of attending an elite (or high performing) secondary school on student achievement using data from Kenyan secondary schools. The admission of students into government secondary schools in Kenya is centralized and is based solely on student scores on the...

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...
