In this talk we consider estimation of linear models with many regressors, possibly much more than the sample size and endogenous regressors. We propose a method based on instrumental variables. It is pivotal in the sense that it does not require the knowledge of the variance of the errors. It does...

Fitness maximisation is a theoretically controversial but empirically much used deduction about natural selection. In the presence of environmental and demographic uncertainty, current popula- tion models suggest that selection does not simply maximise mean fitness, but also reduces the variance....

Humans’ ability to collaborate to obtain otherwise inaccessible goals may be one main reason of our success as a species. For mutually beneficial collaboration, individuals need (1) cognitive mechanisms to coordinate actions with partners, and (2) mechanisms to distribute the acquired resources in...

This paper investigates the determinants of college attrition in a setting where individuals have imperfect information about their schooling ability and labor market productivity. We estimate, a dynamic structural model of schooling and work decisions, where high school graduates choose a bundle...

Using data from New York and Pennsylvania and an array of empirical techniques to control for confounding factors, we recover hedonic estimates of property value impacts from shale gas development that vary with geographic scale and water source. Results indicate large negative impacts on nearby...

Favoritism prevails in organizations that rely on subjective assessments of employee performance, and its harmful impact on the efficiency is widely recognized. This paper shows that favoritism could benefit the employer when collusion among employees becomes a serious threat in organizations....

We present a simple macroeconomic model in which the real prices of commodities have a factor structure. In the model, a continuum of commodities is used in the production of the final good, and the real price of each commodity is endogenously determined. One factor captures the combined...

This paper studies design of a recommender system for organizing social learning on a product. The optimal design trades off fully transparent social learning to improve incentives for early experimentation, by selectively over-recommending a product in the early phase of the product release. Under...
