We investigate one of the world’s most pernicious forms of exploitation: child soldiering. Most theories can be captured by a principal-agent model that incorporates punishments, indoctrination, and age-varying productivity. For rebel leaders, we show it is almost always optimal to coerce rather...

This paper studies the real estate brokerage industry in Greater Boston using a panel data set that covers 257,923 properties and 10088 brokers from 1999 to 2007. We establish several stylized facts regarding entry and exit among real estate agents. First, more than 12% of active real estate agents...

Random forests are a scheme proposed by Leo Breiman in the 00's for building a predictor ensemble with a set of decision trees that grow in randomly selected subspaces of data. Despite a growing interest and emphasis on practice guidelines, there has been few explorations of the statistical...

We examine the effect of the Amnesty Plus policy on the incentives of firms to engage in cartel activities. Amnesty Plus is aimed at attracting leniency applications by encouraging firms, convicted in one market, to report their collusive agreements in other markets. It has been vigorously...

Flexible labor markets require geographically mobile workers to be efficient. Otherwise, firms can take advantage of the immobility of workers and extract monopsony rents. In cultures with strong family ties, moving away from home is costly. Thus, individuals with strong family ties rationally...

We analyze a general equilibrium labor market model where moral hazard problems are a key concern. We show that variation in moral hazard across types of jobs explains contract terms, work patterns over time, and promotion structures. We explain why high-profile jobs such as investment banking pay...

L'inégalité de Lojasiewicz et ses diverses généralisations sont centrales dans l'analyse asymptotique des systèmes de type gradient (optimisation, complexité, équations aux dérivées partielles) et constituent une des motivations fortes de cette étude. Le but de cette dernière est double. Il...

A committee decides by unanimity whether to accept the current alternative, or to continue costly search. Each alternative is described by a vector of distinct attributes, and each committee member can privately assess the quality of one attribute (her "speciality"). Preferences are heterogeneous...

Linear cointegration is known to have the important property of invariance under temporal translation. The same property is shown not to apply for nonlinear cointegration. The requisite limit theory involves sample covariances of integrable transformations of non-stationary sequences and time...
