Laboratory experiments on the provision of public goods follow subjects over time as they interact in a small group. In every period subjects allocate a fixed endowment between a private good and a group good that yields a return to all group members. These experiments produce data sets that are...

We establish that the Phillips curve is persistence-dependent: inflation responds differently to persistent versus moderately persistent (or versus transient) fluctuations in the unemployment gap. Previous work fails to model this dependence, so it finds numerous “inflation puzzles”—such...

This work describes a versatile and readily-deployable sensitivity analysis of an ordinary least squares (OLS) inference with respect to possible endogeneity in the explanatory variables of the usual k-variate linear multiple regression model. This sensitivity analysis is based on a derivation...
