In this paper, I study the welfare properties of growth models with endogenous innovation, knowledge externalities, and monopoly pricing of new goods. Since useful policy prescriptions cannot be inferred from a balanced growth analysis, welfare is analyzed for transition paths. I provide a...

In this paper we are interested in inference based on heteroskedasticity consistent covariance matrix estimators, for which the appropriate bootstrap is a version of the wild bootstrap. Simulation results, obtained by a new very efficient method, show that all wild bootstrap tests exhibit...
