We construct a model of firm dynamics with heterogeneous productivity and distortions. The productivity distribution evolves endogenously as the result of the decisions of firms seeking to upgrade their productivity over time. Firms can adopt two strategies toward that end: imitation and...

This study examines the determinants of exit from academic research which occurs when academic researchers move into positions in academe which concentrate on non-research activities such as teaching or administration, or when researchers leave academia and move into industry. Drawing on career...

We construct an endogenous growth model with random interactions where firms are subject to distortions. The TFP distribution evolves endogenously as firms seek to upgrade their technology over time either by innovating or by imitating other firms. We use the model to quantify the effects of...
