What factors underlie industry differences in research intensity and productivity growth? We develop a multi-sector endogenous growth model allowing for industry-specific parameters in the production functions for output and knowledge, and in consumer preferences. We find that long run industry...

Do institutional firing costs slow the diffusion of information and communications technology (ICT)? The paper develops a model in which, as the technology at a given plant drops behind the best practice, it optimally reduces its workforce. As a result, firing costs are particularly detrimental...

This paper studies the role of entry and exit in the short run behavior of a general equilibrium model with industry dynamics. For tractability, and to preserve potential asymmetries in the impulse responses, I focus on the transition dynamics of the economy after shocks. Entry and exit are...
