We show that in multi-sector optimal growth models, where the technology satisfies a simple reachability condition, infinite horizon programs which satisfy the competitive conditions are optimal. We provide examples of a variety of production models where the reachability condition is satisfied....

This paper shows how heterogeneity in wage setting and a link between nominal wage flexibility and goods-market competition arise in a multisector economy that is affected by aggregate and sector-specific shocks. Aggregate volatility increases the variance of real contract wages, whereas...

It is commonly argued that labor market institutions such as employment protection worsen an economy's performance and particularly so, if product markets become more competitive. Empirical evidence, however, has difficulties to detect a robust negative correlation between employment protection...

This article proposes a dynamic efficiency wages model with imperfect competition on labor and product markets. In this framework, job insecurity generates a perverse effect on workers incentives, which shifts up the real wages schedule and may yield employment losses. Product market regulation...
