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...

This chapter examines the relationship between agent-based modeling and economic decision-making experiments with human subjects. Both approaches exploit controlled “laboratory” conditions as a means of isolating the sources of aggregate phenomena. Research findings from laboratory studies...
