Static competitive equilibria in economies with incomplete markets are generically constrained suboptimal. Allocations induced by strategic equilibria of imperfectly competitive markets are also generically inefficient. In both cases, there is scope for Pareto-improving amendments. In an...

In past years, imperfect competition has been introduced in several dynamic models to show how mark-up variability, increasing returns (decreasing marginal cost) and monopoly profits affect the occurence of endogenous fluctuations. In this paper, we focus on another possible feature of...
