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....

Most studies examining the impact of migrants on crime rates in hosting populations are in the context of economic migrants in developed countries. However, we know much less about the crime impact of refugees in low- and middle-income countries-whose numbers are increasing worldwide. This study...

We build an asset-pricing model with dynamic strategic competition to explain the strong joint fluctuations in aggregate discount rates, competition intensity, profitability, and asset prices. Product market competition endogenously intensifies as discount rates rise, because firms compete more...

We test the hypothesis that strategic interactions foster overconfidence. We experimentally compare an environment where players have an incentive to overstate their own ability to deter competitors, with one where this incentive is removed. We find that overconfidence persists in the former...

We develop models of markets with procrastinating consumers where competition operates - or is supposed to operate - both through the initial selection of providers and through the possibility of switching providers. As in other work, consumers fail to switch to better options after signing up...
