Urgent care centers (UCCs) are a cost-efficient substitute to the emergency department (ED) for non-emergent conditions, but no study has identified their impact on ED demand. We address this gap using a novel strategy that exploits daily UCC operating times in a differencing framework. After...

We have assessed the determinants of the choice of integration, relational contracting (keiretsu sourcing) and market sourcing by seven Japanese automobile manufacturers (OEMs) with respect to 54 components in light of contract economics. Our major findings are the following. First, the...

A large and growing share of international trade is carried on airplanes. Air cargo is many times more expensive than maritime transport but arrives in destination markets much faster. We model firms' choice between exporting goods using fast but expensive air cargo and slow but cheap ocean...
