摘要：This paper studies the effects of bank credit availability, trade credit and the capital cost on inventory decisions. There are two competing theories on the effect of bank credit lines on investments. While one (Lins et al. 2010) suggests that the primary role played by undrawn credit is to finance new opportunities, the other (Acharya et al. 2014) suggests that undrawn credit serves primarily as a bank monitored liquidity insurance. We attempt to resolve these two conflict views in the conte...

摘要：We study the widespread practice of assigning a single surgeon to two operating rooms (ORs), which is known as overlapping surgery. We first describe the fundamental trade-offs that motivate hospitals to employ the practice. Then, we conduct a mathematical analysis for the completion of a set of elective operations under an overlapping surgery policy and a more traditional, serial scheduling policy. We use this analysis, along with a cost function that considers surgeon idle time and total OR ...

摘要：Even with the rapid proliferation of applications (apps) running on smart handheld devices, achieving success in mobile platform ecosystems is challenging for developers because of the heavily crowded marketplaces and easy substitutability of apps. In this study, we draw inspiration from biological ecosystems research and from the operations management literatures on software production, product management, and digital platforms to empirically examine the sustainability of newly launched apps ...

摘要：This study investigates a novel mechanism-multiple-winner award rules-that are widely used in e-procurement auctions and crowdsourcing sites. In many e-procurement auctions, the auctioneer (i.e., the buyer) specifies three rules before the auction starts: (i) the size of the finalist set (from which the winner[s] will be chosen); (ii) the number of winners; and (iii) the allocation of the contract among the winners. We examine how these three rules affect auction performance using a dataset of...
