摘要:The relationship between pharmaceutical detailing and prescriptions for non-FDA-approved (off-label) use has been the subject of regulatory scrutiny, with more than $12 billion in regulatory settlements for off-label promotion since 2004. Using the case of AstraZeneca's antipsychotic drug, Seroquel, I study the extent to which off-label prescriptions are caused by detailing. Using a physician panel that connects detailing exposure to medical charts, I exploit within-physician variation to iden...

摘要:Small suppliers often face challenges to obtain financing for their operations. Especially in developing economies, traditional financing methods can be very costly or unavailable to such suppliers. To reduce channel costs, large buyers have recently begun implementing their own financing methods that intermediate between suppliers and financing institutions. In this paper, we analyze the role and efficiency of buyer intermediation in supplier financing. Building a game-theoretical model, we s...

摘要:We study the selection and dynamics of two popular pricing policies-fixed price and flexible price-in competitive markets. Our paper extends previous work in marketing, for example, Desai and Purohit (2004) by focusing on decentralized markets with a dynamic and fully competitive framework while also considering possible noneconomic aspects of bargaining. We construct and analyze a competitive search model, which allows us to endogenize the expected demand depending on pricing rules and posted...

摘要:We use a field experiment in Sierra Leone to examine how the identity of the manager influences rent seeking and performance in participatory development projects. Specifically, we vary the composition of a committee responsible for implementing a development project-local elites or randomly selected villagers. The design is unique in that it permits us to explore the effectiveness of two alternative local governance modalities and the extent of elite capture in community projects. We find lit...

摘要:We partner with a major multinational telecommunications provider to analyze the effect of subscription video-on-demand (SVoD) services on digital piracy. For a period of 45 consecutive days, a group of randomly selected households who used BitTorrent in the past were gifted with a bundle of TV channels with movies and TV shows that could be streamed as in SVoD. We find that, on average, households that received the gift increased overall TV consumption by 4.6% and reduced Internet downloads a...

摘要:We investigate whether managerial traits influence corporate decisions to provide mandatory financial disclosures. The results indicate that firms with confident chief executive officers (CEOs) are 24% more likely to report their research and development (R&D) expenditures relative to firms with cautious CEOs. Exploiting staggered, state-level regulatory shocks and changes in CEO type, we find substantial evidence that cautious CEO firms fail to report R&D expenditures. After a plausibly exoge...

摘要:To refine the understanding of the social network characteristics of entrepreneurial teams, we present a new construct: structural role complementarity. In particular, we examine the variation between team members' respective abilities to act as network brokers. Based on the cofounding networks of 9,461 entrepreneurs and 2,446 large-scale industrial enterprises over 45 years in Russia's emerging economy (1869-1913), our findings show that variation among team members' brokering ability signifi...

摘要:We examine how the entry of gig-economy platforms influences local entrepreneurial activity. On the one hand, such platforms may reduce entrepreneurial activity by offering stable employment for the unemployed and underemployed. On the other hand, such platforms may enable entrepreneurial activity by offering work flexibility that allows the entrepreneur to redeploy resources strategically in order to pursue the nascent venture. To resolve this tension, we examine the entry of the ridesharing ...

摘要:This paper presents a theory of disclosure in a market where investors have heterogeneous beliefs and face short-sale constraints. Assets trade above fundamentals reflecting the value of the option to sell to more optimistic investors in the future. The initial seller has an incentive to commit to an imprecise disclosure policy, despite the negative effect this has on the fundamental value of the asset, in order to increase the potential for disagreement and hence the magnitude of the speculat...

摘要:This study examines whether revolving rating analysts who transition from major rating agencies to issuers are associated with any rating inflation in the issuers' mortgage-backed securities (MBS) or asset-backed securities (ABS). Using professional profiles posted on LinkedIn to identify revolving rating analysts with structured finance rating experience, we find that the more the issuers employ such analysts, the more likely that ratings of issuers' MBS and ABS new issuances are inflated com...
