摘要：We investigate an editorial review program for which a review platform supplements user reviews with editorial ones written by professional writers. Specifically, we examine whether and how editorial reviews influence subsequent user reviews (reviews written by noneditor reviewers). A quasiexperiment conducted on a leading review platform in Asia, based on several econometric and natural language processing techniques, yields empirical evidence of an overall positive effect of editorial review...

摘要：Integrating inventory and assortment planning decisions is a challenging task that requires comparing the value of demand expansion through broader choice for consumers with the value of higher in-stock availability. We develop a stockout-based substitution model for trading off these values in a setting with inventory replenishment, a feature missing in the literature. Using the closed form solution for the single-product case, we develop an accurate approximation for the multiproduct case. T...

摘要：Using a panel of credit default swap (CDS) spreads and supply chain links, we observe that both favorable and unfavorable credit shocks propagate through supply chains in the CDS market. Particularly, the three-day cumulative abnormal CDS spread change (CASC) is 63 basis points for firms whose customers experienced a CDS up-jump event (an adverse credit shock). The value is 74 basis points if their suppliers experienced a CDS up-jump event. The corresponding three-day CASC values are -36 and -...

摘要：Blockholder monitoring is central to corporate governance, but blockholders large enough to exercise significant unilateral influence are rare. Mechanisms that enable moderately sized blockholders to exert collective influence are therefore important. Existing theory suggests that engagement by moderately sized blockholders is unlikely, especially when the blocks are held by delegated asset managers who have limited skin in the game. We present a model in whichmultiple delegated blockholders e...

摘要：We study an original equipment manufacturer (OEM) purchasing two inputs for assembly from two suppliers with private cost information. The OEM can contract with the two suppliers either simultaneously or sequentially. We consider both cases in which the OEM has relatively equal bargaining power (the dynamic bargaining institution) or substantial bargaining power (the mechanism design institution). For the dynamic bargaining institution, we show that in sequential bargaining, the supply chain p...
