摘要:A country's human capital and economic productivity increasingly depend on the Internet as a result of its expanding role in providing information and communications. This has prompted a search for ways to increase Internet adoption and narrow its disparity across countries-the global digital divide. Previous work has focused on demographic, economic, and infrastructure determinants of Internet access that are difficult to change in the short run. Internet content increases adoption and can be...

摘要:This paper demonstrates that speculative activities can be contagious and spill over across markets. Specifically, we test the hypothesis that during China's warrants bubble period, speculative activities in the warrants market grabbed investors' attention and caused them to trade more speculatively in the underlying stocks. Consistent with this hypothesis, we find that turnover and return volatility of the underlying stocks are positively associated with the warrants' unexpected turnover and ...

摘要:Databases play a central role in evidence-based innovations in business, economics, social, and health sciences. In modern business and society, there are rapidly growing demands for constructing analytically valid databases that also are secure and protect sensitive information to meet customer and public expectations, to minimize financial losses, and to comply with privacy regulations and laws. We propose new data perturbation and shuffling (DPS) procedures, named MORE, for this purpose. As...

摘要:The centralization versus decentralization choice is perhaps the quintessential organizational structure decision. In the operations realm, this choice is particularly critical when it comes to the procurement function. Why firms may opt to decentralize procurement has been often studied and confirmed to be a multifaceted choice. This paper complements existing studies by detailing the trade-offs in the centralization versus decentralization decision in light of firms' strategic use of invento...

摘要:A retailer's assortment decision results from a process of give-and-take, during which the retailer may bid manufacturers against one another, and the terms of trade offer plenty of flexibility for allocating the profit among the retailer and manufacturers. We adopt a bargaining framework to capture such an assortment selection process. We investigate the properties of the profit allocations that could emerge in a decentralized supply chain. In our model, the retailer engages in simultaneous b...

摘要:We consider a seller who can sell her product over two periods, advance and spot. The seller has private information about the product quality, which is unknown to customers in advance and publicly revealed in spot. The question we consider is whether the seller has an incentive to signal quality in advance and, if so, how she can convey a credible signal of product quality. We characterize the seller's signaling strategy and find that rationing of capacity in the advance period is an effectiv...

摘要:We report on a within-subject experiment, with substantial monetary incentives, designed to test whether or not people are risk vulnerable. In the experiment, subjects face the standard portfolio choice problem in which the investor has to allocate part of his wealth between one safe asset and one risky asset. We elicit risk vulnerability by observing each subject's portfolio choice in two different contexts that differ only by the presence or absence of an actuarially neutral background risk....

摘要:We take a novel approach to decision problems involving binary activity-selection decisions competing for scarce resources. The literature approaches such problems by forming an optimal portfolio of activities. However, often practitioners instead form a rank-ordered list of activities and select those with the highest priority. We account for both viewpoints. We rank activities considering both the uncertainty in the problem parameters and the optimal portfolio that will be obtained once the ...

摘要:In using the generalized second-price (GSP) auction to sell advertising slots, a search engine faces several challenges. Advertisers do not truthfully bid their valuations, and the valuations are uncertain. Furthermore, advertisers are budget constrained. In this paper we analyze a stylized model of the first-page bid estimate (FPBE) mechanism first developed by Google and demonstrate its advantages in dealing with these challenges. We show why and when the FPBE mechanism yields higher profits...

摘要:Data on inventors and assignees of patents are used to analyze the mobility of semiconductor inventors. Exploiting data on the origins of semiconductor producers with larger sales, we argue that the higher mobility of semiconductor inventors in Silicon Valley is in great part due to the entry of spinoffs there. Our empirical evidence suggests that spinoff entry promoted mobility in Silicon Valley even before the industry was clustered there. Agglomeration economies and the ban on noncompete co...
