摘要：Using thousands of brokerage accounts of U.S. individual investors, we analyze the motivations and consequences of foreign equity investment. We find that diversification is not the only reason that investors trade foreign securities. While wealthier, more experienced investors enjoy an informational advantage and, thus, are more likely to invest overseas and experience good portfolio performance, other investors appear to venture. abroad for the wrong reasons. In particular, behaviorally bias...

摘要：In this paper, we develop a simultaneous model of consumer brand choice and negotiated price in the highly relevant marketing context of automobile transactions. Consumer brand choice is modeled as a multinomial probabilistic outcome, and the individual consumer-level transaction price is modeled to be consistent with the Nash bargaining solution. Our simultaneous model introduces a natural way to account for price endogeneity in a microlevel choice setting when the price paid is individual sp...

摘要：This paper transfers the concept of Gollier and Pratt's (Gollier, C., J. W. Pratt. 1996. Risk vulnerability and the tempering effect of background risk. Econometrica 64 1109-1123). risk vulnerability into mean variance preferences. Risk vulnerability is shown to be equivalent to the slope of the mean variance indifference curve being decreasing in mean and increasing in variance. Next, we introduce the notion of mean variance vulnerability to link the concepts of decreasing absolute disk avers...

摘要：We consider the problem of minimizing staffing costs in an inbound call center, while maintaining an acceptable level of service in multiple time periods. The problem is complicated by the fact that staffing level in one time period can affect the service levels in. subsequent periods. Moreover, staff schedules typically take the form of shifts covering several periods. Interactions between staffing levels in different time periods, as well as the impact of shift requirements on the staffing l...

摘要：The people living and working around the roads used for hazardous material (hazmat) shipments face the risk of suffering undesirable consequences of an accident. The main responsibility to mitigate the hazmat transport risk at a population zone belongs to the government agency with jurisdiction over that region. One of the common policy tools is to close certain road links to vehicles carrying hazmats. In effect, the road network available to dangerous goods carriers can be determined by the r...
