摘要：Consumption decisions are partly influenced by values and ideologies. Consumers care about global warming, child labor, fair trade, etc. We develop an axiomatic model of intrinsic values-those that are carriers of meaning in and of themselves-and argue that they often introduce discontinuities near zero. For example, a vegetarian's preferences would be discontinuous near zero amount of animal meat. We distinguish intrinsic values from instrumental ones, which are means rather than ends and ser...

摘要：A principal often needs to match agents to perform coordinated tasks, but agents can quit or slack off if they dislike their match. We study two prevalent approaches for matching within organizations: centralized assignment by firm leaders and self -organization through market -like mechanisms. We provide a formal model of the strengths and weaknesses of both methods under different settings, incentives, and production technologies. The model highlights trade-offs between match -specific produ...

摘要：We study the market consequences of advances in consumption tracking technologies-such as mobile banking apps that help consumers monitor their spending and avoid overdrawn accounts-using a two -period consumption model. In the model, consumers pay a penalty fee if they consume in both periods. In the second period, consumers may be forgetful of their first -period consumption, although the use of consumption tracking can remind them. According to our analysis, the availability of consumption ...

摘要：Existing studies assume that all lenders have similar incentives to take on risks during different phases of the lending cycle. We show that foreign lenders and low market share lenders extend more credit in comparison with other lenders during lending booms leading to banking crises but not during other credit expansions. These less established lenders also shorten loan maturity and increase the amount of credit they extend to riskier borrowers without asking for collateral or imposing covena...

摘要：Determining emergency department (ED) nurse staffing decisions to balance quality of service and staffing costs can be extremely challenging, especially when there is a high level of uncertainty in patient demand. Increasing data availability and continuing advancements in predictive analytics provide an opportunity to mitigate demand uncertainty by using demand forecasts. In this work, we study a two-stage prediction-driven staffing framework where the prediction models are integrated with th...

摘要：In this paper, we pursue a correlation-robust study of the influence maximization problem. Departing from the classic independent cascade model, we study a diffusion process adversarially adapted to the choice of seed set. More precisely, rather than the independent coupling of known individual edge probabilities, we now evaluate a seed set's expected influence under all possible correlations, specifically, the one that presents the worst case. We find that the worst case expected influence ca...
