摘要：Using a network approach that circumvents well-known challenges in estimating peer effects, we show that interactions with a firm's geographic neighbors play a significant causal role in corporate investment behavior and a modest role in financial policies and firm performance. Moreover, these geography network effects are almost entirely driven by propagation effects through product market and supply chain networks. We corroborate our findings in a quasi-experimental framework that allows for...

摘要：We consider a sales effort management problem under an all-or-nothing constraint. The seller will receive no bonus/revenue if the sales volume fails to reach a predetermined target at the end of the sales horizon. Throughout the sales horizon, the sales process can be moderated by the seller through costly effort. We show that the optimal sales rate is nonmonotonic with respect to the remaining time or the outstanding sales volume required to reach the target. Generally, it has a watershed str...

摘要：This paper proposes a novel supervised learning technique for forecasting: scaled principal component analysis (sPCA). The sPCA improves the traditional principal component analysis (PCA) by scaling each predictor with its predictive slope on the target to be forecasted. Unlike the PCA that maximizes the common variation of the predictors, the sPCA assigns more weight to those predictors with stronger forecasting power. In a general factor framework, we show that, under some appropriate condit...

摘要：Managing large-scale systems often involves simultaneously solving thousands of unrelated stochastic optimization problems, each with limited data. Intuition suggests that one can decouple these unrelated problems and solve them separately without loss of generality. We propose a novel data-pooling algorithm called Shrunken-SAA that disproves this intuition. In particular, we prove that combining data across problems can outperform decoupling, even when there is no a priori structure linking t...

摘要：Florida, an important state in presidential elections in the United States, has received considerable media coverage in recent years for long lines to vote. Do some segments of the population receive a disproportionate share of the resources to serve the voting process, which could encourage some or dissuade others from voting? We conduct the first empirical panel data study to examine whether minority and Democrat voters in Florida experience lower poll worker staffing, which could lengthen t...

摘要：We examine the teams that emerge when a primary care physician (PCP) refers patients to specialists. When PCPs concentrate their specialist referrals???for instance, by sending their cardiology patients to fewer distinct cardiologists???repeat interactions between PCPs and specialists are encouraged. Repeated interactions provide more opportunities and incentives to develop productive team relationships. Using data from the Massachusetts All Payer Claims Database, we construct a new measure of...

摘要：We develop a model of competition between banks and a marketplace lender to motivate empirical tests using local market data on U.S. banks and the largest marketplace lending platform. Employing mergers of large, multimarket banks as an exogenous credit supply shock, we find that marketplace lending absorbs unmet demand for consumer credit following a decline in the availability of bank credit. Merger-induced bank branch closings lead to an increase in marketplace loan requests and loan accept...

摘要：During a heat wave on a summer afternoon, a utility firm may face unusually high demand and procurement cost for electricity. Under such conditions, a demandresponse event occurs, and the firm asks residential customers to reduce their demand. Such a demand-response program not only reduces the firm's procurement cost, but it can also be environmentally beneficial by reducing generation from emissions-intensive power plants. In a demand-response program, a utility firm pays a rebate to custome...

摘要：We study a general problem of allocating limited resources to heterogeneous customers over time under model uncertainty. Each type of customer can be serviced using different actions, each of which stochastically consumes some combination of resources and returns different rewards for the resources consumed. We consider a general model in which the resource consumption distribution associated with each customer type-action combination is not known but is consistent and can be learned over time...

摘要：We consider joint learning and optimization problems under a general Cascade Click model. Under this model, customers examine the products in a decreasing order of display, from the top to (potentially) the bottom of the list. At each step, customers can decide to either purchase the current product, forego the current product and continue examining the next product, or simply terminate the search without purchasing any product. We first consider the core pricing problem, where the display pos...
