摘要：We examine the effect of charge-price-transparency regulation (PTR)-a common policy solution intended to curb rising healthcare costs-on hospitals' prices. We find that, although PTR does not affect payments or consumer search, it does cause hospitals to reduce charges by approximately 5%. The reputational costs of perceived overcharging appear to be one impetus for the reduction in charges, suggesting that certain stakeholders who are able to impose costs on hospitals are unaware that hospita...

摘要：We study a fundamental model of resource allocation in which a finite number of resources must be assigned in an online manner to a heterogeneous stream of customers. The customers arrive randomly over time according to known stochastic processes. Each customer requires a specific amount of capacity and has a specific preference for each of the resources with some resources being feasible for the customer and some not. The system must find a feasible assignment of each customer to a resource o...

摘要：Rural consumers may face not only the challenge of affordability but also the problem of limited accessibility. Can a government's subsidy program effectively address these issues? This paper examines the impact of a large-scale subsidy program, Household electrical appliances going to the countryside, offered by the Chinese government. The government regulation imposes a price subsidy combined with a price ceiling on products in the program. We consider two effects of the subsidy: the retail ...

摘要：How do emerging market corporates fare during periods of currency depreciation? We find that nonfinancial firms that exploit favorable global financing conditions to issue U.S. dollar bonds and build cash balances are also those whose share price is most vulnerable to local currency depreciation. In particular, firms' vulnerability to currency depreciation derives less from the foreign currency debt as such, and more from the cash balances that are built up by using foreign currency debt. Over...

摘要：We examine the relationship between data analytics capabilities and innovation using detailed firm-level data. To measure innovation, we first utilize a survey to capture two types of firm practices, process improvement and new technology development for 331 firms. We then use patent data to further analyze new technology development for a broader sample of more than 2,000 publicly traded firms. We find that data analytics capabilities are more likely to be present and are more valuable in fir...

摘要：We combine ideas from machine learning (ML) and operations research and management science (OR/MS) in developing a framework, along with specific methods, for using data to prescribe optimal decisions in OR/MS problems. In a departure from other work on data-driven optimization, we consider data consisting, not only of observations of quantities with direct effect on costs/revenues, such as demand or returns, but also predominantly of observations of associated auxiliary quantities. The main p...

摘要：This paper examines how sentiment affects homebuyers' housing transaction decisions with a focus on auction sales. Utilizing housing transaction data in Sydney from 2000 to 2014, we find that transaction prices are significantly higher for auction sales compared with private sales, consistent with the notion of a winner's curse. Four sentiment proxies, including three weather-based sentiment proxies and a survey-based sentiment index, are used to derive novel measures of sentiment, revealing t...

摘要：We address the problem of designing appointment scheduling strategies in a stochastic environment accounting for patient no-shows, nonpunctuality, general stochastic service times, and unscheduled emergency walk-ins. A good appointment schedule seeks to help outpatient clinics to utilize their resources efficiently while containing patients' waiting times. The task of identifying an optimal schedule is modeled as a nonlinear integer program, where the objective function is the outcome of stoch...

摘要：This paper shows that liquidity conditions are important determinants of the predictability of earnings. Liquid stock prices are more informative about future firm earnings growth than illiquid stock prices. Because information-related illiquidity can arise when uncertainty is high, we focus our analysis on evidence that noninformational liquidity affects price informativeness. Endogeneity is further addressed using controls for market uncertainty and several exogenous shocks as natural experi...

摘要：Providing patients with timely care from the appropriate unit involves both correct clinical evaluation of patient needs and making admission decisions to effectively manage a unit with limited capacity in the face of stochastic patient arrivals and lengths of stay. We study human decision behavior in the latter operations management task. Using behavioral models and controlled experiments in which physicians and MTurk workers manage a simulated hospital unit, we identify cognitive and environ...
