摘要：Rapid technological developments in online markets fundamentally change relationship between consumers and sellers. Online platforms can easily gather data consumers' search behavior, allowing for price discrimination. Therefore, product becomes a strategic choice. Consumers face a tradeoff: Search intensely and receive fit at a potentially higher price or restrict search behavior, be strategically inattentive, receive a worse fit but maybe a better deal. We study the resulting strategic buyer...

摘要：Healthcare organizations have been adopting video visits as an alternative care channel that offers greater convenience and holds promise for improving patients' access to care. Despite the growing use, the impact of a new digital channel on care demand within existing physical channels has not been investigated in detail, especially in the primary care context of a traditional healthcare organization. We study a large healthcare system that made video visits available to a subset of its patie...

摘要：Suppliers operating in developing economies may resort to compelling their workforce to engage in excessive overtime, resulting in severe physical and mental health issues for workers and the potential for significant damage to the brand image of multinational enterprises (MNEs) if these practices are exposed to the public. In this paper, we develop a game-theoretic model of a dyadic supply chain to analyze a manufacturer's operational strategies to combat the use of excessive overtime by a su...

摘要：Motivated by our collaboration with a major refugee resettlement agency in the United States, we study a dynamic matching problem where each new arrival (a refugee case) must be matched immediately and irrevocably to one of the static resources (a location with a fixed annual quota). In addition to consuming the static resource, each case requires postallocation service from a server, such as a translator. Given the time-consuming nature of service, a server may not be available at a given tim...

摘要：We examine how privacy restrictions affect online content creation and consumption by evaluating the impact of YouTube's settlement with the Federal Trade Commission over violating the Children's Online Privacy Protection Act. Under the settlement, YouTube limited personalization for made-for-kids (MFK) content starting in January 2020, and this included personalized ads and content engagement features such as subscriber notifications and playlists. We study the resulting impact on 5,066 top A...

摘要：This paper examines how infrastructure development affects stock market participation in India using trading data from more than 13 million individuals. Using the phased rollout of a national road construction program as a natural experiment, we find that new road connections lead to significant increases in both trading activity and the number of investors. These effects are driven primarily by new market entrants and are most pronounced in rural and intermediately developed regions as well a...

摘要：We study serial supply chain problems where a product is transported from a supplier to a warehouse (inbound transportation), and then from the warehouse (outbound transportation) to a retailer such that demand for a given planning horizon is satisfied. We consider heterogeneous vehicles of varying capacities for transportation in each time period, and the objective is to plan inbound and outbound transportation along with inventory in each time period so that overall inventory and transportat...

摘要：Studying a large set of macroeconomic announcements (MAs) and disentangling their news content, we show that a portfolio of stocks that pays off around MAs that negatively impact the aggregate stock market commands a positive risk premium. Adding this portfolio to a position in the aggregate market substantially increases Sharpe ratio while reducing MA risk exposure, which implies a rejection of the CAPM. Using state-ofthe-art measures of cash flow and discount rate news and consistent with pr...

摘要：This paper proposes and implements a novel nonparametric method for estimating the state price density (SPD) over the entire state space, including the tails. This SPD estimator achieves shape consistency properties in theory, particularly at the tails. Monte Carlo simulations demonstrate the accuracy and robustness of our method. In particular, our estimator accurately captures the risk-neutral tail distribution, which is often underestimated by existing alternative methods. In an empirical a...

摘要：Risk pooling has become an increasingly critical tool for managing risks among corporations, institutions, states, and nations, with examples including multinational pooling, decentralized insurance schemes, catastrophe risk pooling, and burden sharing for nuclear accidents. Although there has been a rich literature on such practices, little is known from a theoretical viewpoint regarding the operational strategies of risk pools and, in particular, on issues about the effect of a pool's expans...
