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：We build a risk management model that incorporates variable capital utilization and time -varying collateral capacity. The former lets firms optimally choose capital utilization, and hence production, which affects capital depreciation and risk exposure. The latter means firms' ability to borrow and hedge increases with expected earnings and thus utilization. Calibrated solutions show both ingredients matter for firm value. We test the novel model predictions using a new data set of oil and ga...

摘要：Largely constant average acquirer returns over the past four decades mask fundamental changes in the takeover market. Controlling for bidder composition, the common component of acquirer returns has increased by five percentage points relative to the 1980s. Offsetting this increase, the average bidder-specific component has declined. We propose a theory of bidder-specific synergies to help interpret these opposing trends. In our theory and in the data, acquirer returns increase with the extent...

摘要：The currency market is the world's largest financial market by trading volume. We show that even in this highly liquid market, exposure to liquidity risk commands an economically significant risk premium of up to 3.6% per year. Liquidity risk is not subsumed by existing currency risk factors and successfully prices the cross section of currency excess returns. Moreover, we find that liquidity risk and carry trade premia are correlated, although this correlation is limited to static rather than...

摘要：Standard models of decision making under risk and uncertainty are deterministic. Inconsistencies in choices are accommodated by separate error models. The combination of decision model and error model, however, is arbitrary. Here, I derive a model of decision making under uncertainty in which choice options are mentally encoded by noisy signals, which are optimally decoded by Bayesian combination with preexisting information. The model predicts diminishing sensitivity toward both likelihoods a...

摘要：Do consumers search the brands they know more or less frequently than the brands with which they are unfamiliar? In this paper, we attempt to answer this question using data from an experiment with two novel features: (i) survey information on consumers' prior brand ownership, familiarity with each brand, and prior experience using different product features and (ii) eye -tracking data capturing search behavior at a very granular level. We find that consumers are generally more likely to searc...

摘要：The optimal number of products to offer consumers is one of the core strategic problems that firms face. This is increasingly so in digital markets where many firms offer a large product variety. In these markets, consumers purchase products repeatedly, making customer retention an important aspect for firm performance. In this paper, we study the interplay between these two variables, product variety and customer retention. First, we provide a novel game-theoretic model to analyze this interp...

摘要：We study competition between two firms that personalize product offerings to consumers. Firms have private, imperfect signals of each consumer's ideal location and offer each consumer a different product without observing the competitor's product offering. We characterize the equilibrium personalization strategy and examine how the accuracies of firms' signals affect equilibrium strategy, profits, and consumer welfare. A firm generally charges a higher price for a more niche product and profit...

摘要：This paper examines the preferences of 10,000 capital owners worldwide, including nearly 3,000 from the world's largest sovereign wealth fund, regarding green shareholder voting and divestment. Findings indicate substantial support (53%-72%) for shareholder engagement and green voting, which is more popular and less politically divisive than divestment. Preferences for green voting increase with the likelihood of green outcomes being implemented though 63% of the payoff is attributed to expres...

摘要：The Locker Alliance Network (LAN), a cutting-edge initiative under Singapore's Smart Nation vision, aims to revolutionize parcel pickup processes. This government-led project seeks to implement two major changes in Singapore's urban logistics: (i) establishing an open-access facility for all logistic service providers (LSPs) and (ii) enhancing the last mile delivery efficiency of each LSP, thereby reducing its operational footprint. This research investigates the impact of locker network desig...
