摘要：Price announcements-similar to the ones made by tech firms at media events-are effective in deterring innovation. By announcing (and setting) a high price, a firm increases its rivals' short-run profits, reducing the rival firms' incentives to innovate by magnifying their Arrow's replacement effect. We show that the equilibrium prices are greater and research and development (R&D) investments lower relative to when price announcements cannot be used strategically. We call this the R&D deterren...

摘要：Amid growing calls for transparency and social and environmental responsibility, companies are employing different strategies to improve consumer perceptions of their brands. Some pursue internal initiatives that reduce their negative social or environmental impacts through responsible operations practices (such as paying a living wage to workers or engaging in environmentally sustainable manufacturing). Others pursue external responsibility initiatives (such as philanthropy or cause-related m...

摘要：We study a multilocation newsvendor model with a retailer owning multiple retail stores, each of which is operated by a manager who decides the order quantity for filling random customer demand of a product. Store managers and the retailer are all risk averse, but managers are more risk averse than the retailer. We adopt conditional value-at-risk (CVaR) as the performance measure and consider two alternative strategies to improve the system's performance. First, the retailer centralizes the or...

摘要：Large institutional investors own an increasing share of the equity markets in the United States. The implications of this development for financial markets are still unclear. The paper presents novel empirical evidence that ownership by large institutions predicts higher volatility and greater noise in stock prices as well as greater fragility in times of crisis. When studying the channel, we find that large institutional investors exhibit traits of granularity (i.e., subunits within a firm d...

摘要：We study a novel, low-cost approach to aggregating judgment from a large number of industry experts on ideas that they encounter in their normal course of business. Our context is the movie industry, in which customer appeal is difficult to predict and investment costs are high. The Black List, an annual publication, ranks unproduced scripts based on anonymous nominations from film executives. This approach entails an inherent trade-off: Low participation costs enable high response rates, but ...

摘要：In this paper, I provide some observations on how the academic field of operations management has changed over the past 40 years. For this purpose, I have identified and classified the operations management (OM) papers published in Management Science in 1976 and in 2016. From this review, I comment on what's changed, what's new, and what we might see in the future. In reflecting on these changes, I also document and discuss how the OM editorial structure and mission have evolved at Management ...

摘要：When a supplier fails to comply with social and environmental standards, the buyer's reputation suffers. Reputation costs can typically be very high for the buyer, whereas the supplier's liability is often limited. Conventional procurement strategies such as dual sourcing mitigate the buyer's operational risk, but they often do so at the expense of increasing its reputation risk and sourcing costs. In this paper, we propose a risk-sharing contract for managing the buyer's reputation concerns. ...

摘要：We study the power of selling opaque products, that is, products where a feature (such as color) is hidden from the customer until after purchase. Opaque products, which are sold with a price discount, have emerged as a powerful vehicle to increase revenue for many online retailers and service providers that offer horizontally differentiated items. In the opaque selling models we consider, all of the items are sold at a single common price alongside opaque products that may correspond to vario...

摘要：Intertemporal discount rates vary widely across contexts and individuals. We propose that a sizable fraction of this variation results from differences in how visual attention is allocated to different features of the decision, such as earlier versus future rewards, and that fluctuations in attentional patterns alter choices. We first tested this hypothesis in an experiment in which participants chose between receiving smaller-sooner versus larger-later monetary rewards while their attention w...

摘要：Digital platforms provide a variety of technology-enabled tools that enhance market transparency, such as real-time monitoring, ratings of buyers and sellers, and low-cost complaint channels. How do these innovations affect moral hazard and service quality? We investigate this problem by comparing driver routing choices and efficiency on a large digital platform, Uber, with traditional taxis. The identification is enabled by matching taxi and Uber trips at the origin-destination-time level so ...
