摘要：What are the determinants of in-house employment versus outsourcing in the service sector? I use detailed data on U.S. lobbying services to answer this question. I argue with a series of correlational exercises that firms tend to outsource lobbying tasks that demand a large amount of general skills, whereas they are more likely to assign firm specific tasks to in-house lobbyists. I provide causal evidence that the need to do tasks that vary in their general skill component leads to a change in...

摘要：Assortment rotation-the retailing practice of changing the assortment of products offered to customers-has recently been used as a competitive advantage for both brick-and-mortar and online retailers. We focus on product categories where consumers may purchase multiple products during a season and investigate a new reason why frequent assortment rotations can be valuable to a retailer. Namely, by distributing its seasonal catalog of products over multiple assortments rotated throughout the sea...

摘要：Credible causal inference in accounting and finance research often comes from natural experiments. These experiments can be exploited using several shock-based research designs, including difference in differences (DID), shock-based instrumental variable (shock-IV), and regression discontinuity. We study here shock-IV designs using panel data. We identify all shock-IV papers in two broad data sets and reexamine three of the apparently strongest papers-Desai and Dharmapala [Desai M, Dharmapala ...

摘要：Do mass media bias content in favor of advertisers? If so, what market conditions limit or exacerbate this bias? We examine the relationship between advertising by auto manufacturers in U.S. newspapers and news coverage of car safety recalls between 2000 and 2014. This context allows us to separate the influence of advertisers, who prefer less coverage, from that of readers, who prefer more information about the safety risks associated with the recalls. Consistent with theoretical predictions,...

摘要：Dockless bike sharing provides a convenient and affordable means of transport for urban residents. It solves the last-mile problem in public transport by reducing the travel cost between home and subway stations and thus increasing the attractiveness of distant apartments. This may affect the relationship between housing price and distance to subway and reduce the price premium enjoyed by proximate apartments. Using resale apartment data in 10 major cities in China, a difference-in-differences...

摘要：We report the results of two field experiments in a retail chain and show that the effectiveness of performance pay crucially hinges on prior job experience. Introducing sales-based performance pay first for district managers and later for store managers, we find negligible average treatment effects. From surveys and interviews, we develop a formal model demonstrating that the effect of performance pay decreases with experience and may even vanish in the limit. We provide empirical evidence in...

摘要：We consider a single product dynamic pricing with demand learning. The candidate prices belong to a wide range of a price interval; the modeling of the demand functions is nonparametric in nature, imposing only smoothness regularity conditions. One important aspect of our model is the possibility of the expected reward function to be nonconcave and indeed multimodal, which leads to many conceptual and technical challenges. Our proposed algorithm is inspired by both the Upper-Confidence-Bound a...

摘要：We review past research and discuss future directions on how the vibrant re-search areas of market design and behavioral economics have influenced and will continue to impact the science and practice of management in both the private and public sectors. Using examples from various auction markets, reputation and feedback systems in online markets, matching markets in education, and labor markets, we demonstrate that com-bining market design theory, behavioral insights, and experimental methods...

摘要：Optimization has been one of the most fundamental and extensive contributions of management science/operations research, with an enormous number of contributions and subfields developed by many researchers and practitioners. When the journal Management Science launched in 1954, little was known about optimization, including some results in nonlinear optimization and the simplex method and duality developed for linear programming. However, linear programming computations were limited to problem...
