摘要：The transportation sector's carbon footprint and dependence on oil are of deep concern to policy makers in many countries. Use of all-electric drive trains is arguably the most realistic medium-term solution to address these concerns. However, motorist anxiety induced by an electric vehicle's limited range and high battery cost have constrained consumer adoption. A novel switching-station-based solution is touted as a promising remedy. Vehicles use standardized batteries that, when depleted, c...

摘要：We address the contested state of theory and the mixed empirical evidence on the relationship between turbulence and vertical scope by studying how turbulence affects the benefits of commitment from integrated development of components and the benefits of flexibility from sourcing components externally. We show that increasing turbulence first increases but then decreases the relative value of vertical integration. Moderate turbulence reduces the value of flexibility by making supplier selecti...

摘要：Data on inventors and assignees of patents are used to analyze the mobility of semiconductor inventors. Exploiting data on the origins of semiconductor producers with larger sales, we argue that the higher mobility of semiconductor inventors in Silicon Valley is in great part due to the entry of spinoffs there. Our empirical evidence suggests that spinoff entry promoted mobility in Silicon Valley even before the industry was clustered there. Agglomeration economies and the ban on noncompete co...

摘要：We study queue abandonment from a hospital emergency department. We show that abandonment is influenced by the queue length and the observable queue flows during the waiting exposure, even after controlling for wait time. For example, observing an additional person in the queue or an additional arrival to the queue leads to an increase in abandonment probability equivalent to a 25-minute or 5-minute increase in wait time, respectively. We also show that patients are sensitive to being jumped i...

摘要：The real option management of commodity conversion assets gives rise to intractable Markov decision processes (MDPs), in part because of the use of high-dimensional models of commodity forward curve evolution, as commonly done in practice. Focusing on commodity storage, we identify a deficiency of approximate linear programming (ALP), which we address by developing a novel approach to derive relaxations of approximate linear programs. We apply our approach to obtain a class of tractable ALP re...

摘要：This paper investigates how venture-backed companies are affected when others sharing the same investor suffer a negative shock. In theory, companies may be helped or hurt in this scenario. To examine the topic empirically, I estimate the impact of the collapse of the technology bubble on non-information-technology (non-IT) companies that were held alongside IInternet companies in venture portfolios. Using a difference-indifferences framework, I find that the end of the bubble was associated w...

摘要：The presence of workers who reciprocate higher wages with greater effort can have important consequences for firms and labor markets. Knowledge about the extent and determinants of reciprocal effort choices is, however, incomplete. We investigate the role of fairness perceptions and social preferences in a field experiment in which workers were hired for a one-time job. We show that workers who perceive being underpaid at the base wage increase their performance if the hourly wage increases, w...

摘要：B Companies are increasingly drawing on their user communities to generate promising ideas for new products, which are then marketed as user-designed products to the broader consumer market. We demonstrate that nonparticipating, observing consumers prefer to buy from user-rather than designer-driven firms because of an enhanced identification with the firm that has adopted this user-driven philosophy. Three experimental studies validate a newly proposed social identification account underlying...

摘要：We investigate the role of physical attractiveness in the hiring process. We sent 5,312 curricula vitae (CVs) in pairs to 2,656 advertised job openings. In each pair, one CV was without a picture, whereas the second, otherwise almost identical CV contained a picture of either an attractive male or female or a plain-looking male or female. Employer callbacks to attractive men are significantly higher than to men with no picture and to plain-looking men, nearly doubling the latter group. Strikin...

摘要：In this paper, I elicit risk attitudes of U.S. executives by calibrating a subjective option valuation model for option exercising data (1996 to 2008), yielding approximately 65,000 values of relative risk aversion (RRA) for almost 7,000 executives. The observed behavior is generally consistent with moderate risk aversion and a median (mean) RRA close to one (three). Values are validated for chief executive officers (CEOs) by testing theory-based predictions on the influence of individual char...
