摘要:Mandatory filings for UK hedge funds suggest that managers having worked at the same prior employer invest more similarly in terms of distances of returns. If they overlapped in employment, increasing the chance of social ties, investments become even more similar. The joint effect accounts for up to two thirds of the difference in investing behavior. Results are robust to fund-and manager-level controls as well as to identification concerns. With controls, the same-employer effect is concentr...

摘要:Educational inequality undermines the pivotal role of education in increasing the ability of the poor to move up the income ladder. This paper investigates educational inequality that arises from low-income students' lack of monetary resources that higherincome students invest in education. We show low-income students' inability to make monetary investments in education reduces their incentive to study and contributes to educational inequality. In the context of developing markets, we study im...

摘要:We examine the impact of government interventions on the spread of COVID19 and consumer spending. We do this by first estimating models of COVID-19 spread, consumer spending, and social distancing in the United States during the early stages of the COVID-19 pandemic. Social distancing has a large effect on reducing COVID-19 spread and is responsive to national and local case numbers. Nonmask government interventions reduce COVID-19 spread, whereas the effectiveness of mask mandates is much sma...

摘要:A significant proportion of the world's population has no access to grid-based electricity and so relies on off-grid lighting solutions. Rechargeable lamp technology is gaining popularity as an alternative off-grid lighting model in developing countries. In this paper, we explore consumer behavior and the operational inefficiencies that result under this model. Specifically, we are interested in (i) measuring the impact of inconvenience (of traveling to recharge the lamp) along with the impact...

摘要:Retailers managing both online and offline channels have to decide whether to adopt the uniform (i.e., charging the same price online and offline) or dual (i.e., charging different prices online and offline) pricing strategy. This decision is made even more challenging as consumers are increasingly multirooming as they may search offline and then purchase online (showrooming) or the other way around (webrooming). In this paper, we develop an analytical model to examine such a decision. The mod...

摘要:We conducted a large-scale personalized field experiment to examine how match quality, recognition, and social impact influence domain experts' contributions to Wikipedia. Forty-five percent of the experts expressed willingness to contribute in the baseline condition, whereas 51% (a 13% increase over the baseline) expressed interest when they received a signal that an article matched their expertise. However, none of the treatments had a significant effect on actual contributions. Instead expe...

摘要:Little is known about how people-centric factors affect the shape of service time distributions despite distributional statistics (variance or quantiles) being key drivers of system performance in many service industries. We investigate the impact of one people-centric factor-worker fatigue-on the average, variance, and quantiles of service times in paramedic operations. Our analysis uses data on the performance of 368,634 paramedic teams in the London Ambulance Service over 10 years. We measu...

摘要:This paper challenges two common views of brand dilution: first, that it is exclusively the unintended consequence of a poorly executed strategy of brand extension and, second, that its likelihood is heightened by brand licensing. Using a new theoretical model, we show that brand dilution can be seen not just as an unfortunate development to be avoided, but as an opportunity to monetize the brand. We further show that, at the relevant margin, switching from in-house development to licensing re...

摘要:Investment mandates of fixed income funds constrain managers' portfolio decisions, often employing credit ratings to classify asset risk. We categorize U.S. and European fixed income funds' mandates using textual analysis and measure the use of ratings. Over the past two decades, despite the weaknesses of ratings revealed in the global financial crisis, ratings use has increased significantly. Since 2010, the fraction of funds not using ratings in any way has fallen by almost half in both the ...
