摘要：In a field experiment, we find that a mandatory mentorship program raises worker productivity, whereas a voluntary version of the program does not. A significant reason why the mandatory program results in larger gains is that the lowest-productivity employees do not participate when the program is voluntary despite their having the greatest treatment benefits. A nationally representative survey of U.S. workers shows wide variation in human capital development program participation, suggesting...

摘要：Firms are increasingly moving away from proprietary technology to building commercial products on top of open source software. However, it is unclear how such commercialization of open source affects contributions from the community, as well as product quality and firm performance. Web browser technology provides a unique setting to study such questions. The largest open source project is Chromium, led by Google, which serves as the core of various web browsers. Unexpectedly, Microsoft announc...

摘要：We find the death of distance in venture capital (VC) investment caused by the COVID-19 pandemic: VCs invest in more distant startups during the COVID-19 lockdowns, and such effects continue after the economy reopens. The death of distance is more pronounced when there is better internet infrastructure, lower information asymmetry between VCs and entrepreneurs, and smaller deal size. The pandemic-spurred advancement and adoption of remote communication technology contribute to the documented o...

摘要：We find that boardroom centrality increases the market beta of firms. The higher stock returns of firms with high boardroom centrality diminish and turn statistically insignificant after controlling for market betas. The effect can be attributed to a comovement in accounting fundamentals and financial policies. Overall, these findings highlight the fact that the social networks of corporate leaders (i.e., directors of corporate boards) can have a substantial effect on firms' systematic risk ex...

摘要：Recent regulatory discussions concentrate on the role institutional investors play in the financial sector. We investigate the determinants and consequences of institutional ownership (IO) in banks. Our findings suggest that institutional owners invest more in banks that have a lower proportion of consumer and real estate loans; are less opaque; have a lower level of insider control; are larger, older, and more capitalized; and have lower stock return volatility. In contrast, banks' funding ch...

摘要：This paper proposes a portfolio-independent method to estimate q-theory models, in which parameters are obtained using Bayesian Markov chain Monte Carlo (MCMC) to match firm-level stock returns. Our methodology addresses a previous critique on prior studies that model parameters are chosen to fit a specific set of anomalies and different values are needed to fit each anomaly. By targeting the entire sample of firm-level returns and allowing industry and time variations in parameter values, our...

摘要：Innovation contests incentivize the participants' to exert effort toward combining (recombining) their existing knowledge to create solutions. In the current work, we consider the case of serial contests, where effort to create solutions for earlier contests can also expand the participant's knowledge, which can then be valuable in future contests. We develop a novel framework that explicitly includes the generation and utilization of knowledge by participants in knowledge-driven serial innova...

摘要：Experimentation is increasingly used across domains such as healthcare and online platforms to inform decision making, with a central goal often being the estimation of the average treatment effect (ATE). However, in many real-world settings, treatment effects, or even the treatments themselves, evolve over time, making classical experimental designs, which assume stationarity, less effective or even misleading. This paper studies nonstationary experimental design under structured trends, addr...

摘要：The share-of-choice product design problem is to find the product, as defined by its attributes, that maximizes market share arising from a collection of customer types or segments. When customers follow a logit model of choice, the market share is given by a weighted sum of logistic probabilities, leading to the logit-based share-of-choice product design problem. In this paper, we develop a methodology for solving this problem to provable optimality. We first analyze the complexity of this pr...

摘要：People sometimes enjoy the thrill of the hunt, which implies search can generate joy in addition to costs. Some customers say they enjoy searching for unique items such as vintage T-shirts and luxury handbags, and managers at warehouse stores, thrift stores, and many online selling platforms say they design their store format to offer a treasure hunt experience. We develop a model in which customers enjoy searching for a treasure. Our model's search utility function includes a term based on th...
