摘要：The most commonly cited issues with mobile apps are low user engagement and retention levels. In this paper, we use a randomized control trial to test the efficacy of crowdsourcing on enhancing user engagement and retention in the context of mobile gaming apps. We examine two specific crowdsourcing features: the ability to submit content and the ability to access crowdsourced content. We find that the content submission significantly increases engagement and retention by reducing users' hazard...

摘要：To capture the dynamics of idiosyncratic volatility of stock returns over different horizons and investigate the relationship between idiosyncratic volatility and expected stock returns, this paper develops and estimates a parsimonious model of idiosyncratic volatility consisting of a short-run and a long-run component. The conditional short-run and long-run components are found to be positively and negatively related to expected stock returns, respectively. The positive relation between the s...

摘要：In a randomized controlled trial, a large retail chain's Chief Executive Officer (CEO) sets new goals for the managers of the treated stores by asking them to do what they can to reduce the employee quit rate. The treatment decreases the quit rate by a fifth to a quarter, lasting nine months before petering out, but reappearing after a reminder. There is no treatment effect on sales. Further analysis reveals that treated store managers spend more time on human resources (HR) and less on custom...

摘要：A decision maker (DM) must choose an action in order to maximize a reward function that depends on the DM's action as well as on an unknown parameter T. TheDM can delay taking the action in order to experiment and gather additional information on T. We model the problem using a Bayesian sequential experimentation framework and use dynamic programming and diffusion-asymptotic analysis to solve it. For that, we consider environments in which the average number of experiments that is conducted pe...

摘要：This paper examines whether information extracted via text-based statistical methods applied to employee reviews left on the website Glassdoor.comcan be used to develop indicators of corporate misconduct risk. We argue that inside information on the incidence of misconduct as well as the control environments and broader organizational cultures that contribute to its occurrence are likely to be widespread among employees and to be reflected in the text of these reviews. Our results show that in...

摘要：We study optimal advertising and entry timing decisions for a new product being sold in two-segment markets in which followers are positively influenced by elites, whereas elites are either unaffected or repulsed by product popularity among followers. Key decisions in such markets are not only how much to advertise in each segment over time but also when to enter the follower segment. We develop a continuous-time optimal control model to examine these issues. Analysis yields two sets of two-po...

摘要：Although extant literature investigates the role of sell-side equity analysts in capital markets, most studies do not consider that sell-side equity analysts often work in hierarchical teams. Lead analysts manage a team of associate and junior analysts who participate in the team's tasks. Building on the delegation theory in the management literature, we hypothesize and find a division of labor between lead and associate analysts, where lead analysts are more likely to delegate tasks (1) that ...

摘要：We study intraday, market-wide shocks to stock prices, market liquidity, and trading activity on international stock markets and assess the relevance of recent theories on liquidity dry-ups in explaining such shocks. Market-wide price shocks are prevalent and large, with rapid spillovers across markets. However, price shocks are predominantly driven by information; they do not revert and are often associated with macroeconomic news. Furthermore, liquidity shocks are typically isolated and tran...

摘要：Socialmovements have the potential to effect change in strategic decisionmaking. In this paper, we examine whether the #MeToo movement, spurred by the Harvey Weinstein scandal, leads to changes in the likelihood of Hollywood producers working with female writers on new movie projects. Because #MeToo affected the entire industry, we use variation in whether producers had past collaborations with Weinstein to investigate whether and how #MeToo may spur change. We find that producers previously a...

摘要：We consider dynamic repositioning when competing firms try to follow the evolution of consumer preferences while taking into account the competitive interaction, both in terms of static market competition and the dynamic effects of different firm positionings. We fully characterize the dynamic market equilibrium, which includes the timing of the firms' repositionings depending on consumer preferences. As consumer preferences evolve away from where both firms are located, one firm first moves t...
