摘要：A growing number of people today are participating in the gig economy, working as independent contractors on short-term projects. We study the effects of competition on gig workers??? effort and creativity on a Chinese novel-writing platform. Authors produce and sell their works chapter by chapter under a revenue-sharing or pay-by-the-word contract with the platform. Exploiting a regulation that induced a massive entry of novels in the romance genre but not other genres, we find that, on avera...

摘要：Financial constraints can cause firms to reduce product quality when quality is difficult to observe. We test this hypothesis in the context of medical choices at hospitals. Using heart attacks and child deliveries, we ask whether hospitals shift toward more profitable treatment options after a financial shock-the 2008 financial crisis. The crisis was followed by an unprecedented drop in hospital investments, yet the aggregate trends show no discrete shifts in treatment intensity post-2008. Fo...

摘要：This paper investigates the association of corporate reporting and executive network centrality, which measures an executive's relative position in a massive network consisting of outside corporate leaders. I find that high-centrality chief executive officers (CEOs) and chief financial officers (CFOs) are generally more likely to engage in financial misreporting than low-centrality CEOs and CFOs. I also find that the influence of CFO network centrality is greater than that of CEOs in financial...

摘要：Digitization has given creators direct access to consumers as well as a plethora of newdata for suppliers of new products to draw on. We study how this affects market efficiency in the context of book publishing. Using data on about 50,000 license deals over more than 10 years, we identify the effects of digitization from quasi-experimental variation across book types. Consistent with digitization generating additional information for predicting product appeal, we show that the size of license...

摘要：From business to politics and academia, the economic effects of gender quotas are under scrutiny. We provide newcausal evidence based on the introduction ofmandatory gender quotas for boards of directors of Italian listed companies. Exploiting staggered board elections, we find that quotas are associated with a new selection of board members, characterized by higher education and lower age, and no significant costs on firm performance or the stockmarket.

摘要：We consider the product-ranking challenge that online retailers face when their customers typically behave as window shoppers. They form an impression of the assortment after browsing products ranked in the initial positions and then decide whether to continue browsing. We design online learning algorithms for product ranking that maximize the number of customers who engage with the site. Customers' product preferences and attention spans are correlated and unknown to the retailer; furthermore...

摘要：We examine whether firms??? political hedging activities are effective at mitigating political risk. Focusing on the risk induced by partisan politics, we measure political hedging as the degree to which firms??? political connections are balanced across Republican and Democratic candidates. We find that greater political hedging is associated with reduced stock return volatility, particularly during periods of higher policy uncertainty. Similarly, greater political hedging is associated with ...

摘要：In the era of big data, an important weapon in a machine learning researcher's arsenal is a scalable support vector machine (SVM) algorithm. Traditional algorithms for learning SVMs scale superlinearly with the training set size, which becomes infeasible quickly for large data sets. In recent years, scalable algorithms have been designed which study the primal or dual formulations of the problem. These often suggest a way to decompose the problem and facilitate development of distributed algor...

摘要：Product reliability is a key concern for manufacturers. We examine worker turnover as a significant but underrecognized determinant of product reliability. Our study collects and integrates (1) data reporting factory worker staffing and turnover from within a major consumer electronics producer's supply chain and (2) traceable data reporting the component quality and field failures-that is, replacements and repairs-of nearly 50 million consumer mobile devices over four years of customer usage....

摘要：The cross-sectional variation in corporate profitability has occupied research across fields as diverse as strategic management, industrial organization, finance, and accounting. Prior work suggests that corporate idiosyncrasies are important determinants of profitability, but it disagrees on the quantitative importance of particular effects. This paper shows that corporate specificities become irrelevant in the long run because profitability is ergodic conditional on survival, leading to a un...
