摘要：Marital status can both reflect and affect individual preferences. We explore the impact of marriage on corporate chief executive officers (CEOs) and find that firms run by single CEOs exhibit higher stock return volatility, pursue more aggressive investment policies, and do not respond to changes in idiosyncratic risk. These effects are weaker for older CEOs. Our findings continue to hold when we use variation in divorce laws across states to instrument for CEO marital status, which supports ...

摘要：The popularity of New Year's resolutions suggests that people are more likely to tackle their goals immediately following salient temporal landmarks. If true, this little-researched phenomenon has the potential to help people overcome important willpower problems that often limit goal attainment. Across three archival field studies, we provide evidence of a fresh start effect. We show that Google searches for the term diet (Study 1), gym visits (Study 2), and commitments to pursue goals (Study...

摘要：Organization theory highlights the spread of norms of rationality in contemporary life. Yet rationality does not always spread without friction; individuals often act based on other beliefs and norms. We explore this problem in the context of restaurants and diners. We argue that consumers potentially apply either of two social codes when forming value judgments about restaurants: (1) an apparently rational science-based code of hygiene involving compliance with local health regulations or (2)...

摘要：I show that turnover is unrelated to several alternative measures of liquidity risk and in most cases negatively, not positively, related to liquidity. Consequently, neither liquidity nor liquidity risk explains why higher turnover predicts lower future returns. I find that the aggregate volatility risk factor explains why higher turnover predicts lower future returns. This paper shows that the negative relation between turnover and future returns is stronger for firms with option-like equity,...

摘要：A key concern about counterfeits and weak intellectual property protection is that they may hamper innovation by displacing legitimate sales. This paper combines a natural policy experiment with randomized lab experiments to estimate the heterogeneous impacts of counterfeiting on the sales and consumer purchase intent related to branded products of various quality levels. I collect new product-line-level panel data (1993-2004) on Chinese shoe companies. I identify heterogeneous effects of coun...

摘要：This paper studies the impact of an electronic medical record (EMR) system on the productivity of physicians. Physicians influence a vast majority of treatment decisions and are central to the care delivery process; thus, it is important to understand how EMRs may impact the nature of their work. Our research builds on prior literature on physician productivity, IT productivity, and task-technology fit theory. We use a unique panel data set comprising 87 physicians specializing in internal med...

摘要：We consider the problem of choosing, from a set of N potential stock-keeping units (SKUs) in a retail category, K SKUs to be carried at each store to maximize revenue or profit. Assortments can vary by store, subject to a maximum number of different assortments. We view a SKU as a set of attribute levels and also model possible substitutions when a customer's first choice is not in the assortment. We apply maximum likelihood estimation to sales history of the SKUs currently carried by the reta...

摘要：Whether and how trust and trustworthiness differ between a collectivist society, e. g., China, and an individualistic one, e. g., the United States, generates much ongoing scientific debate and bears significant practical values for managing cross-country transactions. We experimentally investigate how supply chain members' countries of origin-China versus the United States-affect trust, trustworthiness, and strategic information sharing behavior in a cross-country supply chain. We consider a ...

摘要：T his paper studies the effect of limited information in a sequential search setting where a single selection is to be made from a set of random potential options. We consider both a full-information problem, where the decision maker observes the exact value of each option as she searches, and a partial-information problem, in which the decision maker only learns the rank of the current option relative to the options that have already been observed. We develop a model that allows for a sharp c...
