摘要：We propose an approach to model assortment optimization problems based on two observations we made from customer browsing history on Taobao. First, most customers consider very few items (no more than five) before purchasing. Second, there exists a sorting of items so that most customer consideration sets are contained in small intervals in this sorting. This sorting can be discovered by the Cuthill-McKee algorithm, which is designed to work with sparse matrices. We encode these two observatio...

摘要：Firm births are key drivers of employment growth, productivity gains, and creative destruction. We show that setup costs create sizable financial constraints for new firms. When firms face high setup costs, they can only be established by leveraging up and lengthening debt maturity. We empirically confirm these predictions in a large sample of young French firms. Leverage is higher and debt maturity is longer in industries with high setup costs. Last, we show that following an exogenous shock ...

摘要：We document the disconnect between earnings expectations as captured in stock prices and the ultimate realization of earnings over long periods. To do so, we compare firms' stock prices on the first trading day and the beginning of each year to the realized earnings over their remaining lifetime (RLTEP ratio). We document that the RLTEP ratio, averaged over long periods and over 15,000 U.S. domestic public firms, approximates one, suggesting that expectations match actuals in the aggregate. Ho...

摘要：Price distortions created by so-called pump-and-dump schemes are well documented, but relatively little is known about the investors in these schemes. By examining 470 pump-and-dump schemes and a large data set of trading records for over 110,000 individual investors from a major German bank, we provide comprehensive evidence on the participation rate, the magnitude of the investments, the losses, and the characteristics of the individuals who invest in such schemes. Participation is quite com...

摘要：I study the influence of tax deductibility on decisions to defer executive compensation by exploiting a plausibly exogenous tax change that increases the deductibility of the chief financial officer's (CFO's) nonperformance-based compensation, with no impact on the nontax determinants of deferrals. Using a difference-in-differences research design, I find that CFO deferred compensation significantly decreases after the tax change, relative to the deferrals of the chief executive officer (CEO) ...

摘要：In order to build a successful new product development (NPD) portfolio, a firm must ensure not only its access to a wide variety of candidate NPD projects but also its capacity to collect and verify vital information about these projects prior to project selection. In practice, a popular strategy to enrich the set of candidate projects is to contemplate investing in both internal and external NPD projects; however, this approach often interferes with the firm's ability to evaluate its own proj...

摘要：Employees routinely make valuable contributions at work that are not part of their formal job description, such as helping a struggling coworker. These contributions, termed organizational citizenship behavior, are studied from many angles in the organizational behavior literature. However, the degree to which the past helping behavior of employees scheduled to a shift impacts that shift's operational outcomes remains an underexplored question. We define two measures of past helping behavior f...

摘要：Choice models, which specify the consumers' choice probabilities of options over a given choice set, are widely studied and applied in many fields. We propose a temporal tree representation of choice that covers all rational choice models. Compared with existing structural choice models, the tree representation exhibits two major advantages that address the key challenges of model identification. First, all rational choice models have a tree representation, and a subclass of tree representatio...

摘要：We study electric vehicle (EV) fleet and charging infrastructure planning in a spatial setting. For a centrally managed fleet that serves customer requests arriving continuously at a rate lambda throughout the day, we determine the minimum number of vehicles and chargers for a target service level along with matching and charging policies. Whereas non-EV systems require extra Theta(lambda 2/3) vehicles because of pickup times, EV systems differ. Charging increases nominal capacity, enabling pi...
