摘要：Many social scientists have assumed that people's preferences can be described by stable and coherent utility functions. This notion of stable utility functions has been challenged by cognitive psychologists who suggest that preferences are malleable and constructed in the moment, but neither camp has explained how the subjective valuations underpinning preferences arise. One influential attempt to do so is the Decision by Sampling (DbS) model, which suggests that a quantitative attribute's (e...

摘要：Expert opinion exerts tremendous influence on the purchase journey, but its effect on overall consumer experience is ambiguous because it can give rise to both expectation and reputation effects. This paper explores the effect of expert opinions on consumer experience via the lens of consumer reviews in the restaurant industry, where the expert opinions are conveyed by Michelin stars. The paper uses a unique data set based on the Michelin Guide for Great Britain & Ireland from 2010 to 2020. Th...

摘要：We examine the relation between temperature changes and firm performance using a novel time-varying measure of firm-level temperature sensitivity. We find that firms with higher temperature sensitivity have lower future profitability and riskier corporate policies. These firms are also overpriced and earn lower average future returns as market participants are slow to correct the mispricing. Nonlocal institutional investors allocate higher portfolio weights to firms with high temperature sensi...

摘要：This paper explores whether and how consumers respond to global social movements challenging systemic discrimination and stereotypes. We examine the impact of the #MeToo movement on the market for products with stereotypical markers of femininity. Our analysis of high-frequency stockout and price data from a leading global fashion retailer spans from January 2017 to December 2018 and covers 32 countries, or 89% of the Organization for Economic Cooperation and Development (OECD) population. Usi...

摘要：A mixture of multinomial logits (mixed multinomial logit (MMNL)) generalizes the multinomial logit model, which is commonly used in modeling market demand to capture consumer heterogeneity. Although extensive algorithms have been developed in the literature to learn MMNL models, theoretical results are limited. Built on the Frank-Wolfe (FW) method, we propose a new algorithm that learns both mixture weights and componentspecific logit parameters with provable convergence guarantees for an arbi...

摘要：We propose a new optimization-based method for learning causal structures from observational data, a process known as causal discovery. Our method takes as input observational data over a set of variables and returns a graph in which causal relations are specified by directed edges. We consider a highly general search space that accommodates latent confounders and feedback cycles, which few extant methods do. We formulate the discovery problem as an integer program, and propose a solution tech...

摘要：Leading retailers have opened up their online storefronts to competitors by operating marketplaces for third-party sellers. We develop a model of entry and price competition at the product market level to analyze the competitive interactions arising within these retailer-led marketplaces. We show that the retailer benefits from the marketplace by mitigating his own capacity constraints and manages competition from third-party sellers through his control of the storefront: by setting the market...

摘要：Data analytics enable firms to offer personalized prices to targeted consumers but at a cost. We study a competitive personalized pricing game where the entrant is uncertain about the incumbent's targeting cost. We demonstrate that implementing personalized pricing through a list price-discount scheme allows the incumbent to signal its targeting cost via the list price. This signaling mechanism is effective because the list price serves as a price ceiling, which limits the incumbent's ability ...

摘要：Variation in functional expertise is an important decision that managers face when designing teams tasked with being creative. We develop theory that predicts that functional diversity has countervailing effects on team creativity through its positive (negative) effect on the uniqueness (usefulness) of the proposals generated. We conduct an experiment where functionally homogeneous or heterogeneous two-person teams are tasked with proposing a creative use for an unused university space. We mea...

摘要：Randomized experiments with treatment and control groups are an important tool to measure the impacts of interventions. However, in experimental settings with onesided noncompliance extant empirical approaches may not produce the estimands a decision maker needs to solve the problem of interest. For example, these experimental designs are common in digital advertising settings but typical methods do not yield effects that inform the intensive margin: how many consumers should be reached or how...
