摘要：Fund companies regularly send shareholder letters to their investors. We use textual analysis to investigate whether these letters' writing style influences fund flows and whether it predicts performance and investment styles. Fund investors react to the tone and content of shareholder letters: a less negative tone leads to higher net flows. Thus, fund companies can use shareholder letters as a tactical instrument to influence flows. However, at the same time, a dishonest communication that is...

摘要：Revenue management decisions often involve both offline and online decisions. Offline decisions are made first and establish the broad and long-term operational context in which online decisions are frequently and repeatedly made, often in real time. We consider a joint optimization of offline and online decisions. Specifically, we examine a setting in which the offline decision concerns the selection of product-design characteristics (e.g., price, capacity, return eligibility, and other chara...

摘要：We estimate the size of the likely unofficial income of the government official household by assessing the difference between the income necessary to explain their observed home purchase behavior and the official income. Using unique and comprehensive House Provident Fund and home purchases data between 2006 and 2013 in a large Chinese city, we reach three conclusions. First, an average official's unofficial income is 83% of her official income; this percentage increases sharply with the offic...

摘要：Amid the rise of the influencer economy, fake social media accounts have become prevalent on many social media platforms. Yet the problem of fake accounts is still poorly understood, and so is the effectiveness of coping strategies. This research models the ecosystem of fake accounts in an influencer economy and obtains insights on fake account purchasing behaviors, the impact of antifake efforts, and the roles of various contextual factors. We show that as the antifake effort increases, the e...

摘要：A critical element of word of mouth (WOM) or buzz marketing is to identify seeds, often central actors with high degree in the social network. Seed identification typically requires data on the relevant network structure, which is often unavailable. We examine the impact of WOM seeding strategies motivated by the friendship paradox, which can obtain more central nodes without knowing network structure. Higher degree nodes may be less effective as seeds if these nodes communicate less with neig...

摘要：The predominant focus of the organizational literature on trust has been on direct interactions between actors. Whereas this emphasis has solidified our understanding of the dyadic foundations of trust, we know relatively little about the mechanisms of trust creation in network contexts. In this paper, we introduce the network mechanism of prismatic trust to explain why some actors are more trusted than others. Specifically, we posit that networks act as prisms that generate signals of trustwo...

摘要：Because of various factors (such as a lack of adequate statistical knowledge or data, unforeseen weather events), the yields of agricultural products often exhibit a high level of ambiguity. When facing distributional ambiguity in yields, farmers and landowners may base their contracting decisions on descriptive statistics, such as the mean and variance. To investigate how limited information could reshape optimal contract forms, we consider an agricultural supply chain in which a landowner co...

摘要：I develop an analytical model to examine the effect of disclosure on organizational structure. In this model, an owner with two investment projects decides whether to organize them as a single multidivisional firm or two stand-alone firms whose manager(s) may issue a truthful but costly disclosure of each project's profitability to raise capital. In a multidivisional firm, capital is initially provided by investors and subsequently allocated across the two projects by the manager. The analysis...

摘要：We consider a model of innovation that distinguishes between ideas and innovations. Although innovation responds to incentives, ideas are a scarce resource that provides an exogenous constraint on the rate of innovation. We investigate how the optimal reward structure is shaped by the scarcity of ideas. Substitute ideas for innovation in the model arrive to random recipients at random times. By forgoing investment in a current idea, society preserves an option to invest in a better idea for th...
