摘要：Although volatile marketing spending, as opposed to even-level spending, may improve a brand's financial performance, it can also increase the volatility of performance, which is not a desirable outcome. This article analyzes how revenue and cash-flow volatility are influenced by own and competitive marketing spending volatility, by the level of marketing spending, by the responsiveness to own marketing spending, and by competitive response. From market response theory, we derive propositions ...

摘要：The multiarmed bandit problem is a popular framework for studying the exploration versus exploitation trade-off. Recent applications include dynamic assortment design, Internet advertising, dynamic pricing, and the control of queues. The standard mathematical formulation for a bandit problem makes the strong assumption that the decision maker has a full characterization of the joint distribution of the rewards, and that arms under this distribution are independent. These assumptions are not sa...

摘要：Relationship lending may create benefits for borrowers by reducing information asymmetries. However, empirical evidence is mixed. We conduct a meta-analysis to summarize and explain the heterogeneity in the results in the literature using hand-collected information from 101 studies in the United States, Europe, Asia, and Latin America from 1970 to 2010. We find that strong relationships are generally beneficial for borrowers, but lending outcomes differ across the relationships' dimensions. Lo...

摘要：Viral products and ideas are intuitively understood to grow through a person-to-person diffusion process analogous to the spread of an infectious disease; however, until recently it has been prohibitively difficult to directly observe purportedly viral events, and thus to rigorously quantify or characterize their structural properties. Here we propose a formal measure of what we label structural virality that interpolates between two conceptual extremes: content that gains its popularity throu...

摘要：Using a large panel of U.S. companies, I document that firms that rely more on arm's length financing, such as public debt and equity, innovate more and have higher-quality innovations than firms that use other sources, such as relationship-based bank financing. I hypothesize that one possible reason for this finding is the greater flexibility and tolerance to experimentation associated with arm's length financing. I find support for this hypothesis by showing that firms with more arm's length...

摘要：With scarce empirical support, prior literature argues that managers tend to withhold good news and promote bad news to preserve their bargaining power against labor unions. This paper provides empirical evidence of this rarely supported argument. Using comprehensive firm-level data from South Korea, where labor unions have a long tradition of making credible threats, we find that overall disclosure frequency is negatively related to labor union strength, and that this relation is more pronoun...
