This study estimates the price effects of horizontal mergers in the U.S. grocery retailing industry. We examine fourteen regions affected by mergers, including mergers in highly concentrated and relatively unconcentrated markets. We identify price effects by comparing markets affected by mergers to unaffected markets using difference‐in‐difference estimation with three different comparison groups, propensity score weights, and by using the synthetic control method. Our results are robust to the choice of control group and estimation technique. We find that mergers in highly concentrated markets are most frequently associated with price increases, and mergers in less concentrated markets are most often associated with price decreases.  相似文献

Research Summary: While prior studies have predominantly shown that CEO narcissism and hubris exhibit similar effects on various strategic decisions and outcomes, this study aims to explore the mechanisms underlying how narcissistic versus hubristic CEOs affect their firms differently. Specifically, we investigate how peer influence moderates the CEO narcissism/hubris—corporate social responsibility (CSR). With a sample of S&P 1500 firms for 2003–2010, we find that the positive relationship between CEO narcissism and CSR is strengthened (weakened) when board‐interlocked peer firms invest less (more) intensively in CSR than a CEO's own firm; the negative relationship between CEO hubris and CSR is strengthened when peer firms are engaged in less CSR than a CEO's own firm. Managerial Summary: Some CEOs are more narcissistic while others may be more hubristic, but these two groups of CEOs hold different attitudes toward the extent to which their firms should engage in corporate social responsibility (CSR). Our findings with a large sample of U.S. publically listed firms suggest that narcissistic CEOs care more about CSR, but hubristic CEOs care less. Interestingly, when narcissistic CEOs observe their peer firms engaging in more or less CSR than their own firms, they tend to respond in an opposite manner; in contrast, hubristic CEOs will only engage in even less CSR when their peers also do not emphasize CSR. Our findings point to a fundamental difference between CEO narcissism and hubris in terms of how they affect firms' CSR decisions based on their social comparison with peer firms.  相似文献

This study analyzes the effect of variety on consumer utility using historical behavioral information for 1,397 consumers participating in 729,049 unique rounds of play. We show that consumers generally exhibit a preference for variety as part of their gameplay utility. The relationship between variety and utility is nonlinear and follows, at least for some types of variety, an inverted u‐shape as predicted by the Wundt curve. Our results represent the first such evidence on the importance of variety in video gaming, which has significant implications for consumption through optimization of gameplay utility to satisfy the demand for variety.  相似文献

The purpose of this research reflection is to set the stage for a more detailed research agenda in exploring event sport tourism experiences of support partners (SPs) during events. Using photo elicitation, the article presents a preliminary empirical case study. Visual materials were assembled by three female participants to interrogate how SPs experience “spectator space” and explore the processes that produced those experiences, an area of study that remains relatively unexplored in leisure research. Initial findings show how waiting to see the triathlete can be anxiety-provoking, but the release of emotion when smiles are exchanged constitutes core activities of being there. However, there are more questions than answers, and there is a need for further inquiry. Suggestions for future research on the impact of serious leisure on intimate others are given.  相似文献

We examine how mergers affect quality provision by analyzing five U.S. airline mergers, focusing on on‐time performance (OTP). We find that airline mergers have minimal negative impacts on OTP, and likely result in long‐run improvements due to efficiencies. Importantly, we show that this finding is not driven by post‐merger changes in price that could affect OTP. Consequently, at least in the case of airlines, policymakers should not, as a rule, fear the negative quality effects of mergers.  相似文献

I show that the benefit of a high reserve price in a common‐values ascending auction is lower than in the observationally equivalent private values setting. Put another way, when bidders have common values, empirical estimation based on a private‐values model will overstate the value of a high reserve price. Via numerical examples, I show this same ranking typically applies to the level of the optimal reserve price as well, and often to the benefit of any reserve price, not just high ones. With common values, the optimal reserve can even be below the seller's valuation, which is impossible with private values.  相似文献

The legal framing of a firm’s pricing strategy can determine whether it constitutes online resale price maintenance (RPM) or online most favored nation (MFN). Together, cases that involve online RPM and MFN can be viewed as a natural experiment of how antitrust economics and law may adapt to an online world. Thus far, legal theories that have been inconsistent with economic theories have dictated enforcement across jurisdictions, which has led to confusion that thwarts potentially efficient business practices. This paper distinguishes issues of online RPM from traditional RPM and online RPM from online MFN. We apply the economics learning to RPM and analyze the antitrust cases of online RPM and MFN to date in the United States, Europe, and Australia. Finally, we offer policy recommendations that reduce the confusion in current legal doctrine.  相似文献

Texas is one of the most popular states for tourists. Using quantitative and primarily qualitative methods, we analyzed how marketers of small cities and towns associate their place to four central components of the Texas state narrative – the flag, official and unofficial symbols, territory, and social–historical mythology – in advertising and tourism brochures in the years 2008–2010. We discovered that in parallel to the overuse of the “associating to well-known brand/narrative” strategy, marketers also invest efforts toward claiming the narrative. Thus our second goal was to discover which techniques were used in order to claim the state narrative. Using the state of Texas as an example may provide a test case for typology, associating and claiming state narratives in promotional materials.  相似文献
