In a model with fixed cost of price adjustment and idiosyncratic shocks, two parameterizations match a large set of microeconomic facts, yet display different degrees of nonneutrality. Although there is substantial nonneutrality in both cases, the model does not behave like a time-dependent model, as changes in the distribution of firms account for roughly a third of the short-run response of the price level to a monetary shock. We use the model to examine how aggregating firm behavior can generate flat hazards; we also find that a recently developed steady-state statistic is an imperfect guide to characterizing nonneutrality. 相似文献
In this paper, we propose a new unrelated question model for estimating the prevalence of a sensitive characteristic within a population by utilizing two decks of cards. The resultant estimator is then compared to its competitors as to efficiency and as to protection of respondents. A real data application analyzing e-cigarette use among college students is considered. 相似文献
We study the impact of Quickpay, a reform that permanently accelerated payments to small business contractors of the U.S. government. We find a strong direct effect of the reform on employment growth at the firm level. However, we document substantial crowding out of nontreated firms' employment within local labor markets. While the overall net employment effect is positive, it is close to zero in tight labor markets. Our results highlight an important channel for alleviating financing constraints in small firms, but emphasize the general-equilibrium effects of large-scale interventions, which can lead to lower aggregate outcomes depending on labor market conditions. 相似文献
The health spending slowdown associated with the managed care revolution in the 1990s suggests that managed care may have been successful in controlling health care spending. I exploit the passage of state regulation during the “managed care backlash” as well as geographic variation in managed care intensity to measure the impact of managed care on spending. I find that restricting managed care causes a large and significant increase in hospital spending, which cannot be explained by changes in hospital market concentration, other regulatory activity, and multiple other possible explanations. I also do not find effects of the backlash on mortality. 相似文献
We propose and estimate a spatially aggregated discrete-choice model with overlapping consumer choice sets and demographic-driven heterogeneity that varies by chain. Our approach avoids the need to define markets ex ante and captures rich substitution patterns, even in the absence of price data. An application to the US grocery industry illustrates the importance of location, format, and the spatial distribution of consumers in shaping the competitive environment. Contrary to conventional wisdom, we find substantial cross-format competition between supercenters, clubs, and traditional grocers. Finally, we evaluate two representative mergers between supermarket chains to demonstrate how our estimates inform antitrust policy. 相似文献

This editorial addresses one of the greatest challenges of our time—racial inequality. Logistics and supply chain management (SCM) factor prominently in people’s everyday experiences, as consumers of products and logistics services as well as through participation in logistics and supply chain workforces. These everyday experiences can be quite disparate depending on one’s race. As academics, we have a responsibility to peel back the layers of how these issues of race and diversity impact and interact with supply chain phenomena. This editorial is intended to bolster conversation around these issues. We identify compelling themes that merit consideration and, perhaps, deeper investigation, including race as an individual difference variable in our research, race in SCM talent and leadership, and race and racism in SCM execution. We also call for more research that addresses racial inclusion and equal access in other aspects of SCM in light of its far-reaching influence in the realms of business and society. The time has come to address these pervasive issues affecting organizations and individuals. We also introduce the articles appearing in the current issue of the journal. 相似文献

University business incubators (UBIs) are an important part of the ecosystem that supports entrepreneurial activities and economic development. Extant research has focused on examining UBI activities at a single point in time, but there is a paucity of theoretical and empirical work aimed at understanding the forces that explain why and how UBIs change over time. This is an important gap because establishing a university business incubator does not assure its development and growth. We address this issue by drawing upon the Fisher et al. Academy of Management Review, 41(3), 383-409 (2016) Identity-Legitimacy-Life Cycle model to explain how the pursuit of resources and organizational legitimacy shapes the development of UBIs along key strategic and operational dimensions, which has implications for performance evaluation over time. We illustrate with a case study about the creation and evolution of the DMZ, a leading UBI at Ryerson University in Canada. This case provides new insights about the dynamics of UBIs and their relationships with the entrepreneurial ecosystems in which they are embedded. Implications for future research, management practice, and public policy are discussed.
