Objectives. We investigate the economic geographies of streets named for Reverend Dr. Martin Luther King, Jr. (MLK Streets), which are an increasingly common means by which various community members across the United States are attempting to commemorate the slain civil rights leader. It is our intent to characterize these negatively “branded” spaces in order to challenge some of the common perceptions about them and inform current and future MLK Street naming debates. Methods. We statistically analyze nonresidential establishments located on streets named for King in terms of scale (as measured by annual sales and employment) and industrial classification. To our knowledge, this is the first such analysis conducted at the national level. Results. Establishments located on MLK Streets do not systematically exhibit economic marginality. Establishments located on these streets do systematically exhibit unique local functions and industrial composition. Conclusion. In the absence of empirically‐driven research, the negative stereotypes that surround MLK Streets have gone unchallenged and are proliferating. The research reported here calls into question a number of these stereotypes and should inform the public, city councils, and other local policymakers, who are increasingly being faced with contentious MLK Street naming debates. 相似文献

Recent criticisms have led some to dismiss time-series analyses in the debate over the minimum wage. We investigate previous
time-series studies showing that raising the minimum wage has a smaller impact on females than males. We reanalyze the data
in light of recent developments in time-series methods and find that the minimum wage has a similar significant negative impact
on both males and females. We conclude that, following a 10 percent increase in the minimum wage, both male and female employment
drops from between 2 and 4 percent over a two-year period. This employment decrease slowly erodes as economic growth and inflation
cause the minimum wage to fall below the market-clearing wage.
We thank David Card and Alan Krueger for generously providing the data. 相似文献

Given i.i.d. observations x1,x2,x3,...,xn drawn from a mixture of normal terms, one is often interested in determining the number of terms in the mixture and their defining parameters. Although the problem of determining the number of terms is intractable under the most general assumptions, there is hope of elucidating the mixture structure given appropriate caveats on the underlying mixture. This paper examines a new approach to this problem based on the use of Akaike Information Criterion (AIC) based pruning of data driven mixture models which are obtained from resampled data sets. Results of the application of this procedure to artificially generated data sets and a real world data set are provided. 相似文献

Acquisitive growth strategies continue to be popular, in spite of increasing evidence that they often do not enhance the financial performance of acquiring firms and may adversely affect innovation. However, some acquisitions are associated with both increases in financial performance and a strengthened commitment to R&D while others experience decreases in both. Multiple theories have been offered to explain acquisitions and their outcomes, but few have received strong empirical support. This paper describes a multiple rater, multiple-case study of acquisitions that had highly favourable outcomes and others that experienced highly unfavourable outcomes. All twelve of the high performing acquisitions studied were found to exhibit the dual characteristics of friendliness during acquisition negotiations and resource complementarities between the two firms. Additionally, debt played an important role in the success (low to moderate debt) or lack of success (high or extraordinary debt) in 21 of the 24 acquisitions studied. Inadequate target evaluation was a factor in 11 of the 12 acquisitions with low performance. Importantly, the results of both sets of acquisitions suggested that a configuration of attributes affected post-acquisition performance. Other findings both supported and contradicted commonly held beliefs about acquisitions, as well as highlighted variables not typically associated with acquisition strategies. The study provides directions for future theory development and empirical research on acquisitions. 相似文献

This review of the governance practices of twenty-five public-private partnerships involved in addressing a broad range of community health needs shows that governance in public-private community partnerships departs significantly from traditional notions of institutional governance. Governance structures and degrees of progress toward governance goals vary widely and appear to be systematically related to the organization, composition, location, and activity of each partnership. 相似文献
