This paper tests the efficiency hypothesis of the knowledge spillover theory of entrepreneurship. Using a comprehensive database for 63 countries for 2012, we employ data envelopment analysis to directly test how countries capitalize on their available entrepreneurial resources. Results support the efficiency hypothesis of knowledge spillover entrepreneurship. We find that innovation-driven economies make a more efficient use of their resources, and that the accumulation of market potential by existing incumbent businesses explains country-level inefficiency. Regardless of the stage of development, knowledge formation is a response to market opportunities and a healthy national system of entrepreneurship is associated with knowledge spillovers that are a prerequisite for higher levels of efficiency. Public policies promoting economic growth should consider national systems of entrepreneurship as a critical priority, so that entrepreneurs can effectively allocate resources in the economy. 相似文献

Immigration is profoundly changing the racial demographics of America. In this article, we seek to understand if and how immigration and increasing racial diversity are shaping the partisan politics of individual white Americans. We show that whites’ views on immigration and Latinos are strongly related to their core political identities and vote choices. Using a range of different surveys, we find that, all else equal, whites with more anti‐immigrant views or more negative views of Latinos are less apt to identify as Democrats and less likely to favor Democratic candidates. This rightward shift harkens back to an earlier period of white defection from the Democratic Party and highlights the enduring but shifting impact of race on American politics. 相似文献

The article presents an intelligence case gone bad during the Second World War, when the United States decided to drop a three-man OSS group into Hungary. Hungary, a close ally of Germany, after seeing that the war was not going to end with an Axis victory, wished to seek contact with the Western Allies in order to try to find a way out of its precarious situation. The study, based mainly on archival research, shows the evolution of the Sparrow Mission, whose goals are still unclear today. Both the preparations and the timing of the mission seem to indicate that the plan had some influence on the German decision of occupying Hungary in March 1944, and such a German move helped the Normandy landing of the Allies a few months later. 相似文献

Women earn less than men who work in the same job with the same level of experience. We know much about this gender wage gap but relatively little about its political or partisan sources. In this article, we examine the effects of party control of state government on gender inequality in income, wages, unemployment, and poverty. Employing both a regression discontinuity design and a dynamic difference‐in‐difference analysis, we find that electing a Democratic majority to the state house leads to substantial improvement in women's incomes, wages, and unemployment relative to men—especially in recent years. We also show that greater female representation in office and more liberal policymaking on policies related to women's rights could be driving that process. We find, however, fewer clear effects on poverty and less robust results for partisan control of the governor's office or the state senate. Parties and politics matter, but not always. 相似文献
