This paper examines the links between firm innovation and productivity using the largest cross-country panel dataset assembled for this purpose to date. We use harmonized and comparable data on a total of 40,577 small, medium and large firms surveyed in the World Bank Enterprise Surveys (WBES) and provide some support for the reported patterns previously found in the innovation literature. Our results indicate that estimates from studies using cross-section data may be upward biased but nevertheless, innovative firms are significantly and economically more productive in both the manufacturing and services sectors.  相似文献

Over the course of the 2015–2016 academic year, 12th-grade students at a Jewish high school in Canada participated in a research study that assessed how they integrated morally complex narratives in Israel’s past into their own relationship with the country. This article presents material based on how students reacted to learning that some Jewish immigrants were mistreated by the government by way of intentional economic disparity, depiction as grotesque caricatures in standard curricula, and denial of access to funds for cultural expression. The majority of students expressed shock and outrage as this narrative contrasted with the Zionist narrative that they had previously learned.  相似文献

The effect of increased development and professionalization in elite Association Football referee training and the relationship with reduced home advantage in the English professional leagues were examined. The central aim was to chart the evolution of referee training, and how these developments in referee training have assisted in reducing home advantage. Interviews were conducted with elite and ex-elite referees, as well as those involved in the management, training and administration of elite referees in order to identify more recent adaptations to elite referee training and further explain the relationship between training and the reduction in home advantage. Findings indicate training and support is pronounced within elite refereeing has developed appreciably over time, and has contributed significantly to an increase in performance, decision-making correctness and subsequent decline in home advantage.  相似文献
