We exploit within-school variation in counselors and find that one additional counselor reduces student misbehavior and increases boys’ academic achievement by over one percentile point. These effects compare favorably with those of increased teacher quality and smaller class sizes. 相似文献

We make the point that preferences for democracy are positively correlated with level of education. This correlation is robust even after controlling for a range of personal characteristics, including country of residence, income, age, or using different definitions of preferences for democracy or using instrumental variables. Interestingly, the results hold across countries with different level of democracy. We use data from World Values Surveys and show that our results are consistent with a simple theoretical model in which education makes political accountability easier. 相似文献

The Roles of Sustainability Orientation and Market Knowledge Competence in New Product Development Success 下载免费PDF全文
Marius C. Claudy Mark Peterson Mark Pagell 《Journal of Product Innovation Management》2016,33(Z1):72-85
Firms’ sustainability orientation (SO) is widely understood as a strategic resource, which can lead to competitive advantage and superior (financial) performance. While recent empirical evidence suggests a moderate and positive relationship between SO and financial performance on a corporate level, little is understood about the influence of SO on new product development (NPD) success. Building on the natural‐resource‐based view (NRBV) of the firm, we hypothesize that firms’ SO positively influences NPD success, because of efficiency gains and differentiation advantages. However, scholars have also argued that the win–win paradigm postulated by NRBV might not always hold because NPD managers might find it difficult to balance sustainability objectives with the needs of their customer and the competitive dynamics in their markets. It is, therefore, proposed that market knowledge competence (MKC) is an important capability, which helps firms to balance social and ecological objectives with economic goals such as profitability and market share. Using data from 343 international firms from 24 countries that was collected by the Product Development and Management Association, structural equation modeling results suggest that (1) SO positively influences NPD and that (2) this relationship is partially mediated by firms’ market knowledge capabilities. The findings suggest that strategic‐level SO and MKC are complementary in that they help in balancing trade‐offs between sustainaility objectives and profitability goals. In this way, the study contributes to a better understanding of how critical NPD practices can help managers to translate firms’ SO into NPD success. The article concludes by highlighting implications for product innovation managers. 相似文献

This paper explores the theoretical underpinnings of collaboration and ecosystem management in order to identify the relationships and processes involved in implementing ecosystem management programs through cross‐sector collaboration. Ecosystem management requires a highly adaptive and resilient social–ecological governance approach, which addresses spatiality and temporality issues. In order to explore possible implementation issues with ecosystem management, propositions are developed dealing with adaptive governance, institutional isomorphism and collective action. The paper concludes with a discussion of the theoretic underpinnings involved in implementing ecosystem management through cross‐sector collaborations.

ABSTRACTThis article investigates how a firm's financial strength affects its dynamic decision to invest in R&D. We estimate a dynamic model of R&D choice using data for German firms in high-tech manufacturing industries. The model incorporates a measure of the firm's financial strength, derived from its credit rating, which is shown to lead to substantial differences in estimates of the costs and expected long-run benefits from R&D investment. Financially strong firms have a higher probability of generating innovations from their R&D investment, and the innovations have a larger impact on productivity and profits. Averaging across all firms, the long-run benefit of investing in R&D equals 6.6% of firm value. It ranges from 11.6% for firms in a strong financial position to 2.3% for firms in a weaker financial position. 相似文献

This study examines whether CEO duality affects the association between board independence and demand for higher quality audits, proxied by audit fee. The findings show that there is a positive association between board independence and audit fees. This result is consistent with findings of Carcello et al. (2002) that more independent boards demand higher audit quality and effort. However, this positive association is only present in firms without CEO duality, thus suggesting that CEO duality constrains board independence. The results support recommendations against CEO duality by showing that dominant CEOs may compromise the independence of their board of directors. Additionally, evidence is provided that board size (the number of directors on the board) is positively associated with audit fee pricing. This is consistent with prior studies that indicate that larger board sizes are associated with inefficiency and negative firm performance. 相似文献
