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

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

Scholars and policymakers interested in the growth and prosperity of regions have long recognized that talent and knowledge are fundamental. Yet the question is what types of talent are needed in a growing twenty‐first‐century economy: human capital, creativity and innovation, or entrepreneurship? The latter we define broadly to include any type of risk taking, and not only radical innovation. The literature does not clearly point to one factor as being the most essential. This study assesses this question separately for rural and urban United States (US) counties. We find that human capital––measured by educational attainment––is considerably more conducive to employment growth than the share of creative occupations. Likewise, the share of small and medium businesses is also very conducive to local growth, although this does not apply to the self‐employment share. Rural and urban areas experience similar patterns, although the magnitude thereof tends to be larger for urban counties, whereas high‐technology employment share has had a positive effect in rural areas. Policy conclusions suggest that enhancing small business development and increasing educational attainment are the two strategies that are most likely to succeed.  相似文献

Gold and the US dollar: Hedge or haven?   总被引:1,自引:0,他引:1  
Using a model of dynamic conditional correlations covering 23 years of weekly data for 16 major dollar-paired exchange rates, this paper addresses a practical investment question: Does gold act as a hedge against the US dollar, as a safe haven, or neither? Key findings are as follows. (i) During the past 23 years gold has behaved as a hedge against the US dollar. (ii) Gold has been a poor safe haven. (iii) In recent years gold has acted, increasingly, as an effective hedge against currency risk associated with the US dollar.  相似文献

This paper offers new insights into Beveridge curve analysis by modelling the unemployment–vacancy rate relationship within a Markov regime‐switching environment in which the probabilities of curve‐shifting are determined endogenously by shift factors. Shift factors include structural factors such as labour market participation and net migration, while cyclical variables include GDP growth, the real rate of interest, and labour productivity. This approach enables us to estimate regime‐specific parameters and to assess the role played by these factors in influencing the transition probabilities of switching between regimes. Using New Zealand data, we show that increases in the participation rate have shifted the Beveridge curve inward, while increases in net migration have shifted the curve outward.  相似文献

While decision makers in organizations frequently make good decisions rooted in stable and consistent preferences, such consistency in outcomes is not always the case. In this study, we adopt a psychological perspective of judgment to investigate managers' erratic strategic decisions, which we define as a manager's inconsistent judgments that can shape the direction of the firm. In a study of 2,048 decisions made by 64 CEOs of technology firms, we examine how both metacognitive experience and perceptions of the external environment (hostility and dynamism) could affect the extent to which managers make erratic strategic decisions. The results indicate that managers with greater metacognitive experience make less erratic strategic decisions. The results also indicate that in hostile environments managers make more erratic strategic decisions. But contrary to our expectations, in dynamic environments managers make less erratic strategic decisions. Similarly, hostility and dynamism interact in their effect on erratic strategic decisions in that the positive relationship between environmental hostility and erratic strategic decisions will be less positive for managers experiencing high environmental dynamism than those experiencing low environmental dynamism. These results have important implications for strategic decision‐making research. Copyright © 2010 John Wiley & Sons, Ltd.  相似文献
