We examine the distributional impact of large dams on cropland productivity in Africa. As our unit of analysis we use a hydrology based spatial breakdown of the continent that allows one to exactly define regions in terms of their upstream/downstream relationship at a highly disaggregated level. We then use satellite data to derive measures of cropland productivity within these areas. Our econometric analysis shows that while regions downstream benefit from large dams, no beneficial effects accrue to cropland within the vicinity. Moreover, we find that the productivity enhancing impact of upstream dams is dependent on the local climate. Overall our results suggest that upstream dams have quantitatively on average provided up to 12% of the minimum daily per capita amount of kilocalorie needs in downstream communities and increased agricultural production by 1%.  相似文献

We investigate the existence of local (within‐country) and global (between‐country) knowledge spillovers within a single analytical framework. Our study is based on a detailed database of domestically owned and foreign‐affiliated manufacturing plants located in Ireland. The results of our econometric analysis show that domestically owned plants benefit from the research and development (R&D) activities of other domestically owned plants, as well as from R&D activities conducted in the country of origin of foreign‐owned plants through their presence in Ireland. A fundamental difference between such locally generated and locally transmitted global spillovers appears to be that the latter are much less constrained by distance decay effects.  相似文献

This paper describes the first thorough empirical analysis of the pricing of leverage products in the German retail market. These mainly exchange-traded products with an impressive trading volume are frequently advertised as long and short futures contracts, although they are theoretically equivalent to one-sided barrier options. Issuers’ daily quotes for stock index products are compared to (i) theoretical values derived from the prices of Eurex options and to (ii) boundaries obtained from semi-static superhedging strategies. For the vast majority of products, bid and ask quotes significantly exceed both theoretical values and upper hedging boundaries, thus providing almost risk-free profits for the issuers.  相似文献

Martin Luther urged each town to have a girls' school so that girls would learn to read the Gospel, thereby evoking a surge of building girls' schools in Protestant areas. Using county‐ and town‐level data from the first Prussian census of 1816, we show that a larger share of Protestants decreased the gender gap in basic education. This result holds when using only the exogenous variation in Protestantism due to a county's or town's distance to Wittenberg, the birthplace of the Reformation. Similar results are found for the gender gap in literacy among the adult population in 1871.  相似文献

Superior corporate reputations can have strategic value for firms. Of the “multiple reputations” associated with each firm, we focus on the perceptions of the general public. The public represents the most widely defined stakeholder group but has attracted the least amount of research interest to date. Drawing on data for German firms, this study demonstrates that superior reputation perceptions issued by the general public increase shareholder value, as measured by future stock returns. This study provides a more nuanced understanding for this novel finding. Applying a conceptualization of reputation that balances both its affective and cognitive components, we find that reputation perceptions that are driven by nonfinancial aspects are more value relevant in the future than reputation perceptions that are driven by previous financial performance.

Globalization has substantially transformed the fashion industry. Firms that conduct innovative marketing campaigns for SPA brands, also known as fast fashion, are operating worldwide. Because SPA brands tend to have short trend cycles, corporate profitability is sensitive to consumers' attitudinal changes. The authors of this study establish a theoretical framework by examining research trends related to customer equity at home and abroad by delving into the current state of global SPA brands, defining customer equity, developing customer equity measurements, and conducting empirical analyses. This study uses structural equation models to analyze corporate marketing activity effects on customer lifetime value through brand attitude. Although earlier studies identify customer equity as driving value equity, brand equity, and relationship equity, the authors introduce social network equity as another driver.  相似文献

To date, little is known about how working time preferences and fair wage perceptions affect employees’ entrepreneurial intentions. Using data from the German Socio-Economic Panel Study, we provide first evidence that the difference between the actual and desired amount of working hours in paid employment is positively related to the propensity to switch to self-employment. Furthermore, our analysis supports the hypothesis that employees who perceive their current wage level as very unfair are more likely to have higher entrepreneurial intentions. However, the closer actual wages get to the wage levels perceived as fair, the more employees are likely to remain in their current employment situation. We also tested the interaction effect of working time preferences and fair wage perceptions. In line with our theoretical considerations, we find that employees who perceive their wages as unfair and, simultaneously, prefer different work hours have the strongest entrepreneurial intentions.  相似文献
