Fertilizer use in Nigeria is estimated at 13 kg/ha, which is far below the 200 kg/ha recommended by the Food and Agricultural Organization (FAO). The objective of this investigation was to identify the determinant factors of farmers’ participation in Nigeria's Growth Enhancement Support Scheme (GESS). In addition, we determined the impact of the GESS on fertilizer use in rural areas. A total of 1,200 rural farmers were sampled across the six geopolitical zones of Nigeria. Results from the use of a recursive bivariate probit model indicated that GESS significantly impacted on the access and usage of fertilizer among the rural farmers; and that contact with extension agents, ownership of mobile phones, power for charging phone batteries, value output, mobile network coverage, ability to read and write were positive determinants of rural farmers’ participation in the GESS; whereas increased distance to registration and collection centers, and cultural constraints to married women reduced farmers’ tendency to participate in the GESS. The findings suggest that farmers’ participation in the GESS is a critical factor for raising fertilizer use in Nigeria. This implies that food security in sub‐Saharan Africa can be achieved by increasing the participation of rural farmers in the GESS. 相似文献

ABSTRACTWe assess the impact of a new corporate social responsibility (CSR) model of multinational oil companies on the development of rural young people (RYP) in cultural tourism in the Niger Delta of Nigeria. Six hundred RYP were sampled across the rural Niger Delta region. Using the logit model, results indicate that RYP have remained widely excluded from the General Memorandum of Understandings (GMoUs) interventions in cultural tourism projects due to the traditional beliefs that cultural affairs are prerogatives of elders, a caveat to the youths. This implies that if the traditions of the communities continue to hinder direct participation of the RYP from the GMoUs cultural tourism project interventions, achieving equality and cultural change would be limited in the region. The findings suggest that since handicrafts are key cultural products consumed in the tourism industry, GMoUs can play a role in helping to create an appropriate intervention structure that will be targeted towards youth empowerment in the area of traditional handicraft. This can be achieved if the Cluster Development Boards would focus on integrating rural young artisans into local tourism value chains, ensuring they benefit economically from the sector, and creating space for the views of RYP indigenous handicrafts knowledge. 相似文献

This study investigates the impact of the abolition of mandatory retirement on earnings profiles of faculty in postsecondary
institutions. The Age Discrimination in Employment Act (ADEA) excluded faculty from the protection of age discrimination laws
until January 1, 1994, due to perceived adverse effects of this legislation on the academic labor market. After 1994, research
has found that more faculty are remaining employed beyond the age of 70 and more institutions are offering early retirement
plans. This study adds to the literature by finding that the policy change has steepened age-earnings profiles for cohorts
entering the labor market, suggesting a stronger job attachment, and, potentially, efficiency gains. 相似文献

We test a job ladders theory of career progression within internal labor markets as developed by Lazear and Rosen (1990). The theory argues that gender promotion gaps are due to sorting of men and women into career tracks with different promotion opportunities based on ex ante quit probabilities. Analyzing US federal government employees using a dynamic unobserved panel data model, we find that job assignment is one of the strongest predictors of gender differences in promotion. We also find that women have to jump higher performance hurdles to promote across grades, but, within grades, their promotion probabilities are comparable to those of men. In this organization, women can be found in both fast- and slow-track jobs, based on their promotion history, suggesting that unobserved heterogeneity is revealed to the firm over the worker's career. 相似文献

The Junior Reserve Officers' Training Corps (JROTC) is a high school initiative that serves many at‐risk students. Its goals range from reducing dropout rates and improving academic achievement to preparing students for military careers. Using data from High School and Beyond (HSB) and the National Educational Longitudinal Study (NELS), we estimate average treatment effects on students attending schools that typically host JROTC. Applying a two‐stage matching technique, we find that JROTC participants have poorer academic outcomes than other students; although, a large portion of these differences is explained by their at‐risk status. In addition, program effects appear to differ by demographic group, with black participants having lower dropout rates than white participants. The program also appears to improve self‐esteem scores of females. Although the majority of JROTC participants do not join the military, we find large marginal enlistment effects. 相似文献

This study provides a comprehensive analysis of the distributional effects of distance learning (DL) on academic success, as measured by course grades and completion. Using data of over 1.2 million courses taken by about 200,000 U.S. Navy sailor-students at more than 1800 U.S. institutions during 1994–2007, we find that distance delivery of education is associated with poorer outcomes. At the mean, DL delivery is associated with 0.19 lower course grade points; however, the mean effect masks the more pronounced negative effects of DL in the bottom two-thirds of the distribution—where DL lowers grades by as much as 0.8 points. Using variation only among marginal students—those who tend to fail some of the courses that they take, our estimates indicate traditional face-to-face delivery is associated with 2.4 times greater likelihood of successful course completion than if it was delivered distant. These findings suggest that targeting DL courses to certain students may be more cost-effective. 相似文献

This paper uses country-level data of European Economic Area countries between 1989 and 2016 to examine the interactions between economic growth, innovation, and financial market activities, with specific reference to the bond and insurance markets. Our intent is to know whether causality runs among these variables both ways, or not at all. Using a vector error correction model, the study finds that financial market activities and economic growth determine innovation activities in these countries. Additionally, the study also finds bidirectional Granger causality between financial market activities and economic growth, as well as between innovation activities and economic growth. 相似文献
