The negative consequences of school bullying on academic performance and mitigation through female teacher participation: evidence from Ghana

Exploiting data from Ghanaian schools’ eighth grade students collected in 2011, we estimate the causal effects of school bullying on academic achievement and gender-based mitigating approaches by using propensity score matching (PSM) and doubly robust (DR) estimator approach. We find that students victimized by bullying score at least 0.22 standard deviation lower than their peers in a standardized mathematics examination. Meanwhile, we document that the effect of bullying is significantly attenuated in the presence of female teachers in the classroom. These results hold through a set of robustness checks including placebo regressions and matching quality test. We explain the results through gender difference in teaching paradigm and conclude that a feminine management approach in class is required to reduce the effect of bullying.     

The Stock Market and the Financing of Corporate Growth in Africa: The Case of Ghana

This paper examines corporate financing patterns in Ghana, in particular, whether listed Ghanaian corporations make considerable use of the stock market to finance their growth. The paper also examines econometrically the effect of stock market development on the importance of debt relative to external equity in the balance sheet of Ghanaian firms. The results show that the average listed Ghanaian firm finances its growth mainly from short-term debt. The stock market, however, is the most important source of longterm external finance. Stock market development tends to shift the financial structure of Ghanaian firms toward more equity and less debt. Overall, the evidence suggests that the stock market is a surprisingly important source of finance for funding corporate growth.     

Managerial social capital,strategic orientation,and organizational performance in an emerging economy

This study replicates and extends previous research focusing on China, to a sub‐Saharan African emerging economy environment. Specifically, the study directly replicates the impact of social capital derived from the micro‐managerial networking relationships and ties with top managers at other firms and government officials on macro‐organizational performance using data from Ghana. This study further extends previous work by examining the impact of social capital derived from managerial social networking relationships and ties with community leaders on organizational performance. It examines how the relationship between social capital and organizational performance is contingent on an organization's competitive strategic orientation. The findings suggest that social capital developed from managerial networking and social relationships with top managers at other firms, government officials (political leaders and bureaucratic officials), and community leadership enhance organizational performance. The findings from the contingency analyses reveal some interesting trends. The impact of social capital on organizational performance differs between firms that pursue the different competitive strategies (low‐cost, differentiation, and combination of low‐cost and differentiation) and those who do not pursue those strategies.

Does human capital constrain the impact of foreign direct investment and remittances on economic growth in Ghana?

This article empirically investigates whether human capital constrains the impact of Foreign Direct Investment (FDI) and remittances on economic growth in Ghana. An economic growth model for Ghana is specified and estimated using Fully Modified Ordinary Least Squares (FMOLS) estimator and employing annual data spanning the period 1965 to 2008. Empirical results indicate that FDI and remittances are key determinants of economic growth in Ghana. Results indicate that human capital enhances the impact of FDI and remittances on economic growth. Although both government expenditure and trade openness are growth-enhancing, government expenditure appears to crowd-out private investment. Empirical results also indicate that domestic inflationary pressures, unstable political environment and volatile global economy exert a negative impact on economic growth in Ghana.     

The Real Estate Frontier

Africa's major cities are experiencing dramatic transformation as a result of growing real estate investment. This article explores whether existing theories can explain the dynamics of urban redevelopment in an African context, and how African cases can inform new theorizations of real estate driven urban transformation. Examining the utility of theories of gentrification and speculative urbanism for understanding urban redevelopment in Accra, Ghana, it argues that urban redevelopment in this city has been shaped by its particular (post)colonial history of state land acquisition and urban planning. Rather than simply identifying empirical variation on established theories, however, the article draws on recent research on commodity frontiers to propose an original theorization of urban redevelopment in Accra in terms of the production of a ‘real estate frontier’. This real estate frontier is characterized by the incremental and contested commodification of state land to enable the growth of the real estate sector in the city. The article concludes by calling for a comparative research agenda to better understand real estate frontiers globally.     

A socio‐economic assessment of cowpea diversity on the Ghanaian market: implications for breeding

Given the importance of cowpea [Vignaunguiculata(L)Walp] in fighting malnutrition and poverty, a socio‐economic assessment of cowpea diversity found on the Ghanaian market was conducted. The objective was to investigate emerging consumer preference for cowpea and make recommendations for the development of tailor‐made varieties. Forty‐seven cowpea accessions were collected from traders interviewed for morphological characterization to ascertain the degree of diversity. Data was subjected to Hierarchical Cluster Analysis using Genstat Discovery Edition 3 software and variations among the cowpea varieties based on the selected seed traits established. Cowpea varieties found on the markets were broadly categorized into foreign and local varieties and usually named after their sources. Foreign Cowpea varieties were very popular on the markets surveyed as reflected in the per cent distribution of respondents by cowpea varieties sold; Niger (52%), Burkina Faso (50%), Togo (46%), Lagos (36%) and Ghana (18–21%). At the trader level, the order of preference for cowpea characteristics was cleanliness (stone free and no dirt), colour (white seed colour), easy to cook, taste, size, less weevil damage, dryness and place of origin ranked in decreasing order of importance. At the consumer level, cleanliness that was also tied to the extent of weevil damage was ranked most important. This was followed by seed colour (preferable white), short cooking time, size and taste. From the sociological perspective, concerns are raised on the impact of past cowpea breeding activities giving the level of competitiveness and market performance of locally improved varieties observed. Recommendation is made for traders and consumers to be considered as relevant actors in all the stages of crop improvement and breeding activities. This is crucial for enhanced small‐holder farmer market access and strengthened food networks in rural economies.     

Climate Change,Crop Selection and Agricultural Revenue in Ghana: A Structural Ricardian Analysis

We apply a Structural Ricardian Model (SRM) to farm‐level data from Ghana for seven principal food crops in order to model the factors which influence farmers' decisions about which food crops to grow and the revenue conditional on these choices. Our application of the SRM incorporates a flexible functional form to allow for the possibility that the effects of temperature and rainfall may not be linearly separable. We use this model as a basis for simulations of the effects of climate change. These simulations suggest that extreme climate change will lead to a significant reduction in the average net revenue per hectare from maize, which accounts for over half of current food production. Across a range of climate change scenarios, there is also substantial substitution of maize for heat‐tolerant millet, and a reduction in the cultivation of other crops. Under most of the climate change scenarios that we consider, these results imply a substantial reduction in the aggregate value of agricultural production, since millet is the lowest‐value crop.
