R&D,Human Capital and Export Behavior of Manufacturing and Service Firms in Ghana

ABSTRACT

The paper carries out a detailed analysis of the effects of R&D and human capital as well as their interactions with innovation on export behavior of manufacturing and service firms in Ghana using a dataset of 720 firms that merges the Enterprise, Innovative Capability and the Innovation Follow-up Surveys respectively for Ghana. Using a bivariate probit regression, the results show that R&D and human capital (employees’ education, slack time and formal training) are positive and significantly related to the propensity for firms to export in Ghana. The cross derivatives (differences) for the interaction terms (R&D and innovation, and education and innovation) also showed that these interaction terms have positive effects on the likelihood for firms to export but are significant only for a negligibly small fraction of the sample. Thus, there is no much statistically significant evidence in support of the mediation role of innovation in the relationship between R&D/education and the export behavior.     

Race Portrayals in Ghana,Kenya, and South Africa Television Advertisements

ABSTRACT

The current study examines racial portrayals in television advertisements from Ghana, Kenya, and South Africa. Whites are over-represented relative to their actual demographic presence in all three countries, and both Blacks and Whites are depicted as over-employed. In general, however, depictions are not significantly different for either race, though there is a hint that a stereotyped portrayal of Blacks as athletes and/or entertainer may be going global.     

Welfare impacts of climate-smart agriculture in Ghana: Does row planting and drought-tolerant maize varieties matter?

This study provides new evidence of the impact of climate-smart agriculture (CSA) – row planting and drought-tolerant maize varieties - on farm and welfare outcomes by estimating a multinomial endogenous switching regression model that corrects for selection bias and farmer heterogeneity in CSA choice. Application of our model to panel observations of 438 households in Ghana show that adoption of CSA increases both yield and intensity of maize commercialization but negatively affect own consumption. Specifically, the magnitude of the impact is relatively higher for adopters of row planting relative to adopters of drought-tolerant maize seeds. These results suggest the need for development practitioners to increase awareness and emphasize the importance of row planting as a key component of climate-smart agriculture.     

Creating space for innovation—The case of mobile telephony in MSEs in Ghana

Mobile telephones have become important tools for socio-economic activities. In Africa, their diffusion is phenomenal. This paper adopts the innovation system conceptual framework for analyzing the state of mobile telephony in Ghana, the trends and implications for enhancing benefits. The paper emphasizes the role of the critical actors, and the internal and external environments they operate in. It uses primary and secondary data in analyzing the real and potential innovative use of mobile telephones by the MSEs in Ghana. It also examines the range of applications of mobile telephones in the MSEs, and assesses current public policies and the outcomes of such policies on innovations in MSEs. Finally, it advocates for a more holistic promotion of innovations from the broad perspectives. Efforts to stimulate innovation must be on the demand side of innovation as well as on the supply side.     

Small Business Reliance on Bank Financing in Ghana

Financing has been identified as a dominant constraint to Ghanaian small and medium-sized enterprises (SMEs). This study explores the determinants of bank financing and debt among Ghanaian SMEs. A panel regression model estimates the relation between the determinants and the bank-debt ratio. The results reveal that bank loans account for less than a quarter of SMEs' total debt financing, and show that the age and size of the firm, along with asset tangibility, have significantly positive associations with the bank-debt ratio. Profitability is significantly and negatively related to the bank-debt ratio. These findings have significant implications both at the firm level and for the support of policies aimed at improving SME financing in Ghana.     

Effects of log export ban policy and dynamics of global tropical wood markets on the growth of timber industry in Ghana

The effects of log export ban (LEB) policy and dynamics of global tropical timber markets on the growth of Ghanaian timber industry were studied. The purpose was to follow the trend in the growth of timber industry from 1984 to 2005 using Fisher index and semi-log regression analysis. The study showed that the volume of plywood, veneer, and processed wood exported before the period of 1984–1995 and during the LEB policy (1996–2005) was, respectively, 6% and 46% of the total exports during those periods. On the contrary, the aggregate price index of all products exported before the LEB policy was up by 129% compared to −3.9% for the period during the LEB policy. A further decline in prices of the most products exported during the LEB policy was found by the study. Thus even though an LEB policy could increase volume share of value-added products, it cannot guarantee growth in prices of wood products.     

Total Quality Management in Ghana: Critical Success Factors and Model for Implementation of a Quality Revolution

In this study, the authors aim to identify the critical success factors and challenges of total quality management (TQM) implementation and propose a model for the successful implementation of a quality revolution in Ghana. The approach in this study was to review existing literature followed by case studies of 15 firms. Three employees (quality manager/director and any two “ordinary employees”) were interviewed to identify the critical success factors that would be appropriate for the implementation of a quality revolution in Ghana as well as the main challenges of quality management they face. Findings revealed that top management commitment, empowerment and involvement of employees, resource availability, competition and increased customer awareness, and a well-functioning quality network are the major factors that are critical and essential if any TQM program is to be successful. Three main problems—management resistance, employee resistance, and resource paucity—were identified as principal impediments to TQM programs.     

The Development of a Scale Measuring Consumers' Selection of Retail Banks in Ghana

The current research attempts to investigate the use of the two sources of dealers' soft channel power (i.e., expert power and referent power) as a means of achieving three desirable channel relationship outcomes in Zimbabwe's channel of distribution system. The field study is conducted in Harare and Chitungwiza, and research data are collected from 447 small and medium-size enterprise (SME) manufacturers. Dealers' expert power and referent power are found to be important sources of channel power that positively influence SME manufacturers' trust, relationship commitment, and relationship satisfaction. It is concluded that managers in dealers' firms can improve their channel relationships with SME manfacturers if they acquire or enhance their expert power and referent power.     

Dollarization,Inflation Targeting,and Inflationary Dynamics in Ghana

ABSTRACT

The impact of dollarization on domestic economic performance, and the welfare implications of high inflation in an inflation targeting environment, have remained a matter of much concern for policymakers in recent years. This study investigates the effects of dollarization on inflation and inflation uncertainty in Ghana for the period January 1990 to December 2017. We apply the exponential Generalized Autoregressive Conditional Heteroskedasticity model together with impulse response and Granger causality tests to explore how dollarization affects the behavior of inflation for the pre-inflation targeting period (January 1990 – May 2007) and post-inflation targeting period (June 2007 – December 2017). The results indicate that dollarization has not played a significant role in the volatility of inflation in Ghana. Also, inflation Granger causes dollarization in both the pre- and post-inflation targeting regimes. Finally, there is a bidirectional causal relationship between inflation and inflation uncertainty following the adoption of inflation targeting monetary policy. We conclude that, although inflation targeting has not presented a significant impact on inflation volatility, it has affected the relationship between inflation and inflation uncertainty in Ghana. The dynamics of inflation volatility and asymmetries present crucial implications which are discussed to guide policymaking.
