ABSTRACTThe study examines the differential effects of capital flows on economic growth in Ghana over the period 1970–2014 using autoregressive distributed lag (ARDL). Breakpoint unit root tests are employed to cater for structural change and breaks in time series. Afterwards, these break dates are fed into the ADRL model as dummy variables to allow for the computation of a more robust cointegrating vector. The findings indicate that in both the short and long run capital flows (i.e. FDI, aid, and external debt) have negative effects on economic growth. However, remittances exhibit positive insignificant elasticity in all the regressions. Further, the empirical results show that while the impact of trade, gross capital formation and population growth on growth are mixed, that of inflation is negative. The results of the study are consistent with the idea that the impact of capital flows in Africa has been exaggerated. 相似文献

Demonstrating compliance with food safety requirements of the global food economy is a prerequisite for access. This article presents an overview of the governance within global value chains and their impact on the prospects of developing countries accessing and participating in the global food manufacturing value chain. Based on fieldwork undertaken in Ghana, the article investigates the issues that hinder compliance of the Ghanaian food manufacturing sector with the basic requirements of food safety and investigates the potential role of a technical regulation in enhancing compliance, and therefore participation, in the global food manufacturing economy. 相似文献

This paper examines the cross-sectional variability in the market valuation of R&D expenditures in the pre-packaged computer software industry. Consistent with some prior research, this paper argues that R&D spending is valued heterogeneously by the stock market, and derives hypotheses regarding the determinants of the cross-sectional heterogeneity in the market valuation of R&D. The empirical tests use an extensive database containing product level information of software firms between 1994 and 1998, along with accounting and stock price data of the same period. The test results, consistent with our hypotheses, show that R&D spending is more valuable for firms with larger market shares, higher percentage of technical employees, and those that have diversified into different product categories. The results also indicate that market valuation of R&D spending is a function of product life cycle. 相似文献

This study examines whether analysts’ forecasts exhibited increased herding behavior following the adoption of Regulation Fair Disclosure. A recent model by Arya et al. [Arya, A., Glover, J., Mittendorf, B., Narayanamoorthy, G., 2005. Unintended consequences of regulating disclosures: The case of Regulation Fair Disclosure. Journal of Accounting and Public Policy 24 (3), 243–252], using a discrete-time information cascade-based model, projects that one potential consequence of Regulation Fair Disclosure might be increased herding by financial analysts, although previous studies examining the economic consequences of Regulation FD have generally not found any averse consequence for investors. We examine financial analysts forecasting behavior before and after the adoption of Regulation FD in order to determine if such herding of forecasts occurred empirically. Our general finding is that increased herding behavior cannot be detected among either the firms most directly impacted by Regulation FD (those which used to hold closed press conferences), or those least affected (i.e., firms that used to either hold open or no press conferences). However, because analysts face diverse incentives for engaging in either herding or anti-herding behavior, our results are not interpretable as an empirical test of the Arya et al. (2005) theoretical model. 相似文献

The purpose of this study was to investigate whether knowledge about government entrepreneurial support and entrepreneurial support institutions and their services have an influence on entrepreneurial intention and its antecedents. The study was carried out by means of a cross-sectional survey using a structured questionnaire. The sample consisted of 355 final-year commerce students from two universities located in two of South Africa’s most rural provinces, namely the Eastern Cape and Limpopo. The Statistical Package for the Social Sciences was used to analyse the data. The results indicate that the respondents could hardly access information about entrepreneurial support offered by the government and support services available, and had a very low level of knowledge about these support services. The findings revealed some significant relationships between the knowledge of entrepreneurial support and entrepreneurial intention, perceived behavioural control, subjective norms and entrepreneurial self-efficacy. 相似文献

Private Sector Participation in the Provision of Quality Drinking Water in Urban Areas of Ghana: What Do Households Want and Can Afford? 下载免费PDF全文

This study conducts a survey among households in three cities in Ghana on how water delivery should be managed. The contingent valuation method was used to estimate the willingness to pay for improved water delivery under private sector participation. Results indicate that most households will remain connected to their current water supplies if private sector is engaged to improve water delivery at higher monthly water bills. Given that the mean household monthly water bill of GH¢10.82, the results indicate that there is demand for water quality improvement, and private sector engagement is likely to provide these services. However, this policy measure marginalises the poor in terms of access to water. Therefore, private sector participation in water delivery may require a complementary programme to promote access to water. 相似文献

Although Australia has had State and Federal antitrust laws for most of the twentieth century, its antitrust jurisprudence has only developed significantly since the enactment of theTrade PracticesAct 1974. Judges have had to come to grips with economic concepts not readily amenable to syllogistic reasoning and traditional fact finding processes. There has been increasing sophistication in judicial reasoning in the area of competition law. However restrictions placed by the rules of evidence upon the role of expert economists have attracted criticism. A new rule of court enables such testimony to be received by way of argument or submission rather than as evidence. This reflects the evaluative and normative nature of many of the judgments required under competition laws. It also provides an opportunity for a more fruitful and constructive interaction between economists and the judiciary in the application of such laws. 相似文献
