Abstract: Prior to the 1980s, Ghana witnessed an alternating cycle of boom and scarcity, culminating in the introduction of structural adjustment policies in the early 1980s. This paper uses data from the Ghana Forestry Services, Ministry of Food and Agriculture, FAO Yearbook of Forestry Products, Ghana Timber Marketing Board, Quarterly Digest of the Ghana Statistical Service, World Debt Tables, Bank of Ghana, IMF, COCOBOD and Ministry of Finance to examine the impact of SAP on deforestation in Ghana. The paper reveals a negative impact of structural adjustment on deforestation in Ghana through both direct and indirect channels. The most important channel of the effect of SAP on deforestation resulted from the conversion of forestland to crop farming, particularly cocoa farming, during the post‐adjustment period. Even though wood extraction exhibited a negative impact on deforestation, the impact seemed relatively weaker than that of agricultural land use. In addition, while in the long run, deforestation tended to be more responsive to logging than agriculture, in the short run the elasticity of deforestation with respect to agriculture tended to be greater than that with respect to logging. Finally, agriculture was relatively more important in causing deforestation. 相似文献

The article empirically examines the effect of energy prices on economic growth within the Economic Community of West African States sub-region by acknowledging that the effect of energy prices on growth is quintessentially indirect and hence can be tracked through some channels. Exploiting the System Generalized Methods of Moments estimation technique for the period spanning 2002–2015, the results indicate that the overall effect of energy prices on economic growth is significantly negative. This effect propagates mainly through government consumption expenditure and investment, albeit its effect through real interest rate is positive. However, its negative effects on government consumption, investment, and exchange rate significantly overwhelm the positive effect from real interest rate. 相似文献

The study examines the differential effects of capital flows on economic growth in five Sub-Saharan African (SSA) countries over the period 1970–2014. Using the autoregressive distributed lag methodology, the findings show that in the long-run capital flows (i.e. foreign direct investment (FDI), aid, external debt, and remittances) have different effects on economic growth. FDI has a significant positive effect in Burkina Faso and negative effects in Gabon and Niger whereas the impact of debt is negative in all countries. Aid, however, promotes growth in Niger and Gabon whiles it deters growth in Ghana. Remittances, on the other hand, have a significant positive effect in Senegal. Finally, gross capital formation is significant in most of the countries and the impact of trade is mixed. These results suggest that the benefits of capital flows in SSA have been overemphasized. 相似文献

I analyze changes in the target efficiency of the federal minimum wage over the past 25 years. Using static simulation methods I find that minimum wage target efficiency is currently close to its 25‐year peak—of the total monetary benefits generated by a 12% increase in the federal minimum wage, 16.8% would flow to workers in poverty. This exceeds the least target efficient year over this period by 4.7 percentage points and is only 0.6 percentage points below the peak. Furthermore, I find a very strong positive relationship between minimum wage target efficiency and the real federal minimum wage. The implication is that, from an efficiency standpoint, a good time to raise the minimum wage is when it is already high. This discovery raises the possibility that the minimum wage increases the employment of low‐skilled poor individuals relative to the employment of low‐skilled non‐poor individuals. Moreover, this discovery may bolster the rationale for an indexed minimum wage whereby it is prevented from falling to less efficient levels. (JEL J21, J31, J38) 相似文献

There have been few efforts made to identify the positioning of exhibition host countries or cities, even though studies on the positioning of convention host destinations have been popular. Thus, the aim of this study was to assess the positioning of exhibition cities as perceived by a sample of exhibitors who participated in exhibitions held in Hong Kong. A total of 304 questionnaires were collected at the PATA Travel Mart 2006, the Hong Kong Jewelry and Watch Fair, Aircraft Interiors Expo ASIA 2006, MIPIM Asia 2006, and Electronic Asia 2006. The results of this study found that there is a strong competition between major exhibition host cities in Asia, including Hong Kong, Beijing, Shanghai, Singapore, Seoul and Tokyo. The respondents showed the highest preference for Hong Kong and Singapore as an exhibition host destination. 相似文献

Geotourism is one among many types of ecotourism or nature tourism. Cave tourism within geotourism has gained popularity in Korea. The study's objectives include cave tourists' characteristics, segmenting them according to motivation factors, and finally identifying who they are. The sample population for this research consisted of tourists who have visited the Hwansun Cave in Samchuk City. Among a total of 547 questionnaires distributed, 537 questionnaires were used for further data analyses. On the basis of cluster analysis using the motivation factors, cluster 1 was named an “escape-seeking group”, cluster 2 was termed a “knowledge- and novelty-seeking group”, cluster 3 was called a “novelty-seeking group” and cluster 4 was termed a “socialization group”. Differences in socio-demographic variables, beliefs about cave tourism resources, preferred cave tourism products, satisfaction with this tour, willingness to participate in another cave tour and belief in the value of cave tourism resources were found among the four clusters. The study's findings were expected to be helpful in understanding who they are. 相似文献

Market cycles play a great role in reinsurance. Cycle transitions are not independent from the claim arrival process: a large claim or a high number of claims may accelerate cycle transitions. To take this into account, a semi-Markovian risk model is proposed and analyzed. A refined Erlangization method is developed to compute the finite-time ruin probability of a reinsurance company. Numerical applications and comparisons to results obtained from simulation methods are given. The impact of dependency between claim amounts and phase changes is studied. 相似文献

The concept of compound mixed Poisson distributions in actuarial science is used to represent such variables as the total amount of claims or losses payable by an insurer. In this paper, comprehensive collections of approximate forms are derived for the compound mixed Poisson distribution. The calculations involve use of several special functions and their properties. We believe that the results will serve as an important reference in actuarial science. 相似文献
