| This paper investigates empirically the factors that influence real agricultural wage rates in Ghana, based on 1957 to 1991 data. The Johansen cointegration framework is used to examine long-run relationships among agricultural and urban wage rates, the domestic terms of trade between agriculture and nonagriculture, urban unemployment, capital stock in agriculture and the size of the rural population. An error correction model is then used to investigate short-run dynamic relationships among the variables. The results show that: (1) there is only one stable equilibrium relationship among agricultural wage rates and their determinants in the long-run; (2) a 1 percent change in the domestic terms of trade between agriculture and non-agriculture leads to a... |

| Cross-border trade in food commodities within sub-regional economic blocks in Sub-Sahara Africa (SSA) is believed to be faster, cheaper, more convenient and welfare-enhancing than overseas trade between SSA countries and the USA, EU and the BRIC countries. The difficulty of commodity arbitrage across international borders SSA is however a fundamental constraint to price transmission, market integration and the realisation of the welfare-enhancing role of cross-border trade in Africa. This study examines the impact of border and distance on price transmission between tomato markets in Ghana and Burkina-Faso. The analysis applies a regime-switching vector error correction model to estimate semi-weekly, wholesale prices of tomato in four tomato markets in... |

| This paper provides a nuanced perspective on debates about the potential for Africa’s smallholder agriculture to stimulate growth and alleviate poverty in an increasingly integrated world. In particular, the paper synthesizes both the traditional theoretical literature on agriculture’s role in the development process and discusses more recent literature that remains skeptical about agriculture’s development potential for Africa. In order to examine in greater detail the relevance for Africa of both the “old” and “new” literatures on agriculture, the paper provides a typology of African countries based on their stage of development, agricultural conditions, natural resources, and geographic location… More broadly, the paper demonstrates that conventional... |

| Unavailability of high frequency, weekly or daily data compels most studies of price transmission in developing countries to use low frequency, monthly data for their analyses. Analyzing price dynamics with monthly data may however yield imprecise price adjustment parameters and lead to wrong inferences on price dynamics. This is because agricultural markets in developing countries operate daily or weekly. In this paper, we investigate the relevance of data frequency in price transmission analysis. We use a standard- and a threshold vector error model to estimate and compare price adjustment parameters for a high frequency, semi-weekly, data and a low frequency, monthly data. The results reveal that adjustment parameters estimated from the low frequency... |

| The paper considers the benefit to agricultural producers from commodity price insurance that provides in every year, but in advance of the resolution of production and price uncertainty, a minimum price for a fixed or variable portion of production. Under the assumption that producers do not change their long term production and income diversification pattern, the theoretical framework suggested leads to explicit formulas for the benefit from providing this type of insurance. The theoretical framework is implemented for Ghana, using the GLSS data to specify various classes of cocoa producing households, and monthly price data for both domestic and international prices to formulate appropriate models for ascertaining price risks faced by producers.... |

| The development pattern in Ghana is characterised by a north-south divide in which the north lags far behind the south. Ghana has achieved sustained growth and poverty reduction during the 1990s, but such growth did not benefit the three poor northern regions and the development gap has increased between the south and north. One of the most important reasons is that much of the growth has been generated by export agriculture in which northern Ghana has little contribution if any. This paper sets out to identify avenues for pro-poor growth in Ghana, focussing on agricultural opportunities, particularly in northern Ghana. Using an economywide, multimarket model and based on time series production data between 1991 and 2000 and Ghana Living Standards Survey... |

| Purpose- The issue of export success and the ability to sustain oneself in international horticultural markets have become more critical in the recent global and economic downturn because of its significance to the economy and to actors in the horticultural export chain. The extent of success is even much critical for enterprises. Therefore this study establishes the factors which influence the intensity of export success which measures the extent of export success. Design- Primary data were collected from 52 managers and representatives of horticultural exporting firms through a semi-structured questionnaire. The tobit model was used to estimate the intensity of export success by horticultural enterprises in Ghana. Findings- The result indicates that,... |

| Crop production is the main source of livelihood for households in Northern Ghana. The government is committed to improving crop production and knowledge about the technical efficiency of crop farms is essential in guiding policy decisions. This paper examined the technical efficiency of 189 crop farms in Northern Ghana using data envelopment analysis (DEA) with bootstrapping. We found that bias-corrected average technical efficiency of the sample farms is 77.26%. The estimated scale efficiency is 94.21%. In a second stage regression, we found that hired labour, geographical location of farms, gender and age of head of household significantly affect technical efficiency. Policy implications of the results are discussed. |
