Undue taxing of the agriculture sector could constitute a disincentive to agricultural production in most low-income African countries where agriculture is being taxed for industrial development. There is an argument that the high level of taxation of agriculture in favour of industrialization is in part due to the underestimation of the supply response of the agricultural sector. This study tests the theoretical hypotheses that only price, non-price and natural disincentives respectively pose problems for agricultural growth. Johansens approach to co-integration analysis was employed to test these hypotheses using the time-series data from the Central Bank of Nigeria (CBN) statistical database. The long-run price elasticity of supply is 0.13 and... |

In examining demand for a product it is useful to think of consumers not as purchasing the product, but as purchasing its characteristics that provide utility. Consequently, it is important to measure the specific characteristics that consumers perceive as providing them with utility. In this article a hedonic pricing model is used to investigate the influence of different cowpea characteristics on cowpea prices in Senegal. The results provide valuable information for research institutions, producers, and traders. Cowpea plant breeders should emphasise large grain size as the main characteristic since buyers are willing to pay a premium for this characteristic. This should translate into higher returns on R&D. There exist differences between markets in... |

The liberalization of the agricultural sector and phasing out of past protection mechanisms in South Africa saw the introduction of a process of tariff reform. Furthermore, a system of tariff rate quotas was introduced in compliance with WTO regulations. This study uses a partial equilibrium comparative static model to measure the welfare effects of further liberalization in the livestock industry of South Africa, particularly in meat products using four policy scenarios. The traditional method of welfare analyses using the CS and PS was applied, while the EV was used to integrate a well-behaved objective function. Although the CS and PS could have over-estimated welfare due to the fact that the demand system used in this study is non-linear, they still... |

This study investigated asymmetric price and volatility spillover in the broiler value chain. The data used for the study includes farm and retail broiler monthly prices dated from January 2000 to August 2008. The threshold autoregressive (TAR) and momentum threshold autoregressive (M-TAR) models were used to investigate asymmetry in farm-retail market prices, whereas the exponential generalised autoregressive conditional heteroskedasticity (EGARCH) model was used to measure price volatility and the volatility spillover effect between retail and farm prices. Price asymmetry was found between farm and retail prices with retail prices responding more rapidly (with a lag) to negative than positive changes in farm price. The results indicate that within one... |

This paper evaluates the comparative economic advantage (CEA) of irrigated long-term crops (cherries, peaches, apples and asparagus) in the four agro-ecological zones of Lesotho based on analyses of profitability coefficients and domestic resource costs. The analysis was carried out using the net present value (NPV) approach. The CEA analysis yielded higher private returns relative to economic returns in the lowlands, Foothills, the Senqu River Valley and the Mountains of Lesotho for all the crops examined. In the lowlands zone all products have a RCR of lower than one indicating a comparative advantage. In the Foothills only apples and peaches were investigated, and both show a comparative advantage of equal strength. In the Senqu River Valley the result... |

The Effective Protection Ratio (EPR) is used in this study as a measure of the impact of policy distortions on agricultural producers. The results of the EPR analysis show that in 1995, most of the interventions supporting agricultural production have disappeared, particularly if the production is aimed at the domestic market. This holds for basic grains and oilseeds, as well as other products such as potatoes, cotton and tobacco, across all regions. Beef cattle and sheep production is also not being favoured by support in any of the regions. On the contrary, a number of commodities are effectively being taxed. |

This paper analyses meat consumption trends in South Africa. Despite the fact that aggregate per capita meat consumption remained relatively constant during the last 34 years, significant changes were observed in the per capita consumption among different meat categories. By applying Ordinary Least Squares (OLS) and the Johansen co integration approach to a conventional demand function, significant changes in the contributions of economic and non-economic factors towards meat demand were identified over time. From the analysis it is apparent that non-economic factors play a greater role in determining meat consumption in South Africa. |

According to the RCA and RCA# the beef sub-sector in South Africa has shown a revealed comparative disadvantage for 17 out of the 22 years to 2002, while the maize sub-sector showed a revealed comparative advantage for 18 out of the same 22 years. However, this article argues that these results do not show the real state of competitiveness that exists in these sub-sectors, mainly because RCA measures should not be used to make definitive conclusions whether an industry, sector or sub-sector is competitive, nor whether it uses scare resources efficiently. RCA measures explain in more accurate ways, relative to a simple analysis of export trends, how a country features in the context of world trade. Hence, one possible application of RCA measures is to... |

In an effort to gain a better understanding of the trade in fish products by South Africa a starting point is examining South Africa's current trade in fish products. Useful tools in this regard, the Gini-coefficient, used to examine the degree of concentration for fish exports, and the intra-industrial trade coefficient (IIT), and used to examine the balance of international fish trade by South Africa. The Gini-coefficient for fish exports shows that fish export by South Africa is highly concentrated. The trend in concentration appears to have remained constant, and therefore the South African fisheries industry may boast a competitive advantage. However, cognisance should be taken of the fact that such a high level of concentration may render the South... |

One of the most important policy measures used by government to influence agricultural production and trade patterns are tariffs. A substantial depreciation in the exchange rate will not be enough to compensate for the negative effects of removing tariffs if the playing field is not level for producers in South Africa. Although the import multiplier show that less inputs will be imported, this saving on foreign exchange is not big enough to outweigh the total impact of imports on the balance of trade. The value-added multiplier clearly indicate that reinvestment and consumer spending (buying power) in agriculture will receive a severe blow. Employment will be reduced, thus increasing the supply of labour into other sectors. |

The focus of this research was to investigate the comparative advantage of the potato industry in seven potato production regions in South Africa. Potatoes are the most important vegetable crop produced in South Africa. In 2008 it contributed more than 40% to the total production of vegetables in South Africa and it accounted for more than 20% of the value of all fresh produce sold on all the major national fresh produce markets. This study uses the Resource Cost Ratio (RCR) methodology that provides an explicit indication of the efficiency with which production alternatives uses domestic resources to generate or save foreign exchange. The Nominal Protection Ratio (NPR) and Effective Protection Coefficient (EPC) were also calculated. The results show that... |

The pace of rural-urban migration relative to urban job creation is of particular relevance in relation to the level of urban unemployment and poverty in many developing countries. Faced with high levels of urban unemployment and other socio-economic problems governments in developing countries adopted several policies to ameliorate the situation. Since such policies were mainly urban biased in nature it not only failed in most cases but also in some instance exacerbated the situation by stimulating more rural-urban migration. Rural-urban migration occurs where there is economic disparity between rural and urban areas. Some economists therefore, argue that boosting agricultural productivity and/ or income can reduce the incidence of economic problems... |

There is increasing evidence that most of the fear expressed by consumers in terms of the link between cholesterol in the diet and heart disease is, amongst others, related to the amount of fat in red meat and dairy produce. The result is that many consumers are cutting back on, if not avoiding, red meat products. A major challenge ahead of the beef industry is to supply a product that complies with the demands of more sophisticated and health conscious consumers. But, even if the beef industry could respond positively to consumers needs, it is uncertain whether consumers would pay more for beef containing less fat. In this paper the willingness of consumers to pay for less fat in selected beef cuts (T-bone and rump) was investigated with a... |

Relative change in agricultural prices determines farmers` investment decisions, productivity and income. Thus, understanding the factors that influence agricultural prices is fundamental for sustainable growth in this sector and the rest of the economy. This paper investigates the short- and long-run impacts of monetary policy changes on relative agricultural prices in South Africa by employing Johansen cointegration analysis and the Vector Error Correction Model (VECM) respectively. The results of Johansen cointegration analysis reject the long-run money neutrality hypothesis which suggests that the rate of increase in prices is not unit proportional to the rate of increase in money supply. On the other hand, the results of the dynamic relationships... |

The main objective of this study is to investigate the determinants of households' pork consumption using a logistic regression procedure. The model was initially fitted with ten variables, selected from factors identified by precious studies, that affect meat consumption in South Africa. Six of these variables were found to be significant at the 10 per cent significance level and all had the expected signs. These include household monthly income, current household monthly expenditure on meat, relative price of pork, preference for value-added pork products, prices of substitutes (the most preferred household meat type), and response of household to change in pork quality. The result obtained was further analyzed to compute partial effects and to conduct... |

The conditional volatility in the daily spot prices of the crops traded on the South African Futures Exchange (yellow maize, white maize, wheat, sunflower seed and soybeans) is determined. The volatility in the prices of white maize, yellow maize and sunflower seed have been found to vary over time, suggesting the use of the GARCH approach in these cases. Using the GARCH approach, the conditional standard deviation is the measure of volatility, and distinguishes between the predictable and unpredictable elements in the price process. This leaves only the stochastic component and is hence a more accurate measure of the actual risk associated with the price of the crop. The volatility in the prices of wheat and soybeans was found to be constant over... |
