| A Linear Approximated Almost Ideal Demand System (LA/AIDS), estimated in first differences, was used to anticipate the demand relations for meat (beef, chicken, pork and mutton) in South Africa from 1970 2000. Two tests for weak separability, including an F and Likelihood ratio version, failed to reject the null hypothesis of weak separability, confirming that the four meat products are separable, and should be modelled together. According to the Hausman exogeneity test, the expenditure term in the South African meat demand model is exogenous. As a result, a Restricted Seemingly Unrelated Regression (RSUR) was used to estimate the model, whereafter the parameters were used as to calculate compensated, uncompensated and expenditure elasticities. |

| 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. |

| In this study the demand relations for meat in South Africa are estimated and interpreted. Two demand model specifications, namely the Rotterdam and Linearized Almost Ideal Demand System (LA/AIDS), were estimated and tested in order to determine which model provide the best fit for South African meat data. Tests for separability included an F and Likelihood ratio version. Both tests rejected the null hypothesis of weak separability between meat, eggs and milk as protein sources, indicating that the demand model for meat products should be estimated separately from eggs and milk. Consequently, separability tests between the four meat products fail to reject the null hypothesis, confirming that the four meat products should be modelled together.... |

| About 70% of the Namibian population depends on agricultural activities for their livelihood. Moreover, agriculture remains an important sector to Namibia because its national economy is widely dependent on agricultural production. Cattle producers in the Northern Communal Areas (NCAs) have an option to market their cattle via the formal or informal markets. Efforts have been made to encourage producers to market their cattle through the formal market; however, limited improvement has been observed. In this study a number of factors have been analysed to determine its influences on cattle marketing decisions. Factors influencing the marketing decision of whether or not to sell through the formal market are analysed using the Probit model. Factors... |
