| An exploratory market study of cowpea products in Ghana using data from case studies of consumers, personal interviews of processors and market surveillance of retail outlets indicated that the cowpea processing industry has low milling capacity, low production level, and few small operators most of whom have been in the business for less than six years. Cowpea flour, the main value added product, is typically sold in bulk or unbranded small packages through retail and wholesale outlets and directly to consumers including individuals, institutions and the catering industry. Although a high proportion of processors are aware of the new cowpea utilization technologies, only a low percentage have capacity expansion plans within the next two years. A large... |

| The forecast performances of the fixed coefficient demand model are compared with those of spline function and the Cooley-Prescott varying parameter demand models using consumption and price data for beef, pork, chicken and turkey. In general, the varying parameter models outperformed the fixed coefficient model and the spline function varying parameter model appears to be slightly superior to the Cooley-Prescott model. However, no single model was consistently superior over all the commodities in the capacity to predict either the turning points or commodity levels. Apparently, the explicit specification of structural change using spline rather than random coefficient model offers some improvement in commodity forecasting. |
