| The estimation of large demand systems to investigate the patterns of consumption of households is notoriously difficult. This study develops a modified Almost Ideal Demand System model based on a flexible two-stage budgeting demand modelling framework to examine the effect of estimation procedures (Bottom-up and Top-down) on South African household food consumption parameters. Household food consumption was divided into seven broad food groups: meat and fish; grains; dairy products; fruits; vegetables; other foods. The demand systems were estimated using data from the 1993 South Africa Integrated Household Survey (SIHS) conducted by the South African Labour and Development Research Unit (SALDRU). Empirical results indicate that the Top-down approach is... |

| During the past decade the Indian chickpea industry underwent a dramatic structural shift following the implementation of market-oriented policies by the Government of India. This paper examines consumer attitudes to quality characteristics of chickpea in India. A linear hedonic price model is estimated using auction price and quality data of chickpea samples obtained from major markets in India. Empirical results indicate that specific physical quality characteristics and purity standards are important factors influencing the price of chickpea in India. Thus, there may be an incentive for domestic producers and sellers of chickpea and exporting countries to improve the quality of their product, if improvements in specific physical characteristics... |

| An Almost Ideal Demand System model is used to examine consumer behaviour in India using household survey data for the period 1973-74 through to 1993-94. The empirical results indicate that, for commodity groups, demand is inelastic, except for other foods and non-foods. The expenditure elasticity estimates indicate that milk and non-foods are luxury goods, while pulses, cereals, edible oil, meats, fruits and vegetables and other foods are necessities in the Indian diet. The results indicate that, for any increase in future expenditure, the largest percentage increase will be allocated to non-foods, followed by cereal, other foods, milk, fruits and vegetables, edible oil, pulses and meats, in that order. Estimates of future food supply and demand growth in... |

| Optimal intertemporal investment behaviour ofAustralian pastoralists is modelled using panel data for the period 1979–1993.Results indicate that quasi-fixity of inputs of labour, capital, sheep numbers and cattle numbers is characteristic of production in the pastoral region. It takes about two years for labour, four years for capital and a little over two years for both sheep numbers and cattle numbers to adjust towards long-run optimal levels. Results also indicate that, after accounting for adjustment costs, own-price product supply and input demand responses are inelastic in both the short and long run. |

| India is the largest producer and importer of pulses in the world. Since 1970, the Indian food economy has undergone major policy reforms, including trade liberalisation, that had the effect of opening up its domestic pulse market to international trade. This market is very lucrative and of major significance to the world pulse economy. Therefore, given the increasing evidence linking import demand and economic variables, an understanding of the impact of these variables on import demand for pulses in India is warranted. The import demand functions for total pulses, chickpea and lentils were estimated by autocorrelation regression procedure using time-series data for the period 1970 through to 2000. Empirical results indicate that real GDP, population,... |

| South Africa is emerging as a major player in the world agricultural products market. This study investigates aggregate food demand patterns in South Africa using a linear approximate almost ideal demand system (LA/AIDS) modeling framework. Data from a 1993 integrated national household survey are employed in the analysis. Empirical results show that demand for meat and fish, grains, dairy products, fruits, vegetables, and other foods are generally price elastic. The expenditure elasticities imply that meat and fish and grains are luxury products, whereas dairy products, fruits, vegetables and other foods are necessities in the household diet. The results also indicate that if income of households increases food expenditure on meat and fish and grains... |

| South Africa has one of the highest cases of HIV infections in the world. With the epidemic continuing at an alarming rate, the government of South Africa has regarded the HIV/AIDS epidemic a developmental and socio-economic policy issue. The study explores the impact of HIV/AIDS on food demand in South Africa. The food demand function is specified and estimated using time-series data for the period 1970 to 2000. Simulation analysis is performed to examine the impact of ‘with AIDS’ and ‘without AIDS’ scenarios. The empirical results indicate that the HIV/AIDS epidemic could have a major impact on food demand patterns for selected food items in South Africa. |

| The Indian Sub-Continent (ISC) is the largest pulse producing and consuming region in the world. Australian scientists, producers, processors and exporters require detailed information about these markets. One study of these markets aims to describe the Indian chickpea market and to quantify the value of quality traits in the market using statistical analysis. This paper describes the Indian chickpea market and reports the results of about forty interviews with wholesalers, retailers, processors, brokers and commission agents which were conducted in eight key Indian markets in May and August 1999. A subsequent paper will present the results of an econometric analysis, which attaches values to the product traits of samples taken at the time of the... |
