Food security and hedonic behaviour: a case study of Sao Tome e Principe
1998
Carvalho, B.R.P de
Food security is still one of the main concerns in economic policy making in less developed countries. The objective of the present study is to analyse technological innovation and technological change induced by economics forces, with special attention to consumer behaviour. Consumer choice is studied together with the technological change process from the consumption side, such that efficiency problems can be handled if a certain number of weak assumptions can be accepted. The framework of the Lancaster model is used to study the impact on food security on Sao Tome' e Principe, changing from a centralised economic policy to a market oriented economy. The paper addresses the need to understand how consumption innovation with the introduction of locally produced food consumption can be an efficient solution from the consumption point of view. The results obtained with the introduction of matabala into the consumption choice set show that free market functioning supports local products consumption as an efficient solution in Sao Tome e Principe.
