RESUMO

The main objective of this thesis was to test the hypothesis that the woman’s opportunity costs of time affects positively the consumption of foods that are easy and quick to prepare and negatively the consumption of foods that are time intensive. This study uses micro data from the “Pesquisa de Orçamentos Familiares” - Family Budget Research (POF) 2002- 2003, carried out by the “Instituto Brasileiro de Geografia e Estatística” – IBGE – the Brazilian Institute of Geography and Statistics. Based on the theory of Household Production and making use of an econometric model – Heckman two stages procedure, it was aimed to evaluate the influence of the woman’s opportunity costs of time and other factors such as the level of household income, the family formation, urbanization, among others, on the household consumption of a distinct group of foods – bean, rice, potato, cassava, meat, wheat flour, readymade foods, bread, yogurt, soft drinks and juices - and on the consumption of foods eaten outside the home. The main results show that there has been a significant change in the standards of eating habits of the Brazilian families since the 1970’s. As an example, it was cited the reduction of 46% in household rice consumption and 37% in the bean consumption and, an increase of 490% in the soft drinks consumption and 216% in the ready-made foods. The main socioeconomic indicators show intensification in the urbanization process in Brazil, that is, currently 83% of the Brazilian population lives in urban areas, while in 1970 this percentage was only 56%. Besides that, 54% of the Brazilian women that are the head of the family or spouse are working and 26% of the heads of families in Brazil nowadays are women. As for the factors that affect the standards of consumption, it was verified that the woman’s opportunity cost of time is directly related to an increase in the probability of consumption and of the household expenses on foods that demand a shorter time to be prepared, for example, the ready-made foods, bread, soft drinks and juices, yogurt and foods eaten outside the home and, to a reduction, in the probability of consumption as well as in the household expenses, on “traditional foods” such as bean, rice, cassava, meat and wheat flour that, in general, demand a longer time to prepare. All the variables, woman’s opportunity costs of time, income level, urbanization and family formation were highly significant and important to determine the standards of food consumption in Brazil.
