| Sumario: | The article presents information on the labour supply, commodity demand and the allocation of time. Predictions of the behavioural responses to income and commodity taxes and subsidies have become of increasing interest in recent years. The first section of the article summarizes the general implications of the integrated economic theory of the demand for commodities and the allocation of time. The paper also set out the conditions under which the labour supply decision and the allocation of income to expenditure on commodities may be separated, as is implicitly assumed in most empirical work on consumer demand. The second section of the article is a discussion of the data used for the empirical work in the third section. The latter includes the estimation of commodity demand and labour supply functions based on explicit direct and indirect utility functions and some approximate tests of the usefulness of the general empirical implications of the theoretical framework, including a test for whether non-market time may be considered separable in utility from commodities.
