Research background: The article has address the issue of sustainable consumption which is becoming increasingly important on account of the adverse social and environmental consequences caused by the development and growth of societies. Sustainable consumption encourages to make rational...

The prudence theory predicts that economic insecurity reduces all consumption expenditures. We question this prediction by estimating the effect of economic insecurity on various expenditure items using an Australian longitudinal data set (HILDA) and panel regressions. Our results confirm that...

This study proposes a methodology for estimating child support, which combines two approaches. The first corresponds to the marginal approach, which approximates the cost of the child maintenance by comparing an equivalent income from households with the same level of well-being. The second is...

Do individuals marry and divorce for economic reasons? Can we measure the economic attractiveness of a person's marriage market? We answer these questions using a structural model of consumer-producer households that is applied to rich data from Malawi. Using revealed preference conditions for a...

Prominent features of differentiated product markets are segmentation and product proliferation blurring the boundaries between segments. I develop a tractable demand model, the Ordered Nested Logit, which allows for asymmetric substitution between segments. I apply the model to the automobile...

This note explains the equivalence between approximate rationalizability and approximate cost-rationalizability within the context of consumer demand. In connection with these results, we interpret Afriat's (1973) critical cost efficiency index (CCEI) as a measure of cost (in)efficiency, in the...

Experiments on revealed preference often use budget sets that are randomly and independently drawn according to some criteria for each participant. However, this means that the budget sets faced by different individuals are not the same. This paper proposes a method to control for these...

We study whether households can distinguish persistent from transitory income shocks, and the implications for consumption-saving behavior. We construct a novel consumption-saving model where the household must infer the persistent component of its income process from actual income realizations...

This paper provides a revealed preference characterisation of quasi-hyperbolic discounting which is designed to be applied to readily-available expenditure surveys. We describe necessary and sufficient conditions for the leading forms of the model and also study the consequences of the...

Using non-parametric weak separability tests that are extended to allow for measurement errors in the data, a broad group of UK monetary assets is found to be weakly separable from consumer goods and leisure over the larger part of the nineties. Financial innovations have made assets with...
