Collective consumption decisions taken by the members of a household may prove inefficient. The impact of such inefficient household decisions on market performance is investigated. At one extreme, market efficiency can occur even when household decisions are inefficient, namely when household...

We develop a method for estimation of price reactions using unit value data which exploits the implicit links between quantity and unit value choices. This allows us to combine appealing Engel curve specifications with a model of unit value determination in a way which is consistent with demand...

The paper presents an extended version of the consumer choice problem. Different from the standard model, prices are not fixed but arise from Walrasian interactions of total demand and a stylized supply function for each of the goods. Three different types of evolutionary algorithms are set up...

Many budget surveys present the interesting features that for a wide range of goods they contain quantity information along with expenditure information, and that the geographical location of households is fairly precise. We take advantage of these features to develop a method for estimation of...

Characteristics models have been found to be useful in many areas of economics. However,their empirical implementation tends to rely heavily on functional form assumptions. Inthis paper we develop a revealed preference approach to characteristics models. We derivethe necessary and sufficient...

Behavioral (e.g. consumption) patterns of boundedly rational agents can lead these agents intolearning dynamics that appear to be “wasteful” in terms of well-being or welfare. Within settingsdisplaying preference endogeneity, it is however still unclear how to conceptualize well-being.This...
