This paper deals with the regularity problem in the Almost Ideal Demand System (AIDS) in terms of the boundedness of the budget shares within the [0,1] interval. The violation of "cointegration accounting" can be seen just as another consequence of irregularity. The discussion of modifications...

In an overlapping generations maximization framework with consumers, whose information on uncertain future income realizations is front loaded, a closed form aggregate consumption function with CRRA preferences is derived. To have a closed form solution we assume that consumers solve their...

This paper deals with technical progress in the energy efficiency of US households' capital stock (appliances and passenger cars) and its potential for energy saving. An increase in the energy efficiency of households can only be achieved via a different capital stock. The link between the...

Models of consumer behavior play a key role in modern empirical Industrial Organization. In this paper, I survey some of the models used in this literature. In particular, I discuss two commonly used demand systems: multi-stage budgeting approaches and discrete choice models. I motivate their...

An empirical model of managers' demand for agency goods is derived and estimated using the Almost Ideal Demand System of Deaton and Muellbauer (AER 1980). As in Jensen and Meckling (JFE 1976), we derive managers' demand for agency goods by maximizing a managerial utility function where managers...

The paper explores utility measures by combining experiments with mathematical derivations in the psychophysics paradigm. The analysis on the ultimatum game experiment reveals evidences for the utility threshold and thus supports Bernoulli's utility logarithmic law. Both experimental results and...

The paper uses micro cross-section data from the GfK consumer panel for econometric demand analysis of private households in Germany. Contrary to most research which considered \average behavior we extend this approach to consumer behavior for di®erent \intensities of consumption. Our...
