Homotheticity induces a dramatic statistical bias in the estimates of the intratemporal and intertemporal substitutions. I find potent support in favor of nonhomotheticity in aggregate consumption data, with nondurable goods being necessities and durable goods luxuries. I obtain the...

Presented is an evolutionary model of consumer non-durable markets, which is an extension of a previously published paper on consumer durables. The model suggests that the repurchase process is governed by preferential growth. Applying statistical methods it can be shown that in a competitive...

How a full glass is sketched by a person is used as an identification of a maximizer/satisficer-type personality. There is evidence that students who interpret the “full glass” description as, in fact, a glass that is filled up to the brim as the maximizer-types and those who draw their...

This paper shows that there is a positive and statistically significant correlation between the short-term discount rate over a monetary reward and the short-term discount rate over a primary reward (chocolate). This correlation, however, is absent among subjects who do not like chocolate and...

This paper discusses solutions derived from lottery experiments using two alternative assumptions: that people perceive wealth changes as absolute amounts of money; and that people consider wealth changes as a proportion of some reference value dependant on the context of the problem under...

The paper presents an alternative interpretation of the experimental data published by Kahneman and Tversky in their 1992 study "Advances in Prospect Theory”, which describes the Cumulative version of their Prospect Theory from 1979. It was assumed that, apart from the operations made during...

Some economists believe that neuroeconomists threatens the theory of economics. Glenn Harrison’s paper “Neuroeconomics: A Critical Reconsideration” (2008) provides some support for this view, though some of the points he makes are somewhat disguised. The field of neuroeconomics is barely...

Substantial evidence has been accumulated in recent empirical works on the limited ability of the Nash equilibrium to rationalize observed behavior in many classes of games played by experimental subjects. This realization has led to several attempts aimed at finding tractable equilibrium...

We elicit and compare risk preferences from student subjects and subjects drawn from the general population, using the multiple price list method devised by Holt and and Laury (2002). We find evidence suggesting that students have lower relative risk aversion than others.
