In this paper we consider a class of economies with a finite number of divisible commodities, linear production technologies, and indivisible goods, and a finite number of agents. This class contains several well-known economies with indivisible goods and money as special cases. It is shown that...

We study a class of symmetric, quasi-homothetic preferences that result in demands logarithmic in own prices when these have a negligible impact on aggregate price indices (as in monopolistic competition models). Thus marginal revenues are computationally friendly, and decreasing whenever...

We introduce a novel and convenient approach to utility modeling. In doing so, we present a general utility function in a very simple exact form. Furthermore, we develop a method to (accurately) measure preferences without any utility data. We also devise a method to measure the marginal...

Utility should be a function consisting of two autonomous sections both positive and negative, that needs to be configurable to the individuals it is designed to represent. This is achieved through the target by which individuals measure their investments against as well as their individual...

Presently, it is widely accepted that the particular utility function first reported by Wold and Juréen (1953), and later by Weber (1997), is capable of generating a Giffen good. This note challenges this view by showing that this Wold-Juréen (1953) utility function is not well-behaved, and...

The “surprise value” of many economic observations makes our discipline quite interesting for many students. One such anomaly is that providing “free” education in an effort to reduce the number of dropouts can often result in a lower level of educational quality purchased. This result...

Does risk attitude (aversion or attraction) vary with the level of the income at risk? About half of our subjects chose to insure all levels, whereas another half chose instead not to insure low levels, but to insure high levels
