This paper analyzes sin goods consumption when individuals exhibit present-focused preferences. It considers three types of present focus: present-bias with varying degrees of naiveté, Gul-Pesendorfer preferences, and a dual-self approach. We investigate the incentives to deviate from healthy...

In this paper, we study methods of inferring a decision maker's true preference relation when observed choice data reveal a nontransitive preference relation due to choice mistakes. We propose some sensible properties of such methods and show that these properties characterize a unique rule of...

Current neoclassical microeconomic theory of rational consumer behavior affirms a unique consumer price-quantity relationship under conditions associated with monopolistic competition. Inverse demand will be just as own-price elastic as demand in the neighborhood of the limit state, while demand...

The paper proposes a method of transforming a possibly cyclic preference relation of a decision maker into a transitive binary relation, which is called the transitive core. The characterizing properties of such a transformation is given. In addition, the transitive core is applied to...

We show that the Hicksian welfare measures of compensating variation and equivalent variation coincide if one of them is evaluated at a compensated income. The measures are nondecreasing in income if the varied attribute and income are complementary, and indirect utility is concave in income....

Current time allocation and household production models face three major weaknesses: First, they only describe the average time allocation. Thus, information about the order of activities is lost. Therefore, it is impossible to describe the influence of activities on later ones. Such...

Neoclassical economics assumes that individuals have stable and context-independent preferences, and uses preference-satisfaction as a normative criterion. By calling this assumption into question, behavioural findings cause fundamental problems for normative economics. A common response to...
