We study differences in the effects of prices, non-price promotions, and brand line length on brand shares at different retail formats. Our conceptual framework rests on the presence of trip level fixed and category level variable utility components and shows how the trade-off between these...

The widely-used estimator of Berry, Levinsohn and Pakes (1995) produces estimates of consumer preferences from a discrete-choice demand model with random coefficients, market-level demand shocks and endogenous prices. We derive numerical theory results characterizing the properties of the nested...

This paper develops a novel approach to modeling references in monopolistic competition models with a continuum of goods. In contrast to the commonly used CES preferences, which do not capture the effects of consumer income and the intensity of competition on equilibrium prices, the present...

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

We propose a formal description of individual preferences that captures a subsistence requirement in consumption in an otherwise standard constant-elasticity-ofsubstitution (CES) utility specification. We study how substitutability between the subsistence good and another good depends on the...

Using a framework that distinguishes short-term consumer preferences, individual reflective preferences and political preferences, we discuss from a constitutional economics perspective whether individuals find it in their common constitutional interest to endow representatives and bureaucrats...

Many studies document failures of expected utility’s key assumption, the independence axiom. Here, we show that independence can be decomposed into two distinct axioms - betweenness and homotheticity - and that these two axioms are necessary and sufficient for independence. Thus, independence...

Strong growth in disposable income has inflated consumption to unprecedented, but not sustainable levels. In this process consumer behavior has been changing. To explain the driving forces of this development, the paper introduces a theory of evolving consumer preferences that is molded in an...

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...
