We provide a nonparametric 'revealed preference' characterization of rational household behavior in terms of the collective consumption model, while accounting for general (possibly non-convex) individual preferences. We establish a Collective Axiom of Revealed Preference (CARP), which provides...

The paper contributes to the literature on the relation between structural changes in demand and supply and growth. We develop a macro-economic model with agent-based micro-foundations that articulates the links between production and organisational structures on the supply side, and the...

We extend the classic Merton (1969, 1971) problem that investigates the joint consumption-savings and portfolio-selection problem under capital risk by assuming sophisticated but time-inconsistent agents. We introduce stochastic hyperbolic preferences as in Harris and Laibson (2013) and find...

We propose a consistent utility-based framework to jointly explain a household's decisions on purchase incidence, brand choice and purchase quantity. The approach differs from other approaches, currently available in the literature, as it is able to take into account consumption dynamics. In the...

The paper argues that when a consumer searches for a lower price, a satisficing decision procedure equalizes marginal costs of search with its marginal benefit. The consumer can maximize the utility of his consumption-leisure choice with regard to the equality of marginal values of search....

Strong growth in disposable income has driven, and is still driving, consumption to unprecedented, but not sustainable levels. To explain the dynamic interplay of needs, need satisfaction, and innovation underlying that growth a behavioral theory of consumption is suggested and discussed with...

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 study invents four types of non-monotonic utility functions that suit the sufficiency economy. With these utility functions, an individual may not get higher utility when consume more goods. Therefore, an individual requires an optimal level of income rather than a maximized level of income...

Growth theory has mainly focused on process innovation, either through an increase in quality of the product or a reduction on the cost. The main contributions in growth theory that includes product innovation has been done in the Dixit and Stiglitz framework. This framework works with...

We study the optimal provision of unemployment insurance (UI) in a framework that distinguishes between consumption and expenditure. We derive a "sufficient statistics" formula for optimal UI that is expressed terms of observable variables and can therefore be used in applied work. Recent...
