An evolutionary model of the product life cycle is applied to derive the experience curve and the market size of (expensive) durable goods. The experience (learning) curve suggests that the real costs per unit decrease with an increasing cumulative output (Henderson's law). Based on the idea...

This paper discusses the links between earnings, consumption and economic welfare inequality. It places emphasis on the role of leisure and labor supply in the assessment of cross-household inequality and argues that the documented increase of such inequality has its origin in the labor market....

This paper argues critically the issue of choices and rationality in economic models through a multidisciplinary analysis. First, the analysis aims at highlight the scientific contributions of psychology in economics, since psychology and the related approach of cognitive economics has made more...

The paper critically discusses the issue of rationality and choices in economics in both the behavioural and evolutionary approaches. Our study aims, on the one hand, to highlight the scientific contributions of psychology in economics, since psychology, and with it the theoretical approach of...

Is it better to apply effort to increase personal consumption, or control what one wants? The model presented here provides a characterization of demand for self control, namely, its responsiveness to price and risk. Unlike most other models of self control, the model does not identify self...

The article discusses consumption as a social process that is a part of social provisioning and is in an evolutionary interplay with other social processes. The discussion is grounded in, but is not limited to the contributions of Thorstein Veblen. The first section delineates social...

This work considers optimization problems under Rawls and maximin with multiple discount factors criteria. It proves that though these criteria are different, they have the same optimal value and solution.

We develop a turnpike theory for a class of dynamic general equilibrium models where total demand function satisfy monotonicity conditions. As special cases, we receive well known results about asymptotic behavior of optimal paths.

This article studies an inter-temporal optimization problem using a criterion which is a combination between Ramsey and Rawls criteria. A detailed description of the saving behaviour through time is provided. The optimization problem under $\alpha-$\emph{maximin} criterion is also considered...
