Earlier work has shown that procrastination can be explained by quasi-hyperbolic discounting. We present a model of effort choice over time that shifts the focus away from completion to performance on a single task. We show that quasi-hyperbolic discounting is detrimental for performance. More...

This paper deals with different concepts of income elasticities of demand for a heterogenous population and the relationship between individual and aggregate elasticities is analyzed. In general, the aggregate elasticity is  not equal to the mean of individual elasticities. The difference...

In this paper I analyse a labour market where the wage is endogenously determined according to an Efficient Bargaining process between a firm and a labour union whose members are partitioned into two social groups: the old and the young. Furthermore, I exploit the Single-Mindedness theory, which...

The objective of this paper is to study the implementation of an integrated system of information, based on Geographic Information Systems (GIS) technologies, on the fossil fuels market that can bring economic benefits to the consumers, create conditions for a more effective interview of the...

Beckmann's interaction model has each resident touching base in face-to-face activity with every other resident at the other's residence per unit time. We re-work his resulting ''interaction city'' with each resident ''operating with'' a Cobb-Douglas utility function. Similar but somewhat...

This paper builds a two-country-two-sector trade model with a monopolistically competitive sector and non-homothetic preferences. It assumes the existence of two types of goods: necessities (which are homogeneous) and luxuries (which are differentiated) and heterogeneous labor. The implications...

Our paper empirically considers two general hypotheses related to the literature of behavioral economics. First, we test the null hypothesis that individuals behave, on average, in a manner more consistent with the rational expectations hypothesis than with the idea of self-control in the face...

This paper studies whether anomalies in consumption can be explained by a behavioral model in which agents make predictable errors in forecasting income. We use a micro-data set containing subjective expectations about future income. The paper shows that, the null hypothesis of rational...

This paper attempts a broad appraisal of the literature on macro consumption function in Islamic economics. It starts with a brief look at the microelements of the concept and clears several cobwebs concerning wants and needs, scarcity of resources, the basket of goods, and the efficacy of...

This paper considers the derivation of new demand systems from existing ones through replacing an indirect utility function ) , ( y U p by } ) / ( , { j y p y y U j j â ã Ó . p , where p is a vector of prices and y is income. This is a generalisation of Gorman translation ) , ( j j p y U ã...
