If the consumers risk aversion behavior varies intertemporally and if the risk aversion coefficient on future consumption becomes very large, the consumer tends to aim at a fixed future consumption target. A by-product is a reinterpretation of subsistence theories of consumption.

The paper argues that economism and, in particular, the individual drive to maximize utility and amass profit are not enough to ensure the efficient functioning of an economy; and that even for elementary economic activities, such as trade, exchange and contracting to occur smoothly, it is...

We develop a tractable model of competition among motivated MFIs. We find that equilibria may or may not involve double-dipping (and consequently default), with there being double-dipping whenever the MFIs are very profit-oriented. Moreover, in an equilibrium with double-dipping, borrowers who...

Does the accuracy of verdicts improve or worsen if individual jurors on a panel are barred from deliberating prior to casting their votes? I study this question in a model where jurors can choose to exert costly effort to improve the accuracy of their individual decisions. I find that, provided...

We examine affirmative action, class-based (CAA), as well as identity-based (IAA), in an economy with income heterogeneity and diverse identity groups. We establish that with class-based affirmative action there exists an equilibrium that is colour-blind, i.e. the poor face the same standards...

It has long been recognized that some plaintiffs sue defendants out of malice, but malicious litigation has not been previously modeled in the law and economics literature. I construct a simple model of malicious litigation, wherein malice is defined by the plaintiff’s obtaining some utility...

I unify the following (1) men face paternity uncertainty while women do not face maternity uncertainty, (2) putative fathers and paternal kin care about true paternity, (3) paternity confidence is systematically lower in matrilocal cultures than in patrilocal ones, (4) inheritance tends to be...

In the traditional model of Bertrand price competition among symmetric firms, there is no restriction on the number of firms that are active in equilibrium. A symmetric equilibrium exists with the different firms sharing the market. I show that this does not hold if we preserve the symmetry...
