We examine the economy-wide impact of the child support grant (CSG) on the South African economy using a bottom-up/top-down approach. This allows us to estimate the potential effects on households’ welfare and on the economy following a change in the CSG. Three simulations are presented, in...

We develop a reciprocity-based model of wage determination and incorporate it into a moder dynamic general equilibrium framework. We estimate the model and find that, among potential determinants of wage policy, rent-sharing (between workers and firms) and a measure of wage entitlement are...

Inflation definitely has costs, but they remain difficult to quantify for rates below 10-15 per cent. Aiming for a low rate of inflation, as Canada has done in the last 20 years, carries with it various risks, such as debt deflation, reduced flexibility of interest rates, and downwardly rigid...

We estimate a stochastic life-cycle model of endogenous health spending, asset accumulation and retirement to investigate the causes behind the increase in health spending and longevity in the U.S. over the period 1965-2005. We estimate that technological change and the increase in the...

We combine the choice data of proposers and responders in the ultimatum game, their expectations elicited in the form of subjective probability questions, and the choice data of proposers ("dictators") in a dictator game to estimate a structural model of decision making under uncertainty. We use...

We investigate how to make poverty comparisons using multidimensional indicators of well-being, showing in particular how to check whether the comparisons are robust to aggregation procedures and to the choice of multidimensional poverty lines. In contrast to earlier work, our methodology...

Variations in aggregate poverty indices can be due to differences in average poverty intensity, to changes in the welfare distances between those poor of initially unequal welfare status, and/or to emerging disparities in welfare among those poor of initially similar welfare status. This note...

We propose a general class of indices of horizontal inequity that complements existing classes of progressivity and vertical equity indices. The class of horizontal inequity indices can also correct for biases in measuring a general class of inequality measures. We illustrate our results using...

We pursue the analysis of the Path Serial Cost Sharing Rule by examining how the cost share of an agent varies with respect to its own demand and the one of other agents. We also provide bounds for cost shares under an appropriate assumption on the cost function.<P> On poursuit l'analyse de la...</p>

We provide an axiomatization of Yitzhaki’s index of individual deprivation. Our result differs from an earlier characterization due to Ebert and Moyes in the way the reference group of an individual is represented in the model. Ebert and Moyes require the index to be defined for all logically...
