Résumé / Abstract Nous démontrons que si l'utilité est une fonction de la richesse relative, peut-être à cause de la recherche du standing, alors, sous certaines hypothèses concernant la courbature de la fonction d'utilité et de la fonction de production, les gens pauvres peuvent rattraper les gens riches. Nous donnons des conditions suffisantes pour que la distribution de richesse finale soit indépendante de la distribution initiale, ainsi que les conditions suffisantes pour la stabilité au sens du point de selle. We show that, if relative wealth appears in the utility function, for example due to status seeking, then under certain conditions on the curvature of the utility function and the production function, the poor will eventually catch up with the rich. We give sufficient conditions for the final distribution of wealth to be independent of the initial distribution, and conditions for saddlepoint stability in a two-class model.

Which OIC countries are catching up? Time Series Evidences with Multiple Structural Breaks

Abstract In this paper, income per capita convergence hypothesis is tested in selected OIC countries. For this purpose, we use the time series model and univariate KPSS stationary test with multiple structural breaks (Carrion-i-Silvestre et al. (2005)) over the period 1950-2008. The results show that most OIC countries could not catch up toward USA. Although because of some positive term of tra...

Which Countries are Catching up? New Evidences Using Flexible Fourier Stationary Test

In this paper, we tested the catching-up hypothesis toward the USA using Becker et al. (2006) flexible Fourier KPSS stationary test over the period 1960-2009. The mentioned test could control for unknown number and form of structural breaks using a selected frequency component of a Fourier function. Our results show almost poor countries stay poor and almost rich countries stay rich. South Kore...
