| This paper proposes a new test to distinguish between the two leading theories of discrimination: preference versus information. Discrimination based on preferences occurs when people behave as if they refuse to change their stereotypes about the capabilities of discriminated individuals. Those who discriminate based on information are willing to alter their stereotypes. Using data from a quasi-experiment in South Africa, I test for discrimination against women and non-whites. The preliminary results show no discrimination against the former. In the case of racial discrimination, players' stereotypes benefit non-whites instead of white opponents, but they are reluctant to change their impression for the former. However, they are willing to change their... |

| Using a longitudinal survey of South African households over the 1993-2004 period, this paper evaluates changes in income distribution since the end of apartheid. Inequality amongst these households has markedly increased this period as initially better off households consistently improved their economic well-being. Sharp increases in measured poverty over the first half of this period were partially reversed by later improvements for some poor households. Comparisons between actual and "market-generated" income distributions suggest that these improvements were driven in part by government transfer programs. Nonetheless, the chronically poor remain a significant fraction of the total poor, and 60% of those households that were poor in 1993 are still poor... |

| Most studies measuring asymmetric adjustments in vertical price transmissions fail to provide empirical support to explain such behavior. The literature invokes theoretical models, which derive asymmetric behavior based on variables that are difficult to measure such as oligopolies' coordination policies, market imperfections or menu costs. Therefore, with no empirical support explaining the asymmetries, these studies leave no room for policy implementation. In this paper I relate asymmetric price responses to a theory of behavior under risk driven by the perishable rate of the goods. Retailers of a perishable good facing an increment in the wholesale price may decide not to increase their prices for fear of being left with a spoiled product. Using three... |

| This paper describes two problems when testing the efficiency of intra-household allocations. First, using Monte Carlo simulations I show that the test proposed for efficiency in consumption has a high type-II error, leading to a false acceptance of the hypothesis. Second, I show it is possible that even under asymmetric information the hypothesis of efficiency, incorrectly, cannot be rejected. Finally, I propose a test to account for asymmetric of information. |
