The recent massive inflow of refugees to the European Union (EU) raises a number of unanswered questions on the economic impact of this phenomenon. To examine these questions, we constructed an overlapping-generations model that describes the evolution of the skill premium and of the welfare benefit level in relevant European countries, in the aftermath of an inflow of asylum-seekers. In our simulation, relative wages of skilled workers increase between 8% and 11% in the period of the inflow; their subsequent time path is dependent on the initial skill premium. The entry of migrants creates a fiscal surplus of about 8%, which can finance higher welfare benefits in the subsequent periods. These effects are weaker in a scenario where refugees do not fully integrate into the labor market.

In urban Burkina Faso, siblings play a decisive role in local social security. Badenya, the unity of children of the same mother, compensates in particular for the economic failure of an eldest son no longer in a position to fulfill his familial duties. Although the institution of badenya is strengthened as it increasingly comes into play to help a family avoid social marginalization, it is also overburdened, which makes its future uncertain. This article enhances the anthropological understanding of kinship by focusing on sibling relationships. Findings are based on interviews conducted between 2007 and 2010 with two generations in households in Bobo-Dioulasso and on participant-observation over the course of more than a dozen research stays since 1989.

Before 1982 Mexico's welfare state regime was a limited conservative one that put priority on the social security of organized labor. But following the country's debt crisis in 1982, this regime changed to a hybrid liberal model. The Ernest Zedillo government (1995-2000) in particular pushed ahead with liberal reform of the social security system. This paper examines the characteristics and the policy making of the social security reforms in the 1990s. The results suggest that underlying these reforms was the restructuring of the economy and the need to cope with the cost of this restructuring. The paper also points out that one of the main factors making possible the rapid execution of the reforms were the weakened political clout of the officialist labor unions due to their steady breakdown during the 1990s and the increase in the monopolistic power of the state vis-a-vis the position of labor during the negotiations on social security reforms.

This paper tries to understand the current status of South African labor market, which is changing in contradictory directions, i.e. a strengthening of the rights and protection of workers at the same time as the flexibilization of employment, in the context of the characteristics of labor and social security legislation in South Africa, as well as the nature of labor and social security reforms after democratization. We put emphasis on the corporatist nature of labor policy-making as the factor influencing the course of reforms; it is argued that the apparently contradictive changes can be explained consistently by the corporatist labor policy-making process which has been practiced notwithstanding the problem of representativeness.

This paper will analyze the Menem administration's social policy reforms during the 1990s. Neo-liberal reforms in Argentina are well-known both in the economy and in the social arena, but in the latter we can discern the presence of tripartite negotiations. The form of such negotiations, the type of agreements reached as a result, and the background to those agreements will be discussed. We also pay attention to the concept of competitive corporatism, which was established under the increase in market competition brought about by globalization.
