Multidimensional Pigou–Dalton transfers and social evaluation functions

We axiomatize, in the multidimensional case, a social evaluation function that can accommodate a natural Pigou–Dalton principle and correlation increasing majorization. This is performed by building upon a simple class of inframodular functions proposed by Müller and Scarsini under risk.     

Subsidizing wages or supplementing transfers? The politics and ambiguity of in-work benefits

In-work benefits (IWB) have become mainstream social policy programmes in modern welfare states. Aimed at employment promotion as well as poverty reduction, their introduction and expansion have been supported by both centre-right and centre-left governments. However, the article argues that policy positions towards IWB are essentially unstable. Political preferences can alter fast, with the same actors advocating IWB growth at one time and containment at another. In part, this is influenced not only by prevailing socio-economic conditions but also by the institutional shape of IWBs, their interaction with complementary policies, and their inherently ambiguous nature. Characterized by multiple aims, IWBs occasionally offer political opportunities but often create challenges and even confound policymaking. Thus, the understanding of the politics of IWB requires a careful consideration of the particular properties of concrete IWBs and the ways in which they relate to other policy arenas. The article discusses this with reference to relevant debates and reforms in Germany.     

Has the redistributive effect of social transfers and taxes changed over time across countries?

In most Member countries of the Organisation for Economic Co‐operation Development (OECD), the income gap between rich and poor has widened over the past decades. This article analyses whether and to what extent income taxes and social transfers have contributed to this trend. Has the redistributive impact of different social programmes changed over time? We use microdata from the LIS Cross National Data Center in Luxembourg for the period 1982–2014 and study both the total population and the working‐age population. In contrast to the results of some other studies, especially by the OECD, we do not find that redistribution has declined. Tax‐benefit systems around 2013 are more effective at reducing income inequality compared to the mid‐1980s and the mid‐1990s, especially among the total population. Changes in social programmes are not a driver of greater income inequality across the countries included in this study.     

How much is too much: Does the size of income support transfers affect labor supply?

Cash transfer programs pursue mainly protective objectives, but can also impact rural livelihoods by inducing investments in productive activities and changing household labor allocation. We adopt a continuous treatment approach to quantify how households’ labor supply responds to transfer size. We find a shift from paid labor to own farm labor and find that the transfer size is well within a level that would have disincentive effects on time spent on own farm activities. The switch from paid to own farm labor occurs at lower levels of transfers for labor-constrained households, and at higher levels for non-labor constrained households.     

Does family still matter? Public and private transfers in emerging welfare state systems in a comparative perspective

Kim JW, Choi YJ. Does family still matter? Public and private transfers in emerging welfare state systems in a comparative perspective Int J Soc Welfare 2011: 20: 353–366 © 2010 The Author(s), International Journal of Social Welfare © 2010 Blackwell Publishing Ltd and the International Journal of Social Welfare. While the role of the family has been a distinctive feature of East Asian welfare systems, rapid social policy development and reforms in South Korea and Taiwan over the last two decades have led to an increase in public welfare. Yet, despite a growing number of studies, little is known about the role of family support – private transfers – and public programmes in the performance of state welfare. This article reports on a comparative analysis of the role of public and private transfers aimed at poverty and inequality reduction in 12 Western and two East Asian states employing the Luxemburg Income Study data set. Results indicate that, in contrast to the West, private transfers that rest primarily on family support remain more important than public transfers in reducing income inequality and poverty in South Korea and Taiwan.
