In this paper, we describe a novel iterative procedure called SISTA to learn the underlying cost in optimal transport problems. SISTA is a hybrid between two classical methods, coordinate descent ("S"-inkhorn) and proximal gradient descent ("ISTA"). It alternates between a phase of exact...

This paper presents a tractable framework for studying frictionless matching in school, work, and marriage when individuals have heterogeneous social and cognitive skills. In the model, there are gains to specialization and team production, but specialization requires communication and...

This study charts the differences between the sickness absence of immigrants and Swedes during a period when a flourishing labour market in the beginning of the 1990s turned into a tense and problematic one. We consider not only human capital factors for various immigrant groups and natives, but...

In this paper, we define a new class of richness measures. In contrast to the often used headcount, these new measures are sensitive to changes in rich persons' income and therefore allow for a more sophisticated analysis of richness. We demonstrate the application of these new measures to...

Today's labor-scarce economies have open trade and closed immigration policies, while a century ago they had just the opposite, open immigration and closed trade policies. Why the inverse policy correlation, and why has it persisted for almost two centuries? This paper seeks answers to this dual...

The paper reviews national and international experiences with different combinations of in-work benefits, subsidized employment, statutory minimum wages and implicit minimum wages defined by social assistance provisions. It calls for a cautious approach regarding the introduction of additional...

In most destination countries, immigration policies are increasingly tilted toward the most skilled individuals. Whether this shift hurts economic prospects in sending countries, as argued by the traditional brain drain literature, is somewhat controversial. The most recent literature has...

In this research, the relationship between globalisation and poverty and income inequality is determined. A whole new globalisation index has been constructed based on data covering a large sample of 65 developing countries. The index is based on the globalisation index proposed by A.T. Kearney...

We study the process of endogenous democratization from inefficient oligarchic systems in an economy where heterogeneous individuals can get involved in predation activities. The features of democracies are shown to be crucially related to the conditions under which democratization initially...
