Using annual data for 21 OECD countries we provide evidence of remarkable mispricing of sovereign bonds for the so-called GIIPS countries before the start of the financial crisis. Our results also qualify the view of pronounced overpricing in the crisis. In detail, we find: (i) Since the 1980s...

We demonstrate that a rank-preserving transfer from a richer individual to a poorer individual can exacerbate income inequality (when inequality is measured by the Gini coefficient). This happens when individuals' preferences depend negatively not only on work time (effort) but also on low...

In this paper we study the impact of the international migration of unskilled workers on skill formation and the average skill level in the home country. We analyze what appears to be the least threatening scenario from the point of view of its effect on the supply of skills at home: namely,...

This paper analyzes the role of ethnic communities in shaping the recent immigration boom to Spain. We find that ethnic communities exerted a strong positive effect on the scale and a strong negative effect on the skill structure of this immigration. Unlike previous studies, we explicitly...

We examine the interplay between changes in the functional distribution of income and the distribution of market income among households. We use micro data from the German Socio-Economic Panel as well as macro data from the German Federal Statistical Office from 2002 to 2008. We categorize and...

This paper first describes the ingredients the present crisis in the euro zone and then evaluates the key options that policy makers face in resolving the crisis and avoiding similar crises in the future. I argue that the crisis should not be seen as caused by government profligacy alone. In...

We investigate the impact of the imposition of sanctions for employing illegal migrants on the welfare of native workers. Our analysis is based on the premise that in response to such sanctions, managers in a firm may be reassigned from supervision of production to verification of the legality...

Insufficient capital buffers of banks have been identified as one main cause for the large systemic effects of the recent financial crisis. Although higher capital is no panacea, it yet features prominently in proposals for regulatory reform. But how do increased capital requirements affect...

This paper derives a new effect of trade liberalisation on the quality of the environment. We show that in the presence of heterogeneous firms the aggregate volume of emissions is influenced not only by the long-established scale effect, but also by a reallocation effect resulting from an...

Arkolakis, Costinot and Rodriguez-Clare (ACR, 2012) prove that, conditional on the change in openness, the welfare gains from foreign trade reforms are quantitatively identical across single-sector trade models with radically different micro-foundations. We generalize this result to domestic and...
