Cosmopolitan or anxious? In order to test the influence of conflicting aspects of identity, German respondents were asked about their attitude towards a Syrian refugee the description of whom was varied in various domains (N=662). Once the refugee is described as being aware of as well as open...

We investigate the export-enhancing effect of foreign workers at the firm level. We first develop a theoretical framework of heterogeneous firms, assuming that foreign workers allow for productivity gains and convey valuable information on foreign markets. We illustrate that foreign workers...

This paper compares two prominent empirical measures of individual risk attitudes - the Holt and Laury (2002) lottery-choice task and the multi-item questionnaire advocated by Dohmen, Falk, Huffman, Schupp, Sunde and Wagner (2011) - with respect to (a) their within-subject stability over time...

This paper models the welfare consequences of social fragmentation arising from technological advance. We start from the premise that technological progress falls primarily on market-traded commodities rather than prosocial relationships, since the latter intrinsically require the expenditure of...

This paper proposes a simple framework to model social preferences in a game theoretic framework which explicitly separates economic incentives from social (context) effects. It is argued that such a perspective makes it easier to analyse contextual effects. Moreover, the framework is used to...

I develop a model of endogenous economic growth and search and matching frictions in the labor market. I study the effect of trade liberalization between two identical economies on unemployment. I solve for two versions of the growth model, the first one where trade liberalization has only a...

This paper explores the role of pooled-producer, e.g. private label, trade intermediation in shaping the range and diversity of exports. Direct sales maintain a firm's unique product characteristics ('brand equity'), whereas trade through an intermediary can take two forms - either a wholesaling...

We develop a new model of trade in which educational institutions drive comparative advantage and determine the distribution of human capital within and across countries. Our framework exploits a multiplicity of sectors and the continuous support of human capital choices to demonstrate that...

We develop a dynamic general equilibrium trade model with comparative advantage, heterogeneous firms, heterogeneous workers and endogenous firm entry to study wage inequality during the adjustment after trade liberalization. We find that trade liberalization increases wage inequality both in the...

We introduce unemployment and endogenous selection of workers into different skill-classes in a trade model with two sectors and heterogeneous firms. This allows us to study the distributional consequences and the skill-specific unemployment effects of trade liberalization. We show that the...
