I describe and compare sources of data on citations in economics and the statistics that can be constructed from them. Constructing data sets of the post-publication citation histories of articles published in the "Top 5" journals in the 1970s and the 2000s, I examine distributions and life...

The previously documented trend toward more co- and multi-authored research in economics is partly (perhaps 20 percent) due to different research styles of scholars in different birth cohorts (of different ages). Most of the trend reflects profession-wide changes in research style. Older...

The macroeconomic production function is a traditional key element of modern macroeconomics, as is the more recent knowledge production function which explains knowledge/patents by certain input factors such as research, foreign direct investment or international technology spillovers. This...

Relative wages have been remarkably rigid for the last two decades in Danish manufacturing despite large shifts in relative employment from unskilled labor towards skilled and educated labor. Assuming capital-skill complementarity and fixed relative wages as a consequence of labor market...

We consider a tax-funded policy of admitting and integrating asylum seekers in a country in which the incomes of the native inhabitants are differentiated; for the sake of simplicity, we assume that there are just two groups of native inhabitants: high-income natives and low-income natives. As a...

How does easing the economic integration of forced migrants affect native voting behaviors in the Global South? This paper assesses how the regularization of half a million Venezuelan forced migrants affected the electoral choices of Colombian natives by comparing election results in...

Highly-skilled migrants are becoming a more important part of the world economy and of policy debates in a diverse set of countries. The proliferation of skills around the world, increases in world trade, the growth of R&D, and the general increase in the labor market demand for diverse sets of...

In this paper, we explore empirically the role of openness, technology and labour market rigidity in the determination of the effect of the exchange rate on employment in Portugal. We develop an index that allows us to measure labour market flexibility at the sector level. This index shows that...

Immigrants can increase international trade by shifting preferences towards the goods of their country of origin and by reducing bilateral transaction costs. Using geographical variations across US states for the period 1970 to 2005, we quantify the impact of immigrants on intermediate goods...

Increasing wage inequality between similar workers plays an important role for overall inequality trends in industrialized societies. To analyze this pattern, we incorporate directed labor market search into a dynamic model of international trade with heterogeneous firms and homogeneous workers....
