Do Foreign Experts Increase the Productivity of Domestic Firms?

While most countries welcome (and some even subsidise) high-skilled immigrants, there is very limited evidence of their importance for domestic firms. To guide our empirical analysis, we first set up a simple theoretical model to show how foreign experts may impact on the productivity and wages of domestic firms. Using matched worker-firm data from Denmark and a difference-indifferences matching approach, we then find that firms that hire foreign experts – defined as employees eligible for reduced taxation under the Danish "Tax scheme for foreign researchers and key employees" – both become more productive (pay higher wages) and increase their exports of goods and services.foreign experts, export, immigrants, productivity, difference-in-differences matching

Should Native Workers Welcome Foreign Workers in Upturns ?

In this paper, we show that the welfare implications of immigration which takes place in upturns, and may be partly reversed in downturns, are very different from the implications of immigration usually found in static models. Abstracting from any gains to capital owners and native workers due to complementarities, we find that (especially temporary) immigration may still benefit native workers in a European type of labour market where minimum wages may bind in downturns. However, in the presence of hiring costs, these effects may be reversed. Thus, promoting temporary immigration schemes may lead to adverse consequences if they also increase the costs of hiring foreign labour

Human Capital and Wages in Exporting Firms

This paper studies the link between a firms education level, export performance and wages of its workers. We argue that firms may escape intence competition in international markets by using high skilled workers to differentiate their products. This story is consistent with our empirical results. Osing a very rich matched worker-firm longitudinal dataset we find that firms with high export intensities pay higher wages. However, an interaction term between export intensity and skill intensity has a positive impact on wages and it absorbs the direct effect of the export intensity. That is, we find an export wage premium, but it accrues to workers in firms with high skill intensities.

Labour Market Implications of a Compressed Wage Structure when Education and Training are Endogenous

We consider the economic implications of a compressed wage structure which is exogenously determined by institutions. An important feature of our analysis is that human capital is endogenous and can be achieved either as formal education or as informal training within firms after entering the labour market. While institutional wage compression decreases the incentives of individuals to become educated, it increases the incentives of firms to invest in training. As a result, the net effects of wage compression on the aggregate human capital level and GDP are ambiguous. Moreover, with wage compression, a skillbiased technological change may cause wage inequality to decrease.

Product Market Integration, Comparative Advantages and Labour Market Performance

Product Market Integration, Comparative Advantages and Labour Market Performance* In a two-country model with trade driven by comparative advantages, it is considered how imperfectly competitive labour markets are affected by lower frictions in international goods trade. Easier goods trading is equivalent to increased mobility of employment across countries and thus a change in the trade-off between wages and employment faced by wage setters. While the effects of product market integration on the trade-off between wages and employment in general is ambiguous, it is shown that product market integration works like a general improvement in productivity via the specialization it allows through trade. Unambiguously, real wages and employment and welfare improve upon reductions in trade frictions, and therefore workers are better off irrespective of whether the market power of unions is enhanced or muted.
