In this paper, we consider the problem of designing an integrated assembly line when many skilled and unskilled workers are available. This problem arises when there are certain limited resources available such as skilled workers in which the operation time for every task is different depending on assignment of the unskilled workers to help the skilled workers. The selection of both skilled wor...

This paper address a special class of generalized assembly line balancing in which it is assumed that there are two groups of workers: skilled and unskilled ones. The skilled workers are hired permanently while the unskilled ones can be hired temporarily in order to meet the seasonal demands. It is also assumed that more than one worker may be assigned to each workstation. To show the adv...

This paper proposes and evaluates a mechanism through which imports of unskilled intermediates (offshoring) benefit both skilled and unskilled workers by inducing capital deepening and innovation in developed countries. Data for manufacturing industries in the US over 1974-2005, show that although offshoring increases inequality between skilled and unskilled workers, unskilled workers also gain...

The paper explores the interaction between sector-specific human capital accumulation and sector-specific productivity or demand shocks. Our objective is to better understand the determinants of skill and experience premia, the costs of displacement for workers with long job tenure, and the nature of unemployment among such workers. For example, our model suggests why skilled workers can remain...

We study a model of tax competition between two countries when both skilled and unskilled workers make their migration decisions simultaneously and wages are endogenously determined. If both factors of production are allowed to migrate freely and when the demand for skilled labor is not so elastic, the problem typically predicted in the literature of tax competition that increased mobility of p...

In this paper, we introduce two sources of unemployment in a two-factor general equilibrium model: search frictions and fairness considerations. We …nd that a binding fairwage constraint increases the unskilled unemployment rate and can at the same time lead to a higher unemployment rate for skilled workers, as compared to an equilibrium where fairness considerations are absent or non-binding. ...

This study adopts a GNP function approach in order to examine the impact of migrant labour on domestic factors of production in the United Kingdom. We also examine the relationship between imports and migrants, which are two different facets of globalisation. We find that an increase in the number of unskilled migrants reduces the wages of unskilled domestic workers. However the quantitative im...

Using a three-sector general equilibrium model with non-traded goods, we investigate the impact of foreign direct investment on the real wages of skilled and unskilled workers. We show that foreign direct investment increases the real wages of skilled and unskilled workers, but widens the gap between the two under plausible conditions. JEL: F10, F11, F21

This paper seeks to identify the causal effect of foreign acquisitions on wages of skilled and unskilled workers, using difference-in-differences propensity score matching estimators. Our results suggest that there is substantial heterogeneity in the post-acquisition wage effect depending on the nationality of the foreign acquirer and the skill group of workers. We find sizable post acquisition...
