Skill Polarization in Local Labour Markets under Share-Altering Technical Change
AbstractThis paper considers the “share-altering” technical change hypothesis in a spatial general equilibrium model where individuals have different levels of skills. Building on a simple Cobb-Douglas production function, our model shows that the implementation of skill-biased technologies requires a sufficient proportion of highly educated individuals. Moreover, areas that experiment this kind of technical change will initially exhibit a rise in local skill premia, but such a trend tends to be reverted over time due to labour mobility. Also, when technical progress is such to disproportionately replace middle-skill jobs, the local distribution of skill will exhibit “fat-tails”, where the proportion of both highly skilled and low-skilled workers increases. These predictions are consistent with recent existing evidence.
