We build a life cycle model of labor supply that incorporates changes along both the intensive and extensive margin and use it to assess the consequences of changes in tax and transfer policies on equilibrium hours of work. We find that changes in taxes have large aggregate effects on hours of work. Moreover, we find that there is no inconsistency between this result and the empirical finding of small labor elasticities for prime age workers. In our model, micro and macro elasticities are effectively unrelated. Our model is also consistent with other cross-country patterns.

The paper describes the Swedish wage distribution and how it correlates with worker mobility and plant-specific factors. It is well known that wage inequality has increased in Sweden since the mid-1980s. However, little evidence has so far been available as to whether this development reflects increased dispersion between plants, between individuals in the same plant, or both. We use a new linked employer-employee data set and discover that a trend rise in between-plant wage inequality account for the entire increase in wage dispersion. This pattern, which remains when we control for observable individual human capital characteristics, may reflect increased sorting of workers by skill levels and/or increased scope for rent sharing in local wage negotiations. Our discussion suggests that both factors may have become more important.

We incorporate trade imbalances into a quantitative model of bilateral trade in manufactures, dividing the world into forty countries. Fitting the model to 2004 data on GDP and bilateral trade we calculate how relative wages, real wages, and welfare would differ in a counterfactual world with all current accounts balancing. Our results indicate that closing the current accounts requires modest changes in relative wages. The country with the largest deficit (the United States) needs its wage to fall by around 10 percent relative to the country with the largest surplus (Japan). But the prevalence of nontraded goods means that the real wage in Japan barely rises while the U.S. real wage falls by less than 1 percent. The geographic barriers implied by the current pattern of trade are sufficiently asymmetric that large bilateral deficits remain even after current accounts balance. The U.S. manufacturing trade deficit with China falls to $65 billion from its 2004 level of $167 billion.
