This paper shows that between 1975 and 2005, Sweden exhibited a pattern of job polarization with expansions of the highest and lowest paid jobs compared to middle-wage jobs. The most popular explanation for such a pattern is the hypothesis of ‘task-biased technological change’, where technological progress reduces the demand for routine middle-wage jobs but increases the demand for non-routine jobs located at the tails of the job-wage distribution. Our estimates, however, do not support this explanation for the 1970s and 1980s. Stronger evidence for task biased technological change, albeit not conclusive, is found for the 1990s and 2000s. In particular, there is both a statistically and economically significant growth of non-routine jobs and a decline of routine jobs. Results for wages are, however, mixed; while task-biased technological change cannot explain changes in between-occupation wage differentials, it does have considerable explanatory power for changes in within-occupation wage differentials.

Calibrations of models related to life-cycle behavior of consumption and saving often invoke the important assumption of a unit root in individuals' labor-income process. We for the first time test this assumption using methods for univariate time series. Based on longitudinal register data from 1968 to 2005, we first estimate an autoregressive model for each individual using a method for approximately median-unbiased estimation. We then exploit the resulting distribution of the individual-specific estimates to draw inference about the presence of a unit root. Results indicate that earnings for the representative worker are governed by a process where shocks to earnings have moderate persistence and are both economically and statistically significantly different from having permanent effects. These results question the heavy use of unit-root processes for earnings.

This paper disentangles the effect of inequality in permanent and transitory wages on hours worked by, first, estimating the two components for Swedish industries and, second, using the resulting estimates as explanatory variables in an hours-worked equation. Consistent with Bell and Freeman’s (2001) inequality-hours hypothesis, permanent wage differentials are found to have a positive effect on individuals’ hours of work while transitory wage differentials have no effect. However, the analysis also shows that, in estimated hours-worked equations, inequality in observed wages is potentially a good approximation for inequality in permanent wages.

The informational value of the aggregate US unemployment rate has recently been questioned because of a unit root in the labor-force participation rate; the lack of mean reversion implies that long-run changes in unemployment rates are highly unlikely to reflect long-run changes in joblessness. This note shows that this critique also extends to unemployment rates for sub-populations, such as prime-aged males. (C) 2012 Elsevier B.V. All rights reserved.

This article investigates whether the US unemployment rate is best described as a unit-root or mean-reverting process. An out-of-sample forecast exercise is conducted in which the performance of an autoregressive (AR) model with an imposed unit root is compared with that of a mean-reverting AR model. A bootstrap distribution for the relative root mean square forecast error is generated and provides strong support for mean reversion in the US unemployment rate.

This paper investigates the relevance of unemployment hysteresis in seventeen OECD countries. We employ an out-of-sample forecast exercise in which a mean-reverting autoregressive model is compared to an autoregressive model with an imposed unit root. A substantial difference in forecasting performance between the two models is established for many countries, but the results are mixed in their strength. The evidence for unemployment hysteresis in Austria, Finland, Iceland, Israel, Italy, Japan and Sweden is, however, convincing. For no country can unambiguous support for a mean reverting unemployment rate be found.

Using a large individual longitudinal database, I decompose the cross-sectional variance of male annual earnings in Sweden between 1960 and 1990 into persistent and transitory components. The persistent variance displays a downward trend during the whole sample period, but with the rate of decline more rapid up until the early 1980s than afterwards. The transitory variance has increased from 1960 until the early 1970s, decreased slightly until the late 1970s, and then risen again during the second half of the 1980s. An important lesson from these results concern the interpretation of the rise in cross-sectional inequality observed after the 1983 breakdown of centralized bargaining in Sweden. While it has often been presumed that this growth reflected increased returns to skills, this study shows that it was in fact due to increased transitory earnings fluctuations.

We present new evidence on the influence of income inequality on generalized trust. Using individual panel data from Swedish counties together with an instrumental variable strategy, we find that differences in disposable income, and especially differences among people in the bottom half of the income distribution, are associated with lower trust. The relationship between income inequality and trust is particularly strong for people with a strong aversion against income differentials. We also find that the proportion of people born in a foreign country is negatively associated with trust.
