Understanding wage mobility and its link with the evolution of cross-sectional earnings inequality is important from a welfare perspective, particularly given the large variety in national cross-sectional wage inequality. This is highly relevant in the context of the changes that took

The first limitation is the inability to incorporate individual heterogeneity as every agent is sharing the same parameters of the utility function. The second one is the strong assumption that individuals make decisions in a world of perfect certainty. Essentially, this paper offers an extension of marginal-utility-of-wealthconstant labour supply functions known as "Frisch functions" under certainty and uncertainty with homogenous and heterogeneous preferences. Two alternative models are proposed for capturing individual heterogeneity. First, a "fixed effect vector decomposition" model, which allows the individual specific effects to be correlated with the explanatory variables included in the labour supply model, and second, a mixed fixed and random coefficient model, which incorporates a higher degree of individual heterogeneity by specifying individual coefficients. Uncertainty is controlled for by introducing an expectation correction into the model. The validation of each simulation model is realized in comparison with the standard Heckman model. The lifetime models based on the fixed effect vector decomposition yield the most stable and unbiased simulation results, both under certainty and uncertainty. Due to its improved accuracy and stability, this lifetime labour supply model is particularly suitable for enhancing the performance of the pension models, thus providing a better reference for policymaking.

To what extent does earnings mobility work to equalize/disequalize longerterm earnings relative to cross-sectional inequality and how does it differ across the EU? Our basic assumption is that mobility measured over a horizon of 8 years is a good proxy for lifetime mobility. We used the Shorrocks (1978) and the Fields index. Moreover, we explored the impact of differentials attrition on the two indices. The Fields index is affected to a larger extent by differential attrition than the Shorrocks index, but the overall conclusions are not altered. Based on the Shorrocks (1978) index men across EU have an increasing mobility in the distribution of lifetime earnings as they advance in their career. Based on the Fields index (2008) the equalizing impact of mobility increases over the lifetime in all countries, except Portugal, where it turns negative for long horizons. Thus, Portugal is the only country where mobility acts as a disequalizer of lifetime differentials. The highest lifetime mobility is recorded in Denmark, followed by UK, and the lowest, Portugal. The highest mobility as equalizer of longer term inequality is recorded in Ireland and Denmark, followed by France and Belgium with similar values, then UK,

This question is answered by exploring short and long-term wage mobility for males across 14 EU countries between 1994 and 2001 using ECHP. Mobility is evaluated using rank measures which capture positional movements in the distribution of earnings. All countries recording an increase in cross-sectional inequality recorded also a decrease in short-term mobility. Among countries where inequality decreased, short-term mobility increased in Denmark, Spain, Ireland and UK, and decreased in Belgium, France and Ireland. Long-term mobility is higher than short-term mobility, but long-term persistency is still high in all countries. The lowest long-term mobility is found in Luxembourg followed by four clusters: first, Spain, France and Germany; second, Netherlands, and Portugal; third, UK, Italy and Austria; forth, Greece, Finland, Belgium and Ireland. The highest long-term mobi...

Earnings insecurity is proxied by transitory variability in earnings, which captures transitory earnings shocks, and by earnings volatility, which captures both permanent and transitory earnings shocks. Our results suggest that corporative bargaining systems, generous unemployment benefits, and deregulated product markets reduce the impact of macroeconomic shocks on transitory variability in earnings and earnings volatility, while a stronger labor protection legislation reduces the impact of macroeconomic shocks on earnings volatility. Several institutional mixes have the potential to reduce transitory variability, for example coupling a high corporatism with a high unionization, coupling protection mechanisms with activation policies, incorporating a trade-off between the generosity of unemployment benefits and the strictness of labor market regulation, and coupling product market deregulation with deregulated labor markets or with a high unionization. Two valuable lessons are that contextual interaction effects are important for understanding the influence of particular policies and institutions on earnings insecurity and that there is no one-size-fits all policy package for reducing the impact of the business cycle on transitory variability and volatility.

If earnings instability/volatility is a proxy for risk, for risk-averse individuals, increasing earnings instability/volatility bears substantial welfare costs. Using the European Community Household Panel and the OECD labour market indicators, we explore the cross-national di erences in earnings instability and earnings volatility across 14 European countries in the ...

The covariance structure of earnings is estimated using minimum distance methods. We ...
