Standard theory of intertemporal choice predicts that people smooth out life-cycle changes in income by borrowing and saving, such that their standard of living in any given year depends more on lifetime income than on that year’s income. Yet, contemporary empirical studies of income...

Disability Insurance (DI) programs have long been criticized by economists for apparent work disincentives. Some countries have recently modified their programs such that DI recipients are allowed to keep some of their benefits if they return to work, and other countries are considering similar...

The interpretation of instrumental variables (IV) estimates as local average treatment effects (LATE) of instrument-induced shifts in treatment raises concerns about their external validity and policy relevance. We examine how to move beyond LATE in situations where the instrument is discrete,...

This paper uses a unique data set with nearly career-long earnings histories to provide evidence on the returns to schooling in current and lifetime earnings. We use these results to assess the importance of life-cycle bias in earnings regressions using current earnings as a proxy for lifetime...

Do market-orientated economies with relatively large cross-sectional levels of inequality have higher income mobility and therefore less permanent inequality? To answer this question, we introduce a formal representation of income mobility as an equalizer of permanent income. The proposed...

Strong intergenerational correlations in various types of welfare use have fueled a long-standing debate over whether welfare receipt in one generation causes welfare participation in the next generation. Some claim a causal relationship in welfare receipt across generations has created a...

When is one distribution (of income, consumption, or some other economic variable) more equal or better than another? This question has proven difficult to answer in situations where distribution functions intersect and no unambiguous ranking can be attained without introducing weaker criteria...

Why do individuals choose different types of post-secondary education, and what are the labor market consequences of those choices? We show that answering these questions is difficult because individuals choose between several unordered alternatives. Even with a valid instrument for every type...

This paper proposes a two-step aggregation method for measuring long-term income inequality and income mobility, where mobility is defined as an equalizer of long-term income. The first step consists of aggregating the income stream of each individual into a measure of permanent income, which...

This paper is concerned with the problem of ranking Lorenz curves in situations where the Lorenz curves intersect and no unambiguous ranking can be attained without introducing weaker ranking criteria than first-degree Lorenz dominance. To deal with such situations Aaberge (2009) introduced two...
