This paper investigates the optimal income transfer problem at the low end of the income distribution. The government maximizes a social welfare function and faces the traditional equity-efficiency trade-off. The paper models labor supply behavioral responses along the intensive margin (hours or...

We revisit the role of temporary layoffs in the business cycle, motivated by their unprecedented surge during the pandemic recession. We first measure the contribution of temporary layoffs to unemployment dynamics over the period 1979 to the present. While many have emphasized a stabilizing...

This paper argues that a key aspect of the US labor market is the presence of time-varying heterogeneity across nonparticipants. We document a decline in the share of nonparticipants who report wanting to work, and we argue that that decline, which was particularly strong in the second half of...

We exploit a series of discontinuities, at several population thresholds, in the allocation mechanism of federal transfers to municipal governments in Brazil to identify the causal effect of municipal spending on local labor markets, using a ‘fuzzy' regression discontinuity design. Our...

Progressively targeted cash transfers remain the dominant policy response to chronic poverty in developing countries. But are there alternative social protection policies that might have larger poverty impacts over time for the same public expenditure? To explore this question, this paper...

Central to the welfare analysis of income transfer programs is the deadweight loss associated with possible reforms. To aid analytical tractability, its measurement typically requires specifying a simplified model of behavior. We employ a complementary “decomposition” approach that compares...

This paper shows that, contrary to commonly held views, the provisions of the social security law actually provide strong work incentives for older men. The reason is that, for most workers, higher current earnings lead to higher future social security benefits. These incentives have been...

Instrumental Variables (IV) methods identify internally valid causal effects for individuals whose treatment status is manipulable by the instrument at hand. Inference for other populations requires some sort of homogeneity assumption. This paper outlines a theoretical framework that nests all...

The purpose of the present note is to explore the structure of optimal income taxation/redistribution in an economy where the welfare of individuals depends in part on relative after-tax consumption, i.e., we specify individual welfare as a function of absolute and relative after-tax...
