We study food Engel curves among the poor population targeted by a conditional cash transfer programme in Colombia. After controlling for the endogeneity of total expenditure and for the (unobserved) variability of prices across villages, the best fit is provided by a log-linear specification....

The paper develops a new approach to measuring the impact of government cash transfers on poverty alleviation that takes into account endogenous reactions and consumption smoothing of households. We use the methodology to study the impact of changes in government cash benefits on poverty rates...

This paper studies the effect of top tax rates on inventors' mobility since 1977. We put special emphasis on "superstar" inventors, those with the most and most valuable patents. We use panel data on inventors from the United States and European Patent Offices to track inventors' locations over...

Private pension provision faces the challenging task of providing stable income streams during retirement. The challenge has increased markedly in the last decades due to volatile financial markets, falling interest rates and the withdrawal of employers and external insurers as risk bearers of...

We study the incentives of parents to invest in their children when these investments improve their marriage prospects, in a frictionless marriage market with non-transferable utility. Stochastic returns to investment eliminate the multiplicity of equilibria that plagues models with...

A wide body of empirical evidence, based on randomized experiments, finds that 20-40 percent of fiscal stimulus payments (e.g. tax rebates) are spent on non-durable household consumption in the quarter that they are received. We develop a structural economic model to interpret this evidence. Our...

Can public insurance through redistributive income taxation improve the allocation of risk in an economy in which private risk sharing is limited? The answer depends crucially on the fundamental friction that limits private risk sharing in the first place. If risk sharing is incomplete because...

Political survey data for nine West European countries show that women have become increasingly left-wing compared to men, and that this trend is positively correlated with the decline in marriage in these countries. This pattern is mirrored in German longitudinal data (GSOEP), where transitions...

This paper decomposes the sources of risk to income that individuals face over their lifetimes. We distinguish productivity risk from employment risk and identify the components of each using the Survey of Income and Program Participation and the Panel Study of Income Dynamics. Estimates of...

In terms of the ratio of its public debt and public deficit to GDP the United States lies in the middle of the pack of industrial countries. The period since 1980 is the only peacetime period outside the Great Depression to see a sustained increase in the debt-GDP ratio. The budgetary...
