We use micro data from the U.S. Internal Revenue Service to document how households' tax liabilities vary with income, marital status and the number of dependents. We report facts on the distributions of average and marginal taxes, properties of the joint distributions of taxes paid and income,...

We develop a span-of-control model where managerial skills are endogenous and the outcome of investments over the life cycle of managers. We calibrate this model to U.S plant-size data to quantify the effects of distortions that are correlated with the size of production units. These distortions...

Based on well-known evidence on labor supply elasticities, several authors have concluded that women should be taxed at lower rates than men. We evaluate the quantitative implications of taxing women at a lower rate than men. Relative to the current system of taxation, setting a proportional tax...

We document that for a group of high-income countries (i) mean earnings of managers tend to grow faster than for non managers over the life cycle; (ii) the earnings growth of managers relative to non managers over the life cycle is positively correlated with output per worker. We interpret this...

We evaluate the effectiveness of a more progressive tax scheme in raising government revenues. We develop a life-cycle economy with heterogeneity and endogenous labor supply. Households face a progressive income tax schedule, mimicking the Federal Income tax, and flat-rate taxes that capture...

What would be the aggregate effects of adopting a more generous and universal childcare subsidy program in the U.S.? We answer this question in a life-cycle equilibrium model with joint labor-supply decisions of married households along extensive and intensive margins, heterogeneity in terms of...
