The Affordable Care Act introduces or expands taxes on incomes and full-time employment, beginning in 2014. The purpose of this paper is to characterize the new full-time employment taxes from the perspective of a household budget constraint, measure their magnitude, and assess their likely...

Using a quantitative model that features technical progress in automation and endogenous skill choice, we show that, given the current U.S. tax system, a sustained fall in automation costs can lead to a massive rise in income inequality. We characterize the optimal tax system in this model. We...

We address this question in a heterogeneous-agent incomplete-markets model featuring exogenous idiosyncratic risk, endogenous skill investment, and flexible labor supply. The tax and transfer schedule is restricted to be log-linear in income, a good description of the US system. Rising...

This paper concerns the problem of allocating a binary treatment among a target population based on observed covariates. The goal is to (i) maximize the mean social welfare arising from an eventual outcome distribution, when a budget constraint limits what fraction of the population can be...

This paper has two objectives. First, we identify a problem with the ability of the discrete-continuous choice (DCC) framework and conditional demand functions to fully describe consumer preferences in the presence of kinked budget constraints. Second, we propose and illustrate an alternative,...

In this paper we disentangle the sources of public sector inefficiency using 1982-1995 panel data on manufacturing firms in Indonesia. We consider two leading hypotheses: (1) public sector enterprises are inefficient due to monitoring problems and (2) public sector enterprises are inefficient...

Why do soft budget constraints exist and persist? In this paper we argue that the prevalence of soft budget constraints can be best explained by the political desirability of softness. We develop a political economy model where politicians cannot commit to policies that are not ex post optimal....

This paper studies consumption and labor supply in a model where agents have partial insurance and face risk and initial heterogeneity in wages and preferences. Equilibrium allocations and variances and covariances of wages, hours and consumption are solved for analytically. We prove that all...
