The Distributional Effects of a Carbon Tax on Current and Future Generations
This paper examines the non-environmental welfare effects of introducing a revenue- neutral carbon tax policy. Using a life cycle model, we find that the welfare effects of the policy differ substantially for agents who are alive when the policy is enacted compared to those who are born into the new steady state with the carbon tax in place. Consistent with previous studies, we demonstrate that, for those born in the new steady state, the welfare costs are always lower when the carbon tax revenue is used to reduce an existing distortionary tax as opposed to being returned in the form of ...

A Wealth of Information: Augmenting the Survey of Consumer Finances to Characterize the Full U.S. Wealth Distribution
We use the Survey of Consumer Finances (SCF) to advance U.S. wealth analysis along several dimensions. We develop a comprehensive framework that modifies the SCF to recover the wealth distribution over families, tax units, and individuals from 1989 to 2019. We show that, by ignoring unequal holdings within families, existing estimates considerably understate U.S. inequality across individuals. We find wealth concentration rose through the recent economic recovery, which differs from leading models that capitalize income into wealth even after aligning conceptual differences. We illustrate ...

Unequal Climate Policy in an Unequal World
We study climate policy in an economy with heterogeneous households, two types of goods (clean and dirty), and a climate externality from the dirty good. Using household expenditure and emissions data, we document that low-income households have higher emissions per dollar spent than high-income households, making a carbon tax regressive. We build a model that captures this fact and study climate policies that are neutral with respect to the income distribution. A central feature of these policies is that resource transfers across consumers are ruled out. We show that the constrained optimal ...

On the optimal design of transfers and income-tax progressivity
We study the optimal design of means-tested transfers and progressive income taxes. In a simple analytical model, we demonstrate an optimally negative relation between transfers and income-tax progressivity due to efficiency and redistribution concerns. In a rich dynamic model, we quantify the optimal plan with flexible tax-and-transfer functions. Transfers should be larger than currently in the U.S. and financed with moderate income-tax progressivity. Transfers are key to implement higher progressivity in average than in marginal tax-and-transfer rates, achieving redistribution while ...

A Macroeconomic Model of Healthcare Saturation, Inequality and the Output-Pandemia Tradeoff
Covid-19 became a global health emergency when it threatened the catastrophic collapse of health systems as demand for health goods and services and their relative prices surged. Governments responded with lockdowns and increases in transfers. Empirical evidence shows that lockdowns and healthcare saturation contribute to explain the cross-country variation in GDP drops even after controlling for Covid-19 cases and mortality. We explain this output-pandemia tradeoff as resulting from a shock to subsistence health demand that is larger at higher capital utilization in a model with ...

Optimal Policy for Macro-Financial Stability
There is a new and now large literature analyzing government policies for financial stability based on models with endogenous borrowing constraints. These normative analyses build upon the concept of constrained efficient allocation, where the social planner is constrained by the same borrowing limit that agents face. In this paper, we show that the same set of policy tools that implement the constrained efficient allocation can be used by a Ramsey planner to replicate the unconstrained allocation, thus achieving higher welfare. The constrained social planner approach may lead to inaccurate ...

Preventing Controversial Catastrophes
In a market-based democracy, we model different constituencies that disagree regarding the likelihood of economic disasters. Costly public policy initiatives to reduce or eliminate disasters are assessed relative to private alternatives presented by financial markets. Demand for such public policies falls as much as 40% with disagreement, and crowding out by private insurance drives most of the reduction. As support for disaster-reducing policy jumps in periods of disasters, costly policies may be adopted only after disasters occur. In some scenarios constituencies may even demand policies ...

Migration, Congestion Externalities, and the Evaluation of Spatial Investments
The direct benefits of infrastructure in developing countries can be large, but if new infrastructure induces in-migration, congestion of other local publicly provided goods may offset the direct benefits. Using the example of rural household electrification in South Africa, we demonstrate the importance of accounting for migration when evaluating welfare gains of spatial programs. We also provide a practical approach to computing welfare gains that does not rely on land prices. We develop a location choice model that incorporates missing land markets and allows for congestion in local land. ...

Policy Externalities and Banking Integration
Can policies directed at the banking sector in one jurisdiction spill over and affect real economic activity elsewhere? To investigate this question, I exploit changes in tax rates on bank profits across U.S. states. Banks respond by reallocating small-business lending to otherwise unaffected states. Moreover, counties in non-tax-changing states that have more exposure to treated banks experience greater changes in lending, which in turn impacts local employment. The findings demonstrate that policies aimed at the banking sector in one jurisdiction can impose externalities on other regions. ...

These Caps Spilleth Over: Equilibrium Effects of Unemployment Insurance
The design of US unemployment insurance (UI) policy--which features benefits assigned as a percentage of past wages up to a cap--engenders tests for spillovers from policy variation to workers who are not directly treated. We test for and find a pattern of spillovers from state-level UI policy changes that cannot be neatly reconciled with workhorse or cutting-edge models of UI spillovers. Instead, we show that the documented pattern conforms with the predictions of a canonical model of information frictions: wage posting with random search. Taken together, our results provide novel evidence ...
