An Update on Wealth Mobility
We measure wealth mobility in the United States. Using the latest wave of the Panel Study of Income Dynamics (PSID), we update Carroll and Hoffman (2017), who document a decreasing trend in wealth mobility over the past 30 years. We confirm another of their findings that large upward movements in wealth are associated with families’ owning businesses and real estate other than a primary residence. Finally, we turn to the much larger Survey of Income and Program Participation (SIPP) data and document that these “large mover” households are evident even over three-year periods.

Mobility
This paper studies short-run wealth mobility in a heterogeneous agents, incomplete-markets model. Wealth mobility has a ?hump-shaped? relationship with the persistence of the stochastic process governing labor income: low when shocks are close to i.i.d. or close to a random walk, and higher in between. The standard incomplete markets framework features less wealth mobility than found in the PSID wealth supplements. We include features commonly used in the literature to capture wealth inequality and find that they do little to improve the model?s performance for wealth mobility. Finally, we ...

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 ...

Reducing the federal deficit: approaches in some other countries
The United States is not the first advanced modern economy to face a serious federal budget challenge. A number of countries have seen their debt rise to unacceptable levels in recent decades, and they have taken steps to rein it in. We explore the approaches that Canada and the United Kingdom have used. Though there are important differences in approaches and countries, we draw five useful lessons for the reforms that may be proposed in the U.S. as it addresses its fiscal challenges.

Why Are Headline PCE and Median PCE Inflations So Far Apart?
Mean (or headline) PCE inflation has typically fallen below median PCE inflation, and since 2012 the difference has been large. To understand the reasons for this trend, we investigate which components of the headline measure are contributing to the difference. We find that energy components, which frequently undergo wide price swings, and electronics, which have been steadily decreasing in price for decades, explain most of the difference between the two inflation measures. We argue that the outsized impacts of such components on headline PCE inflation reinforce the need for policymakers to ...

A note on sunspots with heterogeneous agents
This paper studies sunspot fluctuations in a model with heterogeneous households. We find that wealth inequality reduces the degree of increasing returns needed to produce indeterminacy, while wage inequality increases it. When the model is calibrated to match the joint distribution of hours, income, and wealth, the required degree of increasing returns to scale is still much too high to be supported empirically (although smaller than similar homogeneous agent economies). We also find that the model robustly predicts only one sunspot, despite having 1,262 predetermined state variables.

The Racial Wealth Gap and Access to Opportunity Neighborhoods
Some Black households live in neighborhoods with lower incomes, as well as higher unemployment rates and lower educational attainment, than their own incomes might suggest, and this may impede their economic mobility. We investigate reasons for the neighborhood sorting patterns we observe and find that differences in financial factors such as income, wealth, or housing costs between Black and white households do not explain racial distributions across neighborhoods. Our findings suggest other factors are at work, including discrimination in the housing market, ongoing racial hostility, or ...

Can Wealth Explain Neighborhood Sorting by Race and Income?
Why do high-income blacks live in neighborhoods with characteristics similar to those of low-income whites? One plausible explanation is wealth, since homeownership requires some wealth, and black households hold less wealth than white households at all levels of income. We present evidence against this hypothesis by showing that wealth does not predict sorting into neighborhood quality once race and income are taken into account. An alternative explanation is that the scarcity of high-quality black neighborhoods increases the cost of living in a high-quality neighborhood for black households ...
Working Paper
The Politics of Flat Taxes
We study the determination of flat tax systems using a workhorse macroeconomic model of inequality. Our first result is that, despite the multidimensional policy space, equilibrium policies are typically unique (up to a fine grid numerical approximation). The majority voting outcome features (i) zero labor income taxation, (ii) simultaneous use of capital income and consumption taxation, and (iii) generally low transfers. We discuss the role of three factors?the initial heterogeneity in sources of income, the mobility of income and wealth, and the forward-looking aspect of voting?in ...

On the Distributional Effects of International Tariffs
We provide a quantitative analysis of the distributional effects of the 2018 increase in tariffs by the US and its major trading partners. We build a trade model with incomplete asset markets and households that are heterogeneous in their age, income, wealth, and labor skill. When tariff revenues are used to reduce distortionary taxes on consumption, labor, and capital income, the average welfare loss from the trade war is equivalent to a permanent 0.1 percent reduction in consumption. Much larger welfare losses are concentrated among retirees and low-wealth households, while only wealthy ...
