Title: Top Wealth in America: New Estimates Under Heterogeneous Returns
Abstract This article uses administrative tax data to estimate top wealth in the United States. We assemble new data that link people to their sources of capital income and develop new methods to estimate the degree of return heterogeneity within asset classes. Disaggregated fixed-income data reveal that rich individuals earn much more of their interest income in higher-yielding forms and have much greater exposure to credit risk. Consequently, in recent years, the interest rate on fixed income at the top is approximately 3.5 times higher than the average. We value the population of U.S. firms using firm-level characteristics and apportion this wealth using firm-owner links. We combine this new data on fixed income and pass-through business returns with refined estimates of C-corporation equity, housing, and pension wealth to deliver new capitalized wealth estimates that build upon the methods of Saez and Zucman (2016a). From 1989 to 2016, the top 1%, 0.1%, and 0.01% wealth shares increased by 6.6, 4.6, and 2.9 percentage points, respectively, to 33.7%, 15.7%, and 7.1%. Overall, although we estimate a large degree of return heterogeneity, accounting for this heterogeneity does not change the fundamental story for top wealth shares and their growth—wealth inequality is high and has risen substantially over recent decades.  more » « less

    We study the effect of interest rates on wealth inequality. While lower rates decrease the growth rate of rentiers, they also increase the growth rate of entrepreneurs by making it cheaper to raise capital. To understand which effect dominates, we derive a sufficient statistic for the effect of interest rates on the Pareto exponent of the wealth distribution: it depends on the lifetime equity and debt issuance rate of individuals in the right tail of the wealth distribution. We estimate this sufficient statistic using new data on the trajectory of top fortunes in the U.S. Overall, we find that the secular decline in interest rates (or more generally of required rates of returns) can account for about 40% of the rise in Pareto inequality; that is, the degree to which the super rich pulled ahead relative to the rich.

    Many studies use matched employer-employee data to estimate a statistical model of earnings determination with worker and firm fixed effects. Estimates based on this model have produced influential yet controversial conclusions. The objective of this paper is to assess the sensitivity of these conclusions to the biases that arise because of limited mobility of workers across firms. We use employer-employee data from the US and several European countries while taking advantage of both fixed-effects and random-effects methods for bias-correction. We find that limited mobility bias is severe and that bias-correction is important.

    This paper argues that high marginal labor income tax rates on top earners are an effective tool for social insurance even when households have high labor supply elasticity, households make dynamic savings decisions, and policies have general equilibrium effects. We construct a large-scale overlapping generations model with uninsurable labor productivity risk, show that it has a realistic wealth distribution, and numerically characterize the optimal top marginal rate. We find that marginal tax rates for top 1 percent earners of 79 percent are optimal as long as the model earnings and wealth distributions display a degree of concentration as observed in US data.

    ABSTRACT Historical inequality is difficult to measure, especially at the subcountry level and beyond the top income shares. This article presents new evidence on the level of inequality in Manhattan from 1880 to 1910 using housing rents. Rental prices and characteristics, including geocodable locations, were collected from newspapers and provide extensive geographic coverage of the island, relevant for the overwhelming majority of its population where renting predominated. This provides a measure of consumption inequality at the household level, which helps to develop the picture of urban inequality for this period, when income and wealth measures are scarce. For large American cities, but particularly for New York, housing made up a large share of consumption expenditure and its consumption cannot be substituted, so this is a reliable and feasible way to identify the true trends in urban inequality across space and time.

    In this paper, we study household consumption-saving and portfolio choices in a heterogeneousagent economy with sticky prices and time-varying total factor productivity and idiosyncratic stochastic volatility. Agents can save through liquid bonds and illiquid capital and shares. With rich heterogeneity at the household level, we are able to quantify the impact of uncertainty across the income and wealth distribution. Our results help us in identifying who wins and who loses when during periods of heightened individual and aggregate uncertainty. To study the importance of heterogeneity in understanding the transmission of economic shocks, we use a deep learning algorithm. Our method preserves non-linearities, which is essential for understanding the pricing decisions for illiquid assets.
