We study the history and geography of wealth accumulation in the United States using newly collected historical property tax records from the early 1800s onward. These records come from the administration of the General Property Tax–a tax that aspired to cover all types of property. We construct wealth series at the state, county, and national levels. At the state level, we use annual assessed values of wealth from state-level reports drawn from multiple sources. Because assessed values may differ from market values, we also require assessment ratios, defined as the ratio of assessed to market wealth. We obtain state-level assessment ratios from decadal U.S. Census wealth data (drawn from various Census reports, including those on “Wealth, Debt, and Taxation”), in which the Census carried out detailed valuation work, complemented with information on changes in assessment practices from the state reports, to build higher-frequency series of assessment ratios. The result is long-run annual wealth series for states from 1850 (or earlier, depending on the state) to 1935. We obtain national wealth series by aggregating these state series. At the county level, we use assessed values (or market values where available) from the U.S. Census wealth data for each decade, and apply either state-level or county-level assessment ratios, where available, to obtain market values of wealth for each decade from 1850 to 1930. We use these data to show, first, that the United States experienced extraordinary wealth accumulation after the Civil War and until the Great Depression. Second, spatial inequality in the United States has been large and highly persistent since the mid-1800s. We also examine the determinants of long-term wealth growth and find, among other results, that counties with a higher share of enslaved property before the Civil War or with higher wealth inequality experienced lower subsequent long-run wealth growth.

This paper builds a world atlas of child penalties in employment based on microdata from 134 countries. The estimation of child penalties is based on pseudo-event studies of first child birth using cross-sectional data. The pseudo-event studies are validated against true event studies using panel data for a subset of countries. Most countries display clear and sizable child penalties: men and women follow parallel trends before parenthood, but diverge sharply and persistently after parenthood. While this pattern is pervasive, there is enormous variation in the magnitude of the effects across different regions of the world. The fraction of gender inequality explained by child penalties varies systematically with economic development and proxies for structural transformation. At low levels of development, child penalties represent a minuscule fraction of gender inequality. But as economies develop—incomes rise and the labour market transitions from subsistence agriculture to salaried work in industry and services—child penalties take over as the dominant driver of gender inequality. The relationship between child penalties and development is validated using historical data from current high-income countries, back to the 1700s for some countries. Finally, because parenthood is often tied to marriage, we also investigate the existence of marriage penalties in female employment. In general, women experience both marriage and child penalties, but their relative importance depends on the level of development. The development process is associated with a substitution from marriage penalties to child penalties, with the former gradually converging to zero.

Short-time work (STW) policies provide subsidies for hour reductions to workers in firms experiencing temporary shocks. They are the main policy tool used to support labour hoarding during downturns and were aggressively used during the coronavirus disease 2019 (COVID-19) pandemic. Yet, very little is known about their employment and welfare consequences. This article leverages unique administrative social security data from Italy and quasi-experimental variation in STW policy rules to offer evidence on the effects of STW on firms’ and workers’ outcomes during the Great Recession. Our results show large and significant negative effects of STW treatment on hours, but large and positive effects on headcount employment. We then analyse whether these positive employment effects are welfare enhancing, distinguishing between temporary and more persistent shocks. We first provide evidence that liquidity constraints and rigidities in wages and hours may make labour hoarding inefficiently low without STW. Then, we show that adverse selection of low productivity firms into STW reduces the long-run insurance value of the program and creates significant negative reallocation effects when the shock is persistent.

Due to the absence of unemployment insurance (UI) choices, the traditional approach to estimating the value of UI is to infer it from the observed consumption response to job loss under some assumption on risk preferences. Exploiting the rich data and unique policy context in Sweden, we propose two alternative approaches that relax this assumption and we implement all three methods on the same sample of workers. The first approach considers the difference in marginal propensity to consume (MPC) when unemployed versus employed, which allows to identify the difference in prices to smooth consumption in the respective states. The second approach exploits UI choices embedded in the Swedish UI system in a Revealed Preference approach. While the drop in consumption expenditures is relatively small (∼13%), we find that the MPC is around 25% higher when unemployed than employed, translating into a marginal value of transfers that is at least 60% higher when unemployed than employed. This high value of UI is confirmed by our RP estimates and indicates substantial risk aversion given the relatively small drop in consumption expenditures.

We analyze the effects of top tax rates on international migration of football players in 14 European countries since 1985. Both country case studies and multinomial regressions show evidence of strong mobility responses to tax rates, with an elasticity of the number of foreign (domestic) players to the net-of-tax rate around one (around 0.15). We also find evidence of sorting effects (low taxes attract highability players who displace low-ability players) and displacement effects (low taxes on foreigners displace domestic players). Those results can be rationalized in a simple model of migration and taxation with rigid labor demand.

This article analyzes the effects of income taxation on the international migration and earnings of top earners using a Danish preferential foreigner tax scheme and population-wide Danish administrative data. This scheme, introduced in 1991, allows new immigrants with high earnings to be taxed at a preferential flat rate for a duration of three years. We obtain two main results. First, the scheme has doubled the number of highly paid foreigners in Denmark relative to slightly less paid—and therefore ineligible—foreigners. This translates into a very large elasticity of migration with respect to 1 minus the average tax rate on foreigners, between 1.5 and 2. Second, we find compelling evidence of a negative effect of the scheme-induced reduction in the average tax rate on pretax earnings of foreign migrants at the individual level. This finding can be rationalized by a matching frictions model with wage bargaining where there is a gap between pay and marginal productivity.

We provide evidence that unemployment insurance affects equilibrium conditions in the labor market, which creates significant “market externalities.” We provide a framework for identification of such equilibrium effects and implement it using the Regional Extension Benefit Program (REBP) in Austria which extended the duration of UI benefits for a large group of eligible workers in selected regions of Austria. We show that non-eligible workers in REBP regions have higher job finding rates, lower unemployment durations, and a lower risk of long-term unemployment. We discuss the implications of our results for optimal UI policy.

Using administrative data from Scandinavian countries, we provide evidence on international migration responses to wealth taxes and evaluate their aggregate economic implications. We find significant migration responses among the wealthy: A 1 percentage point increase in the top wealth tax rate decreases the stock of wealthy taxpayers by about 2 percent. A large fraction of the wealthy are business owners, and their businesses are negatively affected by owner out-migration. The aggregate effects are nevertheless modest: The migration responses to a 1 percentage point increase in the top wealth tax rate reduce employment by 0.02 percent, investments by 0.07 percent, and value added by 0.10 percent.

This paper studies whether adverse selection can rationalize a universal mandate for unemployment insurance (UI). Building on a unique feature of the unemployment policy in Sweden, where workers can opt for supplemental UI coverage above a minimum mandate, we provide the first direct evidence for adverse selection in UI and derive its implications for UI design. We find that the unemployment risk is more than twice as high for workers who buy supplemental coverage. Exploiting variation in risk and prices, we show how 25–30 percent of this correlation is driven by risk-based selection, with the remainder driven by moral hazard. Due to the moral hazard and despite the adverse selection we find that mandating the supplemental coverage to individuals with low willingness-to-pay would be suboptimal. We show under which conditions a design leaving choice to workers would dominate a UI system with a single mandate. In this design, using a subsidy for supplemental coverage is optimal and complementary to the use of a minimum mandate.

This paper analyzes consumption to evaluate the distributional effects of pension reforms. Using Swedish administrative data, we show that on average, workers who retire earlier consume less while retired and experience larger drops in consumption around retirement. Interpreted via a theoretical model, these findings imply that reforms incentivizing later retirement incur a substantial consumption smoothing cost. Turning to other features of pension policy, we find that reforms that redistribute based on early-career labor supply would have opposite-signed redistributive effects, while differentiating on wealth may help to target pension benefits toward those who are vulnerable to larger drops in consumption around retirement.
