Working Paper
Wealth inequality: data and models

In the United States wealth is highly concentrated and very unequally distributed: the richest 1% hold one third of the total wealth in the economy. Understanding the determinants of wealth inequality is a challenge for many economic models. We summarize some key facts about the wealth distribution and what economic models have been able to explain so far.

Working Paper
Taxation, entrepreneurship, and wealth

Entrepreneurship is a key determinant of investment, saving, and wealth inequality. We study the aggregate and distributional effects of several tax reforms in a model that recognizes this key role and that matches the large wealth inequality observed in the U.S. data. The aggregate effects of tax reforms can be particularly large when they affect small and medium-sized businesses, which face the most severe financial constraints, rather than big businesses. The consequences of changes in the estate tax depend heavily on the size of its exemption level. The current effective estate tax system ...

Inequality and Recessions

The increase in inequality over the past several decades has received widespread attention from both academics and the public at large. While much of this discourse centers on either the causes or normative implications of increasing inequality, it is important to ask whether the widening gap between the rich and poor has any direct effects on macroeconomic aggregates and, in particular, on the severity of the Great Recession, when output and consumption dropped precipitously and were slow to recover (see figure 1).

Working Paper
Wealth inequality, intergenerational links and estate taxation

Empirical studies have shown that, for many countries, the distribution of wealth is much more concentrated than the one of labor earnings. We do not have yet a satisfactory model that can generate enough concentration in wealth from the one for earnings. I construct a computable general equilibrium model with overlapping generations in which parents and children are linked by bequests and earnings within families. I show that bequests are important to explain the emergence of large estates that characterize the top of the wealth distribution and that the introduction of a bequest motive ...

Working Paper
Life expectancy and old age savings

Rich people, women, and healthy people live longer. We document that this heterogeneity in life expectancy is large. We use an estimated structural model to assess the impact of life expectancy variation on the elderly?s savings. We find that the differences in life expectancy related to observable factors such as health, gender, and income have large effects on savings, and that these factors contribute by similar amounts. We also show that the risk of outliving one?s expected lifespan has a large effect on the elderly?s saving behavior.

Working Paper
Wage Risk and Government and Spousal Insurance

The extent to which households can self-insure and the government can help them to do so depends on the wage risk that they face and their family structure. We study wage risk in the UK and show that the persistence and riskiness of wages depends on one's age and position in the wage distribution. We also calibrate a model of couples and singles with two alternative processes for wages: a canonical one and a flexible one that allows for the much richer dynamics that we document in the data. We use our model to show that allowing for rich wage dynamics is important to properly evaluate the ...

Female Labor Supply and Why Women Need to Be Included in Economic Models

Women contribute a large fraction of aggregate labor hours, earnings, and labor force participation. Yet, many models used to study the effects of government policy ignore gender differences and use data on men only. These models are used extensively for examining the effects of government policies and programs?including Social Security, taxation, and welfare programs. Before evaluating how people respond to such policies, it is important to construct a reliable model of how people behave and why.

Savings after Retirement: A Survey

Retired U.S. households, especially those with high income, decumulate their assets more slowly than implied by the basic life cycle model. The observed patterns of out-of-pocket medical expenses, which rise quickly with age and income during retirement, and longevity, which also rises with income, can explain a significant portion of U.S. retirement saving. However, more work is needed to disentangle these precautionary motives from other motives, such as the desire to leave bequests.

Rescuing asset-backed securities markets

On November 25, 2008, the Federal Reserve unveiled a loan facility to revive the market for asset-backed securities, which had essentially stopped functioning due to the global financial crisis. What are these securities and why is it important for these markets to continue to operate?
