Has the U.S. Distribution of Wealth Worsened?

Wealth inequality in the United States is obvious to everyone. The Federal Reserve’s triennial Survey of Consumer Finance (SCF) documents the glaring and persistent divide between rich and poor, confirming that ownership of financial and real assets in the United States has been highly concentrated for decades (see our earlier post). The most recent 2016 estimates suggest that the top 10% of the wealth distribution own nearly three-quarters of all marketable assets, with the top 1% owning more than half of that. And, Saez and Zucman (SZ) estimate that the U.S. distribution has been getting worse, with the top 1% share of marketable wealth rising by more than 10 full percentage points since 1989.

But, as Catherine, Miller and Sarin (CMS) recently highlight, adding in the present discounted value of Social Security benefits (net of taxes) to construct a more comprehensive measure of wealth alters these patterns. First, according to CMS’s estimates, the share of marketable wealth in total wealth has plunged by more than 18 percentage points since 1989. Second, over the past three decades, the top 1% share of total wealth has risen only modestly, while the share owned by the top 10% has declined somewhat.

In this post, we highlight the CMS results, and decompose their changes in total wealth shares into two parts: the changes in marketable and Social Security wealth shares accruing to each group, and the aggregate decline over time of marketable wealth as a share of total wealth. We show that the latter dominates the overall trend in this more comprehensive measure of inequality….

Fiscal Sustainability: A Primer

Nobody likes taxes, so public spending frequently exceeds revenues, leading governments to borrow. These budget deficits are a flow that add to the stock of debt. Since the Great Financial Crisis of 2007-2009, public debt in a number of advanced economies has surged. In the United States. the Congressional Budget Office (CBO) recently projected that―in the absence of policy changes―federal debt held by the public is headed for record highs (as a ratio to GDP) in coming decades.

Importantly, there is a real (inflation-adjusted) limit to how much public debt a government can issue (see Sargent and Wallace). Beyond that limit, the consequences are outright default or, if the debt is in domestic currency bonds that the central bank acquires, inflation that erodes its real value leading to a partial default.

Ultimately, debt sustainability requires that a country’s ratio of public debt to GDP stabilize. Otherwise, debt eventually will rise above the real limit and trigger default or inflation. In this note, we derive and interpret a simple debt-sustainability condition. The condition states that the government primary surplus―the excess of government revenues over noninterest spending—must be at least as large as the stock of outstanding sovereign debt times the difference between the nominal interest rate the government has to pay and the rate of growth of nominal GDP. If it is not, then the ratio of debt to GDP will explode….

On the Distribution of Wealth

In an effort to understand the dynamics of the distribution of consumption, income and wealth, over the past decade, there has been an explosion of research. While important debates about measurement and data interpretation continue, a range of evidence points to two important conclusions. First, over the past two centuries, the global income distribution has become far more equal. But, while the gap between countries is now much smaller, in recent decades, inequality within some advanced countries, especially in the United States, has risen.

Rather than income or consumption, in this post we focus on the distribution of wealth. Wealth affects welfare in at least two key ways. First, in the presence of borrowing constraints, it provides a buffer against fluctuations of income, allowing households to smooth consumption in the face of temporary bouts of illness or unemployment. Second, it provides the basis for household spending in retirement. .

As we will see, the distribution of wealth is far less equal than that of income. Moreover, recent research shows that, following the Great Financial Crisis of 2007-2009, the U.S. wealth distribution has become decidedly more unequal. As a result, a large portion of U.S. households appears to have little scope for meeting retirement needs out of their current net worth, making federal insurance programs key to their future well-being.

Improving U.S. Healthcare and Coverage

We see health as a basic human right. Every society should provide medical care for its citizens at the level it can afford. And, while the United States has made some progress in improving access to care, the results do not justify the costs. So, while we agree with President Trump’s statement that the U.S. health care system should be cheaper, better and universal, the question is how to get there.

In this post, we start by setting the stage: where matters stand today and why they are unacceptable. This leads us to the real question: where can and should we go? As economists, we are genuinely partial to market-based solutions that allow individuals to make tradeoffs between quality and price, while competition pushes suppliers to contain costs. But, in the case of health care, we are skeptical that such a solution can be made workable. This leads us to propose a gradual lowering of the age at which people become eligible for Medicare, while promoting supplier competition....
