How the New Model of Marriage May Drive Income Inequality

Our last two podcasts, “Why Marry?” (Part 1 and Part 2) explored the broad and deep changes in the institution of marriage. One theme was that the old marriage model of “production complementaries” has shifted to one based on “consumption complementarities.” Here’s Justin Wolfers on the subject:

We have more time, more money, and so you want to spend it with someone that you’ll enjoy. So, similar interests and passions. We call this the model of hedonic marriage. But really it’s a lot more familiar than that. This is just economists giving a jargon name to love. So you want someone who’s actually remarkably similar to you or has similar passions that you do. So it fundamentally changes who marries who.

But is this change also related to income inequality? Wolfers briefly referenced that idea a few years back; in a recent article for Vox, the economics Jeremy Greenwood, Nezih Guner, Georgi Kocharkov, and Cezar Santos further the argument:


The Gini Coefficient

A recent issue of the Handelsblatt (the German Wall Street Journal equivalent) had a neat graphic comparison of the U.S. to 5 other major countries: France, Germany, Italy, Spain and the U.K., along the criteria of the Gini coefficients on pre-tax/transfer incomes, post-tax/transfer incomes, and household wealth. Our pre-Gini on incomes is slightly below that in Italy, a bit higher than in the other four countries.  The big difference is that our post-Gini is much higher than in all the other countries—0.38 compared to a range of 0.29 to 0.34.  We do much less redistribution through transfers and have flatter taxes.

It is thus not surprising that we win the Champions League of Gini wealth inequality:  Ours is 0.85, with a range of 0.65 to 0.78 in the other five countries. The tiny tax increase on the top 1 percent of households that took so much political energy last year will do almost nothing to strip us of our championship status.


What Is the Relationship Between Income Inequality and Revolution?

A pair of interesting-looking papers, particularly interesting when paired, about income inequality and its relationship (or not?) to revolutions. From “Russian Inequality on the Eve of Revolution,” by Steven Nafziger and Peter H. Lindert:

Just how unequal were the incomes of different classes of Russians on
the eve of Revolution, relative to other countries, to Russia’s earlier history, and to Russia’s income distribution today? Careful weighing of an eclectic data set provides provisional answers.    We provide detailed income estimates for economic and social classes in each of the 50 provinces of European Russia.  In 1904, on the eve of military defeat and the 1905 Revolution, Russian income inequality was middling by the standards of that era, and less severe than inequality has become today in such countries as China, the United States, and Russia itself.  We also note how the interplay of some distinctive fiscal and relative-price features of Imperial Russia might have shaped the now-revealed level of inequality.


Is Income Inequality Rising, and Are a Lot of Feathers Heavy?

New data on income inequality in the United States were just released.  And they provide a useful teaching moment. The graph below, which comes from the Census Bureau, shows the evolution of the Gini coefficient since 1967.  It’s pretty clear that this measure of inequality has been rising pretty much through this whole period.

p>But here’s how the Census Bureau chose to describe these data:

Based on the Gini index, income inequality increased by 1.6 percent between 2010 and 2011; this represents the first time the Gini index has shown an annual increase since 1993, the earliest year available for comparable measures of income inequality.

Say what?


Inequality Across U.S. States

A Bloomberg article by Virginia Postrel explores a discouraging trend in income inequality.  For decades, incomes across states in the U.S. converged — i.e. poor states caught up to rich ones — just as Robert Solow‘s growth theory predicted:

Poor places are short on the capital that would make local labor more productive. Investors move capital to those poor places, hoping to capture some of the increased productivity as higher returns. Productivity gradually equalizes across the country, and wages follow. When capital can move freely, the poorer a place is to start with, the faster it grows.

That steady convergence, however, has stopped.  One possible explanation?  High housing prices in rich cities, caused by government regulation:


Tax Deductions or Tax Expenditures?

Chances are, you’re going to spend tonight finalizing your taxes, making sure that you ferret every last deduction. And probably pretty pleased to be getting these deductions; but when you dig in a bit deeper, you may not be so sure — at least that’s what Betsey Stevenson and I argue in our latest column.

In fact, tax breaks are no different from either government handouts, or federal mandates, whether evaluated in terms of your finances, the government’s finances, or incentives:

Instead of looking at all the breaks for mortgage interest, health care, retirement savings and so on as deductions, picture the government writing you a check for each item. This equivalence between tax deductions and government spending leads economists to call them “tax expenditures.” Reformers have hit on an even more pointed description: spending through the tax code.


Is Higher Income Inequality Associated with Lower Intergenerational Mobility?

A lot of our political debate boils down to questions about equality of outcomes versus equality of opportunity. But it turns out that they’re pretty closely related. Take a look at the chart below, which is from a terrific recent speech (with charts!) by Alan Krueger:

The horizontal axis shows the Gini coefficient, which is a summary of the degree of income inequality for each country. I think of this as a measure of inequality of outcomes. The United States sits out there on the right, which says that we have high inequality, which I bet that doesn’t surprise you.


Of Lags and Caps: Possible Implementations of a Brandeis Tax

Last Monday, Aaron Edlin and I published a cri de coeur op-ed in the New York Times calling for a Brandeis tax, an automatic tax that would put the brakes on income inequality. This is the third in a series of posts (the first and second posts are here and here) explaining more about our rationale and providing more details on how a Brandeis tax might be implemented. You can also listen to my hour-long interview on Connecticut Public Radio’s “Where we Live” here.

Of Lags and Caps: More Details About Possible Implementations of a Brandeis Tax
By Ian Ayres & Aaron Edlin

Remarkably of the hundreds of emails we received in reaction to our op-ed, almost no one questioned Brandeis’s idea that we can have great concentrations of wealth, or democracy but not both. People questioned other aspects of our proposal, asking questions like (1) how would it work in a world of income bunching; (2) would people still have the incentive to work hard; and (2) is it fair to have very high tax rates on the affluent.

Our last post talked about alternative potential triggers. Here we tackle some more detailed questions about implementation including how to trade off different kinds of distortions.


An Inequality Tax Trigger: The Brandeis Ratio Explained

On Monday, Aaron Edlin and I published a cri de coeur op-ed in the New York Times calling for a Brandeis tax, an automatic tax that would put the brakes on income inequality. This is the second in a series of posts (the first post is here) explaining more about our rationale and providing more details on how a Brandeis tax might be implemented.

An Inequality Tax Trigger
By Ian Ayres and Aaron Edlin

A central idea behind our Brandeis tax proposal was to have a tax that is triggered by increases in inequality. Our Brandeis tax does not target excessive income per se; it only caps inequality. Billionaires could double their current income without the tax kicking in — as long as the median income also doubles. The sky is the limit for the rich as long as the “rising tide lifts all boats.” Indeed, the tax gives job creators an extra reason to make sure that corporate wealth does in fact trickle down.


There Will Be Rich Always: Finding a New Way to Think About Income Inequality

On Monday, Aaron Edlin and I published a cri de coeur op-ed in the New York Times calling for a Brandeis tax, an automatic tax that would put the brakes on income inequality. In the next few days, Aaron and I will be publishing a series of posts explaining more about our rationale and providing more details on how a Brandeis tax might be implemented.

There Will Be Rich Always
By Ian Ayres & Aaron Edlin

In one of the more memorable lyrics from the musical Jesus Christ Superstar (based on Matthew 26:11), Jesus tells his disciples “There will be poor always.”

The same is true of the rich. There will always be a top 1 percent of income earners. But what it takes to be rich can change drastically over the course of even a single generation. In 1980, you would have had to earn at least $158,000 to be a one-percenter; but by 2006 the qualifying amount had more than doubled to $332,000. (You can produce an estimate of your own household income percentile – albeit using a different definition of income that produces a much higher 1 percent cutoff – at this wsj.com site.) The rise is not due to inflation as both these numbers are expressed in inflation-adjusted, constant 2006 dollars.


Daron Acemoglu on Inequality

If you’re even a little bit interested in income inequality and how it matters, this Browser interview with MIT economist Daron Acemoglu is a must-read. Acemoglu explains how economists generally think about inequality:

The default position of economists is that inequality reflects the unequal human capital or productive capabilities of different workers. If you start with that premise – that what people earn is commensurate with their contribution to their employer, and also perhaps to society – then greater inequality tells you something about how people’s productivities have evolved over time. This is by no means what every economist believes, but it’s a common view. Economists have cut their teeth on inequality by looking at things like the increase in the college premium over the last 30 years in the U.S. and other economies, as well as the increase in the gap between relatively high earners – the 90th percentile of income distribution – versus the bottom 10th percentile. We’ve seen a big increase in inequality, measured in various ways, and this reflects the fact that the top people, the more educated, high earners have become more skilled. Technology has favored them, globalization has favored them, and inequality has increased for that reason.


College and the Widening Wealth Gap

If a picture is worth a thousand words, then a few Economic Policy Institute snapshots might be the Great Novel of our time. A few weeks ago, Heidi Shierholz at EPI brought us yet another harrowing tale from the front lines of the recession generation. In an “Economic Snapshot,” she writes:

As college students head back to the classroom this semester, a harsh reality confronts them — the rewards for the time, energy, and money that young people put into college are less than they were a decade ago. Since 2000, America’s young college graduates have seen wages, adjusted for inflation, deteriorate. This lack of wage growth may be particularly surprising to those used to reading about the vast unfilled need for college graduates, which if true would lead to increases in their earnings.

But how is this happening? Maybe it has something to do with a more recent snapshot from Lawrence Mishel at EPI on the growing wealth gap in America. He writes:


Did Women's Lib Movement Increase Income Gap in the U.S.?

Reader Chris Fawcett writes in with an intriguing question: How did the women’s liberation movement affect the income gap in the U.S.?
Income inequality has been on the rise in the U.S. since the 1970s, roughly the same time that women began entering the workforce in large numbers. Considering the amount of attention the widening income gap gets these days as a source of our economic woes, it seemed like something worth posting.
Here’s how Chris sees the issue:

There are a number of ways I believe this has had a big impact (maybe the biggest impact of any single issue):
1. Women’s participation in the workplace has doubled in the past half century.
2. The divorce rate has increased steadily in the past half century.
3. It is more socially acceptable to not have children (through choice or abortion).
4. People are getting married later in life.
In relation to the commonly used CBO “household” income numbers, I think these issues may have had a huge effect on the perception of the widening income gap as follows:


Income Inequality: A Rising Tide Lifts All Yachts

Joe Stiglitz writes an excellent jeremiad on growing income inequality in the U.S in a recent issue ofVanity Fair. Most of what he said is factually correct, although claims about the average American being worse off (his claims, but more noisily those of various leftie groups) are simply wrong because of upward biases in inflation measures.
But so what? Comparisons matter, and it’s not just an issue of envy. Even though the average American is better off in real dollar terms than 20 years ago (despite our American national pastime of “bitching”), the concentration of economic power is growing most among a very few fragments of society. And, with the Supreme Court having handed the rich carte blanche to subsidize political candidates, the institutional framework for the economy can be changed in ways that disproportionately help the rich. Even though a rising tide may lift all boats, if giant yachts are lifted higher, the political backwash can make us paddlers of rowboats worse off!
