Lottery Winners Don't Get Healthier

Alex Tabarrok at Marginal Revolution had a great post last week, Lottery Winners Don't get Healthier (also enjoy the url.)

Wealthier people are healthier and live longer. Why? One popular explanation is summarized in the documentary Unnatural Causes: Is Inequality Making us Sick?

The lives of a CEO, a lab supervisor, a janitor, and an unemployed mother illustrate how class shapes opportunities for good health. Those on the top have the most access to power, resources and opportunity – and thus the best health. Those on the bottom are faced with more stressors – unpaid bills, jobs that don’t pay enough, unsafe living conditions, exposure to environmental hazards, lack of control over work and schedule, worries over children – and the fewest resources available to help them cope. 

The net effect is a health-wealth gradient, in which every descending rung of the socioeconomic ladder corresponds to worse health.

If this were true, then increasing the wealth of a poor person would increase their health. That does not appear to be the case. In important new research David Cesarini, Erik Lindqvist, Robert Ostling and Bjorn Wallace look at the health of lottery winners in Sweden (75% of winnings within the range of approximately $20,000 to $800,000) and, importantly, on their children. Most effects on adults are reliably close to zero and in no case can wealth explain a large share of the wealth-health gradient:

In adults, we find no evidence that wealth impacts mortality or health care utilization.... Our estimates allow us to rule out effects on 10-year mortality one sixth as large as the crosssectional wealth-mortality gradient.

The authors also look at the health effects on the children of lottery winners. There is more uncertainty in the health estimates on children but most estimates cluster around zero and developmental effects on things like IQ can be rejected (“In all eight subsamples, we can rule out wealth effects on GPA smaller than 0.01 standard deviations”).

(My emphasis above)

Alex does not emphasize the most important point, I think, of this study.  The natural inference is, The same things that make you wealthy make you healthy. The correlation between health and wealth across the population reflect two outcomes of the same underlying causes.

Universal Basic Income

Universal Basic Income is in the news. Charles Murray wrote a thoughtful piece in the Wall Street Journal Saturday Review. The Swiss overwhelmingly rejected a referendum -- but on a proposal quite different from Murray's.

Murray proposes that "every American citizen age 21 and older would get" $10,000 per year "deposited electronically into a bank account in monthly installments." along with essentially a $3,000 per year health insurance voucher.

The most important part of Murray's proposal: UBI completely replaces

 Social Security, Medicare, Medicaid, food stamps, Supplemental Security Income, housing subsidies, welfare for single women and every other kind of welfare and social-services program, as well as agricultural subsidies and corporate welfare. 

There is a lot to commend this idea. First, it would reduce the dramatic waste in the current system:

Under my UBI plan, the entire bureaucratic apparatus of government social workers would disappear

Moreover, the bulk of government spending now does not go to people who are really poor. SSI and medicare go to old people, many of whom are quite well off. Housing subsidies such as the mortgage interest deduction go to people with big mortgages and big tax rates -- nor poor people. Murray doesn't really emphasize this point, but his proposal is far more progressive than the current transfer system.

Second, it would reduce the very high disincentives of the current system, which traps people.

 Under the current system, taking a job makes you ineligible for many welfare benefits or makes them subject to extremely high marginal tax rates. Under my version of the UBI, taking a job is pure profit with no downside until you reach $30,000—at which point you’re bringing home way too much ($40,000 net) to be deterred from work by the imposition of a surtax.

Ideas had sex

Why are we so much better off than our ancestors? Why did this process only start where and when it did, in Western Europe, not in Rome or China?

Deirdre McCloskely has an excellent essay in the Saturday Wall Street Journal Review.

Her answer: "Ideas started having sex," a glorious sentence she attributes to Matt Ridley.

"The idea of a railroad was a coupling of high-pressure steam engines with cars running on coal-mining rails. The idea for a lawn mower coupled a miniature gasoline engine with a miniature mechanical reaper. "

And so on. She is exactly right. We tend to focus on the original idea, the basic science. That's necessary, but 99% of growth comes from elaboration, implementation, and the marriage of ideas -- sex in the sense of genes combining and making new things.

What's the bar for these hookups?

The answer, in a word, is “liberty.” Liberated people, it turns out, are ingenious.

Also,

...equality. ...not an equality of outcome... equality before the law and equality of social dignity.

Though, as she points out at length, the social dignity, property rights, and equality of entrepreneurs has always been a dicey matter.

McArdle Nugget

Megan McArdle has produced a timely nugget of wise prose

I would cross income inequality itself off the list of priorities. Far greater concerns include: absolute suffering among those with low incomes; a socioeconomic structure that seems to be ossifying into a hierarchy of professional classes; and a decline in income mobility, which is to say, in equality of opportunity. It doesn’t really matter whether Bill Gates has some incomprehensible sum of money at his disposal. It does matter a great deal whether there are Americans in desperate want. And of course, it matters whether anyone with the aptitude and motivation can become the next Bill Gates, or only a handful of privileged people who are already well off.

I also submit that the importance of the issue is inversely proportionate to the ease of solution. The government is very good at taxing income of some Americans and writing checks to others. (Whether you think it should do this is, of course, a different question.)

[JC: Actually, I'm not so sure the government is very good at this. Our tax code is a mess. Our income transfers largely go to middle class and well connected businesses. Our system of writing checks includes numerous 100% + marginal tax rates and other disincentives. Despite the one of the most progressive tax systems on the planet, there are still schizophrenics on the streets.]

It is very bad at preparing someone to live a solid and fulfilling life of work and community, which is one reason we mostly leave that job to parents.

Government is also not well suited to creating a lot of satisfying and remunerative jobs. It can contribute to productivity and help companies to flourish, for example through basic research and by maintaining a competent legal and regulatory system. And it can directly create a few jobs providing government services; these have been, for many communities at many times, a stepping stone to the middle class.

... For the most part, the best the government can do is to avoid stepping on the creation of satisfying and remunerative jobs; no nation on earth seems to have figured out how to generate “good jobs” for everyone. 

[JC: I think she means no government on earth.. "nations" have figured it out!]

Sanders multiplier magic

The critiques of Gerald Friedman's analysis of the Sanders economic plan  continue. The latest and most detailed and careful so far is by David and Christina Romer.

Bottom line:

1. The central idea in Friedman's analysis is that taking $1 from Peter to give to Paul raises overall income by 55 cents.  From this, you get multipliers from raising taxes and spending, from higher minimum wages, more unions, and so forth. 
2. I chuckle a little bit that so many economists who previously liked multipliers now don't like their logical conclusions. 
3. The Romers charge a serious, elementary arithmetic mistake in treating levels vs. growth rates. If they're right Friedman's whole analysis is just wrong on arithmetic.

The analysis

One might have expected that a sympathetic analysis of the Sanders plan would say, look, this is going to cost us a bit of growth, but the fairness and (claimed) better treatment of disadvantaged people are worth it.

Friedman's having none of that. In his analysis, the Sanders plan will also unleash a burst of growth, claims for which would make a fervent supply-sider like Art Laffer blush.

"The Sanders program... will raise the gross domestic product by 37% and per capita income by 33% in 2026; the growth rate of per capita GDP will increase from 1.7% a year to 4.5% a year." And, apparently, raise the growth rate permanently.

Inequality and Economic Policy Published

The Hoover Press put up for free the chapters of Inequality and Economic Policy: Essays In Memory of Gary Becker, edited by Tom Church, John Taylor, and Christopher Miller. You can of course still buy the book for a reasonable $14.95.

This includes the published version of my essay Why and How We Care about Inequality, also available on my webpage.  Bryan Caplan was kind enough to cover it positively last week, now you can read the original. I put a draft up on this blog last year, so I won't repeat it all today. As usual, the published version is better.

An essay. It's an overview of what a growth-oriented policy program might look like. Regulation, finance, health, energy and environment, taxes, debt social security and medicare, social programs, labor law, immigration, education, and more. There is a more permanent version here and pdf version here. This version shows on blogger, but if your reader mangles it, the version on my blog or one of the above will work better.

I wrote it the Focusing the presidential debates initiative. The freedom of authors in that initiative to disagree is clear.

Economic Growth

Growth is central

Sclerotic growth is the overriding economic issue of our time. From 1950 to 2000 the US economy grew at an average rate of 3.5% per year. Since 2000, it has grown at half that rate, 1.7%. From the bottom of the great recession in 2009, usually a time of super-fast catch-up growth, it has only grown at two percent per year.² Two percent, or less, is starting to look like the new normal.

Small percentages hide a large reality. The average American is more than three times better off than his or her counterpart in 1950. Real GDP per person has risen from $16,000 in 1952 to over $50,000 today, both measured in 2009 dollars. Many pundits seem to remember the 1950s fondly, but $16,000 per person is a lot less than $50,000!

If the US economy had grown at 2% rather than 3.5% since 1950, income per person by 2000 would have been $23,000 not $50,000. That’s a huge difference. Nowhere in economic policy are we even talking about events that will double, or halve, the average American’s living standards in the next generation.

Even these large numbers understate reality.

Minimum wage and mechanization

A while ago I opined that higher minimum wages might lead companies like McDonalds to substitute to machines. A former student sends me:

here's a photo I took in the McDonald's on the Champs-Élysées, Paris, of the screens where customers can place their orders and pay. After a short wait, you pick up your burger and fries at the counter.

I did not ask just why he is eating at McDonalds in France!

Wages and inflation

Marty Feldstein has a very interesting opinion piece on Project Syndicate. His main point is that micro distortions from social programs (and taxes, labor laws, regulations etc.) are leading many people not to work, and is well stated.

An introductory paragraph poses a puzzle to me, however,

Consider this: Average hourly earnings in May were 2.3% higher than in May 2014; but, since the beginning of this year, hourly earnings are up 3.3%, and in May alone rose at a 3.8% rate – a clear sign of full employment. The acceleration began in 2013 as labor markets started to tighten. Average compensation per hour rose just 1.1% from 2012 to 2013, but then increased at a 2.6% rate from 2013 to 2014, and at 3.3% in the first quarter of 2015.

These wage increases will soon show up in higher price inflation. 

This is a common story I hear. However I hear another story too -- the puzzle that the share of capital seems to have increased, and that real wages have not kept up with productivity.

So, maybe we should cheer -- rising real wages means wages finally catch up with productivity, and do not signal inflation. The long-delayed "middle class" (real) wage rise is here.

I'd be curious to hear opinions, better informed than mine, about how to tell the two stories apart.  

Uber and Occupational Licenses

I enjoy moments of agreement, and common sense in publications where it's usually absent. Eduardo Porter writing in the New York Times on the lessons of Uber vs. Taxis for occupational licensing is a nice such moment.

[Uber's] exponential growth confirms what every New Yorker and cab riders in many other cities have long suspected: Taxi service is woefully inefficient. It also raises a question of broader relevance: Why stop here?

Just as limited taxi medallions [and ban on surge pricing, and the mandated shift change  -JC] can lead to a chronic undersupply of cabs at 4 p.m., the state licensing regulations for many occupations are creating bottlenecks across the economy, raising the prices of many goods and services and putting good jobs out of reach of too many Americans.

... like taxi medallions, state licenses required to practice all sorts of jobs often serve merely to cordon off occupations for the benefit of licensed workers and their lobbying groups, protecting them from legitimate competition.

...“Lower-income people suffer from licensing,” Professor Krueger told me. “It raises the costs of many services and prevents low-income people from getting into some professions.

This is an all too often overlooked effect of so much government-induced cartelization. The costs of higher prices are paid by middle and lower income people. And many job opportunities are denied to lower income people.

Piketty Facts

Most Piketty commentary (like the Deridre McCloskey review I blogged earlier) focuses on the theory, r>g, and so on. After all, that's easy and you don't have to read hundreds of pages.

"Challenging the Empirical Contribution of Thomas Piketty's Capital in the 21st Century" by Phillip W. Magness and Robert P. Murphy is one of the first deep reviews of the facts that I have seen. I haven't read it yet, but the abstract looks promising:

Thomas Piketty's Capital in the 21st Century has been widely debated on theoretical grounds, yet continues to attract acclaim for its historically-infused data analysis. In this study we conduct a closer scrutiny of Piketty's empirics than has appeared thus far, focusing upon his treatment of the United States. We find evidence of pervasive errors of historical fact, opaque methodological choices, and the cherry-picking of sources to construct favorable patterns from ambiguous data. Additional evidence suggests that Piketty used a highly distortive data assumption from the Soviet Union to accentuate one of his main historical claims about global “capitalism” in the 20th century. Taken together, these problems suggest that Piketty’s highly praised and historically-driven empirical work may actually be the book’s greatest weakness.

Comments on the paper welcome. If I get a chance to read it I'll post some.

Time use of the non-employed

Source: New York Times

The decline in labor force participation means that a larger and larger fraction of the population, including many prime-age men, are not working and not actively looking for work.

What do they do all day? The New York Times has a lovely article answering that question.

I took a screenshot at left to advertise the post, but go to the Times where the graph is interactive.

Next question, where does the money come from?

Understanding the lives of people in this predicament seems to me a useful step to understanding the big decline in participation.

Inequality at WSJ -- the oped

This is a Wall Street Journal oped on inequality. With 30 days passed, I can post it here. It's a much edited version of my evolving "Why and How we Care About Inequality" essay.


What the ‘Inequality’ Warriors Really Want

Progressives decry inequality as the world’s most pressing economic problem. In its name, they urge much greater income and wealth taxation, especially of the reviled top 1% of earners, along with more government spending and controls—higher minimum wages, “living” wages, comparable worth directives, CEO pay caps, etc.

Inequality may be a symptom of economic problems. But why is inequality itself an economic problem? If some get rich and others get richer, who cares? If we all become poor equally, is that not a problem? Why not fix policies and problems that make it harder to earn more?

McCloskey on Piketty and Friends

Deirdre McCloskey has written an  excellent essay reviewing Thomas Piketty’s Capital in the Twenty-First Century.

As an economic historian and historian of economic ideas, McCloskey can place the arguments into the framework of centuries-old ideas (and fallacies) as few others can. She has read philosophy and "social ethics." She can even knowledgeably review the literary references.

Her central point: "trade-based betterment," (she wisely avoids "capitalism" to emphasize that  the focus on "capital" is about a hundred years out of date) has raised living standards by factors of 30 or more -- much more if you think about health, freedom, lifespan, tavel, etc. unavailable at any price in 1800;  it has led to much greater equality in many things that count, such as consumption, health and so on; and stands to do so again if we do not kill the goose that laid these golden eggs.  From late in the review,

Redistribution, although assuaging bourgeois guilt, has not been the chief sustenance of the poor....If all profits in the American economy were forthwith handed over to the workers, the workers ... would be 20 percent or so better off, right now....

But such

one-time redistributions are two orders of magnitude smaller in helping the poor than the 2,900 percent Enrichment from greater productivity since 1800. Historically speaking 25 percent is to be compared with a rise in real wages 1800 to the present by a factor of 10 or 30, which is to say 900 or 2,900 percent. 

As a too-long post on a far-too-long review of a enormously-too-long book, I'll pass on some particularly good bits with comment.

On the long history of fashionable worrying:

Inequality at WSJ

"What the Inequality Warriors Really Want" a Wall Street Journal oped on inequality. It's a much edited version of my evolving "Why and How we Care About Inequality" essay. Any writers will appreciate the pain that cutting so much caused.

As usual I can't post the whole thing for 30 days, but you might find the WSJ short version interesting, especially if you couldn't slog through the whole thing. Their comments might be fun too.

Chicken and Egg Inequality

The FT's Martin Wolf weighs in on "Why inequality is such a drag on economies"

This is the question that was bugging me last week. Why is inequality a problem in and of itself, rather representing a symptom of problems that should be fixed for their own sake?

Since last week's review of these ideas was rather scathing, I hoped Wolf would offer some new, and better tested ideas.

Alas, and interestingly, no.

Envy and excess

In the inequality post, I puzzled over the following conundrum:

Why does it matter at all to a vegetable picker in Fresno, or an unemployed teenager on the south side of Chicago, whether 10 or 100 hedge fund managers in Greenwich have private jets? How do they even know how many hedge fund managers fly private? They have hard lives, and a lot of problems. But just what problem does top 1% inequality really represent to them? 

I emphasized the quantity issue here. His grandfather in the 1930s watched movies and saw glamorous lifestyles way beyond what he could achieve. Increasing inequality is about larger numbers who live a lavish lifestyle. And the claim is that increasing inequality is changing behavior.

There is a view motivating the left that inequality is just unjust so we - the federal government is always "we" -- have to stop it. If they'd say that, fine, we could have  productive discussion.

But they say, and I was going after in the post, all sorts of other things. That inequality will cause poor people to spend too much, that it will cause them to rise in political rebellion, for example. For that to happen, for the presence of the rich to affect their behavior in any way, they have to know about how the exploding 1/10 of 1% live, and how many of them there are. Which just doesn't make any sense.

Paul Krugman had a few revealing columns over the weekend. (No, not the endlessly repeated Say's Law calumny. I trust you all understand how empty that is.)

Returns to unwanted education

In my inequality post, I wrote, somewhat speculatively,

The returns to education chosen and worked hard for are not necessarily replicated in education subsidized or forced.

Marginal Revolution points to a nice new paper by Pierre Mouganie making this point. From the abstract:

In 1997, the French government put into effect a law that permanently exempted young French male citizens born after Jan 1, 1979 from mandatory military service while still requiring those born before that cutoff date to serve. ... conscription eligibility induces a significant increase in years of education, which is consistent with conscription avoidance behavior. However, this increased education does not result in either an increase in graduation rates, or in employment and wages. Additional evidence shows conscription has no direct effect on earnings, suggesting that the returns to education induced by this policy was zero.

Why and how we care about inequality

Note: These are remarks I gave in a concluding panel at the Conference on Inequality in Memory of Gary Becker, Hoover Institution, September 26 2014. The conference program here, and John Taylor's summary here, where you can see the great papers I allude to. I'll probably rework this to a more general essay, so I reserve the right to recycle some points later.

Why and How We Care About Inequality

Wrapping up a wonderful conference about facts, our panel is supposed to talk about “solutions” to the “problem” of inequality.

We have before us one “solution,” the demand from the left for confiscatory income and wealth taxation, and a substantial enlargement of the control of economic activity by the State.

Note I don’t say “redistribution” though some academics dream about it. We all know there isn’t enough money, especially to address real global poverty, and the sad fact is that government checks don’t cure poverty. President Obama was refreshingly clear, calling for confiscatory taxation even if it raised no income. “Off with their heads” solves inequality, in a French-Revolution sort of way, and not by using the hair to make wigs for the poor. The agenda includes a big expansion of spending on government programs, minimum wages, “living wages,” government control of wages, especially by minutely divided groups, CEO pay regulation, unions, “regulation” of banks, central direction of all finance, and so on. The logic is inescapable. To “solve inequality,” don’t just take money from the rich. Stop people, and especially the “wrong” people, from getting rich in the first place.

In this context, I think it is a mistake to accept the premise that inequality, per se, is a “problem” needing to be “solved,” and to craft “alternative solutions.”

Just why is inequality, per se, a problem?

Suppose a sack of money blows in the room. Some of you get $100, some get $10. Are we collectively better off? If you think “inequality” is a problem, no. We should decline the gift. We should, in fact, take something from people who got nothing, to keep the lucky ones from their $100. This is a hard case to make.

One sensible response is to acknowledge that inequality, by itself, is not a problem. Inequality is a symptom of other problems. I think this is exactly the constructive tone that this conference has taken.

But there are lots of different kinds of inequality, and an enormous variety of different mechanisms at work. Lumping them all together, and attacking the symptom, “inequality,” without attacking the problems is a mistake. It’s like saying “fever is a problem. So medicine shall consist of reducing fevers.”

S&P economists and inequality

Neil Irwin at the New York Times writes interesting coverage of a report titled "How Increasing Income Inequality Is Dampening U.S. Economic Growth, And Possible Ways To Change The Tide" by S&P economists.

The article starts with interesting comments about business economists

...you have to know a little bit about the many tribes within the world of economics. There are the academic economists...many labor in the halls of academia for decades writing carefully vetted articles for academic journals that are rigorous as can be but are read by, to a first approximation, no one. 

Ouch!
