Things to Read on the Morning of May 30, 2014

Should-Reads:

  1. Kevin O’Rourke: Whither the Euro?: “All these difficulties were properly pinpointed by traditional optimal currency area theory…. Around the euro area periphery… capital inflows pushed up wages and prices. But what goes up does not come down so easily when there is no independent currency. Labor mobility within the euro area remains limited: young Irish workers emigrate to Australia or Canada, the Portuguese to Angola or Brazil. And with no federal budget to smooth asymmetric shocks, procyclical austerity, which exacerbates rather than ameliorates recessions, has been the policy weapon of choice during this crisis—whether imposed by the markets or by euro area politicians and central bankers. Mass unemployment in the periphery is exactly what theory would predict in such circumstances. Indeed, since 2008 we have learned that traditional optimal currency area theory was too sanguine about European monetary union. In common with much mainstream macroeconomics, it ignored the role of financial intermediaries such as banks, which link savers and borrowers. Many of the euro area’s most intractable problems stem from the flow of capital from the core to the periphery via interbank lending. When that capital stopped flowing, or was withdrawn, the resultant bank crises strained the finances of periphery governments. That further worsened bank balance sheets and credit creation, leading in turn to worsening economic conditions and rising government deficits—a sovereign bank doom loop that kept replaying…” The astonishing thing to me is how close the rhyme has been between the history of the travails of the interwar gold standard and the history of the twenty-first century Europe: terrible policies, repeated…

  2. Nick Bunker: CEO pay, equity and efficiency | Washington Center for Equitable Growth: “The median… CEO… made $10.5 million in 2013…. Is this rising pay for executives a major contributor to rising inequality? And if so, is it necessary for a well-functioning company?… The overall income distribution compiled by economists Emmanuel Saez and Thomas Piketty… threshold for the top 0.01 percent, $7.2 million…. Are they a significant share of that group?… Bakija… Cole… and… Heim… executives, managers, and supervisors were 30 percent of the top 1 percent and 42.5 percent of the top 0.1 percent. That occupation group doesn’t include managers from the financial sector… another 13.2 percent of the 1 percent and 18 percent of the top 0.1 percent…. There is evidence that CEOs as a class are overpaid…. Bertrand… and… Mullainathan of Harvard University show that CEO pay in the oil-and-gas industry is just as responsive to upticks in business fortunes due to luck or to random rises in oil prices, as to upticks in fortunes due to skill…. Betrand and Mullainathan argue that their result is evidence of the capture of the pay-setting process by CEOs…” Larry Summers likes to state that private-equity CEOs make as much–more–than public-company CEOs, and so it cannot be purely capture of the pay-setting process. I think that is an inference too far: talk to the princes of private equity and see how many public-company CEOs they would hire–I think the number is rather small…

  3. Nick Bunker: Tax cuts for the kids: “A number of reform-minded conservatives gathered at the American Enterprise Institute last week to celebrate the publication of a new book, Room to Grow…. One particularly interesting proposal is a call for ‘family friendly’ tax reform from economist Robert Stein…. Senator Mike Lee… child rebate set at $2,500 per child…. By focusing the tax cut on families that have children, the plan would help the development of future human capital…. The Stein-Lee plan does have some serious problems. The tax refund is not refundable…. And in an effort to make the plan revenue neutral, Lee would reduce tax credits for those at the bottom of the income ladder, as Chuck Marr at the Center for Budget and Policy Priorities has pointed out, making the issue of access even worse for low-income families. This conservative version of family friendly tax reform won’t become law anytime soon. Nor should it. But the recognition that increasing the disposable income of families is key to growth and mobility is certainly a welcome policy position from the right…” I am less sanguine: a non-refundable tax credit really is a non-starter from the get-go…

And:

  1. Marshall Steinbaum: Piketty versus Hassett: a primer on after-tax income and inequality: “Hassett’s praise for the potential for income redistribution to rectify injustice in market outcomes is notable, but in fact there have been many comparisons of pre- and post-tax-and-transfer income distributions, starting with this one from the Congressional Budget Office. Spoiler alert: they’re not very different from Piketty’s analysis. The reason? While transfer payments have increased (mostly thanks to an aging population), effective tax rates at the top of the income distribution have fallen sharply since 1980 (and we have the government debt to prove it)…” The big enchilada in all this is made up of the government-funded health programs. Evaulating them is difficult: they are boosts to reasonable assessments the real income of the poor, but it is not the case that the boost to the real income is the same as the amount of money spent by the government, for people would have gotten some charity care if there were neither Medicaid nor SCHIP. How much of a boost? That is very hard to assess…

  2. Nob Akimoto: Dear Nate Silver: Hire Better Editors: “I get that some folks thought we were being too hard on Silver over the Pielke stuff. Fine. But look at this recent piece of utter dreck. Anyone with a basic understanding of statistics (ie not Benjamin Morris) would know that you don’t suss out meaning in regressions using highly highly correlated numbers. Multicollinearity is an actual thing.  You have to consider interaction terms and It’s not a difficult thing for actual quantitative researchers to know. And you know what? A basic understanding of demographic and nutritional data would know that weight and height are HIGHLY correlated variables, especially in such a selectively created population like the NFL. Otherwise the result is just numerology. May as well hire Dan Brown to write articles about quarterbacks, seriously…”

  1. Daniel Kuehn: Facts & other stubborn things: It’s all about the discontinuities: “The other day I posted a suspicion of mine that Giles was very wrong about Piketty based on his treatment of discontinuous data series…. It was just a suspicion, but it was due to a problem that I think anyone who has worked with disparate data sources would immediately recognize. ]Howard Reed has gone through the data sources and he agrees….](http://www.theguardian.com/news/datablog/2014/may/29/piketty-chris-giles-and-wealth-inequality-its-all-about-the-discontinuities) This is one of the best commentaries on this argument that I’ve seen yet. He does a great job walking you through the problems in Giles’s work. What’s more amazing is that Giles seems to recognize the difference between what he did and what Piketty did, but he does not recognize it’s significance. btw – some comments by Phil Magness on Facebook suggest he doesn’t get this point either…”

  2. Howard Reed: Piketty, Chris Giles and wealth inequality: it’s all about the discontinuities: “I have identified three major discontinuities between the series for the years 1974-81…. Taken as a whole, these discontinuities imply that the estimate of the top 10% share of wealth is 22.5 percentage points lower by 2010 than it would have been if the wealth statistics had been collected on a consistent basis after 1974 as they were before 1974…. The main difference between the Piketty time series for UK inequality and the Giles time series for UK inequality, is that Piketty corrects his data series to allow for this 23 percentage-point drop (caused by changes in the methodology used to measure the wealth distribution), whereas Giles does not. While Giles has made it clear to me in private correspondence that he was fully aware of the discontinuities in the data series, he chose not to correct his final published data series to allow for them…”

  3. Paul Krugman: Cutting Back on Carbon: “Next week the Environmental Protection Agency is expected to announce new rules designed to limit global warming. Although we don’t know the details yet, anti-environmental groups are already predicting vast costs and economic doom. Don’t believe them. Everything we know suggests that we can achieve large reductions in greenhouse gas emissions at little cost to the economy. Just ask the United States Chamber of Commerce. O.K., that’s not the message the Chamber of Commerce was trying to deliver…. [But] the report considers a carbon-reduction program that’s probably considerably more ambitious than we’re actually going to see, and it… sounds like Dr. Evil intoning ‘one million dollars’. These days, it’s just not a lot of money…”

  4. Timothy Layton: If ObamaCare plans are only offering narrow networks, blame information asymmetry: “I think there is an additional issue to consider: the salience of information provided to consumers. In the Marketplaces, plans are differentiated mostly by three factors: Price, cost-sharing, and network. Anyone who has visited one of the state Marketplace websites knows that both price and cost-sharing information are very salient. However, information about a plan’s network is much murkier. Sure, anyone can follow a series of links to an insurer’s (often unclear) website and type in the name of specific providers to determine whether they belong to the insurer’s network. But, for most consumers, especially those with limited experience interacting with specific providers, a list of every doctor in the insurer’s network obviously does not provide a clear picture of the quality of the network. In economics, this lack of information about network quality is referred to as an information asymmetry. Information is asymmetric because insurers know more about the quality of their network than consumers.  In a famous paper that won him the Nobel Prize in Economics, George Akerlof showed that asymmetric information can produce market failures…”

Piketty versus Hassett: a primer on after-tax income and inequality

The Director of Economic Policy Studies at the American Enterprise Institute, Kevin Hassett, asserts that Thomas Piketty—the author of “Capital in the 21st Century”—is mistaken to focus on pre-tax and transfer income inequality because it obscures the countervailing increase in the generosity of the welfare state since 1979. According to this view, the political system has a natural way of dealing with a rise in the inequality of market-based income: transfer more income to the disadvantaged.

Is he correct? Well, according to the data Piketty and his coauthors compiled at the World Top Incomes Database, the evolution of market (pre-tax-and pre-transfer) income since 1979 looks like this:

052914-hassettpost-blog

But Hassett says that this view of pre-tax, pre-transfer income ignores the vast increase in government transfer payments—paid for by a progressive income tax—that is generously timed to counteract the “market” trend. Here’s a data series that shows the increase in gross transfer payments:

fred-chart[1]

Hassett’s praise for the potential for income redistribution to rectify injustice in market outcomes is notable, but in fact there have been many comparisons of pre- and post-tax-and-transfer income distributions, starting with this one from the Congressional Budget Office. Spoiler alert: they’re not very different from Piketty’s analysis. The reason? While transfer payments have increased (mostly thanks to an aging population), effective tax rates at the top of the income distribution have fallen sharply since 1980 (and we have the government debt to prove it). The CBO writes:

“The equalizing effect of transfers and taxes on household income was smaller in 2007 than it had been in 1979. The equalizing effect of transfers depends on their size relative to market income and their distribution across the income scale. The size of transfer payments—as measured in this study—rose by a small amount between 1979 and 2007. The distribution of transfers shifted, however, moving away from households in the lower part of the income scale. In 1979, households in the bottom quintile received more than 50 percent of transfer payments. In 2007, similar households received about 35 percent of transfers. That shift reflects the growth in spending for programs focused on the elderly population (such as Social Security and Medicare), in which benefits are not limited to low-income households. As a result, government transfers reduced the dispersion of household income by less in 2007 than in 1979.

Likewise, the equalizing effect of federal taxes depends on both the amount of federal taxes relative to income (the average tax rate) and the distribution of taxes among households at different income levels. Over the 1979–2007 period, the overall average federal tax rate fell by a small amount, the composition of federal revenues shifted away from progressive income taxes to less progressive payroll taxes, and income taxes became slightly more concentrated at the higher end of the income scale. The effect of the first two factors outweighed the effect of the third, reducing the extent to which taxes lessened the dispersion of household income.”

In short, income-redistribution policies failed to counteract growing income stratification over the past four decades. What’s more, these policies did less to equalize post-tax income now than it did in percentage terms in 1979, directly contradicting Hassett’s contention. Indeed, all the studies that have been done confirm the magnitude of income inequality as it has evolved whether you’re looking at pre- or post-tax-and-transfer income. Hassett should go back to defending inequality as economically efficient—at least that argument isn’t refutable with a swift look at the data.

The dangers of debt

The two authors of the newly released book “House of Debt,” Princeton University economist Atif Mian and University of Chicago economist Amir Sufi, will discuss their findings at an event today in downtown DC. Much of the attention to the book has been due to Mian and Sufi’s argument that the failure to sufficiently help underwater homeowners was a large reason for the severity of the Great Recession and the slow recovery from it. The argument, powerful on its own, has been given even more attention as “House of Debt” was released just two weeks after the publication of former Secretary Treasury Tim Geithner’s memoirs, in which Geithner defends the policy response to the financial crisis.

The debate about the proper response is a vital one, but focusing solely on that aspect of the book sells “House of Debt” short. Mian and Sufi present a powerful argument against debt and our economy’s overreliance on it. As the economists point out, debt is the anti-insurance. Debt amplifies economic shocks, making households, countries, and firms more economically fragile.

Throughout the book, Mian and Sufi give examples of ways we use debt that could be made more like equity and rely less on debt. Student debt, a topic of frequent conversation these days, is one example. The authors argue that student loans could be replaced by agreements to repay the investor with a fixed share of the student’s income every year. This repayment system would insure that students who fall on hard times wouldn’t be overwhelmed with debt payments.

The authors even speculate that sovereign debt could be amended so that repayment is based on a country’s gross domestic product. Given the connection between sovereign borrowing and declines in consumption in the Eurozone, Mian and Sufi may well be onto something.

Other work has shown how our banking sector is too reliant on debt financing. “The Bankers’ New Clothes” by economists Anat Admati of Stanford University and Martin Hellwig of the Max Planck Institute is a powerful argument for requiring financial firms to use more financing from their earnings or the stock market than through borrowing. The banks of the pre-crisis era were so fragile and toppled so easily because they were highly leveraged.

Of course, debt shouldn’t be abolished. Lending is a necessary and important part of our economy. But overreliance on debt threatens economic stability and prosperity. How and where we pull back on debt is a question we need to answer soon.

Estimates of World GDP, One Million B.C.-Present [1998]: My View as of 1998: The Honest Broker for the Week of May 24, 2014

Time to update this, as my thinking on a bunch of issues has changed over the past sixteen years. But first, as I think about how to so, let me reprint it…


I construct estimates of world GDP over the very long run by combining estimates of total human populations with largely-Malthusian estimates of levels of real GDP per capita.

Population

I take my estimates of human population from Kremer (1993), but it would not matter if I had chosen some other authority. All long-run estimates of human population that I have found are quite close together (with the exception of estimates of population around 5000 BC, where Blaxter (1986) estimates a population some eight times that of other authorities). Note that
this does not mean that the estimates are correct—just that they are roughly the same.

We Have a New Front Page at Equitable Growth!: Wednesday Focus: May 28, 2014

It is here: Homepage

It has lots of new stuff on it. Let me especially recommend:

Jesse Rothstein: Extended unemployment insurance remains critical: “New analyses of recent data covering unemployed workers during the Great Recession…

…and its aftermath indicate that the impact of unprecedented extensions of Unemployment Insurance on job uptake were smaller than previously thought while the benefits were extremely important to maintaining family incomes. The program helped sustain families and communities during an unusually long period of weak labor demand, helping to promote long-term labor market resiliency and higher future prosperity by helping the long-term unemployed remain out of poverty and attached to the labor market. Extended Unemployment Insurance benefits expired at the end of 2013, and Congress is now considering whether and how to reinstate them. The new data and analysis detailed in this issue brief—based on the roll-out of extended benefits in 2008-2010 and the roll-back that began in late 2011—indicate that… the downsides of UI extensions are smaller than in past economic downturns, and there are some previously unanticipated upsides…

Extending UI benefits for the long-term unemployed is one of the largest, ripest pieces of low-hanging economic-policy fruit that we are not picking right now.

And let me especially recommend, from my step-second-cousin:

Ariel Kalil: Economic inequality and the parenting time divide: “Researchers have not until recently thought about parents’ time investments in children…

…as a mechanism for the intergenerational transmission of economic status…. Jonathan Guryan and his colleagues used data from national time diaries to show that mothers with a college education or greater spend roughly 4.5 hours more per week directly interacting with their children than mothers with a high school degree or less…. My own national time use research, with… Rebecca Ryan and… Michael Corey, finds… [that] highly educated parents not only spend more time… they spend that time differently… shift the composition of their time as the child grows in ways that adapt to children’s development at different developmental stages… preschool… reading and problem solving… middle school… management of children’s life outside the home…. We still don’t know precisely why these patterns have emerged…

Things to Read on the Morning of May 29, 2014

Should-Reads:

  1. Michael Spence: Digitally enabled supply chains…. Economic activity… moved to any accessible country or region that had relatively inexpensive labor… complexity became manageable…. Many services related to intermediate and final demand require knowledge, expertise, information, and communication for their delivery. What they do not require is geographical nearness or the physical movement of goods…. Now comes a second, potentially even more powerful, wave of digital technology that is replacing labor in increasingly complex tasks. This process of labor substitution and disintermediation has been underway for some time in service sectors–think of ATMs, online banking, enterprise resource planning, customer relationship management, mobile payment systems, and much more…. With a huge potential global market to amortize the upfront fixed costs of design and testing, the incentives to invest are compelling…. Unlike the preceding wave of digital technology, which motivated firms to gain access to and deploy underutilized pools of valuable labor around the world, the driving force in this round is cost reduction via the replacement of labor…. Meanwhile, the impact of robotics… is not confined to production… the impact on logistics is no less transformative…”

  2. Albert Wenger: Computers and Wages: “There is good reason to believe that computers are substitutes for labor in general. Their apparent complementarity with skilled labor was the result of substituting skilled labor for unskilled labor rather than being based on a fundamental technological complementarity…. Let’s look instead at the type of skilled work that to date has been boosted by the use of computers…. As we have used computers to substitute for unskilled labor we have created massive additional profits. Skilled labor has been given some share of that but that share is limited to roughly the marginal product by competition between engineers. That leaves a large pool to be split between top management and capital. And in that bargaining situation it turns out that top management is surprisingly well positioned. Why? Because there is a large principal-agent problem between board members and the capital that they represent…. We should not expect the benefits for skilled labor to last forever. Instead, we will gradually see computers substituting for those as well and only top management (and capital) continuing to benefit. And so the current idea that we can somehow educate our way out of this divergence without the need for more profound changes in how we think about income is likely deeply flawed…”
