Most People Don’t Graduate From College

A persistent problem with MSM coverage of young people is the fairly relentless focus on attendees and graduates of selective colleges. So I think Jamelle Bouie’s response to the latest NYT Magazine article on twentysomethings is spot on. There’s good in the piece, but:

That said, my main problem with the piece was simply the fact that there wasn’t much of an attempt at making class distinctions. It delves into the “extended adolescence” of relatively sheltered graduates from major universities, but what about the mass of 20-somethings who either didn’t go to college, or pursued degrees at community colleges and local universities? I graduated from a high school of roughly 2,400 people in 2005, and judging from the Facebook profiles of those I graduated with, many of my former classmates have built fairly adult lives for themselves. Most have jobs and live independently of their parents. Some have spouses or long-term partners, a few have children. For those who do live with their parents, it has less to do with maturity, and more to do with the terrible job market. Obviously, anecdotes can’t substitute for statistical data, but I’d wager that the above is true for many 20-somethings of modest means.

Most Americans don’t have bachelor’s degrees, and this is true at all age cohorts. What’s more, most Americans who do go to college don’t go to schools with selective admissions. Obviously, lots of people with BAs from selective schools have problems in life, and their problems (our problems, my problems) count in the moral scheme of things. But the less-privileged have more pressing problems and are also more numerous.

Dropout Factories

My friend Ben Miller and Phuong Ly has a great piece in The Washington Monthly about college dropout factories, schools that earn nice money enrolling students but don’t seem to manage to graduate many or teach anyone useful skills.

The Partisan Fed?

It’s impolite to raise such concerns in polite circles, but it’s worth noting that there’s some evidence that the Federal Reserve’s monetary policy has historically been biased against Democratic elected officials. Is that going on today? We’ll never know for sure. We do know that presidents have some authority over the Fed. But when you use that authority to renominate the incumbent Republican GOP Fed Chair, and then don’t fill the other vacancies on the Fed board in a timely manner you’re virtually asking to be punished with policy biased against your political interests.

Where Have All the African Revolutionaries Gone?

Chris Blattman and William Reno (PDF) wonder why armed conflict in Africa has taken on a decreasingly ideological character in recent decades. You still have rebels, but you have fewer revolutionaries.

I’d say global politics has in general become less ideological in most places. US domestic politics is an exception to this overall trend, but you see it in a lot of other places, from the domestic politics of European countries to geopolitical rivalries to intrastate conflict in Africa. My impression is that politics wasn’t especially “ideologically” before the late 18-th century and perhaps post-1991 we’re just returning to the long-term norm.

Something to Read

Steve Randy Waldman’s writeup of economics bloggers’ meeting with Treasury officials makes for pretty interesting vacation reading.

Where’s the Brazilian Right

Latest polling of the Brazilian election:

Dilma Rousseff holds a significant advantage over fellow presidential candidate Jose Serra just months before an election takes place in Brazil, according to a poll by Ibope. 43 per cent of respondents would vote for Rousseff of the ruling Workers’ Party (PT) in the October ballot, up three points since June.

Jose Serra of the Brazilian Party of Social Democracy (PSDB) is second with 32 per cent, down three points. Marina Silva of the Green Party (PV) is third with seven per cent.

The funny thing here is that none of these seem to be the names of right-of-center parties. I know something similar happened in Portugal where the main center-right party is called the Partido Social Democrata (Social Democrats) and the center-left party is the Socialist Party. Is that’s what’s happening in Brazil with the PSDB being a de facto center-right party despite its left-sounding name?

Purchasing Power Parities

John Quiggin concludes a post with a “very wonkish note” on Purchasing Power Parities:

(Very wonkish note) Although PPP numbers are often treated as if they are are raw facts, they are index numbers which are fundamentally imprecise (even if the underlying data is perfectly accurate, which it isn’t). From work I did with Steve Dowrick in the 1990s, I estimate the difference between upper and lower bounds at around 10 per cent. It’s likely that any bias in PPP numbers favors the US. That’s because they are a generalized kind of Laspeyres index, and (as I understand it) the base data is derived largely from Europe.

I call for more wonky blog posts about PPP data. This kind of information is sort of the most dangerous kind—it’s easy to look up, it produces precise-looking ordinal lists, but few people (certainly not me) really understands how it works. Take a country like China, where the nominal GDP per capita is about $3,800 but the PPP GDP per capita is a much-higher $6,600. China is also a very large and diverse society with substantial class divisions. Presumably the typical “basket of goods” purchased by an urban professional is very different from the basket of goods of a peasant farmer. So whose purchasing power are we talking about here? I think relatively few of us who mention this data now and again really have a firm grasp on it.

Maine Fact of the Day

Maine is the whitest state in the union, edging out long-time rival Vermont. In fact, the state is so white that white people even cook the Mexican food.

Ideological Positioning

A colleague mentioned to me the other day that I’m “pretty conservative” on some state and local government issues, with reference to some recent posts on occupational licensing. Someone on twitter asked if I’m trying to score a date with a Cato staffer. I’m not. And I’m not. And I think that whole framing represents a bad way of understanding the whole situation.

I think it’s pretty clear that, as a historical matter of fact, the main thing “the state” has been used to do is to help the wealthy and powerful further enrich and entrench themselves. Think Pharaoh and his pyramids. Or more generally the fancy houses of European nobility, the plantations of Old South slaveowners, or Imelda Marcos’ shoes. The “left-wing” position is to be against this stuff—to be on the side of the people and against the forces of privilege. It’s true that some useful egalitarian activism over the past 150 years has consisted of trying to get the state to take affirmative steps to help people—social insurance, the welfare state, infrastructure, schools—but dismantling efforts to use the state to help the privileged has always been on the agenda. Don’t think to yourself “we need to regulate carbon emissions therefore regulation is good therefore regulation of barbers is good.” Think to yourself “we can’t let the privileged trample all over everyone, therefore we need to regulate carbon emissions and we need to break the dentists’ cartel.”

Traffic Jams

I feel certain that if Financial Times did an article about how some country’s determination to provide free bags of rice to all its citizens was leading people to spend a huge amount of time standing on line waiting for rice, that they would highlight the fact that this is what happens when you don’t price things correctly. There’s only so much rice. There are only so many hander-outers of rice. If you try to make the rice free to everyone, you’re going to get lines and shortages.

At any rate, as Clive Cookson points out in the FT a comparable problem exists on most countries’ roadways:

Access to these roadways is generally either free, or else set a price determined by something other than the scarcity of space on the roadway. And yet any given street or highway can only fit so many cars at a time. So when the price is unrelated to the scarcity, you get shortages and queuing—traffic jams. But weirdly a whole long article on improved traffic management just leaves this as a throwaway line “In the long term, variable road pricing or tolls on main roads may provide a partial answer but these are not yet technically or politically feasible in most countries.”

That’s fair enough, but none of the other stuff in the article is yet technically or politically feasible in most countries either. And the question of what is and isn’t “politically feasible” is itself amenable to influence by media coverage.

The Truth About Japan

I would highly recommend that you take a look at Adam Pozen’s talk “The Realities and Relevance of Japan’s Great Recession – Neither Ran nor Rashomon“. His point is that poor Japanese economic performance, though of course not unrelated to the bursting of asset bubbles, was fundamentally caused by policy errors and that when better policies were implemented growth became strong:

What was necessary was the clean-up and recapitalization of the banking system, the further loosening of monetary policy (to the extent possible given that interest rates were at zero), and the avoidance of any further premature fiscal tightening, as I set out in Posen (1998, 1999a, and 2001b). This was obviously not a simple list, economically or politically. Yet, it was also not a list of the impossible, it emphasized demand side factors, and was a list that seemed all the more plausible when Japanese policymakers recognized that Japan was not doomed to a permanently low trend growth rate – a belief that had bedevilled both fiscal and monetary policy decisions in Japan for much of the 1990s.

Japan’s new economic leadership in the early 2000s, Prime Minister Junichiro Koizumi, Cabinet Office and later Financial Services Minister Heizo Takenaka, and Bank of Japan Governor Toshihiko Fukui, turned matters around. They reversed monetary policies that contributed to deflation, turned the fiscal impulse to average net zero (see figure 5), and forced bad loan write- offs and recapitalization by the Japanese banks (figure 6).10 What few seem to appreciate, either inside or outside of Japan, is just how strong the resulting Japanese recovery from 2002-2008 was. It was the longest unbroken recovery of Japan’s postwar history, and, while not as strong as pre-bubble Japanese performance, was in fact stronger than the growth in comparable economies even when fuelled by their own bubbles.

People can get confused about Koizumi-era Japan’s economic performance because demographics were driving a pretty rapid reduction in the number of workers. That drags down overall output. But even though China’s GDP is much larger than Switzerland, Switzerland is still much richer and its workers are much more productive.

Posen’s piece is important, because I fear that historical evidence of poor economic performance in the wake of asset price bubbles bursting is creating a mood of dangerous complacency. You can read that as evidence that we’re destined to experience an extended period of poor growth, but you can also read it as evidence that what normally happens after a bust is that policymakers implement an ineffective response. And as Posen argues, accepting the view that slow growth is inevitable is a major cause of ineffective policy and becomes self-fulfilling. Japan started growing once it got some policymakers who believed it was possible for Japan to grow, and thus that they would try pro-growth things and try them on a large scale.

The Route North

For the long drive, I’ve tried to assemble a playlist of state-appropriate songs that take us from DC to Maine as follows:

1. For Washington, DC it’s the Postal Service “The District Sleeps Alone Tonight.”
2. For Maryland, it’s REM “(Don’t Go Back to) Rockville.”
3. Then Delaware, Promise Ring “Is This Thing On?”
4. New Jersey is Less Than Jake “Never Going Back to New Jersey.”
5. I know a million New York songs, but since the route just involves a quick jaunt across the Cross Bronx Expressway I’m going with Boogie Down Productions, “South Bronx.”
6. I think from the title that Rainer Maria’s “CT Catholic” is Connecticut, though the only specific place referenced is the BQE in New York. But I guess that’s how you’d get from Williamsburg to Connecticut.
7. Next up, The Get-Up Kids “Mass Pike.”
8. There don’t seem to be any real songs about New Hampshire, but the “Granite State of Mind” parody is hilarious.
9. John Linnel’s “Maine” is pretty great.

This ended up being a more emo list than I’d intended. Peppy bands should write more songs about locations in the Northeast.

The Message

Voting is mostly about the objective situation, not about what people say about the election. But insofar as talking is inevitable, you may as well do it well. Looking at the Democrats message heading into the midterms it all seems mighty backward looking: “we accomplished a bunch of stuff / the economy’s not really our fault / etc.” Missing here is what you’d call the narrative about what Democrats envision the 112th Congress as doing.

Suppose you voted for Democrats in 2006 and 2008 because you wanted to see action on health reform, energy reform, and immigration reform. Now you’re happy that health reform happened, but sad that energy reform and immigration reform didn’t happen. If Democrats come back this fall with a surprisingly good result—diminished but still robust majorities—are those things going to happen? Or are the remaining pieces of that agenda dead either way?

Let’s Go Away for a While

I’m off this morning to a strange and distant land for a bit of vacation. Specifically, my girlfriend and I will be driving up to sunny Cambridge, MA today and then pushing forward Sunday morning to my dad’s summer place in Brooklin, ME recently profiled by the Internet’s own Emily Gould. My hope is to enjoy some breeze, nice views, lobster rolls, peekytoe crab, and perhaps some sea kayaking.

Anyways, I like blogging so I’ll put some posts up while I’m gone, but obviously at a much-reduced pace and possibly focused on photos of quaint stuff.

It Takes a Congress

Something to add to the growing “what’s Obama done wrong” literature and the “what’s wrong with the ‘what’s Obama don’t wrong’ literature” literature is that too often these discussions seem to me to forget that the United States Congress is composed of free and equal human beings who are responsible for their own actions. For example, it may or may not be the case that a different approach on the part of Barack Obama or his staff would have caused Ben Nelson to do different things low these past several months, but it’s absolutely certain that had Nelson wanted to do different things that different things would have happened.

Given that to err is human, I think we can take it for granted that some errors existed in the White House’s approach to legislative negotiations. But it’s also clear that members have their own volition. A skeptical Blanche Lincoln could have responded to the $800 billion stimulus request by asking Barack Obama “what does Christina Romer think? will this really fill the output gap?” Vulnerable House members could have challenged Rahm Emannuel “if things turn out to be worse than you guys expect, we’re all going to lose in the midterms—wouldn’t it be more prudent to build in provisions for additional stimulus if necessary?” The members who insisted on exempting auto dealerships from the jurisdiction of the Consumer Financial Protection Bureau could have said “you know what, Michael Barr is right, this doesn’t make any sense; we should do the right thing and tell the dealers to stop whining.”

Which is just to say that in a lot of respects members of congress seem to me to benefit from the soft bigotry of low expectations. Nobody really expects them to do the right thing or to ask smart questions or to listen to experts rather than engage in random acts of political posturing. So when they do bad stuff, we blame the White House for not doing a better job of preventing them from doing bad stuff. And fair enough—dealing with congress is an important part of the job. But you also do need to blame the people who are doing the bad deeds.

Rawls and the Open Economy

Via Mark Thoma, Daniel Little offers a short but sweet account of how far contemporary America falls short of the Rawlsian ideal of a “property owning democracy.”

Consider immigration. Immigration exacerbates inequality among the native born, but makes most Americans better off, and of course makes immigrants better-off. Best possible policy response, according to me and according to Rawls, is to let immigrants come and do redistributive taxation. But what’s second-best? According to me, you let the immigrants in anyway. After all, most people benefit and the interests of the immigrants themselves are very relevant here—they’re much poorer than anyone in America. According to Rawls, however, for some reason the interests of Mexicans don’t count unless Mexico falls beneath some kind of threshold of humanitarian subsistence. That doesn’t make sense to me.

Of course I’m not the first person to disagree with Rawls on this point about the interests of foreigners and global aspects of international justice. But I think that the people who think about these things on a philosophical level are sometimes not paying attention to the interplay of foreign and domestic aspects of international policy. Or then think about the interplay of these concerns with intergenerational ones.

I think that if we look at the world as a whole over the past 30 years, we see a clear reduction in inequality of living standards thanks to economic growth in China and India and increased political liberty in Latin America and Eastern Europe. The big dark cloud is that we also see a frightening—and growing—risk of environmental disaster.

A Free Market in Legal Services

MB writes in to ask what I think of bar exams, and the answer is: not much. More generally, I think we ought to have a much freer market in legal services. As Dean Baker memorably put it “The ‘free-trade’ crew want to have a single set of standards for all forms of merchandise traded all over the world, but it has apparently escaped their attention that a lawyer from New York can’t practice across the river in New Jersey.”

It hasn’t escaped my attention! I just think we shouldn’t cling to this as a hypocrisy talking point. If someone in New Jersey wants to hire a New York lawyer to represent him in some matter, that should be between them. If a bunch of New Jersey lawyers want to form a membership organization called the New Jersey Bar Association and give people a test that you need to pass in order to call yourself a New Jersey Bar Association Certified Lawyer more power to them. But for them to get the project off the ground, they’d have to do something to turn the test into some kind of reliable indicator of quality. If you look at actual behavior of law firms, they don’t seem to indicate current bar exams in this light—you don’t need to pass the bar to get hired by a major firm out of law school. Similarly, I get that New Jersey and New York have different laws. But New York has different laws in 2010 than it had in 1990 and yet there’s no requirement that you need to retake the bar exam to check if you’ve been up to speed.

In general the failure to re-test incumbents is a good sign point that you’re looking at an arbitrary barrier to entry rather than a real indicator of quality. I’m not sure how big a deal this particular brand of licensing abuse actually is since I don’t get the sense that inadequate supply of lawyers is driving any particularly pressing social problems. A lot of lower-end legal services does, however, seem like it would be amenable to outsourcing to foreign clerical workers and I understand that there’s already a trend in this direction.

Stuck In Zero

André Meier at the IMF has a working paper (PDF) called “Still Minding the Gap—Inflation Dynamics during Episodes of Persistent Large Output Gaps” that examines what happens to prices during big recessions. Gavyn Davies offers a summary:

As the standard theory would predict, inflation fell in virtually all of these episodes. Interestingly, Meier finds that the extent of the decline in inflation is proportional to the rate of inflation in the year before the deep recession starts. This implies that countries which start out with a very high rate of inflation (e.g. the UK from 1980-83) see the biggest drop in inflation when a deep recession occurs. As a rough rule of thumb, the inflation rate seems to drop by about one fifth of the original rate for every year that the episode lasts, with much of the improvement coming in the first couple of years.

Since many developed economies, including the US, embarked on their present deep recessions with inflation at around 2-2.5 per cent, this rule of thumb would indicate that inflation should be dropping at about 0.5 per cent per annum, which is almost exactly what has been happening. So far, then, so bad.

But the really interesting thing is that this rate of decline in inflation appears to peter out altogether as inflation itself approaches zero. Admittedly, there are only two such episodes in the database – Japan in 2001-03 and Sweden in 1992-94. But they are nonetheless important, because we do not have much else to cling on to. These episodes of downward rigidity in inflation are probably explained by the fact that price and wage setters are extremely reluctant actually to cut prices or nominal wages in absolute terms, so a really massive shock (perhaps even bigger than the recent credit crunch) is needed to force the overall inflation rate below zero.

So probably not actual deflation, instead inflation rates stuck at around zero because “[t]here will be times when higher commodity prices, or declining exchange rates, will lead to temporary increases in inflation, counter to the dominant deflationary trend.” A huge negative shock—like a major Iran-related disruption in energy supplies—would change that, but mostly things will be flat. Davies observes that “in this netherland of zero inflation, many of the adverse dynamics of debt deflation (identified by Irving Fisher in the 1930s) will be working away, insidiously, under the surface.”

I would only add that if this comes to pass it will be more a political problem than an economic one. Central bankers may simply redefine their mission as “avoiding deflation” and congratulate themselves if the price level goes up 0-1 most quarters, while falling occasionally in response to negative shocks. They’ll chalk the resulting high unemployment up to “structural factors” and business groups and rich people will insist that only unpopular right-wing ideas can ameliorate the structural issues that are forcing unemployment up. The two percent inflation of the 1990s and 2000s will be redefined as “too high” just as today we’ve redefined the fine-at-the-time four percent inflation of the 1980s as “too high.”

The Higher Ed Racket

The Obama administration’s view on how to expand access to higher education in the United States is pretty simple, provide more money but demand more accountability. Funds spent helping young people learn valuable skills are money well-spent, but funds spent on pointless churning are pure waste. Alec MacGillis has a great piece in the Post about how this plays out, including a revealing quote:

“Higher education is an interest group like any other, and what it wants is a lot of money from the taxpayer and no oversight of how that money is spent,” said Kevin Carey of the think tank Education Sector. “And they’ve been very successful getting it for a long time.”

Sarah Flanagan, a lobbyist for the National Association of Independent Colleges and Universities (NAICU), said the provisions crossed the line. They “put out national incentives and fund states and get states to get colleges to increase performance. That’s not how colleges operate,” she said.

And it’s true, that’s not how they operate and that’s the problem. I would add special kudos to the Post for running this piece because, as MacGillis notes at the end, one company that really, really, really, really doesn’t like the administration’s effort to not let poor-performing for-profit colleges soak up endless quantities of taxpayer cash is the Washington Post Company, whose Kaplan University group is among the worst-performing major players in the field.

Obama’s Porkilicious Taqiyya

Obama at Ben's Chili Bowl with DC Mayor Adrian Fenty

Steve M at No More Mr Nice Blog falls for the White House spin hook, line, and sinker:

Anyone remember when candidate Barack Obama was getting grief for going to Philadelphia and sampling expensive Spanish ham? Doesn’t sound like something a secret Muslim would eat — nor is the honey-baked ham the Obamas served along with the turkey last Thanksgiving. The half-smoke he got at Ben’s Chili Bowl a couple of weeks before Inauguration Day is a sausage that’s half-pork, half-beef. Oh, and the beer at that beer summit didn’t quite comport with the teachings of the Koran, did it? But all that was just weaving a web of deceit, right?

I’ll admit that for a long time my own views were along these lines. After all, the very first time I met State Senator (and US Senate candidate) Barack Obama we were at a hotel in Boston (I believe it was the Westin Copley Place) on line at a breakfast buffet fighting for the tongs to grab some bacon. But then I learned all about taqiyya which proves that counter-evidence to the “secret Muslim” thesis only demonstrates how far the conspiracy goes.

Lobbying and Policy Change

The current issue of Miller-McCune features a great Melinda Burns writeup of the moderately counterintuitive findings in the award-winning recent book Lobbying and Policy Change: Who Wins, Who Loses, and Why by Frank R. Baumgartner, Jeffrey M. Berry, Marie Hojnacki, David C. Kimball, and Beth L. Leech. I’m not 100 percent sure what the best way to characterize their findings is. I’ve heard it glossed as showing that lobbying “doesn’t matter” or doesn’t matter “as much as you think” but I’m not sure that’s quite right. I’d say it’s something more like “the policy agenda in Washington is dominated by issues that have substantial lobbies on both sides, and relative strength of the lobbies doesn’t determine the outcome; also the outcome is usually that nothing changes.”

Here’s how Burns puts it:

The real outcome of most lobbying — in fact, its greatest success — is the achievement of nothing, the maintenance of the status quo. “Sixty percent of the time, nothing happens,” says Frank Baumgartner, one author of the book and a political science professor at the University of North Carolina at Chapel Hill. “What we see is gridlock and successful stalemating of proposals, with occasional breakthroughs. We see a pattern of no change, no change and no change — and then some huge reform.”

But those large reforms — such as health care for 32 million uninsured Americans under President Barack Obama, the scheduled phase-out of the estate tax under President George W. Bush, and the normalization of trade relations with China under President Bill Clinton — are far more often linked to a change in who inhabits the White House than to campaign contributions or K Street hires.

On the one hand, this punctures some insidery illusions about change happening as a result of an awesome duel between skilled lobbyists and advocates with the better policy change ninja winning the day. At the same time, I think he does help explain the ways in which interest group strength do shape policy outcomes in decisive ways. It’s not possible to reform the health insurance system without arousing some powerful opposition. Consequently, to get it done it had to be done in such a way as to induce some other powerful lobbies—in the case of the Affordable Care Act, mostly pharmaceutical firms and labor unions—to line up in favor of change. But once you have strong lobbies on both sides, it’s not like you win by having more or better lobbyists: “across the board for the 98 issues, the side with more lobbyists, more PAC donations, bigger organizational budgets and more members won only half the time.”

There’s a lot you could say about this, but the main upshot is that reforms aimed at curbing the power of lobbyists or what have you seem to be somewhat barking up the wrong tree. More important than disempowering the most powerful actors is to find ways to try to empower the powerless. If you don’t have any lobbyists, donations, members, or organization at all then you’ve got a real problem. And the other is simply that the system’s overwhelming feature is its massive tilt toward the status quo—something I don’t like, that others do like, and that it might be possible to change.

Carbon Pricing is Not Primarily About Car Ownership

Ezra Klein posts this chart and observes that people are “overestimating the importance of appliances, and the centrality of cars doesn’t bode well for pricing carbon.”

This is a very widespread mistake. For reasons I don’t quite understand, but that I have possibly contributed to by writing lots of blog posts about walkable urbanism because I’m interested in it personally, people have gotten in it their heads that automobiles are the primary issue in carbon emissions. In reality, oil is not that carbon-intensive compared to coal-fired electricity and transportation is not that big a consumer of energy:

What’s more, a fair share of “transportation” is the transportation of goods rather than the transportation of people. If you look at per capita carbon emissions you’ll see that California is one of the very lowest-emission states in the union, notwithstanding its famous automobile orientation. That’s because mild weather plus relatively clean electricity equals low emissions. Heating and cooling poorly insulated single-family homes is extremely energy intensive. Indeed, in some ways the biggest contribution of walkable urbanism to low emissions is probably that urban homes tend to be smaller and multi-family homes are better insulated. What’s more, from a technical standpoint it’d be very straightforward for the current US vehicle fleet to become more fuel efficient, whereas it’s not at all straightforward to overhaul the whole electricity-generation system.

I think there are a lot of problems with the central role automobile ownership plays in American life, but it really shouldn’t be a major impediment to reasonable carbon pricing.
