Should the Fed risk inflation to spur growth?

The New York Times asked me and two others this question for its “Room for Debate” blog. My answer follows. Not news for readers of this blog, but maybe a fun concise summary

Should the Fed risk inflation to spur growth? The Fed is already trying as hard as it can to spur growth, and to create some inflation. The Fed has created about two trillion dollars of money, set interest rates to zero, and promised to keep them there for years. It has bought hundreds of billions of long-term government bonds and mortgages in order to drive those rates down to levels not seen in a half a century.


The fact is, the Fed is basically powerless to create more inflation right now – or to do anything about growth. Interest rates can’t go below zero, and buying one kind of bond while selling another has minuscule effects. Which is just as well. While preventing deflation in the recession was vital – and the Fed did it – the idea that a deliberate inflation is the key out of our policy-induced doldrums makes no sense.

 Tight monetary policy is not the source of our problems. Monetary policy is loose by any measure. Anti-growth policies are our problem. Our economy is being stifled by over-regulation, chaotic taxes and policy uncertainty. You make money now by lobbying regulators for special treatment, not by starting companies. We fix that with growth-oriented policies that remove the source of the problem.

Inflation remains a danger, but not so much because of what the Fed is doing. U.S. debt is skyrocketing, with no visible plan to pay it back. For the moment, foreigners are still buying prodigious amounts of that debt. But they are mostly buying out of fear that their governments are worse. They are short-term investors, waiting out the storm, not long-term investors confident that the US will pay back its debts. If their fear passes, or they decide some other haven is safer, watch out. The inflation some are hoping for will then come with a vengeance. It’s not happening yet: Interest rates are low now. But so were mortgage-backed security rates and Greek government debt rates just a few years ago. And inflation need not happen, if we put our fiscal house in order first. But if it happens, it will happen with little warning, the Fed will be powerless to stop it, and it will bring stagnation rather than prosperity.

Followup thought (more on the last paragraph):

Yes, interest rates are low, and there is little sign of inflation. I hate to use the word “bubble,” but US government debt strikes me as a “bubble,” meaning “whatever it is you thought was going on with houses, mortgage backed securities and Greek government debt in 2006, or internet stocks in 1998,  and used the word "bubble” to describe, is going on with US government debt now.“

More precisely, an asset can have a high value (government bond prices are high, interest rates are low) because people think its "fundamental” cashflows are high, or because people are willing to hold the asset for a year or two, and they think they can get out and sell it before its value falls.

It’s hard to make a story that US long term debt has a high price (low interest rate) because investors are really impressed with the huge budget surpluses in a credible long-term US fiscal commitment. (!) If you don’t buy that story, then the admittedly huge demand for US debt is must be a short-term demand, a low required return, a “flight to quality” that can easily evaporate. It can also easily increase for a few years before it evaporates. Europe does seem to be going down the tubes.

It has to be one or the other though. People (you know who) who say “interest rates are low, inflation is low, the government can borrow huge amounts and blow it on preparations for an alien invasion, don’t worry, it’s not a bubble, it can’t burst” have to assume that markets really trust the government to pay back those debts.

Bloomberg TV Interview

An interview on the Tom Keene’s show this morning on Bloomberg TV


I always feel bad after these things, that I could have answered much better or clearer. Or found a better tie. Well, we do what we can. A direct link

Just how bad is the economy?

The second-quarter GDP numbers came out. The newspapers and Republicans pounced on low growth and anemic job growth. The Democrats rebut growth is growth and tell us of the steady job gains. How bad is the economy?

Economists know that levels matter, and that long-run growth matters more than anything else. I made a few graphs to emphasize these points.

Start with the level (in logs) of real GDP. (This is an update of a graph I saw on John Taylor’s blog.)

Looking at levels you see the current awfulness better than by looking at growth rates. GDP declined almost 5% in the recession, but then started growing at a glacial pace, averaging 2.4% since the trough.  We seem stuck in this slow growth trap.


If you distrust trend lines, you are wise. But this one reflects a solid historical pattern. Here is real GDP and the 1965-2007 trend through postwar history.

You can see that the economy has quite reliably returned to the trend line after recessions.The 1950s had a steeper trend, but there too the small recessions were followed by catchup growth.

Here is what the recovery is supposed to look like (Again, idea stolen from John Taylor, except I’m using trends rather than “potential GDP” which I distrust.) 

To be fair, I fit the trend through 1980, so I would not use ex-post information. You see that after the severe 1980 recession at the even more severe 1982 recession, the economy recovered to trend, by posting a few years of 6% growth.

The tragedy is poorly expressed in growth rates. By 1987, the economy was back on the prior trend line. We are now 14.5% below the trendline, and each year that goes by like this we lose another half a percent. The average person in the economy is producing 14.5% less, and earning 14.5% less, than if we had followed the path following the 1982 recession.

That’s a lot – and a lot more than the litany of quarterly growth rates suggest.

I used trends, rather than the CBO potential output. If you read how they make it, you’re likely to do that too. But here is the same graph contrasting my trend and the CBO’s potential

This is tragic. The CBO is giving up on us. The CBO potential, which goes towards a 2.35% long run growth rate, says that what we are seeing now is the new normal. All we can hope for is a modest recovery, and then anemic, sclerotic growth forever after that. The difference between 2.3% and 3.0% adds up fast as the years go by. (And the CBO has been bending the trend line down steadily as the recession goes on. Back in 2005, it’s “potential” looked like my “trend.” They didn’t see a permanent downward shift in level or reduction in growth rates. Look for “potential” to keep declining.)

Well, perhaps the CBO is doing its job as forecasters, saying “here is what will happen if you continue down the present policy path,” not “here is where the economy would be if you adopted growth-oriented policies.”

What about employment? I find employment more significant than unemployment. Unemployment means job search. It means people answer a survey saying they don’t have a job, and are actively searching for a job. It does not count all the people who gave up, or went on disability (effectively ending their careers), early retirement, or are just living in Mom’s basement and playing video games. (I don’t mean to make light of it. That may be the most tragic, as the chance to accumulate skills is lost.)

Here’s a good summary measure, the ratio of employed people to the population

This is really tragic. Employment declined by about 7 million people, from 63% of the population to about 58%. And it has stayed there ever since. The “job gains” you hear about in the news are just barely keeping up with population. As we are about 14% below trend and slowly losing ground, we are 7 million jobs short and sitting there too.

The link between employment and output is productivity. To keep the numbers simple here, I made plots of output per worker. Output per hour, and corrections for demographics and capital use are better, but this is simpler and works about as well. Here is a graph of productivity.

I crammed a lot of information in this graph. The first thing to notice is the behavior in the recession and now. There was a dip in productivity – output fell more than the number of workers fell. But it has since recovered.

In the short run, capital doesn’t change much, so as a rough guide you make more output when you hire more workers (or increase hours) and vice versa. So, GDP = Productivity x workers. To get more workers, we need to make a lot more GDP. The lackluster GDP growth is the other side of the terrible employment coin.

There’s more in the graph. In the long run, rising productivity is behind everything good in the economy. It’s what gives more income per capita. Rising productivity is the only hope for paying for entitlements and getting out of our deficit trap. It’s the main hope for long-run GDP growth, after the empolyment-population ratio reverts to where it should be. Rising productivity comes from new ideas, new companies, new ways of doing business. It isn’t all pleasant. Lots of incumbents lose out. Rising productivity is the core of a “growth” agenda as economists understand the word. 

You see in the graph that something terrible happened in the 1970s. Productivity, which was behind the large postwar boom, slowed down to a glacial 1% per year. 1982 marked a break in that as well. Productivity  started growing 1.69% per year, producing the boom of the late 1980s and 1990s, and incidentally producing large Federal surpluses.

OK, but the far right of the graph doesn’t look so good does it. Here it is, blown up, with a 2003-today trend marked in as well.

This is an economists’ horror movie. Yes, productivity did rebound. But it seems to be growing slowly as well.

The trends are an economists’ horror movie. Real GDP seems not to be recovering at all – no period of swift growth to go back to a trend. We seem stuck at 2.4% growth forever. The CBO is giving up on us too. Employment will not recover as a fraction of population until the economy recovers. We seem stuck at low employment forever. And now we seem headed to a 1970s productivity slowdown as well.

I don’t view this as contentious, outside of Presidential politics. Paul Krugman thinks the economy is pretty awful too.

What to do? If only it were so simple as to have the Fed print up another two trillion dollars, or have the Treasury borrow another $5 trillion and blow it on stimulus boondoggles. We’re stuck in sclerotic growth, and to everyone but a few die-hard extremists, that means growth-oriented policies are the only way out. 


Disclaimer. Yes, I know there are better ways to measure all this, especially productivity. This is an attempt to paint the basic picture using the simplest numbers. The message is, look at the levels and look at the trends. If you do that with better data, you will have gotten the message.

Data are from the St. Louis Fed’s wonderful Fred database, series GDPC96, GDPPOT,  EMRATIO.

A good Greek story

Matt Jacobs sent along a link to a great story from Greece on Reuters,  “Lessons in a shrimp farm’s travails.” The whole article is worth reading, but here are a few tidbits:

Just over a decade ago, Napoleon Tsanis set out from Sydney with 11 million euros and a dream to build a shrimp farm in his ancestral homeland… What he got was years of wrestling Greek bureaucracy and a court battle with a civil servant…

it’s the civil servants that are throwing you into this labyrinth on purpose,“ Tsanis, 44, said. "The law gives them the latitude to delay you or punish you.”

…A process that would take just two or three months to complete in Australia got stuck in a maze of official opinions and permits across several ministries. Greek politicians assured him that the paperwork would be done in 18 months, but that date came and went with no progress.

… then, though, another law change that sought to keep aquaculture projects small meant Tsanis had to break up his farm into sections to go ahead.

…One of the main obstacles to more investment is the legal jumble that dictates how Greek businesses work. Even government officials admit the lack of clear laws and the endless requests for opinions, studies and permits are there to give work to unionized specialists.

“There are whole businesses and technical offices employing engineers and experts specifically for the purpose of licensing,” said Tsakanikas at the IOBE think tank.

Red tape often leads to corruption.

Tsanis said he steadfastly refused to bribe anyone. In one incident, in 2005, he appealed to a minister in Athens to get a permit unstuck. “The minister called in the public servant who was refusing to give us the permit and ordered him to issue it the next morning,” he said, declining to specify the minister or ministry involved. “When we went back to get it, the civil servant told me: ‘Australian, that guy is a politician and he’ll be gone tomorrow, but I’ll be here waiting for you.

The only European Union country not to have a fully functioning land registry - despite collecting EU funds to set it up and then paying penalties when it failed to do so - Greece still lacks a comprehensive zoning law and building rules.

"Several interests prefer a fuzzy system they can manipulate,” Papaconstantinou said. “We must simplify building permits, which are a hub of corruption.”

After his shrimp farm opened, Tsanis had hoped to build a 120 million euro golf resort. But when the local authorities decided they didn’t want it, he opted not to fight.

This story rings with several of the themes on this blog, and I can’t resist hitting you over the head a bit.

The nature of “regulation.” In the popular discussion “regulation” means a wise system of rules that keep order in markets. Here is regulation in action.

There are different kinds of regulation. This is “regulation” by a deliberately vague forest of laws and rules, which give great discretionary power to the functionaries who administer those regulations. And clearly, they and their cronies like to keep it that way.

This is not “regulation” by clear rules, which you can quickly appeal in court if they are misapplied. The lack of title, zoning, and property rights falls in the same bucket.



Let us not feel superior, fellow Americans. This is the system of regulation to which we are crashing. Dodd Frank and Obamacare look a lot like Greek zoning laws, as far as the power of appointed officials vs. the rule of law are concerned.


Currency. Many of my macroeconomics colleagues think the main problem with the Greek economy is an “overvalued” exchange rate and thus too high wages. Rather than see high unemployment drive down wages that are “sticky” by some magic mechanism (even Paul Krugman admits he doesn’t really know why wages are “sticky”), they would like to see Greece have a Drachma to devalue, or what the heck, devalue the whole euorozone, as even Anil Kashyap and Martin Feldstein have recently argued, along with Austan Goolsbee and more reliable liberals.

How much of Mr. Tsanis’ troubles does this analysis describe? Not zero, in fact. The article says

He survived, he said, thanks to the 30 percent appreciation of the Australian dollar versus the euro in recent years

He doesn’t even mention wages. I guess you have to open a factory before you have to start paying people.

You assign a percentage. Add up whether, faced with this story, the first thing you want to do is devalue the currency, or maybe if as economists we should be writing opeds about “shock liberalization” instead. Decide if this economy will liberalize on its own, given time, and “breathing space” by more German subsidies.

Micro vs. macro. In Greece’s slump, as in ours, how much is this, “microeconomic” problems solveable only by micro liberalization, and how much is “macroeconomic,” solveable by central banks, “stimulus” programs and the like?

Who is for growth?

This weekend, a prominent columnist delivered some brilliant advice to a presidential candidate:

…make America the launching pad where everyone everywhere should want to come to launch their own moon shot, their own start-up, their own social movement. We can’t stimulate or tax-cut our way to growth. We have to invent our way there….

…we should aspire to be the world’s best launching pad because our work force is so productive; our markets the freest and most trusted; our infrastructure and Internet bandwidth the most advanced; our openness to foreign talent second to none; our funding for basic research the most generous; our rule of law, patent protection and investment-friendly tax code the envy of the world; our education system unrivaled; our currency and interest rates the most stable; our environment the most pristine; our health care system the most efficient; and our energy supplies the most secure, clean and cost-effective.

No, we are not all those things today…

Ok, quiz time. Is this

1. Some zany free-marketer pushing the Romney campaign to give some teeth to its “pro-growth” rhetoric?
2.  Advice to Ron Paul on a speech to rouse the Republican convention?
3. Thomas Friedman, New York Times columnist extraordinaire, in its Sunday pages advising the Obama campaign?

 Amazingly, C. The preamble was

Is there an integrated set of policies, and a narrative, that could animate, inspire and tie together an Obama second term? I think there is…. Obama should aspire to make America the launching pad..

Which gives me hope. Friedman is obviously much better connected than I. If he thinks there is even a ghost of a chance that the Obama campaign would adopt such a strategy, or that the administration would follow anything vaguely like this policy, that is tremendously good news. I thought these sorts of positions, while  middle-of-the-road growth economics, were, in the political sphere, too wildly free-market to hope for from the Romney campaign.

Think of what they mean.

• “We can’t stimulate our way to growth” is a remarkable admission for anyone in the New York Times orbit. Ok, it included “or tax cut,” but an “investment-friendly tax code” has to mean low marginal rates on investment, which means low marginal rates on investment income. No way around it, lower marginal rates, broaden the base.
• “Our currency and interest rates the most stable” means likewise abandoning hope that endless rounds of Fed “stimulus” or devaluation as the key to success. Both statements are a repudiation of discretionary shoot-from-the-hip macroeconomic policy.
• A “productive” work force is not composed of protected unions and government workers, on federal boondoggle contracts.  
• “Openness to foreign talent” means we have to let people in. 
• “Rule of law” means that health, energy and financial regulation cannot be run by powerful regulators and their crony-capitalist protected industries.
• All of Friedman’s startups succeed by undercutting and putting out of business old ossified but politically well connected companies, yes creating net new jobs but destroying a lot of old ones in the process. 
• If you’ve been reading this blog at all, you know  the likelihood that the current health care law and expansion of medicare will deliver anything like “efficiency.”

These are radical views indeed. Congratulations to Friedman for stating them, and I hope his friends at the campaign are listening. A Nixon-to-China moment would certainly be refreshing.

(OK, but the moon shot analogy is just weird. What does spending about 3 percent of GDP to send two guys to the moon have to do with unleashing the innovation of thousands of new entrepreneurs? )

Sand in the gears

Today’s Wall Street Journal has a beautifully informative editorial, “Employment, Italian Style.” Snippets:

Once you hire employee 11, you must submit an annual self-assessment to the national authorities outlining every possible health and safety hazard to which your employees might be subject. These include stress that is work-related or caused by age, gender and racial differences. You must also note all precautionary and individual measures to prevent risks, procedures to carry them out, the names of employees in charge of safety, as well as the physician whose presence is required for the assessment.


Once you hire your 16th employee, national unions can set up shop. As your company grows, so does the number of required employee representatives, each of whom is entitled to eight hours of paid leave monthly to fulfill union or works-council duties. Management must consult these worker reps on everything from gender equality to the introduction of new technology

Hire No. 16 also means that your next recruit must qualify as disabled. By the time your firm hires its 51st worker, 7% of the payroll must be handicapped in some way,…

Once you hire your 101st employee, you must submit a report every two years on the gender dynamics within the company. This must include a tabulation of the men and women employed in each production unit, their functions and level within the company, details of compensation and benefits, and dates and reasons for recruitments, promotions and transfers, as well as the estimated revenue impact….

This kind of thing is hard to track down. You can’t easily find a prepackaged “list of regulatory sand in the gears lowering productivity and employment in Italy,” the way we can find (statutory) tax rates, spending numbers, interest rates, and so on.  So like the drunk in the old joke, looking for his car keys under the light even though he knows he dropped them a block a way, much economic discussion focuses on those headline issues (“Stimulus!” “Austerity!” “Bailout!” “Leave the Euro!” “Raise/lower taxes!”) and ignores all the sand in the gears.

The journal writes, 

All of these protections and assurances, along with the bureaucracies that oversee them, subtract 47.6% from the average Italian wage, according to the OECD.

I wish the WSJ had footnotes or links, even in its online edition, to make it easier to track down  numbers of this sort. A quick tour through the OECD website provides some horrifying numbers on
 Labor tax wedges of 40-50%, to which we must add “non-tax compulsory payments (NTCPs)” which “represent a strong increase over and above the overall tax burden. E.g., in 2011, the compulsory payment wedge for the average single worker was 50.4% compared with the corresponding tax wedge of 47.6%” And remember, once they give you a euro, you still pay another 21% VAT before you can eat that plate of delicious pasta.  But the WSJ paragraph suggests 47.6% is the effective wedge of regulation on top of explicit taxation. (If readers know where it came from, add a comment.)

Also left out is the effect of this kind of hyper-regulation on corruption. You can imagine when the inspector comes in to see if all the paperwork is up to date how the conversation evolves. (Ask Luigi Zingales)

Cleaning up this mess is what we mean by “structural reform.” How to achieve it politically seems like a nightmare to me.  Fighting each of ten thousand regulations one by one seems hopeless. Each one sounds good, each one taken alone seems minor, each one has an entrenched interest backing it and an army of bureaucrats whose jobs depend on its enforcement. And the economy dies the death of a thousand cuts. Can you really abolish it all in one fell swoop or grand bargain?

Certainly not if you don’t try. 

The WSJ headline was

Prime Minister Mario Monti has issued a new “growth decree” to revive Italy’s moribund economy. Among other initiatives, the 185-page plan proposes discount loans for corporate R&D, tax credits for businesses that hire employees with advanced degrees,.. 

Not to belabor the obvious, but this is incredibly depressing. More special programs are not what Italy needs. I hope there are better ideas in the rest of the 185 pages.
