Stiglitz vs Krugman

A very interesting front is opening up regarding the current state of America.

Some economists believe that the main problem in America is a lack of demand, defined as the desire to buy, the willingness to buy, and the ability to pay for it

From Paul Krugman:

There is nothing — nothing — in what we see suggesting that this current depression is more than a problem of inadequate demand. This could be turned around in months with the right policies. Our problem isn’t, ultimately, economic; it’s political, brought on by an elite that would rather cling to its prejudices than turn the nation around.

The implication here is that people just don’t have the money in their pockets to spend at the levels they were five years ago, and the solution is (through whatever means) giving them that money.

As well as the obvious (and accurate) Austrian retort that demand in 2006 was being pushed skyward as part of a ridiculous and entirely artificial debt-financed bubble, other economists believe that a lack of demand is just a symptom of other underlying symptoms. I myself believe that the three main problems are a lack of confidence stemming from high systemic residual debt, deindustrialisation in the name of globalisation (& its corollary, financialisation and that sprawling web of debt and counter-party risk), and fragility and side-effects (e.g. lost internal productivity due to role as world policeman) coming from America’s petroleum addiction.

Now Joe Stiglitz has weighed in in a lengthy and essential Vanity Fair piece:

The trauma we’re experiencing right now resembles the trauma we experienced 80 years ago, during the Great Depression, and it has been brought on by an analogous set of circumstances. Then, as now, we faced a breakdown of the banking system. But then, as now, the breakdown of the banking system was in part a consequence of deeper problems. Even if we correctly respond to the trauma—the failures of the financial sector—it will take a decade or more to achieve full recovery. Under the best of conditions, we will endure a Long Slump. If we respond incorrectly, as we have been, the Long Slump will last even longer, and the parallel with the Depression will take on a tragic new dimension.

Many have argued that the Depression was caused primarily by excessive tightening of the money supply on the part of the Federal Reserve Board. Ben Bernanke, a scholar of the Depression, has stated publicly that this was the lesson he took away, and the reason he opened the monetary spigots. He opened them very wide. Beginning in 2008, the balance sheet of the Fed doubled and then rose to three times its earlier level. Today it is $2.8 trillion. While the Fed, by doing this, may have succeeded in saving the banks, it didn’t succeed in saving the economy.

Reality has not only discredited the Fed but also raised questions about one of the conventional interpretations of the origins of the Depression. The argument has been made that the Fed caused the Depression by tightening money, and if only the Fed back then had increased the money supply—in other words, had done what the Fed has done today—a full-blown Depression would likely have been averted. In economics, it’s difficult to test hypotheses with controlled experiments of the kind the hard sciences can conduct. But the inability of the monetary expansion to counteract this current recession should forever lay to rest the idea that monetary policy was the prime culprit in the 1930s. The problem today, as it was then, is something else. The problem today is the so-called real economy. It’s a problem rooted in the kinds of jobs we have, the kind we need, and the kind we’re losing, and rooted as well in the kind of workers we want and the kind we don’t know what to do with. The real economy has been in a state of wrenching transition for decades, and its dislocations have never been squarely faced. A crisis of the real economy lies behind the Long Slump, just as it lay behind the Great Depression.

At the beginning of the Depression, more than a fifth of all Americans worked on farms. Between 1929 and 1932, these people saw their incomes cut by somewhere between one-third and two-thirds, compounding problems that farmers had faced for years. Agriculture had been a victim of its own success. In 1900, it took a large portion of the U.S. population to produce enough food for the country as a whole. Then came a revolution in agriculture that would gain pace throughout the century—better seeds, better fertilizer, better farming practices, along with widespread mechanization. Today, 2 percent of Americans produce more food than we can consume.

What this transition meant, however, is that jobs and livelihoods on the farm were being destroyed. Because of accelerating productivity, output was increasing faster than demand, and prices fell sharply. It was this, more than anything else, that led to rapidly declining incomes. Farmers then (like workers now) borrowed heavily to sustain living standards and production. Because neither the farmers nor their bankers anticipated the steepness of the price declines, a credit crunch quickly ensued. Farmers simply couldn’t pay back what they owed. The financial sector was swept into the vortex of declining farm incomes.

The cities weren’t spared—far from it. As rural incomes fell, farmers had less and less money to buy goods produced in factories. Manufacturers had to lay off workers, which further diminished demand for agricultural produce, driving down prices even more. Before long, this vicious circle affected the entire national economy.

The parallels between the story of the origin of the Great Depression and that of our Long Slump are strong. Back then we were moving from agriculture to manufacturing. Today we are moving from manufacturing to a service economy. The decline in manufacturing jobs has been dramatic—from about a third of the workforce 60 years ago to less than a tenth of it today. The pace has quickened markedly during the past decade. There are two reasons for the decline. One is greater productivity — the same dynamic that revolutionized agriculture and forced a majority of American farmers to look for work elsewhere. The other is globalization, which has sent millions of jobs overseas, to low-wage countries or those that have been investing more in infrastructure or technology. (As Greenwald has pointed out, most of the job loss in the 1990s was related to productivity increases, not to globalization.) Whatever the specific cause, the inevitable result is precisely the same as it was 80 years ago: a decline in income and jobs. The millions of jobless former factory workers once employed in cities such as Youngstown and Birmingham and Gary and Detroit are the modern-day equivalent of the Depression’s doomed farmers.

The consequences for consumer spending, and for the fundamental health of the economy — not to mention the appalling human cost—are obvious, though we were able to ignore them for a while. For a time, the bubbles in the housing and lending markets concealed the problem by creating artificial demand, which in turn created jobs in the financial sector and in construction and elsewhere. The bubble even made workers forget that their incomes were declining. They savored the possibility of wealth beyond their dreams, as the value of their houses soared and the value of their pensions, invested in the stock market, seemed to be doing likewise. But the jobs were temporary, fueled on vapor.

So far, so excellent. Stiglitz first shovels shit over the view of Fisherian debt-deflation as the main cause of the slump in demand — debt-deflation is a symptom, and a very nasty one, but not really a cause. Second, Stiglitz also correctly notes that today’s ailments are the result of social, infrastructural and productive upheaval in the real economy. He correctly identifies the leading trend here — manufacturing (and, it should be added, primary industry) has been ripped out of America by the forces of globalisation, and the powerful pull of cheaper wages. This is a strong explanation of why Krugman’s view — that the only thing missing is demand, and that government can fix that in an instant — is nonsense.

As I wrote earlier this month:

The point here is that economic health — and real industrial output, measured in joules, or in “needs met” — and money circulation are in reality almost totally decoupled. Getting out of a depression requires debt erasure, and new organic activity, and there is absolutely no guarantee that monetary easing will do the trick on either count. Most often, depressions and liquidity traps are a reflection of underlying structural and sociological problems, and broken economic and trade systems. Easing kicks the can down the road a little, and gives some time and breathing room for those problems to be fixed, but very often that just doesn’t happen. Ultimately, societies only take the steps necessary (e.g. a debt jubilee) when their very existence seems threatened.

Stiglitz continues:

What we need to do instead is embark on a massive investment program—as we did, virtually by accident, 80 years ago—that will increase our productivity for years to come, and will also increase employment now. This public investment, and the resultant restoration in G.D.P., increases the returns to private investment. Public investments could be directed at improving the quality of life and real productivity—unlike the private-sector investments in financial innovations, which turned out to be more akin to financial weapons of mass destruction.

Now, I don’t really have a problem with the idea that government can do some good. If people in a democracy choose to solve problems via public spending, well, that’s part of the bargain in a democratic state. Even Adam Smith noted that government should fund “certain great institutions” beyond the reach of private enterprise.

But here we reach the great problem with Stiglitz’s view:

The private sector by itself won’t, and can’t, undertake structural transformation of the magnitude needed—even if the Fed were to keep interest rates at zero for years to come. The only way it will happen is through a government stimulus designed not to preserve the old economy but to focus instead on creating a new one. We have to transition out of manufacturing and into services that people want — into productive activities that increase living standards, not those that increase risk and inequality.

The United States spent the last decade (arguably longer) and trillions of dollars embroiled in wars aimed at keeping oil cheap, and maintaining the flow of global goods precisely because America is dependent upon those things. America does not play global policeman out of nicety or vanity — she does it out of economic necessity. That is precisely because America let globalisation take away all of her industry, making her dependent not only on the continued value of her paper dollar, but on the flow of global trade in energy and goods.

Investing more money in services will leave America dependent on these contingencies. And dependency is fragility — and the more fragile America becomes, the more aggressive she becomes in maintaining and controlling the flow of global goods.

Any stimulus package ought to instead be focussed on making America energy independent, and encouraging innovative new forms of manufacturing (e.g. 3-D printing) that can undercut Chinese labour.

So while Stiglitz must be commended for seeing through the haze, it is rather puzzling that his alternative is services, rather than self-sufficiency.

While America is dependent on foreign goods and energy, she is prone to not only waste huge amounts of productive capital on war and weapons, but she also risks serious economic damage from events such as oil shocks, geopolitical shocks, regional wars, and — well — anything that might slow down or endanger global trade. Her need to police the world makes her even hungrier for oil, which means she spends more money on the world, which makes her hungrier for oil.
