The Prophet in the Wilderness

Economics like most professions enjoys its prestige and doesn't want to "rock the boat" by asking hard questions about its own underpinnings. Hyman Minsky was cut from different cloth.

Here are some key bits from an excellent article in the Boston Globe by Stephen Mihm entitled "Why Capitalism Fails" that explores the ideas of Hyman Minsky:
Since the global financial system started unraveling in dramatic fashion two years ago, distinguished economists have suffered a crisis of their own. Ivy League professors who had trumpeted the dawn of a new era of stability have scrambled to explain how, exactly, the worst financial crisis since the Great Depression had ambushed their entire profession.

Amid the hand-wringing and the self-flagellation, a few more cerebral commentators started to speak about the arrival of a “Minsky moment,” and a growing number of insiders began to warn of a coming “Minsky meltdown.”

“Minsky” was shorthand for Hyman Minsky, a hitherto obscure macroeconomist who died over a decade ago. Many economists had never heard of him when the crisis struck, and he remains a shadowy figure in the profession. But lately he has begun emerging as perhaps the most prescient big-picture thinker about what, exactly, we are going through. A contrarian amid the conformity of postwar America, an expert in the then-unfashionable subfields of finance and crisis, Minsky was one economist who saw what was coming. He predicted, decades ago, almost exactly the kind of meltdown that recently hammered the global economy.

...

But if Minsky was as right as he seems to have been, the news is not exactly encouraging. He believed in capitalism, but also believed it had almost a genetic weakness. Modern finance, he argued, was far from the stabilizing force that mainstream economics portrayed: rather, it was a system that created the illusion of stability while simultaneously creating the conditions for an inevitable and dramatic collapse.

In other words, the one person who foresaw the crisis also believed that our whole financial system contains the seeds of its own destruction. “Instability,” he wrote, “is an inherent and inescapable flaw of capitalism.”

Minsky’s vision might have been dark, but he was not a fatalist; he believed it was possible to craft policies that could blunt the collateral damage caused by financial crises. But with a growing number of economists eager to declare the recession over, and the crisis itself apparently behind us, these policies may prove as discomforting as the theories that prompted them in the first place. Indeed, as economists re-embrace Minsky’s prophetic insights, it is far from clear that they’re ready to reckon with the full implications of what he saw.

...

That orthodoxy, born in the years after World War II, was known as the neoclassical synthesis. The older belief in a self-regulating, self-stabilizing free market had selectively absorbed a few insights from John Maynard Keynes, the great economist of the 1930s who wrote extensively of the ways that capitalism might fail to maintain full employment. Most economists still believed that free-market capitalism was a fundamentally stable basis for an economy, though thanks to Keynes, some now acknowledged that government might under certain circumstances play a role in keeping the economy - and employment - on an even keel.

Economists like Paul Samuelson became the public face of the new establishment; he and others at a handful of top universities became deeply influential in Washington. In theory, Minsky could have been an academic star in this new establishment: Like Samuelson, he earned his doctorate in economics at Harvard University, where he studied with legendary Austrian economist Joseph Schumpeter, as well as future Nobel laureate Wassily Leontief.

But Minsky was cut from different cloth than many of the other big names. The descendent of immigrants from Minsk, in modern-day Belarus, Minsky was a red-diaper baby, the son of Menshevik socialists. While most economists spent the 1950s and 1960s toiling over mathematical models, Minsky pursued research on poverty, hardly the hottest subfield of economics. With long, wild, white hair, Minsky was closer to the counterculture than to mainstream economics. He was, recalls the economist L. Randall Wray, a former student, a “character.”

...

Instead, Minsky drew his own, far darker, lessons from Keynes’s landmark writings, which dealt not only with the problem of unemployment, but with money and banking. Although Keynes had never stated this explicitly, Minsky argued that Keynes’s collective work amounted to a powerful argument that capitalism was by its very nature unstable and prone to collapse. Far from trending toward some magical state of equilibrium, capitalism would inevitably do the opposite. It would lurch over a cliff.

...

Minsky called his idea the “Financial Instability Hypothesis.” In the wake of a depression, he noted, financial institutions are extraordinarily conservative, as are businesses. With the borrowers and the lenders who fuel the economy all steering clear of high-risk deals, things go smoothly: loans are almost always paid on time, businesses generally succeed, and everyone does well. That success, however, inevitably encourages borrowers and lenders to take on more risk in the reasonable hope of making more money. As Minsky observed, “Success breeds a disregard of the possibility of failure.”

As people forget that failure is a possibility, a “euphoric economy” eventually develops, fueled by the rise of far riskier borrowers - what he called speculative borrowers, those whose income would cover interest payments but not the principal; and those he called “Ponzi borrowers,” those whose income could cover neither, and could only pay their bills by borrowing still further. As these latter categories grew, the overall economy would shift from a conservative but profitable environment to a much more freewheeling system dominated by players whose survival depended not on sound business plans, but on borrowed money and freely available credit.

Once that kind of economy had developed, any panic could wreck the market. The failure of a single firm, for example, or the revelation of a staggering fraud could trigger fear and a sudden, economy-wide attempt to shed debt. This watershed moment - what was later dubbed the “Minsky moment” - would create an environment deeply inhospitable to all borrowers. The speculators and Ponzi borrowers would collapse first, as they lost access to the credit they needed to survive. Even the more stable players might find themselves unable to pay their debt without selling off assets; their forced sales would send asset prices spiraling downward, and inevitably, the entire rickety financial edifice would start to collapse. Businesses would falter, and the crisis would spill over to the “real” economy that depended on the now-collapsing financial system.

...

By the end of the 20th century, the financial system that Minsky had warned about had materialized, complete with speculative borrowers, Ponzi borrowers, and precious few of the conservative borrowers who were the bedrock of a truly stable economy. Over decades, we really had forgotten the meaning of risk. When storied financial firms started to fall, sending shockwaves through the “real” economy, his predictions started to look a lot like a road map.

“This wasn’t a Minsky moment,” explains Randall Wray. “It was a Minsky half-century.”

Minsky is now all the rage.

...

To prevent the Minsky moment from becoming a national calamity, part of his solution (which was shared with other economists) was to have the Federal Reserve - what he liked to call the “Big Bank” - step into the breach and act as a lender of last resort to firms under siege. By throwing lines of liquidity to foundering firms, the Federal Reserve could break the cycle and stabilize the financial system. It failed to do so during the Great Depression, when it stood by and let a banking crisis spiral out of control. This time, under the leadership of Ben Bernanke - like Minsky, a scholar of the Depression - it took a very different approach, becoming a lender of last resort to everything from hedge funds to investment banks to money market funds.

Minsky’s other solution, however, was considerably more radical and less palatable politically. The preferred mainstream tactic for pulling the economy out of a crisis was - and is - based on the Keynesian notion of “priming the pump” by sending money that will employ lots of high-skilled, unionized labor - by building a new high-speed train line, for example.
You would be well served to go read the whole article.

The Federal Reserve did the right thing this time (unlike in the 1930s). As for the second prong of Minsky's solution, the stimulus spending on "shovel ready" projects was the answer. But sadly Obama got talked into a smaller stimulus than was needed (by a factor of at least 2!) and of the that money only one-third is being spent as Minsky suggested. Instead one-third was given away as tax cuts and one-third was given to state governments. So the lessons that Minsky developed were only partially applied to this crisis. The result will be a longer, slower recovery than it needed to have been.
