Paul Krugman has recently been critical of Friedman (and Phelps), the Phillips curve, and the Natural Unemployment Rate (NUR) theory in the process of arguing that due to the recent Great Recession, the accompanying financial crisis, and Bush-Obama-Fed Great Stagnation, Friedman has vanished from the policy front. Krugman makes this claim despite the fact there is an on-going vigorous debate on rules versus discretion with at least some attention to Friedman’s plucking model. While maligning Friedman’s contributions, Krugman manages a slap at Austrians and claims a renewed practical relevance for Keynes:

What I think is really interesting is the way Friedman has virtually vanished from policy discourse. Keynes is very much back, even if that fact drives some economists crazy; Hayek is back in some sense, even if one has the suspicion that many self-proclaimed Austrians bring little to the table but the notion that fiat money is the root of all evil — a deeply anti-Friedmanian position. But Friedman is pretty much absent.

The Friedman-Phelps hypothesis was the heart of the policy effectiveness debate of the 1970s and early 80s. The empirical evidence developed during the debate over the policy implications of the NUR model, at least temporally, discredited active Keynesian discretionary policy as an effective tool to reduce unemployment in the long run. One result of the debate: monetary policy appeared to improve, especially compared to the Fed’s dismal record in the late 1920s and 1930s and the mid 1960s to the late 1970s. Central banks, à la Friedman, focused on rules-based policy and inflation targeting resulting in what many, following John B. Taylor, call the Great Moderation of the early 1980s to the early 2000s.

Krugman does recognize the “stagflation (of the 1970s) led to a major rethinking of macroeconomics, all across the board; even staunch Keynesians conceded that Friedman/Phelps had been right (indeed, they may have conceded too much [emphasis added]), and the vertical long-run Phillips curve became part of every textbook.”

My early work on Hayek and Keynes (see here and here) argued that this development was important, but misleading. The then current business cycle research and its newer variants could benefit from re-examining the issues at the heart of the Hayek-Keynes debate.

Money, banking, finance, and capital structure were, and still are, for the most part ignored in much of the new (post-Friedman-Phelps) macroeconomics including the new–Keynesian approaches. In this regard, Hayek (and Mises) had then, and has now, more to offer than Keynes.

Recent papers by respected mainstream economists are beginning to recognize that attention to Hayek and Mises can be useful. Guillermo Calvo of Columbia University, in a recent paper [PDF], has even gone so far as to argue, “the Austrian school of the trade cycle was on the right track” and that the Austrian School offered valuable insights and noting that:

There is a growing empirical literature purporting to show that financial crises are preceded by credit booms including Mendoza and Terrones (2008), Schularik and Taylor (2012), Agosin and Huaita (2012), and Borio (2012).

Calvo adds “[t]his was a central theme in the Austrian School of Economics.”

Claudio Borio highlights what Austrians have long argued is a key flaw in inflation-targeting or stable-money policy regimes such as many central banks either adopted or emulated during the 1980-2008 period. This flaw contributed to back-to-back boom-busts of the late 1990s and 2000s:

A monetary policy regime narrowly focused on controlling near-term inflation removes the need to tighten policy when financial booms take hold against the backdrop of low and stable inflation. And major positive supply-side developments, such as those associated with the globalisation of the real side of the economy, provide plenty of fuel for financial booms.

Borio thus recognizes that a time to mitigate a bust is (contra-Keynes) during the boom:

In the case of monetary policy, it is necessary to adopt strategies that allow central banks to tighten so as to lean against the build-up of financial imbalances even if near-term inflation remains subdued.

William R. White, another economist who has worked at the Bank of International Settlements (BIS) and has been influenced by Hayek, has come to similar conclusions as does Calvo, who argues “Hayek’s theory is very subtle and shows that even a central bank that follows a stable monetary policy may not be able to prevent business cycles and, occasionally, major boom-bust episodes.”

In the current environment, many, including Krugman, have argued for a higher inflation target or a higher nominal GDP target to jump start the current sluggish recovery.

Austrian business cycle theory on the other hand, as recognized by Borio and Calvo, provides analysis on why such a policy may be ineffective and if temporarily effective in the short run, harmful if not destructive, in the long run. (See here and here for more.)

An easy money and credit policy impedes necessary re-structuring of the economy and new credit creation begins a new round of misdirection of production leading to an “unfinished recession.” Calvo expounds:

Whatever one thinks of the power of the Hayek/Mises mix as a positive theory of the business cycle, an insight from the theory is that once credit over-expansion hits the real sector, rolling back credit is unlikely to be able to put “Humpty-Dumpty together again.”

It is too bad it took back-to-back harmful boom-bust cycles for the profession at large to begin to again examine Austrian insights, but it does illustrate how foolish Krugman is when he argues Austrians have nothing to bring to the table.

Stagnation [for Carson]

Tyler Cowen’s thesis is that economic growth is leveling off and rates of return decreasing because we’ve already picked the “low-hanging fruit” (meaning innovations and investments that have high returns). The stagnation in GDP and median income in recent decades means “the pace of technological development has slowed down,” and the general population is benefiting less from new ideas.

I would argue, rather, that measured economic growth and income have slowed down precisely because of the increased pace of technological development.

The important trend behind the disappearance of “low-hanging fruit” is the decoupling of improved material quality of life from monetized measures of economic growth and income. Improvements in quality of life—although very real—don’t show up in conventional econometric terms.

Intensive development—increased efficiency in the use of inputs—isn’t necessarily reflected in increased money returns. Unless they’re turned into a source of rents by restrictions on competition, innovations that reduce production costs will benefit consumers in lower prices and better products.

Such rents are central to the business model of “cognitive capitalism”—the “progressive” model of capitalism pushed by Bill Gates and Warren Buffett. The most profitable industries in recent years have been those that depend on returns from “intellectual property.” But such artificial scarcities are fast becoming unenforceable, and technologies of abundance are growing so rapidly that they can’t be enclosed as a source of rents.

If anything, we can expect an implosion in metrics like GDP in the coming years, even as quality of life improves enormously.

Cowen almost gets it at one point. “[I]f our food supply chain harvests, retails and sells an apple for $1, that adds a dollar to measured national income.” Exactly: GDP measures value produced in terms of the total cost of inputs consumed—not the use-value we consume, but how much stuff was used up producing it. So anything that reduces the input costs of our standard of living seems to show up as negative growth.

Actually, Cowen contradicts his own thesis. He argues that official GDP figures exaggerate growth because so much of it is simply waste. But that undermines his treatment of reduced money incomes as a proxy for reduced growth in standard of living. If the additional portion of the GDP we spend on waste—and the hours we worked to pay for it—simply disappeared, we’d be better off by that much. He can’t argue both that economic growth is the best measure of technical progress and that the levels of growth that have occurred have too little to do with real productivity.

To be sure, Cowen does address the supposed diminishing returns of technological progress in terms of personal use-value. The blockbuster innovations with the biggest effect on our daily lives, he says, have already been adopted: antibiotics, automobiles, refrigerators, television, air conditioning. There’s been far less change in the character of daily life since 1960 than before. Aside from the Internet, recent innovations have been mostly incremental.

The Internet itself, Cowen argues, may be important in terms of personal happiness, but not of generating either revenue or employment. But to treat revenue generation and employment as ends in themselves—rather than a way to pay for stuff—is perverse. If the price of what we need falls because the amount of labor and capital needed to produce it falls, then we need less revenue—and less labor—for the same standard of living. The real significance of what Cowen mistakenly calls “stagnation” is that a growing share of our needs is being decoupled from revenue by technologies of abundance.

The reduced wage employment needed to produce our standard of living, as such, is a good thing. What’s bad is when artificial property rights enable rentier classes to appropriate the benefits of increased productivity for themselves. Our goal should not be to increase the number of “full-time jobs,” but to make sure that the productivity of the hours we do work is fully internalized.

Cowen focuses mainly on the Internet as part of the furniture of daily life—the fun of web surfing—to the neglect of a far more important benefit: the basic way society itself is organized, the relative power of the individual and networks versus large institutions, and the declining ability of hierarchies to enforce their will on us.

His focus on the objects of daily life ignores revolutionary changes in the way they’re made and on the structure of the economy. There’s not such a revolutionary change in going from picture tubes to gel panels, or from carburetors to fuel injectors. But there’s an enormous difference between John Kenneth Galbraith’s mass-production oligopoly economy and one of networked garage shops using cheap machine tools.
