Gabriel Mihalache objects to Greg Mankiw‘s frequent invocation of Pigou in support of energy taxes he’d like to see enacted. In a thoughtful and eloquent rant, he makes an important point about the impossibility of implementing an optimal tax “scientifically”:

[T]hey draw you in under the pretense of restoring efficiency—what’s fair is fair, right?—who would argue against efficiency? That’s like saying you don’t like puppies!

But once they get you with the externalities/Pigou/efficiency argument, surprise! They don’t provide you with a practical formula for Lindahl pricing, an econometric/empirical test—this does not exist (yet)—and instead each of the members of the Pigou Club starts pushing his own political agenda: some, like Becker or Greenspan, want to see reliance on foreign authoritarians regimes reduced, others, like Mike Moffatt, want to equal-out the marginal effect of taxes, etc. But guess what, all these otherwise noble political causes have nothing to do with Pigou’s work.

…I must strongly object to purely political proposals dressed-up as positive welfare economics/science.

I’ve often seen the taunt “even a broken clock is right twice a day” leveled at Fin/Econ pundits, especially those whose opinions don’t seem to track the stock market very well. I have a hierarchy of clocks. In my hierarchy, a broken clock is the second best kind of clock to be. And if you are an investor, I think you are better off trying to be a broken clock than any other kind. Here’s my rundown of clocks:

The Accurate Clock — Obviously, the best kind of clock is one that always tells the time correctly. In stock market metaphor, this refers to the pundit or trader who can accurately time the market, call actionable peaks and lows and be right far more often than she is wrong. An accurate clock can become wealthy at a rate proportional to its accuracy. A perfectly accurate clock could become a billionaire in a single busy day. But, there are no perfectly accurate clocks. It may be impossible to be even a moderately accurate clock.

The Broken Clock — The prototypical broken clock never moves. Its hands point steadfastly towards a single time of the day. Broken clocks have one great virtue: They get to be right twice a day. Always. Every day. They are the turtle to the accurate clock’s hare. Rather than chasing the time around all day, they wait for the time to come to them. Among investors, so-called “permabears” or “permabulls” are usually referred to as broken clocks. I don’t think it’s good to be a “perma” anything. The world changes. A good broken clock is an investor who makes smart decisions based on the best available analysis she has, and then waits to profit, even if circumstances change, even if she comes to doubt her original reasoning. Behavioral finance types refer to this approach with words like “status quo bias” or “endowment effects”, like these are bad things. That’s okay. Broken clocks probably make more money than behavioral finance types. Being a broken clock is a perfectly sensible strategy in a world where information is worse than imperfect and there will always be great reasons to bail and take losses on positions that will eventually be winners. Note that not all broken clocks are alike. The hands of many broken clocks move, just not at the right speed. Some broken clocks move more slowly than real time. These clocks will always get to be right sometime, but not necessarily twice a day. Then there are the clocks whose hands move fast, or even backwards. These clocks get to be right more often than twice a day! Broken clock investors don’t try to just be broken. They compete on the basis of how long they have to be wrong before they get to be right. But broken clocks know that they really have no idea what time it is, and that they’d better be prepared to wait. They avoid inherently time-limited securities like options, and are cautious with leverage, because they hate to be forced to quit while they are wrong.

The Not Broken, Not Accurate Clock — The very worst kind of investor is the clock that keeps perfect time, but it is just not set properly. This kind of clock is never, ever right. It’s surprisingly easy to be a not broken, not accurate clock. If a clock is not broken, odds are 11 out of 12 that it will never even get the hour right. Not broken, not accurate clocks are always chasing reality, constantly moving, and never winning. In stock market terms, not broken, not accurate clocks are persuaded that it’s reasonable to take losses when circumstance change (as they always do). They take positions for good and sufficient reasons and liquidate them for good and sufficient reasons. In the meantime, they usually fail to profit. Most people who try to be accurate clocks make it half there. They end up moving at precisely the rhythm of the market, but out of phase, buying high into optimism and selling low into despair. Capital markets love not broken, not accurate clocks in the same way you or I love might love pancakes.

It’s pretty clear that I’m a big fan of broken clocks. That’s self-serving, because I am one. That means I am usually wrong. I’m wrong right now, portfolio-wise. I’m knee deep in red. Whether that fact recommends my advice as authentic, or damns it as stupid, I’ll leave for you, dear reader, to decide.

Dean Baker has a very interesting piece trying to make sense of why, with headline productivity so high since the mid-nineties, wages have not kept pace. Dean Baker begins…

Most economists view productivity growth as being the key to rising living standards through time. The basic story of productivity in the post-war era is that growth was rapid in the years from 1947-1973, but then slowed sharply over the years from 1973-1995. Productivity growth then ticked up again in 1995 and has been relatively rapid since 1995.

1995, huh. That was quite a year according to this article by Aaron Krowne. Aaron argues that in 1995, an obscure loosening of US bank reserve requirments, and an abandonment by the Greenspan Fed of a “virtual gold standard”, gave rise to an era of unprecedented growth in broad money. In my own mind, 1995 corresponds to about the beginning of the “asset economy”, when wealth accumulation from capital gains rather than wage or business income became an unusually important driver of the US economy. Hmmm.

I have an monetarist intuition about wages during this period. Suppose that under certain circumstances fast money supply expansion results in asset inflation rather than goods inflation. Goods prices remain stable, the economy seems to grow at a moderate clip, but asset prices grow far faster than GDP. Sellers of productive capital (tractors, factory equipment, etc.) as well as workers then have to compete with the financial sector for investable funds. As expectations of asset appreciation increase, more investors choose to purchase stocks, homes, hedge funds, oil, or gold than to build factories, open businesses, and hire workers. Of course stocks have to be backed by firms, and homes have to be built, but on the margin, investment dollars are diverted from direct deployment as productive capital to purchasing paper assets via financial intermediaries. The net effect is a reduction of the “velocity of money” in the real investment sector, reducing input prices while at the same time diminishing future capacity. Input prices include wages.

In an environment where capital is drawn to appreciating financial assets, workers and vendors of productive capital have to make price concessions relative to productivity in order to attract funding. Rocketing asset prices should be expected to reduce the bargaining power of workers, and to exert downward pressure on their wages.

UPDATE: Shamed by Greg Mankiw and some awful grammar, I’ve performed major surgery on this post, prettying things up and dropping a long digression from the main point. (I’ll insert the original version into the comments for posterity). 2006-10-08 03:11 am EET

Mystery-blogger knzn packs an avalanche of insights into a very brief discussion of why China’s policy of puchasing dollars to peg its nominal exchange rate has not led to real appreciation via inflation in China. knzn is quite critical of Charles Schumer and Lindsey Graham, who’ve written an op-ed in the Wall Street Journal (via Mark Thoma) today in defense of a proposal that amounts to a faint and distant threat of tariffs on Chinese goods. I am broadly sympathetic to Schumer and Graham’s proposal, despite considering myself a staunch free-trader, and I think their point largely stands, despite problems that knzn and Greg Mankiw highlight. I hope he will forgive me for abusing his insights in support of a position he may not much like. Here’s knzn:

China today is a special case for several reasons. First, there is a rapid flow of workers into the industrial sector, and this flow is helping to prevent the inflation that might ordinarily attend an undervalued currency. Second, much of China’s foreign exchange intervention is sterilized, which is to say, China is making attempts to slow down domestic sources of demand to compensate for the foreign demand occasioned by its weak currency. Third, China’s government is effectively running a very large surplus, which also tends to slow down domestic demand. Fourth, arguably, China is following policies that encourage a high level of private saving, which also tends to slow domestic demand.

knzn whizzes through this like it was nothing, but there’s a ton of interesting stuff here. knzn’s first reason is conventional wisdom, fine as far as it goes, and as the vowelless one notes, “if China has a lot of workers available to do these jobs, whereas the US has only a few (relatively speaking), why shouldn’t trade be set up to create jobs in China rather than the US?”

But knzn’s second point left me standing naked on the shoreline in wonder. Countries that manage their exchange rates are supposed to sterilize their interventions. It’s like Central Banking 101. If China’s central bank prints Yuan to buy dollars, it’s got to borrow some of those Yuan back to avoid flooding the market with newly printed Chinese bills, right? knzn is having none of it, and of course he’s absolutely right to note that sterilization is just a fancy word for what central banks do when they want to restrain domestic demand to avoid inflation. What I considered central bank prudence, knzn considers cheating, “[S]terilized intervention, might reasonably be considered an unfair trade practice (and probably a foolish practice as well).” Central banks may “naturally” want to prevent their exchange rate policy from causing inflation, but doing so in effect pegs the real, rather than nominal exchange rate. While pegging nominal exchange rates need not impede trade balance adjustments (because those adjustments can occur via changes in the price level), pegging real exchange rates blocks trade adjustment entirely.

knzn’s third point is also a shocker. He notes that China is “effectively” running a large surplus. But hold the phone. Isn’t China running a significant fiscal deficit? Well, yes, if you consider only tax revenues. But, if you consider a consolidated income statement that includes China’s central bank, China’s deficit would be dwarfed by the piles of foreign currency flying into the vaults, net of sterilization costs (and even net of significant presumed valuation losses). So is knzn is right to refer to this as “a very large surplus, which also tends to slow down domestic demand”? I think he’s only half right, in a very subtle way.

Imagine that China did no sterilization, and purchased dollars with freshly printed Yuan to maintain its peg. This would maximize the surplus achieved by China’s government (including central bank). But it would also be a very loose, a stimulative monetary policy that might provoke inflation, as China’s central bank would be increasing the money supply dramatically. An unsterilized peg then has two paradoxical and countervailing effects, amounting to a stimulus and tax at the same time. It taxes holders of domestic currency, by increasing the cost in local money of forign goods (an upward shift in the supply curve for imports). But it stimulates domestic demand for all goods. The net effect is almost certain inflation of the price of imported goods (relative to the price that would prevail without intervention), but a mix of real GDP growth (to the degree that there is “slack” in the economy ) and inflation in the domestic economy.

Now let’s put all this together. If China were simply pegging its currency without sterilizing, it would stimulate demand for nonimported goods and services, but it might also stimulate inflation, permitting real exchange rate adjustment. But, by adjusting the degree of sterilization, it can seek a sweet spot that grows unsterilized money at a level chosen to maximize real GDP without provoking inflation, preventing real adjustment. The net effect is a synthetic tariff, raising the price of foreign goods while stimulating the domestic economy and providing revenue to the state. It’s no wonder that China’s trade partners object.

The very excellent Mark Thoma, under the title “Avoiding Protectionism“, quotes a very orthodox article from The Economist (subscription req’d). From that article…

The developed economies as a whole will still benefit hugely from trade with emerging economies. Increased competition and greater economies of scale will boost the growth in productivity and output. Consumers will enjoy lower prices and a greater variety of products, and shareholders will enjoy higher returns on capital. Although workers will continue to see their pay squeezed, they can still gain as consumers or as shareholders… [G]lobalisation is benefiting America’s economy… But in practice the average family has not seen such a gain because much of it has gone to those at the top or into profits. This explains the lack of support for globalisation from ordinary people. Unless a solution is found to sluggish real wages and rising inequality, there is a serious risk of a protectionist backlash. Rather than block change, governments need to ease the pain it inflicts in various ways: with a temporary social safety-net for those who lose their jobs; better education to equip workers for tomorrow’s jobs; and more flexible labour markets to encourage the creation of new jobs… More controversially, governments may need to redistribute the benefits of globalisation more fairly through the tax and benefits system.

As long-time readers may know, this sort of rehash of the “free trade” catechism makes my blood boil. Why? Because I am deeply, pro-free-trade and proglobalization, and this sort of palaver threatens to discredit these important projects for a generation, when the current nightmare masquerading as free trade unwinds. As Brad Setser has noted, what is at issue is not the globalization per se, but the form that globalization is now taking that is the problem. Under this globalization, not some Econ textbook idealization, The Economist‘s case simply does not hold. For example:

Consumers will enjoy lower prices and a greater variety of products, and shareholders will enjoy higher returns on capital. Although workers will continue to see their pay squeezed, they can still gain as consumers or as shareholders.

These statements have simply been untrue, empirically, for American workers in the last five years, and the future looks even bleaker. Despite remarkable efforts of Wal-Mart and heavily subsidized Asian exporters, the median US worker has not seen lower prices, relative to the value of her labor. Living as a typical American has grown more expensive, when measured in median-worker-hours, not less, despite that worker’s apparently increased productivity. And this during a period in which supply chain innovations and an artificially strong dollar (vis Asia) have blown strong, disinflationary headwinds. Should the US dollar reprice, the road will only get harder.

The median worker, having been unable to benefit from globalization as a consumer, can hardly be expected to do so as a shareholder. A rising real cost of living implies less savings, or what we observe in fact, dissaving. At the same time workers are losing the purchasing power of their labor, they are losing the ability to participate in increasing returns to capital.

I could rant on and on about the patronizing incoherence of The Economist piece. [*] But enough. Let’s get to the root of the problem: This globalization has proceeded in a manner that violates the assumptions of the traditional (and correct!) case for free trade. The problem is not that emerging market labor is “too cheap”, or that “the global capital-labor ratio” has shifted. It is that advanced countries, especially the United States, are not paying for the goods and services received with the current provision of goods and services in exchange, but instead with promisary notes that may or may not be honored in real terms. The real-economy case for free trade is based on the idea of each nation producing as much and as best as it can in the domains in which it has comparative advantage, and exchanging that production for what others produce well. The exaggerated use of credit in international exchange (visible in the stockpiled reserves of emerging market central banks and national investment funds) has turned this case on its head. Rather than shifting production in “advanced economies” to align with changing comparative advantage, credit-based globalization encourages a retreat from tradables production altogether, as no real goods or services need be exchanged to receive tradables from elsewhere. The traditional case for free trade is simply not compatable with a regime in which some countries persistly provide, and others persistently accept, credit in exchange for real goods and services.

Which leads me to the question that serves as the title of this essay. Advanced economies don’t necessarily need tariffs, or subsidies, or any of the traditional arsenal of policies that fall under the rubric and epithet of “protectionist”. All they need to do is insist, to others and to themselves, on “paying cash, not credit”. Although intuitive, this formulation is strictly speaking meaningless, since modern money is a form of debt. Perhaps a better way of stating this is that advanced economies should, in fact make broadly balanced trade a non-negotiable policy objective, not as a form of protectionism, but in order to uphold the assumptions and preconditions required to ensure that free trade is beneficial.

A balanced trade policy could, and might sometimes need to be, enforced through measures that look atavistically protectionist. But not usually. Policies like the one Warren Buffet has proposed would be reasonable. Or the US Fed’s famous “dual mandate” could simply be expanded to a “triple mandate”, in which balanced trade is an explicit objective. When Americans, directly or via governments, are buying too much on credit from trade partners — when US trade is deteriorating out of balance — the Fed should increase the cost of taking on more debt. (In the short run, that might conflict with the Fed’s other mandates. But in the long run, full employment requires an economy that produces tradables sufficient to pay for wage-earners imports.)

Free trade is a great idea, when it is real goods and services being traded, rather than promises which will either be painfully kept or painfully broken. We should give it a try.

Greg Mankiw, Harvard prof, former CEA chair, and most importantly famed econblogger wrote this very fine paper several years back. Though there’s a bit of math, overall the paper is very common-sensical, and quite readable. Here’s my favorite bit:

Proposition 3: Government debt increases steady-state inequality.

Although… government debt does not affect the steady-state capital stock and national income, government debt does influence the distribution of income and consumption in the savers-spenders model… A higher level of debt means a higher level of taxation to pay for the interest payments on the debt. The taxes fall on both spenders and savers, but the interest payments go entirely to the savers. Thus, a higher level of debt raises the steady-state income and consumption of the savers and lowers the steady-state income and consumption and the spenders. The spenders, however, already had lower income and consumption than the savers (for only the savers earn capital income). Thus, a higher level of debt raises steady-state inequality in income and consumption.

This is a very straightforward argument: The government borrowing today to tax tomorrow is a non-event, if the monies not taxed today are all invested at a return that precisely covers the deferred taxation. But if “savers” invest the funds not taxed while “spenders” consume more than they would have, the savers are left unaffected but the spenders are left worse off when the bill comes due. (In Mankiw’s model, savers are not unaffected, but positively gain, as higher current consumption by spenders and government yields rising returns to savers, who invest and earn more than they otherwise would have.)

Given all the recent sturm und drang over inequality and the degree to which it can be accounted for by public policy, I’m surprised that this argument hasn’t featured more prominently. Given the United States’ current fiscal policy and the concern over inequality today, you’d think the idea of deficits exacerbating inequality would really bite.

Some comments:

1. The effect that Mankiw describes would be lagged: deficit spending now yields greater inequality over time.
2. It is somewhat insidious, in that deficit spending today increases consumption equality today, as typically poorer spenders consume more than they otherwise would, and live more like wealthier savers.
3. To counteract this effect, having a progressive tax system isn’t enough. A government that causes inequality through deficit spending would have to increase the progressivity of taxation in proportion to its borrowing in order to undo the increased inequality. Progressivity here would mean adjusting effective tax rates paid by cohorts. (The proportion of total taxes paid by spenders would increase even without policy changes, as a reflection of growing inequality.)

I’d love to see Mankiw extend his model to include not only domestic spenders and savers, but also foreign savers not subject to many US taxes. Also, if monetization of government debt is permitted as an alternative to (or a form of) taxation, how would that affect the relative wealth of domestic spenders, domestic savers, and foreign savers?

Note: Mankiw issued a minor correction for this paper, though it does not affect the argument discussed above.

Some of the best and brightest econbloggers are having a debate on whether there are negative externalities associated with wealth inequality, and whether these might merit government intervention to remedy. Unfortunately, the debate has gotten lost in a colorful, but unhelpful, discussion of “spite” (on the part of rich people) and “envy” (on the part of the poor). However entertaining this may be, it quite misses the point.

Very large wealth inequality has a huge, tangible negative externally in all existing political systems that has nothing to do with idiosyncratic emotional reactions. Wealth inequality leads to large, utility-destroying errors in public policy.

In the real world, under democratic capitalism, stalinist communism, feudal monarchies, you name it, there is a strong correlation between actual wealth and political power. (Under some systems this might be masked by differing institutions of wealth and property, but facts on the ground proved Comrade Stalin to have a nicer car than Comrade Sven.) Correlation is not causation: In some systems political power precedes wealth, and in others wealth brings with it the capacity to garner influence. Nevertheless, the relationship is strong, everywhere. The wealthy always have disproportionate political power.

Wealthy people — and I mean the best intentioned wealthy people, not the corrupt — make political decisions to improve the world as they see it. The greater the degree of wealth inequality, the greater the difference between the world those at the very top experience and the experience of the vast majority. This leads to errors in judgement, policy changes that improve the world the rich live in while harming the world that the not-so-rich inhabit, and very large utility losses when the not-so-rich are numerous. The best intentioned of the wealthy may try to mitigate this by reading, thinking about the less fortunate, etc. etc. But these exercises are a poor substitute for experiencing the world as most people experience it, and suffering the consequences of poor leadership directly. And power correlates with wealth much more than it correlates with diligence and skill in understanding the world beyond ones own experience.

Utility losses due to misguided generalizations of their own experience by the wealthy and powerful may be inevitable. But quantities matter. A society in which “the wealthy” represent a large fraction of the population who live not to differently from the less wealthy will make fewer and less costly errors than one in which a realtively small, very wealthy group lives very differently from the rest.

It is always worth remembering that wealth is not about what you have, it is about what you do. Dollars, cents, and bars of gold are only shadows of the past, that to a greater or more often lesser degree help today’s wealth open a door into tomorrow’s. Economists forget this, and treat wealth as quantifiable and money as a store of value, when in fact value must be recreated every day. A nation’s “stock of wealth” may be fifty trillion dollars, but wait and see how little wealth $50 trillion buys if that nation slows in the dance of producing and serving to meet its own wants and the wants of others.

Money is key to wealth for individuals and firms in a healthy, stable economy. Money is irrelevant to the wealth of societies at large. Economists err when they measure a society’s “real wealth” by agglomerating the prices of things and adjusting for an slippery quantity called inflation. Real wealth is about matching the production of goods and services, or their sustainable acquisition through trade, with the very diverse wants and needs of people. Refracting these questions through the a fiction of dollars and cents provides analytical convenience but not accuracy.

I’ve been pulled from a period of post-nuptial dissolution and lassitude by an astonishing article in yesterday’s Wall Street Journal on private equity buyouts. It describes a simple game. Private equity firms persude creditors fund highly leveraged buyouts. The bought-out firm then takes on more debt to quickly pay large sums to the private equity firm, its new owner and manager, in the form of management fees and dividends.

Consider Intelsat. According the the WSJ article, private equity investors put up $515 million, while creditors footed the remaining $5.5 billion to purchase the communications satellite business. Within two years, the private equity investors had extracted more than $576 million in fees and dividends, while still retaining full ownership of the firm. Now that’s a good position to be in. After two years, while the underlying firm was struggling, renegging on promised employee benefits, and showing a negative net worth, it’s owners had already earned 5.75% annual returns on their stake and recovered their capital in full, while still retaining control of the company and claim to any future profits it might earn! Alluding to a previous post, this is a deal right on the dotted line. For zero net investment, the private equity firm gets to gamble taking all the profit and growth a 3 billion dollar firm can generate, or walking away from the table with a bit of bad publicity and the unwinding of some legal entities.

It’s easy, as is apparently the German custom, the think of private equity firms as “locusts”. But this is capitalism, and people are supposed to figure out ways to exploit unusual opportunities. It’s not the sharks who are feeding, but the rare, bloody meat floating in the water that’s the problem here.

There’s an old math cliché that you can prove any proposition so long as division by zero is permitted. I think a finance version of this cliché would be that anything is possible if there’s a mispricing in any market that can’t undone by its exploitation. Credit markets for the past half-decade have matched this description. Central banks have held money cheap, despite unprecedented and every growing use of borrowed funds by everyone from strapped consumers to eager-to-please businesses to multibillion dollar investment funds. In unmanipulated markets, the orgy of borrowing that has characterized the last few years would have led naturally to tighter rates. Thanks to the US Fed, the People’s Bank of China, the freewheeling dollar lending of petrostates, and of course the Bank of Japan, that hasn’t happened. Money has been nearly free. Banks have had to compete mercilessly for the privilege of lending for any interest at all. Risk has been so sliced and diced and sold and apparently “managed” by the derivatives boom that many creditors have been made comfortable with positions that in the past would have looked like laughably bad deals for them. Global interest rates have been fixed by the behavior of central banks collectively and state-affiliated investment funds at absurdly low levels.

The current private equity boom is largely a means of exploiting that mispricing. The underlying businesses that are bought and sold are means to ends. It is not what they do, what new efficiencies or synergies or what not that can be introduced that matters. It is how well their assets can be used to justify continual leveraging, how cheaply they can be bought, how good a story can be told to keep the terms of borrowing from becoming too onerous even while cash is sucked from the firms by equityholders, that matters most. The underlying business then becomes a lottery ticket. If a firm can, in the course of doing a deal, build a really great company, put together several firms and take advantage of synergies, improve underlying efficiencies, then the value of all those improvements is pure profit for the private equity fund. Leveraged buyers have every incentive to try to build and improve the companies they float through. But in a world of artificially cheap credit, taking underperforming companies and turning them into great ones becomes secondary, gravy. An arbitrage opportunity is better than any risky investement. The first order of business for a rational private equity fund would be to find target investments through which to exploit mispricings in credit and risk can be efficiently exploited.

Of course this will all come apart, rather soon I hope. If collective state behavior does change (a very big if) and the era of absurdly cheap money ends, many of these heavily leveraged deals will go south, and we’ll have a predicatable wave of Enron-like scandals, as firms go bust, private equity funds write off their investments, and creditors sue them for fees and dividends they extracted from retrospectiovely insolvent companies. If central banks around the world are determined to keep money cheap, if China keeps ramping its exports and lending away all the proceeds for next to nothing, if the petrostates keep buying up dollar debt with all their oil proceeds, if the Bank of Japan and US Fed get spooked by the prospect of recession and hold rates low, we can put off much of this unpleasantness, but with much worse eventual consequences.

After all, it is not liquidity or interest rates or equity deals that matter in the enterprise of human wealth. It is the business of producing real goods and services. A world in which nominal wealth becomes detached from real production, and bound instead to cleverness in manipulating the machinery of high finance, is a world in which financiers will have an ever larger share of a progressively smaller pie.

I think it’s very simple.

They know something bad is going to happen. It could be a deflationary recession, it could be out of control inflation. In a world awash in liquidity and debt, in which the US Fed has limited effective control over the quantity of money and the quality of claims, either possibility is plausible.

The Fed doesn’t want to be blamed. Feds are historically blamed first for pushing interest rates too high (causing a deflationary recession), and second for letting inflation get out of hand. So, the Fed’s first priority is not being blamed for acting too aggressively and causing a recession. They can avoid blame by pausing the rate hike cycle, if it seems decent to do so, or by moving 25 bp per meeting, if inflation numbers run high. That “measured pace” is now a kind of default, not a blame magnet, and anyway, it’s a Greenspan Fed strategy, so if contiguous 25 bp moves precede a recession, most of the blame goes to Bernanke’s predecessor. But the Fed also doesn’t want to be blamed for failing at its core mission of keeping inflation under control. So, in “jaw-jaw” mode — speeches, informal comments, etc. — Fed officials come off as hawkish, hoping to maintain their credibility as inflation fighters, and thereby reduce self-fulfilling expectations of increased inflation.

This is a fairly optimal strategy for avoiding blame. If a recession hits, blaming the Fed for being too aggressive will have limited traction. After all, the Fed only continued its predecessors policy of gently tightening, and only when inflation numbers clearly forced continued tightening. Blaming the Fed because Bernanke talked about inflation numbers exceeding his comfort levels in some speech is not going to take. The formal record will be one of very measured interest rate rises, and very moderate statements and minutes. If there’s a recession, it won’t be the Fed’s fault. If inflation continues to pick-up, the Fed can try to maintain its credibility by talking tough and continuing the 25 bp hikes. If the Fed really is “behind the curve” on inflation, and prices accelerate, eventually they might be blamed. But that involves incremental and subtle attributions of blame. They can always, actually “shock the market”, if things get out of hand and the blame for inflationary pressires gets palpable. But much better to threaten to do something radical (deniably, through third parties and rumors) than to take the risk of actually doing something, until something absolutely must be done, and the risk of serious blame can no longer be avoided.

I do think some kind of bad economic period is inevitable, though whether it looks like recession or stagflation or just modest inflation and sluggish real growth is uncertain. I’m not sure that I blame the Fed for avoiding blame. But I do blame the Greenspan Fed, and current administration, and the ossification of economic ideas into stale ideologies over a longer period of time, for getting the US economy into an obvious, big mess, while the best and brightest debated whether a garbage dump wasn’t the optimal outcome if something resembling a market happened to produce it.
