It must be hard to be a Monetarist!




Stephen Colbert is right; reality does have a liberal bias.  Or at least that is what the new study by D’Agostino & Surico posted at voxeu.org seems to suggest.  They forecast inflation using a Vector Auto-Regression (VAR) model.  They test for the relation between inflation and money, inflation and output, and inflation and past inflation in the United States from 1904 to 2004.  Their results show that:

“Under the gold standard, the Bretton Woods system and most of the great moderation sample [in other words, almost the whole sample] money growth and output growth had no marginal predictive power for inflation;”

And “output growth had marginal predictive power for inflation in only two periods: (i) the years that extend from the great inflation of the 1970s to the early 1980s … and (ii) the years between 1997 and 2000.”

In other words, money supply is never significant, output very seldom, and the only thing that really matters is past inflation.  So much for monetarist views according to which money supply explains economic history!  In the face of this paper, the only puzzling question is why the Monetarist view of history, as expressed in Friedman & Schwartz, and more recently in Meltzer, is still so popular.

There explicit conclusion is that: “the results reported in this column are consistent with the idea that a policy regime which successfully stabilizes inflation makes it harder to improve upon the forecasts based on “naive” models.”  English translation: the conventional idea that too much demand triggered by monetary expansion causes inflation does not work when compared to the simple idea of inflationary inertia.  Inflation is high if it was high in the past.

The first period in which output growth has predictive power is, incidentally, a period in which commodity prices boomed, and that means that inflation might be orthogonal to output growth, even if both are correlated.  The second period was associated to both a stock market and a housing bubble, and asset price inflation may also not result from full employment (output increasing beyond its potential).

They should have explicitly noted that periods (monetary regimes) with low inflation could not be explained simply by lack of excess demand or monetary expansionism, since those are ruled out by their own econometric work.  I wonder what explains monetary regimes that produce price stability?  Interestingly enough the authors do not seem to have an interest in what causes past inflation or price stability!

PS: Thanks to Steve Bannister for directing me to their post.  He may have something to say later on the advantages and the limitations of the econometric techniques used by the authors.  Also, he is giving a talk on heterodox approaches to econometrics this coming Friday.  Will post a link to his talk later.

Top marginal rates and income distribution



A little aside prompted by the top marginal rate graph I posted yesterday. If you graph it together with the share of income of the top 10% of the population (data available in Emmanuel Saez’s webpage), you see that as the top marginal rate goes up in the 1930s the income share of the wealthiest individuals falls, and vice versa in the 1980s. Not rocket science. And clearly there are several other factors that explain the down and up change in the income share of the wealthiest, from the strength of unions after the Wagner Act and their current struggles (e.g. in Wisconsin), to the education boost of the GI Bill and the current increases in the cost of public education, to the political changes in the Republican Party after the rise of the conservative movement.

PS: I excluded the earlier years of the 20th century, because of the sharp increases in top rates during World War I.

Taxes and class warfare



Doing my taxes (yep another procrastinator) and getting the little Tea-bagger (talk about darker side!) inside me a bit angry.  Just read this week David Cay Johnston's great piece for the Willamette Week debunking the myths about taxes (e.g. the rich pay most of the taxes, but not really, just most of the income tax, and so on).  He shows that the worker making the median wage pays around 23% of his/her income as compared to almost 19% for the 400 wealthiest Americans (See Table below).



If that does not lend support to Obama's proposal to allow the top rate to increase again to 39.6%, I don't know what does.  The graph below (via thruth&politics) shows the top marginal tax rate over time.



We do not need to go back to the good old times of that Socialist, Eisenhower, when marginal tax rates where 91%, but it would certainly help to raise taxes on the rich, if you are really concerned about public debt.  It seems that class warfare wasn't that bad!

The age of uncertainty



This video of the old series by John Kenneth Galbraith is fantastic.  The other parts are also available. A little nugget in the begging is the video of John Maynard Keynes.  In an era of gold bugs, a good reminder of why the Gold Standard did not work.

Moby and MoveOn.org against the budget deal.  A bit dramatic, but right on target.

Commodity prices and inflation

Krugman shows that according to a paper on the Chicago Fed, there is no evidence of a connection between core inflation (without energy and food prices) and commodity prices. He should have said no evidence in the United States.  In fact, when you look at developing countries the connection might be stronger.  That depends on the pass-through effect from commodity (tradables) prices to non-tradables.



Also, note that the Consumer Price Index (CPI) would be affected.  For example, if we look (see graph above) at the Argentine data (using terms of trade and consumer prices) there is a clear effect of commodity prices on CPI inflation.  That does not mean that I would favor hiking rates of interest, and putting a break, in the US or Argentina for that matter, on expansionist policies.  Quite the opposite, the suggestion is that policies to stabilize the wild fluctuation of commodity prices, for starters try to control the speculation with commodity derivatives, might be a good idea.

It's not the size, but how you use it: A note on the debt-ceiling limit


According to the New York Times we barely averted the government shutdown to move on to the war over the debt-ceiling limit. Tim Geithner has argued that the government will hit, no later than May 16, the federal debt-ceiling limit of US$ 14,2 trillion. In fact, contrary to what one might expect the debt-ceiling limit is often increased. The question, of course, is whether the increase in debt vis-à-vis the capacity to repay, normally measuring debt as a share of GDP, is of such magnitude that the economy is doomed.

When we hit the limit, federal public debt will be slightly below the 100% mark. Historically, is not the highest debt-to-GDP level in the US, neither unprecedented by historical standards. The graph below shows British debt-to-GDP from 1692 to 2011.



The peak in British debt, at the end of the Napoleonic wars, was about 260%, and it had grown consistently during the 18th century. David Hume argued in 1752 that: “either the Nation must destroy public credit, or public credit will destroy the Nation.” He was obviously wrong (that’s probably why his theories are still taught by economists!). Not only public debt, which is what he meant by public credit, did not bankrupt the UK, but also it allowed for an Industrial Revolution and the victory in the hegemonic wars against France. A pile of debt laid the foundations for the Victorian economy boom and world dominance.

Note that during the 18th century the UK had higher taxes to pay for the higher debt levels than France, but interest rates were considerably lower, which implied that the burden of debt (interest payments out of total spending) was not much bigger than in France. James MacDonald has a very good book on the British debt history.

This suggests that more important than the growing debt-to-GDP ratio in the US is how it is used, and how it is funded. The function of the deficits and debt is more important than the size, as Abba Lerner argued. Hence, if we spend money to create jobs (e.g. remaking the infrastructure) and tax the rich rather then cut spending on programs for the poor, increasing the debt-ceiling limit should be a no-brainer.

More on Center-Periphery cycles


As pointed out in a previous post, Yilmaz Akyüz describes the stylized post-Bretton Woods boom and bust cycle nicely. From the perspective of the developing world, low interest rates in the US lead to an inflow of capital, currency appreciation, and often times a commodity price bubble. As the current account worsens, a trigger event causes a sharp withdrawal of capital (which often results in a debt crisis). Reductions in the level of income then adjust the balance of payments. From the perspective of the US, this has been associated with debt driven consumption cycles.

But the post-Bretton Woods US is only the most recent protagonist in what was originally a British drama. Throughout the 19th century, the British, often responding to rising commodity prices, pulled "gold from the moon" by manipulating the Bank of England discount rate. From the Baring Crisis of the 1890's to the 1860's cotton boom in Egypt, to the US boom of the 1830's, to the first Latin American debt crisis in the 1820's, the British were able to direct the international flow of capital and thus the fates of peripheral countries. The cycle is astoundingly similar. Long periods of disinflation in the center, associated with capital inflows and commodity booms in the periphery. Peripheral exchange rates appreciate, a large external account deficit opens, and the whole process is ended with a sharp increase in interest rates by the central bank in the core.

The example of the US in the late 1830's is particularly ironic as it learned some harsh lessons in the school of international financial hegemony that it now conducts. Long term capital began to flow into the US after during the British recovery of 1833-34. It was associated with a rapid increase in commodity prices, particularly cotton. As the dollar appreciated against the pound, a large trade deficit emerged, as Americans bought British manufactured goods. A decline in the British bank rate in 1835 further increased the mania. By 1836 the Bank of England increased it's discount rate, causing commodity prices to collapse and throwing the US into recession. High real interest rates then resulted in a wave of US state defaults not unlike the Latin American defaults of decade earlier (notably Andrew Jackson had paid of the federal debt with revenues from land sales - else we might have had a full on sovereign default!).

All of which is to say that the cycle is not new. Even prior to the classical gold standard, the center has conducted the orchestra, while the periphery faces strongly asymmetric adjustments. It is however ironic that a country that used to be in a minor chair position now conducts. The difference of course is that as the 19th century came to a close and international competition mounted, the British turned inwards, increasing trade with countries within the Empire (as pointed out in DeCecco's fantastic book "The International Gold Standard: Money and Empire").

Is there something in the water at the IMF?


via Mark Thoma, Economist's View
The paper:IMF on inequality and growth

Whilst I haven't yet taken the time to delve into the 'metrics, this looks to be an interesting survey and addition to one of the fundamental macro questions: whence growth. Interestingly, the authors highlight the finding of the importance of (the lack of) inequality for continuation of "growth spells."

Given its history, it's fairly stunning that this would emanate from the IMF. Further, I think it's time to do a really good syllabus on the topic of growth and inequality. Inequality mavens, send us your links!

I'll be reading this one more closely, especially in the context of Matias' immediately preceding post.

Rediscovering Prebisch


Yilmaz Akyüz has written a very good post on the boom and bust cycles in the periphery or the less developed countries, resulting from long-term capital inflows and outflows coming from the center or developed countries. He notes that we are entering a fourth cycle since the collapse of Bretton Woods. The basic mechanism can be described as follows, a crisis in the center, which leads to low rates of growth and interest rates, creates the conditions for inflows of capital into the periphery.

The inflows, in turn, lead to a boom in the periphery that goes hand-in-hand with currency appreciation, and in some cases greater indebtedness and asset and commodity price bubbles. The appreciation weakens the external position in the periphery, and eventually something (e.g. higher interest rates in the center, a fall in the price of commodities, etc.) triggers a reversal of capital flows and a crisis in the periphery.

It must be noted that the three previous cycles, to which Akyüz refers, can be also observed in the US economy. The cycles in the periphery have been associated in the US to three debt-led cycles in which the boom was associated to appreciation of the currency, and asset bubbles that allowed consumption to increase, in spite of the stagnation of wages. Arguably, it is the American boom and bust cycles that drive the flows of capital, and the cycles in the periphery. So Raúl Prebisch still has a lot to teach us on the interaction between the center and the periphery!

Stop greed and idiocy!



Pending a miracle tomorrow there will be a government shutdown. Marx was right, history repeats itself, first as tragedy than as farce. The reasons are not difficult to understand. Carlo Cipolla, in his fantastic Allegro ma non troppo, explained that there are four kinds of people, the helpless, the intelligent, the idiot and the bandit. For us, the ones that matter are the idiots, that is, the “person who causes losses to another person or to a group of persons while himself deriving no gain and even possibly incurring losses.”

The Laws of Human Stupidity imply that non-stupid people underestimate the damaging effects of idiots. In particular, if there is an increasing number of bandits within the elite of the country (e.g. Republicans and his plutocratic friends) that want to plunder the budget, cutting taxes for the rich and cutting spending for the poor and the elderly, and a large number of idiots (e.g. the Tea Party), with only helpless people (e.g. the Democratic leadership) to avoid catastrophe, then as Cipolla suggested society is sure to go to Hell!

Cornel West on Obama and the Jobless

Via Naked Capitalism. This is not very recent, but worth your time.



This is harsh critique from a public intellectual that was, and still is in many respects, pro-Obama.  And yes he is right we DO need a New New Deal.

Playing the fiddle, while the economy burns

The new labor report is out (here) and the news... well there aren't any news really. 216,000 jobs created, which is barely above what is needed to deal with the growth in the labor force. The unemployment rate is down to 8.8%, and the average duration of unemployment is up to 39 weeks. Meanwhile Nero (I mean Republicans) play the fiddle while Washington burns, err I mean shuts down. The Economic Policy Institute (EPI) provides in depth analysis here.
