Paul Krugman: Addicted to Inflation

Posted: 18 Jul 2014 12:24 AM PDT

What does "inflation addiction" tell us?:

Addicted to Inflation, by Paul Krugman, Commentary, NY Times: The first step toward recovery is admitting that you have a problem. That goes for political movements as well as individuals. So I have some advice for so-called reform conservatives trying to rebuild the intellectual vitality of the right: You need to start by facing up to the fact that your movement is in the grip of some uncontrollable urges. In particular, it's addicted to inflation — not the thing itself, but the claim that runaway inflation is either happening or about to happen. ...
Yet despite being consistently wrong for more than five years,... at best, the inflation-is-coming crowd admits that it hasn't happened yet, but attributes the delay to unforeseeable circumstances. ... At worst, inflationistas resort to conspiracy theories: Inflation is already high, but the government is covering it up. The ... inflation conspiracy theorists have faced well-deserved ridicule even from fellow conservatives. Yet the conspiracy theory keeps resurfacing. It has, predictably, been rolled out to defend Mr. Santelli.
All of this is very frustrating to those reform conservatives. If you ask what new ideas they have to offer, they often mention "market monetarism," which translates under current circumstances to the notion that the Fed should be doing more, not less. ... But this idea has achieved no traction at all with the rest of American conservatism, which is still obsessed with the phantom menace of runaway inflation.
And the roots of inflation addiction run deep. Reformers like to minimize the influence of libertarian fantasies — fantasies that invariably involve the notion that inflationary disaster looms unless we return to gold — on today's conservative leaders. But to do that, you have to dismiss what these leaders have actually said. ...
More generally, modern American conservatism is deeply opposed to any form of government activism, and while monetary policy is sometimes treated as a technocratic affair, the truth is that printing dollars to fight a slump, or even to stabilize some broader definition of the money supply, is indeed an activist policy.
The point, then, is that inflation addiction is telling us something about the intellectual state of one side of our great national divide. The right's obsessive focus on a problem we don't have, its refusal to reconsider its premises despite overwhelming practical failure, tells you that we aren't actually having any kind of rational debate. And that, in turn, bodes ill not just for would-be reformers, but for the nation.

'Do Patents Stifle Cumulative Innovation?'

Posted: 17 Jul 2014 08:31 AM PDT

Joshua Gans

Do patents stifle cumulative innovation?: There has been a movement that began with the notion of the anti-commons that suggested that, whatever the other benefits and faults might be with the patent system, a fault that really matters for the operation of the system and for growth prospects (a la endogenous growth theory) is how patents might stifle cumulative or follow-on innovation. ...
The standard, informal theory of harm here is that follow-on innovators, feeling that they can't easily deal with the patent holder on the pioneer innovation, decide that the risks are too high to invest and so opt not to do so. To be sure, this 'hold-up' concern is not good for anyone, including possibly the patent rights holder who loses the opportunity to earn licensing fees from applications of their knowledge. Suffice it to say, this has been a big feature of the movement against the current strength and, indeed, existence of the patent system.
One issue, however, was that the evidence on the impact of patents on cumulative innovation was weak. Mostly that was due to the problem of finding an environment where impact could be measured. ...
For this reason, all previous attempts concerned intermediate steps — most notably, the impact of patents on citations whether in publications or in patents. This includes work by Fiona Murray and Scott Stern, Heidi Williams and Alberto Galasso and Mark Schankerman. While there is some variation, this work showed, using various clever approaches, that patent protection (or other IP changes) might deter cumulative innovation upwards of 30%. That's a big effect and a big concern even if the results were somewhat intermediate.
At the NBER Summer Institute a new paper by Bhaven Sampat and Heidi Williams (the same Williams from the previous paper) actually found a way to examine the impact of patents on follow-on innovations themselves. ... The ... paper presents pretty convincing evidence that you cannot reject zero as the likely prediction. That is, the effect patents on follow-on research appears to be non-existent. ...
Suffice it to say, while it is only a particular area, this is evidence enough that should cause many to identify and change their bias regarding the impact of patents on cumulative innovation. ...

The original post has a much longer discussion of the theory and evidence.

'Debt, Great Recession and the Awful Recovery'

Posted: 17 Jul 2014 08:16 AM PDT

Cecchetti & Schoenholtz:

Debt, Great Recession and the Awful Recovery: ... In their new book, House of Debt, Atif Mian and Amir Sufi portray the income and wealth differences between borrowers and lenders as the key to the Great Recession and the Awful Recovery (our term). If, as they argue, the "debt overhang" story trumps the now-conventional narrative of a financial crisis-driven economic collapse, policymakers will also need to revise the tools they use to combat such deep slumps. ...
House of Debt is at its best in showing that: (1) a dramatic easing of credit conditions for low-quality borrowers fed the U.S. mortgage boom in the years before the Great Recession; (2) that boom was a major driver of the U.S. housing price bubble; and (3) leveraged housing losses diminished U.S. consumption and destroyed jobs.
The evidence for these propositions is carefully documented... The strong conclusion is that – as in many other asset bubbles across history and time – an extraordinary credit expansion stoked the boom and exacerbated the bust. Of that we can now be sure.
What is less clear is that these facts diminish the importance of the U.S. intermediation crisis as a trigger for both the Great Recession and the Awful Recovery..., while the U.S. recession started in the final quarter of 2007, it turned vicious only after the September 2008 failure of Lehman. ...
What about the remedy? Would greater debt forgiveness have limited the squeeze on households and reduced the pullback? Almost certainly. ...
The discussion about remedies to debt and leverage cycles is still in its infancy. House of Debt shows why that discussion is so important. Its contribution to understanding the Great Recession (and other big economic cycles) will influence analysts and policymakers for years, even those (like us) who give much greater weight to the role of banks and the financial crisis than the authors.

They also talk about the desirability of "new financial contracts that place the burden of bearing the risk of house price declines primarily on wealthy investors (rather than on borrowers) who can better afford it."
