A generation ago Michael Kremer wrote a superb paper: Michael Kremer (1993): "Population Growth and Technological Change: One Million B.C. to 1990", Quarterly Journal of Economics 108:3 (August), pp. 681-716 http://tinyurl.com/dl20160727a.
Kremer saw human populations as growing at an increasing rate over time. Population reached approximately 4 million by 10000 BC, 50 million by 1000 BC, and 170 million by the year 1. Population then reached 265 million by the year 1000, 425 million by 1500, and 720 million by 1750 before the subsequent explosion of the British Industrial Revolution and the subsequent spread of Modern Economic Growth.
With respect to last Thursday: One piece of background is all-important in assessing the decision: ObamaCare is RomneyCare.
The health-care reform plan that Mitt Romney proposed when he was Governor of Massachusetts is the health-care reform plan that Barack Obama proposed. RomneyCare made it through the Massachusetts legislature with only two dissenting votes. No office-holding Republican complained that RomneyCare was bad policy, or would destroy the economy, or would be unconstitutional, or whatnot--for it was the signature policy initiative of a Republican governor. The mandate that was at its core? That was the conservative Personal Responsibility principle. And remember the centerpiece of the Bush administration's Social Security privatization proposals: it was an individual mandate to regulate 'inactivity': to require that people who had not established their own private individual retirement accounts do so.
Had the issue of 'inactivity' reached the justices in the form of a challenge to a Republican mandate to purchase retirement accounts rather than a Democratic mandate to purchase health insurance, the Republican justices would have voted the other way.
...What would the world look like if everybody had everything they wanted or needed? Delving deep into the details and intricacies of 24th century society, Trekonomics explores post-scarcity and whether we, as humans, are equipped for it. What are the prospects of automation and artificial intelligence? Is there really no money in Star Trek? Is Trekonomics at all possible? Manu will be in conversation with UC Berkeley economics professor Brad DeLong.
Next week's meeting of the Federal Open Market Committee (FOMC) includes a press conference with Chair Janet Yellen. These are five questions I would ask if I had the opportunity to do so in light of recent events.
There's no modern work to teach alongside Theory of Justice and Anarchy, State, and Utopia that really gets at what's interesting about Burkean or social conservatism.... Any book plucked from the past that was concerned with yelling "stop!" tends to date badly to any modern reader who does not think he's already living in hell-in-a-handbasket... talks about how everything will go to hell if the [Jim Crow] South isn't allowed to remain the South.... Oakeshott['s]... "Rationalism in Politics" end[s] up feeling faintly ridiculous by the time he's talking about women's suffrage.... I might say Schumpeter, Capitalism, Socialism, and Democracy, and Kristol, Two Cheers for Capitalism, but the former isn't really distinctively conservative enough and I'm not sure the latter is a classic.
In my view, you go with Polanyi's The Great Transformation--which gets the rational kernel inside the mystical conservative shell--or you go home.
And this is apropos today because Nick Kristof is writing more bilgewater for the New York Times:
Updated from: Live from Over the Rocky Mountains: I see that the War on Nate Silver has broken out again, with another article less appetizing than bilgewater in The New York Times, written by Jim Rutenberg:
Still more recently--as in Tuesday--the data journalist Nate Silver... gave Hillary Clinton a 90 percent chance of beating Bernie Sanders in Indiana. Mr. Sanders won by a comfortable margin of about five percentage points.... The lesson [from Eric Cantor's defeat] in Virginia, as the Washington Post reporter Paul Farhi wrote at the time, was that nothing exceeds the value of shoe-leather reporting, given that politics is an essentially human endeavor and therefore can defy prediction and reason...
But I do not feel today like talking about the anti-empirical reporters--horse-race journamalists who try to avoid learning about horses, tracks, or jockeys--with their alternative methodology of source-flattering. I'm bored with their false and repeatedly disproven claims to magical expertise via choosing and flattering particular sources.
...Asked to comment on Keynes’ famous observation “In the long run we are all dead,” I suggested that Keynes was perhaps indifferent to the long run because he had no children, and that he had no children because he was gay. This was doubly stupid. First, it is obvious that people who do not have children also care about future generations. Second, I had forgotten that Keynes’ wife Lydia miscarried.
This is a book that anyone interested in international economic policy and the possible destinies of the world economy needs to read. Paul Krugman is, as I have said before, the best claimant to the mantle of John Maynard Keynes: an extremely knowledgeable professional economist, an excellent writer, and an incisive critic of what international economic policymakers are doing wrong.

JAMES K. GALBRAITH (University of Texas-Austin) Mainstream economics after the crisis:
My name is Brad DeLong.
I am a Rubinite, a Greenspanist, a neoliberal, a neoclassical economist.
Revised and Extended: I could now talk about the risks of the Trans-Pacific Partnership. You have already heard a lot about the risks in the previous session here. You have heard about dispute resolution and about intellectual property. You have heard about instituting largely-untested dispute resolution procedures in such a way that they will be very difficult indeed to amend or suspend or replace or adjust in the future.
We all know very well the eurozone’s ongoing experience. We remember that the euro single currency is in its origins a geopolitical project. We remember the origins of the eurozone at Maastricht—the decision of the great and good of Europe that something needed to be done to bind Europe more closely together in the wake of the absorption into the Bundesrepublik of the German East and the collapse of the Soviet Empire. The creation of a single currency was clearly something.
Brad DeLong is a professor of economics at UC Berkeley, where his research focuses on financial crises and 20th century macroeconomics, as well as the political economy of monetary and fiscal policy. He has taught at Harvard University and served as Deputy Assistant Secretary of the Treasury for Economic Policy under the Clinton Administration. Below, he and Goldman Sachs Chief Economist Jan Hatzius discuss risks around liftoff and the structural downshift in rates.
Let me back up: Here in the United States, the current framework for macroeconomic policy holds that the economy is nearly normalized, that further extraordinary expansionary and fiscal policy moves carry "risks", and that as a result the right policy is stay-the-course. I was arguing that the Economist Left Opposition demand--for substantially more expansionary monetary and fiscal policies right now until we see the whites of the eyes of rising inflatio--was soundly-based in orthodox lowbrow Hicks-Patinkin-Tobin macro theory. That is the macro theory that economists like Ben Bernanke, Janet Yellen, and Stan Fischer taught their entire academic careers.
Over at Talking Points Memo: The Melting Away of North Atlantic Social Democracy: Hotshot French economist Thomas Piketty, of the Paris School of Economics, looked at the major democracies with North Atlantic coastlines over the past couple of centuries. He saw five striking facts:
First, ownership of private wealth—with its power to command resources, dictate where and how people would work, and shape politics—was always highly concentrated.
Second, 150 years—six generations—ago, the ratio of a country’s total private wealth to its total annual income was about six.
Third, 50 years—two generations—ago, that capital-income ratio was about three.
Fourth, over the past two generations that capital-income ratio has been rising rapidly.
Fifth, the flow of income to the owner of the dollar capital did not rise when capital was relatively scarce, but plodded along at a typical net rate of profit of about 5% per year generation after generation.
He wondered what these facts predicted for the shape of the major North Atlantic economies in the 21st century. And so he wrote a big book, Capital in the Twenty-First Century**READ MOAR at Talking Points Memo
Jack Morton Auditorium, George Washington University :: April 15-16, 2015
It has now been seven years since the onset of the global financial crisis. A central question is how the crisis has changed our view on macroeconomic policy. The IMF originally tackled this issue at a 2011 conference and again at a 2013 conference. Both conferences proved very successful, spawning books titled In the Wake of the Crisis and What Have We Learned? published by the MIT Press.
The time seemed right for another assessment. Research has continued, policies have been tried, and the debate has been intense. How much progress has been made? Are we closer to a new framework? To address these questions the IMF organized a follow up conference on "Rethinking Macro Policy III: Progress or Confusion?", which took place at the Jack Morton Auditorium in George Washington University, Washington DC, on April 15–16, 2015.
The conference was co-organized by IMF Economic Counselor Olivier Blanchard, RBI Governor Raghu Rajan, and Harvard Professors Ken Rogoff and Larry Summers. It brought together leading academics and policymakers from around the globe, as well as representatives from civil society, the private sector, and the media. Attendance was by invitation only.

Olivier Blanchard, when he parachuted me into the panel, asked me to “be provocative.”
So let me provoke:
My assigned focus on “fiscal policy in the medium term” has implications. It requires me to assume that things are or will be true that are not now or may not be true in the future, at least not for the rest of this decade and into the next. It makes sense to distinguish the medium from the short term only if the North Atlantic economies will relatively soon enter a regime in which the economy is not at the zero lower bound on safe nominal interest rates. The medium term is at a horizon at which monetary policy can adequately handle all of the demand-stabilization role.
...and seeing low wage growth as consistent with the view that the productivity slowdown is real.... The unobserved component approach suggests that productivity growth decelerated to an annualized pace of just 0.82 percent by the second quarter of this year... [in line with] Fed staff estimates of potential GDP growth range from roughly 1.6 to 1.8 percent through 2020.... Yellen might think back to the 1990’s, when a surprise rise in productivity growth temporarily lowered the natural rate of unemployment... [and] reverse that logic now and think that the arguments for tighter policy are stronger....
...All pre-industrial societies, I thought, were Malthusian... at the edge of subsistence... [and] a small elite, 5 or 10 percent... liv[ing] on resources extorted.... This model still seems to me to be pretty good for the Roman Empire. But at least as Goldsworthy describes it, the Roman Republic at the time of the Punic Wars was something very different... social solidarity... loyal allies... strong commitment from a large fraction of the population... military manpower... durability.... Are there any other examples in history like this? And how did they do it?

Section 18031 [of the Affordable Care Act--i.e., the ObamaCare Law--] provides that “[e]ach State shall . . . establish an American Health Benefit Exchange..." [But] if [a] State chooses not to do so, Section 18041 provides that the Secretary [of Health and Human Services] “shall . . . establish and operate such Exchange..." (emphasis added [by Roberts]).... The phrase “such Exchange”... instructs the Secretary to establish and operate the same Exchange that the State was directed to establish.... Black’s Law Dictionary 1661... (defining “such” as “That or those; having just been mentioned”).... State Exchanges and Federal Exchanges are equivalent—they must meet the same requirements, perform the same functions, and serve the same purposes...
A simple matter of black-letter law, no? The plain meaning of the phrase "such Exchange" means that anything legal that is true of a health-insurance exchange established by, say, the state of New York is also true of a health-insurance exchange established by the federal government for, say, the state of Florida if the state of Florida fails to establish its exchange, no?
Let me begin by thanking Matt Rognlie for doing some very serious and thoughtful digging into this set of factor-payments data. That digging leaves me in an ideal position for a discussant: There are interesting and important numbers. These numbers have not been put together in this way before. The author is wise enough not to believe he has nailed what the numbers mean to the floor. Thus I am in an excellent position to, if not add intellectual value, at least to claim a lavish intellectual-rent share of Matt Rognlie's product.
At that time--or, rather, in that logical state to which the economy will converge if values of future shocks are set to zero--expected inflation will be constant at about the 2% per year that the Federal Reserve has announced as its target. At that time the short-term safe nominal rate of interest will be equal to that 2% per year of expected inflation, plus the real profits on marginal investments, minus a rate-of-return discount because short-term government bonds are safe and liquid. At that time the money multiplier will be a reasonable and a reasonably stable value. At that time the velocity of money will be a reasonable and a reasonably stable value. Why? Because of the powerful incentive to economize on cash holdings provided by the the sacrifice of several percent per year incurred by keeping cash in your wallet rather than in bonds. And at that time the price level will be proportional to the monetary base. READ MOAR

I want to label something that I see "cognitive capture", and think about it.
The vir illustris Ron Rosenbaum, however, disagrees. Rosenbaum is writing about David Corn's story that Bill O'Reilly was not in fact in a "war zone" in 1982, and about how O'Reilly is responding by saying: "you can tell that I am a truth-teller because the liberals attack me so much". And he thinks that "cognitive capture" is not a useful concept. We should pretend it does not exist. We should instead just tell the truth day by day as if we were having a reasoned discussion. And we should hope that eventually, with enough truth-telling, the chips will fall where they should:
@jayrosen: 1/ To clarify what I meant in saying I share this http://nymag.com/daily/intelligencer/2015/02/fox-news-should-thank-mojo-for-oreilly-story.html view. The @MotherJones story on O'Reilly was still worth doing. It's important to nail down what actually happened, compare that to O'Reilly's statements, and criticize him for misrepresentation. But. Since we're trying to be factual, it is a fact that Fox News is not only built to absorb these blows but to strengthen itself by them. Things are way beyond whether Fox News 'has' or does not 'have' credibility, journalistically. That discourse is surreal at this point. We have to face up to a kind of rupture in the news system. 'Making shit up' is a devastating blow over here, and no big deal over there.. So what I object to is any assumption of 'continuity in credibility.' We need metaphors of discontinuity if we're to understand Fox News.

The policy debate on the sources, causes and potential solutions to rising income and wealth inequality has intensified in the past few years. Recently, French economist Thomas Piketty’s popular book 'Capital in the Twenty-First Century' garnered much attention and ignited further debate about these issues. Piketty argues that wealth will inevitably become more concentrated under capitalism because the returns to wealth are larger than economic growth rates. The solution he proposes is a coordinated global tax on wealth. The Baker Institute's Tax and Expenditure Policy Program will host two renowned economists to discuss the underlying causes and consequences of inequality, evaluate the empirical evidence of rising inequality, and examine potential solutions for dealing with these problems in the United States.

I am very happy to be here, especially as Texas is a state I get to relatively rarely. I have unusually few relatives in it, you see. When the DeLongs got to Wichita they decided to turn north rather than south and wound up in DeKalb County, Illinois. And those who did end up here decamped to North Carolina, leaving me with none until last year when my cousin Annie and her husband moved to Dallas. The last time my wife and I spent any extended time in Texas was on our honeymoon, when we were washed out of our campsite in a swamp near the Louisiana border by a midnight mid-June thunderstorm, so we bypassed Galveston and Houston and then spent a week and a half going Austin-San Antonio-Permian Basin-El Paso.
My problem this morning is that I have four starting points. Or maybe my problem is that I have five starting points:
I. A Little Dutch History
My first starting point is the history of the Netherlands.
I would have to be more rash indeed than the fifteenth century's Charles de Valois-Burgogne,2 the last sovereign Duke of Burgundy, to dare to opine about classical Dutch history with Jan de Vries in the room. But my read of it tells me that "political union" is a very vague and sketchy concept indeed. Consider the "political union" of what was surely the strongest power in seventeenth-century Western Europe: the seven United Provinces of the Netherlands that dominated the economy and were the political-military lynchpin of the coalition to contain the aggressive King Louis XIV Bourbon of France. READ MOAR
Recently, I wrote an article on the role of fiscal policy on economic growth. I argued that, if we want to raise living standards of future generations, a major priority should be reducing the long-term ratio of public debt to GDP. (I also suggested that, since the benefits of higher economic growth disproportionately accrue to high-income households, those households should bear the brunt of the costs of fiscal consolidation.)
In response, Berkeley Economics Professor Brad Delong asked, “Why would anyone seek today to relatively downweight virtually any other economic policy priority in order to focus on the deficit?” At the risk of oversimplifying, Delong offers two classes of reasons for asking his question:
Some questions for the authors of the contributions that struck me as the most interesting...
Two Questions for Scott Sumner: First Question: Why has nominal GDP targeting not already swept the economics community? It really ought to have. Second Question: I believe in nominal GDP targeting--especially if coupled with some version of "social credit" at or near the zero lower bound. But a look back at the history of ideas about a proper "neutral" monetary policy--Newton’s fixed price of gold, Hayek’s fixed nominal GDP level, Fisher’s fixed price-level commodity basket, Friedman’s stable M2 growth rate, the NAIRU targeting of the 1970s, Bernanke’s inflation-targeting—leads immediately to the conclusion that anybody who claims to have uncovered the Philosopher’s Stone here is a madman. How can you reassure me that I (and you) are not mad?
...of the long-run growth rate in the economy.... But it does offer one of the cheapest ways of boosting growth. Unlike fiscal programs such as infrastructure, there is virtually no cost to improving monetary policy.... Elsewhere (2014) I’ve argued that a policy of nominal GDP targeting would smooth out the business cycle and undercut many of the arguments for counterproductive policies.... We need to convince other economists that nominal GDP targeting is the way to go. Once we do so, the Fed will follow the consensus. READ MOAR

**Over at Equitable Growth:As I continue to try to worry--without great success--the question of just where the increases in financial instability produced by the prolonged period of past and expected future extremely low interest rates and by quantitative easing comes from...
Two sources of risk:
Sudden downward revisions in the expected future cash flows of underlying real assets that back financial assets.
Sudden upward revisions in the rate at which expected future cash flows are discounted.
[that] Pimco Total Return had taken its allocation to US Treasury bonds down to zero. As recently as the previous December, Pimco Total Return had been carrying as much as 22 percent of its AUM in Treasurys.... Gross compounded the move by being extremely vocal about his rationale--he went so far as to call Treasury bonds a 'robbery' of investors given their ultra-low interest rates and the potential for inflation. He talked about the need for investors to 'exorcise' US bonds from their portfolios, as though the asset class itself was demonic. He called investors in Treasury bonds 'frogs being cooked alive in a pot'. The rhetoric was every bit as bold as the fund’s positioning. It’s really hard to pound the table like this and then be flexible in the aftermath...
During the past two weeks the drought of high-quality DeLong smackdowns on the internet has resumed. So it is time to turn back to the promise I made myself on April Fools Day 2013, and see whether the rest of the chapters of David Graeber's Debt: The First Five Thousand Mistakes are of as low quality as the utterly bolixed up chapter 12.
As you will recall, David Graeber is infamous for:
Apple Computers is a famous example: it was founded by (mostly Republican) computer engineers who broke from IBM in Silicon Valley in the 1980s, forming little democratic circles of twenty to forty people with their laptops in each other's garages...
and for having, concurrently and subsequently, offered three different explanations of how this howler came to be written and published:
He has claimed that it it all perfectly true, just not of Apple but of other companies (none of which he has ever named).
He has claimed that he had been misled by Richard Wolff, who taught him about Silicon Valley's communal garage laptop circles of the 1980s.
He has claimed that what he had written was coherent and accurate, but that (for some unexplained reason) his editor and publisher had bolixed it all up.
This passage is, in the words of the very sharp LizardBreath:
The Thirteenth Chime... that make[s] me wonder whether any fact in the book I don't know for certain to be true can be trusted...
...The taproot of the trouble is NATO enlargement.... For Putin, the illegal overthrow of Ukraine’s democratically elected and pro-Russian president--which he rightly labeled a “coup”--was the final straw.... Realpolitik remains relevant--and states that ignore it do so at their own peril. U.S. and European leaders blundered in attempting to turn Ukraine into a Western stronghold on Russia’s border....
Soviet leaders... and their Russian successors did not want NATO to grow any larger and assumed that Western diplomats understood their concerns. The Clinton administration evidently thought otherwise.... The first round of enlargement... 1999... the Czech Republic, Hungary, and Poland. The second... 2004... Bulgaria, Estonia, Latvia, Lithuania, Romania, Slovakia, and Slovenia. Moscow complained bitterly.... The alliance considered admitting Georgia and Ukraine.... Putin maintained that admitting those two countries to NATO would represent a “direct threat” to Russia.... READ MOAR
Olivier Blanchard, inveighing against "ergodicity" and "linearity" as assumptions, sounds like some post-Keynesian from the 1980s. They were right then. He is right now:
Olivier Blanchard:Where Danger Lurks: "One has to go back to the so-called rational expectations revolution...
...What was new was the development of techniques to solve models under the assumption that people and firms did the best they could in assessing the future. (A glimpse into why this was technically hard: current decisions by people and firms depend on their whole expected future. But their whole expected future itself depends in part on current decisions.) These techniques... made sense only... [if] economic fluctuations were regular enough so that, by looking at the past, people and firms (and the econometricians)... could understand their nature and form expectations... and simple enough so that small shocks had small effects.... Thinking about macroeconomics was largely shaped by those assumptions....
David Beckworth notes that in the Bernanke-Yellen era the FOMC gets uncomfortable and decides that it has to loosen policy and steps up its interventions when PCE inflation falls below 1.5%/year and gets uneasy and decides that it has to tighten policy when PCE inflation rises above 2%/year:
[This] reduced-form relationship... is highly suggestive and consistent with my claim... that... there is a 2% ceiling to an inflation target corridor...
...where a non-monetary coordination failure has spillover effects, and causes a monetary coordination failure. A worsening of asymmetric information problems in financial markets, which is a coordination problem in its own right, also causes an increased demand for money and a monetary coordination problem. Should we say that the problem in financial markets is the "root cause" of the recession, and one that should be addressed directly, if possible, by something other than monetary policy? No. Monetary policy should take the world as it is, warts and all, and do what it can do. And what it can do is eliminate that excess demand for money, even if it cannot eliminate that original problem that initially caused the excess demand for money. It does not matter, for the monetary authority, whether that increased demand for money was caused by some natural event like the weather, which nobody can change, or whether it was caused by some other problem, which the fiscal authority can and should fix.

Sitting next to Lord Skidelsky in the Sala Maggioranza of the Italian Treasury (after they turned off the air conditioning, I took off my tie when he took off his jacket) impelled me to reread his Keynes biography.
And, after rereading, I find that I cannot improve on what I wrote about them three years ago: my thoughts then were totally enthusiastic and totally adulatory. And my thoughts are the same now. (I haven't yet reread volume three). In his first two volumes, Skidelsky gives us John Maynard Keynes's life, entire. And he does so with wit, charm, control, scope, and enthusiasm. You read these books and you know Keynes--who he was, what he did, and why it was so important.
Let's start with Paul Krugman, who made me aware of this ebook by writing:
Paul Krugman:All About Zero: "Way back in 2008 I (and many others) argued...
...that the financial crisis had pushed us into a liquidity trap... in which the Fed and its counterparts elsewhere couldn’t restore full employment even by reducing short-term interest rates all the way to zero.... In practice the zero lower bound has huge adverse effects on policy effectiveness... [and] drastically changes the rules... [as] virtue becomes vice and prudence is folly. We want less saving, higher expected inflation, and more.... Liquidity-trap analysis has been overwhelmingly successful in its predictions: massive deficits didn’t drive up interest rates, enormous increases in the monetary base didn’t cause inflation, and fiscal austerity was associated with large declines in output and employment....

UPDATE: As Noah Smith politely points out, I did a no-no in being so lazy as to take averages of monthly returns to be "close enough" to cumulative compounded returns. Fixing that requires some edits, which I have made:
...is hovering at a worrisome level.... Above 25, a level that has been surpassed... in only... the years clustered around 1929, 1999 and 2007. Major market drops followed those peaks.... We should recognize that we are in an unusual period, and that it’s time to ask some serious questions about it...
The first question I think we should ask is: how damaging in the long run to investor portfolios were the major market drops that followed the 1929, 1999, and 2007 CAPE peaks? The CAPE is the current price of the S&P index divided by a ten-year trailing moving average of its earnings: the CAPE looks back ten years to try to get an estimate of what normal earnings are and how stock prices deviate from them. Let's look ahead and calculate ten-year forward earnings to get a sense of what signals the CAPE sends for those of us interested in stocks for the long run. When we do that, we find that we cannot calculate a ten-year return for the 2007 CAPE peak of 27.54--we still have three years to go. But over the past seven years the S&P has produced an average annual real return of 5.2%/year: not too shabby. The ten-year average real return from the 1929 peak of 32.56 was 3.3%/year: you were in a real world of hurt if you panicked and sold or had to sell in 1931-1934, but not if you hung on. Only the 1999 peak was followed by long-run return disaster: a ten-year average real return of -2.1%/year because you would have been selling at the bottom in 2009--but even then if you had hung on until today your average 14.5 year real return would be +2.7%/year.
The first current is the Adam Smith current, which makes the classical liberal bid: Smith claims that the system of natural liberty; with government restricted to the rule of law, infrastructure, defense, and education; is the best of all social arrangements.
This first current is then joined by the Karl Polanyi current: Polanyi says that, empirically, at least in the Industrial Age, the system of natural liberty fails to produce a good-enough society. The system of natural liberty turns land, labor, and finance into commodities. The market then moves them about the board in its typically disruptive fashion: "all that is solid melts into air", or perhaps "established and inherited social orders are steamed away". But land, finance, and labor--these three are not real commodities. They are, rather, "fictitious commodities", for nobody wants their ability to earn a living, or to live where they grew up, or to start a business to be subject to the disruptive wheel of market fortuna.

Of all the weird things that have happened in the American public sphere in my life, the most weird was the War on Nate Silver--launched in the fall of 2012 by David Brooks, Joe Scarborough, Dylan Byers, and a remarkably large company.
The underlying argument appeared to be that Nate Silver was doing something wrong and unfair by using... evidence. By... counting things. By... using statistics. By... estimating probabilities...
What I hate are the forecasts, when they say so and so has a 66 percent chance of winning or a 32 percent chance of winning.... If you tell me you think you can quantify an event that is about to happen that you don’t expect, like the 47 percent comment or a debate performance, I think you think you are a wizard. That’s not possible...
I have said this before. But I seem to need to say it again...
The very intelligent and thoughtful David Beckworth, Simon Wren-Lewis, and Nick Rowe are agreeing on New Keynesian-Market Monetarist monetary-fiscal convergence. Underpinning all of their analyses there seems to me to be the assumption that all aggregate demand shortfalls spring from the same deep market failures. And I think that that is wrong.
Simon Wren-Lewis writes:
I really like David Beckworth’s Insurance proposal against ‘incompetent’ monetary policy. Here it is: 1) Target the level of nominal GDP (NGDP). 2) "The Fed and Treasury... agree... should a liquidity trap emerge anyhow... quickly work together to implement a helicopter drop...." Market Monetarists and New Keynesians [do not] suddenly agree about everything... for David this is an insurance against incompetence by the central bank, whereas Keynesians... view hitting the ZLB as unavoidable if the shock is big enough. However this difference is not critical...
Paul Krugman admonishes me for thinking I should try to work out what model underlies the Bank for International Settlements' 84th Annual Report. It is, he says, not so much a macroeconomic model or an analytical framework. Rather, he says, it is a mood: the rhetorical stance of austerity a outrance:
...who warned against any 'artificial stimulus' that might leave the 'work of depressions undone'. And in 2010-2011 it had an intellectually coherent--actually wrong, but coherent--story... that mass unemployment was the result of structural mismatch... [and] easy money would lead to a rapid rise in inflation.... it didn’t happen. So... it... look[ed] for new justifications for the same [policy] prescriptions... playing up the supposed damage low rates do to financial stability.... That over-indebtedness on the part of part of the private sector is exerting a persistent drag on the economy... is a reasonable story.... But the BIS... doesn’t understand that model... as if they were equivalent to... real structural problems... [which] makes a compelling case for... fiscal deficits to support demand while the private sector gets its balance sheets in order, for monetary policy to support the fiscal policy, for a rise in inflation targets both to encourage whoever isn’t debt-constrained to spend more and to erode the real value of the debt. The BIS, however, wants governments as well as households to retrench... and--in a clear sign that it isn’t being coherent--it includes a box declaring that deflation isn’t so bad, after all. Irving Fisher wept....
Are the BIS’s methods unsound? I don’t see any method at all. Instead, I see an attitude, looking for justification...
