the optimal social extractor mechanisms must do a lot better then the present heterogenious array of interest payment paths contractual obligations suffer from the incidentals of the march of transactional events

we need a big intricate extractor re set system

do quasi rents dissolve optimally in a unregulated market system ?

lets doubt that eh ?


so what task comes into view  ?

gos plan 2.0
incorporating this reality
 into the design and  construction   of the hover craft full of    tax and subsidy algorithms

a fools dream ? ramseying away all economic rents

interest as a time and contract variable tax on capital

in part real in part notional

not necessarily < then operating profit

a tax
  notionally different from its real extraction by actual creditors

the  implicit  equally notional
 non price and quantity governing
 point of systemic steady state 
has a general rate of interest
      that  zeros out all operating profits

this is the goal
of any gosplan 2.0

  a " general system wide tax " on  "capital"

 

implemented thru the total credit funding system
                                               like this general rate of interest

most published findings are trash...

Let’s start with Ioannidis. As the title suggests, the paper claims that many published results are false. This is not surprising to most statisticians and epidemiologists. Nevertheless, the paper has received much attention. Let’s suppose, as Ioannidis does, that “publishing a finding” is synonymous with “doing a test and finding that it is significant.” There are many reasons why published papers might have false findings. Among them are:
  1. From elementary probability
    \displaystyle  P(false\ positive|paper\ published) \neq P(false\ positive|null\ hypothesis\ true).
    In fact, the left hand side can be much larger than the right hand side but it is the quantity on the right hand side that we control with hypothesis testing.
  2. Bias. There are many biases in studies so even if the null hypothesis is true, the p-value will not have a Uniform (0,1) distribution. This leads to extra false rejections. There are too many sources of potential bias to list but common ones include: unobserved confounding variables and the tendency to only report studies with small p-values.
These facts are well-known, thus I was surprised that the paper received so much attention. All good epidemiologists know these things and they regard published findings with suitable caution. So, to me, this seems like much ado about nothing. Published findings are considered “suggestions of things to look into,” not “definitive final results.” Nor is this a condemnation of significance testing which is just a tool and, like all tools, should be properly understood. If a fool smashes his finger with a hammer we don’t condemn hammers. (The problem, if there is one, is not testing, but the press, who do report every study as if some definitive truth has been uncovered. But that’s a different story.)
Let me be clear about this: I am not suggesting we should treat every scientific problem as if it is a hypothesis testing problem. And if you have reason to include prior information into an analysis then by all means do so. But unless you have magic powers, simply doing a Bayesian analysis isn’t going to solve the problems above.
Let’s compute the probability of a false finding given that a paper is published. To do so, we will make numerous simplifying assumptions. Imagine we have a stream of studies. In each study, there are only two hypotheses, the null {H_0} and the alternative {H_1}. In some fraction {\pi} of the studies, {H_0} is true. Let {A} be the event that a study gets published. We do hypothesis testing and we publish just when we reject {H_0} at level {\alpha}. Assume further that every test has the same power {1-\beta}. Then the fraction of published studies with false findings is
\displaystyle  P(H_0|A) = \frac{P(A|H_0)P(H_0)}{P(A|H_0)P(H_0) + P(A|H_1)P(H_1)} = \frac{ \alpha \pi}{ \alpha \pi + (1-\beta)(1-\pi)}.
It’s clear that {P(H_0|A)} can be quite different from {\alpha}. We could recover {P(H_0|A)} if we knew {\pi}; but we don’t know {\pi} and just inserting your own subjective guess isn’t much help. And once we remove all the simplifying assumptions, it becomes much more complicated. But this is beside the point because the bigger issue is bias.
The bias problem is indeed serious. It infects any analysis you might do: tests, confidence intervals, Bayesian inference, or whatever your favorite method is. Bias transcends arguments about the choice of statistical methods.
Which brings me to Madigan. David Madigan and his co-workers have spent years doing sensitivity analyses on observational studies. This has been a huge effort involving many people and a lot of work.
They considered numerous studies and asked: what happens if we tweak the database, the study design, etc.? The results, although not surprising, are disturbing. The estimates of the effects vary wildly. And this only accounts for a small amount of the biases that can enter a study.
I do not have links to David’s papers (most are still in review) so I can’t show you all the pictures but here is one screenshot:
Madigan
Each horizontal line is one study; the dots show how the estimates change as one design variable is tweaked. This picture is just the tip of the iceberg. (It would be interesting to see if the type of sensitivity analysis proposed by Paul Rosenbaum is able to reveal the sensitivity of studies but it’s not clear if that will do the job.)
To summarize: many published findings are indeed false. But don’t blame this on significance testing, frequentist inference or incompetent epidemiologists. If anything, it is bias. But really, it is simply a fact. The cure is to educate people (and especially the press) that just because a finding is published doesn’t mean it’s true. And I think that the sensitivity analysis being developed by David Madigan and his colleagues will turn out to be essential.

residential sales ratio existing to new

"Why do we have business cycles? Why do asset prices move around so much? At this stage, macroeconomics has little to offer by way of answer to these questions…. The sources of disturbances in macroeconomic models are (to my taste) patently unrealistic. Perhaps most famously, most models in macroeconomics rely on some form of large quarterly movements in the technological frontier… collective shocks to the marginal utility of leisure… large quarterly shocks to the depreciation rate in the capital stock…. None of these disturbances seem compelling, to put it mildly…."

kon kon lakota

"An especially pretentious conceit of the modern macroeconomics of the last 40 years is that the extreme assumptions on which it rests are the essential microfoundations without which macroeconomics lacks any scientific standing. That’s preposterous. Perfect foresight and rational expectations are assumptions required for finding the solution to a system of equations describing a general equilibrium. They are not essential properties of a system consistent with the basic rationality propositions of microeconomics"

Shii Kazuo on global trans nat inc's" trade pact power play"

"The JCP chair demanded that the government give up participating in negotiations for the Trans-Pacific Partnership (TPP) agreement, stating that an entry into the free-trade pact would deal a devastating blow to Japan's agriculture and sell out the nation's sovereignty over medical care, employment, and food safety to the United States.

He criticized Prime Minister Noda Yoshihiko's pledge in his policy speech to "promote the TPP while protecting what should be protected." Stressing that "removal of tariffs without exceptions" and "elimination of non-tariff barriers" are the fundamental principles of the TPP, Shii asked what Noda considers as "items that should be protected."

In response to Shii, the prime minister only stated that he is determined to protect "Japan's medical system, Japanese traditions and culture, and beautiful farm villages.""

" "The Japan-U.S. Security Treaty is the root cause of Japan's subordination to the U.S. The government should abrogate the treaty and conclude a treaty of friendship with the U.S.""

brad self ex culpation



see back in 92 we were right  to

"...aggressively move to reduce the budget deficit in 1993 even thought the recovery was weak"

ya break a huge party redefining campaign pledge

 to cut working family federal taxes ,,...


why brekl that pledge p ass NAFTA and lose the house in 94 ?


" to eliminate any market expectations
that high deficits would lead to higher inflation"


okay nonsense but okay ...
excpt brad doesn't really believe the market is the prime mover here

attendez vour to  the nut cutter  line

..."--more importantly--"

meaning in reality


"to eliminate any belief
on the part of the Federal Reserve
that it need to raise rates rapidly and far "
i repeat
that " more importantly"
 is brad telling us
the FED is decisive in such a context

and the FED must be appeased


or  the FED
by strangling the recovery in a credit crunch
would create
 "... a low-investment jobless recovery "

and why would the FED dosuch a nasty thing ?

"in order to guard against any possibility
of a renewed inflationary spiral."


but brad
 was there any basis for such a concern ?
an inflationary spiral ? ...come now
isn't that just what a weak recovery won't create ?

in particular
an inflationary spiral
so fierce it required over the horizon
pre emption ?

of course not


now check out this pusilanimous crap


"That was not an attack"
(of bond vigilantes)
   but it was

" a horizon-sighting of bond-market vigilantes--"

or was it ?

if he had the cubes to stop there its one thing
but here he goes covering his crotch

".. perhaps only the market thinking the Federal Reserve thought it was about to get a horizon-sighting of bond market vigilantes."
no you guysin the  white house basement
thinking the market might be thinking the federal reserve might be thinking..blah blah blah

enough ?
nope
now don't he ned to  double down


"I think we were right then to fear and take steps to ward off the bond-market vigilantes"

really ?

eerrrr 
" or perhaps"


" only right
 to fear and take steps to ward off
any Federal Reserve decision
that it needed to fear and take steps
to deal with bond-market vigilantes."

amazing !

brad alibis  bondage bob rubin crap
 by fingering a trigger happy greenspan  FED

beautiful
what a fudge fest











"First, what was going on in 1994--and what those of us working in the Treasury and watching the Federal Reserve and the financial markets thought was going on--was not an attack of bond-market vigilantes terrified of rising debt and the prospect of explicit default or implicit default through rapid inflation. The Federal Reserve had undertaken a long easing from 1990 through the mid-1992 unemployment rate peak. But then, as unemployment started to decline, the Federal Reserve held off on tightening: it was expecting the passage of the deficit-reducing Clinton 1993 Reconciliation Bill--OBRA 19930--and believed that the spending cuts and tax increases in that were sufficient. In early 1994, however, the Federal Reserve concluded that it was time for monetary tightening, and began to gradually raise short-term safe interest rates by selling off some of its bonds for cash.
We in the Treasury--and the staff at the Federal Reserve--had expected the reaction of the long-term bond market to this Fed tightening cycle to be modest. Between 1990 and 1994 the Federal Reserve had reduced short-term interest rates by 5%, and as it had done so long-term rates had fallen by 3%. We attributed 1.75% of that long-term interest rate reduction to the reduced current and expected future federal deficits as a result of Clinton's OBRA 1993 and the earlier Foley-Mitchell-Bush OBRA 1990, leaving 1.25% to be the reaction of the long-term bond market to lower short-term interest rates. Thus as the Federal Reserve raised short-term safe interest rates from 3% to 6%, we expected a quarter of that to show up as a rise in long-term rates--we expected to see them go from 6% to 6.75%.
Instead, in 1994 long-term bond rates rose from 6% to 8%.
In the end we attributed the excess rise in long-term bond rates in 1994 to two factors:
  1. As interest rates rose, the duration of Mortgage Backed Securities lengthened--people weren't refinancing their houses any more. MBS thus became much longer duration securities--there was a much greater supply of long-term bonds in the market--and by supply and demand that pushed the prices of such bonds down until investment banks could figure out how to tap more risk-bearing capacity to hold those bonds.
  2. Nobody was sure that the Federal Reserve was going to stop raising short-term safe interest rates when they hit 6%. In the late 1980s, after all, they had not stopped until short-term interest rates hit 8%. Without effective forward guidance from the Federal Reserve, the bond market was pricing in a larger tightening than seemed likely to us.
FRED Graph  St Louis Fed 5
We were, I think, completely correct. By mid-1995 it was clear that the Federal Reserve had reached the end of its tightening cycle and more money had flowed into the long-term bond market to hold attractively-priced MBS, and the long bond rate fell back into the trading range we had anticipated--and then fell some more.
So: 1994 was an interesting lesson on the importance of clear Federal Reserve forward guidance in avoiding excess bond-market volatility and on the consequences of endogenous duration for the short-term pricing of complex securities, but it was not an example of bond-market vigilantes fearing higher deficits and default or inflation riding over the horizon. The federal deficit was under control and rapidly shrinking in 1994 as the combination of the business-cycle recovery and Clinton's OBRA 1993 worked even better than we had anticipated.
Second, there had been an attack--or, rather, not an attack but rather bond-market vigilantes visible on the horizon and gunshots in the air--earlier.
Throughout 1992 there was a 4%-point gap between the 3-Month Treasury rate and the 10-Year Treasury rate. Those of us in the Clinton-administration-to-be read this as market expectations that the uncontrolled federal budget deficit would lead people to expect higher inflation and the Federal Reserve would then feel itself forced to raise short-term interest rates far and fast in order to hit the economy on the head with a brick and keep those expectations of higher inflation from coming true. The result would be a low-investment and perhaps a jobless recovery. The right policy, we thought--and I think the evidence is pretty clear that we were 100% right--was to aggressively move to reduce the budget deficit in 1993 even thought the recovery was weak in order to eliminate any market expectations that high deficits would lead to higher inflation, and--more importantly--to eliminate any belief on the part of the Federal Reserve that it need to raise rates rapidly and far to create a low-investment jobless recovery in order to guard against any possibility of a renewed inflationary spiral.
That was not an attack but a horizon-sighting of bond-market vigilantes--or perhaps only the market thinking the Federal Reserve thought it was about to get a horizon-sighting of bond market vigilantes.
I think we were right then to fear and take steps to ward off the bond-market vigilantes--or perhaps only right to fear and take steps to ward off any Federal Reserve decision that it needed to fear and take steps to deal with bond-market vigilantes. In any event, our policies were right.
But that was then, with a 4%-point gap between 10-Yr and 3-Mo Treasury yields

Today we only have a 1.6%-point gap between 10-Yr and 3-Mo Treasury yields.
1.6% < 4%"

lucas only calls it fiscal activism if the fed sits on its hands


crowding out if assumed to be very powerful ...

u get it

fiscal policy can be largely self nullifying 
even if the borrowed funds get spent completely
if the credit markets off set any additional uncle borrowing
by reducing firm and or household borrowing by an equivalent amount

one way this gets  turned into a nice trick

the impact of uncle on the credit markets raises rates
and by pre aexisting harmonics
the  rate elasticity of firm and household borrowing is such as to exactly off set the increased borrow by uncle
with reduced borrowing by the F's and H's

but the broader point is to introduce doubt
doubt  in the efficacy of the additional uncle spending
a doubt that arms itself
  with  visions of large countering contractions
 in  F  and H spending out of  net new borrowings
such it is hoped will pre emptively  scuttled
any fiscal activism

uncle borrowings crowding out private borrowings

recipients
  of net increased transfer payments
 or new  tax cuts
  won't spend  the additional funds
   buying additional recent  outputs  of the production system


reactive firm pricing will render it all nominal

welcome to the  stump  list

 all about stumping fiscal activism

would lucas call a counter cyclical "earned social didivend" system monetary policy ?

i guess if the program was explicitly monetized

maybe the fed directly bought the issued ear marked debt
it would look like  just " a   fairness just desserts regulated"
           fed  helicopter drop

but of course the FOMC
 can off set or accomodated  any net new issue by the treasury
 simply by
  a purchasing program or selling program
of any  t issued paper
that the fed deems  roughly equivalent



 

     or ....you know ...whatever !

PK on NK

"So, Noah Smith weighs in on the state of macro and argues that there really isn’t that much disagreement in the field, because both saltwater and freshwater macro use the same set of techniques."


 "...New Keynesians .. still find  Keynesian ideas useful and argues that monetary and fiscal policy can be effective;
 real business cyclist ....business cycles are optimal responses to real shocks "


". Alchemists and chemists used similar equipment: retorts, beakers, and so on. ....
. New Keynesians and real business cycle theorists both do lots of intertemporal maximization
. Again, this doesn’t make them the same endeavor."


"The real test came when the financial crisis struck"

".. pretty much to a man freshwater economists not only argued against fiscal stimulus — which is a defensible position — but insisted that there was no possible way to justify stimulus,"


".. such ideas had been refuted and that “nobody” believed in them anymore."


 "anyone who actually worked with an NK  model would know that fiscal policy
 can indeed have an effect in that framework."


"I’m not saying that the NK approach is necessarily right;.....there’s a lot of evidence for the price stickiness that is central to NK models;"

"... maybe  that evidence doesn’t mean what the theorists think, but surely that evidence ought to be part of any discussion."


"So yes, the equations in one of Mike Woodford’s papers look a lot like the equations coming out of Chicago or Minneapolis."

" And a few years ago it was possible to delude oneself into believing that this represented a true convergence of thought. But recent events have proved that it just wasn’t true"

.".. To be sure, the upswing in house prices in many markets around the country in the 2000s did reach levels that history and the subsequent long downswings tell us were excessive. But, as we show in Part II, such excessive fluctuations should not be interpreted to mean that asset-price swings are unrelated to fundamental factors. In fact, even if an individual is interested only in short-term returns—a feature of much trading in many markets—the use of data on fundamental factors to forecast these returns is extremely valuable. And the evidence that news concerning a wide array of fundamentals plays a key role in driving asset-price swings is overwhelming.[16]
Missing the Point in the Economists’ Debate
Economists concluded that fundamentals do not matter for asset-price movements because they could not find one overarching relationship that could account for long swings in asset prices. The constraint that economists should consider only fully predetermined accounts of outcomes has led many to presume that some or all participants are irrational, in the sense that they ignore fundamentals altogether. Their decisions are thought to be driven purely by psychological considerations.
The belief in the scientific stature of fully predetermined models, and in the adequacy of the Rational Expectations Hypothesis to portray how rational individuals think about the future, extends well beyond asset markets. Some economists go as far as to argue that the logical consistency that obtains when this hypothesis is imposed in fully predetermined models is a precondition of the ability of economic analysis to portray rationality and truth.
For example, in a well-known article published in The New York Times Magazinein September 2009, Paul Krugman (2009, p. 36) argued that Chicago-school free-market theorists “mistook beauty . . . for truth.” One of the leading Chicago economists, John Cochrane (2009, p. 4), responded that “logical consistency and plausible foundations are indeed ‘beautiful’ but to me they are also basic preconditions for ‘truth.’” Of course, what Cochrane meant by plausible foundations were fully predetermined Rational Expectations models. But, given the fundamental flaws of fully predetermined models, focusing on their logical consistency or inconsistency, let alone that of the Rational Expectations Hypothesis itself, can hardly be considered relevant to a discussion of the basic preconditions for truth in economic analysis, whatever “truth” might mean.
There is an irony in the debate between Krugman and Cochrane. Although the New Keynesian and behavioral models, which Krugman favors,[11] differ in terms of their specific assumptions, they are every bit as mechanical as those of the Chicago orthodoxy. Moreover, these approaches presume that the Rational Expectations Hypothesis provides the standard by which to define rationality and irrationality.[18]
Behavioral economics provides a case in point. After uncovering massive evidence that the contemporary economics’ standard of rationality fails to capture adequately how individuals actually make decisions, the only sensible conclusion to draw was that this standard was utterly wrong. Instead, behavioral economists, applying a variant of Brecht’s dictum, concluded that individuals are irrational.[19]
To justify that conclusion, behavioral economists and nonacademic commentators argued that the standard of rationality based on the Rational Expectations Hypothesis works—but only for truly intelligent investors. Most individuals lack the abilities needed to understand the future and correctly compute the consequences of their decisions.[20]
In fact, the Rational Expectations Hypothesis requires no assumptions about the intelligence of market participants whatsoever (for further discussion, see Chapters 3 and 4). Rather than imputing superhuman cognitive and computational abilities to individuals, the hypothesis presumes just the opposite: market participants forgo using whatever cognitive abilities they do have. The Rational Expectations Hypothesis supposes that individuals do not engage actively and creatively in revising the way they think about the future. Instead, they are presumed to adhere steadfastly to a single mechanical forecasting strategy at all times and in all circumstances. Thus, contrary to widespread belief, in the context of real-world markets, the Rational Expectations Hypothesis has no connection to how even minimally reasonable profit-seeking individuals forecast the future in real-world markets. When new relationships begin driving asset prices, they supposedly look the other way, and thus either abjure profit-seeking behavior altogether or forgo profit opportunities that are in plain sight.
The Distorted Language of Economic Discourse
It is often remarked that the problem with economics is its reliance on mathematical apparatus. But our criticism is not focused on economists’ use of mathematics. Instead, we criticize contemporary portrayal of the market economy as a mechanical system. Its scientific pretense and the claim that its conclusions follow as a matter of straightforward logic have made informed public discussion of various policy options almost impossible.
Doubters have often been made to seem as unreasonable as those who deny the theory of evolution or that the earth is round. Indeed, public debate is further distorted by the fact that economists formalize notions like “rationality” or “rational markets” in ways that have little or no connection to how non-economists understand these terms. When economists invoke rationality to present or legitimize their public-policy recommendations, non-economists interpret such statements as implying reasonable behavior by real people. In fact, as we discuss extensively in this book, economists’ formalization of rationality portrays obviously irrational behavior in the context of real-world markets.
Such inversions of meaning have had a profound impact on the development of economics itself. For example, having embraced the fully predetermined notion of rationality, behavioral economists proceeded to search for reasons, mostly in psychological research and brain studies, to explain why individual behavior is so grossly inconsistent with that notion—a notion that had no connection with reasonable real-world behavior in the first place.
Moreover, as we shall see, the idea that economists can provide an overarching account of markets, which has given rise to fully predetermined rationality, misses what markets really do. ...
Footnotes
16 See Chapters 7-9 for an extensive discussion of the role of fundamentals in driving price swings in asset markets and their interactions with psychological factors.
17 For example, in discussing the importance of the connection between the financial system and the wider economy for understanding the crisis and thinking about reform, Krugman endorses the approach taken by Bernanke and Gertler. (For an overview of these models, see Bernanke et al., 1999.) However, as pioneering as these models are in incorporating the financial sector into macroeconomics, they are fully predetermined and based on the Rational Expectations Hypothesis. As such, they suffer from the same fundamental flaws that plague other contemporary models. When used to analyze policy options, these models presume not only that the effects of contemplated policies can be fully pre-specified by a policymaker, but also that nothing else genuinely new will ever happen. Supposedly, market participants respond to policy changes according to the REH-based forecasting rules. See footnote 3 in the Introduction and Chapter 2 for further discussion.
18 The convergence in contemporary macroeconomics has become so striking that by now the leading advocates of both the “freshwater” New Classical approach and the “saltwater” New Keynesian approach, regardless of their other differences, extol the virtues of using the Rational Expectations Hypothesis in constructing contemporary models. See Prescott (2006) and Blanchard (2009). It is also widely believed that reliance on the Rational Expectations Hypothesis makes New Keynesian models particularly useful for policy analysis by central banks. See footnote 7 in this chapter and Sims (2010). For further discussion, see Frydman and Goldberg (2008).
19 Following the East German government’s brutal repression of a worker uprising in 1953, Bertolt Brecht famously remarked, “Wouldn’t it be easier to dissolve the people and elect another in their place?”
20 Even Simon (1971), a forceful early critic of economists’ notion of rationality, regarded it as an appropriate standard of decision-making, though he believed that it was unattainable for most people for various cognitive and other reasons. To underscore this view, he coined the term “bounded rationality” to refer to departures from the supposedly normative benchmark."

 "we develop a simple model of economic growth in a world in which all countries benefit and potentially contribute to advances in the world technology frontier. A greater gap of incomes between successful and unsuccessful entrepreneurs (thus greater inequality) increases entrepreneurial effort and hence a country’s contribution to the world technology frontier"




and get this


"We show that, under plausible assumptions, the world equilibrium is asymmetric: some countries will opt for a type of “cutthroat” capitalism that generates greater inequality and more innovation and will become the technology leaders, while others will free-ride on the cutthroat incentives of the leaders and choose a more cuddly form of capitalism. Paradoxically, those with cuddly reward structures, though poorer, may have higher welfare than cutthroat capitalists; but in the world equilibrium, it is not a best response for the cutthroat capitalists to switch to a more cuddly form of capitalism. We also show that domestic constraints from social democratic parties or unions may be beneficial for a country because they prevent cutthroat capitalism domestically, instead inducing other countries to play this role.
