More Rationale for Overoptimism
The observer’s beliefs are different from agent A’s. They are drawn from the same distribution G but there is no reason that the observer’s beliefs are the same as agent A’s. In fact, the action agent A took will only be the best one from the observer’s perspective by accident. Actually, the observer’s beliefs will be the average of the distribution G which is lower than the belief of agent A since agent A deliberately took the action which he thought was the best. This implies that the agent A who took the action is “overoptimistic” relative to an arbitrary observer.

Contrarian Spurrious Correlation of the Day

Salience and Taxes
Anyway, I don't mind taxes. I think if I knew what I was paying and knew what I was left with at the end, and had to think less about "this part goes to tax" I probably wouldn't mind the taxes so much, and it wouldn't mess with my consumption choices as much. This is one thing that's always puzzled me about sales taxes here in the US. Why can't they just be included in the price? Why does something priced at a dollar have to come out to $1.06 or something?
This is also probably why we don't think too much about tariffs on imports. We never see how it impacts the prices, so we almost just assume that we're not really "paying" any of the burden (which of course is patently false). This might mean that the consumption distortions from trade restrictions are not as high, but it might mean that the production distortions are even higher.

Green Jobs are More than Broken windows
Have you ever witnessed the anger of the good shopkeeper, James Goodfellow, when his careless son happened to break a pane of glass? If you have been present at such a scene, you will most assuredly bear witness to the fact, that every one of the spectators, were there even thirty of them, by common consent apparently, offered the unfortunate owner this invariable consolation—"It is an ill wind that blows nobody good. Everybody must live, and what would become of the glaziers if panes of glass were never broken?"
Now, this form of condolence contains an entire theory, which it will be well to show up in this simple case, seeing that it is precisely the same as that which, unhappily, regulates the greater part of our economical institutions.
Suppose it cost six francs to repair the damage, and you say that the accident brings six francs to the glazier's trade—that it encourages that trade to the amount of six francs—I grant it; I have not a word to say against it; you reason justly. The glazier comes, performs his task, receives his six francs, rubs his hands, and, in his heart, blesses the careless child. All this is that which is seen.
But if, on the other hand, you come to the conclusion, as is too often the case, that it is a good thing to break windows, that it causes money to circulate, and that the encouragement of industry in general will be the result of it, you will oblige me to call out, "Stop there! Your theory is confined to that which is seen; it takes no account of that which is not seen."
It is not seen that as our shopkeeper has spent six francs upon one thing, he cannot spend them upon another. It is not seen that if he had not had a window to replace, he would, perhaps, have replaced his old shoes, or added another book to his library. In short, he would have employed his six francs in some way, which this accident has prevented.
It seems that the comparison of using stimulus dollars for green investments to broken windows is akin to making a type III error: giving the right answer to the wrong question. No, green investments by the public sector will not increase the long-run number of jobs, and they may have some unintended consequences if future harm is not priced with a tax or an auction. However, short-term public sector jobs will reduce the pain of the current recession by reducing overall employment in the short term. Then the question is what the best thing to do is, i.e. "are green jobs better than the next best alternative for public funds?" To many the answer is "yes." Investments made now to clean up the environment and improve our energy infrastructure will do a lot to increase welfare even if that welfare is not well measured by the metrics of GDP and employment. The "broken windows" analogy also frames the debate in a misleading way. If the analogy is apt, then it must be the case that the "windows" are already "broken" and the cleanup investments are just paying the tab for the vandalism of past generations.

Sad Commentary
Last year, the U.S. Justice Department began investigating whether VMI's environment is especially hostile to women. Allegations of sexual assault have become a fact of VMI life, occurring about once a year, typical for a school of this size, according to college officials. The first case to result in a criminal charge ended Tuesday.That means they guy could have easily been convicted, but instead got a suspended sentence, meaning he will not serve a day for rape. Probably happens all the time all across the country, and that is a sad commentary on our society.In that case, a female cadet alleged that Stephen J. Lloyd, then a senior from Mason Neck, Va., pulled her into a storage room the night of March 27 and raped her. Lloyd no longer attends VMI. On Tuesday, he entered an Alford plea, which means he did not admit guilt but acknowledged that there is enough evidence to convict him. The plea is tantamount to a conviction of misdemeanor sexual battery.
The sentence: a year in jail and a $2,500 fine, suspended.

Lurking Variables and Statistical Literacy
Economix explains why:
In 2008, only 14 percent of federal workers were on part-time schedules, compared to 26 percent in the private sector. Federal workers were far older on average: 55 percent were between the ages of 45 and 64, compared to 36 percent of private-sector workers. Furthermore, 45 percent of federal workers held a college degree or higher educational credential, compared to 29 percent of private-sector workers.and
analysis of the impact of individual education and experience on earnings in the United States by the Harvard economist George Borjas showed that federal employees are paid considerably less than comparable private workers at the top end.Basically, people looking at the simple averages are not accounting for several important ("lurking") variables that more than explain the average differentials between federal employees and the average private-sector employee. Andrew Gelman calls this a lack of "statistical literacy"; some call it "lying with statistics". These statistical liars include Chris Edwards at Cato (who by the way should probably know better but is advancing a deliberate agenda), The Free Enterprise Nation, Ilana Mercer of World Net Daily, and Jeff Jacoby of The Boston Globe.

impressed that economics is not really fundamentally about markets, but
about resource allocation and distribution problems. Markets appear
because they operate effectively to handle a subset of these resource allocation
challenges. ” - Michael Spence, senior fellow, the Hoover Institution.

Protons, Prostate Cancer, and Bad Incentives in Health Care
I'm still puzzled by the blind faith we put in doctors when it comes to their motives in recommending treatment. Doctors, like mechanics, have an incentive to "run up the bill" even to the point of making s--- up or recommending treatments (repairs) that may or may not be necessary. We should WANT a bureaucrat that knows something about the effectiveness of treatments between us and our doctors, whether it's a government bureaucrat or a private sector one! Problem now is that the private sector bureaucrat has perverse incentives, too. A little regulation in these cases (or a public provider) could go a long way.

The Downside of a Global Supply Chain
Ground beef is usually not simply a chunk of meat run through a grinder. Instead, records and interviews show, a single portion of hamburger meat is often an amalgam of various grades of meat from different parts of cows and even from different slaughterhouses.... The frozen hamburgers made by the food giant Cargill, were labeled “American Chef’s Selection Angus Beef Patties.” Yet confidential grinding logs and other Cargill records show that the hamburgers were made from a mix of slaughterhouse trimmings and a mash-like product derived from scraps that were ground together at a plant in Wisconsin. The ingredients came from slaughterhouses in Nebraska, Texas and Uruguay, and from a South Dakota company... Those low-grade ingredients are cut from areas of the cow that are more likely to have had contact with feces, which carries E. coli, industry research shows. Yet Cargill, like most meat companies, relies on its suppliers to check for the bacteria and does its own testing only after the ingredients are ground together.

"Locavorism" and the Environment
...lamb raised on New Zealand’s clover-choked pastures and shipped 11,000 miles by boat to Britain produced 1,520 pounds of carbon dioxide emissions per ton while British lamb produced 6,280 pounds of carbon dioxide per ton, in part because poorer British pastures force farmers to use feed. In other words, it is four times more energy-efficient for Londoners to buy lamb imported from the other side of the world than to buy it from a producer in their backyard.Nor is knowing the producer necessarily good for the community:
Historically, such personalized economic transactions were the norm, but they were inherently fraught with risk and tension. In colonial America — a place I’ve studied in some depth — all markets were initially driven by face-to-face interaction. It should come as no surprise that things could get, well, personal. Markets were intensely competitive and exclusive. Everyone knew everyone. And that was often the problem. The court records of colonial New England are replete with personal market transactions gone awry.Food for thought, so to speak. Trade is good.

Bayes' Rule and Dick Cheney's One Percent Doctrine
So, what about Cheney's "One Percent Doctrine" for justifying torture? Even worse! Let's suppose that there is a 1% chance that a detainee has information about a terror attack. Now suppose that torture is 90% effective in the sense that if that detainee is conspiring with terrorists he "confesses" and gives information about it with probability 0.9, but also confesses (with whatever made-up details he can think of) with probability 0.1 if he is innocent. (This, I think, is being generous to the effectiveness of torture!) Then, GIVEN a confession, the probability that there was really a plot is just 0.009/(0.009+0.099) = 0.083 - less than 10%!
The conclusion here is that the one percent doctrine logically fails when there is even a small chance of getting false positives from your intelligence-gathering resources and methods. It seems from what you hear that torture leads to sufficiently many false positives that it probably isn't helping, and is probably HURTING our security by leading our enforcement agencies on wild goose chases! Food for thought!

Cap and Trade Basics
1. Think of the benefits to the private sector from pollution. ... it’s cheaper ... to produce goods if you don’t worry about whatever emissions result as a byproduct.
2. A cap-and-trade system puts a limit on overall emissions, so that emitters have to pay a price for emitting.
3. The cost to the economy of this limit is the benefit the private sector would have gotten by emitting more than is allowed under the cap.
4. The creation of cap and trade means that emission permits command a market price, and the value of these permits ... (a growing fraction over time) would be captured by the government through auctions, and ... in effect, recycled to consumers.
A couple of notes for those who don't want to read the original: 1. the costs in (3) are not very big - they are a deadweight loss triangle, not the total market value of the permits (which is what some guesstimates of the costs say); 2. the current and future environmental benefits of the cap may or may not outweigh the losses to firms; 3. assuming that the "cap" does a good job of balancing firms' losses with environmental gains, an auction is more efficient than a Pigouvian carbon tax which is more efficient than the current system of "cap and regulate," which is in turn more efficient than subsidizing emission-reducing investments (*see below); and 3. the effectiveness or fairness of how the government is able or willing to "recycle to consumers" the revenues generated is something we can have a fair debate about.
* Note on policy options: Cap and trade and a carbon tax both have the advantage of allowing the firms for whom it is most expensive to cut emissions to emit more if they are willing to pay, whereas those for whom it is least expensive have an incentive to make more cuts. Firm-by-firm regulations do not achieve this, and subsidies have the unintended long run side-effect of leading to higher consumption of the very things whose production results in emissions. In theory, an auction does a better job of "getting the price right" for a given desired quantity. One thing that might tilt in favor of a tax over an auction would be setup costs - designing an auction that gets the price right is a difficult problem in theory and in practice.

Using Derivatives for Good Instead of Evil
The Danish model has another critical and innovative feature. Holders can retire their own mortgages by purchasing the same face amount of mortgage bonds at the prevailing market price. To prepay a mortgage by purchasing bonds, the home owner must give advance notice of several weeks to the MCI [mortgage credit institutions], which designates by lottery the specific bonds to be purchased. Thus, if rising interest rates or other factors cause mortgage bonds to trade at a discount, home owners can reduce the principal or retire the whole mortgage by purchasing an appropriate mortgage bond at a discount.This is an example of innovation that would make markets more robust help prevent foreclosures, rather than the types of innovations we've seen in the US, which are mostly meant to subvert regulations. The fact that this has not evolved in the US makes me think two things: One, that the balance of power IS tilted in favor of banks and against the consumer (maybe due to lobbying power, which Adam Smith and other "classical" market economists warned against); and two, that the regulatory framework has created some degree of moral hazard and/or regulatory capture (i.e. banks are taking risks and doing things way beyond what they would normally do because they do not face consequences from the market, i.e. bailouts, or the regulators, i.e. bureaucratic corruption) over the last 30 years.

Incentive to Die?
Australia (which had been facing unusually low population growth) that
awarded new parents a couple thousand bucks to have a kid during a
specified period (let's say ending June 30 because I can't remember the
exact dates). Well, the story went, there were an unusually large
number of births on during the last week of June that year, and
especially on June 30 (along with a correspondingly low number during
the first few days of July). There were lots of theories about this,
including: (1) fraud, getting doctors to put June 30 for a baby born on
July 1; and (2) inducements and/or cesarian sections scheduled before
the deadline.
Bush (W, not HW) put through a law that would
decrease and eliminate the estate tax by 2010, but with a rebound to
pre-Bush levels in 2011. How did no one accuse Bush of creating a death
panel?!? Wouldn't this promote some combination of fraud or worse,
euthanasia? Part of me says, "Let's leave it that way and see what
happens - it would be a neat experiment on the limits of tax
evasiveness," but that wouldn't be ethical. Instead, something needs to
be done to either make sure it is slowly phased back in, or not
reintroduced depending on your political fancy.
Sleep in the Age of Rational Expectations
Lately I've developed a new theory as to when I sleep especially well (in general I sleep well so the variance is not so large). I believe that I sleep especially well when I end up going to bed at exactly the same time I expect to be going to bed. On the unusual occasions when I don't sleep well, it is because I have been winding down my body and mind before I actually have the opportunity to fall asleep. Somehow when the later chance to sleep comes, it is too late for that sleep to be deep. Or so it seems to my mental econometrics; it would be interesting to measure it.
Interesting, yes. Testable? Hmmm.

3. ...The IBD/TIPP polling operation has literally no idea what they're doing. ... For example, I don't trust IBD/TIPP to have ... selected ... a random panel, which is harder to do than you'd think.

A Brander & Spencer Style Strategic Trade Prisoner's Dilemma
Elsewhere, the story points out that not a single manufacturer of any
significant size has gone under during the recession. There is a serious problem
here. No government wants its national champion (or champions) to be the one
that goes under, and so governments provide such support as is needed to pull
companies through tough periods.
Oligopoly, subsidies and trade. I question, however whether subsidies are the best strategic policy. If the nature of competition is Bertrand-style price competition, then export subsidies can improve domestic welfare (assuming no retaliation - heroic!). If the nature of competition is Cournot-style quantity competition, then tariffs and/or export taxes are appropriate in the absence of retaliation. Export taxes have the same proportional impact on relative prices as import tariffs; subsidies do the opposite, and worsen the terms of trade (price ratio of exports to imports) of the country offering them.

Does this Recession Make the World Look Fat?
The answer to me is twofold: (1) 1990s globalization centered on growth in components; and (2) trade is not a value-added concept like output is. For the first, the basic idea is that instead of countries specializing and producing all of certain finished goods that are consumed by end users, the recent explosion in trade was in components - countries specialized in a particular part of the finished good. Since trade is not a value-added concept, so within this integrated supply chain, you can have the value-added of a 20,000 dollar auto counted many times - the steel ($5,000) gets shipped from China to 3 other countries where components are made (at, say, $2,000 of value added in GDP per country), then to Mexico for assembly (another $4,000), then managerial, transportation marketing services by the US (for about another $3,000), and sold in Canada for $20,000 (the retailer's value-added is $1,000). If this car disappears from world trade, it amounts to a reduction of world GDP of exactly $20,000 because GDP only counts value-added. However, trade (imports plus exports is a common measure) is reduced by $(5,000 + 11,000 + 15,000 + 19,000)x2 = $80,000 due to the multiple counting of the total value at each stage of shipping instead of only counting each country's value-added.
So, the world is not getting fat (it's approximately as flat as it was last year) and I'm neither shocked nor alarmed at the decline in trade (at least, no more shocked or alarmed than I am about the decline in output generally).

Do Deficits Matter
To the extent that the source of the rise in a deficit is increased government
spending, then whether that rise is justified depends on how socially valuable
are these government expenditures. By that I mean the social rates of return on
these expenditures, such as longer lives for the elderly, relative to the
interest cost of raising the required funds, and relative to the returns on
other investments in the economy.
So, on this principle, if you have a trillion dollars to spend, would you spend it on 5 years of war in Iraq or 10 years of universal health care?

Overbetting Longshots
we find evidence in favor of the view that misperceptions of probability drive the favorite-longshot bias, as suggested by Prospect TheoryI.e. it's not a love of risk in the utility functions of gamblers, it's statistical illiteracy. They can't figure out that a 29:1 longshot has at best a 1/30 probability of winning (if the odds are "fair").
One problem I have is that, to Gelman and others this research contradicts theories of rational choice. Not so. It suggests that people are either (a) poorly informed; or (b) process information poorly. To quote a Larry Summers finance paper, “THERE ARE IDIOTS. Look around.”

Stumbling Blocks or Building Blocks
Countries may worry that a multilateral deal would erode the preferential terms they got through bilateral ones. If so, the flurry of bilateral deals may have come at the expense of a world trade agreement. Gary Hufbauer of the Peterson Institute of International Economics in Washington, DC, thinks that China and India have decided they would “rather pursue bilateral FTAs than make the necessary concessions to push Doha across the finish line.”This is more disturbing than any specific national protectionist policies because it undermines the WTO, the MFN principle, and multilateralism.

Our Portfolio of Imperfect Institutions
First, a large share of our economic output is now produced by large companies whose sales exceed the gross domestic product of many countries of the world. The vertically integrated supply chains of these large, often bureaucratic institutions seldom involve markets....
Second, market output represents a subset of total economic output. ...time and energy to caring for ourselves, our families and our friends ... activities that improve our own living standards ... men now devote more time to housework and child care than they once did. As we move toward more equitable sharing of unpaid work, policies designed to help wage earners meet their family responsibilities ... seem expensive to us in part because we have taken women’s unpaid work for granted in the past.
Third, the present and future costs of environmental degradation are on the rise.
Markets aren’t the only imperfect institutions in our world. Governments, families and Mother Nature are also susceptible to failure.
The point is, like it or not, we rely on a portfolio of imperfect institutions — a mixed economy.

Damn Imported Bald Eagles
More on the similarities between Presidents Obama and...
Yup, I've covered it before: Nixon was a self-proclaimed Keynesian; Nixon proposed a "negative tax" that would effectively reform welfare and still help the poor. Now, I've seen it all. Nixon favored a national health program that offered universal coverage. Here's proof. The principles of it:
First, it offers every American an opportunity to obtain a balanced,
comprehensive range of health insurance benefits;
Second, it will cost no American more than he can afford to pay;
Third, it builds on the strength and diversity of our existing public and
private systems of health financing and harmonizes them into an overall system;
Fourth, it uses public funds only where needed and requires no new Federal
taxes;
Fifth, it would maintain freedom of choice by patients and ensure that
doctors work for their patient, not for the Federal Government.
Sixth, it encourages more effective use of our health care resources;
And finally, it is organized so that all parties would have a direct stake
in making the system work--consumer, provider, insurer, State governments and
the Federal Government.

Economic History and the Variety Gains from Trade
The thing to highlight here is the importance of TRADE. Without expanding trade, it is doubtful that tea, coffee, and sugar could have ever become available. Hence, variety gains from trade. It only took until 1980 for Krugman to formalize it in the trade literature.Tea reached Europe from China in 1606, spreading to France in 1630, and finally to England in 1650...Coffee spread through the Middle East and arrived in Europe in 1615. Sugar, available before 1500 in limited quantities, only became affordable once production centres developed in the Caribbean starting in the mid 17th century.
By the end of the period, sugar, coffee, and tea constituted 7.2% of an average English household’s budget, and roughly 10% of their food expenditure...To put this in perspective, personal consumption expenditure on personal computers in the US in 2004 was only 0.6% of consumption expenditure, meaning that, by at least one metric, the average Englishman valued sugar more than the average American values his or her computer...
Prior to 1700, the average European consumed 182 kg of bread and 182 litres of beer per year...Half of all spending was on beer and bread, and fully three-quarters of all calories came from these two sources alone. The reason for massive beer consumption was simple – water was often contaminated. This was especially true in the cities. Brewed beer was safe. It is hence not surprising that it was consumed throughout the day, often with breakfast, and in all forms – including as beer soup in the morning...
Minivans, satellite TV, the internet, and mobile phones have made life better. The single biggest addition to welfare comes from the introduction of personal computers, credited by Greenwood and Kopecky with a gain of 3.5-4% of consumption expenditure. Compared to these figures, the gains for coffee, tea, and sugar look very large.

The usefulness of Venn Diagrams
lose to (who teaches junior high math) mocked the usefulness of Venn
Diagrams. Of course, they're pretty useful to illustrate logical
relationships, and according to Nate Silver at 538, Mr. Huckabee could have used them this past spring.
Conspiracies and Economic Statistics
In my view, the reason why so many hold onto these views is because it's so much easier to remain ignorant, and leap to the conspiracy view, than to do the hard work to understand why the statistics are imprecise measures of economic concepts, and why they are revised over time. After all, the former requires nothing more than taking somebody's word, the latter entails reading the supporting documentation, comprehending what the terms used mean, and applying some basic math and statistics skills...In other words the reason conspiracy theories attract a nice crowd of supporters is because people are "rationally ignorant." Being informed takes a lot of effort, and it's easy to believe a plausible lie (along with a dose of paranoia that the other side is lying) than it is to be bothered with the facts.
