The Amazing Keynesian Resurrection

I am dumbfounded at how talk of taxes and spending is focused almost exclusively on the demand-side stimulus effects rather than supply-side incentives.

This is certainly true for the question of maintaining the Bush tax cuts. Almost to a person, the question hinges on whether the "rich" will spend their tax cuts or save it. Funny how saving is seen as a negative! But even worse is the lack of serious argument on the effects of higher marginal rates at higher income levels on labor supply, entrepreneurial effort, and investment. I had to chuckle when one liberal outlet noted that while some of the highest income tax returns are due to small business income, those returns only represent a minor percentage of all small business. How is that relevant? And maybe we should actually be concerned with those small businesses that are actually profitable?

But the frosting on the Keynesian birthday cake came today with Bill Gross' (head of PIMCO, Pacific Investment Management) propoal for Fannie Mae and Freddie Mac to somehow reduce mortgage rates on millions of mortgages. The rationale? Here it is:

"That [action] would obviously benefit the homeowner to the extent of one-third of its future payments,” he said.

“In terms of real dollars, it’s a $50 billion to $60 billion push or stimulus going forward. In my estimation it would lift housing prices by 2 to 5 percent, which is an important policy objective of the administration.”

So let me get this straight. Since the Federal Government has tapped out the public's appetite for borrowing and spending, let's do it by subterfuge: take from bondholders and give to homeowners. Voila! Redistribution and Keynesian stimulus all at once.

Bondholders should be furious at such ideas. If homeowners want to refinance, let them do so on their own. And if they cannot, well, that is the deal that they entered into.

Information Economics and Medical Testing

I have been talking to some colleagues about the issues around medical tests, in particular whether some tests provide such low quality information as to be of negative value. The PSA test for prostate cancer is a case in point, especially for men of my age. Should men around the age of 50 get the PSA test? My understanding of this test is that it reports a number from 0 to infinity, with higher numbers and a positive rate of change being thought to signal the presence of prostate cancer. Critics of the test note a high rate of false positives.

There are many other situations where medical tests are possible, from full body scans to mammograms. None of these tests are perfect. They will fail to detect cancers (false negatives) and they will signal cancer when none is present (false positive).

There is definitely a community of health professionals who advise many patients to not get the tests – and this is not because the tests fail to provide value in excess of their cost, but because the tests are actually thought to be of negative value even without considering their direct cost.

Note that this idea conflicts quite extremely with an idea that many economists would hold, which is that any information is good. As one of my colleagues puts it: The test has been done, and your doctor has emailed it to you. Would you actually pay for an email filter that would prevent you from seeing that message? If the test has negative value, you would pay for a filter. If the test is of even small value, you would open that email!

This is an important question, of both personal and social value. It deserves adequate consideration. I am going to give some initial analysis, using a framework from Bayesian statistical and decision theory, which I think is the optimal approach.

I am going to begin with what I call a Robinson Crusoe world, where the decision maker acts individually and only in consideration of his situation. So third party effects, such as influence by doctors, will be ignored.

The information setup is as follows. Bear with me if you have not done Bayesian analysis for a while, but it is pretty straightforward. This is all standard stuff; if you want to read more I highly recommend an old survey by two of my UCLA professors: Hirshleifer, J & Riley, John G, 1979. "The Analytics of Uncertainty and Information-An Expository Survey," Journal of Economic Literature, American Economic Association, vol. 17(4), pages 1375-1421, December.

In a Bayesian decision setup, we have three kinds of variables: states of the world; messages, and actions. Here, we will have only two states of the world: cancer, or no cancer. Messages are what the test provides. Now the PSA test is a continuous variable, and later I will return to that characteristic. For now, think of the test as returning one of two messages, m1 or m2. Message m1 can be thought of as a low PSA, below a critical value, while message m2 can be thought of as a high PSA, above the critical value.

There are four possible (message, state) outcomes, illustrated by the two-by-two matrix at the top of this post: Two of these have the message being consistent with the state, (m1,s1) and (m2,s2). Then we have two outcomes where the message is in error: a false negative of (m1,s2) and a false positive of (m2,s1). Note in this I am assuming that m1 is the message that we will think of as being the “no cancer” message, i.e., a low PSA.

The key probabilities for decisionmaking will be the posterior probabilities, which are derived from priors and the joint message/state probability density. More precisely:

(1) Pr (s1|m1) = {Pr(m1|s1)Pr(s1)} / Pr (m1)

(2) Pr (s2|m1) = {Pr(m1|s2)Pr(s2)} / Pr (m1)

(3) Pr (s1|m2) = {Pr(m2|s1)Pr(s1)} / Pr (m2)

(4) Pr (s2|m2) = {Pr(m2|s2)Pr(s2)} / Pr (m2)

Note that the message likelihoods – Pr(m2|s2) for example – are a function of the test’s characteristics and quality. For better information quality, we want large differences in the probabilities of a message conditional on different states.

The last two posterior probabilities are the important ones as they are our posteriors after getting the bad message: the probability of not having cancer dependent on getting m2, and the probability of having cancer dependent on getting m2. Note that these two posterior probabilities will differ from their respective prior probabilities, depending on how far the ratios of Pr(m2|s1)/Pr(m2) and Pr(m2|s2)Pr(m2) are from 1. If Pr(m2|s2)/Pr(m2), for example, is much greater than 1, then the posterior probability of having cancer conditional on getting the bad message will be much higher than the decisionmaker’s prior probability. This means that m2 is a highly informative message.

Now we can consider taking actions conditional on a message. I will presume the action to be “treatment,” with the implicit understanding that that might just mean further testing. The decisionmaker wants to take actions that increase their utility, or well-being.

Suppose we take the action of treatment if we get the bad message, m2. Then we can write our expected utility conditional on m2 to be:

(5) E(utility|action,m2) = GAIN*Pr(s2|m2) + LOSS*Pr(s1|m2) - c

where GAIN is our health improvement from treating a real cancer, and LOSS is our health decrement from taking treatment when we do not have cancer (since we got a false positive test). Note that I do include the cost of the test, c, even though I am most interested in whether the before-cost, gross value, of the information can be negative.

Our expected utility conditional on message 1,

(6) E(utility|no action, m1) = -c

since all we do is pay the cost of the test when we get message m1. I could put an additional cost in here, if there were “angst” caused by the test, but I will pass on that idea for now.

The crux of the issue is illustrated by Equation (5), the expected utility conditional on message m2. The value of the test is going to be greater, the greater is the GAIN from treating a detected cancer and the greater is Pr(s2|m2). The value of the test is going to be lower, the greater is the LOSS from undergoing treatment when we do not have cancer, and the greater is Pr(s1|m2) – the probability of a false positive. (Note that false negatives do not enter our analysis directly, but they do indirectly since the probability of a false negative, Pr(m1|s2) equals 1-Pr(m2|s2), so the lower is the probability of a false negative, the higher is the probability of a correct positive.)

One might jump on the fact that the expected utility conditional on message m2 can be negative, even without considering the cost of the test. This is true, if the LOSS and/or the probability of a false positive are large.

However, we need to take a rational decisionmaking viewpoint. If the expected utility conditional on m2 is negative, then we should just never take the treatment! Granted, we will pay the cost of the test, but as I said at the beginning, some people seem to think that tests can be of negative value even without considering the direct cost of the test. From our point of view here, that cannot be true. Of zero value, that is possible, but not negative.

And there is yet another level to the analysis, which will show even more strongly the likelihood of a strictly positive value to any medical test that reports a continuous variable and that has the property that the test becomes more precise as we increase the cutoff. See this report from Johns Hopkins for some discussion, in particular the following:

"In general, a PSA value of 4 ng/mL is considered the cut-off for suspected cancer (although it may vary slightly by age), and levels above 10 ng/mL indicate very high risk. It is values between 4 and 10 ng/mL that are the most ambiguous; men in this range may benefit most from refinements in the PSA test. The risk of cancer based on PSA levels follows:

PSA levels under 4 ng/mL: "normal"
4 to 10 ng/mL: 20 to 30% risk
10 to 20 ng/mL: 50 to 75% risk
Above 20 ng/mL: 90%."

If the expected utility conditional on m2 is negative, then we should increase our cutoff to reduce the probability of false positives and increase the probability of a correct diagnosis (conditional on getting m2). For instance, if a PSA of 8 was our cutoff in the above analysis, then let’s use a cutoff of PSA=50.

In equation 5, increasing the cutoff will clearly increase our expected utility conditional on m2, for Pr(s2|m2) will increase and Pr(s1|m2) will decrease.

Now it is of course true that by increasing our cutoff, we are decreasing the chance of getting a bad message, that is, of getting m2. So we will be less likely to take action, but when we do, we can be pretty sure that we are doing the right thing.

With a low probability of m2, the overall value of the test may be negative, for we are always paying for the test and very rarely taking action. However, my point again is that the test must have value in the gross, before-cost, sense. Or to use the email analogy, if someone already emailed me the results of the test, I definitely do not want to delete that message before seeing it!

I could bring in considerations of angst of getting a test result that is not high enough to take action but enough to make one nervous, or issues of self-control -- an inability to commit oneself to not taking action (or not worrying) if the test result is not extremely high. But that will be for another discussion.

Can Someone Explain Why Net Neutrality Makes Sense?

Google and Verizon have made a proposal to deal with access over the internet.

The proposal says Internet providers should treat all providers of Internet content the same, and should not be able to block them or offer them a paid “fast lane.” It says the Federal Communications Commission should have the authority to stop or fine those who break the rules.

Eric Schmidt, head of Google, justifies their position with this:

Freedom from such discrimination is crucial for consumers and for fostering innovation among Internet entrepreneurs, said Eric E. Schmidt, Google’s chief executive, in a conference call with reporters. “The next two people in a garage really do need an open Internet,” he said.

Yes, and the next two guys in a garage also need free access to a supercomputer, lots of talented college graduates, and venture capital funding at TBill rates.

I suspect strongly that some consumers and some providers of content value the speed of access more highly than others. Economic efficiency calls for them to get that, so long as they pay the cost. Perhaps CEO Schmidt and others assume that their proposal will somehow result in everyone getting the technologically fastest access possible, regardless of cost? More likely, we will all get a mediocre level of service.

The US Postal Service has always given equal service at the same rates for urban and rural customers, even though the costs obviously differ. And Ma Bell (AT&T for youngsters) gave basic access to the phone system at the same prices.

I note that Ma Bell no longer exists in its same form, and the US Postal Service is about to die (only a slight exaggeration).

So I remain unconvinced. If I want to go faster than someone else, or let my customers go faster, why can't I buy a Corvette?

Sound familiar? Mark my words -- the next crisis.

President Obama today launched a call for more Americans to receive a college education:

"That's why I'm absolutely committed to making sure that here, in America, nobody is denied a college education, nobody is denied a chance to pursue their dreams, nobody is denied a chance to make the most in life just because they can't afford it," Obama said. "We are a better county than that, and we need to act like it."

Hmmm....So what were the critical elements of the subprime crisis? A push on the part of the US government to increase home ownership, especially among segments of the population that had traditionally not owned houses or held mortgages. A huge subsidy from the government to those who borrowed to buy a home (through FannieMae and Freddie Mac and through home mortgage interest tax deductibility). An industry of subprime mortgage brokers who, fed by large up-front fees paid for mortgage origination, found millions of willing borrowers -- even though the brokers often knew that the loans were not appropriate and had little chance of being repaid, unless home prices continued their seeming relentless climb.

What do we have with education and student loans? Well, certainly the push for more to attend college (do we remember the studies showing that home ownership leads to all kinds of social good?). We have a subsidy, in the form of student loans -- and with the recent changes in the student loan program (packaged as part of the health reform bill !!), those loans are made and owned by the US government. In the subprime mortgage industry, FannieMae and FreddieMac decided to dramatically increase their purchase and repackaging of subprime mortgages in response to the Federal government's wishes: if your boss wants more home ownership, you better not stand in the way. It is still unclear how the new Federally owned and managed student loan program will work out. In the old days, private banks made student loans. Now it will all go through the Feds, with the taxpayer on the hook through our general taxes. If the Federal government wants more Americans to attend college, how do you expect the political appointees in charge of student loan origination to behave?

Last, we have a growing industry of what I will call subprime educational institutions, or degree mills. These institutions, whether for profit or nonprofit, will benefit from enrolling students, helping them navigate the Federal student loan process, and collecting tuition. The increase in demand for degrees is palpable, and supply will increase to meet the demand. These degree mills will lack significant "skin in the game" just like subprime mortgage brokers -- they will enroll students who have little likelihood of benefitting from the program or even graduating. But tuition is collected up front, and then it will be up to the Feds to collect on the student loans. Even some of the better colleges and educational institutions will be tempted by the increase in demand, and new technology -- online education -- makes it even easier to provide the coursework (for subprime mortgages, the technological innovation was in software to process mortgage applications).

Hell, we even have the equivalent of the credit rating agencies -- let's call them Educational Testing Service and ACT, Inc. What -- there are only two main educational testing services? That is even less than the three main credit rating agencies!

Oh, and the new student loan reform also gives subsidies to those student borrowers who take work in public service, and it caps payments at 10% of income.

All of this reform is promised to save us, the US taxpayers, lots of money.

Multiple Choice: An Airline Pricing Question

It appears as a stylized fact that airlines are getting an increased portion of their revenue through pricing channels other than the "basic ticket." Examples: baggage fees; ticket change fees; food and drink charges; charges for pillows and blankets; optional and priced plans for early check-in; charges for extra leg room. Kevin O'Leary of discount carrier RyanAir has repeatedly suggested charging for the loo, but I don't think that has been implemented yet.

Why the increased reliance on these new revenue channels?

a) Behavioral economics: Consumers don't notice such charges as readily as ticket prices. (I try this with my cat -- hide the pill in her food, but she outsmarts me every time. But don't let me influence your choice; cats might be smarter than people. One of my favorite econ profs used to famously tell his graduate students: You all think you are smarter than dogs, but you aren't -- you're just quicker.)

b) All these things have positive marginal costs, so the airlines are simply learning to price services in line with their costs.

c) Price discrimination. People who travel with lots of bags, for e.g., are more likely to have an inelastic demand for travel, so use baggage charges as a price discrimination scheme. This is similar to IBM in the old days charging their mainframe computer users by the number of "cards" that they consumed. (For youngsters, in the old days, data and even programs were coded onto paper cards and fed into computers. Yes, it was a pain in the butt.)

d) That perennial issue of taxes, and avoidance thereof. According to an IRS ruling in January, the kinds of fees being discussed are not subject to the 7.5% airline transportation tax. See here for details on the ruling, including the IRS private letter.

e) Because they can.

And the answer is.....

On the Proper Role of Government

As reported in CNET:

On Thursday, Sen. Charles Schumer (D-N.Y.), posted an open letter to Apple CEO Steve Jobs, expressing "concern" over the iPhone 4's reported reception problems.

Need we say anything more?

Goldman Coughs Up

So Goldman Sachs wil pay the largest penalty ever assessed on a Wall Street investment bank, $550 million. By settling with the SEC, Goldman avoids going to court with the government. I imagine however that there will now be a slew of private suits, even though investors will get $250 million and the US Treasury the rest. Goldman states in the settlement document,

"It was a mistake for the Goldman marketing materials to state that the reference portfolio was 'selected by' ACA Management LLC without disclosing the role of Paulson & Co. Inc. in the portfolio selection process and that Paulson's economic interests were adverse to CDO investors. Goldman regrets that the marketing materials did not contain that disclosure."

This is exactly what I have said all along. Their marketing materials were clearly deceptive. Nobody with good conscience should have prepared those.

Now GS has to follow through with some employee discipline.

Subsidize the Media?

Lee Bollinger, ex-Provost of Dartmouth College and current President of Columbia University, wrote in an editorial in the Wall Street Journal that we should consider public funding of the press.

You cannot be serious.

Sure, I can see the arguments -- we fund research in academia, and that is unbiased. Plus we fund NPR and hey, the British have the rock solid BBC. As an economist, can't I see all the positive externalities coming from the New York Times?

Bollinger states that in regard to public funding of academic research,

...there have been strikingly few instances of government abuse. Indeed, the most problematic funding issues in academic research come from alliances with the corporate sector.

Well, I wonder what evidence he has to support this claim. In my view, government funding of research is great at pushing forward the mainstream, generally accepted vision. Climate science is a great example.

Bollinger's argument shows why you cannot use the standard kind of economic efficiency arguments on everything. If we agree to subsidize everything that gives positive externalities at the margin, where will we stop? There are way too many activities that generate benefits that cannot be appropriated through market transactions. A free market is not going to be perfect in that regard. But holding it to the standard of optimality is not right. We have to compare it to the real alternative, which would be public funding of some activities. Can you imagine what it would look like if we were to start funding the media. (Hint: What would happen to Fox? Or Drudge?)

PS. There once was a time when I used to listen to the BBC on a shortwave radio, they were so good. That time is long past.

iPhone on June 24th

The prices he gave were $199 for a 16gb model, $299 for 32 GB. Decent.

Looks like its new phone time. The FaceTime program is really neat.

And here is a picture that Jobs showed, I took it from macrumorslive.com, where I was following Jobs' address. Note that Tuck's Bridge program is all about the intersection of business and the liberal arts. Maybe Steve needs a third dimension: business, technology, and the liberal arts. Nice.

Video Calling -- How Cool is That?

I'm watching a live blog of Steve Jobs' address to the WWDC in San Francisco.

He saved one of the coolest features of the new iPhone for last -- video calling.

Are we in the 21st century or what?

An Insurance Story

I busted one of the panes in the rear window of my Toyota Tacoma yesterday. I was putting a piece of cedar decking into it, and just nicked the edge of the window -- shattered it.

Called a window replacement service and almost had a heart attack: $1200 for the Toyota OEM replacement window. $1200 for one stupid Finlander moment?

But...I could get a third-party replacement, installed, for $295. A call to a second service confirmed the OEM price but got the third party window down to $220.

Now isn't that amazing. The OEM window costs 5.5 times as much, and we are not talking small change here. There might be some, hopefully minor, quality difference -- on the fit, most likely. I will find out tomorrow when I see the window.

Why the huge price difference? Two things. One, a monopoly position in the OEM window, due to the brand of Toyota. Second, insurance. Most people with comprehensive insurance will just pay the deductible and will therefore go for the more expensive but brand name window. Me, I cannot justify sending that kind of money to Toyota no matter who is paying, so even though I have comprehensive, if that third party window is OK it is going in.

What a lesson in what insurance can do to demand and prices! Do we wonder why medical services cost so much?

One of my colleagues had a very interesting proposal for health insurance that I have not come across. There are proposals to pay health care providers a lump sum -- bundled payment -- for a patient with some diagnosis. Say you need a hip replacement; then your insurer would pay the provider a lump sum of like $12,000. My colleague takes this one step further: he would have the insurer pay the patient the $12,000 and let them get their hip replaced wherever they wish.

That would create some very neat incentives! The problems, and they are important, are several. Foremost is the risk that the lump sum won't be enough to cover some complications. That puts additional risk onto the patient. Second might be the issue that some folks would rather take the money than the new hip. So we would have a nation of limping, but wealthier, elderly.

More on Carried Interest

I received the following comment on my initial post on carried interest:

One way of framing the carried interest question is to find the policy that preserves
the favored tax treatment in the aggregate. If I hold an index fund, my dividends
are taxed at a 15% rate and my realized long-term capital gains are taxed at a
20% rate. Now suppose I hire you to pick my stock for me. However we tax you,
there should be a consistency so that the aggregate dividends and capital gains
are still taxed in a favored manner.

My way of thinking of this would be the following: Suppose a set of friends get together to buy stock. There are five of them and they each put up 20% of the capital. They do well, and decide that one of them who has been bringing the best advice to the group should become the "general partner" and do most of the work. For that, the other four agree to reduce their share of any portfolio gains from 20% to 18%, so that the fifth partner will get 28%.

Since the aggregate capital gains are still the same, the argument above would imply that the manager/GP in my example should get capital gains taxation on his 28% just like the other four "limited partners."

This is a nice analogy, and analogies are nice for framing the issues and perhaps particularly for thinking about horizontal equity issues (are folks in this situation being treated similarly to folks elsewhere doing essentially the same thing?).

But this argument does not trump, for l return to the issue of economic efficiency -- what activities do we want to favor from an "activity level" point of view? By giving our newly minted General Partner the ability to get capital gains treatment on his larger share of the pie, we are enabling division of labor in investment activities. If we made the GP pay ordinary tax rates on any larger share he was given by his partners, we would reduce the incentives the partners would have to take advantage of comparative advantage and specialization.

Do we want to encourage such division of labor? Well, that is the question -- do we want to encourage the supply of specialized labor into management of private equity and venture capital? Perhaps. Capital gains rates are low after all because we want to encourage long term investments over short term.

The Carried Interest Dilemma

A couple colleagues and I were discussing the "carried interest" issue today. In a nutshell, a private equity firm, and other investment vehicles as well, such as venture capital firms, are organized as a partnership, with limited partners (LPs) providing the cash to invest and the general partner (GP) providing the management (and maybe a little bit of cash). The GP is often compensated in two parts, as memorialized in the phrase "2 plus 20": the GP gets 2% of the assets as a management fee, but they also get 20% of any gains when the investment is closed out.

The controversy is over Federal taxation. Now, the 2% is taxed as ordinary income (high rates!) and the 20% is taxed at capital gains rates (lower). Many folks feel that is unfair, letting these rapacious private equity fellows pay such low taxes on huge capital gains.

Before going too far into this, the right question of course is: what will be the different economic outcomes of different tax policies, and what do we think of those outcomes? Fairness is not foremost in my mind -- incentives, behavior, and outcomes loom larger.

It is not hard to think of analogies where similar compensation is paid. The taxation of those situations is instructive. For analogies, how about employees' grants of stock or stock options? Suppose I give stock to an employee, to create incentives for her to increase value. At the time of the stock grant, my understanding is that the value of the shares at that time is income, taxed at ordinary rates. Any capital gain in the stock would be taxed at capital gains rates, assuming the holding period was long enough. If I give the employee options, there is generally no tax due with the option grant, but when exercised, the difference between strike price and market value is ordinary income, unless the stock obtained through exercise is held for a certain period of time.

Another interesting case to consider would be if I lent money to an employee with the requirement that they use it to buy stock. My guess is that what would be taxable at ordinary rates here would be any difference in the interest rate charged the employee versus market rates. If there was a capital gain on the stock, then those would be taxed at capital gains rates.

This latter situation is close to what is happening with private equity. The GPs are being given an interest free loan to buy 20% of the portfolio. They should certainly pay taxes on that interest free loan.

A paper that comes to this conclusion is: Cunningham and Engler, The Carried Interest Controversy: Let's Not Get Carried Away, 61 Tax L. Rev. 121 (2007-2008).

But there is more than just the interest free loan, as the GPS essentially get to buy the shares at a zero price as well.

The more appropriate analogy seems to be the options one. The GPs are being given a call option on 20% of the portfolio, with a strike price of zero. Following the employee stock option tax policy, the grant of the option is not a taxable event. But when the option is exercised, it would be taxed at ordinary income rates, unless the GP somehow maintained their investment position for a period of time after that.

The idea of not taxing the granting of the option but taxing the gain at ordinary rates seems a nice balancing of our desire to stimulate incentives for creating long term value against the creation of excess incentives to enter one specific industry or profession. The tax advantage is essentially one of deferment of taxes -- no tax liability upon grant of the option, but upon exercise.

I think this solution balances nicely the incentives we want to preserve for investments that create value against giving excess incentives for supplying talent to certain industries.

Apple the Second Largest Company by Equity Value

Many stories have reported that Apple today overtook Microsoft in the market value of its equity.

What is more interesting is that Apple is the second-largest company in the US by market value of equity -- second to Exxon Mobil. See here.

Including debt to get total company, or enterprise value, would change the rankings as Apple has no debt and Microsoft has some. And of course other companies may have a lot more.

But it is still very impressive for a company that was almost dead a little over ten years ago.

I still remember the first Apple I bought...an LC 475. It had something like 4mb of ram -- I had to always play around, shutting off some of the built in system components, to get it to run certain programs. That was the first machine I bought for home use, and I have never bought anything other than an Apple since.

Nuke the BP oil leak?

I think BP is in big trouble, as is the Gulf of Mexico. It is a real tragedy for sure -- the only surprising thing so far is the seemingly small amount of actual damage to wetlands, beaches etc. Perhaps I am not paying enough attention, but the internet is not exactly overwhelmed with pictures and evidence of oil everywhere.

But the stories starting to come out on how BP folks made ill-fated decisions that possibly led to the disaster are scary for the company. Larry Kudlow on CNBC has been railing against BP for days on end...he just referred to them as an enemy of the US. Now that is because of something the company is supposedly doing in Iran, but Kudlow mixes Iran and the Gulf in a pretty vitriolic diatribe against the company.

Then there are these stories about how Russia used tactical nukes to stop blowouts back in the USSR days...supposedly did it five times and it worked four out of the five. Hmmmm...what about that fifth time?

Here is the Russian newspaper story that I guess discusses the use of nukes in blowouts. If you cannot read Russian, try this. Where is Red Adair when we need him?

Cyanobacteria in lakes vs. bacteria in pools

The local vigilantes on my beautiful New Hampshire lake have been spotting and reporting cyanobacteria blooms for two years now. Cyanobacteria are naturally occurring bacterial that do at times give off toxins that can cause harm to mammals. Dogs have been known to become sick, although I am unaware of any confirmed cases of human illness. Last summer I got very concerned when some local researchers reported -- in an unpublished paper that nonetheless got much local press-- a statistical correlation between living close to freshwater lakes and onset of ALS, or Lou Gehrig's disease. I don't know where that research now stands, but in my considered opinion it suffered from serious defects. One of these potential defects was the way cases of ALS were reported. I actually got an email from someone on my lake who said that anyone knowing of ALS cases around our lake should report them to the researchers. Hmmmmm....I wonder if a similar email went out to folks who don't live near a lake?

Anyway, the risk from cyanobacteria is incredibly small, especially if one doesn't swim directly in visible blooms (I like to cite a WHO report that said if you are standing in kneedeep water and cannot see your toes, you probably should not go swimming. Hell, even those of us from the UP would figure that one out!)

But finally, the CDC has come out with a report saying that 1 in 8 public swimming pools pose immediate infection risks.

I always told people who asked about cyanobacteria in my beautiful clean Goose Pond: maybe if you are worried you would prefer to go to the pool at Storrs Pond in Hanover and swim in chlorinated water that a bunch of little kid have....well you don't want to know.

Risks are everywhere.

Is Greece Facing a Liquidity Problem or it it Truly Insolvent?

I imagine that the Jean-Claude Trichet has dealt with more pleasant situations than the one over the weekend.

Last week, Mr. Trichet was broadly quoted as saying that the European Central Bank had not even considered the option of buying European government bonds.

Today, the ECB announced that it would indeed be buying government bonds, but that the Bank did not bow to any pressure in coming to this decision -- see here for a sample of one of the hundreds of stories.

OK, no political pressure but certainly a lot of bond market vigilante pressure!

The issue for the US back in 2008-09 was whether banks were insolvent or illiquid. The line there is a gray one to be sure. I support the lender of last resort stepping in during liquidity crises, which in modern banking systems are inevitable, but not to rescue truly insolvent institutions.

The question then is: is Greece insolvent or just illiquid?

This looks to me like massive monetization of European debt, which will not be good for the Euro. And, unlike the US, much if not most of Europe has very little leeway for additional taxation. The US can solve its debt problems, in the worst case scenario, by increasing taxes, most favorably through a VAT. I am certainly not advocating that we do this; I would prefer to see the pressure kept on to cut spending. But if need be, I think the US could raise several percentage points of GDP through a VAT with very little cost to the economy. I don't think that Greece, or many other European countries, could do that.

Seems to me that insolvency is the more likely situation, and bailing out insolvents cannot be good policy. The only offsetting arguments are that the state of the markets do raise liquidity issues for other countries, if Greece were to be let go.

Tough decision for the ECB.

Are Apple's Actions Anticompetitive? Doubtful

As has been widely discussed, it appears that Apple will be preventing iPhone applications developers from using anything other than Apple-approved development tools -- ruling out, among other tools, Adobe's Flash CS5. See here for more of the facts and here for more editorial comment.

Do these kind of restrictions rise to the level of being anticompetitive in the sense of antitrust? Let me sketch some possibilities, none of which I think make for a reasonable business strategy nor do they meet any kind of anticompetitive test. The most likely explanation is a very non-strategic one, simply that Apple wants to make sure that its iPhones and iPads meet the kind of quality test that its vertically integrated Mac platform does. Applications can impact the overall user experience in a variety of ways, and Apple has all the incentive in the world to make sure that they do not impair performance.

It pays to go back and re-study the Microsoft antitrust case. There, the government's claim was that Microsoft was excluding other internet browsers such as Netscape from the original equipment market, mostly by bundling its own browser (Internet Explorer) with its operating system, Windows. The alleged reason for this exclusion was Microsoft's desire to protect its market power in the operating system market. Interesting - the actions were not designed to gain market power in the browser market, but to protect a position in operating systems. Supposedly, Microsoft feared that as other browsers got traction, software developers could write applications that would interface directly with the browser (so called middle-ware) rather than having to interface with the operating system itself. Once applications could be written for browsers, Windows would potentially face more potential entry into the operating system market, since new operating systems would not face the chicken-and-egg problem of not having any applications that could interface with it. That is, the argument was that Windows had a nice network externality working for it, through software developers, and the middleware concept was seen as a threat to the market power that that network externality conveyed.

Now this is not the only possible angle to thinking about Apple and the exclusion of non-approved development tools, but it is an interesting one to consider. That is, could Apple be excluding some development tools to protect its position in a related market?

What market might Apple be trying to protect? Maybe its the Applications Store platform? This is what the post by John Gruber linked to above builds on. Can one build a coherent argument that Apple is restricting development tools so that the Apps Store becomes a standard, for purposes of exploiting market power? This is not unlike some of the earlier antitrust claims, more popular in Europe, that Apple put restrictions on iPods and iTunes so as to lock customers into both platforms.

I think there is one big weakness in any anticompetitive angle to this story, and that involves the inherent lack of power of a standard on an applications store platform. Recall the essential source of market power in the Microsoft story: the software development network externality, whereby the fixed costs of writing for different operating systems gave the operating system with the largest installed base an insurmountable advantage.

I cannot see anything working the same way in the mobile phone applications market. One possibility would be to get all developers writing for the iPhone platform, thereby giving the iPhone and iPad the chicken and egg externality benefit. But the mobile phone market is way too competitive for this story to hold water. The market share of iPhone is around 25%, with very strong competitors. Maybe for the iPad, but that is a whole new market that is too early to even assess for viability. I also do not know how much credence the "fixed cost of development" story should be given here. With Microsoft, I could see that writing something like a whole new spreadsheet package for a new operating system, and overcoming the advantage of installed base of existing products, would be a real challenge. But for mobile apps? Are the fixed development costs really going to prevent apps developers from writing more than one version of a product, if there were two platforms with different requirements? Isn't the gaming market a point against this argument, with popular games being written for the different platforms all the time?

Maybe the Apps Store market itself? Could Apple be trying to protect a dominant position in selling applications? Doubtful. For one, if that were the objective, I fail to see why restricting product would be beneficial -- does Amazon restrict products from its site? Second, it is way too easy for competing applications stores to launch and compete.

I am left with Occam's Razor, having to accept the simplest explanation: Apple wants to approach what it would have with a fully vertically integrated chain from hardware to operating system to applications. That means putting some restrictions on the applications.

There's an Ad for That!: Apple's Amazing Innovation Juggernaut

Apple was on a tear this week. Last Saturday, they had a very successful launch of the iPad, opening up a whole new category for exploration and innovation. Our lives, in short, just got even more interesting and better. Then later in the week, they gave a preview of the new iPhone operating system, which powers not just the iPhones but the iPad as well.

Among the new features was an ability for application developers to include advertisements that run inside of applications. This takes the amazing evolving world of mobile applications to a new revenue-generating level.

The opportunities are going to be pretty incredible. Advertisements will be able to use the GPS capability of the iPhone. So, if you are using an app that looks for restaurants, and you are standing in Marquette, Michigan, well then I would hope that Jean Kays Pasties on Presque Isle Avenue would drop you a nice little note inviting you in to try one of the Upper Peninsula's true delicacies.

Think of how this is a change from Google's search-based advertising. With Google, ads are focused on the search terms that you type in. With Apple, the ads are tailored based on the app you are running (and there are thousands of those) and then the infinitely variable physical location. Plus who knows what else?

The other thing that Apple did was to take another step in the standards war going on over HTML and Adobe's flash. Apple will restrict developers to using programming languages approved by Apple, and that is presumably not going to include Adobe's package that converts Flash based apps to run on the iPhone. I am not quite sure what is going on here, but certainly Apple's control of the entire vertically integrated package of software and hardware has been key to its success so far. I can see obvious potential for some third party programs and languages to impinge on the overall value of a device, from the consumer's perspective. Whether Flash presents those problems, or if something else is going on, that I cannot say.

Stupak to Retire

More fallout from the health care bill. This time, Representative Bart Stupak of Michigan has announced -- or will soon announce, I guess -- his retirement.

Stupak it turns out represents my home territory, the Upper Peninsula of Michigan. I thought I recognized a faint Yooper accent. I saw him on CNN yesterday while he was giving a speech in Bessemer, Michigan.

Well, well. Interesting times for sure. Stupak was the leader of the pro-life argument against the health care bill, and had been leading a bloc of pro-life Democrats against the bill. At the very end, he voted for the bill after getting the promise of an executive order from the President that promised to continue current Federal prohibition against financial support of abortions.

Folks will have different takes on what this means for, well, just about everything. The weekend papers will make for good reading.
