Glenn Hubbard on the global savings glut

To what extent is weak financial intermediation in Asia part of the problem?

The Japanese case illustrates a general point absent from a discussion of a savings glut. The Keynesian reasoning assumes a simple black box between desired saving and investment–the financial system at home and abroad costlessly transforms lenders’ funds between savers and borrowers. A weak financial system–reflecting an underperforming banking system, poor investor protection and corporate governance, or fragile securities markets–yields a high cost of financial intermediation. For any given return on an investment project, savers’ net return is lowered by the high costs of intermediating funds. More broadly, regulatory restrictions in goods markets and labor markets reduce returns on domestic investment.

In a closed economy, high costs of financial intermediation increase the relative attractiveness of liquid, safe government obligations. (Again, household purchases of JGBs in Japan come to mind.) In an open economy, the international capital market offers the possibility of investing domestically generated savings in countries with a low cost of financial intermediation and/or a safe nominal anchor in government bonds–the U.S., for example.

Here is the full argument.

Subsidy Suckers

Depressing article from the Washington Post on the rise of lobbyists.
Lobbying

The number of registered lobbyists in Washington has more than doubled
since 2000 to more than 34,750 while the amount that lobbyists charge
their new clients has increased by as much as 100 percent…The lobbying boom has been caused by three factors, experts say: rapid
growth in government, Republican control of both the White House and
Congress, and wide acceptance among corporations that they need to hire
professional lobbyists to secure their share of federal benefits…

Lobbying firms can’t hire people fast enough. Starting salaries have
risen to about $300,000 a year for the best-connected aides eager to
"move downtown" from Capitol Hill or the Bush administration. Once
considered a distasteful post-government vocation, big-bucks lobbying
is luring nearly half of all lawmakers who return to the private sector
when they leave Congress, according to a forthcoming study by Public
Citizen’s Congress Watch.

No doubt this will create more calls for reform but the truth is we will never get the money out of politics until we get the politics out of money.

Is CAFTA a good idea?

Here is one lengthy criticism of the treaty.  Look there for the details, but here are my views:

1. The Bush Administration has not negotiated the treay on a bipartisan basis.  In part this is Bush’s core style, in part the Democrats have not offered much useful assistance.  If the treaty passes, the "pork cost" to swing Republicans will be high.

2. The worst parts of the treaty limit anti-AIDS drugs by extending intellectual property rights to Central America too strictly.  Yes drug companies will try to price discriminate, but the Brazilian solution may be better.  What will happen to generic medicines in Costa Rica?  Of course patent-breaking is a bad international precedent, but is Central America the relevant international tipping point for the destruction of intellectual property rights?  The net effect is difficult to estimate, read more here.

3. On the other hand, sooner or later these stronger patent protections might be imposed anyway, as Central American nations develop and join the global mainstream.  The question is how many people will die in the meantime.

4. More generally, the U.S. is setting bad precedent by using free trade treaties as leverage to negotiate other non-trade deals.

5. The treaty remains hostage to the interests of Big Sugar, as the sugar quota is barely weakened.  Nonetheless the sugar lobby still opposes the treaty, fearing a slippery slope of further erosion of privilege.  This is a good sign for the treaty.

6. Don’t worry that the agreement does little for labor rights or environmental protection in Central America.  Imposing such policies, before the recipient countries are wealthy enough to support them, is usually counterproductive.

7. The net move toward free trade is relatively small.

8. The biggest benefit of the treaty may be symbolic, by encouraging the Central American nations to embrace democracy more strongly and also to develop closer trade relations with each other.

9. Failure of the treaty would be a disaster, again for symbolic reasons.  Trade negotiations would slow down significantly, and the age of trade agreements might be over.

The bottom line: This is probably a treaty we should pass, but it is not a treaty we should be proud of.

By the way, Heritage is now running a CAFTA blog.  Russ Roberts has a more positive take on the treaty.  Matt Yglesias says thumbs down.

New book — The Market for Aid

…measures of aid quantity and aid quality seem to be correlated…The United States and Japan not only have the lowest effort among major donors, they also do relatively little targeting of aid to poor countries and to those with good policies…

That is Michael Klein and Tim Harford, two of the smartest people in the International Finance Corporation.  Are you interested in putting aside the polemics, and learning how foreign aid really works, or sometimes doesn’t?  Order the book here.

Do we have too much choice?

Ralphs shoppers aren’t overwhelmed by 724 kinds of produce because they don’t experience every variety as a separate choice. The exotic fruits are grouped together, as are the potatoes and yams, the lettuce bags, and the apples. Godiva sells its chocolates in selections–nuts and caramels in one box, dark chocolates in another, truffles in another–not piece by piece. Businesses have strong incentives not just to offer options but to help customers navigate those choices.

Outside the artificial constraints of a psychology experiment, people adapt pretty effectively to proliferating choices. We go back to our favorite restaurant and order the same dish because we know we’ll like it. We find a toothpaste that suits us and stick to it. We don’t always choose anew.

That is from Virginia Postrel, read more here.  Michael at 2Blowhards.com has more.

Will customers trust businesses to select for them?  If too much choice alienates you, won’t the store put the high-margin items on the front table right before your eyes?  Maybe so, but competition across firms should limit such mark-ups.  And if the mark-up gets too high, people will cope.  Schwarz himself notes: “A small-town resident who visits Manhattan is overwhelmed by all that is going on. A New Yorker, thoroughly adapted to the city’s hyperstimulation, is oblivious to it.”

The bottom line: I’m still upset that Rainier cherries — finer than caviar to my depraved, barbecue- and curry-obsessed palate — are available for only a few months a year.  Comments are open.

Bubble Schmubble

Is there a housing bubble?  Some say yes, some say no.  I say who cares?  The real question is not whether there is a bubble the question is, What are the chances that housing prices will fall dramatically?  Contrary to popular belief, knowledge of whether prices are following fundamentals or a bubble tells us very little about this question. 

An efficient market is not necessarily a stable market.  Indeed, an efficient market can be as or even more volatile than a market plagued by bubbles.

Consider the stock market – the price to earnings ratio can be written (using the Gordon Growth Model) as P/E=D/E*(1+g)/(r-g) where g is the growth rate of dividends and r is the discount rate.  Since r and g are small a small change in g can have a large effect on the P/E ratio – so much in fact that it is very difficult to reject a model of stock prices based solely on fundamentals (see my paper with Gary Santoni or the Barsky and DeLong classic Why Does the Stock Market Fluctuate (JSTOR).)

The principles are similar with respect to the housing market.  Do note that only a small fraction of the housing stock is available for sale at any one point in time.  When we hear about the high price of housing prices we think that the stock of housing must have gone up a lot in value.  But in fact all that has occured for certain is that the price for the marginal house has increased.  When the supply is inelastic (as it is on the coasts) and demand is fairly inelastic (as it is for most people who like to live where they work) small changes in either demand or supply can change the marginal price dramatically.  Thus, even if house prices are at fundamental values today and will be at fundamental values tomorrow a small change in say interest rates or the economy could make tomorrow’s price considerably lower than today’s. 

Why health care is good for you

Here are the bald asseverations I made to Bryan Caplan yesterday, over Bolivian food:

1. Health care is very, very good for you.  Here is one good summary of the earlier blogosphere debate.

2. Don’t be fooled by studies that say the opposite.

3. At most those studies show that health care is not good for you at some additional margin.  Make sure you get to that margin.

4. It is true that many regressions show a zero positive effect for health care once you introduce a variable for income.  This mainly shows that income is a better proxy for real health care than many of our highly imperfect measures for health care.

5. Almost every family in my Mexican village has lost a kid or two before the kid reaches age five.  Few of these deaths would have occurred if a) a doctor rather than a shaman were around, b) they had a ready antidote for scorpion bites, c) they knew to take the right pills for diarrhea and fever and to stay hydrated.  These variables will be more closely correlated with measured income than with whatever screwy figure the Mexican government provides for expenditures on medical care.  Health care still matters, even though it won’t show up as significant in the regression.

6. The above example can be generalized to wealthier countries.  Might education be the best proxy of all for the consumption of real health care?  Yes stupid doctors can kill you but a smart patient will not do better staying at home.

7. It is obvious that health care leads to greater longevity, and this is the greatest good of all.  Just ask yourself, how much money would you have to receive to give up health care for the rest of your life?  For me no sum of money would suffice.

8. Yes the famous Rand Corporation study showed that more doctor visits don’t help people.  I can buy that, but advances in medical science still bring huge pay-offs.

Caveats: These are lunchtime comments, I am not accountable for them in the same way as if I posted them on my blog.  And I am still too afraid to go see the doctor and get a check-up.

How much is politics in the genes?

In the study, three political scientists – Dr. John Hibbing of the University of Nebraska, Dr. John R. Alford of Rice University and Dr. Carolyn L. Funk of Virginia Commonwealth – combed survey data from two large continuing studies including more than 8,000 sets of twins.

From an extensive battery of surveys on personality traits, religious beliefs and other psychological factors, the researchers selected 28 questions most relevant to political behavior. The questions asked people "to please indicate whether or not you agree with each topic," or are uncertain on issues like property taxes, capitalism, unions and X-rated movies. Most of the twins had a mixture of conservative and progressive views. But over all, they leaned slightly one way or the other.

The researchers then compared dizygotic or fraternal twins, who, like any biological siblings, share 50 percent of their genes, with monozygotic, or identical, twins, who share 100 percent of their genes.

Calculating how often identical twins agree on an issue and subtracting the rate at which fraternal twins agree on the same item provides a rough measure of genes’ influence on that attitude. A shared family environment for twins reared together is assumed.

On school prayer, for example, the identical twins’ opinions correlated at a rate of 0.66, a measure of how often they agreed. The correlation rate for fraternal twins was 0.46. This translated into a 41 percent contribution from inheritance.

As found in previous studies, attitudes about issues like school prayer, property taxes and the draft were among the most influenced by inheritance, the researchers found. Others like modern art and divorce were less so. And in the twins’ overall score, derived from 28 questions, genes accounted for 53 percent of the differences.

But after correcting for the tendency of politically like-minded men and women to marry each other, the researchers also found that the twins’ self-identification as Republican or Democrat was far more dependent on environmental factors like upbringing and life experience than was their social orientation, which the researchers call ideology. Inheritance accounted for 14 percent of the difference in party, the researchers found.

Here is the nasty clincher:

The researchers are not optimistic about the future of bipartisan cooperation or national unity. Because men and women tend to seek mates with a similar ideology, they say, the two gene pools are becoming, if anything, more concentrated, not less.

Here is the full story.

Theism vs Evolution II

Rather than answer all the objections put forward to my theism and evolution post let me state the argument in another way which should make it clear that I am (obviously) correct.

Suppose that God came down from the heavens tomorrow in all his glory, throwing thunderbolts, raising the dead, turning water into wine, whatever it takes to convince everyone of his existence.  If this were to occur I have no doubt that even Richard Dawkins, precisely because he is a rational scientist, would say ‘hmmm, perhaps I wasn’t quite right about all this evolution stuff.’  My point in the post is that many religious people don’t need the demonstration – they already believe and in so doing they logically question evolution just as Dawkins would if he came to believe as they do.

I always hated homework

LeTendre and Baker led a team of researchers who analyzed educational data collected in the fourth, eighth and 12th grades in more than 40 countries in 1994, as well as data from an identical study in 50 countries, conducted five years later.

Virtualy wherever they looked, the researchers found no correlation between the average amount of homework assigned in a country and academic achievement.  For example, teachers in many countries with the highest scoring students — such as Japan, the Czech Republic and Denmark — gave little homework.  At the other end of the spectrum, countries with very low average achievement scores — Thailand, Greece and Iran — have teachers who assign a great deal of homework, Baker noted.

Note that U.S. teachers have been increasing homework amounts, while Japanese teachers have been decreasing it.  In neither country do general achievement levels appear to be responding.

That is from Richard Morin’s WP Unconventional Wisdom column, although this installment is not yet on-line (I added the link to the text).  Here is a good summary, with more information, it notes that homework may place a special burden on poor families. 

We need to be careful about drawing strong inferences from negative results on heterogeneous data, nonetheless this fits my priors.  I worry about this more than grade inflation, although I suspect the latter, by making grades less informative, induces overinvestment in extracurricular activities.

Who is hurt by scalping?

Quiggin admits that resale possibilities will increase the overall demand for tickets and thus increase the overall revenue for charity.  But he sees a caveat:

Geldof is relying on donated services from musicians who would otherwise be selling them. To the extent that lottery tickets go to people who could not otherwise afford to pay, the musicians are giving up time, but not money (and getting good publicity). But with resale, the charity concert becomes a substitute for attendance at a standard concert. Musicians might reasonably change their minds about participation.

In other words, a charity concert — with tickets allocated by non-price mechanisms — might cannibalize the demand for other concerts less than would a market-clearing price event.  So the musicians can be better off with no ticket resale. 

But keep the following in mind.  Let’s say it is feasible to prevent or at least limit resale (otherwise there is nothing practical to argue about).  Any musician could limit resale for a selected non-charity concert, and allow resale for a charity concert.  The resold charity tickets would then be reaching a new group of buyers, rather than cannibalizing demand.  If you are not selling your tickets at market-clearing prices, why not allocate some of that surplus to the charitable event, rather than to scalpers for the non-charitable concert?

At the very least, Geldof is being hypocritical.  First, his rhetoric does seem to be simply anti-capitalist.  Second, he claimed that the ticket resale was being funded off the back of the world’s poor.  That is not true.  Most likely resale boosts charitable receipts, increases consumer welfare, and maybe lowers the future income of the participating musicians.  Those musicians are the backs in question, and no those people are not the world’s poor.
