Moral Wiggle Room

If Bob and Alice prefer vanilla to chocolate ice cream then when given the choice we wouldn’t be surprised to see each of them choosing vanilla.  Now suppose that Bob and Alice are given the following choice, if either chooses vanilla they both get vanilla only if both choose chocolate do they receive chocolate.   If Bob and Alice prefer vanilla to chocolate it seems plausible that they will continue to choose vanilla.  But suppose that we observe Bob and Alice choosing chocolate in the second experiment.  How might we explain this?

Imagine that chocolate is considered sinful and vanilla is thought to be nice.  Bob and Alice might want to be sinful but they choose nice in the first experiment to avoid social condemnation.  In the second experiment, however, Bob and Alice are sinful only when both sin.  True preferences are revealed only when no individual can be singled out for condemnation.

That’s the setup of one of the clever experiments in an excellent new paper, Exploiting Moral Wiggle Room, except the experiment isn’t about chocolate and vanilla ice cream it’s about fairness in a division game.  In the first experiment Alice and Bob must each decide whether to choose $6 for themselves and $1 for a third party (Cindy) or $5 for themselves and $5 for Cindy.  In this experiment most Alice and Bobs choose to be nice, they divide "fairly" with Cindy.  Many researchers have concluded that Alice and Bob must have a preference for niceness.

But put Alice and Bob together in the second experiment and Alice and Bob are each much more likely to choose the sinful division, $6 and $1.  Alice and Bob may prefer chocolate after all.

Read the paper for several other experiments along these lines.  The implications for societal organization are profound.

Phone tax facts of the day

…the telephone tax is a very inefficient way to help poor people, says Thomas Hazlett, a professor at George Mason University, in a June white paper (senior.org/USFstudy).  One Hawaiian phone company is getting an annual subsidy of $13,345 per line.  It would be cheaper to give these people free satellite service.

Alaskans are getting rich off oil royalties but still qualify for an average $175 a year each in phone handouts.  The citizens of Jackson Hole, Wyo. are winners, too, to the tune of $282 each.  Does Harrison Ford really need your help?

That is from Bill Baldwin at Forbes.com.

What is the fuel cost of grapes from Chile?

Tim Harford writes to me:

Polluters in Europe currently have to pay about euros10 per tonne of carbon dioxide as part of Europe’s efforts to meet its obligations under the Kyoto agreement.  That is less than one penny per kg of carbon dioxide.  Perhaps that price, in a volatile market, is too low.  A Government Economic Service paper on the social cost of carbon emissions recommends a cost closer to euros25 a tonne of carbon dioxide.  Even that is less than 10p for a kilogram of mange-tout, or a penny for a 100g packet.  If consumers were forced to meet those costs – as in principle they should be – the sum would barely register.  There are good environmental reasons to tax airline fuel, but such taxes are not likely to make food imports substantially more expensive.

Here is the link, and Tim notes there are typos in the article, the text is correct as above.  When it comes to the social cost of food, one estimate is that congestion and accidents account for two-thirds of that sum.  So maybe you should walk or bike more, but eat what you want, from where you want.  Here is, again, my review of Michael Pollan’s The Omnivore’s Dilemma.

By the way, for a more skeptical view of a carbon tax, here is Robert Samuelson’s piece from today’s WP.

Addendum: The Economist (MMM?) refers me to a new "AntiPigou" and "Anti-Mankiw" blog, which I have yet to read.

How happy are French workers?

On the new (and anonymous) Economist blog, Maybe Megan McArdle writes:

A new working paper from the IMF
looks at the impact of the 35-hour working week in France, where it has
been imposed by law on large firms since 2000. The authors, Marcello
Estevao and Filipa Sa, find that the 35-hour week has:

(i) encouraged workers in large firms to take second jobs, or to move to small firms where the 35-hour week is not obligatory;

(ii) driven up hourly wage costs for large firms;

(iii) probably had "no significant impact" on aggregate employment;

and

(iv) brought no significant increase in worker satisfaction, as measured by the Eurobarometer opinion survey series.

I usually doubt the kind of questionnaire evidence that would go into the kind of judgment represented by iv), but nonetheless this is worth reporting.

The resurgence of the $2 bill

In 2005, depository institutions ordered $122 million in $2 notes,
according to Federal Reserve statistics.  That is more than double the
average amount ordered from 1991 to 2000.

…with banking and currency experts not certain what is fueling the
surge. A few possibilities are inflation, the introduction of the
Sacagawea $1 coin in 2000, and even, according to some, immigration.

Regardless
of the reason, anecdotal evidence shows that at the local level,
vendors and customers are getting more comfortable with $2 bills.

One
group that has embraced the note is the exotic-dancing industry.  Strip
clubs hand out $2 bills when they give customers their change, and the
bills end up in dancers’ garters and bartenders’ tip jars.

"The
entertainers love it because it doubles their tip money," said Angelina
Spencer, a former stripper and the current executive director of the
Association of Club Executives, an adult nightclub trade group.

In
addition to the inflation factor, Robert Hoge of the American
Numismatics Society thinks $2 bill demand may be getting help from
immigration flows, particularly from Canada and Europe, where currency
denominated in twos is common.

Peter Morici, professor at the Robert H. Smith School of Business at
the University of Maryland, thinks that with the introduction of the
Sacagawea, named for a famous Native American woman, people are
beginning to realize an inconvenience of $1 bills.  "In order to have a
successful $2 bill, you have to have a successful $1 coin," he said.

Here is the full story.  It is odd, is it not, that people would change their denominational holdings as the most efficient way around wage and price stickiness?

Purchasing Power Parity?

The value of a dollar in New York City is 76.2 cents.

Still a bargain, if you ask me, once you factor in live concerts at the Village Vanguard, which down here in Fairfax cost infinity.  (Of course Dickens you can read anywhere.)  Here is more, and thanks to Craig Newmark for the pointer.  By the way, I regularly enjoy New York magazine, the source of this article, even though I live all too far away.

America and Europe, continued

It is true that some European nations are at a par with the United States, and Norway (oil) and Luxembourg (financial services and small population) are above the United States.  But keep in mind that these figures for the top European performers are averages.  Creating low-wage jobs or taking in immigrants will lower such an average butthis effect should not downgrade the true economic performance of the United States. 

A further question is how much "cherry-picking" in Europe should be allowed (e.g., ruling out Greece), while not doing the same for within the United States.  Louisiana and Mississippi are a drag on U.S. averages, and DC probably looks like Luxembourg.

Note also that high rates of government employment, as we find in many parts of Europe, tend to overstate measured gdp.

If we look at recent rates of growth, whether of productivity or of gdp, the U.S. clearly is ahead of Europe, although a forthcoming U.S. slowdown may change that ranking at least for a while.  Much of this seems to stem from information technology, as best we can determine, not "American catch-up."  Try also the Lewis book on productivity.  The micro-evidence all suggests that the U.S. has obtained an ongoing flexibility lead in certain key categories, most of all retailing.

In short, if we view the numbers in context, they still indicate a serious economic problem for social democracy.  Try some demographic projections as well, and their implied economics, a topic on which Quiggin and CT commentators were conspicuously silent.

None of this is counting the America’s greater future capacity to either respond to globalization or absorb immigrants.  I’ve heard many a European envying the future of the American economy, but I’ve never heard of an American envying the future of the French or German economy (except perhaps at CT). 

As I said in my original essay, I still see two "plausible" scenarios for Europe not collapsing.  Eichengreen is yet more optimistic than I am.  But if defenders of social democracy continue to deny the problem, there is no reason to be optimistic at all.

Does downward nominal wage rigidity matter?

Michael Elsby says no.  In his view, if downward nominal wage stickiness is a potential problem, the relevant class of firms will simply start workers off at a lower nominal wage, raising it over time as need be.  The result will be "wage compression."

Elsby also claims that the Phillips curve trade-off between inflation and unemployment is not stronger at low levels of price inflation.  That suggests that nominal wage rigidity doesn’t much matter at the macro level.  If it did, proximity to that zero nominal cut point ought to boost the benefits of inflation, but it doesn’t seem to.

I am surprised by this argument, but I don’t (yet?) see reason to reject it.

The European Economy Since 1945

An excellent book appeared on my doorstep yesterday, by Barry Eichengreen:

Thus Europe, which had relied on extensive growth in the 1950s and 1960s, had no choice but to switch to intensive growth from the 1970s on.  The problem was that institutions tailored to the needs of extensive growth were less suited to the challenges of intensive growth.  Bank-based financial systems had been singularly effective at mobilizing resources for investment by existing enterprises using known technologies, but they were less conducive to growth in a period of heightened technological uncertainty. Now the role of finance was to take bets on competing technologies, something for which financial markets were better adapted.  The generous employment protections and heavy welfare-state charges that had given labor the security to accept the installation of mass-production technologies now became an obstacle to growth as new firms seeking to explore the viability of unfamiliar technologies became the agents of job creation and productivity improvement.  Systems of worker co-determination, in which union representatives occupied seats on big firms’ supervisory boards, had been ideal for helping labor to verify that owners were investing the profits resulting from its wage restraint but now discouraged bosses from taking the tough measures needed to restructure in preparation for the adoption of radical new technologies.  State holding companies that had been engines of investment and technical progress were no longer efficient mechanisms for allocating resources in this new era of heightened technological uncertainty.  They were increasingly captured by special interests and used to bail out loss-making firms and prop up declining industries.

I have never read a better paragraph on what the European economies have done right and subsequently did wrong.  Note that Eichengreen is, broadly, a social democrat.  Eichengreen (who is more optimistic about Europe than I am) believes that Europe can turn things around, without chucking the basic model, but he doesn’t for a moment deny that Europe faces an economic crisis relative to the American model. 

I am still shocked by the response of the CrookedTimber commentators to my short essay on social democracy over there.  It is not just a question of how one reads the productivity and growth numbers, but also there is a commonly accepted narrative of what is wrong with the major European economies.  Eichengreen is the one doing service to the social democratic cause.

The economics of remittances

Just how beneficial are remittances?  One loyal MR reader writes on his blog:

While undoubtedly a portion of remittances are sent back to the U.S. via purchasing power to buy U.S. goods and services, a portion is also kept in-country and used as an alternative monetary system or held by a foreign government as a source of "hard" currency to prop up its domestic money.

Money that leaves the U.S. and never comes back is great for the U.S. government.  Essentially it bought goods and services without ever having to pay up on it’s end of the IOU.  Therefore, shouldn’t Americans support remittances?  America doesn’t run out of money – we’ll just print more.

I am more interested in the effects on the receiving country.

Assume that dollars are sent rather than exchanged for pesos and that the remittance money never returns to the United States.  In essence we are inflating the parallel currency in Mexico (or Vietnam, or wherever).  This means more wealth for the people who receive the remittances.  But who loses? 

Some of the new money will just be inflationary.  People who compete with remittance receivers in consumer markets will face higher prices.

Output and employment will rise in regions with unemployed or underemployed resources, or simply in monopolized sectors.  If a Mexican uses the money to bribe a policeman, or hire a doctor, the quantity effect may outweigh the price effect.  This is the main source of net benefits to the receiving country.  But in perfectly competitive sectors this is just pure inflation.  Note that rural Mexico, where most of the remittances go, is far from perfect competition.

There is also an precautionary insurance gain from having more savings held in dollars, distinct from whatever is finally purchased with those dollars.

Of course, not all of the dollars will stay in Mexico.  Mexico, as a nation, gains to the extent those dollars buy goods and services from the United States, assuming of course U.S. markets are large enough that more Mexican buyers won’t push up prices for subsequent buying Mexicans.  So the best outcome, at least for Mexico, is if the remittances go to people who will carry them back across the border or spend them on imports.

If the dollars are exchanged into pesos, through Western Union, the story differs.  The rate for dollar-peso exchanges moves against the dollar.  This hurts people who have already accumulated dollar-denominated assets; usually those are previous receivers of remittances and of course American tourists who visit Mexico or who buy amates.  It also will hurt Mexican exporters.  Mexican importers gain accordingly.

In sum, it is a complicated story.  Yes, in many regards remittances are more like inflation — albeit in a parallel currency — than like real wealth transfers.  But there are also some important efficiency gains.

We also should not assume that distribution and efficiency are fully separate.  Perhaps the remittances go to people who know better how to invest the money.  Perhaps not.

Comments are open for analysis of remittances, but general talk of Mexican immigration will be deleted…

More new growth wisdom: Dani Rodrik and Jason Hwang

How does the introduction of new goods affect growth?  While recent
evidence has highlighted the role of new goods in raising the diversity
and sophistication of a country’s production structure, which in turn
matter for growth, little evidence tells us why.  I propose a simple
channel of impact relying on two building blocks.  One, there is a
convergence force operating at the product level.  The further behind
the frontier you are in a given product, the faster you raise quality.
Two, new goods are introduced with a greater distance to the frontier
than in existing goods.  I construct a Schumpeterian growth model with
these features to show how entry into new goods influences aggregate
outcomes by determining the range of products in which convergence
occurs.  Detailed trade statistics provide strong support for both
building blocks of the model.  Using unit values as a proxy for quality,
I find that unit values exhibit strong convergence – at about 5% a year
– for the great majority of products in the sample.  Also the gap in
unit values relative to the world frontier is larger for new goods.
Confirming a key prediction of the model, I further show that, holding
constant levels of development, unit values are inversely related to
measures of diversification and sophistication of a country’s exports.
This last finding helps to explain a recently documented puzzle
regarding the high sophistication and low unit values of Chinese
exports. (To be posted in early November)

Perhaps I will not be convinced (what goods can be produced reflects an unobserved heterogeneity in underlying conditions), but Hwang is worth watching.

Banishment

Today I am in Florida giving a seminar to a group of Federal judges on the law and economics of Federalism and Crime.  One of the surprising things that I discovered in my research is that cities, counties, and even most states can legally banish criminals from their borders.  I say most states because, for example, the Georgia state constitution makes banishment illegal.  Georgia judges, however, have found a way around the law they have imposed "158-county" banishment.  (If you guessed that Georgia has 159 counties give yourself two points.)

Banishment is a particulary noteworthy example of a negative spillover – banishment benefits the state doing the banishing but only at the expense of other states.  I will suggest to the Federal judges, therefore, that state banishment should be illegal.

There are some arguments for banishment from a city or county.  Banishment, for example, can remove a criminal from negative peer influences.  Whether the advantages outweigh the spillovers is an open question but city and county banishment should be left to the states because the state government can internalize the city/county spillover.

A simple theory of where the women are beautiful

For a few weeks twice a year, after Ramadan and before Christmas,
thousands of Lebanon’s young men return from jobs abroad – and run
smack into one of the world’s most aggressive cultures of female
display.  Young women of means have spent weeks primping and planning
how to sift through as many men as possible in the short time
available.  The austere month of Ramadan ended a week ago.

The
country’s high rate of unemployment pushes the young men to seek work
elsewhere, sometimes in Western countries like France and Canada, but
mainly in the United Arab Emirates, Saudi Arabia and the other oil states on the Persian Gulf.  The women, inhibited by family pressures, are generally left behind.

MR readers will not be shocked to learn these women strongly prefer the Lebanese men with foreign jobs and foreign incomes; here is the full story of competition and rent exhaustion.

My simple theory of where the women are attractive has two variables: income inequality, and the willingness of wealthier men to marry beautiful women from the lower income and social classes.  Women then compete for lucrative marriage prizes.  That puts Cuba (the wealthy men are the tourists) and Brazil near the top of the list, where they belong.  New York City isn’t bad, and this mechanism won’t hurt China either.
