*Selfish Reasons to Have More Kids*

The author is Bryan Caplan and the subtitle is Why Being a Great Parent is Less Work and More Fun Than You Think.  Both were true for me and I predict at least one will be true for you.  It is now available for pre-order on Amazon.  And here is Bryan, new to Twitter.

Median-itis and The Great Stagnation

Here is my NYT column from today, on themes relevant to The Great Stagnation.  I won't rehash this entire discussion, but I would like to focus on this one column excerpt:

From 1947 to 1973 — a period of just 26 years — inflation-adjusted median income in the United States more than doubled. But in the 31 years from 1973 to 2004, it rose only 22 percent. And, over the last decade, it actually declined.

I am noticing that some reviews or commentaries (and here) are citing per capita income growth as a response to my argument.  It is true that per capita income grows at a slower rate post-1973, but my argument is about the slowing down of median income growth and that is a much stronger shift.  The productivity data also tell a glum story.   

CPI bias can change those numbers in absolute terms (see comments from Russ Roberts), but it also changes the pre-1973 median income growth numbers and arguably more so.  The gap remains and TGS refers to the living standard for the average person or household in the United States, not the total amount of innovation, which remains quite high.  They're just not innovations with the same trickle-down or broad-based effects as in an earlier era.

Kindle eBooks are themselves a good example.  It's a real improvement for a lot of us -- especially travelers -- but even the median reader, much less the median American, doesn't have a Kindle or buy eBooks.  As I argued in The Age of the Infovore, the big gains of late have gone to the extreme information-processors.  

I've seen in the MR comments (and elsewhere) a lot of anecdotal comparison of recent gains vs. earlier gains in technology.  Don't we now have this, don't we now have that, and so on.  Of course.  Median incomes have risen somewhat.  But, when it comes to the average household, the published numbers for median income are adding up and trying to measure those gains and it turns out their recent rate of growth really has declined.  Most serious researchers who work in this area use and accept these numbers as the best available (though they do not in general advocate my causal interpretation; see for instance Mark Thoma or Jacob Hacker).  

If the numbers for median income growth are low we ought to take that seriously, as does Scott Sumner.  We are not cheerleaders per se (BC: "I'm baffled why Tyler would focus on slight declines in American growth when the world just had the best decade ever."  Is it then wrong to focus on any other problems at all?  I also was one of the first people to make the "best decade ever" argument, which I still accept.)  Medians also matter for the political climate, even though the median earner is not exactly the median voter.  Adam Smith's welfare economics was basically that of the median, a point which David Levy has made repeatedly.

I'm also being called a "pessimist" a lot.  Yet in my view our current technological plateau won't last forever.  That's probably more optimistic than the Hacker-Pierson approach, which requires a Progressive revolution in economic policy (unlikely), although it is not more optimistic than denying the relevance of the numbers.

I'll soon blog some remarks on changing household size as another attempt to avoid confronting the facts about slow median income growth.

Counting and Adding

Very enjoyable lecture on partition numbers. Deep but accessible, especially first half. Hat tip: The Endeavour.

The wisdom of Rocco Landesman

Speaking at a conference about new play development at Arena Stage in Washington on Thursday, Mr. Landesman, the chairman of the National Endowment for the Arts, addressed the problem of struggling theaters. "You can either increase demand or decrease supply," he said. "Demand is not going to increase, so it is time to think about decreasing supply."

Here are some of the responses from the sector:

"What does he mean there's too much supply?!?" wrote Trisha Mead, the public relations and publications manager at Portland Center Stage in Oregon. "What does he mean we can't increase demand?!? Who determines which theater companies are wheat and which are chaff?!?" In another post, Durango Miller, a playwright and director, said: "Why not just increase funding? Maybe the N.E.A. is outdated and should be replaced by another system for funding the arts in the United States. Or maybe the people who are running the N.E.A. should be replaced."

To conclude, there is good reason to adjust the long-term US productivity growth rate downwards.

My favorite things Egypt

1. Novel: I like all of the Mahfouz I have read, but the Cairo Trilogy is the obvious pick.  Here is a very useful list of someone's favorite Egyptian authors and novels.

2. Musical CD: The Music of Islam, vol.1: Al-Qahirah, Classical Music of Cairo, Egypt.  The opening sweep of this is a stunner, and it shows both the Islamic and European influences on Egyptian music.  Musicians of the Nile are a good group, there is Hamza El Din, and there is plenty of rai.  What else?  I can't say I actually enjoy listening to Um Kalthoum, but her voice and phrasing are impressive.

3. Non-fiction book, about: Max Rodenbeck, Cairo: The City Victorious.  Few cities have a book this good.  There is also Dream Palace of the Arabs and Tom Segev's 1967.  Which again is the really good book on the 1973 War?

4. Movie, set in: Cairo Time.  This recent Canadian film avoids cliche, brings modern Cairo to life, and is an alternative to many schlocky (but sometimes good) alternatives, such as The Mummy, Death on the Nile, Exodus, Raiders of the Lost Ark, and so on.  There is Agora.  Egyptian cinema surely has masterpieces but I do not know them.  If you're wondering, for books, I could not finish Norman Mailer's Ancient Evenings.

5. Favorite food: I was impressed by the seafood restaurants on the promenade in Alexandria.  Food in Cairo did not thrill me, though I never had a bad meal there.

6. Philosopher: Must I say Plotinus?  I don't find him especially readable.

7. City: I enjoyed Alexandria, but I can't say I liked Cairo beyond the museum (much better than any Egyptian collection outside of Egypt) and the major mosques.  The Sphinx bored me.  The air pollution prevented me from walking for more than an hour and there was cement, cement. and more cement.  The ride between Cairo and Alexandria was one of the ugliest, most uninspiring journeys of my life.  The Egyptians were nice to me but I never had the sense that anything beautiful was being done with the country.  Let's hope that changes.

8. Opera, about: Philip Glass, Akhnaten.  But wait, there's also Aida, with Callas.  And there's Handel's Israel in Egypt.  Handel set a lot of his operas in Egypt, including Berenice and Giulio Cesare.

Diane Rehm is Egyptian-American but I don't know her show.  The new biography of Cleopatra is smooth but the narratives made me suspicious.  Was Euclid Egyptian?

Egypt facts of the day

The Market Vectors Egypt Index (EGPT) ETF is down 20% since Jan. 14 and down 2.9% today on more than six times the daily average volume. Egypt's credit-insurance costs have also spiked. According to Markit, a data provider, a credit-default swap to insure $10 million of Egyptian sovereign debt over five years has spiked 33% to $405,000. (Update: the CDS cost has jumped to $450,000 since this post was first made.) It may surprise, given what you see on TV, but that's still cheaper than similar insurance for Portugal, Ireland and Greece.

The article is here.  And:

The Nasdaq Israel Index (ISRQ) is down 1.2% today and 3% in the past 10 days.

*The Order of Public Reason*

That is the title, the author is Gerald Gaus of U. Arizona, and the subtitle is A Theory of Freedom and Morality in a Diverse and Bounded World.  This is a big and ambitious work, broadly in the liberaltarian tradition, mixing Rawls and Hayek, pondering the implications of disagreement, and experimenting with the idea that morality itself has a coercive element.  It is Gaus's attempt to lay out the proper foundations for a liberal society and he summarizes the hard-to-summarize book a bit here.

Also new on the market is Ronald Dworkin's Justice for Hedgehogs.  I like the title and I like most of his previous books, but I am not finding this one rewarding to read.  Here is one previous debate on related material.
