Frankly, I'm confused. Robert H. Frank, the excellent Cornell economist, writes about taxes and income distribution, recently published a new book, The Darwin Economy, and has a regular blog in the New York Times (http://www.robert-h-frank.com/timescolumn.html). Frank Rich, who until his recent retirement was a fine columnist for the Times, may have started as a theater critic, but ended his stint on the Op-Ed page with essays on finance and the public interest like “The Tea Party Wags the Dog” and “At Last, Bernie Madoff Gives Back” (http://topics.nytimes.com/top/opinion/editorialsandoped/oped/columnists/frankrich/index.html). To top it off, Robert Frank, who writes about wealth for the Wall Street Journal (http://blogs.wsj.com/wealth/), has authored two recent books, Richistan (2007) and The High-Beta Rich (2011), about the meteoric trajectories of the spectacularly well off in 21st century America. And, as if willfully to confound the issue, Robert goes so far as to cite an earlier book, “The Winner-Take-All Society, by Robert H., no relation” (p. 18), in High-Beta. Clear? No wonder I’m confused.
In an effort at least to distinguish Robert Frank from Robert H. Frank, I’ve just finished High-Beta and have ordered a copy of Darwin Economy.
OK. So what Frank is on about is that the increasing concentration of income at the top end of the income distribution (see my last couple of posts, “Trick or Treat” and “PS…”) and the increasing volatility of the incomes and spending patterns of the top few percentiles mean that our economy is itself more and more a volatile reflection of their experience. He draws heavily on the work of Parker and Vissing-Jorgensen to document the increasing magnitude since WW II of income swings in the top 1% as compared to the rest of us. In the days of my youth, the income streams of the wealthy were much less volatile than the average (beta < 1), but over time that has changed as income increases have become more concentrated and the income of the richest have come to depend less and less on manufacturing and more and more on financial instruments. In the 1%, beta is about 2; in the rarified top 0.01%, it’s over 3.
