Thoughts On Inequality
Posted by Matt Zeitlin on June 20, 2008
From Ezra Klein, comes this paper by Ian Dew-Becker and Robert Gordon exploring the rise of inequality. Or more accurately, two types of inequality. One, the seperation of the top decile (10%) from everyone else, and two, the rise of inequality within that top decile. Of course, these two phenomena seem related, but they really aren’t. The factors driving the great accumulation of wealth among the tippity-top are different, according to Gordon and Dew-Becker, than what’s responsible for the 90th percentile running away from everyone else - skills based technological change, or more specifically, increased returns to managers:
During 1979–97 fully half of the growth in the college wage premium can be attributed to the increased relative wage of the group called “managers,” and only 17 percent to the computer-related occupational groups. The Autor et al. three-way distinction would place computer programmers and many types of engineers in the middle, rather than high category, as jobs subject to outsourcing and not benefiting from a rapid growth of demand relative to supply…
It’s hard to see why this type of inequality is ipso facto objectionable. It seems to be purely an effect of markets working, basically, as they ought to. The problem is that in the past, when the college wage premium increased, more people would go to college and it would balance back out. So I don’t think our efforts here should be focused at decreasing inequality, per se, but instead at trying to increase opportunities for people to get that skills-based wage premium, and if not that, than increased unionization and raising the minimum wage could help boost incomes for everyone else.
The second inequality is that within the top decile. This isn’t driven by SBTC, decreased unionization or a flagging minimum wage. They identify two main factors: the “superstar effect” and clubby relationships that ensure high CEO pay:
Superstars include the top members of any occupation that provides disproportionate rewards to the first-best as contrasted with the second-best. The superstar phenomenon has at its core the magnification of audiences, the fact that a single performance can be witnessed by an audience of one person or ten million people, depending on the perceived attraction and talent. The second category includes law partnerships, investment bankers, and hedge fund managers, where there is no obvious analogy to audience magnification but where there are steep wage premia for the very best in an occupational niche, and where it is apparent that incomes are highly market-driven.
The most contentious question regards the third category, top executives in public corporations. The core distinction is that CEO compensation is chosen by their peers in a system that gives CEOs and their hand-picked boards of directors, rather than the market, control over top incomes. The idea that managers, rather than stockholders, control directors goes back to Berle and Means (1932). This idea that the principal-agent control of stockholders should be reversed has been applied fruitfully by such authors as Bebchuk and Fried (2004). They argue that managerial power lies behind some of the outsized gains in CEO pay.
Although there should certainly be some reforms relating to CEO compensation, it seems like the biggest driver of inequality in the highest decile is market based. The Nation’s special inequality issue has a great chart showing that the compensation of the top 5 hedge fund managers is 43 times greater than that of the top 5 CEOs. So, Gordon and Dew-Becker ultimately conclude that there is only one mechanism which can reduce top-decile-inequality: tax policy.
This, I think, is a central question for liberals. All left-of-center folk agree that there should be higher taxes on the rich and that we should be promoting policies which will expand opportunity for the bottom 90 percent. This means increased educational access, universal health care, more union-friendly policies and so on and so forth. But even if we were to implement a fairly progressive agenda tomorrow, we’d likely see little decrease in pre-tax inequality (or even post-tax inequality). That’s because the forces driving the extreme inequality we see today have little to do with decreased unionization or the college wage premium being so high. They have to do with the fact that individuals can make extremely large amounts of money in the financial markets. And this is where the split will occur.
The Nation argues that the existence of concentration wealth is, in and of itself, a bad thing. The reasoning is actually fairly persuasive. It will be impossible to enact those reforms I listed above when people like Bruce Kovner can make billions of dollars and fund AEI and the Manhattan Institute to agitate against those progressive ideas. In short, with concentrated wealth comes intrinsic conservatism, as those wealthy people will inevitably use their great clout to preserve their position. An so there is a feedback loop, whereby ideologues/rich people implement policies that make them richer (deregulation, lower marginal tax rates, union busting etc) which then allows them to influence the system to preserve those policies to ensure their high position. The reduction of concentrated wealth thus becomes “the reform that makes all other reforms possible.”
Now, I don’t agree with this position, because I think the measures necessary to truly disperse or eliminate concentrated wealth would be bad for growth, but it’s one that has lots of support and will only gain more.
So, for now, as inequality has exploded under a Republican president, nearly everyone from the center-left to the progressive left is convinced that something ought to be done. But expect the debates to become heated once modest tax increases don’t reduce top decile inequality all that much.
