A follow-up to the Autor post below this one. This is by David Howell, a professor of economics and public policy at The New School in New York City:
The links between institutions and shared growth, Washington Center for Equitable Growth: ...since the 1980s, U.S. economic growth failed to produce enough jobs, and equally important, enough "decent jobs, " which I defined as those paying adequate wages with adequate hours of work. ...
What happened to shared growth? Most economists continue to explain the explosion of earnings inequality with conventional supply-and-demand stories, in which worker compensation is believed to accurately reflect the contribution workers make to production. Thus, in this view, CEOs and financiers have received skyrocketing salaries, especially since the mid-1990s, because they are now contributing dramatically more to their firms and to the economy as a whole.
Similarly, the bottom 90 percent have seen stagnant and falling wages because they've fallen behind in the "race between education and technology." The computerization of the workplace requires greater cognitive skills, but workers have not kept up, as indicated by the slowdown in college graduation rates. Assuming (nearly) perfectly competitive markets, the explosion in wage inequality in this view must reflect a similarly explosive increase in skill mismatch (too many low skill workers, too few high skill ones).
Such arguments leave little or no room for labor market institutions and public policies in the determining changes in the distribution of earnings up and down the income ladder. An alternative view is that institutionally-driven bargaining power is a critical piece of the story, whether it is the noncompetitive "rents" earned by top managers and financiers, or the collapsing power of hourly wage employees. As Thomas Piketty argues in "Capital in the Twenty-First Century:"
In order to understand the dynamics of wage inequality we must introduce other factors, such as the institutions and rules that govern the operations of the labor market in each society [and explain] the diversity of wage distributions we observe in different countries at different times.
All rich countries face challenges from technology and globalization, but only the United States and the United Kingdom show inequality rising to extreme levels.
In order to understand wage inequality and unshared productivity growth in the United States, we must take a much closer look at the ways in which institutions affect labor market outcomes. ...

Be Calm, Robots Aren't About to Take Your Job, MIT Economist Says: David Autor knows a lot about robots. He doesn't think they're set to devour our jobs. ... His is "the non-alarmist view"...
Mr. Autor's latest paper, presented to a packed audience at this year's meeting of central bankers at Jackson Hole, Wyo., emphasized how difficult it is to program machines to do many tasks that humans find often easy and intuitive. In it, he played off a paradox identified in the 1960s by philosopher Michael Polanyi, who noted that humans can do many things without being able to explain how, like identify the face of a person in a series of photographs as they age. Machines can't do that, at least not with accuracy.
This is why big breakthroughs in automation will take longer than many predict, Mr. Autor told the bankers. If a person can't explain how they do something, a computer can't be programmed to mimic that ability. ...
To Mr. Autor, polarization of the job market is the real downside of automation. He calculates middle-skill occupations made up 60% of all jobs in 1979. By 2012, this fell to 46%. The same pattern is visible in 16 European Union economies he studied.
The upshot is more workers clustered at the extremes. At the same time, average wages have stagnated for more than a decade. He attributes this to the loss of all those relatively good-paying middle-range jobs, as well as downward pressure on lower-skilled wages as displaced workers compete for the lesser work. ...
I've been arguing for a long time that in coming decades the major question will be about distribution, not production. I'm not very worried about stagnation, etc. -- we'll have plenty of stuff to go around. I'm worried about, to quote the title of a political science textbook I used many, many, many years ago as an undergraduate, "who gets the cookies?" not how many cookies we're able to produce So I agree with Autor on this point:
Mr. Autor ... added, "If we automate all the jobs, we'll be rich—which means we'll have a distribution problem, not an income problem."

Jason Furman, Ron Shadbegian, and Jim Stock:
The cost of delaying action to stem climate change: A meta-analysis, Vox EU: Summary The cost of delaying climate action has been studied extensively. This column discusses new findings based on a meta-analysis of published model runs. A one-decade delay in addressing climate change would lead to about a 40% increase in the net present value cost of addressing climate change. If anything, the methodology used in this analysis could understate the cost of delay. Uncertainty and the possibility of tipping points provide a motivation for more action as a form of insurance against worse outcomes.

Me, at MoneyWatch:
What's a fair tax rate? It depends: How progressive should the U.S. tax system be? Answering this question requires an assumption about what's fair in terms of tax burdens across income groups. But people differ widely on what they consider fair. Therefore, fairness isn't something economic theory can address. Instead, a principle of fairness must be assumed.
