New NBER Working Paper: "Work of the Past, Work of the Future" by David Autor

From a new NBER Working Paper, "work of the Past, Work of the Future," by David Autor 

Abstract:

Labor markets in U.S. cities today are vastly more educated and skill-intensive than they were five decades ago. Yet, urban non-college workers perform substantially less skilled work than decades earlier. This deskilling reflects the joint effects of automation and international trade, which have eliminated the bulk of non-college production, administrative support, and clerical jobs, yielding a disproportionate polarization of urban labor markets. The unwinding of the urban non-college occupational skill gradient has, I argue, abetted a secular fall in real non-college wages by: (1) shunting non-college workers out of specialized middle-skill occupations into low-wage occupations that require only generic skills; (2) diminishing the set of non-college workers that hold middle-skill jobs in high-wage cities; and (3) attenuating, to a startling degree, the steep urban wage premium for non-college workers that prevailed in earlier decades. Changes in the nature of work—many! of which are technological in origin—have been more disruptive and less beneficial for non-college than college workers.

The debate on what to do about income inequality intensifies

Or, is the debate shifting to one about semantics?

From Fatih Guvenen and Greg Kaplan in a new NBER paper.

We revisit recent empirical evidence about the rise in top income inequality in the United States, drawing attention to four key issues that we believe are critical for an informed discussion about changing inequality since 1980. Our goal is to inform researchers, policy makers, and journalists who are interested in top income inequality. Our analysis is based on a reexamination of publicly available detailed statistics from two administrative data sources: (i) Internal Revenue Service (IRS) data on total incomes (labor income plus capital income), reported in Saez (2012), and (ii) individual-level micro data on labor income (wage plus self-employment income) from the U.S. Social Security Administration (SSA)  reported in Guvenen et al. (2014).

One key take-away:

Put simply, so far in the 21st century, all the action in top income shares has been S-corporation income at very, very high income levels.
