Who I am.
I am an economist, retired from teaching and department meetings but not much else. I am currently a lecturer in the Department of Health Care Policy, Harvard Medical School, where I work on technology's impact on jobs and living standards and on the economics of radiology. I also organize the CSAIL/Economist Seminar series at MIT bringing together computer scientists and economists to better understand computerized work. l am married to Katherine Swartz, an economist at the Harvard School of Public Health. We have two children Dave (and his wife Kelly) and Marin (and her husband Joseph) and we have a three outstanding grandchildren: Andrew (22 months as of January 2015), Ben (17 months) and Emma (5 months). Before coming to MIT in 1992, I taught for ten years at Cal-Berkeley and eleven years at the University of Maryland at College Park and worked for four years at the Urban Institute in Washington DC.
With Dr. Max Rosen of UMass Memorial Hospital/Medical School, I am currently finishing a book manuscript on an economic history of U.S. medical imaging. I am starting a project with Professor Dana Remus of UNC School of Law exploring computers' impact on lawyers and the practice of law.
A new working paper 'Dropouts, Taxes and Risk: The Economic Return to College under Realistic Assumptions" (with Alan Benson and Raimundo Esteva) demonstrates that standard estimates of the rate of return to college are based on best case assumptions that sometimes overstate returns and, more important, obscures differences in returns among institutions. More realistic assumptions can reasonably inspire caution among some students and their parents depending on what type of institution they attend. My paper, Dancing with Robots is coauthored with Richard J. Murnane (The Third Way Foundation) examines the skills needed in a job market that has been reshaped by computerized work and offshoring.
The "Sharp Slowdown in Growth of Medical Imaging" co-authored with David Lee of GE Healthcare, was published in the August 2012 edition of Health Affairs and documents how policy has managed to slow the growth of advanced imaging utilization (Abstract). Earlier papers include "Offshoring Radiology Services to Inidia" (British Journal of Industrial 'Relations), with Kyoung He Yu, "Computers and the Supply of Radiology Services" (Journal of the American College of Radiology) in which I argued that computers were increasing competitive pressure on radiologists and "Computers, Conversation, Utilization and Commoditization" (Americal Journal of Roentology) where I trace the impact of digitized imaging on the radiologost's job and the radiology job market.
Wage Stagnation and Economic Inequality
About seven years ago, Peter Temin and I completed two book chapters explaining the development and subsequent collapse of the economic institutions that helped to achieve an equitable distribution of economic growth in the years between World War II and the 1980s. A working paper version of the argument is available here. A short version of the argument was given as the first Bernie Saffran Memorial Lecture at Swarthmore College, November 15, 2007.
