Do We Need More Scientists and Engineers? The National Value of Science Education Wellcome Trust Conference York, UK: 17 September 2007 Michael S. Teitelbaum Vice President Alfred P. Sloan Foundation, New York [email protected] Concerns in common Losing lead in R&D? Shortages of scientists/engineers? Student interest in science declining Proposed solutions in common Combat decline in basic science lead Combat “shortages” of S & Es US: double basic research $ (2X in 7 yrs)? EU: increase R&D to 3% of GDP (Lisbon) More domestic students Increase foreign inflows Combat low domestic student interest More and better teachers; curricula Challenge 1: losing R&D lead? Yes, but overstated “The report of my death is an exaggeration." (Mark Twain, 1897) R&D prowess increasing: US, EU, Japan Europe dominant until WW II, U.S. later But relative decline is inevitable… …as other countries catch up (India, China) …investments by US/EU co’s, universities Challenge 2: “Shortages”? A long and embarrassing history in US Late 1980s: led by then-Director of NSF Late 1990s: IT firms (IT “shortages”) Forecasts of “looming shortfalls” Congressional investigation few years later Success: 3x visas from 2001--then IT Bust Now: employers, National Academies Evidence?: labor markets slack… With variations over time, and by field Consistent w/ tight labor markets in some specialties (especially new & growing) But, if anything, data point to surpluses RAND on late 90s high-tech boom in US: rising S&E unemployment that “while the overall economy is doing well, is a strong indicator of developing surpluses of workers, not shortages.” Since: IT, telecom, biotech bubbles burst Why “shortage” claims perennial? Interest groups making their case Employers Universities Government funders Immigration lawyers (esp. US) Intend no harm; promoting interests But politicians, journalists often believe Governments often fail to analyse Challenge 3: improve schools? Critical, but for more than S&E numbers (annoying fact: S&Es less than 5% of workforce) Why? Basic science/math now essential for all Needed in most non-S&E occupations As important as literacy in 20th C productivity, key for high-wage economies Shall we blame schools? ROSE study data: very interesting Inverse relation: country wealth with student interest in science careers School quality, or alternative careers? S&E supply without demand? Demand side often ignored – surprising! S&Es need employment, labs Requires large personal investment S&E careers falling behind others Demand essential Alas, many unknowables Many shocks, long lags Government S&E budgets: unpredictable Military procurement: erratic, unpredictable Private markets: speculative booms & busts IT, aerospace, biotech, telecom Forecasts have failed And now harder (offshore outsourcing) (“Accurate forecasts have not been produced”- National Research Council, 2000) Caution: labor markets ahead Pumping up supply w/o demand is: unwise & wasteful ultimately ineffectual Assess: how attractive are careers? Assess: does increased migration & offshoring reduce domestic interest? Needed: honest “systems” perspective Needed: degrees connected to demand If want more domestic supply, how? Lots of interested university applicants EU: can directly influence S&E univ “slots” US: less control; students can change fields 1/3 entering undergraduates intend S&E degree But retention/completion low <1/2 intending freshmen complete S&E degree 1/3 shift to other fields ~1/5 drop out Source: HERI, UCLA surveys, recent years Increase from <50% to 60-70%? What not to do… “Supply-side” actions only Encourage more students… …without parallel career demand US biomedical research budget doubled 1998-2003 (from $14 to 27 billion) A nasty “hard landing” now underway Now: effort to double physical sciences NIH Budget BUDGET AUTHORITY FY 1977 – FY 2007 (Current vs. Constant 1977 Dollars Using BRDPI as the Inflation Factor)(Dollars in Billions) $30 $25 $20 $15 $10 $5 2007 2006 2005 2004 2003 2002 2001 Constant Dollars 2000 1999 1998 1997 1996 1995 1994 1993 1992 Current Dollars 1991 1990 1989 1988 1987 1986 1985 1984 1983 1982 1981 1980 1979 1978 1977 $0 Biomedical PhDs Age 35 or Younger Number 20,000 15,000 10,000 5,000 0 1993 1995 1997 1999 2001 Year Age 35 or Younger In Tenure-track Jobs Source: Survey of Doctorate Recipients, NSF.

Benefit to nation NOT automatic Results are “public goods” Findings published, exploitable by all Benefits are significant, but global Universities & companies: globalizing Challenge: maximize domestic return? Goals for schools’ science/math? Popular focus on “shortages” is weak Little evidence of shortages Plenty of university applicants Strong case Important drivers of national wellbeing Science/math critical to being “educated” Informed citizenry in technological world Key to increasing national productivity Thank you! Comments/questions welcome: Michael S. Teitelbaum Vice President Alfred P. Sloan Foundation [email protected] NRC Committee Recommendations Limit growth of grad student numbers Provide students good career information Improve/broaden graduate education Enhance independence of postdocs Encourage alternative career paths What happened? NIH budget doubled 1998-2003 Number of PhDs in US <35 increased Postdocs trained outside US increased Hiring patterns: slight increase, lagged Summary Total academic positions up 33% in decade But heavily concentrated in non-tenure track Non-tenure track up over 70% Tenure-track up 20% Proportions <35 in tenure track: unchanged 1993: 10.4% 2003: 10.3% (but was 6.9% in 2001) Fewer very-extended postdocs Non-academic employment up more than academic Unemployed and not-in-labor-force: also grew Downside risks of raising supply Lynn and Salzman, Issues in Science & Technology, National Academies, Winter ‘06 Unemployment rate, by selected occupations: 1983–2002 Often missed: S&E occ’s small % Can we learn from history? [Source: Paula Stephan, 2007 Harvard seminar] 1996: NRC committee on trends in early careers of life scientists Concerns: PhD #’s up, but job market flat Indicators: Increased time to degree Increase in number postdocs & postdoc length Decreased probability of tenure track position Declining NIH support for young investigators Num be r o f P h.D .s C o nfe rre d in the B io m e dic a l S c ie nc e s 1 9 6 3 -1 9 9 6 7200 4800 3600 2400 1200 95 19 93 19 91 19 89 19 87 19 85 19 83 19 81 19 79 19 77 19 75 19 73 19 71 19 69 19 67 19 65 19 63 0 19 T o ta l P h .D .s 6000 Y ears N um b e r o f P h.D .'s Source: NRC Report M edian Tim e to Degree and Age at Degree 8.5 (U S L ife-Scien ce Ph .D .s in th e B io m ed ical Scien ces) 32 8 7.5 31 T ime to Degree 7 30.5 6.5 6 30 5.5 29.5 5 M edian Age at T ime of Degree 31.5 29 4.5 4 28.5 1970 1971 1972 1973 1974 1975 1976 1977 1978 1979 1980 1981 1982 1983 1984 1985 1986 1987 1988 1989 1990 1991 1992 1993 1994 1995 1996 Ye a r Tim e to D e g re e M e d ia n A g e a t Tim e o f D e g re e Source: NRC Report NIH grants to 35 and younger 1993 ~380 awards 1994 ~410 1995 ~350 1996 ~340 1997 ~330 1998 ~330 Average age at first independent award 1980: 37 1990 39.5 Continued to rise during 1990s.

Increase retention/completion Address reasons 1/2 intending don’t complete Poor K-12 preparation? Less supportive cultures? Teaching quality? “Weeding-out”? Grading curve differences? Career prospects seen as poor? NB: CS rose sharply 1990s, down since bust
