The Decision to take up Adult Education: a Dynamic Programming Analysis
Justin van de Ven and Martin Weale
National Institute of Economic and Social Research
• Why don’t more people participate in life-long learning?
• Educational upgrading leads to higher pay and better employment prospects.
• We consider men upgrading from level 2 (qualifications above GSCE) to level 4 (higher education).

Are the uncertain benefits from upgrading a deterrent?
• The increase in earnings associated with upgrading is not statistically significant at a 5% level.
• But the uncertainty surrounding the effects of upgrading suggest that 90% confidence limits for its individual effects in multiplying up earnings are 0.52 to 1.92.
• A high chance of upgrading going wrong.
A Structural Analysis (i)
• Welfare comes from consumption and leisure• Assume people maximise their expected life-
time welfare but are risk-averse• £1 is better than equal chances of getting 50p or
£1.50. • Life-long learning has costs in terms of fees and
leisure time given up.• It yields uncertainty benefits in terms of better
pay and employment prospects.• Is this uncertainty enough of a deterrent.
A Structural Analysis (ii)
• Choose parameters to define welfare function so as to match observed consumption and labour supply decisions over the life-course as closely as possible.
• Implies a reasonably strong degree of risk-aversion.
• Earnings rise sharply for people in their 20s and more slowly to about 45; then fall off
• But there is a strong random element.
A Structural Analysis (iii)
• Simulate a panel of 10000 people moving through the life course.
• At each age they can decide how much to spend and whether to work full-time, part-time or not at all.
• They can also decide whether to upgrade their qualifications or not. Upgrading is possible only once.
• Observe the number of people deciding to upgrade by age.
Costs of Education
• University fees introduced at £1000 in 1998/9; currently £9000
• Many higher education sub-degree courses are much cheaper and take one or two years.
• Full-time education makes full-time work impossible but does allow part-time work.
• Part-time study is compatible with full-time work but leaves little spare time.
• Assumed two years of full-time study or three years of part-time study.
Drop-out Rates
• 15-17% of mature students drop out after the first year
• Resumption rates are under 20%
• 37% of part-time students under 30 dropped out and 34% of those aged 30+
• No information on failure; we explore the role of a subjective risk of failure.

Conclusions
• Risk is a factor affecting the take-up of life-long learning.
• But both uncertainty about earnings and fees go only a part of the way to explaining low participation.
• High subjective risks of failure are needed to account for observed participation rates.
