  1. Life in Shackles? The Quantitative Implications of Reforming the Educational Financing System B. Heijdra, L. Reijnders and F. Kindermann

  2. Motivation ◮ Obtaining college education requires large investment of both time and money. ◮ To facilitate access to education, most governments have instituted education financing systems. ◮ System design varies substantially across countries ◮ US: Mortgage Loans ◮ Australia: Income Contingent Loans ◮ Netherlands: Basic Grants financed from tax money

  3. Motivation ◮ The problem of the US mortgage loan system: ◮ It guarantees wide access to tertiary education. ◮ BUT: College students may end up with lots of study debt. ◮ Might be especially painful when a graduate is unlucky in the labor market.

  4. Motivation “. . . student loan systems [. . . ] are often badly designed for an extended period of high unemployment. In contrast to the housing crash the risk from student debt is not of a sudden explosion in losses but of a gradual financial suffocation. The pressure needs to be eased.” The Economist (October 29th, 2011)

  5. Motivation

  6. Potential Solutions ◮ Theoretical literature promotes income dependent financing schemes to insure educational risks. ◮ Private arrangements: ◮ Students sell a share of their future earnings to investors. ◮ Equity investment idea dates back to Friedman. ◮ Comes with some complications: default, costly income verification, ... ◮ Public arrangements: ◮ Income dependent education financing system. ◮ Government has the ability to tax college graduates.

  7. In This Paper ◮ Focus on public arrangements. ◮ Quantitative analysis of different financing schemes. ◮ Start from mortgage loans system in the US. ◮ Reform system so that grants to students are financed from ◮ comprehensive taxes or ◮ graduate taxes or ◮ degree-specific taxes.

  8. Preview on Results ◮ Move to graduate or degree-specific tax scheme increases aggregate welfare. ◮ Risk-sharing benefits and positive education incentives outweigh labor-supply distortions. ◮ Reforms lead to considerable transitional dynamics.

  10. A Quantitative Model with Education Decisions

  11. The Overlapping Generations Framework ◮ Overlapping generations of heterogeneous individuals. ◮ Demographics: ◮ lifespan is certain ◮ population grows at constant rate ◮ Households: ◮ choose how many years to stay in higher education ◮ choose labor supply in the working phase ◮ create human capital through learning-by-doing ◮ decide about consumption and savings

  12. Components of individual heterogeneity/risk ◮ Educational ability θ ∈ [ 0, 1 ] . ◮ On-the-job learning ability ◮ γ ∈ { γ l , γ h } ◮ correlated with θ ◮ Individual labor productivity ◮ η ∈ { 0, η l , 1, η h } ◮ evolves stochastically over life cycle with autocorrelation

  22. Education Financing System, Government and Firms ◮ Subsidized Mortgage Loan System: ◮ Each student has to pay back her individual loan. ◮ Υ u , t ( E , w t η h l ) is calculated such that the PV of repayments equals the PV of loan uptake. ◮ Interest payments are deductible from income taxes. ◮ Government taxes consumption and income to finance ◮ public consumption ◮ unemployment benefits ◮ Firms produce in competitive markets using capital and labor with Cobb-Douglas technology.

  23. Calibration

  24. Calibration Strategy ◮ Two step calibration procedure: 1. Take some parameters from literature or directly from data. 2. Calibrate remaining parameters to match important target moments from the data.

  25. Calibration Strategy Excerpt of Step 1 ◮ Risk aversion of ζ = 4 . ◮ Autocorrelation of productivity shocks ρ η = 0.821 . ◮ Unemployment probabilities by education from CPS. ◮ Annual student loan uptake to average income 0.238 ◮ Grace period before loan repayment of 4 years. ◮ Total repayment time of 15 years.

  26. Calibration Strategy Excerpt of Step 2 ◮ Capital to output ratio. ◮ Consumption and income tax revenue. ◮ Education composition of the population from CPS. ◮ Average labor productivity profiles by education. ◮ Old-age labor force participation. ◮ Variance of income growth rates. ◮ Variance of log labor earnings by age.
