    Growth and Education
    (World Bank, Washington, DC, 2009) Aghion, Philippe
    Does education matter for growth? Which type of education investment (primary, secondary, or tertiary) matters most? Is there a relationship between growth or innovation and the governance of higher education? This paper surveys recent attempts at answering these questions. It first contrasts the 'Lucas approach,' whereby growth is affected by the accumulation of human capital, with the 'Nelson?Phelps approach,' whereby growth is affected by the stock of human capital and by its interaction with the underlying process of technological innovation. Then the paper argues that growth in countries that are close to the world technological frontier benefit more from tertiary education, whereas countries that lie below the frontier benefit more from primary and secondary education. Finally, the paper discusses the relationship between innovation and the governance of universities.

    From Growth Theory to Policy Design
    (World Bank, Washington, DC, 2009) Aghion, Philippe; Durlauf, Steven
    This paper focuses on how growth theory can guide growth policy design. It first argues that policy matters for growth, in particular when policy variables are interacted with country?specific variables (financial development, institutional environment, technological development, and so forth). Second, it argues that the Schumpeterian paradigm does a better job at delivering policy prescriptions that vary with country characteristics. Third, it discusses the advantages and drawbacks of growth regression analysis. Finally, it briefly describes and then questions the recently proposed 'growth diagnostic' approach.
