We set up a three-period overlapping generation model in which young individuals allocate their time to schooling and work, healthy middle aged individuals allocate their time to leisure and work and their income to consumption and savings for retirement, and old age individuals live off their...

Workers in the US and other developed countries retire no later than a century ago and spend a significantly longer part of their life in school, implying that they stay less years in the work force. The facts of longer schooling and simultaneously shorter working life are seemingly hard to...

For most of human history there existed a well-educated and innovative elite whereas mass education, market R&D, and high growth are phenomena of the modern period. In order to explain these phenomena we propose an innovation-driven growth model for the very long run in which the...

We set up a simple overlapping generation model that allows us to distinguish between life expectancy and active life expectancy. We show that individuals optimally adjust to a longer active life by educating more and, if the labor supply elasticity is high enough, by supplying less labor. When...

We analyze the di fferential growth e ffects of basic research, applied research, and embodied human capital accumulation in an R&D-based growth model with endogenous fertility and endogenous education. In line with the empirical evidence, our model allows for i) a negative association between...

We analyze the differential growth effects of basic research, applied research, and embodied human capital accumulation in an R&D-based growth model with endogenous fertility and endogenous education. In line with the empirical evidence, our model allows for i) a negative association between...

We analyse the long-run equilibrium and adjustment dynamics in three popular models of economic growth when property rights are absent. The results are compared to the outcome in the corresponding economy with secure property rights.
