We assess the long-run growth effects of rising longevity and increasing the retirement age when growth is driven by purposeful research and development. In contrast to economies in which growth depends on learning-by-doing spillovers, raising the retirement age fosters economic growth. How...

This paper investigates the relevance of government purchasing behavior for innovation-based economic growth. We construct a parsimonious Schumpeterian growth model in which demand from the public sphere can effectively alter the economy's rate of technological change. We incorporate results of...

Economic development in industrialized countries is characterized by rising per capita GDP, increasing life expectancy, and an ever greater share of the population living in cities. We explain this pattern within a regional innovation-driven economic growth model with labor mobility and a...

Since governments can influence the demand for a new abatement technology through their environmental policy, they may be able to expropriate innovations in new abatement technology ex post. This suggests that incentives for environmental R&D may be lower than the incentives for market goods...

Dean Baker and Adriane Fugh-Berman have published a critique of a study I performed in 2007, entitled Why has longevity increased more in some states than in others?" One of the conclusions I drew from that study was that medical innovation accounts for a substantial portion of recent increases...

We construct a theory of intergenerational preference transmission that rationalizes the choice between alternative parenting styles (related to Baumrind 1967). Parents maximize an objective function that combines Beckerian and paternalistic altruism towards children. They can affect their...

How does technical progress affect long-term unemployment? The relationship between long-term unemployment and the rate of growth attributable to technical progress is evaluated in a growth-matching-model with heterogeneous jobless workers and with endogenously determined long-term unemployed...

Production often causes pollution as a by-product. Once pollution problems become too severe, regulation is introduced by political authorities which forces the economy to make a transition to cleaner production processes. We model this transition as a change in general purpose technology (GPT)...
