In this paper a two-sector growth model allowing indeterminacy to occur at relatively mild degrees of increasing returns is developed. It is shown that these economies of scale need only be present in one sector of the economy (investment). This feature of the model, therefore, builds on...

I exploit heterogeneous impulse responses at the household level due to limited stock market participation to provide novel evidence on the degree of nominal rigidities. A number of studies show that positive technology shocks reduce aggregate hours. The finding is often interpreted as evidence...

We analyze the effects of neutral and investment-specific technology shocks on hours worked and output. Low frequency movements in hours are captured in a variety of ways. Hours robustly fall in response to neutral shocks and robustly increase in response to investment specific shocks. The...

We analyze the effects of neutral and investment-specific technology shocks on hours worked and unemployment. We characterize the response of unemployment in terms of job separation and job finding rates. We find that job separation rates mainly account for the impact response of unemployment...

An informal model is described that leads to multiple macroeconomic equilibria as a consequence of random variation in the relative amounts of technological change for new and existing goods. The novel observation is that the rate of introduction and market penetration of new goods vis-a-vis...

This paper asks two questions. First, can we detect empirically whether the shocks recovered from the estimates of a structural VAR are truly structural? Second, can the problem of nonfundamentalness be solved by considering additional information? The answer to the first question is "yes" and...

After a long period of catch-up growth that began after the Second World War, France has now reached a technological frontier in many sectors of its economy. Why is it then that the French economy ranks so low in various rankings of the world's most innovative economies? Why is it so difficult...

Conventional R&D-based growth theory suggests that productivity growth is positively correlated with population size or population growth, an implication which is hard to see in the data. Here we integrate micro-founded fertility and schooling into an otherwise standard R&D-based growth model....

This paper surveys the empirical and theoretical link between education and growth in the growth process of Asian countries. Particular attention is paid to the link between education and productivity, and to models that characterize key features of growth processes of Asian countries. Empirical...
