This paper extends public spending-based growth theory along three directions: we assume that exogenous and constant technological progress does exist and that both population change and the ratio of government expenditure to income follow a logistic trajectory. By focusing on the choices of a...

We analyze the effects of government spending in a New-Keynesian model with search and matching frictions featuring endogenous growth through learning-by-doing and skill loss from long-term unemployment. We show that medium-run and long-run output and unemployment multipliers are much larger...

International diffusion of advanced environment and energy-related technologies has received much attention in recent environmental economics studies. As a much needed complement to the "black box" complex numerical modelling, this paper contributes to developing a simple, intuitive analytical...
