This notes shows how intertemporal and cross-section welfare are related in a general class of stochastic continuous time models. In the steady state intertemporal welfare is shown to be proportional to cross-sectional income. This result holds for economies where each agent maximizes his own...

The energy transition from fossil fuels to alternative energy sources has important consequences for technological change and resource extraction. We examine these consequences by incorporating a non-renewable resource and an alternative energy source in a market economy model of endogenous...

We argue that expectations about future energy use affect the transition from fossil fuels to renewable substitutes, because of an interaction between innovation and resource scarcity. The paper presents a model of directed technical change to study this interaction. We find that resource-saving...
