Nonrenewable resource scarcity has been a traditional concern when designing optimal growth models. Technological change has played an important role in those models, since its presence is assumed to mitigate the depletion effect on extraction paths over time. We formalize the general problem of...

Models of economic growth are typically based on the use of one or more stocks of productive assets to create goods for utility-generating consumption. The roles played by man-made capital, natural capital and human capital have been explored, often separately, in the literature, and more...

We use an endogenous growth model to contrast the socially optimal allocation of human capital with the decentralized solution, in a context where workers make the choices that determine social capital accumulation. As social capital is expected to increase productivity but is not traded in...

We derive a model of endogenous growth with physical capital, human capital and technological progress through quality-ladders. We introduce welfare-decreasing pollution in the model, which can be reduced through the development of cleaner technologies. From the quantitative analysis of the...
