This paper explains how, in the context of incomplete coordination among all countries, unilateral policies that might at first sight seem pro-green could actually turn out to harm the global environment. The free-riding motives and the difficulty of reaching an effective international...

This paper develops sufficient conditions under which the Weak Green Paradox may (and may not) hold in terms of subsidies for biofuel production such that the supply-side responses by fossil fuel producers may more than offset the substitution to biofuels. Analytical results are derived and...

When analyzing potential ways to counter climate change, standard models of green growth abstract from investment in substitutability between “clean” and “dirty” energy inputs. Instead, they rely on the assumption that efficiency with respect to fossil fuels can be increased perpetually....

We document that global resource extraction has strongly increased with economic growth, while prices have exhibited stable trends for almost all major non-renewable resources from 1700 to 2018. Why have resources not become scarcer as suggested by standard economic theory? We develop a theory...

This article considers an economy whose production function takes both renewable and non-renewable resources as inputs. We extend the current literature by allowing for exogenous technical change in the elasticity of substitution between these two types of resources. In addition, we study the...

We add an extractive sector to an endogenous growth model of expanding varieties and directed technological change. Extractive firms reduce the stock of non-renewable resources through extraction, but also increase the stock through R&D investment in extraction technology. Our model replicates...

We analyze a dynamic game between a buyer and a seller of an exhaustible resource. The seller chooses resource supply; the buyer can pay a fixed cost to invent a perfect substitute for the resource at any time. In closed-loop equilibrium, the buyer adopts the substitute when the resource is...
