We consider a neo-classical model of optimal economic growth with c.r.r.a. utility in which the traditional deterministic trends representing population growth, technological progress, depreciation and impatience are replaced by Brownian motions with drift. When transformed to 'intensive' units,...

The paper derives the optimal carbon tax in closed-form from an integrated assessment of climate change. The formula shows how carbon, temperature, and economic dynamics quantify the optimal mitigation effort. The model’s descriptive power is comparable to numeric models used in policy...

Necessary and sufficient conditions are derived for optimal saving in a stochastic neo-classical one-good world with discrete time. The usual technique of dynamic programming is replaced by classical variational and concavity arguments, modified to take account of conditions of measurability...

This paper reviews the application of social welfare functions (SWFs) in welfare-maximizing climate policy analysis. We identify several methodological inconsistencies, analyze their policy implications, discuss the theoretical questions raised by them, and provide recommendations for future...

This paper develops a dynamic general-equilibrium model with production to examine the inter-relationships between the real and the financial sectors with and without credit market imperfections. Due to the moral hazard problem, borrowers may take the money and run while lenders may ration...
