This paper uses a micro-founded DSGE model to compare second-best optimal environmental policy and the resulting allocation to first-best allocation. The focus is on the source and size of uncertainty, and how this affects optimal choices and the inferiority of second best vis-à-vis first best.

Using a heterogeneous agent model allowing for different degrees of complementarity between capital, skilled and unskilled labour, this paper evaluates supply-side reforms consistent with lower public debt-to-GDP in the long-run. We find that, relative to the other tax reforms, capital tax cuts...

Robust decision making implies welfare costs or robustness premia when the approximating model is the true data generating process. To examine the importance of these premia at the aggregate level we employ a simple two-sector dynamic general equilibrium model with human capital and introduce an...

In this paper we study the quantitative macroeconomic effects of public education spending in USA for the post-war period. Using comparable measures of human and physical capital, from Jorgenson and Fraumeni (1989, 1992a,b), we calibrate a standard dynamic general equilibrium model where human...

This paper uses a micro-founded DSGE model to compare second-best optimal environmental policy, and the resulting Ramsey allocation, to first-best allocation. The focus is on the source and size of uncertainty, and how this affects optimal choices and the comparison between second- and...

We welfare rank different types of second-best environmental policy. The focus is on the roles of uncertainty and public finance. The setup is the basic stochastic neoclassical growth model augmented with the assumptions that pollution occurs as a by-product of output produced and environmental...
