We compare the performance of perturbation, projection, and stochastic simulation algorithms for solving the multi-country RBC model described in Den Haan et al. (this issue). The main challenge of solving this model comes from its large number of continuous-valued state variables, ranging...

I propose a Galerkin projection method for solving dynamic economic models with many state variables. This method employs non-product monomial integration formulas for the computation of weighted residuals, and its computational cost therefore increases only polynomially in the model's...

This paper studies optimal fiscal and monetary policies in an economy exposed to large adverse shocks (rare disasters). We contrast optimal policies under commitment and discretion and identify several striking differences between these institutional environments. A government that can commit to...

We study the sustainability of public debt in a closed production economy where a benevolent government chooses scal policies, including haircuts on its outstanding debt, in a discretionary manner. Government bonds are held by domestic agents to smooth consumption over time and because they...

We study optimal time-consistent fiscal policy in a neoclassical economy with endogenous government spending, physical capital and public debt. We show that a dynamic complementarity between the households’ consumption-savings decision and the government’s policy decision gives rise to a...

We describe a simple mechanism that generates inflation persistence in a standard sticky-price model of optimal fiscal and monetary policy. Key to this mechanism is that policies are implemented under discretion. The government's discretionary incentive to erode the real value of nominal public...

We use low-order projection methods to compute numerical solutions of the basic neoclassical stochastic growth model. We assess the quality of the obtained solutions, and compare them to numerical approximations derived with first and second-order perturbation techniques. We show that projection...
