• Optimization in a Simulation Setting: Use of Function Approximation in Debt Strategy Analysis

  Staff Working Paper 2007-13 David Bolder, Tiago Rubin

  The stochastic simulation model suggested by Bolder (2003) for the analysis of the federal government's debt-management strategy provides a wide variety of useful information. It does not, however, assist in determining an optimal debt-management strategy for the government in its current form.

• Time-Consistent Control in Non-Linear Models

  Staff Working Paper 2007-3 Steve Ambler, Florian Pelgrin

  We show how to use optimal control theory to derive optimal time-consistent Markov-perfect government policies in nonlinear dynamic general equilibrium models, extending the result of Cohen and Michel (1988) for models with quadratic objective functions and linear dynamics. We replace private agents' costates by flexible functions of current states in the government's maximization problem.
