This paper develops linear quadratic robust control theory for a class of spatially invariant distributed control systems that appear in areas of economics such as New Economic Geography, management of ecological systems, optimal harvesting of spatially mobile species, and the like. Since this...

The precautionary principle (PP) applied to environmental policy stipulates that, in the presence of physical uncertainty, society must take robust preventive action to guard against worst-case outcomes. It follows that the higher the degree of uncertainty, the more aggressive this preventive...

This paper studies the design of optimal time-consistent monetary policy in an economy where the planner trusts its own model, while a representative household uses a set of alternative probability distributions governing the evolution of the exogenous state of the economy. In such environments,...

I entertain a generalization of the standard Bolzmann-Gibbs-Shannon measure of entropy in multiplier preferences of model uncertainty. Using this measure, I derive a generalized exponential certainty equivalent, which nests the exponential certainty equivalent of the standard Hansen-Sargent...

This paper extends Svensson and Woodford's (2003) partial information framework by allowing the private agents to achieve robustness against incomplete information about the structure of the economy by distorting their expectations in a particular direction.It shows how a linear rational...

The design of optimal environmental policy inherits model uncertainty. We investigate the consequences in a simple linear model, where the aim of the policymaker is to stabilize the atmospheric content of carbon. We study how decision-makers' concerns about robustness alters policy using the...

Abstract: The robust permanent income model discussed in a number of works, see e.g. Hansen et al. (1999, 2002), is reformulated as a linear quadratic tracking problem with a time-varying intercept following a ‘Return to Normality’ model. The results in Tucci (2005), which...

This paper builds upon the work by Tucci and Kendrick (2001) in which the authors develop a quadratic form version of the robust permanent income and pricing model described in Hansen, Sargent and Tallerini (1999). Then using the parameter values given on p. 18 of the HST paper they compute the...
