We extend Svensson's (Svensson, 1997) model of optimal monetary policy to the case in which the monetary authorities are pessimistic. With respect to his formulation we show that: i) the inflation forecast is no longer an explicit intermediate target; ii) the monetary authorities move their...

We discuss how Whittle's (Whittle, 1990) approach to risk-sensitive optimal control problems can be applied in economics and finance. We show how his analysis of the class of Linear Exponential Quadratic Gaussian problems can be extended to accommodate time-discounting, while preserving its...

In an asset market with explicit trading rules we characterize the trading activity of an ambiguity-averse insider who faces Knightian uncertain over other market participants' beliefs and implements a robust trading strategy. Such insider employs a max-min choice mechanism, so that in any round...

We propose a general framework for the analysis of dynamic optimization with risk- averse agents, extending Whittle's (Whittle, 1990) formulation of risk-sensitive optimal control problems to accommodate time-discounting. We show how, within a Markovian set-up, optimal risk-averse behavior is...
