We investigate the possibility that in the foreign exchange market an uninformed speculator finds it convenient to trade on noise in order to gain an infromational advantage she can exploit in future. In a two-period model, we analyze the trade-off she faces between the cost of the...

We propose a critical review of recent developments in exchange rate economics which have offered a novel approach to exchange rate determination. This new strand of research, the market microstructure approach to exchange rates, is motivated by some very stark empirical evidence, relating...

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 this paper we characterize the preferences of a pessimistic social planner concerned with the potential costs of extreme, low-probability climate events. This pessimistic attitude is represented by a recursive optimization criterion à la Hansen and Sargent (1995) that introduces...

Countries can repeatedly and opportunistically renegotiate the terms of agreements to which they can only complicitly assent. Therefore, when attempting to coordinate exchange rate policies, they continuously play partnership games. We develop a reduced form model of exchange rate management...

We propose a simple structural model of exchange rate determination which draws from the analytical framework recently proposed by Bacchetta and van Wincoop (2003) and allows us to disentangle the liquidity and information effects of order flow on exchange rates. We estimate this model employing...
