This paper shows that, by disentangling the degree of monopolistic distortion from the elasticity of substitution between domestic and im-ported goods, we can obtain a negative response of the trade balance to positive monetary shocks, without introducing capital accumula-tion. This result could...

This paper studies the applicability of the Marshall-Lerner condition to the “basic” Obstfeld and Rogoff (1995) model. It shows that the Marshall-Lerner condition does apply to this class of models with homothetic preferences when product differentiation across countries is imposed. This...

Some economic models like the cash-in-advance model of money or overlapping generations model have the property that the dynamics are ill-defined going forward in time, but well-defined going backward in time. In such instances, what does it mean for an ill-defined dynamical system to be...

Some economic models like the cash-in-advance model of money have the property that the dynamics are ill-defined going forward in time, but well-defined going backward in time. In this paper, we apply the theory of inverse limits to characterize topologically all possible solutions to a dynamic...

Some economic models like the cash-in-advance model of money have the property that the dynamical system characterizing equilibria is multi-valued going forward in time, but single-valued going backward in time, i.e., the model has backward dynamics. In this paper, we apply the theory of inverse...

In this paper, we provide a framework for calculating expected utility in models with chaotic equilibria and consequently a framework for ranking chaos. Suppose that a dynamic economic model’s equilibria correspond to orbits generated by a chaotic dynamical system f : X ! X where X is a...

The Taylor hypothesis is the conjecture that the 2007-2009 financial crisis and the 2008-present downturn have been caused by loose monetary policy during 2002-2006. According to the Taylor hypothesis the Fed deviated from well-know rules of monetary policy-making over this period, and this...

This paper investigates a new mechanism through which "liquidity effects" (i.e. a negative response of the nominal interest rate to monetary injections) can be introduced into dynamic stochastic general equilibrium (DSGE) models. As it turns out, this liquidity effect has been found difficult to...

"Active Intermediation in a Monetary Overlapping Generations Economy" ( ps,297K) ( pdf,600K ), (with M. Pingle), Economic Report No. 42, Iowa State University, April 1997. Final version appears in Macroeconomic Dynamics 2 (1998), pp. 183--212. Abstract: This study demonstrates that the reason...

This paper proposes a simple and unifying model to price the interest rate contingent claims in a complete market where trading can be made in continuous time. The underlying dynamics of the yield curve is modelled by a random string whose trajectory produces a random surface described by a...
