Many monetary and fiscal policy decision makers and economists hold the view that exchange rates are volatile even though nominal exchange rates vary less than many other financial market prices and yields. This paper seeks an explanation for this puzzle by contrasting exchange rate dynamics in...

This paper uses a stochastic growth model with consumption, saving, portfolio choice between real capital and government bonds and money holding as a cash-in-advance constraint. It shows that money supply changes due to government expenditure changes or open market operations are never...

We consider a simple general equilibrium model for the determination of asset prices together with full equilibria in the commodity and money markets. In this way portfolio aspects are introduced into a dynamic macro model which has many features from growth theory. Money holdings are modelled...

The authors consider a dynamic stochastic general equilibrium model with a representative consumer-investor and two producing firms. All the assets are real investments of capital into productive processes. Government expenditures, taxes, and money financing are explicitly incorporated. The...

In this paper we develop a stochastic monetary growth model with exogenous productivity shocks to consider the effects of changes in the financing structure of government deficits on the key variables of the economy. We study how the presence of supply-side uncertainty affects the equilibrium of...

We develop a continuous-time stochastic growth model with recursive preferences, money and public debt. In equilibrium growth and inflation follow geometric Brownian motions, with parameters determined by solving a system of nonlinear equations. Permanent changes in government expenditures and...

Central securities depositories (CSDs) have opened mutual links, but most of them are seldom used. Why are idle links established? By allowing a foreign CSD to offer services through the link the domestic CSD invites competition. The domestic CSD can determine the cost efficiency of the rival by...

Recently, banking literature has had a quest for appropriate pricing of bank loans under the new Basel II rules and has been in pursuit of possible outcomes for undertaking such credit risk. In this paper, we propose a simplified formula to price bank’s corporate loans, aiming at making bank...

We study the effects of model uncertainty in a simple New-Keynesian model using robust control techniques. Due to the simple model structure, we are able to find closed-form solutions for the robust control problem, analysing both instrument rules and targeting rules under different timing...

We study the long standing issue of whether markets can supply banks with sufficient liquidity or whether markets should be complemented with a lender of last resort (LOLR). For this purpose, we develop an extended version of the recent model of Holmström and Tirole (1998) on the supply of...
