This paper explores some implications of the use of national currencies as international reserves. First, a closed economy overlapping-generations model is developed to derive time-consistent tax and inflation policies for a government that is financing a given stream of expenditures. Second,...

The distinctiof between predetermined and non-predetermined variables is a crucial one in rational expectations models. I consider and reject two definitions, one proposed by Blanchard and Kahn and one by Chow. Both definitions lead to possible misc1assifications. Instead I propose the following...

The paper presents a general solution method for rational expectations models that can be represented by systems of. deterministic first order linear differential equations with constant coefficients. It is the continuous time adaptation of the method of Blanchard and Kahn. To obtain a unique...

Implementing a 'gradualist' policy of monetary contraction, in an open economy with a freely floating exchange rate but with nominal inertia in domestic labor costs, can lead to prompt and substantial changes in the nominal and real exchange rate. One of the virtues claimed for such exchange...

The paper analyzes the modalities and consequences of a breakdown of cooperation between the monetary authorities of inflation-prone Periphery Countries that use an exchange rate peg as an anti- inflationary device, when the Center is hit by an aggregate demand shock. Cooperation in the...

The paper reviews recent developments in macroeconomic theory and their implications for econometric modelling and for policy design. The following issues are addressed. 1) The theoretical and practical problems of modelling sequence economies. 2) Problems of evaluating the role of money given...

The paper considers the response of a small, open dependent economy to a variety of fiscal and financial shocks as well as the influence of alternative budget balancing rules on the response of the system to such external shocks as a change in the world interest rate. The approach allows for...

This paper aims to provide a stochastic, rational expectations extension of Tobin's "Money and Income; Post Hoc Ergo Proper Hoc?". It is well-known that money may Granger-cause real variables even though the joint density function of the real variables is invariant under changes in the...

The paper demonstrates that the concepts of dynamic controllability are useful for the theory of economic policy by establishing four propositions. First dynamic controllability is a central concept in stabilization policy. Second, the ability to achieve a target state, even if it cannot be...

This paper considers the effects of fiscal and financial policy on economic growth in open and closed economies, when human capital formation by young households is constrained by the illiquidity of human wealth. Both endogenous and exogenous growth versions of the basic OLG model are analyzed....
