The empirical relationship between money and output is one of the most studied issues in macroeconomics, and a large literature has examined the causal links between monetary variables and output. One puzzle from this literature is that the results of causality tests appear to be sensitive with...

It has been recognized that the optimal strategy of a government is generally time-inconsistent: optimality requires that the government take into account expectations effects in the formulation of its policy and to ignore these effects when applying the policy. In order to analyse the problem,...

This paper provides a general review of recent developments in the application of control theory to macroeconomic policy design. It starts by highlighting the crucial difference between the engineering and economic control problem, in that the latter, unlike the former, is concerned with the...

A model of profits switches between four regimes with fixed probabilities; the rationally expected profits stream implies the stock market value. This efficient market model is not rejected by UK post-war time-series behaviour of either profits or the FTSE index.

We examine several continuous-time term-structure models, in which the short rate is subject to discrete shifts. Our empirical analysis suggests that inquiring which parameters of the short-term interest rate equation are allowed to switch is crucial, as failing to do so may result in switching...

This paper is about the properties of Markov switching rational expectations (MSRE) models. We present a simple monetary policy model that switches between two regimes with known transition probabilities. The first regime, treated in isolation, has a unique determinate rational expectations...

We study the relationship between the term structure of interest rates and fiscal policy by considering the Italian case. Empirical analysis has been so far rather inconclusive on this important topic. We abscribe such evidence to three problems: identification, regime-switching and maturity...

When the 1987 general elections brought a durable government to Portugal, the national environment was still inflationary. Nevertheless, thanks to the efforts of successive ministers of finance/central bank governor pairs, the criteria for Economic and Monetary Union (EMU) were met and the...

We investigate the dynamic relationship between the US dollar exchange rate and its fundamentals across different exchange rate regimes using data going back to the late 1800s or early 1900s for six industrialized countries. For these countries there is evidence of a long-run relation between...

In this paper the surprising conclusion of Smith and Smith (1990) that the prospect of Britain's return to gold in 1925 had the effect of weakening sterling is subjected to critical analysis. It is shown that this conclusion is reversed when the trend in the UK money stock prior to joining the...
