We consider VAR models for variables exhibiting cointegration and comon cyclical features. While the presence of cointegration reduces the rank of the long-run multiplier matrix, other types of common features lead to rank reduction of the short-run dynamics. We distinguish between strong and...

A persistent criticism of general equilibrium models of monetary policy which incorporate nominal inertia in the form of the New Keynesian Phillips Curce (NKPC) is that they fail to capture the extent of inflation inertia in the data. In this paper we derive a general equilibrium model based on...

This paper searches for a general equilibrium model of optimal growth and endogenous fiscal policy with the aim of explaining the interaction between private agents and fiscal authorities in the U.S., West Germany, Japan and the U.K. over the period 1960-1996. Our search is conducted in the...

In this paper we use a model of vertical product differentiation to cast doubt on the general validity of the import demand function as specified in macroeconomic models. The empiricai importance of our theoretical concerns is then examined with the aid of two hypotheses. According to the first...

In this paper we develop a multi-sector model of firms' pricing behaviour under imperfect competition. We allow for the fact that some goods sold will be for final consumption, while others will be used as intermediate goods in further production. We assume that price setters are constrained by...
