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 empirical importance of our theoretical concerns is then examined with the aid of two hypotheses. According to the first...

In this paper we examine the importance of imperfect competition in product and labour markets in determining the long-run welfare effects of tax reforms assuming agent heterogeneity in capital holdings. Each of these market failures, independently, results in welfare losses for at least a...

In this paper we construct a stylised general equilibrium macromodel to show that demand led expansions may have unexpected effects when market imperfections lead to changes in labour productivity. We find some empirical support, from a number of European countries, for the main predictions of...

This paper analyzes whether differences in institutional structures on capital markets contribute to explaining why some OECD-countries, in particular the Anglo-Saxon countries, have been much more successful over the last two decades in producing employment growth and in reducing unemployment...

We argue that, under certain conditions, firms consider exports as a substitute for domestic demand. Our econometric model for six euro area countries suggests domestic demand and capacity constraints as additional variables for export equations. We apply the exponential and logistic variant of...

This paper undertakes a normative investigation of the quantitative properties of optimal tax smoothing in a business cycle model with state contingent debt, capital-skill complementarity, endogenous skill formation and stochastic shocks to public consumption as well as total factor and capital...

A persistent criticism of general equilibrium models of monetary policy which incorporate nominal inertia in the form of the New Keynesian Phillips Curve (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...

In this paper we study the link between elections, fiscal policy and aggregate fluctuations. The set-up is a stylized dynamic stochastic general equilibrium model incorporating both technology and political re-election shocks. The later are incorporated via a two-party model with elections. The...

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...

This paper develops an incomplete markets model with state dependent (Markovian) stochastic earnings processes and ex ante skill heterogeneity corresponding to being university educated or not. Using the Wealth and Assets Survey for Great Britain, we find that the university educated group has...
