This paper surveys the link between imperfect competition and the e¤ects of fiscal policy on output, employment and welfare. We examine static and dynamic models, with and without entry under a variety of assumptions using a common analytical framework. We find that in general there is a robust...

We investigate the existence of Granger-causality between current account and government budget balances over the period 1970-2007, for different EU and OECD country groupings. We use a panel-data approach based on SUR systems and Wald tests with country specific bootstrap critical values. Our...

We assess the sustainability of public finances in the EU15 over the period 1970-2006 using stationarity and cointegration analysis. Specifically, we use panel unit root tests of the first and second generation allowing in some cases for structural breaks. We also apply modern panel...

This note analyses a simple imperfectly competitive general equilibrium model where the entry mechanism generates an endogenous markup. In this second-best world fiscal policy is more effective than in Walrasian or in fixed-markup monopolistic competition models, as it produces efficiency gains...

We apply recent panel cointegration methods to a structural equation between government expenditure and revenue. Allowing for multiple endogenous breaks and after computing appropriate bootstrap critical values, we conclude for fiscal sustainability in the overall EU15 panel.

In a recent article Chen et al. (2005) analyse the role of government expenditure in an imperfectly competitive static model, introducing a government-expenditure externality through the production function. Our purpose in the present paper is to argue that the claim from the authors that their...

We use a 3-step analysis to assess the sustainability of public finances in the EU27. Firstly, we perform the SURADF specific panel unit root test to investigate the meanreverting behaviour of general government expenditure and revenue ratios. Secondly, we apply the bootstrap panel cointegration...

We assess the cointegration relationship between current account and budget balances, and effective real exchange rates, using recent bootstrap panel cointegration techniques and SUR methods. We investigate the magnitude of the relationship between the two imbalances for each country for the...

We study sovereign bond yields in OECD countries with a dynamic panel by checking for cross-section dependence; assessing panel cointegration; and estimating panel errorcorrection models. The results show that markets consider budgetary and external imbalances and inflation as relevant...
