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...

The impact of human and public capital on growth is a major issue in economic theory and in policy evaluation. Using a cointegrated VAR, we estimate a Cobb-Douglas production function for Portugal with public and human capital. Return rates are then computed with and without dynamic feedbacks....

Considering the case of Portugal over the period 1995-2000, this paper analyses whether the location of market services is explained by the geographical proximity of the industrial sectors that use these services as intermediate inputs. A rather detailed level of regional disaggregation is used,...

There is scant evidence on the determinant factors of structural similarity between geographical spaces; moreover, it has been produced considering only the national level. The present study provides evidence on this topic at the regional level, based on the analysis of 275 Portuguese counties....

We use a threshold VAR analysis to study whether the effects of fiscal policy on economic activity differ depending on financial market conditions. In particular, we investigate the possibility of a non-linear propagation of fiscal developments according to different financial market stress...

I use a panel of semi-annual vintages of growth and fiscal forecasts of the European Commission, covering the period 1998:II-2008:II, to assess its effects on 10-year government yields for 14 EU countries. Results show that yields increase with better growth forecasts, and with decreases in...

We estimate changes in fiscal policy regimes in Portugal with a Markov Switching regression of fiscal policy rules for the period 1978-2007, using a new dataset of fiscal quarterly series. We find evidence of a deficit bias, while repeated reversals of taxes making the budget procyclical....

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...

This study assesses the short and long-run behaviour of long-term sovereign bond yields in OECD countries, for the period 1973-2008. We employ a dynamic panel approach to reflect financial and economic integration, and to increase the performance and accuracy of the tests. Given the existence of...
