For reason of empirical tractability, analysis of cointegrated economic time series is often developed in a partial setting, in which a subset of variables is explicitly modeled conditional on the rest. This approach yields valid inference only if the conditioning variables are weakly exogenous...

This paper offers an empirical evaluation of the output contribution of infrastructure. Drawing from a large data set on infrastructure stocks covering 88 countries and spanning the years 1960-2000, and using a panel time-series approach, the paper estimates a long-run aggregate production...

The sovereign debt crisis in the euro area has raised interest in early warning indicators, aimed at signalling the build-up of fiscal stress in advance and helping prevent crises by means of a timely counteraction of fiscal and macroeconomic policies. This paper presents possible improvements...

This paper studies the public sector wage gap in Spain by gender, skill level and type of contract, using recent administrative data from tax records. We estimate wage distributions in the presence of covariates separately for men and women in the public and in the private sectors, and we take...

Model uncertainty remains a challenge to applied researchers in economics. When many competing models are available for estimation and without enough guidance from theory, model averaging represents an alternative to model selection. Despite model averaging approaches have been present in...

The containment of health care expenditure is one of the major challenges facing public policymakers in the developed countries. This paper provides evidence of significant differences in the cross-country level of efficiency of health care expenditure, meaning that potential cost savings for...

This paper tests the opportunity-cost theory using a panel of Spanish firms during the period 1991-2010. Under this theory, productivity-enhancing activities, such as R&D investment, should increase during downturns because of the fall in their relative cost – in terms of forgone output –....

This paper considers panel growth regressions in the presence of model uncertainty and reverse causality concerns. For this purpose, my econometric framework combines Bayesian Model Averaging with a suitable likelihood function for dynamic panel models with weakly exogenous regressors and fixed...

Model uncertainty hampers consensus on the main determinants of corporate default. We employ Bayesian model averaging (BMA) techniques in order to shed light on this issue. Empirical findings suggest that the most robust determinants of corporate default are firm-specific variables such as the...

What are the output responses to fiscal policy? Despite important advances reported in the literature, quantifying the size of the fiscal multiplier remains a challenge. Indeed, the quest to estimate a unique fiscal multiplier is probably an ill-posed one. The magnitude of the multiplier may...
