This paper studies the persistence of the effects that terrorism exert on municipality size. With this aim, we propose to implement new difference-in-differences techniques that control for heterogeneous effects across units and time. Using data of Colombia covering the period 1985-2020, we...

This paper incorporates time-dependence into a regional knowledge production function framework. Within this setup, the long-run dynamic behaviour of R&D and knowledge has been analysed in four European countries - France, Germany, Italy and Spain - using unit root tests and cointegration...

This paper introduces technological interdependence à la Ertur and Koch (Growth, technological interdependence and spatial externalities: Theory and evidence. Journal of Applied Econometrics 2007; 22: 1023-1062) into the theoretical framework of Gennaioli et al. (Human capital and regional...

This paper studies the link between knowledge, innovation and growth in European regions using nonparametric methods. Our findings suggest that knowledge inputs and the share of innovative firms have a heterogeneous and nonlinear relationship with growth. This evidence has been exploited to...

This paper studies the persistence of the effects of terrorist attacks on the urban structure at regional level. With this aim, a dynamic differences-in-differences approach is applied to all the municipalities of the Basque Country and Navarre autonomous communities in Spain during 1986-2014....

This paper analyses the possible presence of Granger causality between military spending and unemployment rates in the EU15 countries. The panel bootstrap test applied allows us to control for both the presence of cross-country heterogeneity and cross-sectional dependence. Considering two...

This paper introduces model uncertainty into the empirical study of the determinants of terrorism at country level. This is done by adopting a Bayesian model averaging approach and accounting for the over-dispersed count data nature of terrorist attacks. Both a broad measure of terrorism and...

Grounded on the concept of cointegration, this paper develops a novel test of time series convergence between pairs of unit root processes. The test (i) does not require the estimation of the cointegration coeffcient, (ii) is robust to general forms of weak dependence in the transitory...
