Noting that many economic variables display occasional shifts in their second order moments, we investigate the performance of homogenous panel unit root tests in the presence of permanent volatility shifts. It is shown that in this case, panel unit root tests derived under time invariant...

We introduce a new, factor based bootstrap approach which is robust under heteroskedastic error terms for inference in functional coefficient models. Modeling the functional coefficient parametrically, the bootstrap approximation of an F statistic is shown to hold asymptotically. In simulation...

Rational politicians are interested in judicial independence (JI) in order to make their promises credible. But if politicians preferences deviate from the dicta of the judiciary, they also have incentives to renege on judicial independence. These two conflicting aspects are measured by two...

It is argued that an independent judiciary is a necessary condition for both individual liberty and economic prosperity. After having surveyed the literature dealing with how to arrange for an independent judiciary, the authors derive some additional policy implications by drawing on two...

Over 10 years ago, Feld and Voigt (2003) introduced the first indicator for objectively meas-uring the actual independence of the judiciary and demonstrated its utility in a large cross-section of countries. The indicator has been widely used, but also criticized. This paper pre-sents more...

The paper contributes to the growing global VAR (GVAR) literature by showing how global and national shocks can be identified within a GVAR framework. The usefulness of the proposed approach is illustrated in an application to the analysis of the interactions between public debt and real output...

This paper presents a global model linking individual country vector error-correcting models in which the domestic variables are related to the country-specific variables as an approximate solution to a global common factor model. This global VAR is estimated for 26 countries, the euro area...
