We develop a novel approach to build checks of parametric regression models when many regressors are present, based on a class of sufficiently rich semiparametric alternatives, namely single-index models. We propose an omnibus test based on the kernel method that performs against a sequence of...

In empirical research, one commonly aims to obtain evidence in favor of restrictions on parameters, appearing as an economic hypothesis, a consequence of economic theory, or an econometric modeling assumption. I propose a new theoretical framework based on the Kullback–Leibler information to...

To study the influence of a bandwidth parameter in inference with conditional moments, we propose a new class of estimators and establish an asymptotic representation of our estimator as a process indexed by a bandwidth, which can vary within a wide range including bandwidths independent of the...

We consider conditional moment models under semi-strong identification. Identification strength is directly defined through the conditional moments that flatten as the sample size increases. Our new minimum distance estimator is consistent, asymptotically normal, robust to semi-strong...

The surge of government debt during the post-global financial crisis and the ongoing euro zone sovereign debt crisis has begun raising concerns whether government debt levels have hit the tipping points. This study offers to contribute in the following ways: First, we find out whether the...

The dynamics of government debt and economic growth, once a subject of interest mostly to very few macroeconomists is suddenly of immense attention for many researchers in the backdrop of Euro zone sovereign debt crisis and Reinhart & Rogoff’s related research. This study investigates the...
