In regression analysis, classical estimations may be excessively influenced by a few atypical observations. We propose a Hausman-type test to balance robustness and efficiency and to check whether a robust method should be implemented. An economic application is presented.

In this paper, we follow the same logic as in Hausman (1978) to create a testing procedure that checks for the presence of outliers by comparing a regression estimator that is robust to outliers (S-estimator), with another that is more efficient but affected by them. Some simulations are...

From the literature on decentralization, it appears that the fiscal vertical imbalance (i.e. the dependence of sub-national governments on national government revenues to support their expenditures) is somehow inherent to multi-level governments. Using a stylized model we show that this leads to...

The aim of this paper is to test whether electoral systems and human development are linked. Using high-quality data and very simple panel data econometric techniques, we show that electoral systems play a critical role in explaining the difference in the levels of human development between...

This paper analyses whether the current provision of air services in Europe is impacted by high-speed rail (HSR). An ex-post analysis is carried out covering a large sample of 161 routes EU-wide using transnational data. We use censored regressions with special attention paid to the presence of...

Contrasting with extant research centred on the organizational challenges of sourcing services in culturally distant countries, we show that cultural differences between home and host countries do not prevent firms from achieving their cost savings targets. Instead, the effect is positive, both...
