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...

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...

Understanding the factors that may impact how well universities are transforminga set of inputs into research outputs is of great interest for university andpublic authorities. The goal of this paper is on the one hand to measure the researchefficiencies of US universities and on the other hand...

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 e¢ cient but a¤ected by them. Some simulations are...
