In this paper we study the impact of ICT capital in developed countries during 1980-1995. We use Solow’s growth accounting methodology synthesized with statistical testing about equality of distributions and multimodality of distributions. We test for significance of a contribution from each...

In this note we investigate the power of significance test for dummy-variables in the context of Simar and Wilson (2003) two-stage efficiency analysis model.

In this paper we extend the work of Färe and Zelenyuk (2003) to find a theoretically justified method of aggregating Malmquist Productivity Indexes over individual decision making units (firms, countries, etc.) into a group Malmquist Productivity Index. We also consider the aggregation of...
