This paper measures environmental efficiency (EE) and environmental productivity (EP) and analyzes differences in these across countries. It explores the macro-economic factors that could explain these differences and whether these differences can be explained by income levels and by the degree...

This paper studies the productivity impact of heterogeneous capital inputs of selected EU-15 member countries and of the U.S. at the macroeconomic level. The stochastic possibility frontiers approach of Battese and Coelli (1992) applied here is used to identify neutralities or non-neutralities...

Korea imports all of its primary energy, which leads to high dependency and vulnerability related to its energy supply. Efficiency in the use of energy is a way to reduce dependency and emissions. This study provides empirical results of the stochastic production process in energy use. Special...

In recent years, literature has linked structural reforms with productivity growth. Considering Portugal’s recent comprehensive reform agenda, this topic acquires particular relevance. Using data for Portuguese firms for the period 2006-2014, this paper assesses the impact of structural...

The goal of this paper is to investigate the impact of technology investments on production efficiency in manufacturing companies and how different these relationships are for low-technology and high-technology companies. The empirical part was based on the analysis of 2,848 large, small and...

Technological upgradation and increasing capital intensity in organised manufacturing sector in India has been championed on grounds of improving productivity, efficiency, and competitiveness. In a developing economy this is a costly proposition due to capital scarcity, and the effect of...

This paper studies whether skilled migrants contribute to the host country's "productive efficiency" (Farrell, 1957) using input-output and immigration sectoral data for seven industries in twelve countries during the period 1999-2001. We find that skilled migrants contribute positively to a...
