This paper develops a slack-based decomposition of profit efficiency based on a direc- tional distance function. It complements Cooper, Pastor, Aparicio and Borras (2011).

This paper analyses productivity growth in 16 of Taiwan's manufacturing industries during the period 1978-1992. The non-parametric Data Envelopment Analysis approach is used to compute Malmquist productivity indexes. These are decomposed into efficiency change and technical change. The latter is...

This paper addresses aspects of New Zealand's economic performance by first analysing the country's relative international position against a comparative group of five OECD countries. Cointegration test results fail to confirm prima facie evidence that New Zealand's per capita output is on a...

The last two decades have witnessed a revival in interest in the measurement of productive efficiency pioneered by (1957) and (1951). 1978 was a watershed year in this revival with the christening of DEA by (1978) and the critique of Farrell technical efficiency in terms of axiomatic production...

This paper proposes a trade restrictiveness indicator that explicitly incorporates environmental externalities. The index employs directional distance functions and use indicators (i.e. differences rather than ratios) modified to account for and evaluate efficiency changes in the face of...
