DPIN Version 1.0 is a fast userâ€friendly program for computing and Decomposing Productivity Index Numbers. The program uses the conceptual framework developed by O'Donnell (2008) and the data envelopment analysis (DEA) programs developed by O'Donnell (2009). This paper describes the...

The product test asks the product of a quantity index number and a price index number to equal the corresponding value change. The literature treats the product test as being so important that it is used to identify acceptable index number pairs, and to construct implicit index numbers when an...

A primal index of productivity change is introduced which decomposes exactly in three components: technical change, technical efficiency change and average scale economies (radial scale change). The proposed index is invariant to movement along indifference surfaces and it collapses to the...

This paper presents productivity measurement results for hospital services using panel data for Ontario hospitals between 2003 and 2006. The study uses the Malmquist Productivity index (MPI) obtained through the application of Data Envelopment Analysis (DEA) which is decomposed into efficiency...

Profitability at a period of time is defined as the value of outputs produced by a production unit divided by the corresponding cost. Using some earlier work by O?Donnell, the paper provides a decomposition of profitability growth over two periods into various explanatory factors. The...

One of the main characteristics of the technological capabilities of countries has always been their uneven distribution across the countries. This paper explores the dynamic of technological capabilities for a sample of 42 countries over the period 1995-2007 introducing some methodological...

In this paper it is shown that a well known procedure (GEKS) of transitivizing a bilateral system of productivity comparisons is implicitly a way of imposing a homothetic structure onto the data. The main implication of this result is that deviations between the bilateral and the multilateral...

Users of data envelopment analysis (DEA) often presume efficiency estimates to be robust. While traditional DEA has been exposed to various sensitivity studies, network DEA (NDEA) has so far escaped similar scrutiny. Thus, there is a need to investigate the sensitivity of NDEA, further...

In the wake of the recent global financial crisis central banks and regulators are concerned about redirection of bailout funds into dividends. Yet, we do not know much about the extent banks follow dividend policies and funding decisions optimal to generating shareholders? wealth because banks...
