Comparing school ownership performance using a pseudo-panel database: A Malmquist-type index approach

Abstract

In this paper, we propose a different way of using the Malmquist index that allows us to further an- alyze the relative performance divergences between two groups of decision-making units (DMUs) over time when only a pseudo-panel database is available. To do this, we extend the Camanho and Dyson (2006) one-period Malmquist-type index (CDMI) for a pseudo-panel database with a new pseudo-panel Malmquist index (PPMI). To illustrate the methodology, we apply it to examine how the performance gap between public and private government-dependent secondary schools in the Basque Country (Spain) performed across three PISA waves (20 06, 20 09 and 2012). The results suggest that performance is per- sistently and significantly higher for private government-dependent schools than for public schools
