In a recent paper published in Public Choice, Konstantinos Angelopoulos, Apostolis Philippopoulos and Efthymios Tsionas provide a welcome addition to the empirical growth literature by enlarging the traditional focus on fiscal size to introduce measures of public sector efficiency. Two such measures of public sector efficiency are used.
The first one follows the “output-to-input” (or, as it might be more appropriately denominated, outcome-to-input) approach used by Afonso, Schuknecht, and Tanzi in two famous papers ("Public sector efficiency: an international comparison," Public Choice Volume 123, Number 3-4, June 2005; and "Public Sector Efficiency: evidence from new EU members states and emerging markets," ECB Working Papers number 581, January 2006) governements’ socio-economic outcomes are related to resources used, proxied by public sector spending, for major functions—limited by data availability, in the article’s case, to four basic roles of administration, education, infrastructures, and economic stabilization. The sample consists of 64 developed and non developed countries during four five-year periods between 1980 and 2000.
The second measure of government efficiency to which the model is applied is obtained by applying a stochastic production frontier approach as discussed in Lovell and Kumbhakar’s book (2000). The sample consists here of yearly data between 1995 and 2000 for 52 countries.
