ASSESSING PUBLIC SPENDING EFFICIENCY IN 20 OECD COUNTRIES

Being allocated a large share of a country?s GDP to the public spending, would rise the question of whether these resources are distributed and allocated in an efficient manner that leads the country to go through the growth enhancing economic path or not. This study is mainly going to follow Afonso, Schuknecht, and Tanzi (2005), aiming to look at the public expenditure of 20 OECD countries for the period 2009-2013, from the perspective of efficiency and assess if these developed countries are performing efficiently compared to each other. In order to evaluate the efficiency scores, Public Sector Performance (PSP) and Public Sector Efficiency (PSE) indicators were constructed and Data Envelopment Analysis was conducted. The results of these analyses show that the only country that performed on the efficiency frontier is Switzerland. The average input-oriented efficiency score is equal to 0.732. That is, on average countries could have reduced the level of pub-lic expenditure by 26.8% and still achieved the same level of public performance. The av-erage output-oriented efficiency score is 0.769 denoting that on average the sample coun-tries could have increased their performance by 23.1% by employing the same level of public expenditure.
