This study aims to examine the performance of Indonesian employee pension funds based on technical and scale efficiencies. Our sample is 40 Indonesian pension funds in the 2011-2017 period, resulting in 280 firm-year observations. Data Envelopment Analysis (DEA) is used to measure pension funds’ efficiency levels. The results show Indonesian employee pension funds generally cannot operate efficiently. However, based on their size, large pension funds exhibit better technical efficiency levels than small pension funds. Conversely, small pension funds perform better in scale efficiency. Other findings document that, from the ownership perspective, state-owned enterprise (SOE) pension funds exhibit better technical efficiency levels than non-SOE ones. This study also proposes the managers of Indonesian employee pension need to improve their pension fund performance by reducing operational and investment costs and engaging in greater investment diversification.
