ارزیابی دینامیک کارایی اصلاحات پس از عرضه توزیع برق در پاکستان

The power sector of Pakistan has undergone major reforms since 1994 with the objectives of increasing technical and financial performance of the sector. This study estimates and analyzes post reforms efficiency dynamics of electric distribution utilities from 2006 to 2013. Fixed effects stochastic frontier analysis results indicate that technical efficiency of utilities increased by 4.8 percent. However, total factor productivity experienced a negative growth of 11 percent as all components of index remained negative except for efficiency change. Productivity of electric distribution utilities can be enhanced by adjusting their scales of operation and reducing their size through further horizontal separation.
