| Abstract: | Over the past three decades, various power sector reforms have overhauled the governance of electricity generation, transmission, and distribution in almost a hundred countries. Have these reforms produced benefits? Using instrumental variables, we improve upon earlier studies and demonstrate that power sector reforms enacted between 1982 and 2008 have both had large positive effects on the availability of generation capacity and reduced transmission and distribution losses. We also show that the positive effects on generation capacity are pronounced in developing countries and that hybrid reforms falling short of privatization and free competition are effective in improving generation capacity in particular. Overall, the results show that these reforms are an effective tool to remove an important constraint on economic growth. |
