Electricity and productivity
This data set is an unbalanced panel data made from a firm survey in 2012 (Cissokho and Seck) and the World Bank investment climate and business environment surveys in 2007 and 2014 in Senegal. Firms are classified by size using the same criteria used in the World Bank business climate surveys. The two datasets are combined in an unbalanced panel covering only manufacturing firms, on the 461 units, 41.6 percent constitute the panel. The main reason that justifies combining the two datasets is that they are based on the same core questionnaire, which is the questionnaire of the World Bank surveys. Productivty data in the data set are estimated using the stochastic frontier analysis (Greene 2005a, 2005b, 2008) and data envelopment analysis (Wilson 2008).
