Abstract

The paper aims to test the hypothesis whether high tariffs lead to a high efficiency of electricity suppliers. The authors test this hypothesis on a case of 29 Ukrainian electricity distribution companies. Using the data envelopment analysis and correlation coefficients, grouping the super-efficiency scores, the authors found that in most regions of Ukraine the increase in tariffs no longer leads to increased efficiency. This indicates a weakness of tariff policy in most of the electricity distribution companies. The case showed that rising tariffs can cause a decline in revenue, net income and an increase in accounts payable. This does not allow the electricity distribution companies to provide high efficiency.

Apart from this, despite improving the financial performance of most companies, the electricity distribution industry in Ukraine as a whole remains unprofitable. However, the high percentage of foreign investors in this industry indicates a significant potential for increasing the efficiency of Ukrainian energy companies. The government control of the electricity distribution companies more often provides medium efficiency, while the management by foreign investors often provides a high efficiency. The absence of the major owner and the presence of blocking stakes in any investor (government, domestic or foreign investors) has a negative impact on the efficiency of energy companies.

Although the case is limited to one country and 29 companies, this study can serve as a model for wider testing of the research hypothesis in other markets and countries.
