Does energy aid improve energy efficiency in developing countries?

Abstract

The study examines the effect of energy aid on the energy efficiency of 70 developing countries in the period 1990–2016. We consider two-stage least squares identification strategy to examine the energy aid-energy efficiency nexus empirically. Energy aid is instrumented by similar voting preferences between donors and recipient countries in the United Nations General Assembly. Our finding suggests that energy aid has a significant positive effect on the energy efficiency of aid recipient countries. The result is robust with different sensitivity checks, such as using alternative measures of energy efficiency, alternative measures of energy aid, alternative estimation methods, and dropping outliers.

Notes

  1. Other noteworthy studies that look at specific channels of foreign aid are McPherson and Rakovski (2001) and Gomanee et al. (2002). They apply a multi-equation system model to find that aid influences economic growth through the investment channel.

  2. Source AidData database. Link: http://aiddata.org/.

  3. It is common to use this scaling procedure in the aid effectiveness literature (e.g. see Wilson 2011; d’Aiglepierre and Wagner 2013). Further, following Arndt et al. (2010), we treat zero-valued aid observations as zeroes, rather than missing.

  4. This paper uses only bilaterally committed energy aid which is coded as 230 on the AidData database. The reason we use only bilaterally committed energy aid is that the affinity index (an instrument used for energy aid) has a direct effect on bilateral energy aid but not on multilateral energy aid. However, in other unreported results, we regress overall energy aid (i.e. bilaterally plus multilaterally committed energy aid) on energy efficiency using OLS and GMM empirical strategies. The results are qualitatively similar to the baseline results. The results are available upon request.

  5. We have followed Belke et al. (2011) and Beckmann et al. (2014) to empirically test the presence of reverse causality between energy efficiency and energy aid using a panel cointegration approach. The causality tests show the presence of a bi-directional causal relationship between energy efficiency and energy aid. We do not report the panel cointegration results due to paucity of space. However, the results are available upon request.

  6. We also run the model using fixed effect and random effect estimations, and the results are qualitatively similar to the OLS findings (results are available upon request).

  7. In other unreported results, we have conducted various linearity and nonlinearity tests (e.g. logistic and exponential transition functions) following Beckmann et al. (2014) before we consider a linear relationship between energy efficiency and energy aid as our preferred specification. The results show that the hypothesis of linearity is not rejected.

  8. Using the lag values of foreign aid is well accepted in the literature (e.g. Mishra and Newhouse 2009). We regress energy efficiency on different lagged values of energy aid and find qualitatively similar results with the baseline findings (see robustness check in Sect. 5).

  9. It is important to mention that the time fixed effect term captures, among other things, the effect of structural breaks that can potentially arise when the number of periods is relatively large. Similarly, Westerlund (2006) suggests that the probability of a structural break in the cointegration relation increases with the length of the time-series dimension of the panel. Hence, we have performed a unit root test by considering endogenous structural breaks Zivot–Andrews and Clemente–Montañés–Reyes tests for energy efficiency and energy aid, and the results show that most of the countries reject the null hypothesis of the unit root for both variables. The results for these tests are available upon request.

  10. It is important to note that Dalgaard et al. (2004) and Djankov et al. (2008) examine the impact of overall aid on growth.

  11. The presence of aid elements in the error term of Eq. (1) may violate one of the Gauss–Markov assumptions, such as the expected value of the aid variable and the error term may not be zero, and thereby create an endogeneity issue (see Cragg and Donald 1993).

  12. We also run regressions using the affinity index of other bilateral donors including Australia, France, Germany, Italy, Japan, Korea, Netherlands, Norway, Spain and Sweden as instrumental variables of energy aid, and the results are qualitatively similar to the results reported in column 3 of Table 2 (results available upon request). However, it is worth noting that these donors have much missing data on the affinity index, as compared to USA, Canada, UK and China, which may potentially lead to ambiguous conclusions. Therefore, our analysis mainly focuses on the findings obtained from the use of the affinity indices of USA, Canada, UK and China as instruments of the aid variable.

  13. Appendix” shows the amount of energy aid provided by the largest bilateral donors.

  14. The outliers are treated using Hadi (1992) procedures.

  15. It is important to mention that aid targeted to power generation may not exert a potential effect on energy efficiency as its main purpose is related to energy generation rather than energy consumption. However, descriptions of project activities provide some evidence that power generation aid is also allocated for promoting energy efficiency. For example, Uganda has received $US 28.402 million aid capital targeted to assisting technical managers for energy-efficient stoves concentrates on implementing and securing standards and quality regarding the production process, to increase efficient and environmentally sustainable energy supply and to promote renewable energies and energy efficiency. This evidence can be taken as one of the reasons for obtaining a positive and significant effect of power generation aid on energy efficiency in the recipient countries.

  16. In other unreported results, we also examine the effect of both energy research and development and power generation aid on fossil fuel energy consumption (% of total). The results are qualitatively similar to the findings reported in Table 3 and available upon request.

  17. In other unreported results, we have used alternative measures of the disaggregated forms of energy aid (energy research and development and power generation aid) and then examined their effects on energy efficiency. The findings are qualitatively similar to those reported in Table 3 and available upon request.

  18. In other unreported results, we checked this relationship by taking a 5-year lag of energy aid and the results are qualitatively similar.
