What Determines Residential Electricity Demand in Urban Bangladesh? New Evidence from Panel Data- a study by Asad Islam
Designing efficient and equitable electricity pricing is a perennial challenge in developing countries experiencing rapid urbanization. Bangladesh, with its swift economic growth and urban expansion, faces a persistent gap between electricity demand and supply. This blog post draws upon the rigorous study by Hemawathy Balarama, Asad Islam, Jun Sung Kim, and Liang Choon Wang, which leverages household panel data and an exogenous value-added-tax (VAT) shock to estimate short-run price elasticities of residential electricity demand in Bangladesh’s urban centers.
Data and Identification Strategy
The authors’ dataset comprises three rounds of surveys from households in Dhaka, Jessore, and Khulna—large urban districts with similar climate regimes. The research exploits an exogenous VAT-induced change in electricity prices during the survey period, enabling a robust identification strategy through fixed-effect instrumental variable (FE-IV) estimation. This method isolates causal effects, addressing potential pitfalls like endogeneity and omitted variable bias.
Results and Heterogeneity
The study reports a short-run average price elasticity of −0.577, indicating that demand is price inelastic on average: most urban Bangladeshi households reduce consumption little when prices rise. However, the effects are not uniform. The lowest and highest consumption groups demonstrate higher price elasticity—they adjust their electricity use more in response to price changes—while middle-range consumers are less responsive.
Robustness checks further affirm these patterns using alternative instruments and extra controls for urban and temporal variation. This heterogeneity strengthens the call for differentiated tariff and subsidy design.
Policy Simulations and Implications
The authors conduct policy simulations, revealing that targeting tariff increases towards high-consumption groups could help reduce both the total demand and existing consumption inequality while retaining supplier revenue. Such differentiated pricing reforms—designed with careful attention to demand elasticity—offer a path towards balancing supply, fiscal sustainability, and social equity.
This nuanced approach contrasts with universal subsidy policies, which often benefit wealthier, high-consuming households disproportionately and can worsen supply-demand mismatches.
This study masterfully leverages a unique VAT shock for instrumental variable estimation, delivering rigorous and context-specific insights into electricity demand in Bangladesh's urban households.a893e2

ReplyDeleteThe rigorous estimation of short- and long-run price elasticities (−0.577 on average) offers invaluable insights for policymakers aiming to balance affordability and sustainability in emerging markets.c636e8
ReplyDeleteExcellent contribution to energy economics in developing contexts! The findings on elastic demand among low- and high-consumption households versus inelastic moderate users offer practical guidance for reducing demand-supply mismatches through targeted policies.
ReplyDeleteI appreciate the nuanced findings on heterogeneity across consumption groups; highlighting how low and high users are more price-responsive than moderate ones offers valuable lessons for targeted energy policies in developing economies.
ReplyDeleteLove how it uncovers heterogeneity in elasticities across consumption groups; this nuanced approach is a game-changer for equitable energy policy design in developing nations
ReplyDeleteA valuable contribution to energy economics in developing countries, showing how elasticities can reduce demand-supply gaps and inequality.
ReplyDeleteThe article’s use of household panel data to estimate price elasticities is robust, but incorporating regional variations in electricity pricing could enhance the findings’ applicability. Consider adding a discussion on how geographic factors influence demand elasticity.
ReplyDeleteFascinating use of the VAT shock as an instrument in your FE-IV model—robustly captures causality amid endogeneity. The heterogeneity insight is a game-changer for policy; perhaps extend to rural panels for broader generalizability?
ReplyDeleteThe power bill tripled. Mark unplugged everything, but the fridge hummed on. He sat in the dark, realizing some needs aren't a choice. The inelastic truth of modern life.
ReplyDeleteGreat analysis! Including a breakdown of elasticity variations by income level or region could further enrich the findings. It would help policymakers tailor energy pricing strategies more effectively.
ReplyDeleteSolid methodology using household panel data. Consider discussing potential biases in the sample or how external factors like weather might influence results. Adding a policy implication section could make the study more actionable.
ReplyDeleteClear methodology, but adding a visual (e.g., graph of elasticity trends) could make the results more accessible to non-technical readers.
ReplyDeleteThe methodology is sound, yet adding a discussion on how demand elasticities vary with income levels or energy efficiency programs could further strengthen the practical implications of the findings.
