In Mozambique, households consume a mix of energy sources to satisfy their needs for lighting and cooking and, for wealthier households, other domestic necessities such as refrigeration. The domestic energy mix depends on the prices of the sources and on the capability of the household to invest in the energy-consuming appliances required to satisfy those needs. Based on data from a household survey carried out in Mozambique during 2002/3 (IAF), this paper calculates the price and the income elasticities of demand for domestic energy, using an econometric method developed by Deaton. The calculations are made for all households at the national level, differentiating for urban and rural households, and for the northern households of Mozambique. In the econometric formulation, proxies for the ownership of energy appliances per household are used, allowing a simple evaluation of the effects of asset ownership on the demand for energy. Own- and cross-price elasticities for five individual domestic sources are obtained: low-grade sources such as firewood and charcoal are less elastic (elasticities of â0.41 and â0.28 respectively) than candles, kerosene and electricity (respectively â0.88, â0.79 and â0.60).Income elasticities are respectively 0.45, 0.32, 0.93, 0.84 and 0.69, placing firewood and charcoal as the less responsive to income variations and candles and kerosene as the most responsive. We also comment on the factors influencing domestic energy transition.
⺠We present the elasticities of domestic energy consumption for Mozambique. ⺠We discuss the ownership of appliances in the households' energy choices. ⺠We provide insights into the energy ladder for Mozambican households. ⺠We used Deaton's econometric method to estimate elasticities of domestic energy. ⺠We utilized proxies to represent the ownership of energy-consuming appliances.
