ABSTRACT
Markets for goods and services are relatively underdeveloped in the earliest stages of a city's evolution, and institutional arrangements are relatively informal. As cities expand and modernize, the scale of economic activity increases, and urban institutions become more complex. Paralleling this transition is an evolutionary pattern of consumer fuel choice and home energy consumption. As cities grow beyond their earliest developmental stage and ultimately modernize, households generally shift away from the use of traditional biomass fuels and end up consuming LPG and electricity.
