Designing a general economic model to incentivize maintaining infrastructure in informal settlements

This paper sketches the design for a general economic model (GEM) quantifying how informal settlements (also known as slums) function and interact with ancillary urban or rural regions. The GEM is an essential tool for calculating the incentive fee payable to residents of the informal settlement to maintain housing, healthcare, schools, water, sanitation, or other infrastructure improvements and investments made by third parties and to identify potential payors or funders of the incentive fee. It is suggested that the GEM resolve limitations of traditional cost-benefit analyses (CBAs) in order to better calculate such incentive fee amounts and ascertain the parties willing to pay them. To understand how the GEM fills data gaps and helps fund national commitments to the United Nations 2030 Sustainable Development Goals (SDGs), the financial constraints on two countries, Fiji and Indonesia, as exacerbated by the coronavirus COVID-19, and Indonesia’s village finance modernization scheme (Siskeudes) are discussed.
