This report addresses the impact of emergency shelter programs in the development of post-relief economies and in building incomes of affected populations. It provides a review and analysis of the available literature relevant to understanding the economic impact of emergency shelter programs, additional research conducted by CHF International on income development of beneficiaries of emergency shelter programs, and the first steps toward rigorous and accurate measurement of the impact of these programs on the incomes of beneficiaries. Each of these analysis provides information useful to future programmers of relief assistance.
