Uses Grameen Bank to teach how to design or evaluate a substitute when a business model depends on an institution that is missing from a market. Covers naming the function the institution performs, identifying the information or enforcement it supplies, specifying an arrangement that could supply the same thing, and finding the externality the substitute creates.

Take a business model that cannot operate in a given market because an institution it depends on is missing, and design or evaluate a substitute, by naming the specific function that institution performs, identifying what information or enforcement it supplies, and specifying what arrangement could supply the same thing at acceptable cost.
