How to write constraints for individual components. The budget constraint is the first piece of the utility maximization frameworkor how consumers get the most value out of their moneyand it describes all of the combinations of goods and services that the consumer can afford. Instead, it appears as a separate line item in the comma-separated column list. The . In reality, there are many goods and services to choose from, but economists limit the discussion to two goods at a time for graphical simplicity. Constraints which is also known as restrictions are mathematical expressions of the limitations that are involved in fulfilling the objectives; they are caused by scarce or limited resources which may include money, space, manpower, materials and so on.
