The key assumptions in Becker's economic model of marriage are:

1. People are rational and maximise their satisfaction: This assumption is based on the economic principle of rational choice theory, which assumes that individuals always make prudent and logical decisions that provide them with the greatest benefit or satisfaction.

2. Individuals are required to make choices under constraint due to limited resources: This is another fundamental economic principle that applies to Becker's model. It assumes that individuals have a limited amount of resources (time, money, etc.) and they have to make choices on how to best use these resources.

3. Couples should complement each other in their consumption and leisure preferences: Becker's model assumes that couples derive satisfaction not just from their own consumption, but also from the consumption and leisure activities of their spouse. This is known as the complementarity assumption.

4. The household is like a small factory producing goods and services that are valuable to its members and to the economy: This assumption views the household not just as a unit of consumption, but also as a unit of production. It assumes that the household produces goods and services (like meals, child care, etc.) that are valuable to its members and contribute to the economy.
