They have stable preferences (allowing them to calculate utility)
People are perfectly, or near-perfectly, informed
Atomistic
People are very egotistical
People make every decision as isolated from the past

7. Mark Granovetter on Economy and Society
It has long been the majority view among sociologists, anthropologists, political scientists, and historians that [economic] behavior was heavily embedded in social relations in premarket societies but became much more autonomous with modernization. This view sees the economy as an increasingly separate, differentiated sphere in modern society, with economic transactions defined no longer by the social or kinship obligations of those transacting but by rational calculations of individual gain. It is sometimes further argued that the traditional situation is reversed: instead of economic life being submerged in social relations, these relations become an epiphenomenon of the market. (Granovetter, 1985)

8. Avner Greif Terms
Agency: A system that allows certain people to act on behalf of other people’s interests (i.e. as “agents” for other people)
Trust: A relationship between two or more people, where these people all mutually believe that the others are disposed to act positively on their behalf
Transaction Cost: The costs necessary to make a transaction.
Transaction costs are extrinsic (not part of) the price of the product being purchased.
