Answers
Step-by-step explanation:
A Robinson Crusoe economy is a simple framework used to study some fundamental issues in economics.[1] It assumes an economy with one consumer, one producer and two goods. The title "Robinson Crusoe" is a reference to the 1719 novel of the same name authored by Daniel Defoe.
As a thought experiment in economics, many international trade economists have found this simplified and idealized version of the story important due to its ability to simplify the complexities of the real world. The implicit assumption is that the study of a one agent economy will provide useful insights into the functioning of a real world economy with many economic agents. This article pertains to the study of consumer behaviour, producer behaviour and equilibrium as a part of microeconomics. In other fields of economics, the Robinson Crusoe economy framework is used for essentially the same thing. For example, in public finance the Robinson Crusoe economy is used to study the various types of public goods and certain aspects of collective benefits.[2] It is used in growth economics to develop growth models for underdeveloped or developing countries to embark upon a steady growth path using techniques of savings and investment.[3]
