In a barter system, there is no standard unit of value, and the relative worth of goods and services can vary widely based on individual perceptions and preferences. It can be difficult to compare the value of goods and services, making it challenging to keep track of relative values. In a price system, goods and services are priced according to a standard currency, making it easier to compare and track their relative values. In a self-sufficient system, individuals produce and consume all goods and services themselves, so there is no need for exchange or comparison. In a monetary exchange system, goods and services are priced and exchanged based on a standard currency, making it easier to track their values.
