In the scenario described, cattle serve the following functions of money:
-
Unit of account - Cattle are used to price goods and services, which means they provide a standard measure for valuing transactions in the economy.
-
Medium of exchange - Cattle are widely accepted as payment for goods and services, facilitating trade.
The correct answers are:
- unit of account
- medium of exchange
(Note: While cattle may have some limitations on storing value due to their perishability and varying quality, they do not effectively meet the criteria for store of value compared to other forms of money.)
