A traditional economy is an economy wherein the people primarily subsists on growing their own food and produce. Usually, just about the right amount is produced and if there is any excess, it is given to the local lords. Also, bartering is the main practice of trading in a traditional economy. In a command economy, it is a dictator who will dictate who should make what and how much of a certain product should be made. The government will also decide at what price the people will price the products.
