Mono-product economies are those that produce one main commodity. This means that the economy is heavily reliant on the production and export of this one commodity, which can be either a natural resource or a manufactured product. Examples of mono-product economies include countries that rely heavily on the production and export of oil, such as Saudi Arabia or Venezuela, or countries that rely on the production and export of agricultural products, such as coffee or cocoa. Mono-product economies can be vulnerable to fluctuations in the global market for their one commodity, which can lead to economic instability and hardship for the population.
