If the price of a commodity is fixed below equilibrium, this will lead to

If the price of a commodity is fixed below equilibrium, it will lead to excess demand. This means that the quantity of the commodity demanded by consumers will exceed the quantity supplied by producers at that price level. As a result, there will be shortages of the commodity, as consumers compete with each other to buy the limited available supply. In a free market, if the price of a commodity is below equilibrium, producers would be hesitant to produce more of it as they won't be able to cover their costs. On the other hand, consumers would want to buy more of the commodity due to its lower price. This mismatch between demand and supply would lead to an increase in the price of the commodity, as the producers respond to the higher demand by producing more of it to capture the higher profits. However, when the price is fixed below equilibrium, this mechanism is not allowed to work, leading to a situation of excess demand. This may result in long queues, rationing, or even black markets. In the long run, the shortage of the commodity may also lead to a decrease in its quality as producers are forced to cut corners to reduce costs.
