Two major consequences of imposing maximum prices are longer queues and the emergence of parallel markets.

The statement you provided is not a question, but I can explain the consequences mentioned in it.

1. Longer Queues: When a maximum price is imposed, it is usually set below the equilibrium price. This means that the price is lower than what the market would naturally set. As a result, the demand for the product or service increases because it is now cheaper. However, the supply decreases because producers are not willing to produce as much at the lower price. This mismatch between demand and supply results in longer queues or waiting lists, as there are more people who want the product or service than there are available.

2. Emergence of Parallel Markets: A parallel market, also known as a black market, can emerge when the official market cannot meet demand. This is often a consequence of maximum price controls. In this parallel market, goods or services are sold at higher prices than the maximum prices set by the government. This happens because the high demand and low supply in the official market create an opportunity for unofficial sellers to sell at higher prices. These sellers might be individuals who bought the product at the official price and resell it, or they might be producers selling directly in the parallel market to avoid the price controls.
