As a result of the government setting a price of $7 for corn, there could be several potential outcomes:

1. Surplus: If the market price of corn is lower than the government-set price, this can lead to a surplus. With a price of $7 per bushel, producers will be encouraged to supply more corn because they can make a higher profit. However, consumers may not be willing to purchase as much corn at the higher price. This can result in an excess supply of corn, leading to a surplus in the market.

2. Shortage: In some cases, if the government sets a price above the market equilibrium, it can result in a shortage. If the market price of corn is $5 per bushel and the government sets a higher price of $7, consumers may be less willing to purchase corn at the higher price. This can lead to a decrease in demand and potentially a shortage in the market, as producers may not be incentivized to supply as much corn at the lower market price.

3. Black market: When there is a significant discrepancy between the government-set price and the market price, a black market may emerge. If the government sets a higher price of $7, but consumers are unwilling to pay that much, some individuals may seek alternative sources for cheaper corn. This can lead to illegal or informal markets where corn is exchanged at prices lower than the government-set price.

It's essential to note that government intervention in pricing, such as setting a price floor or price ceiling, can have unintended consequences and disrupt the natural supply and demand dynamics of a market.
