EC 200 Practice Problems – Supply and Demand
Due to the drought in the plain states, many ranchers have sold much of their herd for slaughter. Slaughtering the cows will result in an increase in beef supply to the market, while demand for chicken will decrease, resulting in a decrease in the equilibrium price and quantity. Hurricane Marilyn destroys much of the Jamaican sugar cane crop.
What effect does a surplus of wheat have upon the price of wheat?
Because the quantity supplied exceeds the quantity demanded, a surplus would result, bringing market forces into play. Wheat producers would lower the price of wheat in order to sell it, preferring to earn a lower price rather than letting the surplus go unsold.
What is the equilibrium price of wheat?
The equilibrium quantity is 20 million bushels and the equilibrium price is $4 per bushel.
Does this shift the supply curve for wheat?
The supply curve will shift to the left as U.S. farmers expect the price of wheat to rise in the future. ANSWER: a. A change in price will cause a movement along the supply curve, or a decrease in quantity supplied.
How might the price of corn affect the supply of wheat?
1. As the price of corn falls, so does the supply of wheat; as the price of corn rises, so does the supply of wheat.
At what price is there neither a shortage nor a surplus?
Market equilibrium occurs when the market clears, or when the quantity supplied equals the quantity demanded; in other words, the equilibrium price is the price at which neither a surplus nor a shortage exists.
What happens if supply decreases and demand is constant?
A surplus occurs when demand falls while supply remains constant, resulting in a lower equilibrium price; a shortage occurs when demand rises while supply falls, resulting in a higher equilibrium price.
What happens to demand when the population increases?
Similarly, changes in population size can affect demand for housing and a variety of other goods, each of which will be represented by a shift in the demand curve. A lower price for a substitute reduces demand for the other product.
What is equilibrium price also called?
The equilibrium price in a market is the price at which the quantity demanded and supplied of a good are equal; it is also known as the “market clearing price.”
What is equilibrium price?
When a major index experiences a period of consolidation or sideways momentum, it can be said that supply and demand forces are relatively equal, and the market is in a state of equilibrium.
What causes an increase in supply?
A change in supply, in essence, is an increase or decrease in the quantity supplied, accompanied by a higher or lower supply price, as a result of new technologies, such as more efficient or less expensive manufacturing processes, or a change in the number of competitors in the market.
Which factor can cause a shift in supply?
The supply curve shifts left or right whenever there is a change in supply, which can be caused by a variety of factors such as input prices, the number of sellers, technology, natural and social factors, and expectations.
What are the factors that shift the supply curve?
Input prices, natural conditions, technological changes, and government taxes, regulations, or subsidies are all factors that can shift the supply curve for goods and services, causing a different quantity to be supplied at any given price.
Who controls the price of corn?
On the supply side, there are basically three sources of corn in the United States: leftover stocks from the previous year, surplus corn from the previous year, and surplus corn from the previous year.
What influences the price of wheat?
Climate, yields, oil prices, lagged prices, and imports are all factors that influence wheat prices; in addition to gradually and consistently increasing global wheat demand, these market drivers are expected to have an impact on world prices and, ultimately, food security.
What influences the price of corn?
The interaction of supply and demand functions, which have historically been influenced by government agricultural policies, determines prices. This section provides information on supply and demand factors for the corn and wheat markets.
