l>EC 200 Practice Problems - Supply and also Demand

If the excellent is storable, and an increase in price is meant, consumers will certainly desire to buy the great this day, before the price rises. As a result, the existing demand for the great increases, which outcomes in an increase in the price of the excellent today. See graph.

2. The drought in the simple claims has actually made grain, and also therefore feed, quite expensive. Many kind of ranchers cannot afford to feed their cattle, and also have marketed a lot of their herd for slaughter. a. What will certainly be the immediate impact of this occasion on the equilibrium price and also quantity of beef? Illustprice making use of a supply and also demand also diagram. Slaughtering the cows will certainly result in a boost in the supply of beef to the market, which will consequently cause a decrease in the equilibrium price of beef and a boost in the equilibrium quantity of beef. See graph.

Market for beef

b. Chicken and beef are substitute products. Illustprice the impact that the slaughter of the livestock herds will certainly have on the equilibrium price and quantity of chicken. As the price of beef decreases, consumers will buy more beef and less chicken. The demand also for chicken will decrease, leading to a decrease in the equilibrium price and quantity of chicken. See graph.

Market for chicken c. As it happens, the slaughter of beef livestock has coincided with a decrease in consumers" revenue. Assuming that steak is a normal excellent while hamburgers are an inferior excellent, usage a supply-and-demand diagram for either sector to illustrate the unified effect of the two abovementioned occasions on the equilibrium price and amount of hamburgers and steak. As consumers" income decreases, the demand for normal products (such as steak) decreases while the demand for inferior products (such as hamburgers) increases. Keep in mind that our conclusion from component a is still valid. A lower price of beef will certainly rise the supply of all items in which beef is an input. Thus in each of the two markets in question we deal with simultaneous shifts in supply and demand also.

Steak: S boosts, D decreases.

You are watching: If the demand for tires goes down when the price of gas goes up, then tires and gas are:

Hamburgers: S rises, D rises.

The price of steak will certainly decrease. We cannot say for certain what will happen to quantity, because that will certainly depfinish on the loved one magnitude of the 2 shifts. The equilibrium amount of hamburgers sold will certainly rise. We cannot say for certain what will take place to the equilibrium price of a hamburger, since that will depend on the relative magnitude of the two shifts.

3. Assume that the markets for sugar cane, rum, and also whisessential are initially in equilibrium. Assume further that Hurricane Marilyn destroys a lot of the Jamaihave the right to sugar cane chop. Sugar cane is a primary ingredient in rum, yet it is not an ingredient in whisvital. Analyze the result of the hurricane on the sectors for each of the three items. Exordinary making use of graphs.


Step One - The industry for sugar cane The Hurricane outcomes in a decrease in supply (at any offered price, sellers are no much longer able to administer as a lot cane as they supplied to). As a result, the equilibrium price of sugar cane will increase, and the equilibrium quantity will certainly decrease. See graph.

Tip Two - The sector for rum Sugar cane is a major ingredient in rum, and it is currently even more expensive. An rise in the price of inputs reasons a decrease in supply. As a result, the equilibrium price of rum will rise, and the equilibrium amount will decrease. The graph will certainly be comparable to the one over.

Tip Three - The sector for whiskey It is reasonable to assume whisvital and also rum are substitutes. Rum is currently even more expensive than it supplied to be (see Tip Two). As a result, more consumers will certainly buy whisvital rather. This will reason a boost in the demand also for whisvital, which leads to better equilibrium price and quantity of whiscrucial. See graph. Market for whiskey
