l>EC 200 Practice Problems - Supply and Demand

If the great is storable, and also an increase in price is meant, consumers will certainly want to buy the great today, prior to the price increases. As a result, the existing demand for the good increases, which results in a rise in the price of the good this day. See graph.

2. The drought in the plain states has actually made grain, and therefore feed, rather expensive. Many kind of ranchers cannot afford to feed their cattle, and have offered a lot of their herd for slaughter. a. What will certainly be the immediate effect of this occasion on the equilibrium price and quantity of beef? Illustprice using a supply and demand also diagram. Slaughtering the cows will certainly lead to a rise in the supply of beef to the sector, which will subsequently lead to 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 also beef are substitute products. Illustrate the result that the slaughter of the cattle herds will have actually on the equilibrium price and quantity of chicken. As the price of beef decreases, consumers will certainly buy more beef and less chicken. The demand for chicken will certainly decrease, causing a decrease in the equilibrium price and quantity of chicken. See graph.

Market for chicken c. As it happens, the slaughter of beef cattle has actually coincided via a decrease in consumers" earnings. Assuming that steak is a normal good while hamburgers are an inferior good, use a supply-and-demand diagram for either industry to highlight the linked impact of the two aforementioned events on the equilibrium price and quantity of hamburgers and steak. As consumers" revenue decreases, the demand also for normal products (such as steak) decreases while the demand also for inferior goods (such as hamburgers) boosts. Keep in mind that our conclusion from component a is still valid. A reduced price of beef will certainly increase the supply of all goods in which beef is an input. Therefore in each of the 2 industries in question we deal with simultaneous shifts in supply and demand.

Steak: S increases, 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 increases, D increases.

*
The price of steak will decrease. We cannot say for certain what will certainly occur to quantity, since that will certainly depend on the relative magnitude of the two shifts. The equilibrium quantity of hamburgers sold will increase. We cannot say for certain what will take place to the equilibrium price of a hamburger, considering that that will depend on the family member magnitude of the two shifts.

3. Assume that the sectors for sugar cane, rum, and whiskey are initially in equilibrium. Assume additionally that Hurricane Marilyn destroys much of the Jamaihave the right to sugar cane chop. Sugar cane is a principal ingredient in rum, but it is not an ingredient in whisessential. Analyze the effect of the hurricane on the markets for each of the 3 goods. Explain utilizing graphs.


Step One - The sector for sugar cane The Hurricane outcomes in a decrease in supply (at any type of provided price, sellers are no much longer able to carry out as a lot cane as they supplied to). As an outcome, the equilibrium price of sugar cane will certainly boost, and the equilibrium quantity will decrease. See graph.

Tip Two - The sector for rum Sugar cane is a principal ingredient in rum, and also it is now more expensive. An boost in the price of inputs reasons a decrease in supply. As a result, the equilibrium price of rum will increase, and also the equilibrium amount will decrease. The graph will certainly be similar to the one above.

Tip Three - The market for whiscrucial It is reasonable to assume whisvital and also rum are substitutes. Rum is now even more expensive than it provided to be (check out Tip Two). As an outcome, more consumers will buy whiscrucial rather. This will cause a rise in the demand for whiscrucial, which leads to better equilibrium price and amount of whiscrucial. See graph.
