l>EC 200 Practice problems - Supply and Demand

If the an excellent is storable, and an increase in price is expected, consumers will desire to purchase the an excellent today, before the price increases. As a result, the existing demand because that the an excellent increases, which outcomes in rise in the price the the good today. Check out graph.

2. The dryness in the level states has made grain, and also therefore feed, quite expensive. Numerous ranchers cannot afford come feed your cattle, and have sold lot of their herd because that slaughter. A. What will be the immediate impact of this occasion on the equilibrium price and also quantity that beef? show using a supply and demand diagram. Slaughtering the cows will result in rise in the supply of beef to the market, i beg your pardon will consequently lead come a decrease in the equilibrium price that beef and rise in the equilibrium amount of beef. View graph.

b. Chicken and beef room substitute goods. Highlight the effect that the slaughter the the cattle herds will have actually on the equilibrium price and also quantity that chicken. together the price the beef decreases, consumers will buy an ext beef and less chicken. The need for chicken will decrease, resulting in a to decrease in the equilibrium price and also quantity of chicken. Check out graph.

market for chicken c. Together it happens, the slaughter the beef livestock has corresponded with a to decrease in consumers" income. Assuming that steak is a normal great while hamburgers are an worse good, use a supply-and-demand diagram because that either sector to illustrate the an unified effect of the two abovementioned events on the equilibrium price and also quantity that hamburgers and also steak. as consumers" income decreases, the demand for normal products (such together steak) decreases while the need for inferior products (such together hamburgers) increases. Keep in mind that our conclusion from part a is still valid. A reduced price that beef will rise the supply of all products in i beg your pardon beef is one input. Thus in every of the two industries in inquiry we address simultaneous move in supply and demand.

Steak: S increases, D decreases.

You are watching: If the demand for a product decreases, then we would expect

Hamburgers: S increases, D increases.

The price that steak will certainly decrease. Us cannot say for certain what will occur to quantity, because that will count on the relative magnitude that the two shifts. The equilibrium amount of hamburgers marketed will increase. Us cannot say for sure what will happen to the equilibrium price that a hamburger, because that will count on the loved one magnitude of the two shifts.

3. Assume the the industries for street cane, rum, and whiskey are originally in equilibrium. Assume additional that Hurricane Marilyn destroys lot of the Jamaican sugar cane crop. Sugar cane is a major ingredient in rum, but it is no an ingredient in whiskey. Analyze the impact of the hurricane on the industries for every of the 3 goods. Define using graphs.


Step One - The sector for sugar cane The Hurricane results in a decrease in it is provided (at any type of given price, sellers space no longer able to administer as much cane together they offered to). As a result, the equilibrium price of sugar cane will certainly increase, and also the equilibrium amount will decrease. See graph.

Step 2 - The market for rum street cane is a principal ingredient in rum, and it is now much more expensive. Rise in the price the inputs causes a diminish in supply. As a result, the equilibrium price that rum will increase, and also the equilibrium amount will decrease. The graph will be similar to the one above.

Step three - The sector for whiskey the is reasonable to i think whiskey and also rum room substitutes. Rum is now much more expensive 보다 it used to be (see step Two). As a result, an ext consumers will certainly buy whiskey instead. This will certainly cause rise in the demand for whiskey, which leader to greater equilibrium price and quantity that whiskey. See graph. Sector for whiskey
