b. Demand shifts right: preferences have shifted from hamburger to pizza and other substitutes c. Demand shifts right: the price of a substitute has risen d. Demand is unaffected; there will be a movement along the curvee, quantity demanded will fa 4. The demand for binoculars might increase, lead ing to an increase in the quantity of binoculars supplied, but no change in the supply of binoculars should occur. The UFO Sighting does nothing to change the factors that govern the supply of binoculars 5. An increase in the cost of an input used in orange production will shift the supply curve of oranges to the left, resulting in an increase in the equilibrium price and a decline in the equilibrium quantity of oranges 6. An increase in the birth rate will increase the population of potential buyers of land, and hence shift the demand curve for land to the right, resulting in an increase in the equilibrium price of land 7. The discovery will shift the demand curve for fish to the right, increasing both the equilibrium price and the equilibrium quantity of fish 8. An increase in the price of chickenfeed shifts the supply curve of chickens to the left, resulting in an increase in the equilibrium price of chickens, which are a ubstitute for beef. This shifts the demand curve for beef to the right, increasing both the equilibrium price and the equilibrium quantity of beef. 9. Compared with the rest of the year, there are more people who want to stay in hotel rooms near campus during parents' weekend and graduation weekend. Thus the demand curve shifts to the right during these weekends. This implies a higher equilibrium price for hotel rooms(and, of course, a higher equilibrium quantity of rooms rented) 10. Automobile insurance and automobiles are complements. An increase in automobile insurance rates will thus shift the demand curve for automobiles to the left Some people who would have bought new automobiles with the lower insurance rates will choose not to, maybe choosing a used car, public transportation or perhaps just getting some more miles from their current vehicle The mad cow disease announcement is likely to cause many consumers to forsake beef for substitute sources of protein--and hence produce a rightward shift in the demand for chicken. The discovery of the new chicken breed will cause a rightward shift in the supply curve of chicken. The two developments together will increase the equilibrium quantity of chicken sold in the United States, but we cannot determine the net effect on equilibrium price from the information givenb. Demand shifts right: preferences have shifted from hamburger to pizza and other substitutes. c. Demand shifts right: the price of a substitute has risen. d. Demand is unaffected; there will be a movement along the curve—i.e., quantity demanded will fall. 4. The demand for binoculars might increase, leading to an increase in the quantity of binoculars supplied, but no change in the supply of binoculars should occur. The UFO sighting does nothing to change the factors that govern the supply of binoculars. 5.
