PROBLEM #6 For parts a through c of this problem, state whether supply or demand will change (only one will change in each case). State whether the equilibrium quantity and price will (rise or (fall in the indicated market as a result of each change described. Illustrate each answer with a graph using demand-and-supply graphical analysis. Briefly explain each answer. Follow the separate instructions for part d. a. Following recent hurricane activity in the Caribbean, consumers are more reluctant to take vacations to islands in the Caribbean. Determine the impact on the market for airline tickets to the Caribbean islands. b. Many restaurants continue to close in downtown Boston following the pandemic. Determine the impact of these closures on the restaurant market in Boston. C. Suppose the price of beef rises significantly, and that consumers view chicken as a good substitute for beef. Determine the impact on the market for chicken. d. For this part of the problem, consider two changes impacting the market for cars. Suppose the price of steel, a key input in the production of cars, falls due to the effect of international trade policies. At the same time, as people work from home and bike more, families choose to get by with one car instead of two. Which of these changes will impact the demand and which will impact the supply in the market for cars? Without any further information, can we predict the direction of change in equilibrium quantity? Without any further information, can we predict the direction of change in equilibrium price? Demonstrate your answer graphically using supply-and-demand analysis and briefly explain your
