A1.
a. A decrease in the average price of new Japanese automobiles.
A decrease in average price of new Japanese automobiles will result in an increase in quantity demanded of new autos. It is represented by downward movement along a given demand curve. Since demand is elastic, percent change in increase in quantity will be higher than corresponding percent change in average prices.
b. A fall in Japanese interest rates.
A fall in Japanese interest rates will reduce the cost of using automobiles (for who buy autos on loan). Demand for new autos will increase. There will be outward shift in demand curve. ...
