the percent decrease in the quantity demanded exceeds the percent increase in the price
We could use the information in the table to draw a production possibilities frontier for Japan and a second production possibilities frontier for Korea. If we were to do this, measuring airplanes along the horizontal axis, then
the slope of Japan's production possibilities frontier would be -0.2 and the slope of Korea's production possibilities frontier would be -0.33
