1. Compute the elasticities for each independent variable. Note: Write down all of your calculations. The demand estimation as follows: QD = -3,500 - 150P + 30A + 75PX + 10Y. When P=300, A=750, PX=200, and Y=10,000. Placing these numbers into equation: QD=-3,500-150(300)+30(750)+75(200)+10(10,000)=QD=-3,500-45,000+22,500+15,000+100,000=89,000. Under given these numbers, we have 89,000 products demanded. Price elasticity of demand is [d(QD)/d(P)]/[QD/P]. Therefore, we take a derivative of the function subject to price, and we assume other variables do not ...
