You have collected data for a cross-section of countries in two time periods, 1960 and 1997, say
Your task is to find the determinants for the Wealth of a Nation (per capita income) and you believe that there are three major determinants: investment in physical capital in both time periods (X1,T and X1,0), investment in human capital or education (X2,T and X2,0), and per capita income in the initial period (Y0). You run the following regression: ln(YT) = ?0 + ?1X1,T + ?2X1,0 + ?3X2,T + ?4X1,0 + ln(Y0) + uT One of your peers suggests that instead, you should run the growth rate in per capita income over the two periods on the change in physical and human capital. For those results to be a parsimonious presentation of your initial regression, what three restrictions would have to hold? How would you test for these? The same person also points out to you that the intercept vanishes in equations where the data is differenced. Is that true? What will be an ideal response?
Suppose the price of beef declines by $0.50 per pound at the supermarket. Consumers of beef immediately increase their purchases of beef. This illustrates:
a. the fact that beef is an inferior good. b. the cross-elasticity effect of a price decrease. c. the substitution effect of a price decrease. d. the fact that beef is an economic bad. e. the income effect of a rise in price.
