B. an increase in the price of good Y causes an increase in the consumption of good X. C. a decrease in the price of good X causes an increase in the consumption of good Y. D. a decrease in the price of good X causes a decrease in the consumption of good Y.
C
If the law of demand holds for an inferior good, A. then the income effect of a price change is greater than the substitution effect. B. then there is no income effect of a price change. C. then the substitution effect of a price change is greater than the income effect. D. then the income effect of a price change reinforces the substitution effect.
C
Which of the following statements is correct? A. The substitution effect of a price change is qualitatively different for normal and inferior goods. B. For an inferior good, the substitution effect of a price decrease is to consume less of the good. C. For an inferior good, the substitution effect of a price increase is to consume more of the good.
