精 Module 1-書(2022-L1V1)P22-Example 2-(1)Solution to 1,為什么要考慮For her birthday, a friend gave her a one-month club membership as a gift, and that month she saw 12 movies?為什么要拿這個(gè)條件下的12 movies與正常預(yù)算情況下可購買6 movies相比較?題干中說的是,In months that she does join the club, she sees eight movies. 而不是For her birthday, a friend gave her a one-month club membership as a gift, and that month she saw 12 movies. (2)Solution to 2,不太能理解,為什么the income effect of the price decrease has been removed by charging her the monthly fee?以及怎么結(jié)合后一句話一起理解?So the increase from six movies to eight is the result of the substitution effect.(3)Solution to 3, 因?yàn)閙ovies不是必需品essentials, 所以判斷movies are not a Giffen good ? 另外,不太能理解Solution to 3的最后一句話,The substitution effect caused her to buy two more movies, and the income effect caused her to buy an additional four movies.請解析
