特殊偏好下的需求
每一种偏好族都塑造出各自的需求行为:柯布-道格拉斯偏好按固定份额分配支出,互补品沿着比例线趋向预算约束,替代品趋向角点,拟线性效用则无论收入如何都固定其中一种商品的数量。

Quasilinear and the income-proof good
5. The complements race
For u equal to min of 2 x1 and x2, income 60, prices 1 and 1, what does the consumer buy?
6. The substitutes rule
For u equal to 2 x1 plus x2 with prices p1 equals 1 and p2 equals 2, where does the consumer land?
7. Quasilinear income immunity
For u equal to ln x1 plus x2 with prices 1 and 1, income rises from 10 to 20. What happens to the demands?
8. Matching family to market
A consumer's purchases of tea and sugar always move together in fixed proportion regardless of prices. Which family fits?
9. Complements demand
For u equal to min of 2 x1 and x2, income 60, prices 1 and 1, compute x1, and write the number.
10. Quasilinear demand
For u equal to ln x1 plus x2 with prices 1 and 1 and income 10, compute x2 at the optimum, and write the number.
11. Complements' payoff
For u of min of 2 x1 and x2 with income 60 and equal prices, the optimum is (20, 40). What utility does it deliver?
12. The linear corner in numbers
For u of 2 x1 plus x2 with income 12 and prices 1 and 2, where does the consumer land?
13. The income-proof good
For u of ln x1 plus x2 with equal prices, income rises from 10 to 20. What happens?
14. Complements after a price cut
For u of min of 2 x1 and x2 with income 60, the price of good one falls to one half. Where is the new optimum?
15. Corner utility
For u of 2 x1 plus x2 with income 12 and prices 1 and 2, compute the optimal utility, and write the number.
16. The complement stretch
With the price of good one at one half, income 60, compute the new x2 at the optimum, and write the number.
