題目:Roger's utility function is U = min{a1,a2}min{b1,b2}, where a1 and a2
are the number of piano lessons he consumes this year and next and b1
and b2 are the number of ice skating lessons he consumes this year and
next. The price of piano lessons is ＄10 each and the price of ice
skating is ＄4 each. The prices won't change, but the interest rate is
7%. If Roger consumes 20 piano lessons this year, how many ice-skating
lessons will he consume next year?
我的想法: 這題我是覺得它的效用是兩個完全互補所形成的一個cobb-dogulas效用
函數。我切入的角度是從跨期預算限制式求解，但是卡在不知道如何求
所得，也就是endowment的價值總額。拜託各位指點一下 謝謝。
