vanrian的intemediate mircoecon 有个地方和别的不一样。那个the substitution effect
wiki 还有其他的书定义是
hold the utility constant, a price change that alters the buget line. 所以the buget line moves along the indifference curve from one pt to another. this is called the sub effect
但v的书里是这样定义的
rotate the buget line around the (x,y) , then the new buget line tengents another upper left indifference curve at (x1,y2) then the movement from (x y) to (x1, y1) defined as substitution effect??
为什么他们定义不一样顺便问下
