The cost of cashmere plummets and most of the people start employing this once costly material as pillow covers and to knit sweaters for their pets. This is an illustration of: (i) The income effect. (ii) The change in preferences and taste. (iii) The law of diminishing marginal utility. (iv) The substitution effect. (v) The change in producer’s expectations.
Can someone please help me in finding out the accurate answer from the above options.
