In class, you learned how the budget constraint changes when there is a unit tax on good x. With a unit tax (or quantity tax), the consumer has to pay a certain amount \tau for each unit of good x that he purchases (px -> px + \tau ). Now we consider a value tax (or ad valorem tax), where the consumer has to pay a certain percentage \tau of the value of good x, on top of the price of good x (px -> (1+\tau )px) (e.g., think of the Ontario sales tax of 13%). Show graphically how the budget constraint changes when the government imposes a value tax on good x (label everything!). [5 points]
