The demand curve for X goods is Xd=100-10P and the supply curve is MCx=1. The demand curve for Y goods is Yd=100-20P and the supply curve is MCy=1. A tax of $2 per unit on goods X and no tax on goods Y.
a. Calculate tax revenues and excesses in X goods.
b. Explain the total tax revenue and excess burden if you reduce the tax on goods X to one dollar and impose one dollar per unit on goods Y.
c. Explain which tax system is more desirable.

Solutions

Expert Solution

Part (A)

when no tax is imposed on good X

equilibrium at point when demand equals supply

at free market equilibrium of good X, 90 units of good X are sold at price of $1

tax of $ 2 per unit is imposed on good X

Sellers receive $ 1 for each unit of good X while buyers pay $ 3 for each unit of good X

Part (B)

in case of $ 2 , a tax of $ 1 is imposed on good X

Sellers receive $ 1 for each unit of good X while buyers pay $ 2 for each unit of good X

when no tax is imposed at equilibrium demand equals supply

at free market equilibrium of good Y, 80 units of good Y are sold at price of $1

tax of $ 1 per unit is imposed on good Y

Sellers receive $ 1 for each unit of good Y while buyers pay $ 2 for each unit of good Y

Part (C)

when tax of $ 2 is imposed on good X and no tax is imposed on good Y

when tax of $ 1 is imposed on both good X & good Y

tax revenue is equal for both tax systems but deadweight loss is lower in case of second tax system (part B)

so tax system 2 (part B) is more desirable

Suppose the demand curve for beer is given by QD = 50 − 10P and the supply curve for beer is given by QS= −10 +20P. Now, the government imposes a price ceiling of $1 in the market for beer. As a result, the producer surplus decreases. Now, a part of the initial producer surplus is part of the deadweight loss and a part of it is transferred to consumers. a) What is the amount of producer surplus that is...
