Daily demand for gasoline at a Gas Station is described by Q = 980 - 300p, where Q are gallons of gasoline sold and p is the price in dollars. Gas Station's supply is Q = -2,980 + 3,000p. Suppose the state government places a tax of 18 cents on every gallon of gasoline sold. (a) What are the before-tax and after-tax equilibrium quantities of gasoline Q? (b) What are the changes in consumer's and producer's surplus due to tax?

A state tax on portable electronic devices causes sales of a single model of a handheld calculator to decrease from 80 to 70 per week. The tax is assessed as a tax on sellers when they receive the units from suppliers. Drag the appropriate curves (including the Quantity curve) to show the effects on the market.

Assume the market for good Y is in equilibrium. (a) Draw a correctly labeled demand and supply graph for good Y. Label the equilibrium price PePe and the equilibrium quantity QeQe. (b) Assume the government imposes a per-unit tax on good Y. On your graph in part (a), show each of the following after the tax has been implemented. (i) The equilibrium price labeled PNPN and the equilibrium quantity labeled QNQN (ii) The area representing the change in consumer surplus, shaded completely (c) Will the price paid by consumers increase by the same amount as the tax? Explain. (d) Will the loss in consumer and producer surplus be greater than, less than, or equal to the tax revenue collected by the government? Explain.
When the price is 10 TL for each pack of cookies, the supply is 250 thousand and the demand is 120 thousand boxes. When the price is 9,5 TL for each pack of cookies, the supply is 200 thousand and the demand is 240 thousand boxes. Since the price-demand and supply-demand equations are linear; Calculate the producer and consumer annuity and find and interpret the market equilibrium point after-tax if the consumer is taxed at a rate of 0,75 TL per product.

Suppose demand is D and supply is S0 so that equilibrium price is $10. If an excise tax of $6 is imposed on this product, what happens to the equilibrium price paid by consumers? The price received by producers? The number of units sold?Equilibrium price paid by consumers: $ Price received by producers: $ Number of units sold:
The demand (D) and supply (S) function for a commodity are P =100 – 2Q and P = 10 + Q, respectively. (a) Find the equilibrium price and quantity. That is, find the price and quantity where the D and S functions intersect. (b) A new 10% tax is imposed on this commodity. Find the burden of the tax on demanders and the burden on suppliers. Also find the total taxes. [In order to insure that we all do this problem in the same way, let’s assume that the tax is imposed on the supply side of the market. In addition, the burden of the tax on demanders is the difference in price demanders pay when the tax is in existence less the price they paid when there was no tax. The burden on suppliers is the difference in price suppliers received when there was no tax and the net price (after remitting tax to the government) they receive when the tax is in existence.]
The inverse demand for table salt is p = 200qd+1 , while the inverse supply of table salt is p = 10+ 2qs. a. Find the equilibrium price of table salt before AND after the imposition of a 40% ad valorem tax on the consumers of table salt. b. Describe the distribution of the burden (incidence) of this ad valorem tax between consumers and producers. c. Find and interpret the price elasticity of supply (es) at the after-tax equilibrium price and quantity.
Consider an ad-valorem tax on a good X. The Demand for good X is constant elasticity with elasticity -2. The Supply for good Y is constant elasticity with elasticity 3. Consider the same setting as for the previous question. When a tax of 1% of the price is imposed on good X, then equilibrium quantity of X exchanged declines by what percentage?
Willy the Worker has unavoidable personal commitments taking 8 hours per day. He can choose to work or to play (i.e., take leisure, a normal good) in the remaining hours. Being a graduate in Economics, he can charge $100 per hour for his consulting services when he chooses to work. The government's income tax system has a 0% tax rate for daily incomes from $0 to $ $600 per day; above $600 per day, the tax rate is 20%. Willy has a certain Utility Function U(L, I) where L = leisure playtime and I = Income. His Marginal Rate of Substitution is known to be derived from this equation: MRSL/I=2I/L. (Note that the "price" of Income is $1.) Willy thinks he pays enough taxes via the excise taxes on things he buys. So he decides to work the maximum number of hours he can without paying any income taxes. According to our Indifference Theory model, is Willy maximizing his satisfaction with his "no tax" choice, or should he work fewer hours?
