An economist estimates that a market has a demand curve of the form P = 26 - (0.867) Q and a supply curve of the form P = 0.5 + (1.21) Q. (See the curves graphed in the figure below.) Accordingly, she estimates that the

Research suggests an increase in consumption of a particular fast food item is responsible for high number of obesity cases. As a result, the government of that State is considering an imposition of $1 tax. Monthly demand and supply for this good are QD=21-1P and QS= -1+1P respectively. Draw the demand and Supply curve for fast food before the tax is imposed. Calculate the equilibrium price and quantity, consumer and producer surplus, and label them on the graph. Calculate the price elasticity of demand and supply for fast food. If the State government imposes a tax, who will bear the most of the burden of the tax? Suppose that the State government finally imposes a $1 tax on fast food. What will the new equilibrium price and quantity? Include the tax on your graph. Calculate the consumer and producer surplus and label them on the graph. Is there any deadweight loss resulting from the tax on that…arrow_forward
- The demand and supply functions for three (03) goods are given as follows: Dx = 100-3Px+Py+3Pz Dy = 80+Px-2Py-Pz Dz = 120+3Px-Py-4Pz Sx = -10+Px Sy = -20+3Py Sz = -30+2Pz The equilibrium prices and quantities of all three goods are? The government decides to: a) Impose a 25% Tax on X? b) Impose a 5 Rs /unit Tax on Y? c) Give a 10% subsidy on good z? Analyze the impact of each of these policies separately on equilibrium prices and quantities? Analyze the impact of each of these policies separately on equilibrium prices and quantities?

Suppose the demand for lawn mowing in Joe's neighborhood is: QD = 46 - 2P and that the supply of lawn mowing (Joe's willingness to mow lawns) is: Qs = 14 + P. The market-clearing price of lawn mowing is $ 20 per lawn and the market-clearing quantity is 6 lawns. (Enter your responses rounded to two decimal places.) The corresponding consumer surplus is $arrow_forwardSuppose the supply of a good is given by the equation Q = −6+2P and the demand for the good is given by the equation QD = 14 - 2P, where quantity (Q) is measured in millions of units and price (P) is measured in dollars per unit. The equilibrium quantity in this market is 4 million PRICE (Dollars per unit) the following graph, plot the demand curve using the blue line (circle symbol) and plot the supply curve using the orange line (square symbol). Then place the black point (plus symbol) at the equilibrium price and quantity.

With the onset of the coronavirus pandemic, many people became fearful of going to restaurants for full-service, sit-down meals. C) As the demand decreased, the supply turned into a surplus. As the demand for restaurant meals has decreased, there is an excess of restaurant meals. D) Based on your answer to part c., will the equilibrium quantity of restaurant meals go up or will the equilibrium quantity of restaurant meals go down? Explain your answer. In particular, will your answer focus on quantity demanded or will it focus on the quantity supplied? E) Result: state the effects of the fear of eating in restaurants on the equilibrium price and quantity of restaurant mealsarrow_forwardThe demand and supply functions for two independent goods are given by: QD₁ = 502P₁ + P₂ and QD2 = 10 + P₁ - 4P₂ Qs1 = -21 + P₁ and Qs2 = -10 + 5P₂ Show that in equilibrium: R=2 Find the equilibrium prices.arrow_forward
