Suppose that the economy has 10 workers. The supply curve of workers is given by: P=0.1Q+100. Also, there are two types of consumers: A and B. Each A has the following demand curve: Q=1000-5P. The demand curve of B given by: Q=100-0.5P. Assume that there are 10 A and 100 B in this market.

a. Calculate the aggregate demand and aggregate supply curves.

b. Calculate the equilibrium price and quantity.

c. Calculate the consumer's surplus, the producer's surplus and total surplus.

d. Suppose that the government decides to subsidize product. How much subsidy is needed for lowering the market price to 100 (for consumers). Calculate the consumer, producer and society surplus.

e. (ignore d) Suppose that the government impose tax of 20 RMB per product. Calculate the new price and quantity at equilibrium. Calculate the deadweight loss of the economy.

Expert Solution

Part (A)

There are 10 workers in the economy with supply function

there are two types of consumers: A and B

Part (B)

Part (C)

PArt (D)

subsidy is implemented by government which reduces price paid by consumers to

government should implement a subsidy of $ 100

Part (E)

price paid by consumers is $ 160 and price paid by producers is $ 140

Before tax price is $ 150

Therefore, tax burden is shared equally between consumers and producers

after tax quantity is 4000 units

Suppose you have a demand curve of P = 10 - Q and a supply curve of P = 2 + Q. If the government imposes a tax of $8 per unit of quantity sold on the sellers in this market, then what is the market quantity traded as a result of the tax? Then, what are the consumer surplus, producer surplus, and deadweight loss (after the $8 tax)?

A small country’s demand curve is given by Q=10-(P/2) and its supply curve is given by...

A small country’s demand curve is given by Q=10-(P/2) and its supply curve is given by Q=P-5. Assume that there is initially free trade and that the world price under free trade is $7. If an import quota of 1.5 is now introduced in this country, what will be the change in this country’s government revenue (everything else being equal) if foreign firms have to acquire an import licence at full value? A increases by 7 B increases by 3...

Suppose the supply curve for steel is given by P=Q and the demand for steel is...

Suppose the supply curve for steel is given by P=Q and the demand for steel is given by P=100- 2Q. The production of steel is associated with a constant external cost of $10 per unit. a. Calculate the private equilibrium. What are equilibrium price and quantity? b. What is the deadweight loss associated with the private equilibrium. Calculate and draw a sketch.

Suppose the demand curve in a city is given by P = 100 - 2Q, where P denotes price and Q the local GDP. The supply curve is given by P = 10 + Q. Now Suppose that due to an initial impulse of ΔX = 10 (Increase in exports) and further induced increases in local incomes the new induced demand curve changes to P = 150 - 2Q. Where are the local GDP and the corresponding income multiplier if...

Given a demand curve of P = 56 - 1.25Q and a supply curve of P...

Given a demand curve of P = 56 - 1.25Q and a supply curve of P = 6 + 1.25Q, with a subsidy of 30, solve for the dollar value of the added surplus for both consumers (Answer 1) and producers (Answer 2) arising from the subsidy.

Given a demand curve of P = 61 - 1.25Q and a supply curve of P...

Given a demand curve of P = 61 - 1.25Q and a supply curve of P = 1 + 0.25Q, with a subsidy of 6, solve for the dollar value of the added surplus for producers (PS) arising from the subsidy. You can use the information that the extra consumer surplus (CS) is 210.

Suppose the internal supply curve is given by P=6+(2/3)Q, the internal demand curve is given by...

Suppose the internal supply curve is given by P=6+(2/3)Q, the internal demand curve is given by P=12-(1/3)Q, and the social supply curve is given by P=9+(2/3)Q. a. (3 points) Algebraically solve for the coordinates of the market equilibrium and the coordinates of the social optimum. b. (3 points) Labelling everything, graph these three curves and clearly indicate the market equilibrium, the social optimum, and the triangle corresponding to the deadweight loss. (In the interest of time, you do NOT have to draw...

Suppose there are 100 workers in the economy, with overall labour supply LS=100. There are two sectors, the labour demand in A is given by LDA=120-2wA and labour demand in B is given by LDB=100-4wB.

Suppose there are 100 workers in the economy, with overall labour supply LS=100. There are two sectors, the labour demand in A is given by LDA=120-2wA and labour demand in B is given by LDB=100-4wB.A. If the neoclassical model of perfect competition holds, such that wA = w and wB = w, the formula for the total aggregate labour demand is: LD= ________ (simplify formula before entering). Graph this aggregate demand along with the aggregate supply. The competitive wage will...

Demand is given by the equation QD=100-P; supply is given by QS= 4P Suppose the world price of each unit is $25. Now assume that this economy is open to world trade. How many units will they import or export? Calculate the consumer surplus, producer surplus and total surplus. Help me solve, A Continue to assume that this economy is open to world trade. Suppose the government enacts a tariff off $2 per pound of cocoa beans. Calculate the consumer...
