Question 1. This question looks at effects of a tax. Suppose that the demand and supply of widgets is summarized by the following equations where p is price.

Qd = 200 – 8p
Qs = 2p

Suppose now that the government imposes a tax of ten dollars per unit which is placed on demanders.

a.   What is the price paid by demanders after the tax is imposed?
b.   What is the loss in consumer surplus in dollars by consumers from the tax?
c.   What is the loss in producer surplus in dollars by producers from the tax?
d.   What is the effect on the tax on the real income of society in dollars?

Expert Solution

In order to find the price paid by the demander after imposing tax we have to find the current price and quantity at which the market is in equilibrium therefore we have to equate Qd = Qs.

200-8p = 2p

200 = 10p

200/10 = p

Therefore p = 20

As if Qd = Qs we can substitute p = 20

Qs = 2*20 = 40

1) When tax is imposed by 10 dollars in demand function Qd = 200 - 8(p+t)

= 200 - 8p- 8t

= 200 -8p - 80

Qd = 120 - 8p

Qd = Qs

120 - 8p = 2p

120 = 10p

p= 12

Qd = 120 - 8* 12

Qd = 104

The new price is 12

1. Are the effects of an increase in aggregate demand in the aggregate demand and aggregate supply model consistent with the Phillips curve? Explain 2. Explain the connection between the vertical long-run aggregate supply curve and the vertical long-run Phillips curve 3. In the long run what primarily determines the natural rate of unemployment? In the long run what primarily determines the inflation rate? How does this relate to the classical dichotomy?

Housing supply and demand is an example of the effects supply and demand can have on price elasticity. The most recent housing boom from 2000-2005 was not only a boom in housing prices, but also in-house construction. Based on your readings, there are a number of factors that determine housing prices. Some are based on economic theories and some are based on more intangible factors. Describe the key economic factors which effect housing prices and how they are determined (Home...

Question 1: Suppose an economy is in equilibrium. a) Using aggregate demand and aggregate supply, illustrate the equilibrium. Do not forget to include the long-run aggregate supply. b) Now suppose the central bank decided to increase the money supply in the economy. Using the theory of liquidity preference and the money market graph, illustrate what is going to happen to the aggregate demand. c) Draw the new short-run equilibrium of the economy, as a result of the shift in aggregate...

Question 2 Let’s consider the supply and demand curves for natural gas. Suppose that the supply curve is: Qs = 10+ 0.6PG + 0.05PO and the demand curve is: Qd = 0.01−2PG + 0.5PO, where Qs and Qd are the quantities supplied and demanded measured in trillion cubic feet, PG is the price of natural gas in dollars per thousand cubic feet, and PO is the price of oil in dollars per barrel. Suppose that the price of oil is...
