Aggregate Demand Curve ( AD ): It shows how price and the quantity demanded are related to each other. The curve is negatively slopped which means that when prices rise the quantity demanded falls. Fiscal policy : It includes government expenditure and taxes. When government expenditure is increased or taxes are decreased then Ad curve shifts rightward and vice versa. Monetary policy : It includes money supply changes. When money supply increases Ad curve shifts rightward and vice versa. Aggregate Supply Curve ( AS ): It shows how price and the quantity supplied are related to each other. The curve is positively slopped which means that when prices rise, the quantity supplied also rises. The curve depends on the duration of time. Short Run Aggregate Supply ( SRAS ): It is a positively slopped curve in which supply increases when price rises. The reason for upward slopping is that the wages are sticky in the short run due to formal or informal contracts. At higher aggregate prices there is higher profit leading to high level of output. Long Run Aggregate Supply ( LRAS ): It is a vertical curve which means it is independent of price. When price increases there is no change in quantity supplied. In the long run nominal wages are not fixed rather it can be negotiated. Supply Shock: In every economy it is a type of sudden event that leads to change in the supply of output for short period of time. Supply may decrease or increase depending upon the type of shock. Positive Supply Shock: It is a type of shock in which aggregate supply in an economy expands. It causes price to increase. It is a rare phenomenon. Negative Supply Shock: It is a type of shock in which aggregate supply in an economy degrades.

Concept Introduction:

Aggregate Demand Curve (AD): It shows how price and the quantity demanded are related to each other. The curve is negatively slopped which means that when prices rise the quantity demanded falls.

Fiscal policy: It includes government expenditure and taxes. When government expenditure is increased or taxes are decreased then Ad curve shifts rightward and vice versa.

Monetary policy: It includes money supply changes. When money supply increases Ad curve shifts rightward and vice versa.

Aggregate Supply Curve (AS): It shows how price and the quantity supplied are related to each other. The curve is positively slopped which means that when prices rise, the quantity supplied also rises. The curve depends on the duration of time.

Short Run Aggregate Supply (SRAS): It is a positively slopped curve in which supply increases when price rises. The reason for upward slopping is that the wages are sticky in the short run due to formal or informal contracts. At higher aggregate prices there is higher profit leading to high level of output.

Long Run Aggregate Supply (LRAS): It is a vertical curve which means it is independent of price. When price increases there is no change in quantity supplied. In the long run nominal wages are not fixed rather it can be negotiated.

Supply Shock: In every economy it is a type of sudden event that leads to change in the supply of output for short period of time. Supply may decrease or increase depending upon the type of shock.

Positive Supply Shock: It is a type of shock in which aggregate supply in an economy expands. It causes price to increase. It is a rare phenomenon.

Negative Supply Shock: It is a type of shock in which aggregate supply in an economy degrades.

6. Rent seeking The following graph shows the demand, marginal revenue, and marginal cost curves for a single-price monopolist that produces a drug that helps relieve arthritis pain. Place the grey point (star symbol) in the appropriate location on the graph to indicate the monopoly outcome such that the dashed lines reveal the profit-maximizing price and quantity of a single-price monopolist. Then, use the green rectangle (triangle symbols) to show the profits earned by the monopolist. 18 200 20 16 16 14 PRICE (Dollars per dose) 12 10 10 8 4 2 MC = ATC MR Demand 0 0 5 10 15 20 25 30 35 40 45 50 QUANTITY (Millions of doses per year) Monopoly Outcome Monopoly Profits Suppose that should the patent on this particular drug expire, the market would become perfectly competitive, with new firms immediately entering the market with essentially identical products.

Consider a call option on a stock that does not pay dividends. The stock price is $100 per share, and the risk-free interest rate is 10%. The call strike is $100 (at the money). The stock moves randomly with u=2 and d=0.5. 1. Write the system of equations to replicate the option using A shares and B bonds. 2. Solve the system of equations and determine the number of shares and the number of bonds needed to replicate the option. Show your answer with 4 decimal places (x.xxxx); do not round intermediate calculations. This is easy to do in Excel. A = B = 3. Use A shares and B bonds from the prior question to calculate the premium on the option. Again, do not round intermediate calculations and show your answer with 4 decimal places. Call premium =
