Question

I GOT NUMBER 1. I'M CONFUSED ON HOW TO CALCULATE THE SLOPES ON #2?

Consider the table below for the supply and demand for oil in the United States.

Supply and Demand for Oil – U.S.

1.   On the grid below, create a graph depicting the market for oil using the table above, and plot the QD and the QS. (Use EXCEL to plot the graph on a separate sheet if possible, but not required. Use titles on

the graph, axes, and curves.).

2. Market curves

           

            a. Calculate the slope of the demand curve using data in the table/graph.

           

            b. Calculate the slope of the supply curve using data in the table/graph.

            c. What do the slopes of the curves indicate in this market? How does the slope of the demand curve and supply curve relate to the law of demand and the law of supply? Use 3-4 well -written sentences including numerical examples from the data given.

           

3. If the price of oil is $110 per barrel, is this above or below equilibrium, and is there a surplus or shortage in the market? How much is the surplus or shortage? Explain in one or two sentences using specific numerical calculations.

4. From your graph, explain how a change in the QUANTITY SUPPLIED could occur and give a specific scenario and include numerical examples from the data given.

5. On your graph, draw what would happen if a small INCREASE in the SUPPLY of oil occurred with a larger DECREASE in the DEMAND for oil. Explain the result using 2-3 well-written sentences and include numerical examples from your new graphical outcome including the new equilibrium of price and QD/QS compared to the old one.

Explanation / Answer

Slope of demand curve =106-104/21-22 = -2

Slope of the supply curve=106-104/13-12=2

In the equation for the demand curve P=a-bQ b is the slope of the demand curve. The slope is negative because of the inverse relationship between price and quantity demanded. As the price goes up the demand for the commodity goes down. In our table the increase in price of oil from 104 to 106, quantity demanded fell from 22 to 21. The relation between price and quantity supplied is direct, i.e an increase in the price of the commodity will lead to increase in the supply by the producer in order to earn more and more revenues. For example in our table an increase in the price of oil from 104 to 106, the quantity supplied increased from 12 units to 13 units.
