Question #58491

After carefully reading all the available information, prepare a two page (double-spaced) essay and answer the following questions:

Assume that we have the following data:

C=100+0.50Y

Ip=100-20r

Mt=0.10Y

Ms=100-10r

M=80

a. Build the IS-LM function.

b. If we assume an increase in Investments by 100 units, calculate again the IS-LM functions.

c. The intersection of IS-LM functions defines four areas. Analyze the behavior of the markets for goods and money for each area.

Expert's answer

C=100+0.50Y, Ip=100-20r, Mt=0.10Y, Ms=100-10r, M=80.

a. The IS–LM functions show the relationship between interest rates and real output, in the goods and services market and the money market.

The IS curve is defined by the equation Y = C + I + G + NX, so Y = 100 + 0.5Y + 100 - 20r - 80, Y = 240 - 40r. The LM curve is defined by the equation Mt = Ms, so 100 - 10r = 0.1Y, Y = 1000 - 100r.

b. If we assume an increase in Investments by 100 units, then the IS function will shift to the right.

c. The intersection of IS-LM functions defines four areas, and the behavior of the markets for goods and money for each area will change.
