Astandard "money demand" function used by macroeconomists has the form ln( ) = + ln( ) + m β , 0 β1 gdp β2r where m is the quantity of (real) money, gdp is the value of (real) gross domestic product, and r is the value of the nominal interest rate measured in percent per year. supposed that = and = . β1 2.34 β2 − 0.06 what is the expected change in m if gdp increases by %? 5 the value of m is expected to (1) by approximately %. (round your response to the nearest integer ) what is the expected change in m if the interest rate increases from % to %? 3 9 the value of m is expected to (2) by approximately %

1.The money demand will rise by 1.154%

2. The money demanded will fall and for a 1% increase in interest , the money demanded will fall by 0.38%

Explanation:

1. Money demand function

ln(m) = β0 +β1 ln(GDP)+β2R

Suppose β1 = 1.5 , β2 = −0.04 , GDP = $ 100 & R = 3%

ln(m) = 1.5 ln ($100) - 0.04 X 0.03

ln(m) = 6.91

m = 1002.247

Suppose the GDP increases by 1%; the new GDP will be = $ 101  

ln(m) = 1.5 ln ($101) - 0.04 X 0.03

ln(m) = 6.92

m = 1013.81

If the GDP increases by 1% ,the money demand will rise by 1.154%

2.

If the interest rate increases from 3% to 4%

ln(m) = 1.5 ln ($100) - 0.04 X 0.04  

ln(m) = 6.906155

m = $ 998.400

If the interest rate rises from 3% to 4% , the money demanded will fall and for a 1% increase in interest , the money demanded will fall by 0.38%

answer: in the short-run firms will respond by raising the price of turkey.

explanation: initially the long-run equilibrium is at a price of $5 per pound of turkey and a quantity of 50 million pounds per year. now, when webmd claims that a protein found in turkey will increase your expected lifespan by 4 years. the consumers demand for turkey will increase at every price shifting the demand curve to the right from d1 to d2. while, there will be no change in the supply curve in the short-run as it is not possible for producers to adjust supply so quickly. as a result the new equilibrium will occur at a higher price and a higher quantity of turkey.

thus, in the short run firms will respond by increasing the price of turkey, selling more quantity at a higher price and earning economic profits.
