Final answer:
The real money demand in the given economy, calculated using the given formula Md/P = 500 + .2Y - 1000i and substituting P = 150, Y = 500, and i = 0.08, is 520 units of currency.
Step-by-step explanation:
To calculate the real money demand (Md/P), we use the provided money demand function Md/P = 500 + .2Y - 1000i, where P is the price level, Y is real income, and i is the nominal interest rate. Given that P = 150, Y = 500, and i = 0.08, we can plug these values into the function:
Real money demand = 500 + .2(500) - 1000(0.08) = 500 + 100 - 80 = 520.
Therefore, the real money demand in this economy is 520 units of currency.
