1. Note that when the chance of finding a job is 18% and the chance of separation from a job or losing it is 10%, then in equilibrium, the number of employed people who leave their jobs is equal to the unemployed people who find their jobs.
Thus, sE=fU where s= rate of job separation, f= rate of job finding,
fU=s(L-U) where employed = total labor force minus unemployed
fU=sL-sU
Now, solving for U/L which is the rate of unemployment which gives us (f+s)U=sL
U/L=s/(s+f)
Thus, the rate of unemploymnet= 10/(10+18)=10/28=0.357 or 35.7%
2. When exports are equal to $5 billion and imports are $7 billion, we have a trade deficit as imports are greater than exports. The net capital outflow will be equal to 7-5= $2 billion.
3. In a small open economy, the interest rate is determined by the world interest rate, in fact, the same as that. Because such an economy is small enough to influence world interest rates.
4. Suppose that foreign countries begin to subsidize investment by instituting an investment tax credit, then the investment demand will increase and the money will flow out of the country further leading to a rise in the interest rates.
