The Economics in Practice states that the capital value of Professor Serebryakov’s estate is not the value for which he could sell the estate if the interest rate on “suitable” securities is higher than the average yield from the estate.  What would happen to:
a. the value of the estate if the interest rate on “suitable” securities rose?
b. the value of the estate if investment in the estate was suddenly viewed as being less risky than investment in the securities?
c. the yield on the securities if the securities were suddenly viewed as being more risky than was previously thought?
