This is a problem on page 164 of SchweserNotes book2 Economics.
Problem 11. If money supply and demand are in equilibrium and the central bank sells securities in the open market:
A. bank reserves will increase;
B. short-term interest rates will derease;
C. firms and households will sell securities for cash.
Could anyone explain why the correct answer is the correct answer? Think about this problem by yourself then I will give you my reasoning in the next post.
I think C is correct,Becouse central banks sells securities ,means tighten policy in short term,makes money supply curve left shift,push the short -term interest rate upward,the market investor (like firms and households) can expect a decline in securities' price,so they choose to hold cash rather than securities
