Part 1) An increase in the government deficit decreases the price of securities. This is because increase in government deficit means that government has increased its expenditure. Increase in government expenditure raises the level of income in the economy. For a given level of money supply, an increase in the level of income raises the transaction demand for money in the economy. People will now start to withdraw money from their speculative balances to finance their transaction needs. To keep the money market in equilibrium the interest rate will rise while the price of securities will decline.
As shown in the diagram below the increase in government expenditure causes the IS curve to shift from IS1 to IS2. The interest rate rises along the LM curve to keep the money market in equilibrium from r1 to r2.
Part 2) A decrease in the money supply will cause the price of securities to decline. This is because, for a given level of income, a decrease in the level of money supply raises the transaction demand for money in the economy. People will now start to withdraw money from their speculative balances to finance their transaction needs. To keep the money market in equilibrium the interest rate will rise while the price of securities will decline.
As shown in the diagram below decrease in money supply causes the LM curve to shift from LM1 to LM2. The interest rate rises along the LM curve to keep the money market in equilibrium from r1 to r2.
