Monetary policy, as the name implies is related with money supply. A Monetary Policy’s purpose is to influence the economy and is conducted by the Central (Federal) bank.
Fiscal policy, as the name implies is related with tax Like the monetary policy, a Fiscal Policy’s purpose is to influence the economy as a whole and is conducted by the Government.
The Quantity Theory of Money The quantity theory formalizes the relationship between money supply and the price level: 𝑀𝑉=𝑃𝑌 Where: 𝑀= Money supply 𝑉= Velocity of circulation 𝑃= Price level 𝑌= Real output
Inflation is not quite popular, but expected inflation is much better than unexpected inflation
The Fischer Effect One of the most important relationships in macro-finance is the Fischer Effect, which links nominal interest rates to real interest rates and expected inflation. The Fischer Equation: 𝑖=𝑟+𝜋𝑒 Where: 𝑖= nominal interest rate 𝑟= real interest rate 𝜋𝑒= expected inflation
The Roles of the Central Bank The central bank is the monopoly supplier of currency. It acts as a banker to the government (and to other banks) and lender of last resort, it supervises other banks and manage the reserves of the country (Both foreign exchange and gold reserves). Finally, of course Central banks are usually responsible for conducting the monetary policy
When the central bank believes that the current growth rate of economic activity will lead to inflation, it will look to reduce money supply and increase interest rates. Such actions are known as contractionary measures, as they are meant to rein in an overheating economy.
When the central bank believes that the current level of economic growth is too slow and inflation is weakening, it will look to increase money supply and reduce interest rates. Such actions are known as expansionary measures, as they are meant to stimulate a receding economy.
1The Liquidity Trap When interest rates approach zero: People prefer liquidity (Cash) over bonds and Banks hesitate to lend (why bother if they would not realize profits) So Monetary policy loses effectiveness From the 1990s to early 2000s JAPAN was a real example of a liquidity trap. The Limits of Monetary policies Despite the theoretical power of the banking system to create money, several practical limits exist 2Risk Aversion in Banks During periods of uncertainty: Banks increases reserves, credit expansion slows and the multiplier collapses This occurred globally during the 2008 financial crisis and again during the early months of the COVID-19 pandemic.
The Fiscal policy
Money Printing to Pay Debt Risks of High Debt Result: Inflation!
Taxes in a country can be either Direct or Indirect
The Fiscal Multiplier The fiscal multiplier measures how government spending affects national income. Multiplier =1 1 − 𝑀𝑃𝐶(1 − 𝑡) Where: MPC = marginal propensity to consume t = tax rate
Example: Government increases spending by 10 B$. MPC = 0.9, t = 0.2. Result: Multiplier =1 1 − 0.9(1 − 0.2) = 3.57 Total increase in income: 10 × 3.57 =35.7𝐵$
Challenges in Executing Fiscal Policy The Fiscal policy is a powerful tool but is constrained by practical issues: 1Time Lags Recognition lag, Action (decision) lag and Impact lag 2Political Constraints Governments may prioritize political cycles over economic logic. 3Financing Constraints High debt limits fiscal space.
