  4. Macroeconomic Policy • The Long-Run adjustment back to Yp may take a long time so most economists believe that the government can help expedite the return to full employment and stable prices. • Stabilization Policy: The use of government policy to reduce the severity of recessions and rein in excessively strong expansions.

  5. Macroeconomic Policy • A. Policy in the Face of Demand Shocks • Negative demand shock causes a recessionary gap. • The price level falls, but so does real GDP. • Unemployment becomes a problem • Government policy (both Fiscal and monetary) is designed to reverse this decline in AD. • This shortens the duration of a recession.

  6. Macroeconomic Policy • Positive demand shocks cause an inflationary gap. • The price level rises and so does real GDP. • Unemployment falls, but I inflation is the real problem • Again, government policy would be geared toward reversing the increase in AD • This shortens the duration of an inflationary period.

  7. Macroeconomic Policy • Responding to Supply Shocks • There is very little policy makers can do to reverse a supply shock • It is much easier to affect spending (through AD) than it is to affect production (through AS) • What if we tackled a negative supply shock by trying to influence AD?

  8. Macroeconomic Policy • Negative Supply Shocks • Suppose policy makers wanted to shift aD to the right to fight unemployment. • This would worsen the inflation. • Or suppose policy makers wanted to shift AD to the left to fight the inflation. • That would only worsen the unemployment • There are no good options here.

  9. Fiscal Policy – The Basics • A Key understanding to fiscal policy is to understand its origins. • Fiscal policy is all about taxation and government spending. • The President proposes a budget to Congress that includes plans for spending and tax collection. • Eventually Congress will amend and approve a budget and it becomes law. • This fundamentally differs from monetary policy which is created by the Federal Reserve, the central bank of the U.S.

  10. Fiscal Policy – The Basics • Taxes, Purchases of Goods and Services, Government Transfers, and Borrowing • The government plays a sizeable role in the circular flow diagram • Government Spending – Like households, the government spends money on goods and services. • What are examples of goods and services purchased by the government?

  11. Fiscal Policy – The Basics • Local: police cars in your city • State: A system of State Parks • Federal: The Military

  12. Fiscal Policy – The Basics • Transfer Payments • The government also provides transfer payments to some households. • Examples of transfer payments: • Social Security • Medicare • Medicaid • VA benefits, • Food Stamps • Etc.

  13. Fiscal Policy – The Basics • Tax Collection • Like households, the government must collect money in order to pay for this spending. • The Government Collects Taxes • What are some taxes that you or your parents pay?

  14. Fiscal Policy – The Basics • Tax Collection (cont.) • Sales tax • Income tax • Property tax • Vehicle registration tax • Gas • Excise taxes (on liquor or tobacco) • Tax on corporate profits (dividends)

  15. Fiscal Policy – The Basics • Like households, the government can borrow to make up for a shortfall in tax revenue that does not pay for all of the spending. • Government borrowing will be covered in future sections of the course.

  16. Government Budget and Total Spending • How does the government affect AD? • Remember, if we add up all of the spending in an economy we get: • C+I+G+(X-M) • G: government purchases of goods and services • This directly affects GDP and thus AD

  17. Government Budget and Total Spending • Indirectly, the government can influence consumption spending ( C) through taxes and transfers. • Look at what goes into consumption spending: • A person receives income Y from his/her job • Taxes are paid to the government and sometimes transfer payments are received by the government. • What is left over is disposable income Yd • Disposable income can now either be consumed or saved • Yd = Y – taxes = C + S or • C = Yd – S • Remember, when Yd increases, so does C

  18. Government Budget and Total Spending • So the government can indirectly increase C if it can increase Yd • How can it increase Yd? • By cutting taxes or by increasing transfer payments • The government can affect investment spending (I) through tax policy

  19. Expansionary and ContractionaryFiscal Policy • (Two short-run states of an economy – recessionary gap and an inflationary gap • Recessionary GAP - fiscal policy should try to shift AD to the right • Expansionary Fiscal Policy normally takes one of three forms: • An increase in government purchases of goods and services • A cut in taxes • An increase in government transfers

  20. Expansionary and ContractionaryFiscal Policy • Inflationary Gap – Fiscal policy should try to shift AD to the left. • Contractionary fiscal policy, normally takes one of three forms: • A decrease in government purchases of goods and services • An increase in taxes • A decrease in government transfers

  21. A Cautionary Note: Lags in Fiscal Policy • Fiscal policy looks easy but in reality it is more difficult because there are important time lags in its use. • Recognition Lag: The government has to realize that the recessionary gap exists because economic date takes time to collect and analyze, and • Recessions are often recognized only months after they have begun.

  22. A Cautionary Note: Lags in Fiscal Policy • Decision Lag: The government has to develop a spending plan, which can itself take months, particularly if politicians take time debating how the money should be spent and passing legislation. • Implementation Lag: It takes time to spend money. • For example, a road construction project begins with activities such as surveying that don’t involve spending large sums. • It may be quite some time before the big spending begins. • By this time, the economy might have already begun self-correcting back to Yp.

  23. In-Class Activities • Practice Questions: 1. The economy is currently experiencing a recessionary gap. • List two fiscal policy options that would move the economy closer to potential real GDP • Describe how your policy would achieve the desired result 2. The economy is currently at a level of output that exceeds potential GDP (Yp). • List two fiscal policy options that would move the economy closer to potential real GDP. • Describe how your policy would achieve the desired result.
