What you will learnWhat you will learnin thisin this ModuleModule::
• Why governments calculate the cyclically adjusted budget balance

• Why implicit liabilities of the government are also a cause for concern

The Budget Balance as aThe Budget Balance as a Measure of Fiscal Policy Measure of Fiscal Policy
• Sgov = T - G - Transfers
• Expansionary policies reduce budget balance
• Contractionary policies increase budget balance
• G has a greater impact than T or Transfers
• Changes in budget balance are often result, not cause, of economic fluctuations

Should the Budget Be Balanced?Should the Budget Be Balanced?
• Political motivation for running deficits or balancing the budget (deficits cater to voters)
• Economists argue against balanced budget rule in favor of cyclically balanced budget (automatic stabilizers would be compromised)
• Limits on deficits as a compromise

Deficits, Surpluses, and DebtDeficits, Surpluses, and Debt
•When spending exceeds tax revenue, government borrows (crowding out threatens investment) (increasing payment to interest threatens future budgets)
•Fiscal years
•Public Debt

Problems Posed by RisingProblems Posed by Rising Government Debt Government Debt
•Government competes with private sector for investment funds
•Financial pressure on future budgets
•Possibility of Default
•Monetizing the Debt (issuing of T-bonds)
•Cyclical budget

Monetary Policy in PracticeMonetary Policy in Practice• Fed policy and the output gap
• Taylor Rule (setting the Fed Funds Rate that takes into account both inflation rate and output gap)
• Fed Funds Rate = 1 + (1.5 x inflation rate) + (0.5 x output gap)
OR
• 1+(1.5 X π%)+(0.5 X Output Gap) Stanford Economist, John Taylor

Inflation TargetingInflation Targeting
• The Fed and Inflation (prefers inflation of about 2%)
• Inflation Targeting (used by “other” central banks—more accountability and transparency—everyone knows the goal and if the bank doesn’t succeed, it comes under scrutiny)
• Inflation Targeting v. Taylor Rule (Infl Targ more forward-looking than backward-looking as the Taylor Rule)
• Inflation Targeting v. Fed discretion
