Long Run Implications of Fiscal Policy: Deficits and the Public Debt - Section 6, Module 30

  • Budget balance = the difference between the government’s tax revenue and spending [on goods and services and on govt transfers]

    • B = T - G - TR (tax revenue — government purchases of goods and services — govt transfers)

    • budget surplus = (+) and budget deficit = (-)

    • expansionary fiscal policies decrease the budget balance and contractionary fiscal policies increase the budget balance

  • changes in the budget balance can be used to assess whether a policy is expansionary or contractionary

    • can be misleading bc:

      • 2 diff changes in fiscal policy can have the same effect on the budget balance but diff effects on the economy

      • changes in budget balance are often the result (not cause) of fluctuations of the economy

  • strong relationship btwn budget balance and business cycle

    • budget moves into deficit when economy goes into recession and vice versa

      • relationship is even clearer when the unemployment rate is compared with the budget deficit as a percent of GDP (direct relationship)

      • the relationship is not solid proof that policy makers engage in discretionary fiscal policy bc the relationship is generally caused by automatic stabilizers

  • important to separate movements in the budget balance due to business cycle with movements due to discretionary fiscal policy changes

    • automatic stablizers vs deliberate changes in govt purchases/transfers/taxes

    • business cycle effects on budget balance are temporary bc in the long run, recessionary/expansionary gaps are eliminated

    • the govts tax and spending policies need to yield enough revenue in the long run to fund its spending

    • cyclically adjusted budget balance - an estimate of what the budget balance would be if real GDP = LRAS [potential output] → separates the effect of the business cycle from other effects

      • budget balance if there were no recessionary or inflationary gap

        • takes into account the tax revenue/transfers the govt would collect/save if the recessionary gap was eliminated or the revenue the govt would lose/transfer it would make if the inflationary gap was eliminated

  • budget defecitis can cause issues, but politicians are tempted to run deficits bc then they can increase spending without increasing taxes

    • however, forcing a balanced budget every year is also bad - govt should run in deficit for a few years, then surplus and cancel out

  • govt debt - accumulation of past budget deficitis minus past budget surpluses

    • continuous govt borrowing leads to crowding out:

    • todays deficits places financial pressure on future budgets

      • bc of interest

      • to pay off suhc large amounts of interest, govt either has to incr taxes, spend less, or borrow more to cover the gap

        • but by borrowing, the debt increase more

        • eventually lenders will lose faith in the govt to repay - no more funds fro the govt to borrow

        • govt will defualt on its debt - stop paying what it owes 💀💀💀💀

        • and govt cant j print more money to cover debt = inflation

      • govts should offset deficits through surpluses

  • debt-gdp ratio - the govts debt as a % of their GDP

    • if the govts debt grows slower than the gdp, the burden of oaying the debt is decr compared to potential tax revenue

    • modern govts can run deficits for a whild bc if their econ grows, it cancels out

    • debt-gdp ratio can fall even as debt is incr

  • implicit liabilities = spending promises mad eby govts that are basically a debt even tho they are NOT INCLUDING IN DEBT STATISTICS

    • largers ILs of US are from transfer paymesnt - SS[n] anad medicare and medicaid

    • govt has promosed to provide transfer payments to the benefiiciaresi - so future debt

    • dedicated taxes = expenses are paid out of special taxes on wages - pay for medicare and ss[n]

      • some is technically counted in debt statistics social security trust fund - surplus in the ss system bc ss has been taking up more revenue than needed immediately (to prepare for the future)

        • the money is held in the form of govt bonds which IS counted in total debt
