Government expenditures & public debt Flashcards
Debt: Definition
is a stock of what the government owes as a result of past deficits
Deficit: definition
is a flow - how much the government borrows during a given year
Inflation-adjusted deficit
the correct measure of the deficit
Deficit: calculation
Deficit = G - (Tax - TR)
G : government spending
tr : transfers
Tax : total taxes
government budget constraint with a balance budget each period (no debt)
Gt + Vt = Tt + Mt − Mt−1/Pt
real purchases + real transfers = real taxes + real revenue from money creation
If the government runs a deficit, government debt increases as …
the government borrows to fund the part of spending in excess of revenues
If the government runs a surplus, government debt decreases as…
the government uses the budget surplus to repay part of its outstanding debt
primary deficit: calculation
The difference between spending and taxes, Gt - Tt
primary surplus: calculation
Tt- Gt
The government budget constraint: money supply does not change over time
Mt −Mt−1/Pt =0 –> Gt + Vt = Tt
Budget deficit
Bt+1 − Bt = Gt + Vt+rtBt − Tt
gouvernement budget constraint :
Gt +rBt =Tt +(Bt+1 −Bt)
debt-to-GDP ratio: definition
the ratio of debt to output
The change in the debt ratio over time (the left side of the equation) is equal to the sum of two terms:
- The first term is the difference between the real interest rate and the growth rate, times the initial debt ratio
-The second term is the ratio of the primary deficit to GDP
debt-to-GDP ratio: calculation
Bt/Yt -Bt-1/Yt-1 =(r-g) Bt-1/Yt-1 +Gt -Tt/Yt
the ratio of the primary deficit to GDP is equal to zero, what does happen ?
debt increases or decreases depends on whether the interest rate is positive or not
debt-to-GDP ratio increases or decreases depending on ?
the interest rate is larger or smaller than the growth rate
increase in the ratio of debt to GDP will be larger:
- the higher the real interest rate,
- the lower the growth rate of output
- the higher the initial debt ratio
- the higher the ratio of the primary deficit to GDP
Under the Ricardian equivalence proposition
- a long sequence of deficits and the associated increase in government debt are no cause for worry
- As the government is dissaving, the argument goes, people are saving more in anticipation of the higher taxes to come.
- The decrease in public saving is offset by an equal increase in private saving. Total saving is therefore unaffected, and so is investment.
- The economy has the same capital stock today that it would have had if there had been no increase in debt. Therefore, high debt is no cause for concern
No matter when taxes will be increased, the government budget constraint still implies …
that the present value of future tax increases must always be equal to the decrease in taxes today.
future tax increases appear more distant and their timing more uncer
tain, consumers are in fact more likely
to ignore them
–> because they expect to die before tax go up or they don’t think far into the future
In the short run: larger deficits are likely to lead to?
higher demand and higher output
In the long run
higher government debt lowers capital accumulation and, as a result, lowers output
long-run adverse effects on capital accumulation
adverse effects on output, does not imply that fiscal policy should not be used to reduce output fluctuations
