Government Budget: Balance, Deficit and Surplus – Comprehensive Notes

Key Definitions

Budget Surplus
- Occurs when government revenues > expenditures.
Budget Deficit
- Occurs when government expenditures > revenues.
Balanced Budget (Keynesian view)
- Balance should be achieved over the business cycle, not necessarily each year.
- Allows deficits in recessions and surpluses in booms so that, on average, \text{Revenue} = \text{Expenditure}.
Flows vs. Stocks
- Surplus/deficit – flow variables (measured over a period).
- Debt – stock variable (measured at a point in time), equal to the cumulative past deficits minus past surpluses.

Budget coverage matters
- On-budget vs. off-budget items (e.g., US Social Security) give different pictures.
- A complete measure must include every revenue and expenditure stream.
Capital vs. Current Spending
- Assets and liabilities should be incorporated; omitting tangible assets can mislead.
Nominal vs. Real Measures
- Economists scale deficits/surpluses to GDP to account for economic growth.
- Real values are inflation-adjusted; inflation reduces the real burden of a fixed nominal debt.
- Example: 2012 Malaysia deficit =\text{RM }42\text{ billion}; 10 % inflation makes real repayment 10 % cheaper.

Government’s alternate revenue source after taxation is borrowing.
Debt rises with deficits and falls with surpluses.
Question “How big is big?” depends on which assets/liabilities are counted and who holds the debt (central bank, states, local governments, foreigners).
Inflation can act as a hidden revenue source by eroding the real value of nominal debt ("inflation tax").
- Example: Borrow RM 10 billion; price level up 8 % → real repayment RM 9.2 billion.

Fiscal-Deficit-to-GDP Ratio (2014-2022)
- Ranged roughly from -2.9\% to -6.4\%; spike in 2020–21 due to the pandemic.
Federal Debt-to-GDP (2017-2023)
- Rose from 52.4\% (2017) to 64.3\% (2020), dipped, then reached highest ratio in 2023.
Domestic Debt-to-GDP (2017-2023)
- Climb from 48.5\% to 62.7\%.
External Debt (RM billion)
- RM 64.9 b (2005) → RM 133.8 b (2010) → RM 210.8 b (2014) → RM 272.45 b (2023).

Raises interest rates, crowds out private saving & investment → slower growth.
Ricardian Equivalence Offset: if people foresee higher future taxes, they save more now, mitigating interest-rate rise.
Debt-financed spending can raise GDP, spur private investment during recessions (counter-cyclical boost).
But may instead fuel consumption (e.g., US 1970s–80s) when private saving lags.

Future generations should repay debts that financed long-lived public capital (schools, bridges, hospitals) because they enjoy the benefits once projects are complete.

Debt finance is justified where beneficiaries are future residents, especially given population mobility.
Options: “Pay-as-you-go” (current tax) vs. “Tax when benefits accrue.”

National governments issuing debt in their own currency can, as last resort, print money → perceived risk-free.
Eurozone sovereigns lacked monetary autonomy during the euro crisis; default risk higher.
Private debt usually holds greater default risk than sovereign debt.

Internal Debt (owed to citizens)
- No real burden on future generations; repayment redistributes income internally (“right hand owes left hand”).
- Modern caveat: internal debt security questioned if distributional/inequality effects matter.
External Debt (owed abroad)
- If spent on current consumption → future generations’ consumption falls.
- If used for capital projects → outcome depends on comparison \text{Marginal Return} vs. \text{Marginal Cost}.
- If MR < MC, future generations bear a net burden.

Multiple cohorts coexist; debt can transfer resources from young to old.
Regardless of financing method, government borrowing tends to shift consumption toward the older cohort, imposing implicit taxes on the young.

Theory (Ricardo, revived by Barro): deficits neither change aggregate demand nor interest rates because households save extra to cover expected future taxes.
Requires strict assumptions:
- Perfect capital markets; no liquidity constraints.
- Operative intergenerational altruism.
Empirical challenges: 1980s US deficits coincided with falling private saving, contradicting strict equivalence.

With a surplus, government repays debt → shifts supply of loanable funds right.
Lower interest rates encourage more private investment (ideal use vs. tax cuts that stoke consumption).

Aim: stabilize output, employment, prices.
Automatic stabilizers – built-in tax/expenditure rules that soften cycles.
Discretionary policy – active changes to G or T when automatic tools insufficient.
Timing Lags Problem
- Recognition lag, decision lag, implementation lag, impact lag.
- Policy may kick in after economy has shifted, exaggerating swings (illustrated by points A → D → F′, G′).

Moderate debt can aid growth; excessive debt risks fiscal crises (Reinhart, Reinhart & Rogoff, 2012).
Necessitates disciplined budgeting: clear spending & revenue targets; credible fiscal rules.

Positive vs. normative public-finance analysis.
Externalities, public goods, political process, expenditure programs, financing, budgeting.
Empirical focus: ASEAN fiscal sustainability studies.

Intergenerational equity: fair sharing of costs/benefits across time.
Transparency in off-budget items to preserve democratic accountability.
Monetary sovereignty vs. currency-union constraints influences default probability.
