This chapter explores the difference between the budget deficit and national debt, the impact of fiscal policy on the deficit, the factors that influence government budget deficits, and the effects of deficits on interest rates and GDP. It also examines the government budget constraint, the concept of crowding out, and the Ricardian theory.

Learning Objectives • What is the difference between the deficit and the debt? • What are the links between the deficit and the debt? • What are the budget constraints faced by the government? • How does fiscal policy affect the budget deficit? • How does the state of the economy affect the budget deficit? • How do we determine if a budget deficit is because of fiscal policy or the state of the economy?
Learning Objectives • When do countries run government budget deficits? • Why might a country incur a government budget deficit? • What is the crowding out effect? • When is crowding out effect of government deficits large? • What is the Ricardian theory about the effects of deficits on interest rates and real GDP? • What is the evidence on the Ricardian theory?

Key Terms • Government deficit: The difference between government outlays and revenues • Government outlays: Government outlays equal government purchases of goods and services plus transfers • Government revenues: Money that flows into the government sector from households and firms, largely through taxation, is called government revenues • Government purchases: Government purchases equals spending by the government on goods and services
Key Terms • Transfers: Transfers are cash payments from the government to individuals and firms • Examples are unemployment insurance and Medicaid payments • Government surplus: The government surplus is equal to total tax revenues collected by the governments less its purchases of goods and services and transfers to households • Government budget constraint: The government budget constraint says that the deficit must be financed by issuing government debt • Government debt: The stock of government debt is the total outstanding obligations of a government at a point in time
Key Terms • Intertemporal budget constraint: According to the government’s intertemporal budget constraint, the discounted present value of outlays, excluding interest on the debt, minus the discounted present value of taxes must equal the current stock of debt outstanding • Primary deficit: The primary deficit is the difference between government outlays excluding interest payments and government revenues • Primary surplus: The primary surplus is the negative of the primary deficit
Key Terms • Fiscal policy: Fiscal policy refers to changes in taxation and the level of government purchases, typically under the control of a country’s lawmakers • Exogenous variable: An exogenous variable is determined outside the model and is not explained in the analysis • Expansionary fiscal policy: Increases in government purchases or reductions in tax rates are called expansionary fiscal policy • Contractionary fiscal policy: Decreases in government purchases or increases in tax rates are called contractionary fiscal policy
Key Terms • Cyclically adjusted budget deficit: The cyclically adjusted budget deficit is the difference between outlays and revenues calculated under the assumption that the economy is operating at potential GDP • Potential output: Potential output is the amount of real GDP the economy produces when the labor market is in equilibrium and capital goods are not lying idle
