Summary and Exam Tips for Government Debt
Government Debt is a subtopic of Macroeconomics, which falls under the subject Economics in the IB DP curriculum. A government budget is a financial plan detailing revenues and expenditures over a specific period, typically a year. It can result in a balanced budget (revenue equals expenditures), a budget surplus (revenue exceeds expenditures), or a budget deficit (revenue is less than expenditures). Governments often incur budget deficits due to high expenditure commitments, especially during recessions, necessitating borrowing through government bonds or direct loans from financial institutions.
Government debt accumulates when budget deficits exceed surpluses over time. It is commonly expressed as a percentage of GDP, known as the debt-to-GDP ratio. For instance, Japan's debt-to-GDP ratio in 2019 was 200%. High government debt can lead to increased debt-servicing costs, poor credit ratings, and impacts on future taxation and government spending. It may also result in lower private investment, increased income inequality, and the risk of a debt trap, where new loans are needed to pay off existing debt.
