Macroeconomics and Economic Policy

Macroeconomics

The Economy as a Whole

Macroeconomics is influenced by external market shocks, internal factors, and state intervention. These factors impact supply and demand.

Aggregate Demand

Aggregate demand (AD) is the total expenditure in an economy at a given price level. It includes spending by households, businesses, the public sector, and foreign entities. The formula for AD mirrors that of GDP: AD = C + I + G + (X-M).

Factors Affecting Demand:

  • Income Level
  • Money Supply
  • Taxes

Aggregate Supply

Aggregate supply (AS) is the total amount of goods and services that firms are willing to produce and sell at a given average price level and production cost.

Factors Affecting Supply:

  • Average Price Level: Lower prices typically lead to lower profits and reduced production.
  • Business Expectations: Positive market expectations encourage increased production, while uncertainty can hinder it.

Consumption

Household expenditure on goods and services can be categorized as:

  • Durable Goods
  • Perishable Goods
  • Services (e.g., healthcare, education)

Factors Affecting Consumption

Disposable Income: Higher disposable income leads to increased consumption.

Permanent Income: The perceived long-term average income level influences consumption patterns.

Life Cycle Hypothesis: Individuals save to maintain a consistent level of consumption throughout their lives.

Wealth: Accumulated savings and assets provide additional income and influence consumption.

Investing

Investing involves purchasing capital goods that indirectly contribute to the production of other goods. Business investment plays a crucial role in the economy.

Impact of Investment:

  • Increased Demand: Investment leads to increased production and employment, boosting demand.
  • Increased Production Capacity: Capital goods accumulation enhances a country’s production potential.

Factors Affecting Investment

Revenue: Businesses invest to generate additional income.

Costs: Investment decisions are influenced by interest rates on borrowings and taxes.

Capacity Utilization: High capacity utilization and increasing demand encourage further investment.

Future Expectations: Positive economic indicators and stability promote investment.

The Investment Multiplier

The investment multiplier measures the overall increase in spending throughout the economy resulting from an increase in investment. It is related to the marginal propensity to consume (MPC), which represents the proportion of additional income that people spend on goods and services.

Saving

Saving is the portion of disposable income that is not consumed. It is essential for business investment.

Reasons for Saving:

  • Future well-being
  • Asset accumulation
  • Retirement planning
  • Contingency planning

Marginal Propensity to Save (MPS): The MPS is the proportion of additional income that people save.

Economic Cycle Phases:

  • Depression/Trough: The lowest point of a recession, characterized by underutilized resources and high unemployment.
  • Expansion/Recovery: A period of economic growth.
  • Boom/Peak: The highest point of expansion, where production capacity is fully utilized.

Economic Policy

Economic policy refers to government interventions aimed at achieving specific economic goals.

Objectives of Economic Policy

Sustainable Economic Growth: Increasing the production of goods and services over time to improve citizen welfare, measured by GDP and disposable income.

Full Employment: Utilizing all resources efficiently, with a target employment rate around 90%.

Price Stability: Controlling inflation and maintaining the purchasing power of consumers, measured by the Consumer Price Index (CPI).

Types of Economic Policy

Fiscal Policy: Government actions involving taxes and public spending to influence economic activity.

Monetary Policy: Actions taken by the central bank to control inflation and maintain price stability by managing the money supply and interest rates.

Foreign Policy: Government intervention in regulating imports, exports, and exchange rates.

Income Policy: Measures to control inflation by influencing wages and prices.

Fiscal Policy

Fiscal policy involves government revenue (taxes) and expenditure to achieve economic objectives.

Types of Fiscal Policy

Discretionary Instruments: Active policy changes implemented by the government, such as public works programs, employment and training plans, transfer programs, and tax rate modifications.

Automatic Stabilizers: Built-in mechanisms that automatically adjust government revenue and expenditure in response to economic fluctuations, such as proportional taxes, social security contributions, and unemployment benefits.

General State Budget (PGE)

The PGE details the government’s planned revenue and expenditure for a given year.

Expenditure

Current Expenditure: Costs of providing public services like healthcare, education, and justice.

Investment Expenditure: Spending on infrastructure and maintaining productive capacity.

Transfers and Subsidies: Payments to individuals and businesses, such as pensions, scholarships, and job creation incentives.

Revenue

Social Security Contributions: Payments made by workers and employers.

Taxes: Compulsory contributions to the government, including direct taxes (e.g., income tax) and indirect taxes (e.g., VAT).

Fees: Payments for the use of public services.

Other Income: Includes transfers (e.g., lottery), property income, asset sales, and capital transfers from the EU.

Budget Balance

  • Balanced Budget: Revenue equals expenditure.
  • Surplus: Revenue exceeds expenditure.
  • Deficit: Revenue is less than expenditure.

Managing Budget Deficits:

  • Issuing public debt
  • Raising taxes
  • Increasing the money supply

Monetary Policy

Monetary policy involves actions by the central bank to achieve its objectives, primarily price stability, by managing the money supply and interest rates.

Money

Money serves as a medium of exchange.

Types of Money

Legal Tender: Banknotes and coins issued by the monetary authority.

Bank Money: Deposits held in various accounts, including current accounts.

Time Deposits: Deposits held for a specific period with agreed-upon interest.

Other Assets: Treasury bills and other securities.

The money supply is the total amount of money circulating in an economy.

Banks and Money Creation

Banks operate by accepting deposits and lending a portion of those funds, while reserving a fraction (fractional reserve) to meet withdrawals. This process leads to the creation of money.

Money Multiplier

The money multiplier describes the expansion of the money supply resulting from an initial deposit. It is inversely related to the reserve requirement.

Types of Monetary Policy

Reserve Requirements: Mandating a minimum reserve ratio for financial institutions.

Open Market Operations: The central bank buying or selling government securities to influence the money supply and interest rates.

Financial System

The financial system comprises intermediaries that channel savings into financing consumption, investment, and public spending.

Financial Intermediaries in Spain

Bank Financial Intermediaries:

  • Bank of Spain
  • Commercial Banks
  • Savings Banks
  • Credit Unions

Non-Bank Financial Intermediaries:

  • ICO (Official Credit Institute)
  • Insurance Companies

The Stock Market

Stock markets facilitate the trading of securities in a competitive and orderly manner.

Types of Securities

Bonds: Debt instruments with fixed interest payments.

Stocks: Ownership shares in a company, with potential dividend payments.
