Macroeconomic Fundamentals: Markets, Inflation, and Employment

The Functioning of the Economy

Internal and External Market Forces

• Internal Forces: Factors originating within the economy.
• External Shocks: Events occurring outside the economy that impact its performance.
• Macroeconomic Policy: Government interventions to manage economic variables.

Macroeconomic Objectives

• Economic Growth: Increasing production and overall welfare.
• Inflation: The sustained rise in price levels.
• Employment: Maximizing labor participation.
• Public Deficit: Managing government spending and revenue.
• Interest Rates and Exchange Rates: Monetary stability indicators.

Aggregate Demand and Aggregate Supply

Definitions

• Aggregate Demand: The total quantity of goods and services that operators are willing to purchase within a specific timeframe.
• Aggregate Supply: The total quantity of goods and services that producers are willing to supply at every price level within a specific timeframe.

Inflation in Aggregate Models

Inflation represents an increase in the general price level:

• Demand-Pull Inflation: Caused by a rightward shift in the aggregate demand curve. Effects include increased inflation and economic growth.
• Cost-Push Inflation: Caused by perturbations in production costs (e.g., oil prices, wages).

Unemployment

Measurement

• Definition: Individuals belonging to the active population who are eligible to work, seeking employment, but unable to find it.
• IMEN: Monthly data based on registered unemployment office records.
• EPA: Quarterly statistics providing a broader view of the labor market.

Types of Unemployment

• Cyclical: Depends on economic fluctuations.
• Seasonal: Occurs during specific times of the year.
• Frictional: A natural consequence of market dynamics.
• Structural: Mismatch between professional skills and market requirements.

Effects of Unemployment

• Social: Negative psychological impacts and discrimination.
• Economic: Loss of productivity and output.

Explanatory Theories of Unemployment

• Classical Theory (Monetary): Attributes unemployment to labor market rigidities and inadequate policies.
• Keynesian Theory: Argues that unemployment is involuntary and caused by insufficient aggregate demand.

Causes of Unemployment

• Population Growth: Increases the labor supply.
• Technological Progress: Automation replacing human labor.
• Economic Cycles: Periodic fluctuations in labor demand.

The Economic Cycle

Fluctuations in GDP around the long-term production trend.

Components

• Trend: Long-term growth path.
• Seasonal Variations: Fluctuations occurring in less than one year.
• Random Variations: Unpredictable fluctuations.

Phases

• Expansion: Production is increasing.
• Peak: Maximum production reached, often with rigidity in productive factors.
• Recession: Decline in production and corporate profits.
