Introduction to Macroeconomics

Overview of Macroeconomics

Macroeconomics is the branch of economics that studies the behavior and performance of an entire economy, rather than individual markets. It focuses on the interactions among consumers, businesses, governments, financial institutions, and central banks, such as the Bank of Canada, across all markets, including international groups.

• Gross Domestic Product (GDP): The total monetary value of all final goods and services produced within a country in a given period. GDP is a key indicator of a nation's standard of living.

• Unemployment and Inflation: Two major economic variables that significantly affect the standard of living.

Additional info: Macroeconomics also examines fiscal and monetary policy, economic growth, and business cycles.

Unemployment

Definition and Measurement

Unemployment refers to the total number of noninstitutionalized adults (aged 15 or older) who are willing and able to work, actively seeking employment, but have not found a job.

• Economic Cost: Unemployment is costly to the economy due to the loss of potential output.

Labour Force

The labour force consists of individuals aged 15 years or older who either have jobs or are actively looking and available for jobs. It is the sum of the employed and unemployed.

• Labour Force Participation Rate: The percentage of noninstitutionalized persons 15 years of age and older who are employed or seeking employment.

Unemployment Rate

The unemployment rate is the proportion of the measured labour force that is unemployed.

• Formula:

Categories of Unemployed Individuals

• Job Loser: An individual whose employment was involuntarily terminated or who was laid off.

• Re-entrant: An individual who previously left the labour force and has now re-entered it looking for a job.

• Job Leaver: An individual who quits voluntarily.

• New Entrant: An individual who has never held a full-time job lasting two weeks or longer but is now seeking employment.

Discouraged Workers

• Discouraged Workers: Individuals who have stopped looking for a job because they believe they will not find a suitable one.

Types of Unemployment

There are four major types of unemployment, each with distinct causes and implications:

• Frictional Unemployment: Caused by workers searching for appropriate job offers. This is temporary and part of normal labour market turnover.

• Cyclical Unemployment: Results from contractions or recessions in economic activity.

• Structural Unemployment: Occurs when there is a mismatch between workers' skills and job requirements, often due to technological change or shifts in the economy.

• Seasonal Unemployment: Varies with the time of year and is related to jobs that are only available during certain seasons.

Full Employment and Natural Rate of Unemployment

• Full Employment: An arbitrary level of unemployment that corresponds to “normal” friction in the labour market, with no cyclical unemployment.

• Natural Rate of Unemployment: The rate of unemployment that is estimated to prevail in the long-run macroeconomic equilibrium, including only frictional and structural unemployment.

Unemployment Trends in Canada

Unemployment rates in Canada have fluctuated over the past century, with notable peaks during the Great Depression, recessions, and the COVID-19 pandemic.

Additional info: Unemployment rates tend to rise during economic downturns and fall during periods of expansion.

Inflation and Deflation

Definitions

• Inflation: A sustained increase in the average of all prices of goods and services in an economy.

• Deflation: A sustained decrease in the average of all prices of goods and services in an economy.

Purchasing Power

• Purchasing Power: The value of money for buying goods and services. If prices rise and income remains the same, purchasing power falls.

Nominal vs. Real Values

• Nominal Value: Price expressed in today's dollars.

• Real Value: Value expressed in purchasing power, adjusted for inflation.

Measuring Inflation

• Market Basket: A representative bundle of goods and services used to track price changes over time.

• Base Year: The point of reference for comparison of prices in other years.

• Price Index: The cost of today’s market basket of goods, expressed as a percentage of the cost of the same market basket during a base year.

Major Price Indexes

• Consumer Price Index (CPI): Measures the weighted average of prices of a specified set of goods and services purchased by wage earners in urban areas.

• Industrial Product Price Index (IPPI): Tracks changes in prices for industrial products.

• GDP Deflator: Measures the change in prices of all goods and services included in GDP.

• Personal Consumption Expenditure (PCE) Index: Measures changes in the prices of goods and services consumed by households.

Example: Adjusting for Inflation

In 1977, a new house in Toronto cost $64,599. In 2022, the average price was $1,126,568, suggesting a 17.5x increase. However, after adjusting for inflation (using 2012 dollars), the 1977 price was $233,834, making the real increase only 3.7x.

• Key Point: Media reports often exaggerate price increases by ignoring inflation adjustments.

Anticipated vs. Unanticipated Inflation

Types of Inflation

• Anticipated Inflation: The inflation rate that is expected to occur.

• Unanticipated Inflation: Inflation at a rate that comes as a surprise.

Effects on Interest Rates

• Nominal Rate of Interest: The market rate of interest, expressed in today's dollars.

• Real Rate of Interest: The nominal rate of interest minus the anticipated rate of inflation.

Winners and Losers from Inflation

• Creditors: Lose from unanticipated inflation, as the real value of repayments falls.

• Debtors: Gain from unanticipated inflation, as they repay loans with money that has less purchasing power.

Protecting Against Inflation

• Cost-of-Living Adjustments (COLAs): Clauses in contracts that allow for increases in specified nominal values to account for changes in the cost of living.

• Menu Costs: The resource cost associated with recalculating prices and printing new price lists when there is inflation.

GDP, Inflation, and Unemployment: Business Fluctuations

Business Fluctuations

Business fluctuations refer to the ups and downs in business activity throughout the economy.

• Expansion: A period in which the pace of national economic activity is increasing.

• Contraction: A period in which the pace of national economic activity is decreasing.

• Recession: A period during which the rate of growth of business activity is consistently less than its long-term trend or is negative.

• Depression: An extremely severe recession.

Leading Indicators

• Reduction in the average workweek

• Increase in employment insurance claims

• Decrease in prices of raw materials

• Drop in the quantity of money in circulation

Example: COVID-19 Pandemic and Employment

During the COVID-19 pandemic, young men and women not in school full-time saw their employment rates drop by 8 percentage points, while older workers experienced a smaller 4-point decline.

• Key Point: Youth were hit harder by the pandemic due to their higher representation in sectors most affected by lockdowns and economic disruptions.

Conclusion

Understanding GDP, unemployment, and inflation is essential for analyzing the health and performance of an economy. These concepts are interconnected and influence policy decisions, business cycles, and the standard of living for individuals and society as a whole.
