Study Notes

Macroeconomics Lecture 1

Macroeconomics studies the aggregate behavior and performance of an economy.
It looks at the economic performance of countries and regions.
Most macroeconomic theories have microeconomic foundations.
Economic agents include consumers, producers, government, banks, and foreign countries.
Markets include goods markets, labor markets, money markets, and financial markets.

Objectives

Learn macroeconomic terminology (e.g., GDP, government deficit, monetary policy).
Analyze macroeconomic questions using models (e.g., how does an increase in the interest rate affect output?).
Interpret economic data (e.g., yearly GDP data across the world).
Understand current macroeconomic issues.

Practical Information: Course Material

All practical course information (grading, exams, schedules) is available on Canvas.
Textbook: Burda & Wyplosz, Macroeconomics, 7th or 8th edition, Oxford University Press (2012).
Lecture slides are posted weekly on Canvas under "Modules/Week."

Practical Information: Exams

Midterm exam (30% of final grade): open questions (fill in blanks, definitions, simple calculations).
Final exam (70% of final grade): multiple-choice questions (4 possible answers each).
Resit exam is available in July (midterm result still valid).

Roadmap

What is Macroeconomics?
Macroeconomic Accounts

What is Macroeconomics?

Microeconomics studies individual behavior.
Macroeconomics (Greek makro = "big") studies the aggregate behavior and performance of an economy.

Questions Addressed by Macroeconomics

Why do some countries grow faster than others? (economic growth, long-run)
Why do economic activities expand in some years and contract in others? (business cycle, short-run)
What causes unemployment?
What causes prices to change? (inflation)
What can the government do to promote rapid growth in income, stable prices, and high employment? (monetary and fiscal policies)
How does being part of a global economic system affect production, employment, and prices?

How to Measure Aggregate Economic Performance

Gross Domestic Product (GDP) is a key indicator of aggregate economic activity.
GDP Definition: The total value of all final goods and services produced within a specific period (per year/quarter) in a specific area (country/region).

GDP = Well-being?

GDP measures a country's economic activity, but it's not a perfect measure of well-being.
GDP doesn't capture income inequality, gender equality, human rights, environmental protection, and other factors.
Although GDP is often highly correlated with well-being, it is readily available and comparable across countries and time

GDP Variations Across Countries and Time

Real GDP per capita, adjusted for inflation (2011 prices), allows for cross-country comparisons.
Historical GDP data shows significant variation across countries and time.

Long Run vs. Short Run Economic Performance

Long run (trend) refers to the economy's behavior over decades.
Economic growth measures the rate of increase in real output over time.
Short run (business cycles) involves shorter-term fluctuations around the long-run trend.
Business cycles include booms and recessions.

Business Cycles: Deviations From Trend

Recessions are periods of decline from peak to trough.
Booms are periods of expansion from trough to peak.

Economic Growth

GDP growth rate: represents the change in GDP between two periods, using the formula (Yt / Yt-1) - 1
GDP growth can be calculated using logarithmic scale, giving a more accurate approximation for small changes( In Yt - ln Yt-1 = ln (1+ gr. ratet ) ≈ gr. rate)

Long-run Output Growth

Average growth rate over a period of time (In YT - In Yt) / (T - t) * 100

Short-Run Output Gap

Short-run output deviation from the trend.
% difference between current and trend output ( (In Yt - In Y trend,t) * 100)

Flow vs. Stock Variables

Flow: quantity measured over a time unit.
Stock: quantity measured at a point in time.
GDP is a flow variable (measured over time).

Three Definitions of GDP

Expenditure approach: Sum of all final sales within a defined geographical area (country or region).
Production approach: Sum of value added in each stage of production within a specific location (country or region).
Income approach: Sum of all incomes earned in a country (by residents and non-residents).

Definitions of GDP (1/3)

Expenditure approach: GDP is the sum of final spending within a specified region (country, region, EU etc).
Excludes intermediate sales and used goods to avoid double counting

Definitions of GDP (2/3)

Production approach: GDP is the sum of value added at each production stage within a specified region

Definitions of GDP (3/3)

Income approach: GDP is the sum of all incomes earned within a specified region

Which Economic Activities are Not Included in GDP?

GDP excludes home production (leisure, childcare, cooking) and the shadow/underground economy (activities not reported to avoid taxes or for illegal reasons).

Missing in GDP: The "Shadow" Economy

Data on hidden/shadow economy as a percentage of GDP for various countries.

The Nuances of Different GDPs

Total GDP: captures both per-person growth and population growth.
Real GDP: captures growth in output volume, adjusting for price changes over time.
Nominal GDP: captures growth in output volume, but doesn't adjust for price changes.
GDP per capita: captures growth in output per person.

GDP: Prices & Quantities

GDP considers both output quantities and prices.
Important to separate quantity and price effects when analyzing GDP changes.

Nominal vs. Real GDP

Nominal GDP uses current market prices.
Real GDP uses constant base year prices to remove the effect of price changes.

Nominal vs. Real GDP: An Example

Illustrates calculation of real GDP and nominal GDP using respective formulas

Nominal vs. Real GDP: US (2000Q1-2010Q1)

Graphical representation of nominal vs real GDP

Measurements of Price Changes

GDP deflator
Consumer Price Index (CPI)

GDP Deflator

A measure of the price level for an economy's output of goods and services.
GDP Deflator _t = ( NominalGDP_t ) / ( RealGDP_t )
Average prices of final goods weighted by their share in GDP.

GDP Deflator: An Example

Demonstrates the calculation of inflation, nominal and real GDP growth.

Consumer Price Index (CPI)

Measures a weighted average of prices of goods and services that consumers buy.
Reflects spending of a typical household, weighted according to their share in household spending.

CPI vs GDP Deflator

CPI measures prices of goods and services consumed by consumers (includes imported goods but not exports) .
GDP deflator measures prices of goods and services produced domestically (includes exports, but not imports).

CPI vs GDP deflator: The Netherlands (1960 - 2022)

Comparison of CPI and GDP deflator for the Netherlands over time

Gross National Income (GNI)

Considers an economy's economic activity attributable to its residents, regardless of where the activity occurs.
GNI = GDP + balance on primary international income

Gross Disposable National Income (GDNI)

GNI + balance on secondary international income.

A Key Accounting Identity

(S - I) + (T - G) = (X - Z)
Equation for the accounting identity that relates various macroeconomic indicators. (T - G) represents the government budget surplus or deficit; (X - Z) represents the balance of trade or net exports; (S - I) represents the balance of saving and investment in the private sector.

Interpreting the Key Accounting Identity

Implications of the identity on the relationships between private sector savings and investment, government surpluses and deficits, and the balance of trade or net exports.
