Economic Indicators and Business Cycles: Free Course

About this course

Economic indicators summarize different aspects of an economy. This course explains how output, prices, unemployment and business-cycle movements are measured and interpreted. Study the complete public source playlist from Khan Academy in English, with all 22 recordings available in the on-site classroom. Lessons retain their original titles and source order, including worked examples, introductions and repeated entries.

Course Overview

GDP is developed through income, expenditure and value-added perspectives, with examples distinguishing final output from intermediate contributions. Nominal and real GDP, together with the GDP deflator, separate changes in prices from changes in measured production. The inflation lessons add consumer-price calculations and consider who may be affected differently by inflation or deflation. Unemployment examples distinguish frictional, structural and cyclical components and work through rate calculations. Business-cycle lessons connect fluctuations with aggregate activity and production possibilities. The source also addresses limitations of GDP, so a higher output measure should not be treated as a complete statement about welfare. The repeated business-cycle video remains included as the playlist supplies it. Check the denominator, base period and units behind each indicator before comparing values.

How to study the course

• Videos 1–5: this part of the source list includes “Value added approach to calculating GDP” through “Deflation”. List the assumptions of the model. Keep a brief working note, revisit an unclear explanation and test one example before moving to another part of the material.
• Videos 6–11: this part of the source list includes “Circular flow of income and expenditures” through “Natural, cyclical, structural, and frictional unemployment rates”. Identify the participants and incentives. Keep a brief working note, revisit an unclear explanation and test one example before moving to another part of the material.
• Videos 12–16: this part of the source list includes “Income and expenditure views of GDP” through “Parsing gross domestic product”. Compare outcomes after one defined change. Keep a brief working note, revisit an unclear explanation and test one example before moving to another part of the material.
• Videos 17–22: this part of the source list includes “Investment and consumption” through “Business cycles and the production possibilities curve”. Explain a mechanism before making a conclusion. Keep a brief working note, revisit an unclear explanation and test one example before moving to another part of the material.

Who is this for?

This course suits students and interested readers studying the named economic concepts. It also provides a recorded reference for revisiting a topic after an earlier lesson or study attempt. Choose examples appropriate to your background and allow time to work through the method instead of judging understanding only by how familiar the terminology sounds.

Before you start

Basic arithmetic and comfort interpreting a graph are useful. Follow the assumptions of each model rather than treating every simplified example as a real-world prediction.

Put the lessons into practice

Build a fictional two-good economy for two periods. Calculate nominal output, compare real output using a stated base period and explain the implied price change. Add a small labor-force table and compute an unemployment rate with the correct denominator. Write a short commentary separating what the indicators show from welfare or causal claims they cannot establish alone.

This optional study activity is provided by WikiFree for independent practice. Keep your working notes and use the relevant classroom recording to check a step, definition or interpretation. It is not an instructor-marked assignment.

Certificate / Assessment

Watching the public videos and using WikiFree completion tracking does not award a certificate, academic credit, an examination voucher or instructor assessment. Use your practice output to review what you can explain and repeat independently. The recorded lessons provide study material; completion tracking records your progress through that material.
