Course Overview

The source curriculum is presented as a complete recorded video edition of Income and Wealth: Economic Data Analysis. Representative lessons include “Introduction to series analyzing income and wealth trends in the US”, “Comparing income trends across countries” and “US taxation trends in post war era”. These recordings give concrete examples to revisit while building economic models, incentives and cause-and-effect explanations. Their place in the lesson list is preserved, so you can return to a particular explanation without losing its source position. Introductions, demonstrations, examples, reviews and compilations remain included whenever they appear in the original playlist. Reading a lesson title is useful for locating a topic; working through its reasoning and checking a practice attempt is what makes the recording valuable for learning.

How to study the course

• Videos 1–1: this part of the source list includes “Introduction to series analyzing income and wealth trends in the US” through “Introduction to series analyzing income and wealth trends in the US”. 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 2–2: this part of the source list includes “Looking at trends in inflation adjusted income since 1980” through “Looking at trends in inflation adjusted income since 1980”. 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 3–3: this part of the source list includes “Comparing income trends across countries” through “Comparing income trends across countries”. 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 4–5: this part of the source list includes “Per capita GDP trends over past 70 years” through “US taxation trends in post war era”. 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

Develop a fictional example using a model from the recordings. Name the participants, quantities and assumptions, then explain how a change affects the situation. Use the graph, table or calculation demonstrated in the course when appropriate. Compare the original and changed cases and separate a movement within the model from a change in its assumptions. Write a short explanation of the mechanism involved. Identify one additional fact you would need before applying the same reasoning to an actual situation.

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.
