The Concept of Economics.

One person says economics is about wealth. Another says it is about human welfare. A third says it is the tug of war between endless wants and scarce resources. All three are famous economists, and the exam will ask who said what, and where each of them left a gap.

1. The classical view: Adam Smith

Adam Smith, David Ricardo and John Stuart Mill considered economics to be the science of the production and distribution of wealth. With the progress of knowledge and science the scope of economics has grown a great deal, and this section follows that growth.

Adam Smith is called the Father of Economics, and this school is known as classical economics. Classical economists believed in laissez faire, which means the government interferes as little as possible in economic activity.

Smith's definition: “Economics is a science that examines the nature and causes of the wealth of nations.” For him the economy is built around wealth, so gathering and producing wealth is the main aim of economic activity.

2. Four weaknesses in Smith's definition

The book points to four gaps in Smith's definition. Keep them one by one.

3. The neoclassical view: Marshall

Professor Alfred Marshall's definition: “Economics studies the general activities of human life.”

Marshall stressed human welfare more than wealth. The main subject, in his view, is how people earn money and spend it to remove their wants. The main aim is the welfare of people.

Where is the gap? Scarcity of resources, the core problem of economics today, is not considered in his definition. He discussed only the actual welfare of people.

Marshall and his followers Robbins, Jevons, Walras, Edgeworth and Pareto are known as neoclassical economists.

4. Robbins' definition and its criticism

Professor L. Robbins' definition: “Economics is a science that studies human behaviour as a relationship between unlimited wants and scarce resources which have alternative uses.”

This one is more precise and more acceptable, for four reasons. Wants are unlimited and varied. Resources and time are limited. The same resources have to serve different wants. And wants are met by priority.

Even so, it is criticised on three counts:

Each definition is like a lamp: some things fall in its light, some stay in the dark. What stays in the dark is the criticism. Shine them one at a time.

What each definition leaves out

Now say whose each of seven criticisms is. Pick up a chip, then drop it in the Smith, Marshall or Robbins box.

Whose criticism?

Pick up a chip, then drop it in a box. Ask: is it about wealth, about welfare, or about wants and scarcity?

5. The Great Depression and Keynes

In the Great Depression of the 1930s the laissez faire policy of the classical and neoclassical economists failed. The British economist John Maynard Keynes then argued strongly for government intervention. Tap the schools in the order they came.

which first which came after which?

Order of the schools

Start with the school of the Father of Economics.

Keynes's remedy is simple: raise government spending and cut the tax rate. That increases aggregate demand and helps the economy climb out of recession.

Try Keynes's remedy yourself. At first the government keeps its hands off; then raise spending and cut taxes.

out of the slump drag spending and tax

Government spending, tax and aggregate demand

The scales are made up and only show the direction: what raises demand.

6. Put the four side by side

The exam often asks whose words these are. Tap a cell in the grid and the whole view of that economist appears below.
