What traumatic event does Zitkala-Sa describe at the school?

What is the difference between microeconomics and macroeconomics?

Microeconomics studies individual agents and single markets, while macroeconomics studies the economy as a whole using aggregate measures like total output and employment.

How did macroeconomics emerge as a separate branch?

It emerged after Keynes published The General Theory in 1936, as the classical view could not explain the mass unemployment of the Great Depression.

What were the effects of the Great Depression of 1929?

Output and employment fell sharply; in the USA unemployment rose from about 3% to 25% and aggregate output fell by roughly one-third.

What are the main features of a capitalist economy?

Private ownership of the means of production, production for sale in the market, and the sale and purchase of labour services at a wage rate.

Name the four major sectors of an economy in macroeconomics.

Households, firms, the government, and the external sector.

What roles do households play in the economy?

They consume goods and services, save, pay taxes, and supply factor services such as labour, earning wages, rent, interest and profit.

How does the external sector link the domestic economy to the world?

Through exports and imports of goods and services and inflows or outflows of capital.

Why are macroeconomic decision-makers different from individual agents?

Because bodies like the government and the RBI pursue public goals such as employment and price stability rather than maximising private profit.

What four factors of production exist in a capitalist economy and what do they earn?

Land earns rent, labour earns wages, capital earns interest, and entrepreneurship earns profit.

Why can a single representative good be used in macroeconomic analysis?

Because the outputs, prices and employment levels of different goods tend to move together, so one imaginary good can represent the averages of the economy.

Summary

Macroeconomics studies the economy as a whole, focusing on aggregates such as total output, the general price level, employment and growth rather than individual markets. It treats the many goods of an economy as a single representative good whose price and output reflect the economy’s averages, because aggregate variables tend to move together. The subject emerged as a separate branch after John Maynard Keynes published The General Theory of Employment, Interest and Money in 1936, prompted by the Great Depression of 1929 when output and employment in Europe and North America collapsed and classical economists could not explain prolonged unemployment. The book studies the working of a capitalist economy, where production is carried out by private firms using factors of production — land, labour, capital and entrepreneurship — which earn rent, wages, interest and profit, and where output is produced for sale in the market using wage labour. Macroeconomics views the economy as four interacting sectors: households (who consume, save and supply labour), firms (who produce), the government (the State, which taxes, spends and frames laws), and the external sector (which trades through exports and imports and capital flows). Macroeconomic decision-makers such as the government and the Reserve Bank of India pursue public goals like full employment and price stability rather than private profit.
