According to the keynesian model, what are the two components of consumption spending? what factors determine how consumption changes when real disposable income changes? explain.

A simple Keynesian model follows four principles:

1. Accumulated expenditures, income, and output are the same.
2. All input of spending into the economy must equal all withdrawals
3. Investment is an input.
4. Saving is a withdrawal

According to Keynesian analysis, of households intend to save more, they will become poorer. The theory about Keynesian analysis applies to economic where an increase in savings decreases the circular flow of income. S when the households save more, they are reducing the stream of income for other households and therefor diminishes the overall economic activity.

What is the question?

The business cycle is the periodic but irregular up-and-down movement in economic activity, measured by fluctuations in real gross domestic product (gdp) and other macroeconomic variables. a business cycle is typically characterized by four phases—recession, recovery, growth, and decline—that repeat themselves over time. economists note, however, that complete business cycles vary in length. the duration of business cycles can be anywhere from about two to twelve years, with most cycles averaging six years in length. some business analysts use the business cycle model and terminology to study and explain fluctuations in business inventory and other individual elements of corporate operations. but the term "business cycle" is still primarily associated with larger (industry-wide, regional, national, or even international) business trends.
