• 😀 Household savings that are not spent on consumption are deposited in financial institutions, which companies can use for investments.
• 😀 A consumption schedule shows the relationship between household income and consumption, with some income being used for savings if it exceeds consumption needs.
• 😀 The relationship between income and consumption suggests that households save more when their income exceeds consumption, especially at higher income levels.
• 😀 Marginal Propensity to Consume (MPC) is the ratio of the change in consumption to the change in disposable income, showing how consumption increases with income.
• 😀 Average Propensity to Consume (APC) is the ratio of total consumption to total disposable income, providing insight into general consumption habits.
• 😀 The Marginal Propensity to Save (MPS) is the ratio of the change in savings to the change in disposable income, reflecting how savings increase with income.
• 😀 The function of consumption and saving in macroeconomics examines the behavior of all households in an economy, not just individual households.
• 😀 Aggregate consumption and savings refer to the total consumption and savings of all households in an economy, influencing national income and economic equilibrium.

Q & A

What is the two-sector economy mentioned in the script?

The two-sector economy refers to an economic system consisting of two primary sectors: households and firms. This system does not include government activities or foreign trade.

How is income circulated in a two-sector economy?

In a two-sector economy, income circulates through the interaction between households and firms. Households provide factors of production to firms, and in return, they receive income in the form of wages, rents, interest, and profits. This income is then used for consumption or savings.

What happens to the income not spent on consumption in a two-sector economy?

The income not spent on consumption is saved and deposited in financial institutions. These savings are then used by firms for investment purposes.

What does the consumption schedule in the script illustrate?

The consumption schedule illustrates the relationship between the income of households and their consumption levels. It shows how household consumption changes as income levels fluctuate.

What happens when a household's income is lower than its consumption?

When a household's income is lower than its consumption, it will use its savings or even borrow money to cover the gap. This can lead to negative savings or debt accumulation.

How is the relationship between consumption and income characterized in the script?

The relationship between consumption and income is such that as income increases, consumption typically increases, but at a slower rate. This means that a portion of increased income is saved rather than spent.

What is Marginal Propensity to Consume (MPC)?

Marginal Propensity to Consume (MPC) is the ratio of the change in consumption to the change in disposable income. It measures how much more households will consume as their income increases.

What does the Average Propensity to Consume (APC) refer to?

Average Propensity to Consume (APC) refers to the ratio of total consumption to total disposable income, showing the overall consumption behavior of households in relation to their income.

What are the key factors that determine investment levels in an economy?

Key factors that determine investment levels include expected profits, interest rates, economic forecasts, technological advancements, and the level of national income.

What is the difference between gross investment and net investment?

Gross investment includes all investments made to increase production capacity, such as purchasing machinery and constructing buildings. Net investment is the total gross investment minus depreciation, representing the actual increase in capital stock.
