Macroeconomics 1 Flashcards
What is the circular flow of income
A model of the economy showing money flows between households and firms. Consumption and income flows as financial flows for factors of productions and goods and services
How do households gain factor incomes
Households gain factor incomes for providing their factors of production to produce goods and services
Where do households spend their income
Households will spend their income on firms’ goods and services
What is GDP
The key measure of national income - Gross Domestic Product
What are the injections into the circular flow
Money can be injected into the circular flow via business investment (I), Government spending (G) and exports (X)
What are the withdrawals from the circular flow
Savings (S), taxation (T) and imports (M)
What represents economic growth in the circular flow
When injections are greater than withdrawals as the amount of money in the circular flow increases
What represents a fall in GDP in the circular flow
When injections are less than withdrawals so the amount of money in the circular flow decreases
What is the multiplier effect
The number of times a rise in income exceeds the rise in injections that caused it
What is the multiplier ratio
The ratio of a change in equilibrium real income to the autonomous change that brought it about
How can investment increases cause the multiplier effect
If a firm is successfully expanding then there should be more profit to distribute to shareholders. Increase income for shareholders means increase spending which will generate more profit for firms to invest and expand further
How can government spending cause the multiplier effect
More government spending means more jobs in the public sector which means increased spending of workers which would generate more profits for firms to invest and expand
How can export increases cause the multiplier effect
More exports and therefore more profits and earnings. Increase shareholder dividends and the possibility of new jobs increases leading to higher income for households therefore more spendings which would generate more profits for firms to invest and expand
Relationship between withdrawals and the multiplier affect
The higher these withdrawals the smaller the size of the multiplier overall
Definition of MPC and how to calculate it
Marginal propensity to consume is the proportion of additional income that is spent. MPC = Change in consumption divided by change in income
Definition and how to calculate MPS
Marginal propensity to save is the proportion of additional income that is saved. MPS = Change in saving divided by change in income
Definition and how to calculate MPT
Marginal propensity to tax is the proportion of additional income that is taxed. MPT = Change in tax payed divided by change in income
Definition and how to calculate MPW
Marginal propensity to withdraw is the proportion of additional income that is withdrawn from the circular flow in tax, saving or imports. MPW = Change in withdrawals (MPS+MPT+MPS) divided by change in income
Definition and how to calculate MPM
Marginal propensity to import is the proportion of additional income that is spent on imports. MPM = Change in imports purchased divided by change in income
How to calculate the size of the multiplier
1 divided by (1-MPC) = 1 divided by (MPW)
Definition of income
A flow of money which acts as a reward for the services of factors of production
Definition of wealth
The stock of assets held by an individual or organisation
Difference between real and nominal income
Real income adjusts income for the effects of inflation whereas nominal income does not
Examples of income
Wages, salaries, interest on savings, profits/ dividends
