Q

Circular Flow of income

A

The flow of income between households (consumers) and firms. Expenditures on goods and services flow from households to firms, and income flows from firms to households. Leakages may flow out of the economy, but flow back in by injections.

Q

Methods of Calculating Gross Domestic Product (2): National Output Approach

A

the sum total of all final goods and services added together over a time period of usually one year, calculated by summing up the value-added at each stage of production
• This avoids “double-counting intermediate goods”.
- It is important not to count intermediate goods and services, example steel that produces cars

Q

Natural rate of employment

A

Unemployment resulting from a situation where there is no cyclical unemployment, only structural, frictional and seasonal. It is seen as the rate of full employment where demand for labor equals the supply of labor.
• Full employment and the natural rate of unemployment are really the same thing.
• Increase in demand at this level will cause inflation.

Q

Full Employment (Level of National Income)

A

This is the level at National Income at which everyone who wants to work is able to. It is the level of employment rates where there is no cyclical or deficient-demand unemployment.
• This is NOT 0% unemployment as there will exist frictional and some structural unemployment.

Q

Keynesian Model (John Maynard Keynes)

A

Economic viewpoint: Economy is INHERENTLY UNSTABLE and can remain in a recessionary or inflationary period INDEFINITELY. The government NEEDS TO INTERVENE to correct this imbalance. How:
• During a recession/deflationary period the government needs to induce spending or “prime the pump” (aggregate demand). During an inflationary period the government needs to use measures to decrease spending (aggregate demand).
• Note: The aggregate supply curve goes from horizontal to vertical!!!!

Q

Neo-Classical Model (New Classical Model)

A

Economic Viewpoint: The economy is inherently stable, and although there may be periods where the economy slows down, it will self-correct. The government should intervene as little as possible.
• Markets operate more efficiently when the government stays out of the economy.
• Note: According to this model the SRAS curve is upsloping!!
• Flexible prices, wages, and interest rates

Q

Recessionary Gap (or Deflationary Gap)

A

Where an economy is operating below its full employment equilibrium. There are unemployed resources!

• Under this condition, the level of real GDP is currently lower than its full employment, which puts downward pressure on prices in the long-run.

Q

Inflationary Gap

A

A macroeconomic condition that describes the distance between the current level of real GDP and the full employment (long run equilibrium) real GDP. Real GDP is higher than full-employment GDP and there is upward pressure on prices.

37
Q

Spare capacity

A

a situation when some factors of production are unemployed

38
Q

Labor Force

A

people who are 16 years or older (may be different in some countries), and are working or who are actively seeking work

39
Q

Unemployment

A

occurs when there are people actively looking for work at the equilibrium wage rate but are not able to find work

40
Q

Unemployment benefits

A

regular payment made by the government to those who are unemployed. (most developed countries automatically give benefits to those that are laid-off, but NOT to those who are fired)

41
Q

Unemployment Rate

A

The number of unemployed expressed as a percentage of the labor force

42
Q

Demand deficient or cyclical unemployment

A

Unemployment caused by the business cycle where the slowdown in economic activity with falling aggregate demand is the cause of unemployment.

43
Q

Frictional unemployment

A

unemployment as a result of people who are between jobs, or are entering, or reentering the job market ( labor force).
• It often takes time for workers to find jobs, even though there are jobs. It is often seen as a healthy for an economy to have workers move into areas of need.

44
Q

Structural unemployment

A

unemployment caused by a change in the demand for skills as the nature or structure of the economy changes (dynamic economy).
• So there is a mismatch between qualifications, skill-sets and characteristics of the unemployed and available jobs. Example: Car workers, steel workers in the US.

45
Q

Seasonal unemployment

A

unemployment associated with industries or regions where the demand for labor is lower at certain times of the year.

46
Q

Real-wage unemployment

A

disequilibrium unemployment being driven up above the market clearing rate. It is caused my non-market forces entering the labor market such, as Government imposed minimum wage, or labor unions pushing up wages.

47
Q

Discouraged worker

A

is someone who has left the labor force because they cannot find work. In other words, discouraged workers are unemployed people that were looking for work but have given up and therefore are NOT in the labor force.
• Discouraged worker may distort unemployment statistics

48
Q

Underemployment

A

A situation where a country there are highly skilled workers but working in low-paying jobs, and/or workers who are working part time but would prefer full-time work.
• example: people in part-time work who would like to work more. This is seen as a problem in China, the Philippines, Mexico, etc. Someone working under their education level, or selling fruit on the streets would be considered underemployed

49
Q

Hidden unemployment

A

the number of people who do not have work but who are not counted in government reports, for example, people who have stopped looking for a job (discouraged workers) and people who work less than they want to (part time)
• Usually mean “real unemployment rates” may be much higher than government claims.

50
Q

Inflation

A

Inflation is the sustained (persistent) upward movement in the average level of prices.

51
Q

Rate of Inflation

A

The percentage increase in the price of goods and services, usually annually. Most commonly associated with the Consumer Price Index

52
Q

Consumer Price Index

A

Measures the change in purchasing a fixed basket of goods and services from one time period to another. A price index measuring average prices over time!

53
Q

Price Stability

A

When the average level of prices is moving neither up or down.

54
Q

Money illusion

A

the idea that people consider the nominal value of money rather than its real value thus ignoring the purchasing power of their income. People therefore have an unrealistic picture of their income and wealth.

55
Q

Demand Pull Inflation

A

Inflation induced by a persistence of an excess of aggregate demand in the economy over aggregate supply. Can be looked at as too much money chasing too few goods and services.

56
Q

The Quantity of Money Theory (excess monetary growth)

A

claims that in the long-run an increase in the quantity of money causes an equal increase in the price level

57
Q

Cost Push Inflation

A

the situation in an economy where there is sustained prices rises because of production costs increasing, example wages, imported materials, interest rates and rents.

58
Q

Supply-side shocks

A

occurs when there is an unexpected change in the supply of a f actor of production resulting in a sudden change in its price

59
Q

Deflation

A

A sustained (or persistent) decrease in the general price level (Japan, Hong Kong) where the rate falls below zero.

60
Q

The Phillips Curve

A

strong inverse relationship between inflation and unemployment.

61
Q

Long-Run Phillips Curve

A

In the long run this trade-off between inflation and unemployment does not tend to occur. Unemployment will gravitate toward the natural rate of unemployment.

62
Q

Stagflation

A

occurs when an economy experiences a period of increasing inflation, negative or zero economic growth and rising unemployment.

63
Q

Progressive Tax

A

system of tax where the percentage paid in tax increases as income increases.
-Used by most MDC’s as a form of income tax (direct) collection. (also an automatic fiscal stabilizer)

64
Q

Regressive Tax

A

tax regime where the percentage of tax paid is lower the higher the income, so proportionally less tax is being taken from higher income earners. Sales tax is an example of a regressive tax

65
Q

Proportional Tax

A

A tax which is levied at the same rate for all, regardless of income. Often called a flat tax.
-For example everyone might pay 15% of their income in tax.

66
Q

Direct Tax

A

a tax leveled on factor incomes.

-Examples: tax paid by individuals on income, tax paid by companies on profit.

67
Q

Indirect tax

A

taxes on the production, sale purchase or use of a good

– usually producer taxed so it passes (indirectly) onto the consumer -example sales tax on new cars.

68
Q

Disposable Income

A

total income households receive from wages, salaries and transfers from governments less taxation

69
Q

Discretionary Income

A

part of disposable income that is used to undertake new consumption expenditure

70
Q

Transfer Payments

A

payments received by persons from the government in the form of social payments
i.e. social security payments, income support, subsidies) payments are being transferred from financial resources collected by one group in society and given to another group

71
Q

Gini coefficient

A

a statistic used to measure the extent of equality in distribution, usually income and wealth. It is measured between 0 and 1 with 0 being perfect equality and 1 being perfect inequality

72
Q

Demand-side policies

A

Government policy that attempts to alter the level of AD to complement government policy and stabilize the economy. Consist of Fiscal and Monetary policies.

73
Q

Fiscal Policy (Budgetary policy)

A

Policy regarding the size and composition of government spending and revenue used to influence both the level and pattern of economic activity in a country. It can be either expansionary or contractionary to either increase or decrease economic activity and influence aggregate demand.

74
Q

Expansionary Fiscal Policy

A

will involve increasing government expenditure or decreasing taxes (an injection in the circular flow) –will lead to increased AD and multiplied rise in AD.

75
Q

Contractionary Fiscal Policy

A

cutting government spending and/or raising taxes (a leakage from the circular flow) –will lead to decreased AD and multiplied decrease in AD

76
Q

Business confidence

A

is related to the expectations of businesses about the future of economic conditions, (which may be optimistic or pessimistic) and affects the level of investment.

77
Q

Austerity Measures

A

Increasing taxes and cutting government spending in order to reduce a budget deficit. Has the effect of contracting the economy (even though tis may lead to an even worse economic situation).
i.e. Greece, Spain, Portugal, Italy 2012-2014.

78
Q

Budget Surplus

A

The excess of central government tax receipts (revenue) over its spending for one year.

79
Q

Budget Deficit

A

The excess of central government spending over its receipts (revenue) for one year.

80
Q

Automatic fiscal stabilizers

A

Fiscal policy that works without using a discretionary government policy. The economy automatically contracts (slows down) during an inflationary period, and expands during a recessionary period.

  • Progressive tax system will automatically increase the rate of taxation as income rises and thus slow down the potential rise in AD and decrease the rate of taxation as income rises increasing AD.
  • Unemployment benefits, and other recessionary spending also act as automatic stabilizers.
81
Q

Discretionary Fiscal Policy

A

deliberate changes in tax rates and government spending to influence level of AD

82
Q

Crowding Out

A

A situation where government spending displaces (or crowds out) Private Investment. (The government is competing for the same money businesses and consumers want…it drives up the interest rate)
Note: Be able to show this graphically using a Loanable Funds Market Supply and Demand diagram!!!!

83
Q

Monetary Policy

A

The central bank policy with respect to the quantity of money in the economy to affect the rate of interest and aggregate demand. Now broadly accepted as the primary determinant/weapon to influence of AD

84
Q

Expansionary Monetary Policy (Easy Money)

A

An increase in the money supply in order to lower interest rates and increase Consumption and Investment. Used to counter or correct a recession. More recently known as QUANTITATIVE EASING (QE).
i.e. QE1 and QE2 were recently used in 2009 & 2011& 2013 in the United States by the Federal Reserve bank (the FED) in order to stimulate growth in the sluggish economy.

85
Q

Contractionary Monetary Policy (Tight Money)

A

A decrease in the money supply in order to increase interest rates and decrease Consumption and Investment. Used to counter or correct inflation or inflationary pressure.
i.e. Used in China in 2010-2011 to try and contain inflationary pressure in the
economy

86
Q

Supply Side Policies

A

Are mainly microeconomic policies designed to improve (incease) the supply-side potential of an economy, make markets and industry operate more efficiently, and therefore contribute to a faster rate of growth of real national output.
Note: May be Market-based supply side policies (no government intervention) or Interventionist supply side policies.

87
Q

Capital Gains

A

income earned though the selling of an asset.

i.e. Selling stocks at a higher price than bought, or selling a house at a higher price.

88
Q

Laffer Curve

A

A diagram the shows the relationship between government revenue and the % tax rate. At 0% tax rate and a 100% tax rate the government would be zero. At some percentage rate government revenue would be maximized. It is used to show that increasing marginal tax rates too much may discourage investment and work and will cause a decrease in government revenue.
