different possible price levels, in a year, ceteris paribus.
the total amount of real output (goods and services) produced in an economy in a year at different price levels; there are three kinds of AS curves: short-run aggregate supply (SRAS), long-run aggregate supply (LRAS) and Keynesian AS.

future of the economy
spending by consumers to buy goods and services
policy carried out by the government (fiscal policy) or the central bank (monetary policy) intended to lower AD and close an inflationary gap.
inflation caused by a decrease in SRAS, hence a leftward shift in the SRAS curve, resulting mainly from increases in costs of production or supply shocks.
a possible weakness of expansionary fiscal policy involving increases in
government spending financed by borrowing, causing an increase in interest rates that reduces
consumption and investment spending, thus counteracting the increase in AD.
spending by the government for its day-to-day operations (wages of government workers, supplies, subsidies)
(demand-deficient unemployment) = unemployment caused by decreases in AD, leading to the downward phase of the business cycle.
a sustained decrease in the general price level
occurs when short-run equilibrium GDP is less than potential GDP due to insufficient aggregate demand.

the total income received by the residents of a country
in a year, regardless of where the factors of production owned by the residents are located.
people without a job not included in official unemployment figures because they are not actively seeking a job (ex "discouraged workers") as well as
underemployed people counted as fully employed in official unemployment figures.
an approach to measuring GDP that adds up all income earned by the factors of production in the course of producing total output within a year; includes wages, rent, interest and profits.
taxes on spending to buy goods and services, paid indirectly to the government through the sellers (ex sales taxes, VAT)
a type of interventionist supply-side policy intended to promote specific
industries; include tax reductions, tax exemptions, low-interest loans, subsidies and grants for
industries that are held to be important to support growth.
a sustained increase in the general price level
a policy pursued by some central banks focusing on targeting a particular
rate of inflation and carrying out monetary policy (manipulation of interest rates) to achieve the
targeted rate.
occurs when short-run equilibrium GDP is greater than potential GDP due to excess aggregate demand.
money that enters the circular flow of income in the form of investment spending, government spending or export revenues (spending by foreigners)
payment for borrowed money over a certain time period, expressed as a percentage of the borrowed amount; the "price" of money services.
spending by firms or the government to buy capital
goods (machines, equipment, as well as infrastructure)
an AS curve with a horizontal section (when the economy is in recession), an upward-sloping section (when the economy approaches full employment output) and a vertical section (when the economy has reached maximum capacity output).
money that leaves the circular flow of income in the form of saving, taxes, and spending on imports
an AS curve showing real output produced as being
independent of the price level; the LRAS is vertical at real GDP where unemployment= natural unemployment.
visual representation of income shares received by percentages of the population; the further away a Lorenz curve is from the line of perfect equality, the more unequal the distribution of income; forms the basis of computing the gini coefficient.
a type of demand-side policy undertaken by the central bank in order to manipulate AD (by changing interest rates) to achieve price stability and low unemployment.
the sum of frictional, seasonal and structural unemployment; is the unemployment level of the economy when it is producing potential output (= full employment output).
the value of exports minus the value of imports
a measure of output and income in terms of current prices (prices at any given moment in time).
an approach to measuring GDP that adds up the value of each good and
service (PxQ) produced in the economy within a year, thus obtaining the value of all final goods
and services
the level of real GDP produced when the
economy is on its long-term growth trend, where cyclical unemployment= 0 and unemployment = natural unemployment.
the inability to satisfy basic physical needs (ex, food, clothing, shelter, etc) due to low income.
output per worker; it increases as a result of investments in physical, human and natural capital; a major cause of economic growth
the percentage of income paid as tax (average tax rate) increases as income increases.
the percentage of income paid as tax (average tax rate) remains constant as income increases
a measure of output and income in terms of constant prices that prevail in one particular year; therefore, real values eliminate the influence of price level changes
over time.
falling real GDP over a period of at least two consecutive quarters (six consecutive months).
the percentage of income paid as tax (average tax rate) decreases as income increases.
the number of people with an income level below a predefined level that changes over time, defined as a percentage of society's median income; poverty is "relative" to other people's income; reflects the idea that people should be able to afford a lifestyle typical of
their society.
unemployment including workers who are unemployed on a seasonal basis, ex ski instructors in the summer.
an AS curve showing the total amount of real output
produced in a year to be directly related to the price level.
unemployment that is usually long-term, arising from changing demand for different labor skills (due to technological change or structural changes in the
economy), changes in the geographical location of industries, and labor market rigidities.
transfers of income from taxpayers to vulnerable groups who are people in need, including unemployment benefits, child allowances, pensions, housing benefits and others.
policies that focus on the supply side of the economy, aiming to promote long-term economic growth and hence increase potential output (increase LRAS or Keynesian AS); may be interventionist (involving government intervention in the economy) or market-based (based on development of free competitive markets).
people who are employed, but who (i) work part-time when they would rather work full-time, and (ii) work at a different skill or lower skill level than what they were
trained for (ex an engineer working as a waiter).
the number of people in the labor force actively looking for work but without a job, expressed as a percentage of the labor force (= number of unemployed / labor
force x 100).
curve showing relationship between rate of inflation and rate of unemployment. Short run Phillips curve shows an inverse relationship, but long run Phillips curve is vertical at the natural rate of unemployment indicating that unemployment is independent of the price level.
arises from a decrease in SRAS which causes a rising price level (cost push inflation) and a fall in output.
