(10) ILO measure of unemployment: Defines unemployment as people who are jobless, have been looking for job since the past four weeks and able to take up the job two weeks from the date of interview
(11) Demand management policies: Policies to influence the movement of AD such as fiscal and monetary policy
(12) Economic growth: Rise in real GDP/ rise in potential GDP
(13) GDP: The value of all goods and services produced within an economy
(14) Real GDP: Value of all goods and services produced within an economy adjusted for inflation
(15) Real GDP growth: An increase in the value of all goods and services produced within an economy adjusted for inflation
(16) Hot money: Defined as short term, speculative flows of money between countries
(17) HDI (Human Development Index): A measurement of economic development comprised of three components which are health, education and GDP per capita
(18) Inflation: Sustained increase in price level
(19) Injection: An inflow of money into the circular flow of income. Components of injections are investment, government spending and exports
(20) Withdrawal/ leakages: An outflow of money from the circular flow of income. Components of leakages are savings, tax and imports
(21) Investment: Change in capital stock such as the purchase of plants and machineries
(22) Monetary policy: Is the manipulation of interest rates to influence the movement of AD and overall level of economic activity
(23) Multiplier: An initial increase in injection which will lead to a larger secondary increase in AD
(24) Productivity: Output per worker/ unit of input
(25) Supply side policies: Policies to influence the movement of AS by increasing the productive capacity of an economy
(26) Employment rate: Percentage of people who are willing and able to work who are in employment
(27) Unemployment rate: Percentage of people who are willing and able to work but not in employment

Handy Definitions For Unit 1: Markets: How They Work and Why They Fail?
(1) Production possibility frontier (PPF). A curve that shows the combination of two goods that can be produced in an economy shall all resources are fully & efficiently used
(2) Opportunity cost. The next best alternative forgone
(3) Specialisation. Process of breaking up a task into a number of repetitive operations each done by different workers
(4) Free market economy. An economy where resources are all privately owned & price mechanism will act to allocate resources
(5) Command economy. An economy where all resources are publicly owned & state government will intervene to allocate resources
(6) Mixed economy. An economy where resources are owned & allocated by both private sector & government
(7) Positive statement. Statement that can be proven true or false by referring to facts
(8) Normative statement. Value judgement & cannot be proven true or false
(9) Substitutes. Goods that can be used in place of another

(14) Cross elasticity of demand (XED). Measures the responsiveness of demand for a good (say Good X) to a change in the price of another good (say Good Y)
(15) Income elasticity of demand (YED). Measures the responsiveness of demand for a good to a change in income
(16) Price elasticity of supply (PES). Measures the responsiveness of supply for a good to a change in its own price
