macroeconomics, such as short-run fluctuations in
employment and savings rates, in order to develop
a model that attempted to describe the long-run
evolution of the economy

3. G r o s s D o m e s t i c P r o d u c t
The monetary value of all the finished goods and services produced within a country's borders in a
specific time period, though GDP is usually calculated on an annual basis. It includes all of private and
public consumption, government outlays, investments and exports less imports that occur within a defined
territory.
GDP = C + G + I + NX
where:
"C" is equal to all private consumption, or consumer spending, in a nation's economy
"G" is the sum of government spending
"I" is the sum of all the country's businesses spending on capital
"NX" is the nation's total net exports, calculated as total exports minus total imports. (NX = Exports -
Imports)

4. The recurring and fluctuating levels of economic activity that an economy experiences over a long period
of time. The five stages of the business cycle are growth (expansion), peak, recession (contraction),
trough and recovery. At one time, business cycles were thought to be extremely regular, with predictable
durations, but today they are widely believed to be irregular, varying in frequency, magnitude and duration.

5. The risk of business cycles or other economic cycles adversely affecting the returns of an investment, an
asset class or an individual company's profits. Cyclical risks exist because the broad economy has been
shown to move in cycles – periods of peak performance followed by a downturn, then a trough of low
activity. Between the peak and trough of a business or other economic cycle, investments may fall in
value to reflect the uncertainty surrounding future returns as compared with the recent past.
Cyclical risk can also be tied to inflationary risks, as some investors consider inflation to be cyclical in
nature.
C Y C L I C A L R I S K

6. A significant decline in activity across the economy, lasting longer than a few months. It is visible in
industrial production, employment, real income and wholesale-retail trade. The technical indicator of a
recession is two consecutive quarters of negative economic growth as measured by a country's gross
domestic product (GDP); although the National Bureau of Economic Research (NBER) and other
institutions do not necessarily need to see this occur to call a recession.
R E C E S S I O N

7. According to Keynesian economics, the amount left over when the cost of a
person's consumer expenditure is subtracted from the amount of disposable
income that he or she earns in a given period of time.
S AV I N G S
A tri-lateral relationship among savings, consumption, and income is the key determinant of the amount
of personal savings. On the first side, given a certain income, the decision to buy goods and services
(=consumption) negatively affects savings. Savings passively adjust to consumption and income. They
represent a resource slack, buffering shocks in income and consumption desires.
On a second side, savings can be actively planned in binding agreements, like many pension schemes,
with consumption passively adjusting to changes in income.
In other terms, savings can arise from a compulsory tendency of renouncing and postponing even banal
consumption (greediness) or, instead, they can be the result of sharply rising income, with higher
consumption taking place meanwhile.
By contrast, savings can be also the outcome of negative expectations about future income (as when one
is afraid of being dismissed)

8. The percentage of the total labor force that is unemployed but actively seeking employment and willing to
work.
U N E M P L O Y M E N T R AT E
Structural unemployment
Unemployment that comes from there
being an absence of demand for the
workers that are available
Changes in Technology
Changes in Tastes
Frictional Unemployment
Unemployment that comes from people moving
between jobs, careers, and locations
People entering the workforce from school.
People re-entering the workforce after raising
children.
People changing employers due to quitting or being
fired (for reasons beyond structural ones).
People changing careers due to changing interests.
People moving to a new city (for non-structural
reasons) and being unemployed when they arrive.
Cyclical Unemployment
Occurs when the unemployment rate moves in the
opposite direction as the GDP growth rate. So when
GDP growth is small (or negative) unemployment is
high.
Getting laid off due to a recession is the classic
case of cyclical unemployment
Seasonal Unemployment
Unemployment due to changes in the
season - such as a lack of demand
for department store Santa Clauses
in January. Seasonal unemployment
is a form of structural unemployment,
as the structure of the economy
changes from month to month.

Labor Productivity
Output divided by the
number of workers or,
more often, by the
number of hours
worked.

10. A competitive advantage is one that an organization has over its competitors,
allowing it to generate greater sales or margins and/or retain more customers
than its competition. There can be many types of competitive advantages
including the firm's cost structure, product offerings, distribution network and
customer support.
C O M PA R AT I V E A D VA N TA G E
According to the classical theory of international trade, every country will produce their commodities for
the production of which it is most suited in terms of its natural endowments climate quality of soil, means
of transport, capital, etc. It will produce these commodities in excess of its own requirement and will
exchange the surplus with the imports of goods from other countries for the production of which it is not
well suited or which it cannot produce at all. Thus all countries produce and export these commodities in
which they have cost advantages and import those commodities in which they have cost disadvantages.

11. O P P O R T U N I T Y C O S T
The cost of an alternative that must be forgone in order to
pursue a certain action. The benefits you could have
received by taking an alternative action. The difference in
return between a chosen investment and one that is
necessarily passed up. Say you invest in a stock and it
returns a paltry 2% over the year. In placing your money in
the stock, you gave up the opportunity of another
investment - say, a risk-free government bond yielding
6%. In this situation, your opportunity costs are 4% (6% -
2%).

12. Even though the concepts of supply and demand are introduced separately, it's the combination of these
forces that determine how much of a good or service is produced and consumed in an economy and at
what price. These steady-state levels are referred to as the equilibrium price and quantity in a market. In
the supply and demand model, the equilibrium price and quantity in a market is located at the intersection
of the market supply and market demand curves. Note that the equilibrium price is generally referred to as
P* and the market quantity is generally referred to as Q*.

14. A measure of a variable's sensitivity to a change in another variable. In economics, elasticity refers the
degree to which individuals (consumers/producers) change their demand/amount supplied in response to
price or income changes.

15. A financial benefit that is realized when the amount of revenue gained from a business activity exceeds
the expenses, costs and taxes needed to sustain the activity. Any profit that is gained goes to the
business's owners, who may or may not decide to spend it on the business.
Calculated as:
P R O F I T

16. I N F L AT I O N
The overall general upward price movement of goods and services in an economy (often caused by
a increase in the supply of money), usually as measured by the Consumer Price Index and the Producer
Price Index.
Demand-Pull Inflation
When spending on goods and services drives up prices.
Demand-pull inflation is fueled by income, so efforts to stop it
involve reducing consumer's income or giving consumers more
incentive to save than to spend.
Cost-Push Inflation
When the price of inputs increases. Businesses must acquire raw
materials, labor, energy, and capital to operate. If the price of these
were to rise, it would reduce the ability of producers to generate
output because their unit cost of production had increased. If these
increases in production cost are relatively large and pervasive, the
effect is to simultaneously create higher inflation, reduce real GDP,
and increase the unemployment rate.

17. An economic theory that estimates the amount of adjustment needed on the exchange rate between
countries in order for the exchange to be equivalent to each currency's purchasing power.
The relative version of PPP is calculated as:
Where:
"S" represents exchange rate of currency 1 to currency 2
"P1" represents the cost of good "x" in currency 1
"P2" represents the cost of good "x" in currency 2
One of the best comparison indicators is the Big Mac Index that
compares the price of the big mac around the world.

18. According to a strict academic definition, a monopoly is a market containing
a single firm. In such instances where a single firm holds monopoly power,
the company will typically be forced to divest its assets. Antimonopoly
regulation protects free markets from being dominated by a single entity.
M O N O P O LY
A type of monopoly that exists as a result of the
high fixed or start-up costs of operating a
business in a particular industry. Because it is
economically sensible to have certain natural
monopolies, governments often regulate those in
operation, ensuring that consumers get a fair
deal.
Natural Monopoly

19. The increase in efficiency of production as the number of goods being produced increases.
Typically, a company that achieves economies of scale lowers the average cost per unit through
increased production since fixed costs are shared over an increased number of goods.
There are two types of economies of scale:
-External economies - the cost per unit depends on the size of the industry, not the firm.
-Internal economies - the cost per unit depends on size of the individual firm.
E C O N O M I E S O F S C A L E

20. M O N E TA R Y P O L I C Y
The actions of a central bank, currency board or other regulatory committee that determine the size and
rate of growth of the money supply, which in turn affects interest rates. Monetary policy is maintained
through actions such as increasing the interest rate, or changing the amount of money banks need to
keep in the vault (bank reserves).

21. The amount charged, expressed as a percentage of principal, by a lender to a borrower for the use
of assets. Interest rates are typically noted on an annual basis, known as the annual percentage
rate (APR). The assets borrowed could include, cash, consumer goods, large assets, such as a vehicle or
building. Interest is essentially a rental, or leasing charge to the borrower, for the asset's use. In the case
of a large asset, like a vehicle or building, the interest rate is sometimes known as the "lease rate". When
the borrower is a low-risk party, they will usually be charged a low interest rate; if the borrower is
considered high risk, the interest rate that they are charged will be higher.
I n t e r e s t R a t e

22. A foreign currency held by central banks and other major financial institutions as a means to pay off
international debt obligations, or to influence their domestic exchange rate. A large percentage of
commodities, such as gold and oil, are usually priced in the reserve currency, causing other countries to
hold this currency to pay for these goods. Holding currency reserves, therefore, minimizes exchange rate
risk, as the purchasing nation will not have to exchange their currency for the current reserve currency in
order to make the purchase.
R E S E R V E C U R R E N C Y

23. Government spending policies that influence macroeconomic conditions. These policies affect tax rates,
interest rates and government spending, in an effort to control the economy.
F I S C A L P O L I C Y

24. TA X E S
Payroll Tax: A tax an employer withholds and/or pays on behalf of their employees based on the wage or
salary of the employee.
Sales Tax: A tax imposed by the government at the point of sale on retail goods and services. It is
collected by the retailer and passed on to the state. Sales tax is based on a percentage of the selling
prices of the goods and services and is set by the state. Technically, consumers pay sales taxes, but
effectively, business pay them since the tax increases consumers costs and causes them to buy less.
Foreign Tax: Income taxes paid to a foreign government on income earned in that country.
Value-Added Tax: A national sales tax collected at each stage of production or consumption of a good.
Depending on the political climate, the taxing authority often exempts certain necessary living items, such
as food and medicine from the tax.

25. A record of all transactions made between one particular country and all other countries during a specified
period of time. BOP compares the difference of the amount of exports and imports, including all financial
exports and imports. A negative balance of payments means that more money is flowing out of the country
than coming in, and vice versa.
B A L A N C E O F PAY M E N T S

26. An economic scenario that occurs when there is an intervention in a given market by a governing body.
The intervention may take the form of price ceilings, price floors or tax subsidies. Market distortions create
market failures, which is not an economically ideal situation.
M A R K E T D I S T O R T I O N

27. An economic term that encompasses a situation where, in any given market, the quantity of a product
demanded by consumers does not equate to the quantity supplied by suppliers. This is a direct result of a
lack of certain economically ideal factors, which prevents equilibrium.
M A R K E T F A I L U R E

28. I N N O VAT I O N
Product Innovation
The development and market introduction of a new, redesigned or substantially improved good or service.
Examples of product innovation by a business might include a
new product's invention; technical specification and quality improvements made to a product; or the
inclusion of new components, materials or desirable functions into an existing product.
Process Innovation
The implementation of a new or significantly improved
production or delivery method. It involves the
development of a new way to produce a product using a
newly developed machine, a new or the use of new
software.

29. Deliberate assumption of above average (but analyzed, measured, and usually hedged) short-
term risk of financial loss, in expectation of above average gain from an
anticipated change in prices. Organized speculation (as conducted through commodity and stock
exchanges) adds capital and liquidity to financial markets, and helps dampen wild fluctuations in prices in
normal times. In times of speculative hysteria or economic/political crises, however,
speculation exacerbates price swings and may swamp usual trading activity. In terms of degree of
risk assumed, speculation (short-term acquisition of assets) falls between investment (long-term acquisition
of assets for income and/or capital appreciation) and gambling (wagering on random outcomes without
acquisition of assets).
