Q

Ceteris Paribus

A

Ceteris Paribus, a Latin phrase, roughly means “holding other things constant”. This term is most widely used in economics and finance as a shorthand indication of the effect of one economic variable on another, keeping all other variables constant that could render an effect on the second variable.

Q

Variable Cost Ratio

A

The variable cost ratio is an expression of a company’s variable production costs as a percentage of sales, calculated as variable costs divided by total revenues. It compares costs that change with levels of production to the amount of revenues generated by production. This contrasts with fixed costs that remain constant regardless of production levels.

Q

Correlation Coefficient

A

The correlation coefficient is a measure that determines the degree to which two variables’ movements are associated. The range of values for the correlation coefficient is -1.0 to 1.0. If a calculated correlation is greater than 1.0 or less than -1.0, a mistake has been made. A correlation of -1.0 indicates a perfect negative correlation, while a correlation of 1.0 indicates a perfect positive correlation.

Random Variable

A

A random variable is a variable whose value is unknown or a function that assigns values to each of an experiment’s outcomes. Random variables are often designated by letters and can be classified as discrete, which are variables that have specific values, or continuous, which are variables that can have values within a continuous range.

Q

Inelastic Demand

A

Inelastic is an economic term used to describe the situation in which the quantity demanded or supplied of a good or service is unaffected when the price of that good or service changes. Inelastic means when the price goes up, consumers’ buying habits stay about the same, and when the price goes down, consumers’ purchasing habits also remain unchanged.

Q

Income

A

The amount of profit, interest, rent, labour earnings and other payments (including transfers from the government) received, net of taxes paid, measured over a period of time such as a year. Your income is the maximum amount that you could consume and leave your wealth unchanged. It is also referred to as disposable income, to distinguish it from pre-tax income that is not all available to be spent.

Q

Causality

A

A direction from cause to effect. A variable is said to be causal if a change in this variable produces a change in (“causes”) another. While a correlation is simply an assessment that two things move together, causality establishes the mechanism accounting for the association: causality is therefore a more restrictive concept.

Q

Natural Experiment

A

An empirical study exploiting naturally occurring statistical controls in which researchers do not have the ability to assign participants to treatment and control groups, as in the case in conventional experiments. Instead, differences in law, policy, weather, or other events can offer the opportunity to analyse populations as if they had been part of the experiment. The validity of such studies depends on the premise that the assignment of subjects to the naturally occurring treatment and control groups can be plausible argued to be random.

Lorenz Curve

A

A graphical representation of inequality of some quantity such as wealth or income. Individuals are arranged in ascending order by how much of this quantity they have: the cumulative share of the total is then plotted against the cumulative share of the population. For complete equality of income, for example, the Lorenz curve would be a straight line with a slope of one; the extent to which the curve falls below this perfect equality line is a measure of inequality.

Economies of scale

A

These occur when doubling all the inputs to a production process more than doubles the output. The shape of a firm’s long-run average cost curve depends both on returns to scale in production and the effect of scale on prices it pays for its inputs. Also known as increasing returns to scale in production.

96
Q

Willingness to Pay (WTP)

110
Q

External Effect (externality)

122
Q

Fiscal Multiplier

A

The total (direct and indirect) change in the output caused by an initial change in government spending.

123
Q

Marginal Propensity to Consume

A

The change in consumption when disposable income changes by one unit.

124
Q

Marginal Propensity to Import

A

The change in total imports associated with a change in total income.

125
Q

Consumption Function (aggregate)

A

An equation that shows how consumption spending in the economy as a whole depends on other variables: for example, in a multiplier model, the other variables are current disposable income and autonomous consumption.

126
Q

Investment Function

A

An equation that shows how the investment spending in the economy as a whole depends on other variables, namely, the interest rate and profit expectations.

127
Q

Goods Market Equilibrium

A

The point at which output equals the aggregate demand for goods produced in the home economy. The economy will continue producing at this output level unless something changes spending behaviour.

128
Q

Autonomous Consumption

A

Consumption that is independent of income.

129
Q

Autonomous Demand

A

Components of aggregate demand that are independent of current income.

130
Q

Target Wealth

A

Target wealth is the level of wealth that the household aims to hold, based on its economic goals (or preferences) and expectations. We assume that households try to maintain this level of wealth in the face of changes in their economic situation , as long as it is possible to do so.

131
Q

A

A record of assets, liabilities and net worth of an economic actor such as a household, bank, firm or government.

132
Q

A

Characteristics of the tax and transfer system in an economy that have the effect of offsetting an expansion or contraction of the economy.

134
Q

Fiscal Stimulus

A

The use by the government of fiscal policy (via a combination of tax cuts and spending increases) with the intention of increasing aggregate demand.

135
Q

Paradox of Thrift

A

The paradox is that if a single individual consumes less, her savings will increase; but if everyone consumes less, the result may be lower rather than higher savings overall. The attempt to increase saving is thwarted if an increase in the saving rate is unmatched by an increase in investment (or other source of aggregate demand such as government spending on goods and services). The outcome is a reduction in aggregate demand and lower output so that actual levels of saving do not increase.

136
Q

Government Budget Balance

A

The excess of government purchases of goods and services plus interest payments and transfers including pensions over tax and other forms of revenue.

137
Q

Government Budget Deficit

A

When the government budget balance is negative.

138
Q

Government Budget Surplus

A

When the government budget balance is positive.

139
Q

Primary Deficit

A

The government deficit (its revenue minus its expenditure) excluding interest payments to debt.

140
Q

Government Debt

A

The sum of all the bonds the government has sold over the years to finance its deficits, minus the ones that have matured.

141
Q

Supply Side (aggregate economy)

A

How labour and capital are used to produce goods and services. It uses the labour market model (also referred to as the wage curve and profit curve model).

142
Q

Demand Side (aggregate economy)

A

How spending decisions generate demand for goods and services, and as a result, employment and output. It uses the multiplier model.

143
Q

Business Cycle

A

Alternating periods of positive and negative growth rates. The economy goes from boom to recession and back to boom.

144
Q

Long Run (model)

A

The term does not refer to a period of time, but instead to what is exogenous. A long-run cost curve, for example, refers to costs when the firm can fully adjust all of the inputs including its capital goods; but technology and the economy’s institutions are exogenous.

145
Q

Medium Run (model)

A

The term does not refer to a period of time, but instead to what is exogenous: capital stock, technology and institutions are exogenous in the medium run.

146
Q

Short Run (model)

A

The term does not refer to a period of time, but instead what is exogenous: prices, wages, capital stock, technology and institutions are exogenous.

147
Q

Globalisation

A

A process by which the economics of the world become increasingly integrated by the freer flow across national boundaries of goods, investment, finance and to a lesser extent labour. The term is sometimes applied more broadly to include ideas, culture, and even the spread of epidemic diseases.

148
Q

Hyperglobalisation

A

An extreme (and so far hypothetical) type of globalisation in which there is virtually no barrier to the free flows of goods, services and capital.

149
Q

Specialisation

A

This takes place when a country or some other entity produces a more narrow range of goods and services than it consumes, acquiring the goods and services that it does not produce by trade.

150
Q

Comparative Advantage

A

A country has comparative advantage compared to some other country in the production of the good for which it has the greatest absolute advantage, or least productivity disadvantage.

151
Q

Price Gap

A

Difference in the price of a good in the exporting country and the importing country. It takes into account transportation costs and trade taxes. When global markets are in competitive equilibrium, these differences will be entirely due to trade costs.

152
Q

Trade Costs

A

The transport costs, tariffs or other factors incurred in trading between markets in two countries that mean that, for affected goods, the Law of one price will not hold across each market.

153
Q

Arbitrage

A

The practice of buying a good at a low price in a market to sell it at a higher price in another. Traders engaging in arbitrage take advantage of the price difference for the same good between two countries or regions. As long as the trade costs are lower than the price gap, they make a profit.

154
Q

Globalisation I and II

A

Two separate periods of increasing global integration. Globalisation I extended from before 1870 until the outbreak of the first world war in 1914. Globalisation II extended from the end of the second world war into the 21st Century.

155
Q

Tariff

A

A tariff is a tax on a good imported into a country.

156
Q

Current Account

A

The sum of all payments made to a country minus all payments made by the country.

157
Q

Current Account Deficit

A

The excess of the value of a country’s imports over the combined value of its exports plus its net earnings from assets abroad.

158
Q

Current Account Surplus

A

The excess of the combined value of its exports and net earnings from assets abroad over the value of its imports.

159
Q

Net Capital Flows

A

The borrowing and lending tracked by the current account.

160
Q

Balance of Payments

A

This records the sources and uses of foreign exchange.

161
Q

Gains from Exchange

A

The benefits that each of two or more people gain from a transaction.

162
Q

Foreign Direct Investment (FDI)

A

Ownership and substantial control over assets in a foreign country.

163
Q

Foreign Portfolio Investment

A

The acquisition of bonds or shares in a foreign country where the holdings of the foreign assets are not sufficiently great to give the owner substantial control over the owned entity. Foreign direct investment by contrast entails ownership and substantial control over the owned assets.

164
Q

Economics of Agglomeration

A

The cost reductions that firms may enjoy when they are located close to times in the same or related industries.

165
Q

Learning by Doing

A

This occurs when the output per unit of inputs declines with greater experience in producing a good or service.

166
Q

Infant Industries

A

A relatively new industrial sector in a country that has relatively high costs, because the recent establishment means that it has few benefits from learning by doing, its small size deprives it of economies of scale, or a lack of similar firms means that it does not benefit from economies of agglomeration. Temporary tariff protection of an infant industry may increase the productivity of the economy in the long run.

167
Q

Opportunity Cost

A

When taking an action A means forgoing the opportunity of the next best alternative, B, the opportunity cost of A is the net benefit of action B.

168
Q

Feasible Frontier

A

The feasible frontier is made up of points, each of which indicates for a given feasible quantity of one good, the maximum feasible quantity of the other.

169
Q

Feasible Set

A

All the combinations of things under consideration that the decision maker could choose given the economic, physical or other constraints he or she faces.
