Q

<p>TOTAL REVENUE TEST OF PED </p>

A

<p>If the demand for a good is price elastic and the price falls, then the total revenues of producers will increase (as consumers are highly responsive to the lower price so the % increase in Qd will exceed the % decrease in price).

Q

<p>Tax incidence </p>

A

<p>(Sometimes called tax burden) When an indirect tax is placed on a particular good or group of goods, the incidence, or burden, of the tax is shared by producers and consumers. Buyers will pay a higher price, thus share some of the burden of the tax. But once the tax has been paid to the government, producers end up keeping a lower price, meaning they also share some of the tax burden. The amount of a tax on a particular good paid by consumers is the consumer tax incidence; the amount paid by producers is the producer tax incidence.</p>

<p>The costs to society created by market inefficiency. Mainly used in economics, deadweight loss can be applied to any deficiency caused by an inefficient allocation of resources. Price ceilings (such as price controls and rent controls), price floors (such as minimum wage and living wage laws) and taxation are all said to create deadweight losses. Deadweight loss occurs when supply and - are not in equilibrium. </p>

62
Q

<p>Equilibrium</p>

A

<p>The point where what is expected or planned is equal to what is realised or actually happens</p>

63
Q

<p>Cross Elasticity of Demand (XED)</p>

<p>A measure of the responsiveness of quantity demanded of one good to a change in price of another good. It is measured by dividing the percentage change in quantity demanded of one good by the percentage change in price of the other good. </p>

64
Q

<p>Economic growth</p>

A

<p>It is typically measured by growth in real GDP although this is only a proxy measure because actual GDP can be above or below the productive potential of the economy at a point in time. </p>

Q

<p>Excess demand</p>

A

<p>where demand is greater than supply </p>

66
Q

<p>total sales revenue or turnover minus cost of sales, the direct costs of production.</p>

67
Q

<p>Break even price</p>

A

<p>The break-even price represents the price that is required to cover total costs (both fixed and variable). Total profit at the break-even point is zero. Break-even is only possible if a firm’s prices are higher than its variable costs per unit. If so, then each unit of the product sold will generate some “contribution” toward covering fixed costs.</p>

68
Q

<p>Market Failure</p>

A

<p>Where resources are inefficiently allocated due to imperfections in the working of the market mechanism.
</p>

69
Q

<p>Profit</p>

A

<p>Profit is Revenue minus cost. A business owner expects to earn a “normal” level of profit, otherwise it will not be worth his while to remain in a market. In this regard, profit is a cost of production, because if a minimum profit is not earned a firm will shut down.</p>

70
Q

<p>Opportunity Cost</p>

A

<p>Is the value of the next best alternative foregone when an economic decision is made

72
Q

<p>Economic development</p>

A

<p>Measure of welfare, a measure of well-being. It is usual to measure economic development not just in monetary term, but also in term of other indicators, such as education indicators, health indicators, and social indicators. Look up HDI.</p>

73
Q

<p>Wealth effect</p>

A

<p>the change in consumption following a change in wealth. This could work as an incentive to spend more as people would feel that they are wealthier. Ex: A house that someone owns has increased in value, so the head of the family decides to go on vacation.</p>

74
Q

<p>Market supply curve</p>

A

<p>The supply curve of all producers within the market. In a perfectly competitive market it can be calculated by summing the supply curves of individual producers.</p>

75
Q

<p>Merit good</p>

A

<p>A good which is underprovided by the market mechanism. A demerit good is one which is overprovided by the market mechanism.</p>

76
Q

A

<p>those economically active who are looking for work. Example on the diagram below.</p>

85
Q

Actual increase in in levels of production. Can be represented by a shift of a point of the PPC closer towards the curve. Shifting from point A to point B.

86
Q

Common Access Resources

A

Also known as common pool resources or common property resources, these are resources which have properties similar to public goods in that it is very difficult or impossible to prevent people from using or consuming the resource. Therefore they are vulnerable to overuse/degradation.

87
Q

Entrepreneurship

A

The creativity and innovation an individual puts towards the production of goods and services by combining factors of production and with the willingness to take risks. (Example: Mark Zuckerberg: Facebook)

90
Q

Core inflation

A

A measure of inflation that factors out the changes in the prices of products that tend to experience volatile price swings, (e.g. food and energy prices). This gives policymakers a better indication of long term changes in the price level.

91
Q

Fixed Costs

A

Costs that do not vary with production.

92
Q

Free Good

A

A good that is demanded, but not limited in quantity, thus it is not scarce.
