1Holiday WorkOver the holiday I would like you to get examples of demerit or merit goods…. Take photos of examples… maybe films….Pick one…..Ideas for reducing consumption of demerit goodsOr increasing consumption of merit goodsOr this could be positive and negative externalities.
2Introduction to Market Failure Изъяны Рынка Внешние Эффекты и рыночная эффективность
3Market Failure рыночная неэффективность Definition: Where the market mechanism fails to allocate resources efficiently
4Market FailureSocial Efficiency = where external costs and benefits затраты и выгоды are accounted forAllocative Efficiency = where society produces goods and services at minimum cost that are wanted by consumers WHO GETS THE GOODSTechnical Efficiency = production of goods and services using the minimum amount of resources WITH WHAT ARE GOODS PRODUCEDProductive Efficiency = production of goods and services at lowest factor cost HOW ARE THE GOODS PRODUCED
5Or put simply Markets can function inequitably Markets can function inefficiently
7Market Failure Market Power: Monopolies and oligopolies Collusion Price fixingSupernormal profitsBarriers to entry
8Imperfect Knowledge: Asymmetry of Information Consumers do not have adequate technical knowledgeAdvertising can mislead or mis-informDecisions often based on past experience rather than future knowledge
9Market Failure Goods/Services are Differentiated Branding Designer labels - they cost three times as much but are they three times the quality?Labelling and product informationWhich one is the ‘quality’ item and why?
10Private Goods i.e. goods that can be identified as your possession. You have ‘Property Rights’ права собственности over that good.It is therefore ‘excludable’ i.e. you can prevent other people from using it.
11Tragedy of the Commons Трагедия общих земель Because it is difficult to establish property rights there is the likelihood that this resource will be overused and destroyed.
19Market Failure Public Goods Markets would not provide such goods and services at all!e.g. police, street lighting,Non- excludability неисключительностьPerson paying for the benefit cannot prevent anyone else from also benefiting - the ‘free rider безбилетники problem’A non- excludable good?Would you pay for this?
20Merit Goods & Demerit Goods Consumption of merit goods gives social benefits or imposes social costs.In groups of two, think of examples of each and why….
21Merit Goods nurseries, schools, colleges, universities could all be provided by themarket but would everyonebe able to afford them?Schools: Would you pay if the statedid not provide them?
22Demerit Goods De-Merit Goods Society suffers from the consumption of these goods.Goods and services provided by the market which are not in our best interests! examplesTobacco and alcoholDrugsGambling
23De-merit goodsMerit goods are ‘good’ for you. De-merit goods are thought to be ‘bad’ for you
29Activity 5 minutesHow can a government limit the consumption of demerit goods?How can the consumption of merit goods be encouraged?Think of as many ways.
30Market Failure External Costs and Benefits External or social costs The cost of an economic decision to a third partyExternal benefitsThe benefits to a third party as a result of a decision by another party
31Market Failure External Costs e.g. Pollution traffic congestion, environmental degradationdepletion of the ozone layer
32One ton of industrial wastes per resident in Pavlodar oblast Tengri News March 2013
35Marginal Cost Curve Marginal cost curves are U shaped. The cost of producing the extra item is considered to fall at firstthen it will riseThis is because of economies and then diseconomies of scale
36Marginal Benefit Curve Downward slopingI.e. the benefit from consuming the extra unit of output will declineI.e. the value the consumer puts on the extra good will fall and the quantity increases.
