Transcripts - Price mechanism
EconomicsPrice MechanismThe invisible hand – the workings of the pricemechanism Adam Smith, one of the Founding Fathers of economics famously wrote of the “invisible hand of the price mechanism”. He described how the invisible or hidden hand of the market operated in a competitive market through the pursuit of self- interest to allocate resources in society’s best interest. This remains the central view of all free-market economists, i.e. those who believe in the virtues of a free-market economy with minimal government intervention. The price mechanism is a term used to describe the means by which the many millions of decisions taken each day by consumers and businesses interact to determine the allocation of scarce resources between competing uses. This is the essence of economics! Adam SmithThe price mechanism plays three important functions in any market-based economic system:The signalling function
The price of digital printing is coming down – this will have an effect on the demand for substitute forms of image printing. How will traditional photo imaging retailers respond?Firstly, prices perform a signalling function. This means that market prices will adjust to demonstratewhere resources are required, and where they are not.Prices rise and fall to reflect scarcities and surpluses. So, for example, if market prices are risingbecause of high and rising demand from consumers, this is a signal to suppliers to expand theirproduction to meet the higher demand.Consider the left hand diagram on the next page. The demand for computer games increases and as aresult, producers stand to earn higher revenues and profits from selling more games at a higher priceper unit. So an outward shift of demand ought to lead to an expansion along the market supply curve.
In the second example on the right, an increase in market supply causes a fall in the relative prices ofdigital cameras and prompts an expansion along the market demand curveConversely, a rise in the costs of production will induce suppliers to decrease supply, while consumerswill react to the resulting higher price by reducing demand for the good or services.The transmission of preferencesThrough the signalling function, consumers are able through their expression of preferences to sendimportant information to producers about the changing nature of our needs and wants. Whendemand is strong, higher market prices act as an incentive to raise output (production) because thesupplier stands to make a higher profit. When demand is weak, then the market supply contracts. Weare assuming here that producers do actually respond to these price signals!One of the features of a free market economy is that decision-making in the market is decentralised inother words, the market responds to the individual decisions of millions of consumers and producers,i.e. there is no single body responsible for deciding what is to be produced and in what quantities. Thisis a remarkable feature of an organic market system.The rationing functionPrices serve to ration scarce resources when demand in a market outstrips supply. When there is
a shortageof a product, the price is bid up – leaving only those with sufficient willingness and abilityto pay with the effective demand necessary to purchase the product. Be it the demand for ticketsamong England supporters for the 2006 World Cup or the demand for a rare antique, the market priceacts a rationing device to equate demand with supply.The prices for using the M6 Toll Road are a good example of the rationing function of the pricemechanism. A toll road can exclude those drivers and vehicles that are not willing or able to pay thecurrent toll charge. In this sense, motorists and road haulage businesses and other road users arepaying for the right to use the road, road space has a market price instead of being regarded assomething of a free good. The current charges are below:Prices on the M6 Toll Road Day NightJune 2006 (06:00 - 23:00) (23:00 - 06:00) Class 1 (e.g. motorbike) £2.50 £1.50 Class 2 (e.g. car) £3.50 £2.50 Class 3 (e.g. car & trailer) £7 £6 Class 4 (e.g. van/coach) £7 £6 Class 5 (e.g. HGV) £7 £6What would happen if the day-time charges increased to £5 for cars?The growing popularity of auctions as a means of allocating resources is worth considering as a meansof allocating resources and clearing a market. The phenomenal success of EBAY is testimony to thepower of the auction process as a rationing and market clearing mechanism as internet usage hasgrown.The price mechanism is the only allocative mechanism solving the economic problem in a free marketeconomy. However, most modern economies are mixed economies, comprising not only a marketsector, but also a non-market sector, where the government (or state) uses the planningmechanism to provide public goods and services such as police, roads and merit goods such aseducation, libraries and health.In a state run command economy, the price mechanism plays little or no active role in the allocationof resources. Instead government planning directs resources to where the state thinks there is greatestneed. The reality is that state planning has more or less failed as a means of deciding what to produce,how much to produce, how to produce and for whom. Following the collapse of communism in the late1980s and early 1990s, the market-based economy is now the dominant economic system – even thoughwe are increasingly aware of imperfections in the operation of the market – i.e. the causes andconsequences of market failure.Prices and incentives • Incentives matter enormously in our study of microeconomics, markets and instances of market failure. For competitive markets to work efficiently all economic agents (i.e. consumers and producers) must respond to appropriate price signals in the market. • Market failure occurs when the signaling and incentive function of the price mechanism fails to operate optimally leading to a loss of economic and social welfare. For example, the market may fail to take into account the external costs and benefits arising from production and consumption. Consumer preferences for goods and services may be based on imperfect information on the costs and benefits of a particular decision to buy and consume a product. Our individual preferences may also be distorted and shaped by the effects of persuasive
advertising and marketing to create artificial wants and needs.Government intervention in the marketOften the incentives that consumers and producers have can be changed by governmentintervention in markets. For example a change in relative prices brought about by the introductionof government subsidies and taxation.Suppose for example that the government decides to introduce a new tax on aviation fuel in a bid toreduce some of the negative externalities created by the air transport industry. • How will airlines respond? a. Will they pass on the tax to consumers? b. Can they absorb the tax and seek cost-savings elsewhere in their operations? • If the tax raises price for air travellers, will they change their behaviour in the market? • Is an aviation tax the most effective way of controlling pollution? Or could incentives for producers and behaviour by consumers wanting to travel by air be changed through other more effective and efficient means?
Agents may not always respond to incentives in the manner in which textbook economics suggests.The “law of unintended consequences” encapsulates the idea that government policy interventionscan often be misguided of have unintended consequences! See the revision focus article on governmentfailure.
AS Markets & Market SystemsTheory of SupplyIn this chapter we turn our attention to the decisions that producers make about how much of aproduct to supply to a market at any given price. Once we have understood the basics of supply, wecan they put supply and demand together to consider the determination of equilibrium prices in amarket.Definition of SupplySupply is defined as the quantity of a product that a producer is willing and able to supply onto themarket at a given price in a given time period.Note: Throughout this study companion, the terms firm, business, producer and seller have the samemeaning.The basic law of supply is that as the price of a commodity rises, so producers expand their supplyonto the market. A supply curve shows a relationship between price and quantity a firm is willing andable to sell.
A supply curve is drawn assuming ceteris paribus - ie that all factors influencing supply are being heldconstant except price. If the price of the good varies, we move along a supply curve. In the diagramabove, as the price rises from P1 to P2 there is an expansion of supply. If the market price falls fromP1 to P3 there would be a contraction of supply in the market. Businesses are responding to pricesignals when making their output decisions.Explaining the Law of SupplyThere are three main reasons why supply curves for most products are drawn as sloping upwards fromleft to right giving a positive relationship between the market price and quantity supplied: 1. The profit motive: When the market price rises (for example after an increase in consumer demand), it becomes more profitable for businesses to increase their output. Higher prices send signals to firms that they can increase their profits by satisfying demand in the market. 2. Production and costs: When output expands, a firm’s production costs rise, therefore a higher price is needed to justify the extra output and cover these extra costs of production. 3. New entrants coming into the market: Higher prices may create an incentive for other businesses to enter the market leading to an increase in supply.Shifts in the Supply CurveThe supply curve can shift position. If the supply curve shifts to the right (from S1 to S2) this is anincrease in supply; more is provided for sale at each price. If the supply curve moves inwards from S1
to S3, there is a decrease in supply meaning that less will be supplied at each price.Changes in the costs of productionLower costs of production mean that a business can supply more at each price. For example amagazine publishing company might see a reduction in the cost of its imported paper and inks. A carmanufacturer might benefit from a stronger exchange rate because the cost of components and newtechnology bought from overseas becomes lower. These cost savings can then be passed throughthe supply chain to wholesalers and retailers and may result in lower market prices for consumers.Conversely, if the costs of production increase, for example following a rise in the price of rawmaterials or a firm having to pay higher wages to its workers, then businesses cannot supply as much atthe same price and this will cause an inward shift of the supply curve.A fall in the exchange rate causes an increase in the prices of imported components and raw materialsand will (other factors remaining constant) lead to a decrease in supply in a number of differentmarkets and industries. For example if the pounds falls by 10% against the Euro, then it becomes moreexpensive for British car manufacturers to import their rubber and glass from Western Europeansuppliers, and higher prices for paints imported from Eastern Europe.Changes in production technology
Production technologies can change quickly and in industries where technological change is rapid wesee increases in supply and lower prices for the consumer.Government taxes and subsidies
Changes in climateFor commodities such as coffee, oranges and wheat, the effect of climatic conditions can exert agreat influence on market supply. Favorable weather will produce a bumper harvest and will increasesupply. Unfavorable weather conditions will lead to a poorer harvest, lower yields and therefore adecrease in supply.Changes in climate can therefore have an effect on prices for agricultural goods such as coffee, tea andcocoa. Because these commodities are often used as ingredients in the production of other products, achange in the supply of one can affect the supply and price of another product. Higher coffee prices forexample can lead to an increase in the price of coffee-flavored cakes. And higher banana prices as wesee in the article below, will feed through to increased prices for banana smoothies in shops and cafes.Cyclone destroys the Australian banana crop and sends prices soaringCyclone Larry has devastated Australias banana industry, destroying fruit worth $300 million andleaving up to 4,000 people out of work. Australians now face a shortage of bananas and likely pricerises after the cyclone tore through the heart of the nations biggest growing region. Queenslandproduces about 95 per cent of Australias bananas. The storm ruined 200,000 tones of fruit and marketsupply shortages will be severe because Australia does not allow banana imports because of the bio-security risks in doing so. Bananas are grown throughout the year in north Queensland, with the fruithaving a growing cycle of around two months.
Source: Adapted from news reports, April 2006Change in the prices of a substitute in productionA substitute in production is a product that could have been produced using the same resources. Takethe example of barley. An increase in the price of wheat makes wheat growing more financiallyattractive. The profit motive may cause farmers to grow more wheat rather than barley.The number of producers in the market and their objectivesThe number of sellers (businesses) in an industry affects market supply. When new businesses enter amarket, supply increases causing downward pressure on price.Competitive SupplyGoods and services in competitive supply are alternative products that a business could make with itsfactor resources of land, labour and capital. For example a farmer can plant potatoes or maize. Farmers can change their crops if there are sizeable changes in market prices and if expectations of future price movements also change.
