Functions of the Price Mechanism I A Level and IB Economics
Summary
TLDRThis video script delves into the functions of the price mechanism, highlighting its role in a mixed economy. It explains how prices ration scarce resources, especially when demand exceeds supply, and serve as signals to producers about resource requirements. The script also discusses the importance of the price mechanism's signaling function in guiding production decisions and adjusting to market changes, using examples such as the falling footwear prices in the UK due to global competition and cost reductions.
Takeaways
- đ Adam Smith introduced the concept of the 'invisible hand' of the price mechanism, suggesting that market competition driven by self-interest can allocate resources in society's best interests.
- đ The video discusses differing views on the role of government in the economy, with some advocating for minimal intervention and others arguing for state intervention to address market failures.
- đ The price mechanism has two key functions: allocation and signaling, which are essential for the operation of a mixed economy like the UK.
- đïž The rationing function of prices is seen when demand exceeds supply, leading to higher prices that allocate resources to those willing and able to pay.
- đ Prices serve a signaling function, providing information to producers about where resources are needed and adjusting production accordingly.
- đ The price mechanism changes incentive structures for both consumers and businesses, influencing their economic behavior based on price signals.
- đ Examples of rationing include high food prices affecting purchasing power and the high cost of renting as a way to ration demand for housing.
- đïž Auctions and event tickets illustrate how prices can be used to ration access to scarce goods or services.
- đ The fall in the average price index for footwear products in the UK over the last decade is attributed to increased competition, global imports, and retail competition.
- đ The impact of global competition, particularly from countries like Thailand, China, and Bangladesh, has driven down the prices of goods like footwear.
- đ° The price of oil's decline has had significant signaling effects on the market for shale oil and gas, as well as on the renewable energy industry.
- đ Share prices and interest rates are examples of how the price mechanism sends signals about current and future profitability and borrowing costs.
Q & A
What is the 'invisible hand' mentioned in the script?
-The 'invisible hand' is a term coined by Adam Smith to describe the self-regulating nature of the marketplace, where individual self-interest leads to the allocation of resources in a way that often benefits society as a whole.
What are the two key functions of the price mechanism discussed in the video?
-The two key functions of the price mechanism are allocation and signaling. Allocation refers to the distribution of scarce resources among competing users, while signaling informs producers about where resources are needed and where they are not.
How does the price mechanism ration resources when demand exceeds supply?
-When demand exceeds supply, the price mechanism rations resources by increasing prices, which makes only those with the willingness and ability to pay able to purchase the product.
What is the signaling function of the price mechanism, and why is it important?
-The signaling function of the price mechanism is crucial because it communicates to producers where resources are needed and where they are not. Prices rise and fall to reflect scarcity and surpluses, signaling to suppliers to adjust production accordingly.
Can you give an example of how prices signal to producers to adjust production?
-An example is when there is a rise in coffee prices, signaling high demand from consumers. This may prompt suppliers to expand coffee production to meet the increased demand.
What is the role of the price mechanism in a mixed economy like the UK?
-In a mixed economy like the UK, the price mechanism operates alongside private sector and state activity to help allocate resources and send signals about resource needs, with minimal government intervention where possible.
How does the price of a product in an auction serve as a rationing function?
-In an auction, the high cost of a product serves as a rationing function by allowing only those willing to pay the highest price to obtain the product, effectively allocating the scarce resource to the highest bidder.
What are some factors that can cause a sustained fall in the average price index of a product, as seen in the UK footwear market?
-Factors such as increased competition, imports of cheaper products, intense retail competition, falling input costs, and a strong exchange rate can contribute to a sustained fall in the average price index of a product.
How does the price mechanism affect consumers' purchasing behavior in the case of footwear prices falling?
-When footwear prices fall, it signals to consumers that it is cheaper to buy new shoes rather than repair old ones, potentially leading to increased consumption and a shift in purchasing behavior.
What signals do falling oil prices send to the market, and what are the potential effects?
-Falling oil prices signal a potential surplus in the market. This can lead to a reduction in production by some suppliers, especially in the shale oil and gas industry, and may also affect investment in renewable energy.
How do interest rates on loans act as a signaling function in the economy?
-Interest rates on loans signal the cost of borrowing to potential buyers. Lower interest rates can encourage borrowing and spending, while higher rates may deter it, thus influencing economic activity.
Outlines
đ The Price Mechanism: Allocation and Signaling
This paragraph introduces the concept of the price mechanism and its functions, as described by Adam Smith, the 'invisible hand' that guides resource allocation in a market economy. It discusses the debate between free market economists who advocate for minimal government intervention and those who believe in state intervention due to market failures. The key functions highlighted are allocation, which involves rationing scarce resources among users, and signaling, which communicates information to producers about resource requirements. The paragraph uses examples such as food prices, rent costs, and event tickets to illustrate how prices ration resources and discusses the importance of the signaling function in guiding production and consumption decisions.
đ The Impact of the Price Mechanism on Footwear Prices
The second paragraph delves into the practical application of the price mechanism, focusing on the footwear industry in the UK. It explains how a sustained fall in the average price index over the past decade can be attributed to increased competition from imports, particularly from countries like Thailand, China, and Bangladesh. The paragraph also considers the impact of retail competition, cost of inputs, and a strong exchange rate on the price of footwear. The deflation in the market sends signals to both consumers, who now opt to buy new shoes instead of repairing old ones, and suppliers, who must adapt to a highly competitive retail environment. The summary concludes by emphasizing the decentralized nature of the price mechanism and its effectiveness in resource allocation and rationing.

hi there welcome to a short topic video
on the functions of the price mechanism
many years ago adam smith one of the
founding fathers of economics
described the invisible hand of the
price mechanism
which the hidden hand of the market
operating in competitive conditions to
the pursuit of self-interest
allocated resources largely in society's
best interests
well of course there are still plenty of
free market economists out there who
believe that the market should be left
to allocate resources with minimal
government intervention
others of course believe that market
failures are endemic and persistent and
important and require intervention by
the state
but in this short video it's going to
look at the key functions of the price
mechanism
uk is a mixed economy we have a mix of
private sector and state activity
most economies of course are mixed
economies
but what are the key functions of the
price mechanism allocation
lasting signaling
so essentially the bias mechanism helps
to allocate scarce resources amongst
competing users
one of the key functions of the price
mechanisms is to ration we'll have a
look at that in a second but prices in
the market serve to ration resources
when particularly when demand outstrips
supply
prices also send important signals they
send information to producers about
where resources are required and where
they're not and the price mechanism is
an important vehicle for changing the
incentive structures faced by both
consumers and businesses so let's look
at two of these in a little bit more
detail
the rationing function is where prices
serve to ration resources when demand is
greater than supply
so for example when there's a shortage
of a product the price is bid up and
essentially leaving only those with the
willingness and the ability to pay to
purchase the product
so lots of good examples of food prices
of course affecting people's real
purchasing power
the high cost of renting
is a way of rationing excess demand for
vented accommodation particularly in our
major cities
auctions of course are a way of
stripping out those who are willing to
pay different prices particularly online
auctions
tickets for big major events such as
leicester city's last home game having
won the premiership or a tutor to eu
revision conference you know tickets for
a big event
clearly demand that strip supply and
perhaps the the shadow market creates a
a rationing function there
in our diagram i'm showing you an inward
shift of the supply curve that forces
the price up and of course that rations
demand because there are some people who
don't have the effective demand to be
able to purchase the product
the signaling function i think is
probably the most important aspect of
the price mechanism
so what does it mean well prices perform
a signaling function so prices are just
to demonstrate where resources are
required and they rise and fall
to reflect scarcity and surpluses
so for example when prices are rising
maybe that's because of high demand from
consumers that's a signal to suppliers
perhaps to expand production to meet
demand
if there's too much supply in the market
prices tend to fall
and that helps to eliminate the surplus
by allowing consumers to buy more and
also by incentivizing producers maybe to
send to supply less
lots and lots of good examples of where
the price mechanism
sends signals so coffee farmers
if there's a fall in the world price of
coffee
it sends a signal to some of them they
might be better off
ripping up their coffee plantations and
starting to produce other products
instead
the fall in the price of oil in the last
12 months or so has uh caused some
significant signaling effects in the
market for both shale oil and gas in the
united states and canada and elsewhere
but also the
profit motive in the renewable energy
industry
share prices of course send important
signals about current and future
profitability interest rates on loans
send a signal to potential buyers as
well
so the price mechanism
is largely built on the idea of the
signaling function it's it's really
important
here's a good example of prices in
action
this is an index of footwear products in
the uk so things like sandals and shoes
and trainers etc and actually over the
last uh 10 years or so there's been a
quite a sustained fall in the average
price index for footwear products in the
uk index has fallen from above 107 in
2003 to about 80 84 in 2014 so a
significant fall
why has that happened well in part
because of increased competition the
imports of cheap footwear from the likes
of thailand and china and bangladesh
indonesia
so global competition has driven prices
down
we've also seen intense retail
competition on the high street uh
particularly in the deep discount sports
sectors such as sports direct and and
jjb sports what have you
and of course increasingly people can
bar and line
uh the cost of inputs might have fallen
so for example the cost of leather or
the cost of manufacturing might have
gone down
increasing supply
and it could well be the case that a
relatively strong exchange rate also
makes imports cheaper
so a combination of supply and demand
factors
is causing footwear prices to fall
there's genuine deflation in the market
well that sends a signal to consumers
many people now are buying you know
cheap trainers and in fact oftentimes
they'll just buy another pair when it
comes to repair it's cheaper to buy
another pair than it is to to repair
them it sends a sql to consumers and of
course it sends important signals to to
suppliers in a very competitive
retail environment
so we've looked at the functions of the
price mechanism the key things to take
away from this are that the price
mechanism is a decentralized
machine
often works incredibly well
and the key to it is the way in which
signaling
and allocation of resources happens and
the rationing function through the price
mechanism
hopefully that was useful good luck in
