How does the price mechanism work if the price is too high?
A signal is sent to producers that the price is too high, this can be seen through empty tables, fully stocked shelves etc. They are given an incentive to lower their prices, the supply and demand are now at a perfect equilibrium.
29
How does the price mechanism work if the price is too low
A signal is sent to producers, seen by competition between buyers, long queues or huge waiting lists. Producers will raise their price, supply and demand are now at a perfect equilibrium
30
What are the four functions of the price mechanism
Allocate recourses effectively by creating equilibrium, demand is now at the same level as supply (4)
Rationing excess supply/ demand by encouraging or discouraging consumption, raising the price lowers demand, lowering the price raises demand (3)
Sending a signal to producers that prices are too high/ low (1)
Incentivise to change price and increase profit (2)

Demand is price elastic and the good is a normal luxury
93
What does it mean if YED is less than one?
Demand is inelastic normal necessity
94
What is PED useful for?
Useful for pricing decisions to increase total revenue, if price is elastic and they know it is going to fall in the near future, they need to increase employment, output and stocks
95
What is the use of PES?
Find ways to make supply price elastic by increasing the effectiveness of the PSSST factors
96
Why is XED useful?
Pricing decisions- if there are two compliment goods for example printers and printer ink, reduce the price of printers so people buy one, they will need printer ink so increase the price of that and make more profit
Substitutes - cut the price of your substitute, if they cut their price follow their lead. Compete on non price factors to make yours and your substitutes good less similar- avoid price wars. Be prepared to increase output if substitutes raises price, have less output if substitute lowers price
97
Why is YED useful?
Useful for planning for recessions and booms e.g if producing a normal good and there is a boom increase price, employment, output and stocks
98
What are the limitations of using price elasticity to make decisions?
These figures are only estimates based off data collected through surveys
Some businesses base these figures off data based off competitors and past data which is assuming cetris parabus which is inaccurate
PED varies along the demand curve

Any impact on third parties e.g environment as a result of production
150
How do we calculate social cost?
Private costs + external costs
151
What is the supply curve equal to?
Private costs + external costs however in an allocatively efficient market, we assume there are no external costs
152
What is an individual benefit and what does it abbreviate to?
MPB and it is the benefit the consumer gets from consuming a product
153

The increased benefit consumers get per extra unit consumed
154
How do we calculate social benefits?
Individual benefits + external costs/ benefits as a result of consumption
155

163
What is market failure?
When the free market fails to allocate resources at the socially optimum level of output
164
What are the causes of market failure (6)
Positive/ negative externalities being ignored by producers and consumers as producers are profit maximisers and consumers are utility maximisers both are acting out of their own self interest
Information failure around merit/ demerit goods
Free rider problem around public goods
Overproduction of common access recourses
Income inequality- at what point does it become unfair?
Monopoly power- barriers to entry for other firms, the firm at the top has the power to charge unfairly high prices
Factor immobility- supply unable to increase given an increase in demand
165
What is a negative externality?
Costs on a third party as a result of the actions of a separate agent
166
Examples of negative externalities as a result of production?
Air pollution, recourses depletion, resource degradation, deforestation
167
What is resource degradation
If recourses are dumped and this causes further damage for example in the sea
168
What is resource deprecation?
Using up resources to the extent that there is none left for future generations
169
How do social costs affect equilibrium?
If production then supply curve shifts upwards, if consumption then demand curve shifts down, markets will continue at original equilibrium so true allocative efficiency is not reached
170
What is the result of social costs not being taken into account?
Over production + over consumption
Supply: price too low
Demand: price too high
Mis allocation of recourses
171
Examples of negative externalities in consumption

Benefits to third parties as a result of the actions of a separate agent
175
Examples of positive externalities in consumption?
Vaccines (less chance of others getting ill)
Education (higher income can pay more tax benefit society)
Gyms + healthy food ( higher productivity at work)
176
How do positive externalities in consumption affect allocative efficiency?
Demand shifts outwards but markets continue to operate at private optimum
177
How do we calculate dead weight loss of positive externalities of consumption?
Old equilibrium, same point on original demand curve, new equilibrium
178
What are the problems with ignoring positive externalities?
Under production/ consumption and mis allocation of recourses, price is too high
179
Examples of positive externalities in production?
In work training- other companies can poach higher skilled workers
New technology can be copied - no R&D costs (research and development)
180

183
Definition of merit goods?
Goods which are deemed to be more beneficial to society than people realise
184
What is information failure?

185
What is asymmetric information?
One party in a transaction having more information than another party
186
Reasons for incorrect consumption of merit/ demerit goods?
Information failure and asymmetric information
187
What are demerit goods?
Goods which are more harmful to society than people realise
188
What are public goods?
Goods which are non excludable and non rivalry
189
What is non excludable?
No price can be charged for the good
190
What is non rivalry?
The quantity of the good doesn’t diminish under consumption
191
Why may a good be non excludable?
The benefits of consuming a good cannot be confined to the individual who has paid
No efficient way of charging
192
Issues with public goods?
Causes free rider problem- means there is no private motive to supply (missing market)
193
What is a quasi public good?
Sometimes shows characteristics of public goods, sometimes private
194
What is a club good?
Rival but non excludable
195
What is a common resource?
Non excludable but rival, natural recourses over which no private ownership has been established
196
What is the tragedy of the commons?
Private producers acting out of self interest and using up so much that it leads to a depletion of these recourses
197
Examples of common recourses?
Anything in the sea or forests
198
Why might private producers keep taking common recourses even when they can see depletion is happening
Profit motive
If one producer stops and all others continue, only the one who stops loses out, unlikely to do this
199
What is the tragedy of the commons an example of?
A negative externality of production
200
What is government failure?
When the costs of intervention outweigh the benefits
201
What is the result of government failure?
Worsening of the allocation of scarce resources- harming social welfare
202
What are the four causes of government failure?
Information failure, costs of intervention, unintended consequences, regulatory capture
203
Describe information failure?
Politicians are not always experts. Most externalities are very difficult to value, therefore the policy could be too strict or too loose
204
Describe intervention costs?
Admin + enforcement of the policy itself, for example intervention buying, opportunity cost + fairness to the taxpayer has to be considered
205
Describe regulatory capture
If the regulator is trying to control monopoly power, the CEO may influence the regulator and they may end up helping the firm instead of the society
206
Describe unintended consequences
Black markets may arise
Impact on low income families (e.g taxes and minimum prices increase price)
Impact on firms (may become too reliant on subsidies)
Indirect tax or minimum wage (price floor) may cause unemployment
207
How can an indirect tax help to solve market failure?
Increases cost of production (also increases price)
Internalises externality
Solves overconsumption/ production
Gains allocative efficiency + gov rev
208
How do we show an indirect tax correcting market failure in production?
Draw an arrow from the MPC curve to the MSC curve
209
How do we show an indirect tax correcting market failure in consumption?
Draw a second supply curve shifted upwards
The point where it meets the original demand curve should be the same quantity as Qstar
210
Why is price inelastic demand a problem when using indirect tax to solve market faliure?
If there is no change in quantity, the size of the externality stays the same or does not change much, the tax is ineffective, one reason for this could be addiction
211
Why is regression a problem when using indirect tax to solve market failure?
Takes a higher % of income of the poor than it does of the rich, causes inequity which most view as unethical
212
Why is it a problem that using indirect tax to solve market failure causes black markets?
Quality of product is likely to be lower- externalities grow
Black markets need policing, enforcement cost
Government revenue is lost
213
What is the cause of over/ under taxing when using indirect tax to solve market failure and why is this a problem?
Information gap, externalities are difficult to measure
Undertaxing is ineffective
Overtaxing is unfair to the poor, may cause firms to leave the business, leads to the rising of black markets
214
How to we show subsidy correcting market failure in production?
An arrow from MPC to MSC
215
How do we show a subsidy correcting market failure in consumption?
Shift the supply curve downwards, the point where it meets MPC should be parallel with Q*
216
How does a subsidy help to solve market failure?
Lowers production costs
Lowers price
Increases quantity
Solves underproduction and consumption
Allocative efficiency and welfare are gained
217
Why is cost an issue when using subsidy to correct market faliure?
Opportunity cost
Fairness to tax payer
Debt/ interest on debt if the money has been borrowed
218
Why is inelastic demand an issue when using subsidy to correct market faliure?
If demand is inelastic e.g public transport the size of the externality will not change very much and Q* is not reached
219
Why are over and under subsidising an issue when using subsidy to correct market faliure?
Under- externality is not fixed and Q* is not reached
Over- cost argument grows even more
Caused by the information gap- externalities are hard to measure
220
What could the firms do with a subsidy that would be an issue and not correct market faliure, why is this an issue?
Use it to cover debt, CEO could keep it for themself, pay their staff higher salaries
Price does not change, demand does not change, ineffective use of money
221
What is regulation?
A law enacted by the government that must be followed by economic agents to encourage a change in behaviour
222
What type of approach is regulation?
Command and control approach
223
Types of commands in regulation
Limit- e.g age limits or time limits for when you can purchase alcohol
Compulsory- e.g compulsory graphic advertising on cigarette packaging
Innovative regulation e.g pay extra for a plastic bottle and get the money back when you bring it back
Cap- e.g pollution caps
Bans- e.g public smoking bans
224
Types of control in regulation
Enforcement
Punishment e.g fine
225
Why is cost a problem with government regulation
Cost of administration + cost of enforcement
Opportunity cost
Fairness to taxpayer
Interest on debt if the money is borrowed
226
How is equity a problem in government regulation?
Fairness to firms- some firms may struggle more than others to reduce carbon emissions particularly older firms
227
How are black markets + unintended consequences a problem in government regulation?
Black markets- policing costs, gov rev is lost, welfare loss to consumers as product is likely to be of lower quality
Producers may find a way to cheat the regulation
228
How is setting the wrong strictness of regulation a problem?
Too lax- problem is not solved
Too strict- too burdening to producers as it discourages demand, firms may move to another country or shut which causes unemployment
229
How do tradable pollution permits work?
Government sets cap at Q* ( this assumes governments can perfectly measure the negative externality of pollution)
The total amount allowed by the country is divided up between firms, and handed out, this is known as as a permit (one permit is 1000 tonnes)
Firms now have a choice: invest in green technology or buy up spare permits
230
Why is it better for firms to invest in green technology over buying spare permits?
Firms can profit by selling spare permits
Firms will not be affected when the price of permits increases
231
Why are tradable permits for pollution effective?
Internalise the externality
Allocative efficiency is reached
232
Describe the price quantity graph of tradable pollution permits?
Demand is normal
Supply is perfectly inelastic (amount of permits will never change)
233
Why may price of a permit increase?
Demand may increase
Government may tighten cap
234
Why is enforcement an issue with tradable pollution permits?
Low income countries may not be able to afford this
Where there is an enforcement cost we must always consider opportunity cost
235
What are the unintended consequences of tradable pollution permits if the externality cannot be perfectly measured?
If the cap is too strict:
Some firms may close, which causes unemployment
Some firms may move to other countries, which causes carbon leakage and doesn’t solve the problem
Firms may pass on costs to consumers through higher prices, allocative efficiency and consumer welfare are lost
If the cap is too lax:
The problem is not fixed
236
Why is lack of international corporation a problem with tradable pollution permits?
China and USA, the two biggest pollutants, have not joined the agreement, is it effective?
Many developing countries will not join as they want the opportunity for economic growth, this is bad because these countries are some of the biggest polluters
237
What is state provision?
Direct provision of goods and services by the government for free at the point of consumption
238
What are examples of state provision?
Healthcare and education
239
How does state provision work?
Government provides the socially optimum quantity of recourses( healthcare and education) this assumes that the government can perfectly measure externality
It is now free at point of consumption
Underproduction/ consumption is solved
Allocative efficiency is reached
240
Describe the price quantity graph for state provision
Supply is perfectly inelastic
Demand is normal
241
When is state provision needed?
When a good would be under consumed and underproduced in the free market
When there is inequity over a good
242
Why is excess demand an issue with state provision?
Medical- long waiting list of people who have to live in pain- who deserves to be treated first is normative
Education- may be larger class sizes- people pay in non monatory ways
243
Why is inefficiency of state organisations an issue with state provision?
No profit motive= organisations may be unproductive, this is very wasteful
244
Why is cost an issue with state provision?
Opportunity cost
Fairness to taxpayer
Debt if money is borrowed
245
Why is imperfect information an issue with state provision?
Externalities are difficult to measure, may be an over or under allocation of these goods
246
How will (theoretically) a price floor help to resolve market failure?
Contract demand - discourage consumption-quantity will fall
Externality is internalised
Welfare is maximised as socially optimum level is reached
247
Why would price inelastic demand be a problem when using a price floor to resolve market failure?
There will be no contraction of demand therefore Q* will not be reached
248
Why does a price floor lead to regression?
Higher prices burden the poor more than the rich, increases income inequality ( regression)
249
What are the problems with black markets being created when using a price floor to solve market failure?
Monitoring cost- opportunity cost
Consumer welfare is lost as this product is likely to be of a lower quality
Gov rev is decreased, due to legal businesses making less money to pay to the government
250
What are the problems with difficulty setting the price floor at the right level in solving market failure?
Externality’s are difficult to measure, governments are very unlikely to have perfect information, therefore it is unlikely the price floor will be set at Q*
If it is too high, it will burden producers too much, they may leave the country, or close down, which would cause unemployment
If it is too low then Q* is not reached
251
How does a price ceiling (theoretically) solve market failure?
Extension of demand of essentials, equity is increased, e.g rent controls
252
Why is excess demand a problem when using a price ceiling to resolve market failure?
Leads to a shortage and people going without essentials e.g accommodation
253
Why re black markets a problem when using a price ceiling to resolve market failure?
Monitoring costs- opportunity cost.
Consumer welfare is lost as this product is likely to be of a lower quality than a similar product sold in a legal market
Gov rev is lost as legal businesses are making less profit and are therefore paying less tax
254
Why is decreased quality of good/ service an issue when using price ceilings to resolve market failure?
Landlords/ producers have no profit motive, therefore will not try to improve their product
Landlords may “cheat” for example by charging for a key or to rent furniture, therefore the real price of rent would not change
255
Why is setting the right level of price ceiling a problem when trying to resolve market failure?
Externalities are difficult to measure, especially as governments usually have imperfect information
If the price ceiling is too low, there will be massive amounts of excess demand
Too high: equity not reached
256
What are the costs involved with using a price ceiling to resolve market failure?
Enforcement cost- opportunity cost
Government may have to subsidies landlords/ bus companies for a price ceiling- opportunity cost and fairness to taxpayer have to be considered
257
What is information provision?
Government funded information provision/ advertising/ education in order to encourage or discourage consumption of certain goods
258
What are some examples of information provision?
School curriculum, TV, newspapers, billboards, magazines, news, radio
259
After information provision for a merit good, what would happen to the demand curve?
It shifts upwards
260
After information provision for a demerit good, what happens to the demand curve?
It shifts downwards
261
What is the purpose of information provision?
Consumers now have more information about the goods they are consuming, so will now have a better understanding of the utility they will gain (mpb)
This will shift the demand curve in the desired direction
Allocative efficiency is now reached
This is a market friendly, less paternalistic technique
262
Why is cost an issue with information provision?
Administration cost- opportunity cost
If the money is international debt then this will have to be payed back with interest
263
Why is the fact that there is no success guarantee an issue when using information provision to correct market failure?
Lots of cost involved which could be money wasted- inefficient allocation of resources
Consumers may continue to act irrationally, as they may of understand the information or choose to ignore it- consumer weakness at computation
264
What kind of technique is information provision?
Long run not short run, this means that results may not show very quickly
265
What are property rights for market failure?
Giving a private producer the right to own part of a common access resource
266
How does giving property rights of common access resources help to solve market failure?
The producer will have no incentive to exploit the recourse as this will lead to resource depletion which will affect future profits
Negative externalitity internalised
Supply will now be at Q*
267
Why is difficultly with effective distribution an issue when using property rights for common access resources to solve market failure?
The air/ sea cannot be divided up
268
Why is cost an issue when using property rights for common access recourses to resolve market failure?
Enforcement cost (opportunity cost) if this cannot be afforded them there will be mass trespassing
269
Why is inequity an issue when using property rights for common access recourses to resolve market failure?
If two parties both desire ownership of the same common access recourse, only one can be granted this. The party with ownership rights can sell access to the other, however this will burden the consumers financially. Who deserves ownership rights more is normative
270
Describe the ownership of different economies?
Private- everything is privately owned
Command- everything is publicly owned
Mixed- There is a mixture of privately and publicly owned goods and services
271
Describe the motives of different economies?
Private-profit motive MPC
Command: welfare maximisation MSC
Mixed: Goods/ services which are privately owned will have a profit maximisation motive and those which are publicly owned wil have a welfare maximisation motive
272
Describe the freedom of choice in different economies?
High in a private economy
Low in a command economy
Medium in a mixed economy
273
Describe the competition in different economies?
Higher in private economies
Lower in command economies
Medium in mixed economies
274
Describe the extent of the role of the government in different economies?
Private- extremely low
Command - extremely high
Mixed- in the middle
275
Describe the variety and quality of different goods and services in different markets?
Market- high
Command- low
Mixed- in the middle
276
Describe the response to demand in different economies?
Private- quick
Command- slow
Mixed- medium
277
Describe the efficiency of different types of markets?
Market economies- allocative efficiency is reached as wants and needs of consumers are being met, however Q* is not reached as externalities will not be accounted for
Command economies- lower efficiency as there is no profit motive therefore no incentive to cut costs, this means there is a higher probability of wasteful production. However, these economies are less likely to suffer from market failure
Mixed economies- total efficiency is maximised
278
Describe the shortages/ surpluses created by different types of markets?
Market economies- non existent
Command economies- yes due to lack of price mechanism and imperfect information
Mixed economies- there will be some within the privately owned parts of these economies but none within the publicly owned parts
279
Describe how merit goods are allocated in different types of economies
Private economies- merit goods will be under provided
Command economies- merit goods will be provided at socially optimum rate
Mixed economies- there is likely to be government intervention
280
How are demerit goods allocated in different types of economies?
Will be over provided in a market economy
Will be provided at socially optimum rate in a command economy
In a mixed economy there is likely to be government intervention
281
Describe the allocation of public goods in different types of markets
In a market economy there is likely to be missing markets
In a command economy they will be provided at the socially optimum rate
In a mixed economy there is likely to be government intervention
282
Describe the income distribution in different types of markets
Most economists argue that the distribution of income in a private economy is too unequal and is unfair
In a command economy it is usually more even
In a mixed economy there is progressive tax (using income tax which is primarily taken from the rich and using it to help the poor) and welfare state (ways of people having an income without working for example benefits or state pensions)
283
Describe the extent of negative externalities in different economies
Market economies- overproduction of goods and services which generate negative externalities
In command economies all externalities will be accounted for so production and consumption will be at the socially optimum level
In mixed economies there is likely to be government intervention
284
Describe the likelihood of monopoly’s in different markets
Likely to exist in market economies
Impossible to exist in command economies
In a mixed economy there is likely to be some government intervention
285
What are different types of markets like in the real world?
Pure market economies don’t exist in the real world, however some economies which are mainly market based include the USA and Singapore
Pure command economies also don’t exist, however some economies which are mostly command are North Korea and Cuba
The majority of economies are mixed economies
286
Why is it good that the free market creates allocative efficiency?
There will never be a long run disequilibrium
287
Why is it good that free markets encourage competition?
More choices, higher quality of goods and services, firms will strive to produce efficiently in order to enter competitive prices, consumer welfare is high
288
What is the risk of government failure in a free market?
Non existent
289
Why is it positive that consumer have more choice in a free market?
More individual liberty and freedom, higher consumer welfare is
290
What is dynamic efficiency and why is it positive that this exists in the free market?
Profits made going back into the firm in order to improve it, for example more in work training or improving capital
This will increase the quality and quantity of goods and services produced
As quantity is at its maximum, jobs in this industry will also be maximised, meaning people have the ability to earn higher incomes
This will mean they have more purchasing power, which will lead to economic growth
291
What are the failures and why is risk of market failure a negative of free markets?
Monopoly power may mean high barriers to entry for other firms
There may be imperfect information which could lead to irrational decisions from consumers as they do not understand the true utility the good or service is providing them
There would be missing markets of public goods
Externalities are ignored, meaning it is unlikely that production and consumption will be at socially optimum level
292
Why is inequity an issue in free markets?
Some consumers may be excluded from consuming necessary goods and services
293
Why is excessive profiteering an issue in the free market?
Firms may cut wages, costs for health and safety or costs for things which are beneficial to society
294
Why is creative destruction an issue in the free market?
If there was monopoly power for one good, and another good was introduced which consumers believed would provide them more utility, consumers are likely to switch meaning the original firm may close
295
Why is price volatility in the free market an issue?
If prices are too high, there is an extreme burden on consumers
If prices are too low, there is an extreme burden on producers
296
What is specialisation (countries)
The concentration of production on a narrow range of goods and services
297
What is the advantage of maximisation of output after specialisation?
Countries will only produce what they are most efficient at, which will mean they will make more revenue when trading with other countries. This will lead to global economic growth
298
What are some other advantages of specialisation?
Wider variety of goods and services
The problem of scarcity is overcome which leads to greater allocative efficiency
Costs of production are lower as workers are more specialised
299
What are the disadvantages of specialisation?
A change in fashion or trends could lead to firms shutting down
National interdependence is required- if there are international relations issues the entire system will fail
Finite resources- if a business only produces petrol and oil runs out, then this firm will shut down.
De-industrialisation - if a foreign firm becomes more efficient at production, then the original, less efficient firm will shut down
300
What is division of labour?
Breaking down the production process into separate tasks upon specialisation
301
What are the advantages of division of labour?
Workers are highly productive- this saves time which lowers the cost of production. This means that the profit ability for the firm is high, which can be passed onto consumers through lower prices.
Specialist capital for workers can be created.
There are lower prices, higher quality and quantity of goods and more choices, which means that consumer welfare is maximised
302
What are the disadvantages of specialisation of labour?
Demotivating of workers- over time productivity may decrease, which may lead to high staff turnover- this may increase training costs and be inefficient in the long run
Risk of structural unemployment long term for workers if they are only qualified to do one thing and it gets replaced by capital
Goods become highly standardised, uniqueness which many consumers love is lost
303
What is a primary commodity?
Output from the primary sector, whose activities supply unprocessed raw materials
304
Why is PED inelastic for primary commodities?
They are necessities an there is often a lack of good substitutes
305
Why is PES inelastic for primary commodities?
Large production lag
Hard to store- low stock
306
Why are there regular changes in the demand curve of primary commodities?
If there is global economic growth there will be an increase in demand. If there is a slow down in economic growth there will be a reduction in demand for primary commodities
307
Why are there regular shifts in the supply curve for primary commodities?
Changes in weather affects production of agricultural goods
308
What happens if demand of primary commodities increases?
Producer revenue will increase, could lead to greater dynamic efficiency, the business has higher profitability potential and producer living standards increases
309
What happens if prices of primary commodities fall
Revenue falls drastically, living standards and profit ability also fall, in developing countries this leads to absolute poverty
If many producers leave the market, there could be supply concerns
Government revenue and export revenue both decrease, this could worsen poverty particularly in developing countries
Investment will decrease as producers won’t spend on capital
310
How does an economist create a theory (demand theory)
Observe consumer behaviour
Form hypothesis on how consumers spend
Make predictions from their hypothesis
Use evidence to test predictions
311
What happens if evidence does not support a prediction?
It is rejected
312
What happens if evidence does support the hypothesis?
It becomes a theory, and there are more tests to strengthen the theory
313
What is a vebling good?
Designer brand which the consumption will increase for given higher prices
314
What is gilling good theory?
When prices increase consumers will buy more as they will switch their income from other gods and services
315
What is economics?
A positive subject and a social science
316
What is the difference between the gradient and the elasticity along the demand curve?
Gradient stays the same but elasticity varies
317
Why are gradient and elasticity different?
Gradient is a basic number whereas elasticity is based on percentage change
318
Describe elasticity along the demand curve
The top half is always elastic whereas the bottom half is inelastic
Order: perfectly elastic, elastic, unitary elastic, inelastic, perfectly inelastic
319
What elasticity should firms have in order to maximise revenue?
Unitary price elasticity
320
Describe the revenue quantity graph
An N shaped curve
321
Water scarcity in India- case study example
Caused by ground and surface water drying up, also due to population growth (increase in demand) drought (decrease in supply) and poor monitoring of water resources. This has led to a significant price increase, which burdens families and farmers. There is huge concern for the future as both ground and surface water are running out. Farmers are having to dig deeper and deeper to access water which is extremely expensive
322
Markets in action- demand shift to the left
Peloton bikes- reports of dangerous design faults and a return to office work
Non-essential tech goods such as smart speakers- inflation has reduced the purchasing power of consumers, reduce the willingness and ability to buy
Printed newspapers- online news papers are cheaper and in trend, most people are switching to these
Student housing- rising cost of university has led to many students to live at home with their parents while studying
