money and banking
Trade: the exchange of goods and services between different parties. People/countries trade because it is impossible to reach self-sufficiency.
Hence there is a need to trade to get the goods and services you use to satisfy your needs/wants.
Specialization: each worker of a firm specializes in different goods/services.
International specialization: each country specializes in different goods/services.
Advantages:
Faster production
Better quality
Cheaper production
Result: people/countries have to trade to get goods/services they don't produce.
Exchange rates depend on scarcity.
The problem of the double coincidence of wants:
Most of the time it isn't: they want what I have, I want what they have.
5 characteristics of money:
Money must be divisible (no eggs)
You can pay smaller amounts
Money must be portable (not cars)
For convenience reasons
Money must be durable (not grapes)
Have to be used repeatedly
Money must be recognisable (this is done through the water mark) (not a rock)
Accepted everywhere
Money must be scarce (otherwise it will have no value) (not sand)
To keep value
5 functions of money:
Medium of exchange
Unit of account
Store of value
Standard for deferred payment
Medium of exchange:
Used to swap goods/services in exchange for money
Before there was money there was barter trade, swap goods/services in exchange for other goods/services
Unit of account
Money is used to account for the value goods/services
Makes it possible to compare values of goods/services
Ex: prices for different car types
Store of value
Money is used to save/store your wealth
wealth=your possessions
Wealth can be stored in valuables like gold, jewelry, property and money
Banks offer services to store your wealth safely with them (and can even reward you with paying interest)
Standard for deferred payment
Allows you to borrow money. Money can be used to pay off debts
Ex: you want a new car, how to pay for this?
You can borrow money/take a loan and use it to buy a new car.
Deferred payment: payment postponed
Commercial and central banks
Want to make profit
Provides commercial services to individuals, firms and governments
Makes profit from insurance and interest
They:
Keep money safe
Pay interest for saving deposits
Charge interest interest on loans
Enable payments between people, firms and governments
Charge fees for the provision of other financial services: private banking/wealth management (only for high-income households)
Insurance
Credit card
Foreign currency/money changer
Make investments in new firms
Interest rate
For customers -> reward for putting their money in the bank
For borrowers -> cost of borrowing money
Banks also make money from insurance and currency exchange. The difference in interest rate is profit for the bank.
Type of lending by commercial banks
Overdraft: taking out more from your bank account than you have. Short-term, ex. To pay bills
Loans: borrowing a fixed amount of money to buy expensive things, ex. A car or new household appliances
Mortgage: borrowing a fixed of money to buy a house, if it cannot be repaid, the bank will take the house
Central bank: bank organisation entrusted by the government to supervise all commercial banks and carry out monetary policies.
Roles of central banks:
Issue money - notes and coins
Supervise banking sector in the country
Supervising monetary policy of the government
Governments and commercial banks banker
Lender of last resort
Coordinating with other central banks and international financial institutes (like in the 2008 market collapse)
If there is too much money in circulation it would lose its value, so only the central bank is allowed to issue money.
Commercial banks may only operate in a country after approval from its central bank.
Central banks can revoke the licence of commercial banks if they break the law.
Central banks also determine how much money can be lent out to the public.
Central banks hold the government's main account.
It keeps the country’s gold and foreign currency reserves.
All commercial banks hold bank accounts with the central bank, they can lend money to commercial banks.
If commercial banks run out of money they will borrow first from other commercial banks. If that doesn't work central banks will step in and lend money to them.
In the financial crisis of 2008 central banks had to ‘pump’ money in commercial banks to prevent bankruptcy.
Questions: why is a good banking system important for trade?
What is the function of the gold and foreign currency reserve?
Explain how the central bank can influence the rate of the economy?
Who benefits from a higher interest rate?
Who benefits from a lower interest rate?
If there is high unemployment would it be better to raise or lower the interest rate? Why?
If prices rise too fast should the interest rates rise or fall? Why?
Question 6. Central banks lower interest rates → commercial banks lower interest rates → more borrowing because it's cheaper → more spending → forms produce more output → firms hire more labour
Question 7. central banks raise interest rates → commercial banks raise interest rates → less borrowing because it's expensive → less spending → lower prices
Households/income
Gross income: income before tax.
Disposable income: income available for consumption after all tax is deducted.
Nominal income: income absolute numbers.
Real income: income adjusted for inflation.
Factors that influence choice of occupation
wages/salary (wages are paid by the hour, salary by the year)
Basic pay
Overtime
Bonus
Commission (salesmen)
Non-wage factors
Job satisfaction (voluntary)
Make new contacts
Learn new skills
Career prospects
Possibility of getting a promotion to a desired higher position
Fringe benefits
Questions: compare the salaries of a pilot and cashier, explain the differences.
Find 2 other occupations and compare them as well, explain the differences.
What are the benefits and the disadvantages of a piece rate wage?
Why may some people choose a low paying job?
Define specialization of labour.
Explain one benefit and one disadvantage of the above.
Demand for labour
Derived demand: demand for labour depends on the demand for the output they produce. Ex: demand for the steelworkers increases if there is more demand for cars.
Supply of labour
Higher wage rates lead to workers willing to work more hours (normal supply curve)
However at a certain point wages have reached a point that workers are satisfied and choose to relax, even though, the wage rises (backwards bending supply curve)
Market wage: the equilibrium price of labour
Where supply of labour = demand for labour#
Demand and supply for labour
Factors affecting the wage rate:
Relative bargaining power
If the trade union is more powerful they can ask for higher wages
Age/experience: older workers are more experienced and hence can ask for higher wages.
Level of education: higher education can give more power to starting workers to ask higher wages.
Minimum wage
Governments can set a minimum wage to support low-income households and to prevent exploitation by large firms who want to keep production costs low.
Benefits: workers now receive a fair income in order to survive and afford basic necessities. Workers are not looking for a job because the wage is too low and are now encouraged to look for a job. Low income households now have more money to spend which is good for economic growth.
Disadvantages: higher production costs for firms. Firms may have to increase prices, which could cause inflation. Oversupply of workers: firms may be reluctant to hire more workers at higher wages and may even fire workers to lower production costs hence creating more unemployment.
Wage differentials
Skilled vs. unskilled workers: skilled workers have higher productivity and their output has more value. Supply of skilled workers is also lower.
Public vs. private sector: basic pay in the public sector is higher but total earnings in the private sector are often higher because of bonuses and overtime.
gender/race wage differentials:
Women work a shorter period of their life compared to men
Women work more often part-time jobs
discrimination/racism
Agriculture vs. manufacturing vs. service jobs
Derived demand influences heavily the wage rate for workers
Demand for skilled manufacturing jobs or service jobs is higher than agricultural jobs, hence the wages in these industries is higher.
Age: older workers are paid more that younger workers due to:
More experience and better skills
Hierarchy: older workers are often higher ranked than younger workers
Need for higher earning due to hiring costs
Reasons to choose low-paying jobs
Job satisfaction
Comfortable working conditions
Nice colleagues/manager
Short home-work travel distance
Easy working hours
Simplicity of the job
No choice/necessity
trade/labour union
A trade union is an association of employees with the objective to protect the rights of workers.
Members pay fees and can turn to unions in case of problems or questions regarding work.
Advantages:
Trade union can:
Negotiate better wages and/or working conditions for its members
Give legal advice to its members in case of problems (dismissal, working conditions)
Organise protest against firms in case of a problem
Provide (free/cheaper) training to upgrade skills of members
Power in numbers
Increase in salary
If it doesn't work they go on collective action/strike
If employees stop working firms lose money and profit
Might not work if:
They can be replaced by machines
No freedom of speech
Not enough strikers
Questions: can the labour union negotiate higher wages if:
There is huge unemployment? Why?
There is a shortage of workers? Why?
They have few members? Why?
Workers can be replaced by robots? Why?
Spending, saving, and borrowing
Reasons to buy things
Satisfy needs
Satisfy wants
Conspicuous consumption:
People buying goods, services that give them the feeling of a higher social status (veblen goods).
In order to consume, people need money from income or they can borrow or use their savings.
Factors that affect consumption
Income
Disposable income: income after taxes paid
Gross salary: before tax
Net salary: after tax
Wealth
Income+wealth=all valuable possessions
Income, savings, real estate, stock instruments, jewellery/gold, collector items
Consumer confidence about future
Interest rates
Low income families spend most of their money on basic needs: food, water, housing
High income families spend relatively less on basic needs but more on luxurious goods like electronic gadgets and leisure goods.
Reasons for saving:
Saving for suture consumption
Gain interest over their savings
Precaution (for future emergencies)
Reasons for borrowing:
Survival/unable to buy goods/services
Price of desired goods service is too high to pay at once (car)
Factors affecting borrowing
Interest rate
Wealth
Consider confidence about the future
availability to borrow
If the borrower is unable to repay the loan: bankrupt or insolvent.
Individuals go bankrupt.
Companies go insolvent.
Financial crisis: too many us borrowers unable to repay loans
Loan to buy a house: mortgage
If you are unable to repay a mortgage, the bank will take the house
Interest rates
Cost of borrowing money; borrowing money is actually buying money from a financial lender like banks
Reward for saving money; where households put their money in the bank and they lend the commercial banks their money.
Interest rates determine the level of trade in the economy. When commercial banks borrow from the central bank they pay the discount rate.
The more borrowing the more consumption and investment.
Consumption: households spend
Investment: firms spend (capital+labour)
Questions: what will happen to spending, saving and borrowing? Why?
Income rises
Consumers are pessimistic about about the future
Banks raise interest rates
Governments limit the use of credit card
Types of business organisation
Public sector
Involves firms owned/controlled by the government/city councils.
Ex: public transport, public schools, public hospitals, public libraries
Firms that are financed/subsidised by the government and serve the public interest instead of making profit. Usually offer for free or low price.
Private sector
Involves firms that are privately owned by individuals, a group of individuals, or shareholders.
Their main objective is often to make profit or manage private money (charities/donations)
This can be small firms like sole trader (1 owner); partnership (2 owners); to private/public limited companies
Multinationals
Firms that produce and sell in different countries
headquarters/head office in 1 country but side offices/factories worldwide. Ex: mcdonalds
Public corporations/public sector organizations
Organisation owned by the government
Objective: provide goods/services necessary for society.
Ex: utility companies (gas, water, electricity, public transport)
Disadvantages:
Require tax money to be financed
May become very large and difficult to manage - inefficient
Privatization: public corporations become private firms.
Have to compete to make more profit hence it becomes more efficient.
Growth of firms
Firms may grow in size. This may require changing the type of organisation. Ex: mcdonalds grew from partnership to public limited company.
Changing type of organisation is due to:
Acquiring more financial funds through stocks/shares
Protecting owners from huge debt
If the company goes insolvent consumers lose the value of their shares
Advantages of growing as a firm
Able to raise more money
Attract talented and better skilled employees
More famous as a brand
Conduct more research to develop new products/improve quality
Able to expand to other countries
Demand for factors of production (FOP)
Derived demand: need one good to produce another.
Demand for labour is derived from the demand for the output they produce.
Demand for the FOP is also derived. Ex: more demand for coffee means more demand for
Land to produce coffee beans
Coffee shop staff/baristas
Coffee makers
Owner of the cafe
If people pay the franchise for the anime that is already popular it is called a franchise fee.
Labour-intensive vs. capital-intensive production
Labour intensive production
High proportion of labour used in the production process compared to capital. Ex: restaurants and textile industry.
Capital intensive production
High proportion of capital used in the production process compared to labour. Ex: car and food-processing industry
Production vs. productivity
Production: process of making goods/services (output).
Productivity: output produced per worker per time period.
The value of output being higher does not mean they are working much harder.
Higher productivity could be achieved through
Education and training
Better technology (like the computer)
Use of capital (robot)
Use of fertilizers (agriculture)
Sectors in the economy
Primary sector (extraction of raw materials)
Renewable or non-renewable energy (fishing, oil agriculture, mining, forestry)
More dominant in less developed countries
Manufacturing sector (secondary sector)
Manufacturing (factories and construction companies)
Utilities
Combines raw materials into goods
tertiary sector (production stages)
Retail, communications, healthcare, IT, entertainment, shops, hotels, sales, transport services
Services to customers
+insurance and banking
Increased a lot in the last century
revenue-production costs=profit
Costs: the payment that the firm has to make to produce goods and services.
Raw materials depend.
Rent is fixed.
Cost types
Total cost (TC): the total sum of all costs
Total fixed costs (TFC): costs that do not change when output changes in the short run. They exist even at zero output. Ex: rent or interest on a bank loan. The firm still has to pay rent or interest even though it is not producing.
Total variable cost (TVC): costs that change when output changes. Ex: electricity; the more production, the more electricity needed. The TVC curve is upward sloping starting at the origin.
TC=TFC+TVC
Total revenue=price x quantity
TR=P x Q
Total cost=total fixed costs+total variable costs
TC=TFC+TVC
Total profit=total revenue-total costs
TR-TC
Average fixed costs=total fixed costs/output
Average variable costs=total variable costs/output
Average total cost=total cost/output
When TR=TC it's called Break Even.
ATC>TR otherwise there is no profit
Fixed costs: independent from output
Interest over bank loan
Rent
Administrative staff
Investment for office computer
Advertisement cost
Variable cost: dependent on output
Electricity
Overtime payment
Raw materials
Fuel for company car
Business goals
Maximize profits
Maximize sales/increase market share (want to become more famous)
Expand into other countries
Creating a good reputation (ex: Gucci)
Survive against competition
Market structures
Where buyers and sellers interact
Not necessarily a place, could be online, in a city/country or even the whole world. Ex: pizza restaurants and sushi restaurants, the market for pizza is bigger
Characteristics of market structure
Number of big sellers
Type of good/service
Entry to market (easy or difficult to start a business?)
Number of sellers, many? Few?
If there are many sellers, can each seller charge a high price?
Price taker: firms that follow the price of other competitors. The firm is too small to charge a higher price than other competitors.
Price setter: firms that are able to set higher prices than other competitors because they all sell something unique. Ex: apple and IOS.
Type of good
Homogenous: the good/service is identical for the buyer (kind of metaphorical). Ex: electricity
Differentiated: identical but slightly different. Ex: pizza from Dominos or New York Pizza
Unique: only one type available. No close substitutes available.
Access to market: is it easy or difficult to start a business?
Barriers to entry: obstacles that prevent a business from starting. Ex: start-up costs; technology, patents/copyrights, regulations (licence/permission required from the government)
perfect competition
Market structure/situation with many sellers who sell the same good/service.
Many sellers price takers. Most sellers change roughly the same prices.
Monopoly
Market structure/situation where only one firm sells a unique good or differentiated good with almost no substitutes.
The firm has a lot of power to change their own price without fear of losing customers: price setter.
So the government sets a price ceiling.
Pure monopoly rarely exists. Most monopolies are government owned. Ex: public transport/utility companies.
Monopolies can be created through
Government. Ex: public transportation
Regulation
patents/copyrights
Contracts between firms (coca cola and mcdonalds)
Brand loyalty through advertising
Size of firms:
Number of employees
Generally less than 50 means small, unless there is a lot of capital involved in the production process.
Organization (number of departments/branches)
Capital employed
Market share
Firms revenue/total market revenue
Total market revenue=revenue made by all firms in the industry
Diversification
Some firms have grown large because they produce a diverse range of goods/services. This is called diversification: producing different types of goods and services by one firm. Ex: apples: smartphones, earphones, tvs, music devices
How firms grow in size
Internal (organic growth)
Firms grow by increasing output produced. Ex: mcdonalds started with two restaurants opening and then worldwide
External growth: firms joining together to form a larger firm: integration
Merger. Ex: disney and marvel
Takeover and acquisition
horizontal integration
merger/takeover of firms of the same type of good/service. Ex: Adidas and reebok. Meta acquiring Instagram and facebook. Also competition is reduced.
vertical integration
Merger takeover of firms at different stages of production. Ex: Toyota taking over a tyre factory. This ensures enough supply of tires and means they can esure production costs themselves.
Forward integration
Firms taking over other other firms in the next stage of production/its consumer. Ex: factory takes over shop (milk factory takes over cheese factory)
Backward integration
Firm taking over other firms in the previous stage of production/its supplier. Ex: factory takes over supplier of raw materials ex: milk factory takes over dairy firms
Ex: Shell, oil fields->oil refinery->gas/fuel stations
Reasons for integration with other firms
Increase market share (take over customers)
Eliminating competition (competitor does not exist anymore because it's taken over)
Taking over assets and technology from other companies. Ex: marvel copyrights on superheroes taken over by Disney. Nokia technologies taken over by microsoft (2014)
Ensuring stable supply of raw materials (backward vertical integration 0 ensuring places to sell their own products. Ex: Apple and Apple stores
Economies of scale. Reducing average total costs by becoming bigger.
Economies of scale: a decrease in average costs due to an increase in output produced.
The larger the firm, the lower the costs.
Internal economies of scale: decreasing unit costs due to firms growing internally.
External economics: decreasing unit costs due to the whole industry/market growing.
Internal EOS
Purchasing economies: lower costs because firms buy in bulk quantities and receive discounts
Marketing economies: ad costs are lower because it spreads over a large output. Ex: coca cola produces thousands of bottles each day, so their market cost is low.
Financial economies: large firms can borrow more at lower interest rates because the bank trusts them more.
Technical economies: large firms have more money to buy better equipment and hire researchers. This better equipment lowers costs. The researcher can develop new technology which lowers costs as well.
Risk-bearing economies: large firms produce a large amount of different goods/services. The loss of one good can be compensated by profits on other goods.
