Theme 1: Introduction to markets and market failure Flashcards
What is the basic economic problem and opportunity cost? (1.1) (2)
-The basic economic problem is that we have unlimited wants, but limited resources, forcing us to make a choice, leading to scarcity and opportunity cost
-Opportunity cost is the next best alternative foregone when making a choice
Why do economists use models, and what is ceteris paribus? (1.1) (4)
-Economists use models to make predictions about the future direction of the economy
-a partial model looks as aspects of the economy, whereas a macro model looks at the whole economy
-When making the models, assumptions have to be made when analysing a specific cause/consequence
-Ceteris Paribus is the assumption that ‘all other things remain unchanged’
What is specialisation? (1.1) (2)
-Specialisation is when individuals, firms regions and countries focus on producing what they are best at doing so, to maximise output and profit
-The division of labour is the separation of the work process into a number of smaller tasks, each task performed by a separate person/group of people
What is a command economy, and what are the pros and cons of one? (1.1) (8)
-A command economy is one where the government dictates the production of goods and prices, and controls their distribution, wages and prices
-The four key components of a command economy are: government control of key business, government control of property rights, government control of wages/prices and a strong black market
+The government can change what is produced based on the needs of the people
+There is very low unemployment in a command economy
+There is very low inequality in a command economy
-A command economy discourages efficiency and innovation by firms
-Workers do not get to choose what work they do
-A strong black market leads to crime
What is the difference between a positive and normative statement (1.1) (2)
-A positive statement is one which can be proven/disproven, made based on fact and not valued judgement (objective)
-A normative statement is one which cannot be proven/disproven, made based on valued judgement and not fact (subjective)
What is productivity? (1.1) (2)
-Productivity is the measure of the efficiency with which a country combines factors of production to produce more with the same level of factor inputs
-Calculated with output per unit of input
What is a free market, and what are the pros and cons of one (1.1) (8)
-A free market is an economic system based on the interaction of supply and demand, with little/no government intervention
-A free market is characterised by: freedom of enterprise, property rights, a competitive market and profit as an incentive
-A free market encourages efficiency and innovation
-Consumers control what is produced through their choices
-Invisible hand provides natural regulation
-Poor working conditions, as firms prioritise profit
-Vulnerable to heavy recessions with little solution
-People not useful for production purposes (elderly, disabled …) get left behind
What causes a shift in the PPF (1.1) (7)
-A shift in the PPF is caused by a change in the quality/quantity of factors of production
-Changes in the working age population
-Changes in education/training
-Changes in international trade of capital
-Changes in innovation
-Natural disasters like floods and droughts
-Discovery of raw materials
What are the positives and negatives of specialisation for workers and firms (1.1) (8)
-Workers can do something they enjoy, and are good at
-Workers can increase their productivity, leading to increased output and increased wages
-Workers may get bored of doing the same thing every time
-If their work is no longer needed and they lose their job, workers will find it harder to retrain
-Firms can increase their productivity, therefore increasing output and therefore profit
-By increasing productivity, firms need less FOP’s than before, decreasing costs of production
-If one part of the production process fails, the entire system collapses
-If demand for the produced good falls, firms revenue will drop with no easy way to switch production
What are the pros and cons of specialisation of regions and countries (1.1) (8)
-Specialisation leads to higher output, leading to more demand for workers and decreased unemployment
-Higher incomes in the area leads to higher spending and council tax in the area, all of which will improve it
-Increased production may also come with over-abstraction of resources
-If demand for the specialised good falls, the region may collapse
-Higher specialisation allows countries to increase tax revenue, and pay back some of their government debt
-Higher specialisation leads to higher output and higher GDP
-Revenue from that good is dependant on international trade, and therefore any foreign restraints/recessions may hit the country hard
-Over abstraction of raw materials
What is a PPF (1.1) (2)
-A production possibility frontier represents the maximum combination of 2 goods/services that an economy can produce at a given point in time with all resources fully and efficiently employed
-The boundary represents scarcity, and movements represent opportunity cost
What is a mixed economy, and what are the pros and cons of said system (1.1) (8)
-A mixed economy is an economy with a mix of capitalism and socialism, allowing for both private and state enterprise
-The role of the government is to provide regulatory framework, ensure the welfare of the population and redistribute incomes
-Market economies encourage innovation and efficiently
-Governments have the power to decrease monopolisation
-Tax and Government spending can help redistribute incomes
-There will still be an emphasis on profit, and all the issues that arise with that
-With government intervention it is likely not maximum efficiency
-There is likely to be high income inequality in a mixed economy
What is demand (1.2) (5)
-Demand is how willing and able consumers are to buy goods and services at a given price at a given point in time
-Derived demand is demand for one good which comes from the demand for another (bricks and houses)
-Demand is downwards sloping since:
-As prices fall, consumers willingness and ability to buy rise
-Diminishing marginal utility (As consumption rises, additional utility falls and therefore the price willing to pay falls)
What is price elasticity of demand (1.2) (2)
-Price elasticity of demand is the responsiveness of quantity demanded to a change in price
-PED is calculated with %change QD / %change P
What factors cause a shift/movement on the demand curve (1.2) (8)
-A movement on the demand curve is caused by a change in price
-shifts are caused by PASIFIC
-Population
-Advertising
-Substitutes
-Income
-Fashion and trends
-Interest rates
-Complimentary goods
What are some factors affecting price elasticity of demand (1.2) (5)
-In the long run, PED is more likely to be elastic as consumers can look for other alternatives
-The larger the % of income a good is, the more elastic it will be
-If the good is a necessity, demand will be inelastic
-If the good is addictive, demand will be inelastic
-If there are many ready alternatives of high quality, the good will be elastic
What are some PED values (1.2) (5)
PED is always negative
0 = Perfectly inelastic
0>x>-1 = inelastic
-1 = unitary elastic
-1>x>-∞ = elastic
-∞ = perfectly elastic
What are different types of income elasticity goods, and how do firms use this info (1.2) (3,2)
-Goods with a negative YED are inferior goods, typically low cost low quality, where demand falls as income rises
-Goods with a YED 0<x<1 are normal goods, where demand rises as income does
-Goods with a YED>1 are luxuries, goods which demand largely rises as incomes rise
-In a recession, firms are more likely to produce inferior goods
-When the economy is doing well, firms will produce more luxuries
What is the difference between price elastic and inelastic (1.2) (3,3)
-Price elastic demand is when quantity demanded is very responsive to a change in price
-%change QD > %change P
-Firms with elastic demand should decrease the price to maximise revenue
-Price inelastic demand is when quantity demanded is not very responsive to a change in price
-%change QD< %change P
-Firms with inelastic demand should increase the price to maximise revenue
What is cross elasticity of demand (1.2) (2)
-Cross elasticity of demand is the responsiveness of quantity demanded of one good to a change in price of another
-%change QD of good A / %change P of good B
What is the difference between a shift and a movement on a demand curve (1.2) (2)
-A shift on the demand curve is caused by non price factors
-A movement on the demand curve is caused by price factors
What are some types of XED goods (1.2) (3,3,2)
-Goods with a positive XED are substitute goods
-For example, Pepsi and Coke
-if XED>1, then they are strong substitutes, otherwise they are weak ones
-Goods with a negative XED are complimentary goods
-For example, fish and chips
-if XED<-1, they are strong compliments, otherwise they are weak ones
-Goods with an XED of 0 are unrelated
-For example, cars and milk
What is income elasticity of demand (1.2) (2)
-Income elasticity of demand is the repsonsiveness of quantity demanded to a change in income
-%change QD / %change income
What factors cause movements/shifts of the supply curve (1.2) (1,7)
-A movement on the supply curve is caused by a change in price of a goods
-A shift on the supply curve is caused by non-price factors, being
-Productivity
-Indirect tax
-Number of firms
-Technology
-Subsidies
-Weather
-Cost of production
What is supply, and why is it upwards sloping (1.2) (1,2)
-Supply is how willing and able firms are to produce goods and services at a given price level in a given time period
Supply is upwards sloping since:
-As prices rise, firms can offset more costs of production, being able to produce more
-Higher prices acts as an incentive for higher production, as firms could gain higher profits
How do subsidies, weather and cost of production impact supply (2.1) (3,2,3)
-Subsidies are whena government pays part of the cost to the firm
-This leads to decreased costs of production to firms, and increased supply
-However, it depends on the extent of the subsidy, and how long it is given
-Weather impacts costs of production as poor weather leads to increased resource prices, and increased costs of production, leading to decreased supply
-This is heavily dependant on which sector you work in, agriculture being the one most impacted by weather
-Cost of production impacts supply since a decrease in the cost of production allows firms to supply more with the same resources, increasing supply
-However is this decrease in the cost of production short term or long term
-Firms may not want to increase supply, and decide to hoard the profits, as lower prices could be a sign of a recession
