Lecture 1 Flashcards
What is Demand?
When the price of a good rises, the quantity demanded will fall.
What 2 factors affect demand?
- Income Effect - prices increasing results in less disposable income so people can’t afford as much, hence demand decreases.
- Substitution Effect - good is now more expensive than other good so people swop for alternatives.
What assumption is the demand curve constructed under?
The demand curve is constructed under the assumption that other determinants of demand remain equal, only price is changing.
How does a change in price affect the demand curve?
Change in price = demand curve shifts up or down.
How is the demand curve affected by non-price determinants?
The demand curve shifts left or right.
List the determinants of demand?
Price
Taste
Previous Experiences
Observing what others do
Health
Fashion
Substitute goods - number of competitors and their prices
Complementary goods - good consumed together (bread+butter - if the demand for one decreases, the demand for the other may also decrease).
Income - income increases then demand for good increases (normal goods). If income increases and demand for good doesn’t increase then it is an inferior good.
Expectations for future price changes - if prices are expected to fall then consumers may wait before purchasing.
Future income increase and decrease.
Describe the supply relationship.
The higher the price of a product, the more the producer wants to supply to the market.
The higher the price of the product, the more profitable it is to make.
Cost of supplying the good increases with greater quantities of supply. Only worth producing more output when the price of a good increases.
How does the supply curve change with price?
A change in price causes the supply curve to shift up or down.
How does the supply curve change with non-price determinants?
The supply curve shifts left or right.
What are the determinants of supply?
Cost of production - As cost increases, profit decreases. As costs increase, firms cut back production perhaps switching to a good whose costs haven’t risen as much.
Profitability of substitutes
Profitability of goods in joint supply.
Random shocks: nature/unpredictable events/weather
Aims of producer/manager - some may want to profit maximise others have different aims.
Expectations of future price changes - if prices are expected to rise, firms may temporarily reduce the amount they supply.
What are the two meanings of substantivism?
Formal - Economics is the logic of rational action and decision making.
Economies and economic choices are embedded in society and culture.
What is the problem of scarcity?
At any one time, the world can only produce a limited amount of goods and services. This is because the world has only a limited amount of resources.
Define Scarcity
Scarcity is the excess of human wants over what can actually be produced.
Define production
The transformation of inputs into outputs by firms to earn profits (or to meet some other objective).
Define consumption
The act of using goods and services to satisfy wants. This will normally involve purchasing the goods and services.
