How is demand and market demand curve sloped?
Negatively
How does changes in the quantity of demand affect the curve?
Its a movement along a given demand curve as a result of change of price in a commodity
How does changes in demand affect the curve?
A shift of the entire demand curve; which is caused by changes in variables other than price (mkt size, income, substitutes)
What is derived demand?
Is the demand for a good or service that results because it is an input needed in order to provide another good or service for which there is a demand
How is supply and market supply curved sloped?
Positively
As prices increases what happens to the aggregate supply of a commodity?
It increases
What is the market equilibrium price?
Qty of commodity supplied in the market is equal to the qty of the commodity demaded
What is a market shortage?
the actual price is less than the equilibrium price; therefore, the actual quantity supplied is less than the quantity demanded
What is a market surplus?
The actual price is higher than the equilibrium price; therefore, the actual quantity supplied is greater than the quantity demanded
What does elasticity measures?
Measures the % change in market factor as a result of a given % change in another market factor
What is elasticity of demand?
measures the % change in qty of a commodity demanded as a result of a given % in price of a commodity
How to calculate the elasticity of demand?
% change in quantity demanded / % change in price
What are the factors that affect elasticity of demand?
- Availability of substitutes - more substitutes more elasticity
- Extent of necessity - the more necessary a good or service, the more inelastic demand
- Share of disposable income - the larger the share of income the more elastic
- Postchange time horizon - the longer the time following a price change the more elastic demand of good
Why is price of elasticity important for a firm?
Because it indicates the extent to which a firm is likely to be able to pass in its cost of inputs to the customer:
- If the demand for a good or service is inelastic, them the firm can increase its selling price with less negative financial impact
- If the demand for a good or service is highly elastic, it cannot increase its selling price without significant negative financial impact
What is cross elasticity of demand?
Measures the % change in the quantity demanded as a result of a given % in the price of another commodity
- When the cross elasticity coefficient is greater than 0 the goods are substitutes
- When the coefficient is less than 0 the goods are complimentary
What is the marginal utility calculation?
MU/price of unit
A monopoly exist as a result of what?
- Control of raw material inputs or processes (e.g. patent)
- Government action (e.g. government franchise)
- Increasing return to scale (natural monopolies, e.g. public utilities)
What is a cartel?
A cartel is a group of firms that conspire to make price and output decisions for a product or service; it is a overt collusion and illegal
What is collusive pricing?
When a few firms in an oligopolistic market conspire to set the price at which a good or service will be provided. Such collusion typically is carried out to establish a price higher than would exist under normal competition
What are leakages?
The amount of individual income that are not spent on domestic consumption (taxes, savings, imports)
What are injections?
Amounts of expenditure not for domestic consumption added to the domestic production (government spending, subsidies, investments)
What is the aggregate demand curve?
Measures the total spending of individuals, businesses, governmental entities, and net foreign spending on goods and services at different price levels. The demand curve is negatively sloped
What are the components of aggregate demand?
- Consumer spending
- Investment
- Government Spending and Fiscal Policy
- Net Exports/Imports
What is the formula for Marginal propensity to consume (MPC)?
