What are the 2 definitions for consumption question?
Negative Externality
Scarce Rosources
Define Negative externality
Unintended 3rd party affects of the production/consumption of a service which is a result of market failure
Define scarce resources
Road space
Fewer resources to fulfil human needs
What is the first policy?
Subsidies to public transport
Write a chain of argument for subsidising public transport
Subsidising public transport e.g trains make it cheaper to travel by train- more people using public transport- reducing the number of cars on the road- reducing congestion
Draw a supply/demand graph for subsidising public transport
Notes
What are the problems with giving subsidies?
- An increase in subsidies for public transport would decrease the budget for other services e.g. NHS (opportunity cost)
Draw a opportunity cost graph
Train companies may use subsidies to cover costs rather than reducing price and consumption
What is the second policy?
Taxation- forcing a tax on drivers within the congestion zone
Draw a demerit good graph and a graph showing the affect of a tax
Notes
Explain the 2 graphs
Drivers have to pay the SMC (social Marginal cost of driving), increasing the price level, less cars on the road as less drivers are willing to pay the charge, supply shifts left to the socially optimum level of output at Q1
What are the positives for a congestion charge?
- Since congestion charge, traffic reduced by 15% and 30% improvement on journey times according to the TFL
- Raised revenue from charge could be spent on alternatives to driving
What are the negatives of a congestion charge?
- Law of unintended consequences: Business lost as consumers go elsewhere to avoid congestion
False number plates to avoid charge.
What is the 3rd policy?
Free market= Demerit good
Draw the demerit graph or refer to fig x
notes
