To address the free rider problem and reach market efficiency, governments often intervene to ensure the provision of public goods.
There are two ways in which governments can intervene:
- Direct Provision
- Contracting Out to Private Sector
There is no clear advantage between the two methods. Governments need to do a cost-benefit analysis, to compare the Marginal Benefits (MB) of e.g direct provision of the public good to its Marginal Costs (MC).
- Direct Provision by Government:
- Governments provide public goods when private firms fail.
- The public goods are financed by government tax revenues.
Remember the concept of scarcity:
- Government tax revenues are limited, hence they need to make a choice which public goods need to be provided and in what quantities.
- Contracting Out to Private Sector:
- Governments outsource the provision of public goods to private firms.
- This will be financed again by the revenue gained from government tax.
- Private firms are often more efficient and skilled, as they operate in a competitive setting.
- This forces them to be as efficient as possible to remain in the market, which could be beneficial.
- However, private firms will only do the contract if there are profits to be earned.
- Governments lose control over the services that are contracted out.
- There are potential risks to the quality of public goods provided.
Privatization of British Railway Systems
The British Government, in 1993, in search of higher efficiency, improved service, and decreased public spending, privatized its British Rail (BR). The railway was divided between 100 firms, with train operating companies (TOCs) running specific routes, while the infrastructure responsibilities were passed on to Railtrack (later Network Rail).
- Goals of Privatization:
- Increase Efficiency
- Attract Investment
- Reduce Government Spending
- Ignite Competition
- While the privatization helped some routes to get better service and through private investments, new trains to be acquired, there were still numerous challenges:
- Rising Prices
- Quality Control
- Public Bailouts
In Summary:
- Public Goods are non-excludable and non-rivalrous.
- Consumers may choose to not pay for public goods and free ride.
- Governments have to intervene to make sure that public goods are provided, to correct market failure.
