OK, in an earlier thread I promised that I would post about the benefits/costs of regulation. I am doing this because it seems that there are some arguing for near-total regulation (planned economy) and some arguing for the near dismantling of all kinds of regulation. You know who you are.
Marginal Costs and Benefits
First, a concept. For the benefit of those who aren’t economists and also for those who may have forgotten:
Marginal costs are the infinitesimal extra costs (be they wealth or utility) incurred when output increases infinitesimally.
Marginal benefits are the infinitesimal extra benefits (be they wealth or utility) incurred when output increases infinitesimally.
If you have a problem with ‘infinitesimal’, instead think in terms of how many units of utility are added for one extra unit of output.
Suppose marginal benefits are larger than marginal costs. Then if output is increased by one unit, utility has a net increase. This is good. We should therefore increase output.
Suppose marginal costs are larger than marginal benefits. Then if output is decreased by one unit, utility has a net increase. This is good. We should therefore decrease output.
The optimal situation then is one for which marginal costs = marginal utility.
What is the point of this? Well regulation has marginal costs and benefits too. The optimum level of regulation is that for which the marginal costs and benefits are in synch.
Personal philosophy affects to what extent you believe the marginal costs and benefits exist and how strong they are. Clearly Oldscratch will end up firmly on the side of lots of regulation, Libertarian on the side of little. My aim with this is just to clarify.
Anyhow, on with the benefits:
Benefits of Regulation
[ul]
[li]Confidence is key to our financial system. There is always the risk of wholesale collapse of faith resulting in economic ruin. Regulation seeks to ensure that failure of one participant in the market does not threaten the whole system. Parties therefore have increased faith in participating.[/li]
[li]Asymetric information – particularly in retail markets (individuals rather than institutions). If suboptimal choices are made then we have an inefficient allocation of financial resources. This is particularly important when the choices have significant impact on the future economic welfare of individuals (think choices about investment, life assurance, pensions). A regulator can insist on full information disclosure in an understandable form.[/li]
[li]Conflicts of interest – regulation enforces ‘Chinese walls’ to stop insider information giving unfair advantage (which would cause loss of faith in the system).[/li]
[li]Negotiation – individuals are weak compared to institutions. Regulators can redress this balance, for example by insisting on price controls, regulation of selling practices, right to terminate agreements, cooling-off periods etc.[/li]
[li]Capital adequacy – (for those into Captial Asset pricing theories, this is the reduction of systematic risk). Regulation can ensure that institutions hold sufficient capital to cover their liabilities. I’m thinking in particular here of the insurance and pensions industries.[/li]
[li]Competence and Integrity of financial practicioners – Regulators will insist of qualifications and membership of a professional body and prevent and individual from working in a particular industry if they are not ‘fit and proper’ to hold that position.[/li]
[li]Compensation schemes – Regulators can insist companies pay into a central fund for compensation of those who suffer due to company failure.[/li]
[li]Stock exchange requirements – Regulator will insist that companies fulfil entry and stability criteria and give disclosure. Individuals can then invest with the confidence that the company is being monitored for wrong practice.[/li]
[li]other – market should be transparent, orderly and provide protection from disaster in the case of failure by a third party.[/li][/ul]
Phew! Well that covers the benefits. Each of the above helps to increase utility. How about the costs?
Costs of Regulation
Direct Costs:
[ul]
[li]Regulation costs money. The regulator incurs considerable costs in regulating the system[/li]
[li]Companies incur considerable costs ensuring that they comply with the regulations.[/li][/ul]
The above results in higher taxation and higher fees for consumers.
Indirect Costs:
[ul]
[li]Investors and consumers may suffer a reduction in the level of care they take with respect to their choices, eg of their financial services provider. Protection reduces adverse consequences of bad decisions.[/li]
[li]There is an undermining of the sense of professional responsibility amongst intermediaries and advisers – “if my advice is bad then they’ll still be okay”[/li]
[li]There is a reduction in the consumer protection mechanism developed by the market itself. The idea that alienating your consumers is bad business practice, so the market would develop its own (possibly more efficient) checks and measures.[/li]
[li]Reduced product innovation – companies must comply with regulation; they may be worried that new products will not stand up to this or may be unprofitable because of it.[/li]
[li]Reduced competition – regulation is a constraint on the market and causes a barrier to entry.[/li][/ul]
The above indirect costs are all examples of moral hazard – a change of behaviour for the worse due to knowing that the consequences have been dulled.
Summing up
Firstly, apologies for the length of this post. I hope however that I have helped to identify the playing field, if not the goalposts. Additions/refutations/comments are of course welcomed.
