Why financial systems need regulation - and the economic Libertarians are wrong

In yesterday's column I explained the importance of incentives to our economic system. But humans are not like rats in a laboratory responding to simple incentives like food pellets. Rather, we are complex and we relate to incentives in a subjective way.


As a result, humans are capable of misunderstanding what will happen as a result of their behavior.  A person may think:

• "if I do A then I will get B" 

but the reality might be that 

• "As long as C or D don't happen and if I do A then I will get B"

These sorts of complexities are very common, and very difficult to understand for even the most knowledgeable person. 


In the perfect world of the theoretical economist, everyone would have perfect knowledge of the system and all of the current information. If that is not hard enough, it's also assumed that everyone will make completely rational decisions.  The economist even named this perfectly rational person "homo economicus" (the economic man). Nobody has ever met him!


So, back in the real world. There is far too much data for any person to understand. There are far too many interactions for any person to grasp. And to make matters worse, some humans cheat, corrupt, steal or are simply unskilled at their jobs.


And this is why financial systems need effective regulation - our markets just are not transparent enough. It's simply impossible. 


The free market libertarians reading this are jumping up and down right now in outrage. They want an unfettered system where the market will regulate itself. I'm sorry, but it is just a bad idea. 


To support my case, take a look at the Australian and US financial regulation systems.  In Australia, the system is regulated by the "three peaks" - ASIC, APRA and the Reserve Bank, in concert with the Treasury.  In the US, the system is regulated by a disconnected collection of state and federal bodies.  As a result, all of the Australian financial system is effectively regulated.  That includes banks, other mortgage providers, public companies, property markets, insurance companies... Whereas in the US, the regulations are looser, with many gaps.

If regulation is unimportant, and the market can self regulate, then it shouldn't matter.  But it does. Take a look at how the sub-prime housing market was able to get out of control in the US, compared with Australia. Over 14% of mortgages in the US were sub-prime at the peak in 2006, whereas Australia had around 1%.

And then, what happened next? The loans went very bad in the US, and kick started the global financial crisis. As there weren't so many of them, they didn't go nearly so bad in Australia.

Unfortunately, around the world there are many more examples of financial systems suffering due to poor regulation.  Another great example has been the failures in the Irish system, resulting in frauds, overcharging of consumers and bank bailouts by the public.


So, what's this got to do with ordinary people, incentives and the free market?

Well, "If I am confident that C or D won't happen, I will try to do A so I can get B".

But if I can't trust the system, because nobody understands the rules or plays by the rules, it will provide me with an incentive to abandon the system, and do something else, outside the legal, free market.

Effective regulations in our financial system are good for everyone. Letting the free market run wild is not.

Let me know what you think
