When ignorance trumps incentives

When something bad happens it is often helpful to think about why it has happened in two ways: did someone have a reason to make it happen, or did it happen by accident? This can also be expressed in a slightly different way: were incentives to blame, or ignorance? Jeffrey Friedman and Wladimir Kraus have made a compelling argument that ignorance explains more about the world than we often realize, using the 2008 financial crisis as an example. This post is an attempt to summarise their argument.

Economists often remind us that incentives matter. Indeed this is sometimes said to be the cornerstone of ‘the economic way of thinking’. Russ Roberts gives the example of death rates on British ships bringing convicts to Australia in the 18th Century – rather than attempting to raise ship captains’ awareness of the badness of letting their passengers die, the government gave captains a bonus for every convict that walked off their ship. This was very effective.

Clearly this way of thinking can be very powerful. It is the foundation of the price system, which is the mechanism that markets use to allocate resources effectively in a world where information is dispersed: if demand for pizza rises, the price of pizza rises, giving cooks and restaurant owners an incentive to sell more pizza. It helps to explain why some people stay on welfare payments for long periods of time: the welfare money they lose when they go into work represents a significant disincentive to work. Or, if you offer something like a bailout to businesses that go bust, you reduce the incentive for them to act prudently to avoid going bust.

This last example is what is known as moral hazard. And it is a popular and compelling explanation for the 2008 financial crisis. Banks expected to be bailed out if they went bust, so they acted more recklessly than they would if they thought they would be on the line for their mistakes.

However, Friedman and Kraus argue that this popular and compelling explanation may in fact be wrong. A good way of testing it would be to compare how the bankers involved in making bad decisions acted where perverse incentives applied, and how they acted where perverse incentives did not apply.

One strong piece of evidence against the incentives narrative is that bankers seem to have acted the same way with their personal investments as they did with their business investments.

Many bankers lost a lot of money personally in the crisis because their personal portfolios were not ‘bailed out’ in the same way that their banks were. If we are to treat the ‘incentives story’ as a falsifiable proposition (as all claims about the world should be treated), this might be a fairly strong reason to disregard it.

This may be where ignorance comes in. If bankers acted the way they did because they were unaware of the risks they were taking, then we would expect their private and business investments to be pretty similar.

However, it is strange that so many bankers seemed to make the same mistake. We know that they were not acting in a neutral environment: as Friedman and Kraus have shown, regulations like the Basel accords and the US’s recourse rule directed banks to prefer mortgage debt to business debt. Other regulations directed banks to rely on the risk judgments of three specific ratings agencies, giving those agencies protection from competition.

(On the ratings agencies point, astonishingly, it seems that nobody realized that these agencies were basically protected from competition. Both bankers and regulators assumed they were being subjected to market forces, leading to everyone trusting them a lot more than they would if they knew they were dealing with protected monopolies.)

These regulations were designed to make banks act prudently: the regulators had no incentive to make banks act badly. It seems possible that they did not realize the error of their ways until it was too late. Perhaps regulatory ignorance was to blame.

It is important to stress that the regulators should not be blamed personally. They probably made the best choice they could have made given the information available to them. Rather it is the position they found themselves in that seems to have been to blame. If a single bank (or even a handful) makes a mistake, that bank will suffer but the whole sector probably won’t. It is only when a whole sector of a market (or almost all that market) makes an error that we should worry. (Incidentally, as shaky as the housing and financial sectors were, the real trouble did not begin until monetary policy tightened unexpectedly, as Scott Sumner outlined at our recent Adam Smith Lecture.)

Given ignorance, we should expect errors to take place. Because regulation necessarily applies to everyone in a market, a regulatory error affects everyone.  That may be the fundamental problem with regulation, and a reason to have a strong ‘prima facie’ objection to regulation. It is better to have one hundred firms making one hundred different mistakes that happen at different times and in different ways to one hundred firms making one single mistake that happens at the same time for everyone.

None of this implies any special knowledge on the part of firms. Indeed regulators may be much more expert than the firms they are regulating, but the danger of a collective error would still give us a reason to generally object to regulation in principle, no matter how sensible it may seem.

An alternative ‘Agenda for Hope’

Owen Jones has written a nine-point ‘Agenda for Hope’ that he argues would create a fairer society. Well, maybe. I’m not convinced by many of them. Then again, it would be quite surprising if I was.

But it got me thinking about what my nine-point agenda would be — not quite my 'perfect world' policies, but some fairly bold steps that I could just about imagine happening in the next couple of decades. Unlike Owen’s policies, few of these are likely to win much public support. On the other hand, most of the political elite would think these are just as wacky as Owen's too.

Nine policies to make people richer and freer (and hopefully happier):

1) The removal of political barriers to who can work and reside in the UK. Removing all barriers to trade would increase global GDP by between 0.3% and 4.1%. Completely removing barriers to migration, though, could increase global GDP by between 67% and 147.3%. Those GDP benefits would mostly accrue to the poorest people in the world. We can’t remove these barriers everywhere but we can show the rest of the world how it’s done. Any step towards this would be good – I suggest we start by dropping the net migration cap and allowing any accredited educational institution to award an unlimited number of student visas.

2) A strict rule for the Bank of England to target nominal GDP instead of inflation, replacing the discretion of the Monetary Policy Committee. Even more harmful than the primary bust in recessions is what Hayek called the ‘secondary deflation’ that comes about as people, fearing a drop in their future nominal earnings, hold on to more of their money. That reduces the total level of nominal spending in the economy which, since prices and wages are sticky in the short run, leads to unemployment and a fall in economic output. NGDP targeting prevents those ‘secondary deflations’ and would make economic busts much less common and harmful. In the long run, we should scrap the central bank altogether and replace it with competition in currencies (see point 9, below).

3) Significant planning reform that abolished the Town and Country Planning Act (which includes the legislation ‘protecting’ the Green Belt from most development) and decentralised planning decisions to individuals through tradable development rights (TDRs). This would give locals an incentive to allow new developments because they would be compensated by the developers directly, allowing for a reasonably efficient price system to emerge and making new development much, much easier. The extra economic activity from the new home building alone would probably add a couple of points to GDP growth.

4) Legalisation of most recreational drugs and the medicalisation of the most harmful ones. I think Transform’s outline is pretty good: let cannabis be sold like alcohol and tobacco to adults by licensed commercial retailers; MDMA, cocaine and amphetamines sold by pharmacies in limited quantities; and extremely dangerous drugs like heroin sold with prescriptions for use in supervised consumption areas. The sooner this happens, the sooner producers will be answerable to the law and deaths from ‘bad batches’ of drugs like ecstasy will be a thing of the past. Better yet, this would bring an end to drug wars like Mexico's, which has killed around 100,000 people in the past ten years.

5) Reform of the welfare system along the lines of a Negative Income Tax or Basic Income Guarantee. As it is, the welfare system disincentivises work and creates dependency without doing much for the working poor. A Negative Income Tax would only look at people’s incomes (not whether they were in work or not in work), reducing perverse incentives and topping up the wages of the poorest earners. This would strengthen the bargaining position of low-skilled workers and would remove much of the risks to workers associated with employment deregulation. Of course, the first thing we should do is raise the personal allowance and National Insurance threshold to the minimum wage rate to give poor workers a de facto 'Living Wage'.

6) A Singaporean-style healthcare system to replace the NHS. In Singapore, people have both a health savings account and optional catastrophic health insurance. They pay a portion of their earnings into the savings account (poor people receive money from the state for this), which pays for day-to-day trips to the doctor, prescriptions, and so on. The government co-pays for many expenses but the personal cost disincentivises frivolous visits to the doctor. For very expensive treatments, optional catastrophic health insurance kicks in. This is far from being a pure free market system but it is miles better (cheaper and with better health outcomes) than the NHS. (By the way, if you really like the NHS we could still call this an ‘NHS’ and still get the superior system.)

7) A school voucher system and significant reform of the state education and free schools sectors. This would include the abolition of catchement areas and proximity-based admission, simplification of the free schools application process, and expansion of the free schools programme to allow profit making firms to operate free schools. These reforms, outlined in more detail in two ASI reports, would increase the number of places available to children and increase competition among schools to drive up standards.

8) Intellectual property reform. As both Alex Tabarrok and Matt Ridley have pointed out, our IP (patent and copyright) law is too restrictive and seems to be stifling new innovation. Firms use patents as barriers to entry, suing new rivals whose products are too similar to their own. In industries where development costs are high but imitation costs are low, like pharmaceuticals, patents may be necessary to incentivise innovation, but in industries like software development where development can be cheaper than imitation, patents can be a terrible drag on progress. Tabarrok recommends that we try to tailor patent length in accordance with these differences; as a sceptic about our ability to know, well, anything, I’d prefer to leave it to private contracts and common law courts to discover.

9) Last but not least, the removal of the thicket of financial regulation and the promise of bailouts for insolvent banks. Known as ‘free banking’, this system of laissez-faire finance has an extremely strong record of stability – though bank panics still occurred in free banking systems, they were much less severe and rarely systemic. Only once the government started to intervene in the financial system to provide complete stability did things really begin to go wrong: deposit insurance, branch-banking restrictions, and other prudent-seeming regulations led to extremely bad unforeseen consequences. The financial crisis of 2008 probably owes more to asset requirements like the Basel accords, which heavily incentivised banks to hold ‘safe’ mortgage debt over ‘risky’ business debt, than anything else. Incidentally, the idea that having a large number of local banks is somehow better than having a few large banks is totally wrong: during the Great Depression, 9,000 of America's small, local banks failed; at the same time not one of Canada’s large banks failed. The small banks were more vulnerable because, unlike the big banks, they were undiversified.

Now, if only there was a think tank to try and make these dreams a reality.
