Hayek Quotes of the Day

These passages from The Road to Serfdom are my favourite from Hayek because of the allusion to the need to look at institutional solutions to problems and to be flexible about the relative merits of different institutions.

His metaphor of the gardener tending to his plants is great.

Another excellent metaphor of his of the role of public policy is that of a maintenance squad in a factory making sure everything was working well, although the maintenance squad really didn’t care what the factory was producing.

Modeled Behavior

My Hayek exposure was mostly The Use of Knowledge in Society style stuff. I am just now reading The Road to Serfdom for the first time.

While his analysis of why markets work has always been wonderful, from what I can tell his political economy seems to echo that of a distinctly left-of-center economist by modern standards.

Probably nothing has done so much harm to the [libertarian] cause as the wooden insistence of some [libertarians] on certain rough rules of thumb, above all the principle of laissez-faire.

We must save capitalism from the unconstrained free-market. Is this Hayek or Robert Reich? Hayek makes repeated reference to the fact that it is only competition as a rough principle that is to be supported. Indeed, he goes on to say

The [proper] attitude of the [libertarian] towards society is like that of the gardener who tends a plant and in order to…

Recessions as reorganisations

Most models of the shape of recoveries draw on a learning process. A long tradition in business cycle theory holds that limited knowledge of relative price changes can temporarily disrupt labour demand and supply because of errors in wage and price perceptions (Alchian 1969; Sargent 2007; Hellwig 2008).

Pricing, investment and production plans are made on the basis of incomplete and conflicting knowledge of constantly changing aggregate, industry and local conditions. Firms and workers will over- or under-supply when they misperceive wages and prices.

With imprecise information, it takes time for employers and workers to sort out temporary from permanent shifts in demand and supply, inflation-driven changes from real changes in prices and input costs, and general changes from the local changes that may be more important to particular firms. As Hayek explained in his Nobel prize lecture:

The true, though untestable, explanation of extensive unemployment ascribes it to a discrepancy between the distribution of labour (and the other factors of production) between industries (and localities) and the distribution of demand among their products.

This discrepancy is caused by a distortion of the system of relative prices and wages. And it can be corrected only by a change in these relations, that is, by the establishment in each sector of the economy of those prices and wages at which supply will equal demand.

Recoveries are shaped by the speed of entrepreneurial learning about the new labour and product market conditions, the relative cost of adjusting capital and labour rapidly or slowly and the costs and benefits of labour market search. This new learning is necessary because the old constellation of prices and wages is no longer valid.

It was a misdirection of resources brought about by the initial inflationary firm, as Hayek explained in a visit to Australia in 1950:

During a process of expansion the direction of demand is to some extent necessarily different from what it will be after expansion has stopped.

Labour will be attracted to the particular occupations on which the extra expenditure is made in the first instance.

So long as expansion lasts, demand there will always run a step ahead of the consequential rises in demand elsewhere.

And in so far as this temporary stimulus  to demand in particular sectors leads to a movement of labour, it may well become the cause of unemployment as soon as the expansion comes to an end…

If the real cause of unemployment is that the distribution of labour does not correspond with the distribution of demand, the only way to create stable conditions of high employment which is not dependent on continued inflation (or physical controls), is to bring about a distribution of labour which matches the manner in which a stable money income will be spent.

This depends of course not only on whether during the process of adaptation the distribution of demand is approximately what it will remain, but ‘also on whether conditions in general are conducive to easy and rapid movements of labour.

In a recession, employers and workers do not immediately know that demand has fallen elsewhere as well as in their own local markets and recognise the need to adjust to their poorer prospects everywhere, and it is not known how long the drop in demand will last (Alchian and Allen 1973).

The cost of learning about available opportunities restricts the speed of a recovery. Workers and entrepreneurs must gather information on the new state of demand and the location and nature of new opportunities. This information is costly and is quickly made obsolete by further changes, and the cost of acquiring information is more costly the faster the information is sought to be acquired (Alchian 1969; Alchian and Allen 1967).

The process of recovering from a recession would be a faster process if the new constellation of wages and prices that are the best alternative uses of resources was known immediately and was credible to firms and workers (Alchian and Allen 1973).

Workers and employers must first have sufficient time to discover what new knowledge they now need to know to serve their interests well, leave enough room for the unforeseeable and keep their knowledge fresh in ever-changing markets.

New wage levels must be created by workers and employers testing and retesting in the labour market the new relative scarcities of labour. Imbalances between the allocation of labour supply and demand to different firms and sectors and the new level and pattern of consumer demand are gradually remedied by changes in relative prices and wages, layoffs, business closures and job search.

Prices are a signal wrapped in an incentive. Growing demand induces higher employment and rising wages. Wages stagnate, and there are layoffs where there is an excess supply.

These changes give the unemployed an incentive to move to new uses and entrepreneurs to profitably hire the unemployed. The ensuing reorganisations are time-consuming and information-intensive because a job seeker and an employer with an apt vacancy take time to find each other.

Prices and wages must change sufficiently for firms to profitably create new jobs. New jobs require time to plan and build new job capital. This is the human, physical and organisational capital underlying a new job. There are also job creation costs when reopening existing positions that were mothballed during the downturn.

How is this to be done? Hayek explained again in 1950 in his speech in Australia:

Full employment policies as at present practised attempt the quick and easy way of giving men employment where they happen to be, while the real problem is to bring about a distribution of labour which makes continuous high employment without artificial stimulus possible.

What this distribution is we can never know beforehand. The only way to find out is to let the unhampered market act under conditions which will bring about a stable equilibrium between demand and supply.
