The UK nominal wage growth has a long way to go yet

A James Alexander post

UK nominal wage growth figures today showed that the encouragingly upward trend of the last few months has somewhat stalled. 2.4% on a rolling 3m YoY basis is OK but nothing to get excited about, and it certainly hasn’t lasted anything like long enough. At the moment it is a flash in the pan. It may remain just flash in the pan if the Bank of England remains hovering over the pan with its fire blanket ready to snuff out anything approaching … what percentage growth rate exactly? What is the science behind the fire blanket? There is very little.

Governor Carney has indicated a few times that active money tightening is just a few months away. Why? What is the science behind his constant harping on about the need to actively tighten soon? There is nothing there apart from ingrained caution grounded in nothing.

Strong wage growth is a good thing. There, I’ve said it. He and the Bank have to demonstrate how a nominal wage growth at the heady heights of 4% in the noughties caused any serious inflation or even economic damage. It didn’t. However, fear of headline inflation above 3% did cause some serious economic damage going into the Global Financial Crisis.

Benjamin Cole has argued on this site for 6-7% NGDP targets. This may seem extreme but then there are good grounds for such a target, not just because of catching up with the growth path of the past, the “Level Targeting” part of Inflation or NGDP Level Targeting.

Strong grounds for a high rate of NGDP growth also come for the argument that only 5% nominal wage growth or more can provide the whole economy with the sort of micro-level flexibility needed to efficiently allocate labour supply. One of the principle obstacles to efficiently allocating labour is downwardly sticky nominal wages. In a recession it is downwardly sticky nominal wages that leads to mass unemployment as employers almost always have to cut staff to bring costs into line with lower revenues.

In some macro models this can cause liquidity traps and Keynesian downward spirals. We have all known that monetary policy can be loosened via interest rates to prevent this tragedy, and we now have proof that even if at the Zero Lower Bound monetary policy can still be loosened by QE and other unorthodox programmes. Top macroeconomists have known for many years that the theory of QE should work, but it hadn’t been used much at all until the last few years. Thankfully, there is no liquidity trap – just incompetent central bankers.

Downwardly sticky wages aren’t only important in a crisis but in a recovery and normal times too. A simple thought experiment illustrates the point.

If average whole economy wage growth is 5% then we can assume that there is a spread of wage growth between 0% (the sticky wages lower bound) and, say 10%. Some people, skills, experience, industries, regions will be getting nearer 10%, some nearer 0%. Labour will be moving around, more or less, to the more highly remunerated areas, sometimes merely by learning new skills, sometimes by physically moving. This is a good thing and means the economy can grow into new areas, often yielding the elusive productivity growth.

If average nominal wages are growing at just 2.5% then the lower bound is still going to be the 0% but the upper bound gets similarly restricted since the overall economy is straight-jacketed by the 2.5% wage growth. Not that many can get the 5-10% increases, because of the maths of the 2.5% whole economy rate of growth. The corollary is that the economy as a whole is less flexible, less able to allocate labour resources efficiently.

As we know, our current crop of central bankers and consensus economists think virtually any nominal wage growth a bad thing, hence the hovering fire blanket. The fear of the fire blanket will, with rational expectations, lead to fewer fires, less economic growth. Maybe that’s what the consensus of experts wants, but it can’t be what the mass of the population wants. The inflation target of 2% should be ditched now, in favour of a growth-inducing NGDP Level Target of at least 5%, but 6 or 7% for a few years to make up for lost ground, lost generations – generations turning to left and right wing populism doomed to failure.

  1. I hoist a brew to James Alexander.
    And not only wages – – I suspect bottlenecks emerge in various parts of the economy whenever there is robust growth. Those bottlenecks send out price signals and are solved through the price signal by grabbing more resources.
    And remember: Milton Friedman bashed the US Federal Reserve for being too tight when inflation was at 3%. That was 1992.
