Target Unit Labor Costs

Last year (here and here, with related posts here, here, here, here, here, here, and here – or just read the August 2006 archives and my post from yesterday) I suggested that the Fed should target unit labor costs. Upon additional thought, I still think so. I won’t go through the whole argument again, but I want to note a few important points:

1. I’m referring to targeting a forecast of labor costs (using a “price rule” that would correct for the failures of earlier forecasts), not trying to react to every wiggle in the reported series, which is reported with a lag, quite volatile and subject sometimes to fairly dramatic revisions. The idea is for the Fed to have a long-run stable growth rate of unit labor costs as its ultimate objective, upon which it could be judged after several years of hindsight, when the final revisions come in and the trends become clear.
   
   
2. The main purpose of this approach is to have a simple and easily understood (by the market) answer to the question of how to react to supply shocks. The appropriate response to supply shocks is a matter of great controversy in macroeconomics: should a central bank accommodate supply shocks and let the inflation rate rise temporarily in order to avoid a recession or a slowing of growth (or a boom, in the case of a favorable supply shock), or should it lean heavily against the inflationary impact (or the deflationary impact) of supply shocks in order to pursue an unchanged target inflation rate? The labor cost target settles the question: if the shock is to domestic productivity or to the labor market, then lean against the inflationary impact; if the shock is entirely outside the domestic labor market and production process, then accommodate (except to the extent that you expect the shock to have indirect effects on productivity and the labor market, such as might arise, for example, from sticky real wages).
   
   
3. If the Fed is going to adopt such a policy, now is the time to announce it – or rather, to let the idea of prioritizing unit labor costs find its way into the speeches of Fed officials, since that’s the way the Fed operates. All indications today are that we are heading directly into an unfavorable import price shock. How will the Fed react? The market shouldn’t have to make random guesses. Moreover, there is great uncertainty about the intensity of the shock, and to some extent, the direction (because oil is something of a wild card and could have a big drop in price just as easily as a big increase). We want to know now what reactions to expect when these uncertainties are resolved.
   
   
4. When today’s incipient shocks are fully realized, Fed credibility is going to be a big issue, especially with a relatively short-tenured Chairman and given the market’s response to this week’s Fed action. In the case of a severe adverse shock, if the Fed hasn’t specified in advance how it intends to react, it will face a choice between recession and loss of credibility. That’s not a situation that anyone will enjoy.
   
   
5. As the following updated chart indicates, the Fed can make a pretty good case that it has already been targeting unit labor costs since the early 1990s. (The old talk about a preferred inflation rate between 1% and 2% rings a bit hollow – in addition to being, in my opinion, a less than optimal target range for inflation. But unit labor costs have stayed pretty nicely in that range – although, in my opinion, it’s a less than optimal target for unit labor costs as well, and I would hope the Fed would go maybe for something like 2%.)

From the chart, it looks like we need a slowing of unit labor costs now to continue keeping in line with the target. But given the recent weakness in the labor market and simultaneous recovery in output growth, as well as various factors suggesting a high risk of recession, I think the central tendency of the Fed’s forecasts will be for slower labor cost growth anyhow. All in all, labor costs are still very close to the presumed target, so the priority at this point should be for maintaining stable growth rather than attacking a bulge in labor costs. (And if the Fed were to do as I prefer, and raise the target to 2%, there wouldn’t be any question.)
