The Output Gap: A “Potentially” Unreliable Measure of Economic Health?

Excerpt from a newsletter by Elise A. Marifian, Research Analyst at the St. Louis Fed, describing problems with calculation of the hypothetical output gap and how this can lead to incorrect monetary policy:

Some economists question the reliability of potential output and, therefore, output gap measures. For instance, as James Bullard noted in 2009, if calculations had considered the housing boom and bust, then potential GDP and output gap measurements would have been smaller than they appeared…….. Gavin (2012) shows that the output gap calculations for 2003-12 are reduced significantly when 2011 estimates of potential GDP are used in place of 2007 estimates. If our economy is improving faster than current output gap measurements suggest, then monetary policy intended to boost the economy could produce too much stimulation, thereby fueling inflation once the economy begins to pick up steam.

Treasury yields warn more of the same

Inflation has fallen over the last quarter-century, so one would expect to find Treasury yields have fallen, but there is more than just benign inflation at work. The Fed has also been suppressing long-term interest rates, with QE1, QE2, Operation Twist and now QE3.

10-year Treasury Yields

The yield on 10-year Treasuries is now below the Fed’s long-term inflation target of 2 percent, offering savers a negative return on investment unless they are prepared to take on risk. The Fed’s aim is to induce investors to take on more risk, in the hope that increased capital spending will stimulate employment and lead to a recovery. But they risk leading savers into another disaster, with falling earnings or rising yields ending in capital losses.

Corporations are reluctant to expand and will remain so until they see a sustainable increase in consumption. Fueled by new jobs — not short-term credit. Low interest rates without job growth could cause another speculative bubble, with too much money chasing too few opportunities.

Without jobs, no monetary policy is likely to succeed.

Australia: Falling job ads

ANZ job ads fell 4.6 percent in October after a 3.9 percent fall in September. The index is down 15 percent over the last year.

From ANZ:

“The ANZ job advertisement series measures the number of jobs advertised in the major daily newspapers and Internet sites covering the capital cities each month. It has historically proved to be a very good indicator of future labour market conditions and thus, is extensively relied upon for forecasting employment growth.”

Nationalbanken Defends Sub-Zero Bemoaned by Banks | Bloomberg

Peter Levring and Frances Schwartzkopff write that Denmark’s central bank has taken an unusual step to defend the krone from capital inflows similar to those experienced earlier by Switzerland.

The central bank has kept its deposit rate at minus 0.2 percent since July, in an effort to fight off a capital influx and maintain the krone’s peg to the euro.

Deposits held at the central bank are charged a fee of 0.2%, rather than paid interest as in the US.

At the same time, the industry is still paying its customers to hold their deposits in an effort to attract stable funding and reduce reliance on wholesale financing. That’s turned deposit banking in Denmark into a losing business.

The measure would encourage banks to increase lending, loosening credit standards to avoid the charge on excess reserves. It would also reduce the rate paid on call deposits, while increasing bank competition for more stable time deposits.

Fiscal Cliff: Two Candidates, Two Approaches

By ERIC PIANIN and MERRILL GOOZNER, The Fiscal Times

[Romney and Obama] agree that a stopgap measure is needed before January 1 to temporarily extend the raft of Bush era tax cuts and other measures set to expire. However, Obama has signaled his intent to veto even a few months’ extension of tax cuts unless families earning more than $250,000 a year are made to pay higher rates.

……. Romney, Boehner and Senate Republican Leader Mitch McConnell of Kentucky insist that the Bush tax cuts be extended for all Americans, arguing that any increase in rates would discourage investments and job expansion by small businesses. Moreover, Romney has proposed further tax cuts of 20 percent across the board in exchange for capping tax breaks……..

Twin China PMI surveys show economy perking up | Reuters

By Lucy Hornby

“The return of the PMI above 50 suggests economic momentum has indeed picked up. It indicates the effect of policy easing may have been stronger than the consensus expected,” Zhiwei Zhang of Nomura said in a comment emailed to Reuters. “We believe macro data will continue to surprise on the upside in coming months, as the government continues to ease policy through the period of leadership transition.”…….

Why the Fed should not target inflation

Scott Sumner, Professor of Economics at Bentley University, proposes that the Fed target nominal growth in GDP (“NGDP”) rather than inflation as Ben Bernanke has long advocated:

“Even he [Bernanke] must be surprised and disappointed with how poorly [inflation targeting] worked during the recent crisis.”

The primary problem, Sumner points out, is that measures of inflation are highly subjective and often inaccurate.

“The problem seems to be that, according to the Bureau of Labor Statistics, housing prices did not fall. On the contrary, their data shows housing prices actually rising between mid-2008 and mid-2009, despite one of the greatest housing market crashes in history. And prices did not rise only in nominal terms; they rose in relative terms as well, that is, faster than the overall core CPI. If we take the longer view, the Bureau of Labor Statistics finds that house prices have risen about 8 percent over the past six years, whereas the famous Case-Shiller house price index shows them falling by nearly 35 percent. That is a serious discrepancy, especially given that housing is 39 percent of core CPI……..

There are errors in the measurement of both inflation and NGDP growth. But to an important extent, the NGDP is a more objectively measured concept. The revenue earned by a computer company (which is a part of NGDP) is a fairly objective concept, whereas the price increase over time in personal computers (which is a part of the CPI) is a highly subjective concept that involves judgments about quality differences in highly dissimilar products.”

Inflation targeting also encourages policymakers to think in terms of monetary policy affecting inflation and fiscal policy affecting real growth — “a perception that is both inaccurate and potentially counterproductive”.

“Advocates like Bernanke see [inflation targeting] as a tool for stabilizing aggregate demand and, hence, reducing the severity of the business cycle. This is understandable, as demand shocks tend to cause fluctuations in both inflation and output. So a policy that avoids them should also stabilize output. I have already discussed one problem with this view: The economy might get hit by supply shocks, as when oil prices soared during the 2008 recession……..”

Linking monetary policy (and the money supply) to nominal GDP growth would offer a far more stable growth path than the present system of inflation targeting.

Global QE

Observation made by Philip Lowe, RBA Deputy Governor:

Since mid 2008, four of the world’s major central banks – the Federal Reserve, the ECB, the Bank of Japan and the Bank of England – have all expanded their balance sheets very significantly, and further increases have been announced in a couple of cases. In total, the assets of these four central banks have already increased by the equivalent of around $US5 trillion, or around 15 per cent of the combined GDP of the relevant economies. We have not seen this type of planned simultaneous very large expansion of central bank balance sheets before. So in that sense, it is very unusual, and its implications are not yet fully understood……
