Since the inflation vs. deflation debate rages, I want to bring a new IMF working paper by Joseph Crowley to your attention, which highlights a possible decoupling of inflation trends. On a personal level, I think there has been some decoupling on the inflation front on a relatively short term basis, however, I anticipate that there will be a re-coupling in the next few years as asset prices drive down inflationary pressure. On a longer term basis, emerging markets can face higher inflation pressures as limited domestic resources, tighter currency controls, unstable politics, etc. could provide fodder for inflation.
From the paper:
Abstract:
Inflation followed a strikingly uniform pattern in all countries of the Middle East, North Africa, and Central Asia during the period 1996-2009, falling until about 2000 and then rising. International fuel prices do not help explain this pattern. This conclusion is robust even when different cross sections of countries are tested or when different regression variables are included. The pattern of inflation is explained mainly by past inflation, the strength of the US dollar, US inflation, and—depending on the subset of countries analyzed—monetary and exchange rate policies and nonfuel commodity prices.
The paper goes on to point out some key findings:
Inflation is driven by many factors, and the interest and exchange rate policies that
central banks implement, the money supply growth that they allow, and the exchange rate
regimes that constrain them are ultimately the most important. In the MENACA region,
central bank policy decisions clearly bear significant responsibility for the reemergence of
inflation. Many countries (particularly in the Maghreb) have failed to increase nominal
interest rates in the face of increasing inflation, largely because of the constraints of official
or unofficial pegs to the US dollar. Others, including in the GCC, have increased rates in
spite of the peg, but not enough to keep up with inflation. Often the key policy decision has
been to maintain adherence to an official or unofficial peg.
But the reemergence of inflation around the world was so uniform that it is hard to
attribute it entirely to shifts in the policies of individual central banks. Meanwhile, there were
striking developments in certain global variables, particularly during the period following
2000, and it would be logical to consider global factors in any study of inflation.
Global factors may have a significant impact on inflation and this impact may have
increased in importance in recent years. Borio and Filardo (2007) argue that global factors
are important and since the 1990s have become increasingly important in determining
inflation, even replacing domestic factors in some cases. Rogoff (2004) argues that
globalization, by increasing competition, has changed the shape of the Phillips curve, making
the inflation-output tradeoff less favorable to policymakers who might be willing to accept
higher inflation in return for higher output. Other authors have similarly argued that greater
openness reduces the benefits of unanticipated monetary expansion (Romer 1993) or
otherwise has effects that make narrowing output gaps more costly in inflation terms (Razin
2004). Chen (2004) finds that openness had a downward influence on prices in the EU during 1988-2000. D’Agostino (2007) finds evidence that US inflation is more closely related to global liquidity than to US liquidity. Ball (2006), however, disputes these claims. He provides evidence that the Phillips curve has changed shape, but in the wrong direction to
support the conclusions that are drawn. He also provides evidence that US inflation is not
dependent on output in other countries.
It is hard not to notice that the comeback in inflation coincided with a sharp increase
in food and energy prices, and it is tempting to infer that these increases in commodity prices
drove the resurgence in inflation. The IMF’s April 2008 Regional Economic Outlook (REO)
for Latin America noted that “Rising domestic food prices, reflecting both sharp increases in
world commodity prices and some local supply disruptions, have been widely viewed as a
key element in the uptick in inflation.” In a cross regional paper on inflation in emerging and
developing countries, Habermeier, et al (2009) concluded that the main causes of the increase in inflation were demand pressures and commodity prices, and that the initial impact of commodity price increases was followed by second-round effects. The Economist magazine indicated in May 2008 that a main cause of higher world inflation was higher food and oil prices.
The conclusion that recent inflation has been driven by commodity prices could lead
to the hope that the recent softening in energy and food prices will bring with it reduced
inflationary pressure. The decline in the value of the US dollar has also been tied to
commodity prices and to world inflation, and this raises the possibility that the recent
strengthening of the US dollar could also reduce world inflation. In the case of the MENACA
region, the benefits of lower commodity prices may be limited. A stronger dollar may have a
more important impact.
