Secular stagnation or secular boom?

The notion that some countries are caught in a long and protracted period of low growth has received an increasing amount of attention and has been labelled "secular stagnation". The pessimism that the idea of secular stagnation has created has been reinforced by the notion the potential for emerging markets to grow is becoming weaker. The point that I want to make in this post is that one of these notions (secular stagnation) is looking backwards at the performance of advanced economies while the other one (potential pessimism about emerging markets) is looking forward and speculating with their inability to do as well as in the last decade.

Let's start with a simple chart that summarizes the pattern of annual growth in the world over the last decades. Data come from the World Economic Outlook database (IMF). I have decided to include the last 13 years for the decade that starts in 2000.















Two observations: growth (by decades) has been remarkably stable in the world, between 3.2%-3.6%. Second observation: during the last 13 years growth has increased relative to the previous two decades. No global stagnation, if any, acceleration of growth.

But if we split the world into advanced and emerging markets we see a very different pattern. [I will use the label emerging for any country which is not advanced - the IMF will call them emerging and developing countries].















While in the 80s, and some extent in the 90s, both groups grew at a very similar rate, in the last 13 years annual growth rates in emerging markets have been three times higher than those of advanced economies. So stagnation might be the right label for 50% of the world, but accelerating growth is the right label for the other half.

And if we look at the engines of growth, in particular investment rates (in physical capital) we can see again the divergence in performance.
















Investment rates for the world are fairly stable over all these years with possibly some mild increase in the last 13 years. And that increase is driven by an explosion in investment rates in emerging markets (by 50%) at the same time that investment falls in advanced economies below the 20% level.

Looking at the above charts, one wonders whether the divergent performance of emerging markets and advanced economies is related. Could it be that investment opportunities in emerging markets moved capital away from advanced economies? Not obvious because we know that the explosion in investment rates in emerging markets came in many cases with even larger increases in saving rates and (financial) capital flew away from these countries. In fact, interest rates in the world were trending downwards during this period. And this makes the performance of advanced economies even more surprising: despite a favorable environment in terms of low interest rates, investment and growth declined.

What Happens When You Drink Enough Water

Tridona Bestsellers If you’re reading this: Drink a glass of water. You likely need it, as 75 percent of Americans are described as “chronically dehydrated.” While achieving a state of hydration might seem enviable and impossible, fret not because it’s doable. And the health benefits are not only encouraging, but they are also downright inspiring in the immediate short term, but especially in the long run. “Long-term hydration is the single best thing we can do to prevent chronic illness,” says Dr. Dana Cohen, an integrative medicine specialist in New York and coauthor of Quench: Beat Fatigue, Drop Weight, and Heal Your Body Through the New Science of Optimum Hydration . Though the eight-cup rule is popular, there is no one-size-fits-all number. Instead, it’s more of an individual approach. The new general rule of thumb is half your weight in ounces, according to Dr. Cohen. For example, if you weigh 120 pounds, you need to drink 60 ounces of water a day.

The permanent scars of fiscal consolidation

The effect that fiscal consolidation has on GDP growth has probably generated more controversy than any other economic debate since the start of the 2008 crisis. How large are fiscal multipliers? Can fiscal contractions be expansionary? Last year, Olivier Blanchard and Daniel Leigh at the IMF produced a paper that claimed that the IMF and other international organizations had underestimated the size of fiscal policy multipliers . The paper argued that the assumed multiplier of about 0.5 was too low and that the right number was about 1.5 (the way you think about this number is the $ impact on GDP of a $1 fiscal policy contraction). While that number is already large, it is possible that the true costs of fiscal consolidations are much larger. In a recent research project (draft coming soon) I have been looking at the effects that fiscal consolidations have on potential GDP. Why is this an interesting topic? Because it happens to be that during the last 5 years we have been seriously re...

The permanent scars of economic pessimism

Gavyn Davies at the Financial Times reflects on the growing pessimism of Central Banks regarding the growth potential of advanced economies. In the US, the Euro area or the UK, central banks are reducing their estimates of the output gap. They now think about some of the recent output losses as permanent as opposed to cyclical. It output is not far from what we consider to be potential, there is less need for central banks to act and it is more likely that we will see an earlier normalization of monetary policy towards a neutral stance. Why did they change their mind? Is this evidence consistent with the standard economic models that we use to think about cyclical developments? Measuring potential output or the slack in the economy has always been challenging. One can rely on models that capture the factors that drive potential output (such as the capital stock or productivity or demographics) or one can look at more specific indicators of idle capacity, such as capacity utilization or...
