World Economy Falling MUCH Faster than Great Depression

World Stock Market NOW vs. THEN:

Often cited comparisons – which look only at the US – find that today’s crisis is milder than the Great Depression. In this column, two leading economic historians show that the world economy is now plummeting as it did in the Great Depression; indeed, world industrial production, trade and stock markets are diving faster now than during 1929-30. Fortunately, the policy response to date is much better.

The parallels between the Great Depression of the 1930s and our current Great Recession have been widely remarked upon. Paul Krugman has compared the fall in US industrial production from its mid-1929 and late-2007 peaks, showing that it has been milder this time. On this basis he refers to the current situation, with characteristic black humour, as only “half a Great Depression.” The “Four Bad Bears” graph comparing the Dow in 1929-30 and S&P 500 in 2008-9 has similarly had wide circulation (Short 2009). It shows the US stock market since late 2007 falling just about as fast as in 1929-30.

Comparing the Great Depression to now for the world, not just the US

This and most other commentary contrasting the two episodes compares America then and now. This, however, is a misleading picture. The Great Depression was a global phenomenon. Even if it originated, in some sense, in the US, it was transmitted internationally by trade flows, capital flows and commodity prices. That said, different countries were affected differently. The US is not representative of their experiences.

Our Great Recession is every bit as global, earlier hopes for decoupling in Asia and Europe notwithstanding. Increasingly there is awareness that events have taken an even uglier turn outside the US, with even larger falls in manufacturing production, exports and equity prices.

In fact, when we look globally, as in Figure 1, the decline in industrial production in the last nine months has been at least as severe as in the nine months following the 1929 peak. (All graphs in this column track behaviour after the peaks in world industrial production, which occurred in June 1929 and April 2008.) Here, then, is a first illustration of how the global picture provides a very different and, indeed, more disturbing perspective than the US case considered by Krugman, which as noted earlier shows a smaller decline in manufacturing production now than then.
