Some Depressing Economic Analysis

Hat tip to both Mark Thoma over at Economist's View and Paul Krugman on this study. Economists Kevin Eichengreen and Kevin O'Rourke have some data looking at the global economy and argue that:

the world economy is now plummeting in a Great-Depression-like manner; 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.

They also point out that the commonly cited comparisons that see the crisis as less severe than the Great Depression are focused on the U.S. only.

More from Eichengreen and O'Rourke:

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.

Similarly, while the fall in US stock market has tracked 1929, global stock markets are falling even faster now than in the Great Depression (Figure 2). Again this is contrary to the impression left by those who, basing their comparison on the US market alone, suggest that the current crash is no more serious than that of 1929-30.

Another area where we are “surpassing” our forbearers is in destroying trade. World trade is falling much faster now than in 1929-30 (Figure 3). This is highly alarming given the prominence attached in the historical literature to trade destruction as a factor compounding the Great Depression.

It’s a Depression alright

To sum up, globally we are tracking or doing even worse than the Great Depression, whether the metric is industrial production, exports or equity valuations. Focusing on the US causes one to minimize this alarming fact. The "Great Recession" label may turn out to be too optimistic. This is a Depression-sized event.

That said, we are only one year into the current crisis, whereas after 1929 the world economy continued to shrink for three successive years. What matters now is that policy makers arrest the decline.

More here on the policy response, which the authors argue is superior to that of the Great Depression, but, as all things policy go, uncertain to work. Krugman writes: Knowledge is the only thing standing between us and Great Depression 2.0.
