Many economists say we are not in a Depression, but a post from Eichengreen of UC Berkeley and O’Rourke of the Trinity College Dublin called A Tale of Two Depressions in the VoxEU blog showed we just might be seeing statistics worse than in the 30s. Re-posting most of what they have there:
[W]hen 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.

After showing that, we might be quick to conclude that what we have is indeed a Depression. Yet with only one year into this crisis, we can only say so much. The main difference I suppose comes from the policy responses that have come out of Washington, then and now. In considering both, we can and should expect at least a different outcome than in the past. Again, graphs from the Eichengreen-O’Rourke post:
Figure 4 shows a GDP-weighted average of central bank discount rates for 7 countries. As can be seen, in both crises there was a lag of five or six months before discount rates responded to the passing of the peak, although in the present crisis rates have been cut more rapidly and from a lower level. There is more at work here than simply the difference between George Harrison and Ben Bernanke. The central bank response has differed globally.

Figure 5 shows money supply for a GDP-weighted average of 19 countries accounting for more than half of world GDP in 2004. Clearly, monetary expansion was more rapid in the run-up to the 2008 crisis than during 1925-29, which is a reminder that the stage-setting events were not the same in the two cases. Moreover, the global money supply continued to grow rapidly in 2008, unlike in 1929 when it levelled off and then underwent a catastrophic decline.

Figure 6 is the analogous picture for fiscal policy, in this case for 24 countries. The interwar measure is the fiscal surplus as a percentage of GDP. The current data include the IMF’s World Economic Outlook Update forecasts for 2009 and 2010. As can be seen, fiscal deficits expanded after 1929 but only modestly. Clearly, willingness to run deficits today is considerably greater.

Perception has changed and so has the belief of what should be done. I’d be surprised if despite the efforts, the first set of graphs above continue to follow the direction followed in the 30s.
