A Very Large Invisible College Indeed: Analogies to teh Great Depression

So I surf to Mark Thoma's website physically located 400 miles north of my office in order to find the smart things being written eight feet to my north, on the other side of my office wall. Barry Eichengreen:

From Wall Street to Main Street: Lessons from the Great Depression: A couple of months ago at lunch with a respected Fed watcher, I asked, “What are the odds are that US unemployment will reach 10% before the crisis is over?” “Zero,” he responded, in an admirable display of confidence. Watchers tending to internalise the outlook of the watched, I took this as reflecting opinion within the US central bank.... The Fed and Treasury were on the case. US economic fundamentals were strong. Comparisons with the 1930s were overdrawn.

The events of the last week have shattered such complacency. The 3 month treasury yield has fallen to “virtual zero” for the first time since the flight to safety following the outbreak of World War II. The Ted Spread, the difference between borrowing for 3 months on the interbank market and holding three month treasuries, ballooned at one point to five full percentage points. Interbank lending is dead in its tracks. The entire US investment banking industry has been vaporised. And we are in for more turbulence. The Paulson Plan, whatever its final form, will not bring this upheaval to an early end.... So comparisons with the Great Depression.... Which ones have content, and which are mainly useful for headline writers? 

First, the Fed now, like the Fed in the 1930s, is very much groping in the dark. Every financial crisis is different, and this one is no exception. It is hard to avoid concluding that the Fed erred disastrously when deciding that Lehman Bros. could safely be allowed to fail. It did not adequately understand the repercussions for other institutions of allowing a primary dealer to go under. It failed to fully appreciate the implications for AIG’s credit default swaps. It failed to understand that its own actions were bringing us to the brink of financial Armageddon.

If there is a defence, it has been offered [by] Rick Mishkin, the former Fed governor, who has asserted that the current shock to the financial system is even more complex than that of the Great Depression. There is something to his point. In the 1930s the shock to the financial system came from the fall in the general price level by a third and the consequent collapse of economic activity. The solution was correspondingly straightforward. Stabilise the price level, as FDR did by pumping up the money supply, and it was possible to stabilise the economy, in turn righting the banking system.

Absorbing the shock is more difficult this time because it is internal to the financial system. Central to the problem are excessive leverage, opacity, and risk taking in the financial sector itself. There has been a housing-market collapse, but in contrast to the 1930s there has been no general collapse of prices and economic activity. Corporate defaults have remained relatively low, which has been a much-needed source of comfort to the financial system. But this also makes resolving the problem more difficult. Since there has been no collapse of prices and economic activity, we are not now going to be able to grow or inflate our way out of the crisis, as we did after 1933.

In addition, the progress of securitisation complicates the process of unravelling the current mess....

That said, we are not going to see 25% unemployment rates like those of the Great Depression. Then it took breathtaking negligence by the Fed, the Congress and the Hoover Administration to achieve them. This time the Fed will provide however much liquidity the economy needs. There will be no tax increases designed to balance the budget in the teeth of a downturn, like Hoover’s in 1930. Where last time it took the Congress three years to grasp the need to recapitalise the banking system and provide mortgage relief, this time it will take only perhaps half as long. Ben Bernanke, Hank Paulson and Barney Frank are all aware of that earlier history and anxious to avoid repeating it.  

And what the contraction of the financial services industry taketh, the expansion of exports can giveth back.... The ongoing decline of the dollar will be the mechanism bringing about this reallocation of resources. But the US economy, notwithstanding the admirable flexibility of its labour markets, is not going to be able to move unemployed investment bankers onto industrial assembly lines overnight. I suspect that I am now less likely to be regarded as a lunatic when I ask whether unemployment could reach 10%.

Three points. (1) We could inflate our way out of it--in the 1930s we had a 30% product price deflation, and now we have had a 30% housing price deflation. Balanced inflation would remove the debt overhang in both cases. We may well not want to resolve the problem via inflation--and I suspect that even by raising the theoretical possibility I have reduced my chances of attaining high office in the Eccles Building to something indistinguishable from zero--but we could.

(2) Barry is right. Particularly, it looks as though Barry is right about Lehman Brothers. In retrospect, the decision to let Lehman fail without rescue, control, or supervision looks to be the first significant misstep that Bernanke and Paulson have made in the past fifteen months. Clearly it looked to them to be a good idea at the time, and clearly they have more information than I do, and it is impossible to dance this dance and put every foot right. I'm sure that had I been at the Treasury or the Fed I would have made worse mistakes by now than they have made. But:

It looks like it is the failure to cushion the losses of the creditors of Lehman than has produced the need for emergency action. If the Fed and the Treasury had offered Sunday night to buy as much of Lehman debt as the market offered at 75% of the previous Friday's market price, I don't think we would be staring into this particular abyss right now.

(3) Nevertheless, I said a year ago that if the unemployment rate stays below ten percent then it is a win for monetary policy. And I still think we have an 80% chance of achieving that...
