"what I consider to be a plausible range of economic outcomes is, at the moment, quite wide indeed"

From Felix Salmon:

"
Can We Really Guide the Economy?

Ryan Avent says that he thinks the "plausible range of economic outcomes is, at the moment, quite wide indeed", and wonders whether "the size of this conceivable range is actually reflective of potential outcomes, rather than simple ignorance":

If it seems like things could go really well or really poorly, is it because outcomes are very dependent on our actions( TRUE ) or because we have no idea what's going on( BOTH ARE TRUE )? And I suppose that if you want to understand the different approaches to policy advocated by liberals relative to libertarians, that question, and its answer, is key( HOW SO? ).

The easy answer is that this is not "simple ignorance". Studies have shown repeatedly and convincingly that the range of possible outcomes is nearly always greater than you think, not smaller. Economically speaking, actual results regularly come out quite far away from even pretty near-term forecasts, which is one reason why asking economists (or journalists, for that matter) to predict when we're going to come out of recession is an exercise in futility( I AGREE ).

On the other hand, that doesn't necessarily mean that outcomes are very dependent on our actions. What action, for instance, did we take to send the price of oil plunging by $100 a barrel in the space of a few short months? That's the kind of thing which can only happen in a highly complex and therefore wholly unpredictable system( TRUE ).

So I don't think of liberals' policy approach as being deterministic( MECHANISTIC ) -- if we do this, then the economy will do that. Instead, I think of it as working the other way around: if the economy does this, then we should do( TRY ) that. Right now, the economy is tanking( A PROACTIVITY RUN), and so we should apply a large dose of stimulus( SPENDER OF LAST RESORT ). We can't predict with any accuracy what the results will be, but there's a very high chance that they will be better than if we did nothing( WE CAN'T DO NOTHING. A PROACTIVITY RUN NEEDS TO BE STOPPED BECAUSE THERE IS NO WAY OF TELLING HOW MUCH WEALTH COULD BE LOST OR HOW MANY JOBS COULD BE LOST UNTIL IT ENDS ON ITS OWN. WE CAN'T CHANCE THAT CATASTROPHIC OF A POSSIBILITY, WHICH COULD LEAD TO SERIOUS SOCIAL DISLOCATIONS AND DISRUPTIONS. ONLY THE GOVERNMENT HAS THE RESOURCES BEHIND IT STAND UP TO A CALLING OR PROACTIVITY OR BANKING RUN IN THIS AGE. NO OTHER INTERVENTION WOULD BE BELIEVED SUFFICIENT TO STOP THE RUN. )., which is the default libertarian position."

Here's Avent on The Bellows:

"Knife Edge

Watching Obama’s speech, it occurred to me that what I consider to be a plausible range of economic outcomes is, at the moment, quite wide indeed( I AGREE ). I can envision scenarios in which recovery is fairly rapid, believe it or not( THIS IS MY POSITION ). A number of economic statistics were trending positively toward late summer of last year — before the dramatic intensification of the financial crisis laid waste to the economy. If we’re able to get banks functioning again, then a quick, large stimulus might jolt us rapidly back to something near trend growth. I can also imagine some very dire scenarios, many of which involve instability abroad and negative feedback loops to the global economic system( VERY TRUE )."

I see Mechanistic Thinking in terms of the Democratic proposals in the specificity of the amounts chosen. In other words, if we plug in this number, this will be the consequence. The usual reason seems to be that we want to replace a recent consumption figure or some number like that. I don't see the problem that way at all. To me, the stimulus is intended to stop the Proactivity Run. The amount we should spend should be enough to accomplish that, as best we can tell. It might be more than some people want or less than some people want in the end. The stimulus should be spent over two years in order to assess how it is functioning. Otherwise, why not just spend enough money to happily employ everyone. Obviously there's a limit to the sense of this amount. As well, the amount we spend could have adverse consequences by spooking our creditors. Prudence here is necessary, as well as speed. Getting bogged down in debating the enormity of the eventual size of the stimulus doesn't seem wise to me.
