It's great there isn't a "consensus" between economists, otherwise if that consensus was wrong we would never be able to leave it, like what happens in other sciences.

Yes, it really would be terrible if economics ended up like physics or chemistry, where consensus results in vast numbers of useful and correct predictions.

"Economics is a highly sophisticated field of thought that is superb at explaining to policymakers precisely why the choices they made in the past were wrong. About the future, not so much." -- Ben Bernanke, 2013 (the quote is from an unexpectedly funny and thoughtful commencement speech) https://www.youtube.com/watch?v=Ww6guPQsKQo http://money.cnn.com/2013/06/02/news/economy/bernanke-prince...

Hey, there is a great cartoon about that here!

Yeah, well, hold on to your hat.

Japan style stagnation seems like the most likely outcome to me, what's your prediction?

Not the parent, but if I had to guess, the current administration is creating the context for a massive wealth transfer using deregulation following a financial collapse of similar magnitude to Russia in the 90s. The end aim is to create a economically and politically entrenched kleptocrat class and a corresponding "managed democracy." Funnily enough, Abe Shinzo and his political allies have suggested doing this explicitly through constitutional reform, Japan being so steeped in corruption at this point that such talk is par for the course [0].

I'm not sure what will be the trigger, they seem to be pushing at several angles - war, knock-on effects from environmental collapse, another financial implosion. Because of the systemic corruption of the Democratic Party, the collapse could emerge organically. Obama really only papered over the root causes of the financial crises (not to mention paying off the culprits).

But it's a unlikely you're going to see Japanese style stagnation. Their economic circumstances are a result of the U.S. propping up their economy through an export regime for the sake of regional national security, as well as an economic approach that (generally) pursues a more stable state than dramatic rises and falls. The U.S has neither of those preconditions. Contemporary Russia is probably more instructive generally, with perhaps Central American style inequality being exemplary for the coastal regions.

Why not? Minimising these impacts it's about finances, not economics. I.E Economics is about predicting these things (which they absolutely didn't), finances is about putting mechanisms in place so that if they happen they will be minimised.

The vast majority of economics is not macroeconomic forecasting. That's somewhat akin to saying that computer science is about making email work.

Sure. But the ones that were about macroeconomic forecasting totally fucked up. That's somewhat akin to saying that the IT department responsible for managing email is about making email work. Not such an unreasonable complaint any more. Particularly galling that we had "crazy" economists claiming that we were in a massive housing bubble which we should expect to burst back in 2006, while at the same time the economists at the Fed were saying, "Look at interest rates! Now is a great time to buy a house!" and coincidentally their mates from college were selling mortgage backed securities. So really its more akin to the IT department responsible for managing the email deliberately sending Nigerian fishing scams to their fellow employees along with the public message of "No, outlook is fine, just click on anything in your inbox!"

I think you're right. The government can keep things in sort of a gentle downward glide slope by printing money as long as they don't overdo it.

There was another article on academic incentives today that referenced a wonderful quote:

"When a measure is used as a target, it ceases to be a good measure."

My impression is that economics as a whole does not understand this. When you target GDP for example, GDP ceases to be a good measure of anything. The trouble with economics as a science is that its results are used to guide the economy. This creates a feedback loop, making it essentially a self-invalidating discipline.

We have this big problem. We'll just patch over it with this other problem and call that a reasonable strategy.

I think what he's suggesting is that paying down debt through austerity can be more costly than growth, since austerity hurts growth. The trick is, where does growth come from?

The mistake there is thinking printing money brings you growth. Where has this worked?

Great Depression: industrial production in the United States declined 47 percent and real gross domestic product (GDP) fell 30 percent. In comparison 2010-2014 was a minor blip, with less than 3% GDP drop, that barely qualifies as a correction. I fear central banks have actually gotten to good at minimizing these issues as we could easily do the same thing in another 10 years, where the great depression created far m…

A minor blip where millions lost their jobs, houses, and businesses...

The hard part about economic analysis is you can never know all the variables in a dynamic system. It's a common error to summarize based on variables convenient to the theme you choose to present only to later realize your analysis should have included some fairly obvious factors.

Firstly there are two ways that money is printed.

1) Government/central bank spend more than they take in taxes.

2) Private banks make loans to private sector (biz or individuals).

Money is destroyed by government running a surplus or by loans being repaid.

Note also that for the government to run a surplus the private sector must run a deficit (decrease savings or increase borrowing) in most circumstances.

The question is where money should be created and how it should be managed and controlled.
