Just a general comment.
Economists bicker all the time about IS-LM, DSGE, and every single other tool in use to attempt to understand the economy as a whole. I’m just continuing in that hallowed tradition, just trying to say I’m not a huge fan of IS-LM because it’s easy to misunderstand. But I shouldn’t complain. There are plenty of worse models out there.
From my perspective?
Making a big fuss for the next couple decades until the target is changed.
It helps to keep in mind the history of the Fed. When Johnson pushed, the Fed caved and printed too much. When Nixon pushed, the Fed caved and printed too much. Carter appointed Volcker, but when the screws started to tighten, Carter got cold feet and the Fed complied with the wishes of the president. Independent? Supposedly, but they always used to bend on command. Even when they shouldn’t have. For that reason, among others, the cult of the independent central bank really got its wind from the 80s, and nobody has pushed against them in the US since then.
Times have changed, I know, but we’re now in a situation where money is too tight, by nominal spending standards, and historically a pushy president always got what he wanted. I say to Obama, he should get his shoving gloves on.
Short- and medium-term, I don’t see a lot of danger from more debt. I just see it as suboptimal, and it strikes me that convincing a single committee would be easier than convincing a large group of short-sighted legislators, whose chances of keeping their jobs would be higher if they continue blocking every position Obama proposes.
I don’t see any real hope on any path, but the Fed is the best bet, in my estimation, both economically and politically.
