How the Fed Came to Be
Tuesday, November 1, 2011
NGDP Targeting, the "Volcker Moment", and Chuck Norris
did not succeed by changing people’s expectations of inflation. It succeeded by crushing demand. As unemployment moved up the Phillips Curve, inflation plummeted. Only then did inflation expectations stabilize at a lower level.... The lesson of the Volcker disinflation is that changing expectations depends crucially on delivering on the target. Naming an inflation or money supply target is helpful, but insufficient unless the central bank demonstrates it is willing and able to achieve it.That statement reminded me of this post from Worthwhile Canadian Initiative:
Thesis. We teach the monetary policy transmission mechanism like this: the central bank pulls a lever, and that lever pulls other levers, which eventually move the target variable in the direction the central bank wants to move.Basically, in order for Chuck Norris to impact behavior, people have to think he'll kick their ass. The central bank (Fed) has to convince people that it's going to do what it says it intends to do when circumstances dictate. In other words, every now and then, Ben has to kick some ass. If you want higher NGDP, you can't make it happen by standing in the room looking tough. You have to actually break a few skulls.
Antithesis. That's wrong. A credible central bank is exactly like Chuck Norris. It looks at the thing it wants to move, and the thing moves, and all the other levers fall into place where they should be. Causation runs backwards from the target variable. Credible central banks don't actually do anything. They just threaten to do things. But a credible central bank never needs to carry out its threats.
Synthesis. That's not quite right either.
1. Even Chuck Norris can't make the impossible happen. A credible central bank can move the economy just by saying that it wants the economy to move. But it must be a new equilibrium that it moves to. And maybe that new equilibrium won't be an equilibrium unless the central bank moves its lever. Chuck Norris can't clear the room if he is standing in the only doorway. He has to step aside to let people exit, even if he doesn't need to throw anyone out.
2. Chuck Norris wasn't always Chuck Norris. He had to earn his reputation. In the early days, or in unfamiliar territory, he actually had to carry out his threats. Till people learned the new regime.

How the Fed Came to Be (and Why it Must Remain Independent)
Early efforts to reform the financial system were limited to the First and Second Banks of the UnitedSo, you might say, we should just put central banking under direct control of the government. How wonderful and democratic that would be! Do that, and I can almost guarantee higher rates of inflation as Congress has the incentive to use the money supply to "monetize" its deficits and debt.
States (1791-1811 and 1816-36, respectively). Both institutions were short-lived because of public misgivings
about concentrated economic power. A period of laissez-faire (or free-market) banking followed, rife with
flawed banking practices and instability. In 1863 and 1865, Congress enacted the National Banking Acts
to stabilize the financial system. Without a central bank, however, problems remained—financial crises and
banks failures continued to be frequent and severe. Two characteristics of the National Banking System (NBS),
created by the 1863 Act, exacerbated this volatility: (i) immobile bank reserves in a system lacking a lender
of last resort and (ii) an inflexible supply of currency. [Emphasis added.]

The Best Description of the 2011 Nobel Laureates' Work so Far
[In response to the Lucas Critique] Sargent’s (1973, 1976) early work showed how models incorporating rational expectations could be tested empirically. In many of these early models, Sargent showed that including rational expectations in a model could lead to invariance results, nominal shocks caused by changes in the money supply, for example, wouldn’t matter.I was never comfortable with the simple RE approach (and hated being forced to study it in grad school), which is why I'm glad AT mentions some of Sargents more recent work:
What will people do when they don’t know the true model of the economy? How will they update their model of the economy based on observations? In these learning models the goal is to look for a self-confirming equilibrium. The interesting thing about a self-confirming equilibrium is that people’s expectations and learning can converge on a false model of the economy!On Sims:
In response [to the Lucas Critique], he developed vector auto regressions. In its simplest form a VAR is just a regression of a variable on its past values and the past values of other related variables. It’s easy to run a VAR on unemployment, inflation and output, for example.... Sims, however, took the models a step further by showing that you could identify fundamental shocks in these models by making assumptions about the dynamics or ordering of the shocks. ... With identification in hand one can then use these models to plot impulse response functions. How does a shock to oil prices work its way through the economy? When does GDP begin to fall and by how much? How long does it take the economy to recover? What about a shock to monetary policy? Sims (1992), for example, looks at monetary shocks in five modern economies.

It's a liquidity trap
From Modeled Behavior:
In some cases people suspect that the Central Bank will vacuum up
every single dollar it dropped. In those cases, the dropping doesn’t
make anyone happier because they are just going to get hurt again by the
exact same amount.This is a liquidity trap.
Hence, monetary policy won't work much, but fiscal policy has been limited by politics (in fact there has been no net fiscal policy - see here), so what can Ben do but try crazy things like the twist?

Some Links on the Recession and Response
Taxing the rich. Even if it doesn't raise substantially more income, and may have unintended consequences, redistributing from savers to spenders is probably helpful in the short run (and design matters).
Are pensions Ponzis? They need not be, but they do have Ponzi-like attributes, and it is tempting for managers to raid them (including - especially? - when they're run by "public servants").
Much ado has been made of recent upward revisions to Ireland's growth for last quarter, because they implemented austerity instead of stimulus. Problem: They're much farther behind their 2007 peak than the other developed countries that got hit.
The spending side: Biggest contributor to our deficit increase in the last 10 years; the biggest revenue contributor: the recession itself, followed by the 2001 & 2003 tax cuts.

Debt and growth according to the IMF (BBC News) My view is that it's not so much debt as political risk. In the short run, the fundamentals of our (and Europe's) economy can withstand the current levels, burdens, and rates of growth in the levels and burdens, in the debt. I also don't see specific policy "A" or specific policy "B" as being the most important thing, so much as greater agreement, consensus and confidence that policies will be stable of the the forseeable time horizon. In the long run debt does matter, but anyone who claims to be serious about controlling it must admit that three things have to be on the table: (1) taxes; (2) defense; and (3) programs for seniors.

Free Exchange on Cowen's Austrian predictions in 2005. Apparently he predicted a crisis, but not the one we got. (Noriel Roubini predicted the same crisis using more Keynesian principles!)
GDP and GDI: Which is the better measure? They should be roughly the same, with the difference being "statistical discrepancy". Basically, it's a difference that comes from differences in sample collection: firms versus households. For some reason, GDI seems to pick up turning points in the business cycle better. (links here, here, and here) Bottom line: things are still bad, but not as bad as we thought, maybe.

Summary of an interview by Felix Simon with Larry Summers. Sentences to ponder:
The Treasury bond rate, Treasury note rate for ten years is 2.85 percent. Nobody is failing to invest because 2.85 percent is too much. They are failing to invest because there are no customers in their store. They are failing to invest because their factories are sitting empty. They are failing to innovate because they’re not sure how large the market for the product will be.

Interesting
Very few countries default because they can’t afford to pay their debts, either to their own citizens or to foreigners. Defaults occur when the political process in a country determines that, for whatever reason, the government cannot raise sufficient revenue.
Interesting. It mentions the debt-to-revenue ratio as a critical factor in determining the sustainability (read: servicability) of our debt. Even with the tax-cut crazy republicans dictating the agenda, we're not at a critical level on that statistic.

Huh?
First, we have the Economist lending credibility to the idea that the "redback" might become a player as a reserve currency. I'm skeptical.
Seocnd, hedge funds are shorting China (i.e. betting on the notion that their boom is about up). On the one hand, this might be self-fulfilling; on the other hand it might explain the US-China trade deficits in terms of the standard inter-temporal current account macro model (if you expect the US to grow in the future, our running trade deficits today is optimal; if you expect China to shrink in the future, their running of trade surplusses today is optimal).
