# Some problems with taylor rules

Moreover, I think even the ardent rules supporters have in mind some flexibility to deal with temporary exigencies. Does the regression reveal the Taylor rule that the Fed is following?

That this rule took so long to develop should be a source of both embarrassment and epistemic humility for economic policy makers. But if agents are heterogeneous along any or all of the above lines, any economy-wide value for the rate of time preference will vary, among other things, with the prevailing distribution of income and wealth, and will therefore vary with the structure of relative prices. Inflation targeting can do a better job of dampening shocks to aggregate demand than of dampening shocks to aggregate supply. The Taylor Rule offers a guide to setting this target in a way that simultaneously keeps inflation in check and dampens the business cycle. I especially recommend Marvin Goodfriend's paper, which I'll try to blog at some point in the future. Under the Taylor Rule, however, the structure of production is perceived to be in perfect shape. And if it uses expected inflation, which of the alternative methods of measuring inflationary expectations should it choose? This dilemma bedeviled monetary policy until the work of Milton Friedman and the Great Inflation of the s brought widespread acceptance of the Fisher effect.

Despite these empirical obstacles, direct targeting of nominal GDP at least does not necessarily require any static assumptions about the unobservable natural interest rate. For example, fifteen years ago, the Consumer Price Index CPI calculated inflation to be about 3 percent higher per year than it does today.

Footnotes 1. And if it uses expected inflation, which of the alternative methods of measuring inflationary expectations should it choose? Some have now gone so far as to propose legally binding the Fed to this kind of feedback rule.

Under a free market economy, the crisis would fix itself as the excess employees in the service industry made their way to the manufacturing sector. Posted by.

### Taylor rule derivation

This dilemma bedeviled monetary policy until the work of Milton Friedman and the Great Inflation of the s brought widespread acceptance of the Fisher effect. That is not what anybody has in mind, obviously. The new-Keynesian model is an extreme case of this behavior, in which the right hand variable and error terms are perfectly correlated. Suggested Citation. I am left with more questions than answers, which is good. David Papell's presentation and Monika Piazzesi's comments were very thought-provoking in this regard. Real rates are the rates we compute by adjusting either ex-post for actual inflation or ex-ante for anticipated inflation. After justifying the dynamic IS and explaining the logic of this rule in detail, the paper compares the Tracking Rule with the Taylor Rule, simulating both of them in the context of different types of shock in the modified three equation model. The results show that, with the same shock, the economy is more likely to fall into the liquidity trap when the Taylor Rule is applied. But locking the Fed into some kind of interest-rate rule based on questionable assumptions would be a step in the wrong direction. In fact, it is nearly impossible to accurately compute the two pieces of economic data — inflation and potential output — that this formula is dependent upon. Our objective is to propose an alternative to the Taylor Rule which overcomes both problems. So is there anything but rules based policy? In David's regression, we can ask the question: Embed the rule in a model. Although economists disagree about the magnitude, extent, and duration of the liquidity effect, the bottom line is that the initial impact of monetary policy on interest rates is self-reversing.

This is deep. In the new-Keynesian model, the answer is no.

## Taylor rule supply shock

While following this rule may, in some isolated cases, generate marginal improvements to economic data, we need to ask ourselves if we want the economy to progress or to be cured; and we need to ask ourselves if we want an economy that is better overall or better for everyone. Despite these empirical obstacles, direct targeting of nominal GDP at least does not necessarily require any static assumptions about the unobservable natural interest rate. Does the regression reveal the Taylor rule that the Fed is following? As mentioned above, they indirectly target nominal GDP. Framed that way, I think one answer is before us. Economic volatility causes estimated Taylor Rule residuals, not the other way around. At best, forward guidance amounts to a set of promises that the Fed will feel it somewhat costly to renege on.
