Taylor-like rules tend to fall in the class of those rules that are robust. That is, they yield good results in a variety of theoretical settings. This feature is of enormous practical importance.
Given our uncertainty about the true model of the economy, knowing that systematic policy in the form of a Taylor-like rule delivers good outcomes in a variety of models means that simple, robust rules can provide useful guidance for policy. Given model uncertainty and data measurement problems, there are, of course, limitations to the use of a simple rule.
