The chapter presents an alternative framework to analyze the way in which inflation targeting works in a small open economy. The new monetary consensus revolves around a model of ‘inflation targeting’, which is concerned with coordination and the compromise of the Central Bank (CB) to strive for one particular rate of inflation. That orthodox model can be reduced to three equations: the first is a sort of IS curve; the second is a sort of Phillips augmented expectations model; and the third might be something like a Taylor rule.1 Information and compromise presumably create a more transparent framework, reducing discretion through a reference price: i, the rate of interest.
