Growth of Money Supply

Description

Growth of Money Supply Data.

Usage

data(growthofmoney)

Format

A multivariate quarterly time series from 1970(2) to 1974(4) with variables

TG1.TG0

AG0.TG0

difference of actual growth rate and target growth rate for the preceding period.

Source

The data was originally studied by Hetzel (1981), the data set is given in Krämer and Sonnberger (1986). Below we replicate a few examples from their book. Some of these results differ more or less seriously and are sometimes parameterized differently.
