Abstract: This
study has two objectives. First, to extract a cycle from agricultural GDP.
Second, to compute the periodicity of the cycle. To achieve these objectives, a
univariate time series procedure is applied. It is found that agricultural GDP
is cyclic and that the cycle occurs every 8.25 years.
