Abstract

The benchmarking problem arises when time series data for the same target variable are measured at different frequencies with different level of accuracy, and there is the need to remove discrepancies between annual benchmarks and corresponding sums of the sub-annual values. Two widely used benchmarking procedures are the modified Denton Proportionate First Differences (PFD) and the Causey and Trager Growth Rates Preservation (GRP) techniques. In the literature it is often claimed that the PFD procedure produces results very close to those obtained through the GRP procedure. In this chapter we study the conditions under which this result holds, by looking at an artificial and a real-life economic series, and by means of a simulation exercise.

Footnotes
1
Empirical comparisons between the Cholette–Dagum regression-based benchmarking approach, which can be seen [5] as a generalization of the seminal contribution by Denton [6], and the Causey and Trager approach, are shown in Titova et al. [10].
 
2
For a recent survey on this issue, see Di Fonzo and Marini [8].
 
3
The median is more representative than the mean in the case of atypical values. We also calculated mean, standard deviation, minimum, and range of r 1 and r 2, available on request from the authors.
 
4
When the preliminary series were used as starting values, in 50 out of 25,000 cases (0.2%) the GRP procedure produced benchmarked series with r 2 > 1.
 
5
The index r 1 is greater than one for 488 out of 25,000 series (1,95%). The highest number of cases with r 1 > 1 (270) is observed for (σ e , μ) = (5, 0), followed by 101 cases for (σ e , μ) = (10, 0). The remaining cases are: 50 for (σ e , μ) = (15, 0), 15 for (σ e , μ) = (20, 0), 4 for (σ e , μ) = (25, 0), 20 for (σ e , μ) = (5, 15), 15 for (σ e , μ) = (10, 15), 8 for (σ e , μ) = (15, 15), 2 for (σ e , μ) = (20, 15), and 3 for (σ e , μ) = (25, 15).
