The following table examines intertemporal versus interspatial comparison in PPP calculation/index number theory. In particular, aspects of intertemporal comparisons have counterparts in interspatial comparisons, so the table catalogs these.
Comparison table
| Aspect | Intertemporal | Interspatial |
|---|---|---|
| How well the weights match the thing being compared[1]Template:Rp | Up-to-dateness | Characteristicity |
| Tendency of Paasche quantity indices to be lower than Laspeyres indices[2]Template:Rp | Gerschenkron effect | Own-weight effect |
| Ordering | Natural ordering by year (or other granularity of time periods) | No natural ordering (but some have devised orderings) |
