Nice observation. The correct answer from your example is below (first element in blue, second element in red):
Since 1990 the
global economy has grown more than
it did during the 10,000 years from the beginning of agriculture to 1950.
In this example, the difference is that we need simple past tense for the second element of the comparison. The first element correctly uses present perfect HAS+GROWN to communicate that the action started in the past and continues into the present (since 1990), but we cannot use present perfect in the second element because the time indicator (from the beginning of agriculture to 1950) communicates that the action is is done. The implied verb in the second element is "DID GROW" or "GREW" - both simple past tense.
It is generally okay for the verb tenses to be different so long as the verbs are supplied in each element of the comparison - for a good explanation on this topic see
