The events aren't intended to dominate the game. Well, except for the Fundies, who can wipe out whole empires nonsensically with one roll of the dice.
+9 research is as good as one of the stronger starbase modules, and almost equal to a trade good. How is that not significant? Only if I have a few research starbases fully mined does it seem irrelevant to me. Of course, later in the game, the alignment shift usually matters more than whatever the cost or benefit may be. Usually.
I have always gone for the econ ability because it's 100% right off the top.

It's also useless in the late game, since income per planet is capped, and there are other ways to boost economy: resources, wonders. By contrast, +trade continues to increase income, although it requires you to remain at peace with at least one partner and protect the trade routes dilligently.
+Econ helps out more, the more planets you have. Econ is a strong ability on Abundant maps, but chiefly irrelevant on rare.
