Not always (ain't it always the case!). Once you get into the 'in-molded' ones I reckon the protection starts decreasing as the weight goes down, air-vent count goes up.
You might get a bit more testing for the expensive ones but this is usually aerodynamic testing AFTER they've been designed to pass standards XYZ.
I recall reading about expensive helmets being more likely to cause less serious injuries like whiplash because of the sharp bits at the back digging into the ground, for example and causing some head twisting on impact. Like, my MET got a poorer mention because it has really sharp spike bits out the back which catch on stuff as you skim down the road.. twisting your neck..
I don't think safety standards take this kind of thing into account. Google for articles about helmet safety testing and comparisons..
