compression ratio and boost

I was just thinking, lower compression allows you to run more boost but will that extra boost make up the power lost from lowering the compression? how would you determine total compression? multiply compression ratio by # of atmospheres? (e.g. 9.5 compression * 1.5 bar = 14.25:1 compression) and what would give you more fuel economy, turbo or high compression with the same output? so all things being kept constant (exhaust after turbo, intake other than turbo and ic, internals, tranny and timing) what would give you better performance, the most boost you can run on pump gas or the most compression you can run on pump gas?
