Very nice topic. I read recently that each business regulatory reform is associated with a 0.15 percent increase in growth rate of GDP. interesting finding, http://ideas.repec.org/a/eee/jjieco/v26y2012i3p285-307.html . Certainly, as you say, business environment is key, such data and indicators are helping us in reform effort here in Ethiopia. fortunately, we have some political stability now, allowing some reforms, hoping we succeed.
