Usually when you hear discussion of what's described as the economic impact of civil litigation, you're hearing a political discussion, in which one side or the other is complaining about what it calls frivolous cases. More often than not, these "frivolous" cases turn out to be not frivolous at all, but cases which the complaining side has lost, or is about to lose.
That having been said, the costs of civil litigation vary tremendously by type of litigation and by location in which the litigation takes place.
You'll find that business organizations, such as the Chamber of Commerce, will have well written explanations of why the costs are in their view too high...and lawyers' organizations explaining that access to the law, and litigation, benefits everyone, because it helps level the playing field, protecting both the large and the small from infringements on their rights and damage caused by those who without litigation would be unchecked in their ability to harm others.
