A US Chamber Institute for Legal Reform study by NERA finds (no surprise) that the US legal system is the most costly in the world, even when one accounts for the difference in social-insurance programs between American and Europe. Of interesting note: UK legal expenses are up 47% in the last three years, though still substantially cheaper than the US. More: Fisher @ Forbes; Sunday Times ($); related: Zywicki @ Volokh on auto safety.
I'd like to see the full report, because even the figure of an extra 1% of GDP going to excess legal expenses relative to Europe is likely an understatement. A 2011 edition of a similar report by NERA didn't include the expense of securities litigation, where much of the money goes to attorneys (and a disproportionate share of the proceeds goes to institutional investors at the expense of small shareholders). (Update: here it is, and, indeed, the 0.82 to 1.03% estimate is very definitely an underestimate.)
While the trial bar argues the expense of the liability system as a deterrent to make medicine and consumer products safer, I'm not aware of any evidence that Europe is less safe than the US. For example, though Germany has both an Autobahn without speed limits and a much higher percentage of mini cars like the "Smart," in 2005, their auto fatality rate was 7.8 deaths per billion km travelled versus 9.1 in the United States the same year. New Zealand has no medical-malpractice cause of action at all, and there is no evidence that patients there are being butchered as a result. And fear of liability and overcautious pharmaceutical regulation is likely costing lives at the margin.
