An Animated Argument For Congestion Pricing
In 1951, Milton Friedman coauthored a paper on road pricing. It would be a mere footnote in both Friedman's career and in the intellectual history of road pricing, if not for one sci-fi flourish: The authors propose painting radioactive material alongside expressways, so that road operators can charge drivers using car-mounted geiger counters. Obviously, this suggestion was never heeded, but it says something about the economics profession’s hunger for pricing roads that a future Nobel laureate would set his imagination to Bradbury mode to advance the cause. Ken Livingstone, mayor of London, later credited Friedman with inspiring London’s pathbreaking congestion charge.
