"The European Conference of Ministers of Transport has released a report that analyzes the gap between fuel efficiency certification test ratings and the actual on-road fuel efficiency of automobiles. The report also examines technologies available that could reduce that gap and improve fuel...

There is an intense debate over whether fuel economy standards or fuel taxation is the more efficient policy instrument to raise fuel economy and reduce CO2 emissions of cars. The aim of this paper is to analyze the impact of standards and fuel prices on new car fuel economy with the aid of...
