The literature shows that for most UK industries privatization might be necessary but is not sufficient to produce economic benefits. Often prior changes in management or later changes in market structure and regulation have larger impacts than privatization itself. We ask what changes around...

The paper shows how commodity taxes can provide insurance to consumers when the producer price is volatile. Specific and ad valorem taxes have differing roles. The optimal specific tax is positive when demand has some elasticity. The optimal ad valorem rate is zero when demand is unit-elastic,...
