ceteris paribus: a most dangerous economists' tool

Whilst ceteris paribus helps economists indulge in their propositions, the naked reality has been such that nothing is ever in that state in life. Those employing the concept while trying to solve practical problems are condemned to be erroneous--the more serious the problems, the graver the mistakes. The announcement in Kompas today by head of the statistics bureau about March inflation rate has proved that the mainstream economists were wrong in estimating the effect of the latest fuel price hike on the inflation rate. The invisible poor are already starting to suffer more "beautifully"; let everyone be reminded once again. That ceteris paribus doesn't live here. It never did and never will.
