We exploit natural experiment conditions in Switzerland to analyze the impact of three different "bonus"/ malus" annual registration fee schemes implemented at the cantonal level.
In recent years, upon increasingly exploiting natural sandstone, the natural ecology has been damaged severely.
To estimate the effects of large cuts in pensions on the age of first benefit receipt, we exploit two natural experiments in which such cuts affect a group of repatriated ethnic German workers.
NASA satellites, he said, could exploit those natural experiments by collecting radiation or particles, insuring that physicists would no longer be "victims of the last [terrestrial] machine you built".
We further identify this effect by exploiting the natural experiment arising from troop withdrawals in Iraq and Afghanistan as an exogenous shock to local, occupation specific labor supply.
It is designed to achieve causal inference by exploiting the natural experiment created by the introduction of gas development, at standard levels of statistical significance, no different than any other non-randomized double blind control trial.
We measure the impact of universal prekindergarten for four-year-olds by exploiting a natural experiment in which the Australian state of Queensland eliminated its public prekindergarten program in 2007.

The distinction between natural and synthetic materials is complicated by the fact that since the beginning of the 19th century, the manufacturers experimented with new ways to exploit natural dyes as pigments, by precipitating the natural extracts as salts in alkaline conditions.
