Efficient Tests for an Autoregressive Unit Root [PDF]

open access: yesEconometrica, 1996
Summary: The asymptotic power envelope is derived for point-optimal tests of a unit root in the autoregressive representation of a Gaussian time series under various trend specifications. We propose a family of tests whose asymptotic power functions are tangent to the power envelope at one point and are never far below the envelope. When the series has

Commodity Prices and Unit Root Tests [PDF]

open access: yesAmerican Journal of Agricultural Economics, 2007
AbstractPrice theory suggests that commodity prices should be stationary series. Yet, tests for unit roots rather frequently imply that these prices are not stationary. This seeming inconsistency is investigated by applying alternative specifications of unit root tests to prices of corn, soybeans, barrows and gilts, and milk.
