The Theory of Purchasing Power Parity in MENA Countries: The Quantile Unit Root Test [PDF]
This paper examines the theory of purchasing power parity aboutthe exchange rate of the dollar with local currencies in MENAcountries - the Middle East and North Africa - using a unit root testestablished on the quantile auto regressive model during the ...

Efficient Tests for an Autoregressive Unit Root [PDF]
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

Bayesian Unit Root Test with Outliers Observations: The Case of Daily Returns of 50 Active in Tehran Stock Exchange Companies [PDF]
The main drawback of classical ADF and PP tests is the low power of test in small samples and their asymptotic distribution discontinuous. In contrast, many prominent scholars support the Bayesian unit root tests. In the present study, Bayesian unit root

Commodity Prices and Unit Root Tests [PDF]
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.
