A note on testing for purchasing power parity∗
نویسنده
چکیده
We examine the asymptotic behavior of unit root tests against nonlinear alternatives of the exponential smooth transition type if the data is erroneously nonlinearly transformed. We show analytically and by a Monte Carlo study that the probability of rejecting the correct null of a random walk depends heavily on the type of data transformation. JEL-Numbers: C12, C22, F31

Some Evidence of Purchasing Power Parity
Empirical support for purchasing power parity is mixed with results dependent on the time frame and countries under examination, the methodology employed, attempts to control for aggregation bias in the data, and whether adjustments are made to account for productivity differences across nations. As a central component of macroeconomic thinking, purchasing power parity is battered and battle-wo...

Purchasing Power Parity Tests in Cointegrated Panels
This paper employs recently developed techniques for testing hypotheses in cointegrated panels to test the strong version of purchasing power parity for a panel of post Bretton Woods data. We compare results using fully modi ed and dynamic OLS approaches , and strongly reject the hypothesis . We also introduce a new between-dimensio n dynamic OLS estimator and nd that the between-dimensio n ...
متن کاملLow Power March Memory Test Algorithm for Static Random Access Memories (TECHNICAL NOTE)
Memories are most important building blocks in many digital systems. As the Integrated Circuits requirements are growing, the test circuitry must grow as well. There is a need for more efficient test techniques with low power and high speed. Many Memory Built in Self-Test techniques have been proposed to test memories. Compared with combinational and sequential circuits memory testing utilizes ...
