A COINTEGRATION ANALYSIS FOR THE VALIDITY OF PURCHASING POWER PARITY: EVIDENCE FROM MIDDLE EAST COUNTRIES

Purchasing Power Parity Hypothesis In OIC Countries: Evidence From Panel Unit Root Tests With Heterogeneous Structural Breaks

Symmetry, Proportionality and the Purchasing Power Parity: Evidence from Panel Cointegration Tests

The objective of this paper is to examine the long-run Purchasing Power Parity hypothesis in a dynamic panel of twenty OECD countries, using recently developed heterogeneous panel cointegration tests that have not been previously applied to PPP. Another contribution is that we investigate the symmetry and proportionality conditions in PPP using likelihood-based inference as suggested by Johanse...

Nonlinear cointegration: Theory and Application to Purchasing Power Parity

In this paper, we study a smooth-transition type of nonlinear cointegration among a dynamic system, in which the proposed definition nests Engle and Granger (1987)’s linear cointegration. Based on the Smooth Transition Autoregressive (STAR) models, a triangular representation for the nonlinearly cointegrated system is introduced. Furthermore, two tests for nonlinear cointegration are derived in...

Testing for linear cointegration against nonlinear cointegration: Theory and application to Purchasing power parity

In this thesis, we study a smooth-transition type of nonlinear cointegration among a dynamic system. Base on the Logistic Smooth Transition Autoregressive (LSTAR) models, the definition of cointegration which is extended form Engle and Granger (1987)’s definition of linear cointegration is introduced. Then statistical test for linear cointegration against nonlinear cointegration is derived. The...

Purchasing Power Parity: Evidence from a New Test

Most economists intuitively consider purchasing power parity (PPP) to be true. Nevertheless, quite surprisingly, the empirical literature is not very supportive for PPP. In this paper, however, we …nd evidence in favor of PPP using a new test. The test is embedded in a Markov regime-switching model for the exchange rate, because earlier papers have shown that this model describes the data bette...
