We show that the use of the real effective exchange rate to test for purchasing power parity, as in Astorga (2012) and other studies, introduces a bias against finding evidence of PPP. The bias is illustrated using unit root tests applied to bilateral real rates.

Results from unit root tests applied to the bilateral China - US real exchange rate do not support purchasing power parity between the two countries. However, tests of the real equivalent exchange rate for the Chinese yuan versus a traded-weighted basket of currencies support purchasing power...

Purpose: The purpose of this paper is to explore the influence and advantages of leadership multiculturalism on global strategy development through cross-border mergers and acquisitions (CBA) and corporate social responsibility (CSR) from emerging market multinational companies (EMNCs)...

Im et al. (Unpublished working paper, <CitationRef CitationID="CR11">2008</CitationRef>) develop cointegration tests using stationary instrumental variables. Their tests avoid the need to simulate critical values for the cointegration estimations, especially problematic in the presence of a nuisance parameter. Likewise, bootstrapping...</citationref>

We test the purchasing power parity hypothesis for the Mexican peso/US dollar real exchange rate using monthly data for 1969–2010. Results suggest that the real exchange rate reverts to a changing mean. These mean shifts can be explained by liberalization policies implemented during the 1980s...

The long-run neutrality of money on real output is tested for Mexico using a model developed by Fisher and Seater. The empirical evidence supports the neutrality hypothesis. The results are robust for both M1 and M2 and an alternative model specification.

The Kapetanios, Shin, and Snell (KSS, 2003) test for a nonlinear unit root is used to study purchasing power parity using Taylor's extensive data set, d to include recent exchange rate and price level data. The results i) indicate that PPP holds with respect to the US dollar for most countries...

We make use of a data set that is both long span and high frequency to test for purchasing power parity while allowing for a structural shift in the volatility of the Mexico-US bilateral real exchange rate. The Kim, Leybourne and Newbold (2002) unit root test, robust to changes in the innovation...
