We examine the properties of several residual-based cointegration tests when long run parameters are subject to multiple shifts driven by an unobservable Markov process. Unlike earlier work, which considered one-o¤ deterministic breaks, our approach has the advantage of allowing for an unspeci…ed number of stochastic breaks. We illustrate this issue by exploring the possibility of Markov switch...

This paper examines the validity of purchasing power parity (PPP) using CPI and Big Mac prices. The benchmark model, i.e., the OLS method, which does not take nonstationarity into account, rejects the hypothesis of PPP regardless of prices used. We next use the panel cointegration method to consider the nonstationary nature of variables. Estimated results for CPI are mixed. The PPP is rejected ...

Applying Johansen cointegration test to U.S. annual data constructed from the EU KLEMS database, the paper documents that the productivities of consumption-goods and equipmentgoods sector are cointegrated. It confirms further, using the non-linear cointegration test framework developed by Kapetanios et al. (2006), that the cointegrating relation is non-linear. The cointegration of sectoral prod...

We study the development of conjunctive keyword searchable scheme which enables one to search encrypted documents by using more than one keyword. The notion of conjunctive keyword searching was presented by Golle et al. in 2004. However, their security model was constructed in a symmetric-key setting which is not applicable for the overall applications in the reality. So Park et al. extended Go...

In this paper we present several proofs on the extension of M. Riesz fractional integration and di¤erentiation to the contexts of spaces of homogeneous type and measure metric spaces with non-doubling measures. 1. Introduction, some de…nitions, and a basic lemma Professor M. Ash asked me to write a survey article on some of the results that Stephen Vági and I obtained in the nineties on fractio...

Cointegration has different theoretical implications for forecasting. Several empirical studies have compared the out of sample forecasting performance of cointegrted VECMs against unrestricted VARs in levels and in differences. The results of these studies have been generally mixed and inconclusive. This paper provides a comprehensive review over the subject, and also examines the effects...

This paper sought to investigate the cointegration relationship between asymmetric information and equity returns. Previous literature has shown influences Assets returns but it is less known whether there exists a long run these variables. In this regard stationarity tests Johansen test were employed ascertain two Data composed of monthly transaction on 20 equities used in formulation NSE shar...
