Existence of a cointegration relationship between two time series in the time domain imposes restrictions on the series zero-frequency behaviour in terms of their squared coherence, phase, and gain, in the frequency domain. I derive these restrictions by studying cross-spectral properties of a...

This paper considers the dynamics of spot and futures prices in the presence of arbitrage. A partially linear error correction model is proposed where the adjustment coefficient is allowed to depend non-linearly on the lagged price difference. The model is estimated using data on the DAX index...

This paper provides an extensive Monte-Carlo comparison of severalcontemporary cointegration tests. Apart from the familiar Gaussian basedtests of Johansen, we also consider tests based on non-Gaussianquasi-likelihoods. Moreover, we compare the performance of these parametrictests with tests...

Modeling fractional cointegration relationships has become a major topic in applied time series analysis as it steps back from the traditional rigid I(1)/I(0) methodology. Hence, the number of proposed tests and approaches has grown over the last decade. The aim of this paper is to study the...

The paper aims to study the market efficiency, unbiasedness and direction of causality among four agricultural commodities futures contracts traded at National Commodity & Derivatives Exchange Ltd. (NCDEX). The study has tested the efficiency and unbiasedness using Johansen's Cointegration...

The paper aims to study the market efficiency, unbiasedness among Guar gum futures contracts traded at National Commodity & Derivatives Exchange Ltd (NCDEX). The study has tested the market efficiency and unbiasedness with different maturities using cointegration analysis, and short-term market...

This paper studies nonlinear cointegration models in which the structural coefficients may evolve smoothly over time. These time-varying coefficient functions are well-suited to many practical applications and can be estimated conveniently by nonparametric kernel methods. It is shown that the...
