following the classical approach based on I(0) stationarity or I(1) cointegrating relationships, we use fractional integration/cointegration … three variables are I(1). But we only find cointegration in the presence of autocorrelated disturbances, which means that … opposed to classical cointegration, which implies long memory and slow reversion to equilibrium. This suggests that an …

This article is concerned with the dynamic behaviour of UK unemployment. However, instead of using traditional approaches based on I(0) stationary or I(1) (integrated and/or cointegrated) models, we use the fractional integration framework. In doing so, we allow for a more careful study of the...

In this paper a Canonical Correlation Analysis (CCA) is used to test the hypothesis r = r0 against the alternative r … to construct a confidence set for the cointegration rank. As the latter test, our tests are based on the eigenvalues of a … CCA between differences and lagged levels of a time series vector. The resulting test statistics can easily be adjusted …

In mathematical finance diffusion models are widely used and a variety of different parametric models for the drift and diffusion coefficient coexist in the literature. Since derivative prices depend on the particular parametric model of the diffusion coefficient function of the underlying, a...

A procedure for testing equality across nonparametric regressions is proposed. The procedure allows for any dimension of the explanatory variables and for any number of subsamples. We consider the case of random explanatory variables and allow the designs of the regressors and the number of...

A procedure for testing the signicance of a subset of explanatory variables in a nonparametric regression is proposed. Our test statistic uses the kernel method. Under the null hypothesis of no effect of the variables under test, we show that our test statistic has a nhp2/2 standard normal...

The efficient market hypothesis implies that asset prices cannot be cointegrated. On the other hand, arbitrage processes prevent prices of fundamentally related assets from drifting far away. An attractive model that reconciles these two conflicting facts is the nonlinear error correction...

We propose in this article the use of a particular version of the tests of Robinson (1994) for testing seasonally fractionally integrated processes. The tests have standard null and local limit distributions and allow us to test unit and fractional seasonal roots even with different amplitudes...
