Empirical evidence has emerged of the possibility of fractional cointegration such that the gap, β, between the integration order δ of observable time series and the integration order γ of cointegrating errors is less than 0.5. This includes circumstances when observables are stationary or...

We develop a sequence of tests for specifying the cointegrating rank of, possibly fractional, multiple time series. Memory parameters of observables are treated as unknown, as are those of possible cointegrating errors. The individual test statistics have standard null asymptotics and are...

Nonparametric regression with spatial, or spatio-temporal, data is considered. The conditional mean of a dependent variable, given explanatory ones, is a nonparametric function, while the conditional covariance reflects spatial correlation. Conditional heteroscedasticity is also allowed, as well...

This teaching note reports and evaluates an initiative to enhance first-year accounting students' written communication skills in a large class setting. The procedures adopted are outlined and empirical evidence of the effectiveness of these procedures in enhancing writing skills is provided....

This authoritative and comprehensive Handbook showcases the nature and benefits of the new wave in entrepreneurship education emerging as a result of revised academic programmes developed to reflect new forms of entrepreneurship.

Nonlinear functions of multivariate financial time series can exhibit long memory and fractional cointegration. However, tools for analysing these phenomena have principally been justified under assumptions that are invalid in this setting. Determination of asymptotic theory under more plausible...
