There is no available Prais-Winsten algorithm for regression with AR(2) or higher order errors, and the one with AR(1) errors is not fully justified or is implemented incorrectly (thus being inefficient). This paper addresses both issues, providing an accurate, computationally fast, and...

In this paper we introduce a new test of the null hypothesis of nocointegration between a pair of time series. For a very simple generating model, ourtest compares favourably with the Engle-Granger/Dickey-Fuller test and the Johansentrace test. Indeed, shortcomings of the former motivated the...

Stationarity of hedge ratios can be viewed as a first step for portfolio hedging since it represents that the sensitivity of spot and futures returns follow a process whose main characteristics do not depend on time. However, we provide evidence that the hedge ratios of the main European stock...
