Spectral Based Testing of the Martingale Hypothesis
Durlauf, Steven N. - 1992
This paper proposes a method of testing whether a time series is a martingale. The procedure develops an asymptotic theory for the shape of the spectral distribution function of the first differences. Under the null hypothesis, this shape should be a diagonal line. several tests are developed...

A Specification Test for Speculative Bubbles
West, Kenneth D. - 1986
The set of parameters needed to calculate the expected present discounted value of a stream of dividends can be estimated in two ways. One may test for speculative bubbles, or fads, by testing whether the two estimates are the same. When the test is applied to some annual U.S. stock market data,...

Testing Models of Low-Frequency Variability
Mueller, Ulrich - 2006
We develop a framework to assess how successfully standard times eries models explain low-frequency variability of a data series. The low-frequency information is extracted by computing a finite number of weighted averages of the original data, where the weights are low-frequency trigonometric...

Are Macroeconomic Forecasts Informative? Cointegration Evidence from the ASA-NBER Surveys
Cheung, Yin-Wong - 1999
We examine the properties of the ASA-NBER forecasts for several US macroeconomic variables, specifically: (i) are the actual and forecast series integrated of the same order; (ii) are they cointegrated, and; (iii) is the cointegrating vector consistent with long run unitary elasticity of...

Non-Cointegration and Econometric Evaluation of Models of Regional Shift and Share
Brown, Scott J. - 1990
This paper tests for cointegration between regional output of an industry and national output of the same industry. An … equilibrium economic theory is presented to argue for the plausibility of cointegration, however, regional economic forecasting … using the shift and share framework often acts as if cointegration does not exist. Data analysis on broad industrial sectors …

A Simple MLE of Cointegrating Vectors in Higher Order Integrated Systems
Stock, James H. - 1989
An MLE of the unknown parameters of co integrating vectors is presented for systems in which some variables exhibit higher orders of integration, in which there might be deterministic components, and in which the co integrating vector itself might involve variables of differing orders of...

Low-Frequency Robust Cointegration Testing
Müller, Ulrich - 2009
Standard inference in cointegrating models is fragile because it relies on an assumption of an I(1) model for the common stochastic trends, which may not accurately describe the data's persistence. This paper discusses efficient low-frequency inference about cointegrating vectors that is robust...
