TLDR
In this paper, the authors consider the null hypothesis that a time series has a unit root with possibly nonzero drift against the alternative that the process is "trend-stationary" and show how standard tests of the unit root hypothesis against trend stationary alternatives cannot reject the unit-root hypothesis if the true data generating mechanism is that of stationary fluctuations around a trend function which contains a one-time break.
Abstract
We consider the null hypothesis that a time series has a unit root with possibly nonzero drift against the alternative that the process is «trend-stationary». The interest is that we allow under both the null and alternative hypotheses for the presence for a one-time change in the level or in the slope of the trend function. We show how standard tests of the unit root hypothesis against trend stationary alternatives cannot reject the unit root hypothesis if the true data generating mechanism is that of stationary fluctuations around a trend function which contains a one-time break

Product Aggregation, Market Integration, and Relationships between Prices: An Application to World Salmon Markets

TL;DR: In this article, the Law of One Price holds for an international market with five salmon species, which has significant implications for the world salmon market regarding both product aggregation in demand analyses and international trade policy.

Drawing Inferences from Statistics Based on Multi-Year Asset Returns

TL;DR: In this paper, an alternative asymptotic distribution theory for statistics involving multi-year returns has been proposed, which provides substantially better approximations to the relevant finite-sample distributions and leads to empirical inferences much less at odds with the hypothesis of no mean reversion.

Gls-based unit root tests with multiple structural breaks under both the null and the alternative hypotheses

TL;DR: Kim and Perron as discussed by the authors extended their work in several directions: (1) they allow for an arbitrary number of changes in both the level and slope of the trend function; (2) they adopt the quasi-generalized least squares detrending method advocated by Elliott, Rothenberg, and Stock (1996, Econometrica 64, 813-836); and (3) they consider a variety of tests, in particular the class of M-tests introduced in Stock (1999, Cointegration, Causality, and Forecasting: A

Energy Consumption, Financial Development and Economic Growth in India: New Evidence from a Nonlinear and Asymmetric Analysis

TL;DR: In this article, the authors investigated the asymmetric relationship between energy consumption and economic growth by incorporating financial development, capital and labour into a production function covering the Indian economy from 1960Q1-2015Q4.

Distribution of the Estimators for Autoregressive Time Series with a Unit Root

TL;DR: In this article, the limit distributions of the estimator of p and of the regression t test are derived under the assumption that p = ± 1, where p is a fixed constant and t is a sequence of independent normal random variables.

Testing for a Unit Root in Time Series Regression

TL;DR: In this article, the authors proposed new tests for detecting the presence of a unit root in quite general time series models, which accommodate models with a fitted drift and a time trend so that they may be used to discriminate between unit root nonstationarity and stationarity about a deterministic trend.

Convergence of Probability Measures

TL;DR: Weak Convergence in Metric Spaces as discussed by the authors is one of the most common modes of convergence in metric spaces, and it can be seen as a form of weak convergence in metric space.
