<title>Abstract</title> Unit-root testing strategies are unnecessarily complicated because they do not exploit prior knowledge of the growth status of the time series, they worry about unrealistic outcomes, and they double- or triple-test for unit roots.

Unit-root testing strategies are unnecessarily complicated because they do not exploit prior knowledge of the growth status of the time series, they worry about unrealistic outcomes, and they double- or triple-test for unit roots. The authors provide a testing strategy that cuts through these...

F tests which test jointly for a unit root and a zero intercept, and so compete against Dickey-Fuller t tests, are shown not to enhance power because they are invariant to the intercept value in the absence of a unit root. Monte Carlo results in the literature that indicate otherwise are shown...

Rodrigues and Tremayne (2004) interpret a problematic size result in a Monte Carlo study reported in Elder and Kennedy (2001) as arising from Elder and Kennedy's use of an inappropriate testing equation. In expositing their result, Rodrigues and Tremayne inadvertently lead readers to believe...

An extensive literature in education shows little relationship between teaching and research. Authors advance the notion that research enhances teaching, but they typically ignore the prospect of teaching enhancing research. We report the results of a survey of active researchers in economics...

Econometrics is an intellectual game played by rules based on the sampling distribution concept. Most students in econometrics classes are uncomfortable because they do not know these rules and so do not understand what is going on in econometrics. This article contains some explanations for...

The International Handbook on Teaching and Learning Economics provides a comprehensive resource for instructors and researchers in economics, both new and experienced. This wide-ranging collection is designed to enhance student learning by helping economic educators learn more about course...

Getting a “wrong†sign in empirical work is a common phenomenon. Remarkably, econometrics textbooks provide very little information to practitioners on how this problem can arise. The author exposits a long list of ways in which a wrong sign can occur and how it might be corrected.
