Volume 1, Issue 1, Posted Online: May 22, 2019

Abstract: Effective assessment of student learning is challenging for several reasons. Not only do learning assessments usually crowd out instructional time, but it can be difficult to assess higher-order cognitive aspects of student learning. In this commentary, I present a method for assessing student learning through the use of a digital grading platform that addresses both of these issues. I discuss a case study where this method was implemented and utilized to inform course design, and I argue that digital grading platforms expand instructors’ options for student learning assessments.

Abstract: A strong understanding of calculating and interpreting percentage changes and growth rates is critically important for economists. This is because many fundamental concepts such as the time value of money, and many commonly reported economic measures, such as the rate of return on assets, price inflation, and measures of economic growth, require a firm understanding of percentage changes. This paper presents a brief primer on calculating and interpreting percentage changes and growth rates. The purpose is to illuminate these measures, facilitate their interpretation, and clarify their usage for economic analysis.

Enhancing the Teaching of Product Substitutes/Complements: A Pedagogical Note on Diversion Ratios

Abstract
Application of diversion ratios in demand analysis has received little attention. Even microeconomic textbooks typically do not address this topic. The literature review presented here shows use of diversion ratios, along with cross-price elasticities, to study the price effects associated with mergers and acquisitions, a practice recommended to measure product substitutability/complementarity. With the aim of expanding experiential learning in the fields of applied economics, agricultural economics, and agribusiness, this article demonstrates how diversion ratios can be calculated from any uncompensated own-price and cross-price elasticity matrix derived from the analysis of demand systems, and it discusses the teaching of this concept in the classroom. 

Keywords: Diversion ratios, demand systems, cross-price elasticities, identification of next-best substitutes

Abstract: This case explores efforts to improve occupational health and safety at RRV Cooperative, a fictional agricultural cooperative located in the upper Midwest. Students are introduced to the operations of farm supply and grain marketing cooperatives and to fundamental concepts in occupational health and safety. Students are asked to analyze data and consider the challenges in changing personal and group habits. Background information presented in this case offers additional teaching opportunities regarding trends in the farm supply and grain marketing industry and U.S. production agriculture.

Teaching and Education Commentaries

Let's take a moment to celebrate great teaching!

Abstract: This commentary uses the history of the teaching awards program of the Agricultural and Applied Economics Association (AAEA) to examine the AAEA’s commitment to the teaching mission of universities with undergraduate programs in agricultural and applied economics. Through an archival review of AAEA historical documents, it describes an evolving commitment. It also identifies, from the author’s personal perspective, several awards program benefits and raises several concerns about potential biases in the selection of awardees. The commentary is, above all, a tribute to teaching and to AAEA teaching award recipients—past and future.

Moneyball in the Academy: Whiffing on the Quality of Education?

Paul N. Wilson

Volume 1, Issue 1, Posted online: May 30, 2019

Abstract: In recent years, corporate-like resource management tools have become commonplace on many university campuses with the goal of improving economic efficiency at the organizational level. Administrative initiatives that calculate faculty and department value with a limited number of metrics jeopardize the relational and hence the learning environment of higher education, particularly at the undergraduate level. Mutual faculty-student engagement remains a critical component of a quality education.
