John D. Abell, Professor of Economics, holds the Carl Stern Chair of Economics at Randolph College in Lynchburg, Virginia. He received his Masters and Ph.D. degrees from the University of Kentucky (1983,1985).

His formal training was in the areas of macroeconomics, monetary economics, and finance. His early research employed traditional macroeconometric time series techniques to analyze the employment impacts of monetary and fiscal policies as they were distributed along racial and gender lines. His teaching and research have evolved over the years in the direction of food, sustainability, and local economics. This work has taken him from the central highlands of Guatemala to the streets of Lynchburg, Virginia.

In 2011, he offered a course on the “Economics of Food and Sustainability”. He and his students conducted research to determine the extent to which Lynchburg’s urban core constituted a food desert. They investigated convenience stores and nearby grocery stores to compare prices and food availability. They found prices averaging 90 percent more in the convenience stores and virtually no fresh food. Their findings were published in the Virginia Economic Journal in 2011.

Sabbatical research in spring semester 2014 on the topic of hunger and poverty in Lynchburg was documented in a video blog titled: “The hunger-poverty nexus. Food? What is its proper role? Case study of Lynchburg, Virginia.” The findings were also published in the Virginia Social Science Journal in 2015.

His current research connects the poverty in Lynchburg of the present, especially for blacks, with the racism of the past, in particular, the real estate redlining practices of the 1930s. Preliminary findings were published as an opinion piece in the News and Advance in April 2018.

Professor Abell has won the Gillie A. Larew Award (2005-06) given for outstanding teaching, and the Katherine Graves Davidson Award (2012-13) given to faculty who have brought distinction to the college.

Beyond Randolph’s “red brick walls,” Professor Abell has served on the board of directors of the Lynchburg Area Food Council (2012-14), serving one year as president and also serving on the board of Lynchburg Daily Bread (2016-19). He has assisted in the planning and construction of three community gardens: Randolph College’s own organic garden 2010), one in the Daniel’s Hill neighborhood (2013), and more recently at New Vistas School (2014).

B.S., Mississippi State University; M.S., Ph.D., University of Texas at Austin

Academics is my second career. As an undergraduate, I majored (at various times) in philosophy, chemistry, computer science, and chemical engineering. I finished with a degree in chemical engineering . . . and then promptly went to work as a petroleum engineer. I spent 12 years in the oil business, including 10 wonderful years in the Philippines, serving as an engineering and management consultant to petroleum companies.

The oil business was kind to me, but at the ripe old age of 35 I wanted to try something new. So I returned to graduate school at the University of Texas at Austin. I earned a Ph.D. in Economics . . . and then promptly began teaching business courses in MBA programs.

Today I pursue a career in academics, teaching and writing on topics in business and economics.  I particularly enjoy teaching Leadership, and teaching strategic thinking in the Business Capstone.

For fun, I travel abroad as often as I can. In 2009 I visited the Sekolah Bisnis dan Manajemen at the Institut Teknologi Bandung in Indonesia as a Fulbright Scholar, and more recently I taught at Franklin University of Switzerland.  I also enjoy being outdoors – hiking, sailing, and canoeing – and I dabble in residential architecture.

B.S., M.B.A., Bowling Green State University; Ph.D., Kent State University

I earned my BSBA and MBA degrees from Bowling Green State University in Bowling Green, Ohio and received a Ph.D. in Finance from Kent State University, also in Ohio.

I have professional experience in the areas of banking and corporate accounting. I have taught a wide range of courses in the past: finance, accounting, management, and economics. The students and their education are my main priorities. In keeping with this focus on student education, I enjoy conducting research that is applied and pedagogical in nature. I am particularly interested in topics that improve the classroom experience for the students and enhance my teaching effectiveness. Specific areas of research have included financial education/pedagogy, stakeholder theory, and firm value.

As for outside interests and activities, my wife, Denise, and I enjoy sports (biking, jogging, tennis, etc.), travel and relaxing (when possible).

I sum up my thoughts on business, and specifically finance, education as follows: I believe financial education is of value to students whether they pursue a career in the discipline or not. In particular, basic financial literacy is an important life skill. As a teacher, I would like students to gain an understanding of, and an appreciation for, finance and to have had a positive experience along the way.

Liz is an elected Social Sciences Councilor with the Council on Undergraduate Research and an experienced facilitator at CUR’s Social Science Institutes, helping teams of faculty and administrators from other institutions develop proposals for enhancing undergraduate research on their own campuses and speaking on curricular scaffolding for undergraduate research experiences. Within her own discipline, she is a former faculty advisor to the online student-refereed journal Illinois Wesleyan Undergraduate Economic Review (IWUER). She is the student research module coordinator for the National Science Foundation-funded Starting Point: Teaching and Learning Economics, a pedagogic portal project developed by economists in collaboration with the Science Education Resource Center of Carleton College (National Science Foundation Grant DUE0817382, $497,953, PIs: M. Maier, C. Manduca, K. McGoldrick, S. Simkins). She is the coauthor of The American Economist article “Creating Quality Undergraduate Research Programs in Economics: How, When, Where (and Why)” with Steve DeLoach and Mary Borg.

Liz advises independent undergraduate research projects in a number of her classrooms, but also engages in student/faculty community-based research collaborations with undergraduate students through paid summer research positions, independent studies, experiential learning opportunities, and her service learning public economics course. Currently, she and several students are working in service to the Tinbridge Hill neighborhood of Lynchburg, Virginia to assess the City Council-approved, neighborhood-owned Growing Tinbridge Hill Neighborhood Plan. Earlier student projects included collecting and analyzing data to help inform the goals of the Plan. A number of Liz’s students have presented their work to the local community and at regional conferences.
