Teaching and Research Interests
Dr. Dahlgran joined the faculty at The University of Arizona in 1985. His fields of major interest include econometric modeling of agricultural markets, the detection of structural change in these markets, and modeling interrelationships between cash and futures markets. He currently teaches courses on applied econometrics and the economics of futures markets and has received awards and recognition for his development and use of futures trading simulation software and multimedia-based presentation materials. He has taught economic forecasting short courses in Jamaica and Sudan. He is currently active in faculty governance at the university level.
Recent research has focused on measuring market interconnectedness for commodity and futures markets, methods of valuing contractually supplied inputs, the dynamics of futures-market price behavior, and evaluating the effectiveness of innovations used in teaching agricultural economics concepts.
