This study uses experimental methods to expiore whether incorporating reai options into net present value analysis can reduce escalation of commitment, or the tendency of decision makers to continue to commit resources to a project after receiving negative feedback. This reduction in escalation behavior should occur because the incorporation of real options offers the user greater cognitive accessibility to the possibility of project abandonment. Findings indicate that users of real options exhibit less escalation of commitment than do users of net present value analysis alone. The main result demonstrates that the use of real options in capital budgeting can affect the behavior and decisions of the user even in an experimental setting that controls for the informational advantage of using real options.

ChatGPT, a language-learning model chatbot, has garnered considerable attention for its ability to respond to users’ questions. Using data from 14 countries and 186 institutions, we compare ChatGPT and student performance for 28,085 questions from accounting assessments and textbook test banks. As of January 2023, ChatGPT provides correct answers for 56.5 percent of questions and partially correct answers for an additional 9.4 percent of questions. When considering point values for questions, students significantly outperform ChatGPT with a 76.7 percent average on assessments compared to 47.5 percent for ChatGPT if no partial credit is awarded and 56.5 percent if partial credit is awarded. Still, ChatGPT performs better than the student average for 15.8 percent of assessments when we include partial credit. We provide evidence of how ChatGPT performs on different question types, accounting topics, class levels, open/closed assessments, and test bank questions. We also discuss implications for accounting education and research.
