### About the Author

**Steven Tomlinson***Acton School of Business*

Steven Tomlinson teaches economics at the Acton School of Business in Austin, Texas. He graduated with highest honors from the University of Oklahoma and earned a Ph.D. in economics at Stanford University. Prof. Tomlinson's academic awards include the prestigious Texas Excellence Teaching Award given by the University of Texas Alumni Association and being named "Outstanding Core Faculty in the MBA Program" several times. He has developed several instructional guides and computerized educational programs for economics.

Prof. Tomlinson is also an accomplished theater artist, with more than half a dozen award-winning solo performances to his credit. One play, *Millennium Bug*, presents a world in which all human interactions are strictly governed by economic calculations. His most recent play, *American Fiesta*, won the American Theatre Critics Association's Osborn Award for Best New Play by an Emerging Playwright.

In his Thinkwell presentations, Prof. Tomlinson uses his academic expertise and his stage presence to dispel the notion of economics as "the dismal science."
