Charles Moul is Assistant Professor of Economics at Washington University in St Louis. His work documenting evidence of how movie quality improved as studios gained experience with synchronous-sound recording (i.e. 'talkie') technology has appeared in the Journal of Industrial Economics. Professor Moul's ongoing research addresses whether economics is a valid and useful tool to analyze as volatile a process as weekly movie demand, how demand for a movie saturates as the pool of potential consumers views it, and the value of advertising to society. In April 2003, he organized and hosted 'Entertainment Economics: The Movie Industry', a conference bringing together leading authorities in digital production, copyright law, marketing, economics, accounting, and regulation.
