David Fitoussi is an authority on the economics and investments of information technology in businesses.

His principal research area is on IT’s economic impact on the organization of firms. His research on the relationship between IT and the location of workers helped quantify the relative importance of various spatial and organizational characteristics in work location, and their sensitivity to IT investments. He has also done innovative research on the design of rules for multi-agent systems in artificial intelligence.
 
With professors at MIT and the Wharton School, he has studied the characteristics and magnitude of intangible costs and benefits of IT investments. They found that although these costs amount to a majority of IT investment expenses, they are usually written off as expenses in corporate accounting systems and ultimately in government accounts of IT. This potentially leads to major biases in studies of how much IT affects firms and the U.S. economy.

Professor Fitoussi is an affiliated faculty member with CRITO, the Center for Research on Information Technology and Organizations at UC Irvine.
