Dr. Tardiff received a B.S. with honors in Mathematics
from the California Institute of Technology in Pasadena and a Ph.D. degree in
Social Science from the University of California, Irvine, under a National
Science Foundation Pre-doctoral Fellowship and an NSF Grant for Improving
Dissertation Research in the Social Sciences.
Dr. Tardiff joined the faculties of the Department of
Civil Engineering and the Division of Environmental Studies at the University
of California, Davis. He taught
undergraduate and graduate level courses in transportation and environmental
policy analysis. His research included
applications of econometric models of consumer choice to transportation
planning problems. Dr. Tardiff's
research was funded by the National Science Foundation, the Institute of
Transportation Studies and the California Department of Transportation.
Prior to joining NERA, Dr. Tardiff's work included
transportation, energy, public utility and telephone industry projects for the
U.S. Departments of Transportation and Energy, the California Energy
Commission, and several telephone and electric utilities.
Since joining NERA, he has evaluated pricing policies for
increasingly competitive telecommunications markets, including appropriate
mechanisms for pricing access services to competitors; studied actual and
potential competition for services provided by telephone operating companies;
analyzed the demand and revenue impacts of new telephone rate structures;
developed and evaluated damage studies used in major telecommunications
antitrust actions; analyzed the market potential for cellular radio; evaluated
the investment and marketing programs of telephone companies; and developed a
demand model for analyzing the market potential for alternative employee health
care plans, including health maintenance organizations.
Dr. Tardiff has published extensively in the
transportation literature. He has
presented and published papers on the telecommunications industry. These papers address the issues of pricing
and costing policies for emerging competition in telecommunications markets;
evaluating and forecasting the impacts of telephone rate plans such as local
measured service; analyzing the markets for new telecommunications products and
services; and local competition and the bypass issue.
