Estimation of Economics Damages

Estimated revenues and profits for the Kansas City Franchise of Robert Half for several new lines of business that they were not allowed to offer. Matched occupations to each line of business and used employment statistics for those occupations to model revenues and expenses in other cities. Then used the model to estimate past and future revenues and expenses for KC. Also estimated revenues for another city in their franchise area that would have been profitable had they been allowed to carry the new lines.

UtiliCorp v. GE. After a power plant explosion, UCU claimed that it had to buy expensive power on the spot market. Analyzed power contracts and trading data to determine whether these purchases were used to supply local customers or resold for a profit.

MDL 551 and Chemical Bank v. Benton PUD, et al. Managed a team of academic economists in a multi-billion dollar securities fraud case charging inadequate disclosure in bond prospectuses. Worked with top law firms from around the county to establish theories of liability, review and organize documents, interview potential experts, conduct statistical analyses, review pleadings, assist in taking depositions, review testimony, and coordinate activities with other groups of experts. Written commendation was obtained from counsel.

For use in personal injury litigation, developed models to estimate the probability of vehicle accidents at railroad crossings given traffic volumes and crossing characteristics. Logit models (logistic regressions) were developed for accidents, injuries and fatalities using the National Highway-Rail Crossing Inventory and Highway-Rail Grade Crossing Accident/Incident databases obtained from the U.S. Federal Railroad Administration.

For use in personal injury litigation, developed models to forecast probabilities of full time employment for individuals who abuse drugs or alcohol given monthly usage and demographic characteristics. A logit model was developed using responses to the 1999 National Household Survey on Drug Abuse.

For use in personal injury litigation, developed models to forecast probabilities of full time employment for individuals with spinal cord injuries given degree of injury and demographic characteristics. A logit model was developed using the National Spinal Cord Injury Database.

Happy Tours v. NYEX. Estimated lost business revenues in a civil suit and testified on the results.

Developed a model to analyze portfolio risk in venture capital funds for a client in a civil suit.

Estimated lost profits to a distributor of building materials when his contract with the manufacturer was wrongfully terminated.

Bluebonnet Savings Bank v Federal Deposit Insurance Corp., Case No. CA3-91-1066-X, U.S. District Court, Northern District of Texas Dallas Division. Used cluster analysis to associate an S&L to similar institutions so that market value could be determined. Also modeled market to book ratios for a group of publicly traded S&Ls.

Cape Mobile Home Mart v. Security Pacific Housing (Franklin County, MO). Critiqued analysis of lost sales revenues and developed an alternative analysis.

FoxMeyer v. Smith Drug Company (Circuit Court of Jackson County MO). Estimated lost revenues. 1995.

Mt. Carmel Medical Center. Critiqued a audit conducted by Kansas on a sample of Medicaid claims submitted by the Center. Determined that inappropriate sampling procedures were used in the audit. Identified which procedures should have been used. Performed a similar analysis for Oak Hill Hospital.

Analysis and Testimony for Regulatory Filings

For Florida Power and Light, analyzed survey responses to prepare a graphics based report that summarized appliance stocks and household characteristics. Used these results to construct input files for REEPS, an end-use forecasting model.

Developed conditional demand models to determine appliance specific energy consumption rates and load profiles for households and commercial buildings. Studies were conducted for PG&E, FPL, SDG&E, BC Hydro and EPRI. Taught utility staff how to conduct conditional demand analysis.

To support Florida Power & Light’s DSM planning efforts, specified and estimated penetration models for 12 energy conservation measures. The probabilities for the adoption of each measure were estimated using a Logit specification based on household income, demographic characteristics, weather, and appliance ownership and fuel types.

Built econometric models to forecast natural gas and electric sales and peak demands for many utilities. In several projects, developed simple models for inclusion in computer spreadsheets, and in many other projects, simulated loads based on long historical weather histories and economic scenarios to develop probabilistic confidence bands.

Adapted end-use forecasting models to utility service areas, incorporating data on appliance saturations and energy consumption rates, demographics, and economics.

For Wisconsin Electric, conducted a billing analysis to measure savings from the Appliance Turn-In Program for refrigerators, freezers and room air conditioners. Based on a customer survey, measured free ridership rates and modeled the long-run impacts of the program on appliance penetrations.

For Burlington Electric in Vermont, conducted a billing analysis to measure savings for the Neighbor $ave and Smart Light programs. Applied advanced econometric techniques to measure significant levels of savings.

For the South Carolina Public Service Authority, measured net energy savings from the Good Cents conservation program available to both new construction and retrofitted homes. Modeled monthly billed consumption, accounting for appliance stocks, demographic characteristics and Good Cents certification.

For EPRI, developed the Commercial Sector Demand Side Management Impact Assessment, computer software and report.

Strategic Planning

Cooperated with supply planning engineers to evaluate the economic feasibility of expanding a transmission and distribution system. Built a model to simulate peak energy demand using 108 years of weather data and assisted supply planners in using the results of this model to simulate outage costs with a system planning model.

For a large municipal utility, managed a gas supply options study to 1) forecast daily loads under various economic and weather scenarios, 2) forecast gas prices and evaluate pipeline companies, and 3) develop a model to evaluate option portfolios which included LNG, under ground storage, long-term pipeline contracts, and gas purchased on spot markets. Made specific recommendations.
