Addressed issues such as relevant market definition for gas line repair services, whether the company possessed market power, and whether certain company activities should be considered essential inputs and subject to sharing with competitors.
  • Expert Testimony on Total Factor Productivity and Performance-Based Ratemaking in Electricity: Testified on behalf of the Public Utilities Commission of Alberta, Canada on total factor productivity estimates for U.S. electricity distribution companies for use in arriving at an X-factor in a price cap proceeding plan for the electricity distribution and transmission operators in Alberta.

Estimated econometric price models for mobile and fixed-line services using a panel of 20 similar countries, and used model to compare predicted and actual prices.
  • Electricity Market Restructuring and Market Power Assessment: On behalf of the Mexican Energy Secretary, led a team of economists in the liberalization and market design of the Mexican wholesale electricity market and addressed issues such as identification of relevant markets, horizontal generation divestiture, vesting contracts, and financial transmission rights.
  • Electricity Demand Modeling and Forecasts: On behalf of the Mexican gas regulator, developed econometric electricity demand model used for forecasting electricity and natural gas generation input demand.
  • Broadband Demand Modeling and Forecasts: On behalf of the Mexican telecommunications regulator, developed econometric broadband demand model used for determining economic factors driving demand and for forecasting broadband penetration.
  • Competitive Analysis of Retail and Wholesale Petroleum Asset Sales in Central America: On behalf of a major international petroleum company, performed merger analysis examining the competitive effects of a transaction on retail gas station and wholesale petroleum assets.
