Dr. Wonjun Chang is a Senior Consultant in NERA’s Global Energy, Environment, Communications & Infrastructure (EECI) Practice. Dr. Chang’s work specializes in computational methods with applications in energy systems modeling and uncertainty analysis. He has provided business advisory services using stochastic optimization models that simulate value stacking strategies of energy storage resources in wholesale electricity markets. He has also authored numerous policy reports using computable general equilibrium (CGE) models of the global economy that provide economy-wide assessments of shocks to the energy sector. Dr. Chang’s recent modeling work assesses the economic value of perfect information on high-impact, low-probability thresholds, such as climate tipping points and environmental thresholds.

Prior to joining NERA, Dr. Chang was an economist at Pacific Northwest National Laboratory conducting macroeconomic modeling to aid the US Energy Information Administration’s International Energy Outlook. Dr. Chang has previously given workshops for the European Union, modeling large-scale energy systems, and the Korean Emissions Trading System. As an expert in stochastic analysis, he has also advised research on stochastic climate-economy models at the Yale School of Forestry and Environmental Studies. His doctoral thesis on stochastic dynamic programming is currently used as a solution method in the General Algebraic Modeling System (GAMS) modeling language.

Dr. Chang has written numerous academic papers and reports in the field of climate, environmental, energy, and computational economics, including publications in Computational Economics and Climate Change Economics.
