Our team understands that new economic data and methods are always being developed, and that our economic analyses are importantly linked to other technical, legal, and institutional factors affecting water resources in the west. We continually innovate to improve our software, models, methods, and data by working with industry professionals, economists at leading academic institutions, research teams, and technical experts across other disciplines to publish new economic research and reports.
We publish some of our research in leading peer-reviewed professional journals and research reports. We also work with clients to prepare reports that can help policymakers understand the consequences of proposed regulations, actions, or other policy decisions.
