Agencies tend to manage what can be readily measured, but with a large toolbox of analytical and data collection techniques and some creativity, so much more is possible! I leverage a background in economic and statistics with the use of survey data collection approaches to generate valid and reliable data to enhance decision-making. Each project I work on, I strive to combine rigorous analysis with effective communication.


Dr. Lou Nadeau, an ERG senior economist and vice president, is an expert in econometrics, economic valuation, statistical analysis, survey design and implementation, and program evaluation. During his 30+ year career at ERG, he has applied his expertise to provide clients with actionable data to inform decisions in areas ranging from program development to policies concerning ecosystem goods and services. He has designed and implemented more than 50 large- and small-scale surveys over his career ranging from online panels to in-person data collection efforts. Government agencies such as the National Oceanic and Atmospheric Administration, U.S. Food and Drug Administration, U.S. Department of Labor, U.S. Environmental Protection Agency, and Commission for Environmental Cooperation have used Lou’s services to learn where their programs are making impacts, discover ways to improve program effectiveness, and provide a data-based foundation for enhanced management decision-making. Lou is hands-on in the projects he manages, leading interviews and conducting statistical analyses. He is an expert at designing complex surveys that test out new ideas to inform decisions and in developing sampling plans to ensure survey data will provide valid and reliable information for decision-making.
