SERA  has conducted more than 330 energy and over 200 recycling/solid waste project assignments in the US and internationally, and has published extensively on our project research.  Skumatz Economic Research Associates (SERA) works in program design and evaluation in recycling / solid waste integrated materials management, energy efficiency, and sustainability Our staff includes economists and analysts with experience in evaluation, surveys and statistics, quantitative research, and policy analysis.  SERA has a reputation for quantitative, data-based research, and for developing creative approaches to find practical (and affordable) methods to quantify complex or hard-to-measure impacts. We have presented the results of our research in 150 papers in trade journals, refereed journals, and national and international conference proceedings.    

SERA has extensive experience in all phases of detailed survey design, statistics, and analysis for research and program evaluation purposes.  We have conducted statistical surveys using random or stratified random approaches to collect data from households, businesses, program agencies, and communities.  These surveys have been used to gather data from communities on solid waste programs and facilities, costs, and local information to analyze program options. SERA has conducted thousands of residential and commercial surveys to gather data on attitudes (including self-efficacy), behaviors, awareness, demographics, willingness-to-pay, program preferences, and other data for solid waste plans. We have conducted in-depth interview work with stakeholders and market actors on market issues, costs, capacity, program and policy strengths and weaknesses, and many other topics. Dr. Skumtaz has conducted and analyzed validation surveys, determining the accuracy and consistency of phone, on-site, and mail surveys for particular types of questions; developed complex sampling designs; and is highly skilled in identification and treatment of survey bias and weighting and imputation methods (including refereed journal paper on the topic). She has conducted statistical and modeling work for solid waste projects, using standard questions and data, as well as more complex analyses like regression analysis, principal components, logit, hazard analyses / measure lifetime analyses, logit modeling from card rankings, and other methods. 

In the Energy Field, SERA has conducted hundreds of survey projects for utilities, including surveys of the variety of relevant actors for process evaluation (participant, non-participants, builders / developers, and other stakeholders). We have conducted surveys for appliance saturation and end use surveys (commercial). We have extensive experience conducting, managing, and analyzing large survey projects for evaluation, measure retention/persistence, net-to-gross, NEBs, market share impacts, targeting / marketing and other applications.  SERA has expertise in survey issues including bias identification, imputation and bias reduction approaches, weighting, and other topics.
