This article proposes contemporary best-practice recommendations for stated preference (SP) studies used to inform decision-making, grounded in the accumulated body of peer-reviewed literature. The recommendations cover both use and non-use values, including contingent valuation and discrete choice experiments (CEs). The focus is on applications to public goods in environmental and human health contexts, but the recommendations are also applicable to other areas. The article aims to raise the quality of SP studies and promote research that enhances their practice worldwide. It addresses survey development and implementation, value elicitation, data analysis, validity assessment, and study reporting. Key recommendations include clear and credible scenario descriptions, thorough pretesting, and a balanced approach between CV and CEs based on respondent perceptions and study objectives. The goal is to provide a comprehensive set of guidelines that are more relevant and up-to-date than those from the original National Oceanic and Atmospheric Administration (NOAA) Blue Ribbon Panel on contingent valuation.This article proposes contemporary best-practice recommendations for stated preference (SP) studies used to inform decision-making, grounded in the accumulated body of peer-reviewed literature.
