Objective: To propose an indicator of public value and evaluate its relationship with accountability. Theoretical framework: The study addresses public value and its plurality as well as accountability. Methodology: Descriptive-exploratory research was developed with the 608 Brazilian municipalities with over 50 thousand inhabitants as their unit of analysis and observation. The data were analyzed wing multivariate descriptive statistics and PLS method - structural equation modeling. Results: The constructs health, education, social inequality and poverty, work, housing conditions and basic sanitation, vulnerability and security, were explained by 92 variables that had significant and direct impacts to structure the public value indicator (p-value <= 0.05). In view of the structured model, the higher the items education, vulnerability, work, health and housing conditions and basic sanitation, the greater the generation of public value. A correlation can be observed between EBT_360, participatory budget and public value. Originality: Although some authors believe that public value does not involve appreciating choices made by public institutions, but rather the experience and perception of the service provided, the study sought to assess this generation of value from the delivery of goods and services by public managers, to the proposal an indicator of public value, a gap found in the literature. Theoretical and practical contributions: In view of the multiple understandings of what public value and accountability is, the research sought to define a concept regarding the delivery of goods and services by public managers and how they can better evaluate their management.
