Objectives: ## The general objectives of this project are to determine what allocation of decision-making authority maximizes for social welfare in a problem of providing local public goods; and ## Collect original data generated by an organizational experiment to test and revise the theory and distill policy implications. In the empirical context, the organizational change, it was taken under an observation that due to a natural disaster, the natural occurrence of high concentrations of arsenic increased in groundwater of Bangladesh. Main Objectives of the research: # Theory: Determine what allocation of decision-making authority maximizes social welfare in a problem of providing a local public good. It was focused on: * Compare the outcomes when a central organization such as a NGO, government or private firm, makes all decisions and the community, which will be using public goods, makes all decisions in a dynamic model of interaction between individual agents. * Determine what allocation of decision-making authority maximizes for social welfare. * Determine how the welfare-maximizing allocation of decision-making authority and outcomes in the case of individual and average attributes of social networks. # Empirical: Collect original data generated by an organizational experiment to test and revise the theory and distill policy implications. It will: * Conduct an organizational experiment. * Determine which intervention yields the best average outcome. * Use the control group to study communities in which collective action occurs in the absence of any intervention
