🪚Public Policy Analysis Unit 7 – Evidence–Based Policy Making

What's Evidence-Based Policy Making?

• Approach to policy development that prioritizes using the best available research and data to inform decisions and achieve desired outcomes
• Involves systematically collecting, analyzing, and using high-quality evidence throughout the policy-making process
• Aims to reduce reliance on anecdotal evidence, intuition, or political ideology in favor of empirical data and rigorous analysis
• Focuses on identifying what works, for whom, under what circumstances, and at what cost
• Promotes transparency, accountability, and continuous improvement in policy design and implementation
  • Encourages policymakers to clearly articulate goals, assumptions, and evidence used
  • Facilitates monitoring and evaluation of policy impacts and unintended consequences
• Requires collaboration among researchers, policymakers, practitioners, and stakeholders to generate and apply relevant evidence
• Recognizes that evidence is just one input in the policy process, alongside values, resources, and political considerations

Key Players in Evidence-Based Policy

• Policymakers and elected officials who set priorities, allocate resources, and make decisions based on evidence
• Government agencies and departments responsible for implementing policies and collecting data on their effectiveness
• Research organizations and think tanks that conduct studies, analyze data, and provide policy recommendations
  • Examples include the RAND Corporation, Urban Institute, and Brookings Institution
• Academic institutions and individual researchers who generate new knowledge through scientific inquiry and evaluation
• Professional associations and advocacy groups that synthesize evidence and promote best practices in their fields (American Medical Association)
• Foundations and philanthropic organizations that fund research and support evidence-based initiatives (Bill and Melinda Gates Foundation)
• International organizations that set standards, share knowledge, and provide technical assistance (World Bank, OECD)
• Media outlets and journalists who communicate research findings and hold policymakers accountable for using evidence

Steps in the Evidence-Based Policy Process

• Define the policy problem or question, specifying the goals, target population, and desired outcomes
• Identify and assess existing evidence relevant to the policy issue, including research studies, program evaluations, and data from various sources
  • Conduct systematic reviews or meta-analyses to synthesize findings across multiple studies
  • Assess the quality, relevance, and applicability of evidence to the specific context
• Engage stakeholders and experts to gather input, build consensus, and ensure diverse perspectives are considered
• Develop policy options and assess their potential impacts, costs, and benefits using evidence-based models and tools
  • Use cost-benefit analysis or cost-effectiveness analysis to compare policy alternatives
  • Consider potential unintended consequences and distributional effects across different groups
• Select and implement the most promising policy option, allocating resources and establishing clear roles and responsibilities
• Monitor and evaluate the policy's implementation and outcomes using predefined indicators and data collection methods
  • Conduct process evaluations to assess fidelity to the policy design and identify implementation challenges
  • Conduct impact evaluations to measure the policy's effects on key outcomes and compare them to a counterfactual
• Refine and adapt the policy based on evaluation findings, changing circumstances, and new evidence that emerges over time

Types of Evidence Used

• Quantitative data from surveys, administrative records, or other sources that can be analyzed using statistical methods
  • Examples include census data, labor market statistics, and health care utilization rates
• Qualitative data from interviews, focus groups, or observations that provide rich, contextual information about people's experiences and perspectives
• Experimental studies that randomly assign participants to treatment and control groups to estimate the causal impact of an intervention (randomized controlled trials)
• Quasi-experimental studies that use statistical techniques to approximate experimental conditions when random assignment is not feasible (regression discontinuity designs)
• Observational studies that analyze associations between variables without manipulating them directly (cohort studies, case-control studies)
• Systematic reviews and meta-analyses that synthesize findings from multiple studies on a particular topic
• Economic analyses that assess the costs and benefits of different policy options (cost-benefit analysis, cost-effectiveness analysis)
• Simulation models that use mathematical equations to predict the likely outcomes of policy scenarios under different assumptions

Challenges and Limitations

• Limited availability or quality of relevant evidence for some policy issues, especially in emerging or rapidly changing fields
• Difficulty in generalizing findings from one context to another, given differences in populations, settings, and implementation factors
• Potential for bias or confounding in observational studies, which can lead to misleading conclusions about cause-and-effect relationships
• Time lags between the generation of evidence and its incorporation into policy decisions, which can delay the adoption of effective interventions
• Resistance to change among policymakers, practitioners, or the public, who may be skeptical of new evidence or attached to existing practices
• Competing priorities and political pressures that can override evidence-based considerations in the policy process
  • Policymakers may face short-term electoral incentives or interest group demands that conflict with long-term evidence
• Resource constraints that limit the capacity to collect, analyze, and use evidence in policy development and implementation
• Ethical concerns about the use of certain types of evidence, such as experiments that withhold potentially beneficial interventions from some participants

Real-World Examples

• The Oregon Health Insurance Experiment, which used a lottery to randomly assign Medicaid coverage and study its impacts on health outcomes and health care utilization
• The Nurse-Family Partnership program, which provides home visits by nurses to low-income, first-time mothers and has been shown to improve child health and development outcomes
• The Washington State Institute for Public Policy, which conducts cost-benefit analyses of various social and educational programs to inform state policy decisions
• The What Works Clearinghouse, an initiative of the U.S. Department of Education that reviews and disseminates evidence on effective educational interventions
• The Abdul Latif Jameel Poverty Action Lab (J-PAL), a global research center that conducts randomized evaluations of poverty alleviation programs in developing countries
• The Evidence-Based Policymaking Collaborative, a network of organizations that promote the use of evidence in federal, state, and local policy decisions
• The Behavioral Insights Team (BIT), a UK-based organization that applies insights from behavioral science to improve public services and policy outcomes
• The Pew-MacArthur Results First Initiative, which works with states to implement evidence-based policymaking and invest in programs that deliver the best outcomes

Tools and Techniques

• Logic models that visually represent the theory of change underlying a policy or program, linking inputs, activities, outputs, and outcomes
• Evidence matrices or clearinghouses that summarize and rate the strength of evidence for different interventions in a particular policy area
• Data visualization tools that help policymakers and the public understand complex data and research findings (interactive dashboards, infographics)
• Rapid cycle evaluation methods that allow for quick, iterative testing and refinement of policy interventions in real-world settings
• Collaborative platforms that facilitate data sharing, evidence synthesis, and knowledge translation across different sectors and disciplines
  • Examples include the Evidence-Based Policy Network (EVIPNet) and the Cochrane Collaboration
• Stakeholder engagement techniques that involve citizens, service users, and other affected groups in the policy process (deliberative polling, citizen juries)
• Capacity-building initiatives that train policymakers, researchers, and practitioners in evidence-based methods and foster a culture of evidence use in organizations
• Clearinghouses and databases that provide access to high-quality research and evaluation studies in various policy domains (Campbell Collaboration, Scopus)

Future Trends and Debates

• Increasing demand for evidence-based approaches in the face of complex, cross-cutting policy challenges such as climate change, inequality, and public health crises
• Growing recognition of the need to address issues of equity, diversity, and inclusion in evidence generation and policy development
  • Ensuring that evidence reflects the experiences and needs of marginalized or underrepresented groups
  • Promoting community-engaged research and participatory approaches to policy design and evaluation
• Advances in data science, machine learning, and artificial intelligence that can enable more sophisticated analysis and prediction of policy outcomes
  • Potential to harness big data from social media, sensors, and other sources to inform policy decisions
  • Ethical concerns around privacy, transparency, and algorithmic bias in the use of these technologies
• Calls for greater transparency and reproducibility in research, including open data, pre-registration of studies, and replication of key findings
• Debates around the appropriate balance between evidence and other considerations in policy making, such as values, public opinion, and political feasibility
  • Recognition that evidence is necessary but not sufficient for good policy, and that trade-offs and judgment are often required
• Efforts to build more effective partnerships and knowledge-sharing networks among researchers, policymakers, practitioners, and other stakeholders
  • Emphasis on co-production of evidence and collaborative problem-solving across sectors and disciplines
• Exploration of new forms of evidence and evaluation, such as developmental evaluation, systems mapping, and complexity-informed approaches that can capture the dynamic, non-linear nature of many policy problems
