Washington State Institute for Public Policy

Benefit-Cost Results

Since the 1990s, the Washington State legislature has directed WSIPP to identify “evidence-based” policies. The goal is to provide Washington policymakers and budget writers with a list of well-researched public policies that can, with a high degree of certainty, lead to better statewide outcomes coupled with a more efficient use of taxpayer dollars.

Research Approach. WSIPP has developed a three-step process to draw conclusions about what works and what does not to achieve particular outcomes of legislative interest. First, we systematically assess all high-quality studies from the United States and elsewhere to identify policy options that have been tested and found to achieve improvements in outcomes. Second, we determine how much it would cost Washington taxpayers to produce the results found in Step 1, and calculate how much it would be worth to people in Washington State to achieve the improved outcome. That is, in dollars and cents terms, we compare the benefits and costs of each policy option. It is important to note that the benefit-cost estimates pertain specifically to Washington State; results will vary from state to state. Third, we assess the risk in the estimates to determine the odds that a particular policy option will at least break even. ...show more
