Approach
Proposition An Investment Model Can Help
- improve public policies by focusing decisions on
evidence-based and cost-beneficial options - identify gaps in current knowledge and
- put prevention and intervention on an
equal analytical and policy-setting playing
field.
Topics for Today
- Our general analytical approach
- Our experience in Washington State supplying the
legislature with investment information - Examples in 2 policy areas crime and prevention
- How the legislature has used the information

Overview
- Recent Directions to WSIPP from the Legislature
- What Works, What are the Costs Benefits?
- The legislature has asked WSIPP to examine
options affecting - Crime (1994, 1999, 2003, 2005, 2009),
- Education, Early Education (2003, 2006, 2007,
2009), - Child Abuse Neglect (2003, 2007, 2009,
- Substance Abuse (2003, 2005, 2009),
- Mental Health (2005, 2009),
- Developmental Disabilities (2008),
- Employment (2009),
- Public Assistance (2009),
- Public Health (2009), and
- Housing (2009)
- What Difference Could an Evidence-Based Strategy
Make to Washington? - Can a investment portfolio of evidencebased
options affect statewide outcomes and save
taxpayers money?

What Works? Definition of Evidence.
- Standards of Evidence
- Petri dish experiments
- Real-world random assignment experiments
- Real-world natural experiments
- Statistically well-controlled comparisons
- Not so well-controlled comparisons
- Anecdotes
-
1. WSIPP researcher gathers all the studies she
can locate on a topic.
2. She applies standards of evidence to
identify the high quality studies.
3. She meta- analyzes all high quality studies to
estimate an average effect.

The Big Picture Crime Rates Taxpayer Costs
1980 to 2007
In 1980, taxpayers spent 557 per household on
the criminal justice system. Today they
spend 1,223 per year. A 120 increase.
In 2007, crime rates were 39 lower than they
were in 1980.

Evidence-Based Policy Options That Reduce Crime,
but at Less Cost? Our 3-Step Research Approach
- What works what doesnt?
- We locate rigorous (comparison group), real world
evaluations of adult and juvenile corrections
programs, prevention. (571 studies to date)
- What are the economics of each option?
- We estimate the taxpayer and crime victim
benefits and costs to people in Washington -
- Statewide, how would alternative portfolios
affect prison demand, public spending, crime?

ISP treatment -17.1 (11) 11,563
- We located and analyzed 57 rigorous drug court
outcome evaluations conducted in the United
States. -
- On average they reduced recidivism rates 8
percent. - Without drug court, an offender has a 58 chance
of being reconvicted for a new felony or
misdemeanor after 13 years - With drug court, the odds drop to about 54.
- The reduced recidivism generates a NET gain of
4,767 per drug court participant. - We estimate drug courts cost 4,333 more per
person than regular court processing (court
costs, treatment) benefits of reduced recidivism
total 9,100 to taxpayers (lower criminal justice
costs) and crime victims (reduced victimization).

The Crime Example Washington State Legislative
Response
- Started funding juvenile justice EBPs in late
1990s. - 2007 Legislature made a substantial change by
funding a portfolio of evidence-based adult and
juvenile corrections, and prevention. - One planned prison taken off the drawing board.
- Juvenile facilities closed, another adult
facility to be closed. - 2009 Legislature, even amidst other budget cuts,
continued to fund the evidence-based portfolio.

Actions Taken or Underway in Washington
- MORE COMPHENSIVE RESOURCE PORTFOLIOS
- 2007 and 2009 Legislatures have funded longrun
crime portfolio adult juvenile offender
programs, and prevention. - Legislature added early childhood education to
the states basic education definition. - Other funding changes in prevention/intervention
programs - OTHER IMPLEMENTATION ACTIONS
- For EB Programs A state-adopted evidence-based
list, coupled with local government choice (from
the list). - For New Ideas A research development funding
level set by the state for local initiatives
state evaluation. - Formal statewide assessment tools
(to align the programs
and the participants). - Program quality assurance provided by state.

- Producing Effect Sizes Two Types
-
- What works inventory. What does not work?
What dont we know? - e.g., do home visitation programs affect child
abuse rates? - Blueprint findings when possible and
meta-analysis - Linking effect sizes.
- Do measured outcomes link to other outcomes of
interest? - e.g., does child abuse affect later schooling
outcomes, criminality, substance abuse, etc.?
- Statewide Effects of an Evidence-Based Strategy
-
- What is the size of the market for
evidence-based options? - Size of statewide population that could benefit
and effective prg. - Proportion currently untreated
- Realistic expansion potential
diminishing returns - Bottom Line Estimates
- Meaningful state-level outcomes
- e.g., change in crime rate, child abuse rate,
prison construction , net fiscal gain, etc.
- Turning Effect Sizes into Dollars
(ROI) -
- What costs are avoided (or benefits gained)?
- Information needed
- Population characteristics
- e.g., child abuse prevalence
- System responses (cases costs)
- e.g. costs of crime, child welfare
- Economic information
- e.g. labor market data
- Costs of Programs
- e.g. cost of home visitation
- Consistent calculations of cash flows ROI and
risk.
