Preferences for Prevention: People Assume Expensive Problems Have Expensive Solutions.

Area of Science:

• Behavioral Economics
• Public Policy
• Disaster Management

Background:

• Public spending on disaster prevention is often inefficient.
• Elected officials' policies reflect constituent preferences, which can be misaligned with optimal resource allocation.
• The "cost conflation" mechanism, where perceived problem cost dictates perceived solution cost, influences these preferences.

Purpose of the Study:

• To formally model collective action influenced by cost conflation.
• To test experimentally how cost conflation biases preferences for disaster prevention spending.
• To understand how this bias leads to inefficient policy and investment decisions.

Main Methods:

• Developed a formal model of collective action incorporating the cost conflation mechanism.
• Conducted an incentivized experiment with subjects to observe their spending preferences.
• Analyzed deviations from theoretical equilibria caused by cost conflation.

Main Results:

• Experimental subjects exhibited cost conflation, linking prevention costs to damage costs despite contrary information.
• Participants underinvested in preventing small disasters and overinvested in preventing large disasters when cheap solutions were available.
• Overemphasis on disaster damages led subjects to perceive disasters as unsolvable, hindering prevention efforts.

Conclusions:

• Cost conflation significantly biases public preferences and leads to inefficient disaster prevention policies.
• Understanding and mitigating cost conflation is crucial for effective disaster risk reduction.
• Policy communication should focus on the feasibility and cost-effectiveness of prevention, not solely on damage severity.
