Policy instruments can be combined in policy packages. Which statement best captures this idea?

• A. Combining instruments can create more effective outcomes than any single instrument.
• B. Packages are less effective than single instruments.
• C. Policy instruments should never be combined.
• D. Packages only complicate implementation without benefits.

Answer: (A)

Combining policy instruments into packages relies on complementarities: different tools have different strengths and weaknesses, and using them together can address multiple aspects of a problem more effectively than any one tool alone. A price-based instrument, like a tax or cap, creates ongoing incentives to reduce emissions, while standards or regulations guarantee a minimum level of performance and ensure coverage across sectors that might not respond fully to price signals. Adding information, subsidies, or capacity-building can lower transition costs and accelerate adoption. Put together, these tools reinforce each other, close gaps, and often achieve larger, quicker, or more robust outcomes than a single instrument could. Choices that claim packages are less effective, should never be used, or add no benefits miss how these complementarities work. They overlook how different levers can fill different roles, share burdens, and improve overall policy performance, even though such packages can add complexity.
