According to most economists,

A) command-and-control regulations work better than incentive-based regulations.
B) incentive-based regulations work better than command-and-control regulations.
C) command-and-control regulations have about the same effectiveness as incentive-based regulations.

Most economists believe that incentive-based regulations, such as emissions trading or pollution taxes, are more effective than command-and-control regulations, which specify particular technologies or levels of pollution control. This is because they create an economic incentive for firms to reduce pollution and allow for flexibility in how firms achieve their pollution reduction targets. In contrast, command-and-control regulations can be inflexible and costly for firms to comply with.
