I believe the correct answer to the question is:
Economists believe that people respond to monetary incentives. This means that individuals are more likely to adjust their behavior based on financial rewards or penalties. For example, if the government offers tax incentives for buying electric cars, people may be more inclined to purchase them to benefit from the financial incentive.
While speeches from politicians and requests from policy makers can also influence people's decisions to some extent, monetary incentives have been shown to have a significant impact on behavior and decision-making in various economic scenarios.
