Questions & Answers

Q: How does Bjorn Lomborg suggest prioritizing global issues when determining the best use of $75 billion?

Lomborg suggests using a cost-benefit analysis to determine which solutions will have the greatest impact. By comparing the costs of different interventions to the benefits they will generate, it is possible to identify the most effective ways to spend the limited resources.

Q: What are some of the challenges in improving education quality, particularly in developing countries?

Lomborg explains that improving education quality is a complex issue with no simple solution. Incentive structures and teacher performance are significant factors, but it is challenging to measure and evaluate these factors objectively. Additionally, other interventions, such as nutrition, may have a greater impact on education outcomes, highlighting the need for comprehensive approaches.

Q: What are the potential benefits and challenges associated with implementing a high global carbon tax?

A high global carbon tax would dramatically reduce CO2 emissions and contribute to mitigating the effects of climate change. However, it would also have significant economic costs, particularly in terms of lost GDP growth. Additionally, implementing such a tax would be logistically and politically challenging, especially in countries with limited taxation systems.
