We get a lot of invitations for Bjorn, so many that he wouldn't have time for his research, our think tank's projects, or writing opeds and articles in the media. We've decided to use the market forces by charging a rather steep fee, all of which goes to the nonprofit Copenhagen Consensus Center.

Thank you for your interest, however, unfortunately, Bjorn gets a lot of requests regarding school and university assignments from all around the world. Instead of spending days on answering everyone's requests, Bjorn writes columns for newspapers around the world, and posts commentary almost daily on Facebook and Twitter.

You can find lots of video interviews here as well as some of his talks.

As for researching particular charities, we have made the strategic decision to focus our cost-benefit analysis efforts to solutions, which then can be implemented by governments and/or philanthropists. It is a huge enterprise to keep up to speed with how different charitable organizations perform, and even harder to predict what they will do in the future.

Here are some other organizations in this space that we like:
