What if your donation could achieve 100 times more?
“100x mehr” (“100x more”) tells the stories of people who set out to find where help achieves the most – and shows how you can use what they learned for your own giving.
For now, the book is available in German only.
“Do you really want to make a difference with your money? Then read this book.”
Rutger BregmanHistorian and bestselling authorBy carefully applying scientific insights, donations can have an impact a hundred times greater. This is a pivotal turning point for ordinary people who want to make the world a better place.
Michael KremerChief Economist of the World Bank and Nobel laureate in economicsWhat it’s about
Not every donation has the same impact.
Most of us give from the gut – to whichever project moves us at the moment. Yet aid programmes differ enormously in what they achieve with the same euro.
How big these differences are, why the charity market doesn’t even them out by itself – and how to find the most effective organisations: that is what this book is about. Not by wagging a finger, but through stories.
