In Germany, women currently obtain 40 percent less pension income than men. In collaboration with media companies, corporate partners and financial institutions, the project aims to create a communication toolbox that will inform women on the state of their retirement income and incentivise them to boost their pension planning activities. Academic insights on financial literacy and investment biases of women, especially with regard to pension decisions, shall be used to create the toolbox. In addition, a retirement planning app will be used in the field studies. The toolbox and app will be used to suggest a range of strategies that women can pursue to close the high income gap in retirement.
