A lack of knowledge of basic financial concepts and lack of confidence are likely to reduce women's ability to access and use appropriate financial products and opportunities. It may also reduce their ability to set up a small business, build up emergency savings, save for retirement, and choose the best financial products for their needs. Women need to improve their financial literacy even more than men in order to address the challenges they face in achieving financial well-being (OECD, 2013). The OECD/INFE data collection in 2010/11 provided a first international comparison of gender difference in financial knowledge for 14 countries (Atkinson and Messy, 2012, OECD, 2012), while the OECD/INFE 2015 survey covered some 30 countries and economies (OECD, 2016). Figure 10.1 shows the difference in the percentage of men and women who can correctly answer at least five questions out of seven on financial knowledge.
