Says GgK: according to GfK, the purchasing power of Europeans has increased on an average of 4.2%. But the purchasing power differs substantially in the several countries. In 2015, disposable income in eastern and western European countries lags behind Western and Northern Europe. But despite an unfavourable economic environment, these countries record a slight growth of their people’s purchasing power in 2015. According to the market research company, a total of approximately €9.13 trillion is available to European consumers in 2015 for spending and saving.
