Definición: The FDI Confidence Index is an indicator created by A.T. Kearney, a global management consulting firm operating in 40 countries across the world. The index ranks countries on a scale from 0 to 3 based on their attractiveness for foreign direct investments. A score of 3 represents the highest level of confidence. The index is constructed using data from a survey capturing the opinions of senior executives and regional and business leaders from 27 countries with high FDI outword flows. Within the survey, the respondents are asked what is the likelihood to make a direct investment in a given country over the next three years: high, medium, low or "no interest". The individual responses are aggregated to produce a country score.
