A more thorough explanation:

Term: EX ANTE
Definition: Ex ante means making decisions based on assumptions and predictions about how things will happen in the future, rather than looking back in hindsight. It is a subjective and prospective approach.
Example: Before investing in a new business venture, the investors conducted an ex ante analysis to predict the potential risks and returns. They made decisions based on their assumptions about the market and the economy.
Explanation: The example illustrates how ex ante is used to make decisions based on assumptions and predictions about the future. The investors did not have any actual data or experience to rely on, so they had to use their subjective judgment to make decisions. Ex ante analysis is commonly used in financial and economic decision-making.
