positive economics

Positive economics focuses on establishing facts and objective analysis, distinguishing itself from normative economics, which deals with policy and value judgments. It seeks to answer questions like "If subsidies are given to butter producers, will the price of butter decrease?" or "Will currency devaluation improve a country's balance of payments?". The goal is to derive conclusions independent of personal biases, though economists acknowledge that ideological leanings can influence the questions asked and the interpretation of data.123

Economists use statistical inference and models to test hypotheses, comparing predictions to real-world events. While this process involves uncertainty, it aims for value-free conclusions. Positive economics is crucial for defending against special interests and maintaining professional standards within the discipline.123
