Final answer:
Economics is the social science discipline that explores financial motives and decisions, focusing on the economy as a whole or in aggregates through subfields like macroeconomics.
Step-by-step explanation:
Economics is the discipline that examines either the economy as a whole or its aggregates. This field of study can be broken down into two main subfields: macroeconomics and microeconomics. Macroeconomics concerns itself with the aggregate demand/aggregate supply model and economic measures such as gross domestic product (GDP), examining the economy on a national or global scale. Microeconomics looks at the decision-making processes of individuals and businesses. By using various models and theoretical frameworks, economists aim to understand and predict economic behavior and outcomes.
