Microeconomics consists of an interdisciplinary approach to studying individual decision-making. It primarily studies the economic process by which individual choices affect societal outcomes, and it examines the impact of those choices on other people and institutions. In doing so, it explores how an individual's choice structure affects the choices they make and the circumstances in which they choose.
Macroeconomics on the other hand is an approach to economics that concentrates on the larger macroeconomic framework in which individuals and institutions interact within the economic system. It is not concerned with individual decisions, but rather how these choices will affect other people and institutions. The macroeconomist does not necessarily focus on the small-scale microeconomists do, but instead applies microeconomics as a model to other models of the macroeconomy.
Micro and macro economics can be compared by noting that both have their own sets of assumptions, and both use different methods of presenting their results. In a macro, the assumption is that the behavior of the economy is governed by the overall economic environment in which the economy exists. In micro, the assumption is that behavior is governed by the microeconomic conditions. In both cases, the underlying assumption is that there are some universal laws that govern how humans behave with one another and the economy in which they live.
Macro models are generally thought of as being less complicated, and this is true. This is because they are based on concepts that are relatively simple. The macro model, however, assumes that the economy and its behavior are a single whole system. The macroeconomist assumes that a simple model of the economy that includes everything will provide the necessary data for making an accurate prediction. This model also has the assumption that human beings have an intrinsic desire to pursue economic goals, regardless of what those goals may be.
Micro models, on the other hand, are more complex. They are based on more complex concepts and allow for more complex models of the economy and human behavior. The model assumptions that are used within a micro model of microeconomics include the fact that people will not act in ways that will directly benefit themselves or those they care about, but rather will seek out the best options available to them. for their self-interest. Furthermore, the microeconomist assumes that people will have an intrinsic need to use their knowledge to help create a better world for future generations.
In a nutshell, microeconomics and macroeconomics are two separate theories, with each theory focusing on the relationship between micro and macro economics. Microeconomists, who are most often called microeconomists, attempt to analyze the macroeconomic context surrounding the micro-economic decisions made by the individuals. Microeconomists then use those decisions as the basis for making macro economic predictions. This information is then used to formulate macroeconomic predictions on the macroeconomic environment where those same micro-economic factors are found.
