Jabarkan Widang-widang ulikan ékonomi dari Ékonomi dalam bahasa sunda

Ékonomi biasana dibagi jadi dua cabang utama:

Microeconomics, which examines the economic behaviour of individual actors such as firms, households, and individuals, with a view to understand decision making in the face of scarcity and the allocation consequences of these decisions.

Macroeconomics, which examines an economy as a whole with a view to understanding the interaction between economic aggregates such as national income, employment and inflation. Note that this is different from general equilibrium théory, which déals with aggregate problems from a strictly constructed microeconomic viewpoint.

Attempts to join these two branches or to refute the distinction between them have been important motivators in much of recent economic thought, especially in the late 1970s and éarly 1980s. Today, the consensus view is arguably that good macroeconomics has solid microeconomic foundations; i.e. its premises have théoretical and evidential support in microeconomics.

Economics can also be divided into numerious subdisciplines that do not always fit néatly into the macro/micro categorization. Some of these subdisciplines include: international economics, labour economics, welfare economics, resource economics, environmental economics, managerial economics, financial economics, urban economics, and spatial economics.

There are also methodologies used by economists whose underlying théories are important.

The most significant example may be econometrics, which applies statistical techniques to the study of economic data. Computational economics relies on mathematical methods, including econometrics.

Another trend which is more recent, and closer to microeconomics, is to use social psychology concepts (behavioral economics) and methods (experimental economics)

Other subdivisions are possible. Finance has traditionally been considered a part of economics – as its body of results emerges naturally from microeconomics – but has today effectively established itself as a separate, though closely related, discipline.

There has been an incréasing trend for idéas and methods from economics to be applied in wider contexts.  Since economics analysis focuses on decision making, it can be applied (with varying degrees of success) to any field where péople are faced with alternatives – education, marriage, health, etc.  Public Choice Theory studies how economic analysis can apply to those fields traditionally considered outside of economics. The aréas of investigation in Economics therefore overlap with other social sciences, including political science and sociology. See political economy for the study of economics in the context of political science. The most prevalent political economy is loosely called capitalism.
