Agricultural economics is a complex branch of economics and may be subdivided into three following categories.
(1) Disciplinary work: improvement of theories, techniques and descriptive knowledge of economics and its contributing disciplines such as statistics, mathematics and philosophy. (2) Multi-disciplinary subject matter areas: energy, technical change, institutional change, natural resources, farm management, rural communities, marketing, human development and the environment - areas which are important to fairly well-defined groups of public and private decision-makers facing well-defined sets of problems. (3) Problem solving: the definition, solution and management of specific practical problems. Work in each of these three categories may deal with teaching, extension and out-reach, consulting, advising, entrepreneurship and administration, as well as research. All of these may require knowledge of values, non-monetary as well as monetary.
Each country has certain distinguished features concerning agriculture which are conditioned by the geographical location.
