Microeconomics.

The word "micro" means small, and microeconomics means economics in the small. The optimizing behavior of individual units such as households and firms provides the foundation for microeconomics.
Micro economists may investigate individual markets or even the economy as a whole, but their analyses are derived from the aggregation of the behavior of individual units. Microeconomic theory is used extensively in many areas of applied economics. For example, it is used in industrial organization, labor economics, international trade, cost-benefit analysis, and many other economic subfields. The tools and analyses of microeconomics provide a common ground, and even a language, for economists interested in a wide range of problems.
At one time there was a sharp distinction in both methodology and subject matter between microeconomics and macroeconomics.
The methodological distinction became somewhat blurred during the 1970s as more and more macroeconomic analyses were built upon microeconomic foundations. Nonetheless, major distinctions remain between the two major branches of economics. For example, the microeconomist is interested in the determination of individual prices and relative prices (i.e. exchange ratios between goods), whereas the macroeconomist is interested more in the general price level and its change over time.
