Finance is a sub-field of economics. Since finance deals with the future, the discipline spans the fields of statistics, econometrics, probability theory, and decision-making under uncertainty.
The field of finance is broadly divided into three areas: asset pricing, corporate finance and market microstructure. Each of these areas has both a theoretical and empirical side, with researchers often specializing in one or the other.
Research in asset pricing deals with the process of price formation in the capital market. Models are proposed that help explain why the prices of two assets differ at any point in time and through time. These models focus on identifying the nature of the risk exposure that the asset has and the economy-wide reward for risk. Both the risk exposure and the reward for risk can vary through time.
Corporate finance deals with such issues as capital budgeting (deciding which projects to take), capital structure (the choice between debt and equity financing), the impact of taxes, dividend policy (what fraction of earnings should be paid out to stockholders), and corporate restructuring (mergers, acquisitions and divestitures). As with asset pricing, researchers in corporate finance tend to specialize in either theoretical or empirical work. Most working in the area focus on empirical corporate finance, examining the market reaction to a host of corporate transactions and events. In most instances the empirical work involves testing the implications of competing theories developed by others.
The newest field in finance is market microstructure. This sub-field deals with how capital market traders interact with each other. Of prime concern is how information is gathered and processed by capital market agents - the process by which information possessed by "informed" investors gets reflected in security prices.
