Economists develop approaches for obtaining the data they need. For instance, sampling methods may be castoff to conduct a survey, and numerous mathematical modeling methods may be used to develop predictions. Making reports, including tables and charts, on research results also is a significant part of an economist's profession, as is presenting economic and statistical ideas in a clear and meaningful mode for those who do not have a background in economics. Some economists also do economic analysis for the media.
Many economists concentrate in a specific zone of economics, although universal knowledge of elementary economic values is essential. Macro economists study the supply and demand decisions of persons and businesses, such as how profits can be maximized and the number of a good or service that customers will demand at a certain price. Industrial economists and organizational economists study the market structure of specific industries in terms of the number of competitors within those industries and inspect the market choices of competitive businesses and monopolies. These economists also may be concerned with antitrust policy and its impact on market structure. Macro economists study ancient movements in the whole economy and forecast future tendencies in areas such as unemployment, inflation, economic growth, productivity, and investment. Monetary economists and financial economists do effort that is alike to that done by macro economists. These work forces study the money and banking system and the effects of fluctuating interest rates. International economists study global financial markets, currencies and exchange rates, and the effects of numerous trade policies such as tariffs. Labor economists and demographic economists study the supply and demand for labor and the determination of wages. These economists also try to clarify the details for unemployment and the effects of varying demographic trends, such as an aging population and increasing immigration, on labor markets. Public finance economists are involved mainly in studying the part of the administration in the economy and the effects of tax cuts, budget deficits, and welfare policies. Econometricians examine all zones of economics and apply mathematical methods such as calculus, game theory, and regression analysis to their research. With these methods, they formulate economic models that help clarify economic relations that can be used to develop forecasts about business cycles, the effects of a specific rate of inflation on the economy, the effects of tax legislation on unemployment levels, and other economic phenomena.
