The important and relevant of the study of economics?

Many, if not most, of the nation's and the world's most significant social problems have an economic dimension. Microeconomics provides the tools to analyze the trade-offs that individuals, firms, and governments confront because of limited resources. It considers the choices that are made, the social context in which they take place and the implications for human welfare. Economists apply these tools to study a wide range of controversial public policy questions, including environmental regulation, government restrictions on domestic and international markets, the structure of the legal system and the design of tax policy. Macroeconomics explores the sources of economic growth and the causes of recessions and inflation. Macroeconomic analysis assesses monetary policy, explains the performance of financial markets, and considers international trade and financial links.
