How smart phone e-learning influence economic development? What is Macroeconomics? Macroeconomics is a branch of economics that studies how the aggregate economy behaves. In macroeconomics, economy-wide phenomena are examined such as inflation, price levels, rate of economic growth, national income, gross domestic product (GDP), and changes in unemployment.On the other hand, microeconomics looks at the behavior of individual actors in an economy (like people, households, industries, etc). Macroeconomics is the branch of economics that deals with the structure, performance, behavior, and decision-making of the whole, or aggregate, economy, instead of focusing on individual markets.The two main areas of macroeconomic study are long term economic growth and shorter term business cycles. There are two sides to the study of economics: macroeconomics and microeconomics. As the term implies, macroeconomics looks at the overall, big picture scenario of the economy. Put simply, it focuses on the way the economy performs as a whole, and then analyzes how different sectors of the economy relate to one another to understand how the economy functions. This includes looking at variables like unemployment, GDP, and inflation. Macroeconomists develop models explaining relationships between these factors. Such macroeconomic models, and the forecasts they produce, are used by government entities to aid in the construction and evaluation of economic policy, by businesses to set strategy in domestic and global markets, and by investors to predict and plan for movements in various asset markets. Given the enormous scale of government budgets and the impact of economic policy on consumers and businesses, macroeconomics clearly concerns itself with significant issues. Properly applied, economic theories can offer illuminating insights on how economies function and the long-term consequences of particular policies and decisions. Macroeconomic theory can also help individual businesses and investors make better decisions through a more thorough understanding of what motivates other parties and how to best maximize utility and scarce resources.It is also important to understand the limitations of economic theory. Theories are often created in a vacuum and lack certain real-world details like taxation, regulation and transaction costs. The real world is also decidedly complicated and their matters of social preference and conscience that do not lend themselves to mathematical analysis.
