Macroeconomics is a branch of Economics that deals with the issues of an economy as a whole, rather than those of individual agents or specific markets. Macroeconomics is concerned with the understanding of aggregate phenomena such as economic growth, business cycles, unemployment, inflation, and international trade among others. These topics are of particular relevance for the development and evaluation of economic policy.

Applied macroeconomics aims to understand and explain this aggregate behaviour by working with the available economic data and applying quantitative and econometric methods to further our knowledge.
