This technical note is introductory to a course on the economic environment of businesses. It provides an overview of the main problems of the economic environment, some explanatory ideas and models and a first glance at the main macroeconomic issues: growth and the cycle, unemployment, inflation, public deficit and structural deficit. Some ideas on government intervention in the economy and the global economic environment are also presented.
In the second part, the characteristics of the main models that are used in the analysis of the economic environment of businesses are presented and the main indicators of economic output are defined: income, expenditure, prices and population. We will start from the circular flow of income model, the version that distinguishes the goods market from the factory one as well as the macroeconomic adaptation that identifies the moment of expenditure, output and income. After defining the main variables, the various models that are usually used are briefly reviewed. Some concepts on the analysis of the datasets are provided before. At the end, a number of important clarifications are explained to avoid different economic concepts from being misunderstood.
On the last pages, an overview of building the aggregate supply and aggregate demand model is provided. We will use it as the basis for understanding how the economy works as a whole.
