Like week 1 this week was also very interesting for me. I learned a lot of things from this week. The course materials for this week are really very informative. From this week I knew the difference between Microeconomics and Macroeconomics. Microeconomics studies the behavior of individual firms whereas Macroeconomics studies the activities of the overall economy including unemployment, inflation, etc. The most interesting thing I learned from this week is the circular flow diagram which shows the dependency between firms and households, and how the factor market and goods market works. I know the most important thing from this week is the concept of GDP, Gross Domestic Product. I knew why consumption, investment, government expenditure, and net exports are the components of the GDP.
