For all the tasks below only use scatter plot diagrams with quarterly or yearly data for at least 30 years.

1. Plot the real GDP for your country and add an exponential trend line with its equation, which reflects the potential GDP. Analyze briefly your graph highlighting periods of recession and expansions, as well as finding the long run economic growth rate.

2. Plot the unemployment rate and find the natural rate of unemployment by adding a linear trend with its corresponding equation to your graph. Briefly analyze your graph by calculating the cyclical unemployment in every period, as well as finding any relation between the graph of the real GDP above and the graph of unemployment rate. Remember the class discussion on the relation between the business cycle and unemployment rate.

3. Using real (or constant prices) household Consumption and your data on real GDP, plot the relation between real Consumption (on the y-axis) and real GDP (on the x-axis) and find the MPC using a linear trend line. Keep in mind that the frequency of the data for both consumption and GDP must be the same (e.g., quarterly or yearly), and that you need to use constant prices of the same year for both variables (e.g., Consumption and GDP, at constant prices of 2005, or 100-2005, or any other year available).
