Math/Physic/Economic/Statistic Problems

The problem set 2 has been posted. There is a section where you need to work with OECD data. Professor recommend to check it out right away. Try to get the data in case you have problems. The data may be available on FRED(https://fred.stlouisfed.org/) as well. Do not use data for the United States. And I also attached excel file that I received from Professor and also file describing how to use FRED website.
