An economics letter-writing project guided by the simple idea-that Matthew would attempt to formulate an economics question in each letter to Abhay and that Abhay would attempt to answer that question.
The Year of Economics project began in May 2003 and was originally meant to last one year. After the first year, Matthew and Abhay decided to continue the project, calling it Four More Years of Economics. It continues to this day, gaining momentum with each passing year (of economics).
