NOTES AND PROBLEMS: A new format for the PROBLEMS AND SOLUTIONS SERIES
介绍了《计量经济学理论》期刊中“问题与解答”系列的新格式，该系列旨在为学生、教师和研究人员提供计量经济学的习题和研究级问题，过去20年成功促进了学术互动。
In establishing the Problems and Solutions (P&S) series of Econometric Theory , the primary objective was pedagogical—to provide an intellectual resource for students, instructors, and researchers through the publication of student exercises and research-level problems in econometrics. Over the past 20 years, the P&S series has successfully served this goal. Large numbers of worked exercises and problems have now been published, and the series has promoted interaction between problem solvers, problem posers, and the ET readership, thereby helping to bring the wider econometric community together in a common purpose.
