2. Dual PhD in AEREC and demography. 需要在农经PhD的基础上再多修24学分课程（这些课程只能从一个规定的list里面选择，都是很核心难度相对较大的课程）因为有2-3门课程可能和AEREC 重复，所以实际上你需要多修5-6门课程。这个项目的具体情况我不太清楚，但是之前有人完成了这个项目，找到了很不错的faculty的职位。
3. Dual PhD in AEREC and Operations Research. 这个项目的难度很大，比上面这个demography的要难好几倍，因为对数理课程要求很高。需要在农经PhD基础上多修36个学分的课程（也是从一个规定的list选课，都是很难的PhD课程). AEREC也有2-3门课在这个list里面，所以最后你需要多修9-10门课程的样子，基本都是数学系，统计系，和industrial engineering的core courses。此外还要修他们单独开设的四个学期的colloquium (四个学分)，主要是训练各种research的skills，这个四学分倒是容易，但是经常和其他课程冲突，所以挺麻烦的。目前还没有人从这个项目毕业，至少经济类的没有，别的系有，但是都是理工科的。
Econ 500 (PhD level mathematical economics, pretty hard real analysis course)
Econ 501 (PhD level econometrics 1, very hard measure and statistical theory)
Econ 502 (first semester PhD level microeconomics)
AEREC 510 (econometrics 1, more empirical)
AEREC 590 (AEREC colloquium, pretty easy, do some interview, writie some report)
Note: need to apply for grad school exemption for going beyond 12 units if you have a 20 hours assistantship.
第一学年第二学期：
This is the most difficult semester to get through, have to finish 5 core courses.
STAT 515 (stochastic process, core of statistics PhD program, very demanding and hard)
Econ 521A (second semester PhD level microeconomics)
AEREC 511 (econometrics 2, more empirical)
Econ 510 (econometrics 2, more theoretical)
AEREC 597A (applied welfare analysis, PhD level applied microeconomics, recommend to take before the qualify)
Note: need to apply for grad school exemption for going beyond 14 units if you have any kind of assistantship.
Note: you can skip Econ macro classes, which is not required or recommended for this dual program.
第二学年第一学期：
Econ 511 (econometrics 3, more theoretical)

OR (operations research colloquium)
Note: AEREC 519 ( Resource and Environmental Economics I), if possible, take it this year, or defer to next year.
Note: need to apply for grad school exemption for going beyond 12 units if you have a 20 hours assistantship.
第二学年第二学期：
IE 519 (dynamic programming) or IE521 (nonlinear programming, only offered every two years), choose one or both.
AEREC 597B (computatonal economics)
AEREC 533 （Rural Development Research Methods and Topics）or AEREC 541（ Resource and Environmental Economics II）
another course in numerical or simulation methods;
OR (operations research colloquium)
Note: need to apply for grad school exemption for going beyond 12 units if you have a 20 hours assistantship.
第三学年第一学期：
AEREC 597F (Applied Microeconometrics)

Note: need to apply for grad school exemption for going beyond 12 units if you have a 20 hours assistantship.
第三学年第二学期：
another course in numerical or simulation methods;
choose other two classes in economics or econometrics;

开始写毕业论文。
