利用WAGEPAN中数据。

(i)利用混合最小二乘法(pooledOLS)估计一个log(ag为被解释变量的方程。以educ，black，exper，married，union以及一系列时间虚拟变量(以1980年为基年)为可解释变量，解释及讨论变量married和union的系数。

(ii)解释为什么通常(i)中标准误总是偏小。算出关于married和union两个变量对自相关和异方差一稳健的标准误。

(iii)现在对变量lwage，exper，married和union进行一阶差分。(不随时间改变的变量educ，black和hisp被排除在这个估计之外，exper也是，因为它总是随着年份增加。)注意排除首年即1980年的一阶差分，因为不存在更早的年份。

(iv)就作回归分析，确保包括一个常数项和一个从1982年到1987年的时间虚拟变量。算出Δmarried和Δunion的系数和标准误。

(v)对比婚姻状况和工会保费的估计水平及其一阶差分估计，并作相应评论。

ouse which was sort of like a small hotel, but it wasn't a very fancy place. Anyway it was a very hot night that night. It was a very hot climate and it was really hot that night. We wanted to have the windows open, but the problem was we had everything we owned right there in the room. The windows didn't have any screens or anything. So anybody could just come right in and steal our things.But if we shut the windows, it would be impossible to sleep. It was way over a hundred degrees Fahrenheit or forty degrees centigrade.

So we decided to put a lot of pots and pans like that under the window. Then if a thief came in, the pots and pans would fall down and we would wake up. That's what we did. Anyway, we were asleep.

All of the sudden in the middle of the night, sure enough, I hear the pans crash.I sat up in bed. My heart was beating like anything. I could see that there was a man in a white robe standing up next to the bed. I tried to scream and I had laryngitis which means my voice wasn't working. And I was screaming in the local language for help. It was like "help help", but I couldn't scream.

So the man came over and he shoved me down on the bed. Then he says in English "be quiet." Then I realized it was my husband, huh… And when I was able to speak, I asked, "What are you doing"

He said, "well, I had a headache and I wanted to get up and get some aspirins."
