利用CEMENT.RAW中的数据。
(i)将水泥价格月增长率(gprc)作为供给数量增长率(gce)函数，写出静态供给函数是
其中，gprcpet(汽油价格上涨率)被假定为外生变量，而feb，···，dec为月度虚拟变量。你预期a1和β1的符号是什么？用OLS估计这个方程。供给函数向上倾斜吗？
(ii)变量gdefs是美国真实国防支出的月增长率。gdefs要作为gcem的一个好的工具变量，你需要对它做什么假定？检验gcem是否与gdefs偏相关。(不用担心约简型中可能的序列相关。)你能用gdefs作为估计供给函数中的一个Ⅳ吗？
(iii)谢伊(Shea，1993)认为建住宅楼的产出增长率(gres)和非住宅楼的产出增长率(gnon)是gcem的有效工具变量。其思想是，存在一些应该与供给误差项u，大致无关的需求移动因子。检验gcem是否与gres和gnon偏相关;同样不用担心约简型中的序列相关。
(iv)利用gres和gnon作为gcem的工具变量估计供给函数。你对水泥的静态供给函数得到什么结论？[动态供给函数显然是向上倾斜的;参见Shea(1993)。]
“When I’m on the road driving our taxi I feel very proud，because this is the first taxi service only for women,” says 31yearold Shanti Sharma, who is one of eight female drivers with a taxi service called Cabs for Women by Women.
The last couple of months, since the rape and murder in the city of a college student travelling on a bus, have been particularly busy for her and her colleagues.
“After this case，our workload has increased so much,” says Sharma.“Women who used other cab services are also turning to us now.”
Most women in Delhi say they routinely face harassment(骚扰), and worse, especially on public transport.
Sharma, a single parent with three daughters, has been working as a taxi driver since 2011, when the service was first set up, and it has changed her life. This is the first time that she has earned enough—about 250 a month—to support her family.
Of course, she and the other female taxi drivers are completely outnumbered by male cabbies.“When I park somewhere there are always men there and inevitably five or six of them get together and hang out, ” she says.“I’m usually the only woman in the parking lot, so I just stay inside the car.”
It’s not much better when she is out on the road. Sharma says the male drivers give her a hard time.“As soon as they see a woman at the wheel they start honking(按喇叭) for no reason. They’ll try to overtake you. I’m always worrying about how to avoid getting hit by someone.”
The company behind Cabs for Women by Women, Sakha Consulting Wings, had a number of goals when it set up the service .It wanted to give women from poor backgrounds an opportunity to earn money. By putting women in charge of technologies, it also wanted to change people’s attitudes, and open up boundaries for women.
