Data for ‘social networks, identity and economic behavior: empirical evidence from India’, (2010, Cornell University).

IntroductionThese data were collected in the framework of Dr. Annemie Maertens’ PhD dissertation during the period August 2007 – July 2009. The dissertation was undertaken from Cornell University, but executed in India in collaboration with the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT). The project was sponsored through an NSF Doctoral Dissertation Improvement Grant (Grant No. 0649330).The main goal of this project was to collect and analyse household survey data in the Indian states of Andhra Pradesh and Maharashtra in order to gain a better understanding of the role of social networks and identity in economic decision-making. The first panel of this research studied the role of social learning and social pressures in Bacillus thurigiensis (Bt) cotton adoption using data from three villages (Aurepalle, Kanzara and Kinkhed). The second panel of this research studied the role of social norms in educational decisions and aspiration using data from three villages (Dokur, Kalman and Shirapur).The data collection consisted of five phases: (1) qualitative round (to determine the topic of the two panels); (2) trial round (to field test the questionnaires); (3) training round (to train the enumerators); (4) quantitative collection round (to collect the household level, village level data); (4’) data entry of (4) ; (5) data validation round (to collect additional data to correct the missing variables and inconsistencies uncovered in (4’)).The villages selected for this study are part of the Village Level Studies (VLS) program ICRISAT. In this program, ICRISAT followed 300 randomly selected households from six villages during the period 1975-1985 every three weeks. In 2001, ICRISAT restarted the panel, revisiting 185 of the first generation VLS households and their split-offs, in addition to 261 newly added households.

引言
本数据集采集工作依托安妮米·梅尔滕斯（Annemie Maertens）博士的博士论文完成，采集时段为2007年8月至2009年7月。该论文由康奈尔大学（Cornell University）立项，实际调研工作在印度开展，合作方为国际半干旱热带作物研究所（International Crops Research Institute for the Semi-Arid Tropics, ICRISAT）。本项目由美国国家科学基金会（National Science Foundation, NSF）博士论文改进资助项目（资助编号：0649330）资助。

本项目的核心目标为在印度安得拉邦（Andhra Pradesh）与马哈拉施特拉邦（Maharashtra）采集并分析家庭调研数据，以期更深入理解社会网络与社会身份在经济决策中的作用。本研究分为两个面板数据模块：第一模块基于三个村庄（奥雷帕莱、坎扎拉、金克赫德，Aurepalle, Kanzara, Kinkhed）的调研数据，探究社会学习与社会压力在转苏云金杆菌（Bacillus thurigiensis, Bt）基因棉花的种植采纳行为中的作用；第二模块基于另外三个村庄（多库尔、卡尔曼、希拉普尔，Dokur, Kalman, Shirapur）的调研数据，研究社会规范在教育决策与教育期望中的作用。

本次数据采集分为五个阶段：（1）定性调研阶段：用于确定两个面板数据模块的研究主题；（2）预调研阶段：对调查问卷进行实地测试；（3）访员培训阶段：对调研访员开展专业培训；（4）定量数据采集阶段：采集家庭层面与村庄层面的调研数据；（4’）数据录入阶段：完成阶段（4）所采集数据的录入工作；（5）数据校验阶段：补充采集必要数据，以修正阶段（4’）中发现的变量缺失与数据不一致问题。

本次研究选取的村庄均属于国际半干旱热带作物研究所（ICRISAT）的村级跟踪研究（Village Level Studies, VLS）项目样本。该项目于1975年至1985年间，每三周对六个村庄中随机抽取的300户家庭开展跟踪调研。2001年，ICRISAT重启该面板研究项目，除新增261户家庭外，对初代VLS项目中的185户原受访家庭及其分户家庭进行了回访。当前该数据采集工作仍在持续中：
