区域身份认同与团队劳动供给——基于印度旁遮普人与孟加拉人的实验研究

Regional Identity and Collective Labor Supply——Based on Experimental Study of Punjabi and Bengalis People in India

身份认同及其导致的行为模式越来越受到经济学界的关注。印度是一个在身份认同上极为多元、复杂的国家,但过去的研究主要集中在性别、宗教、种姓等认同上,基于区域的认同还较少被研究。本文运用实验室实验的方法,对印度旁遮普人与孟加拉人进行了一次团队劳动供给的研究。我们运用比较新颖的"食物分组"方法引入区域身份认同,在"最小努力博弈"和"真实劳动"的实验框架下,研究了两个地区的人在不同分组条件下付出的努力水平。我们发现,旁遮普人确实比孟加拉人更为计较经济利益,而较少看重区域身份认同。随后我们用回归方法验证了这个结论,并总结了在包含不同区域人群的团队劳动中,最终影响个人努力水平的主要因素。

Identity and its effects on behavior has attracted more and more interests for economists. India is a country with various identities; the current research focus mainly on gender,religion and caste identity while regional identity has not been studied much. This paper,using methodology of Experimental Study,studies the labor supply of Punjabi and Bengalis People in India. By using food grouping for regional identity,this paper study the labor effort of Punjabi and Bengalis People in India in the framework of the least effort game and real labor.The result is that Punjabi people values economic return more than regional identity comparing with Bengalis. This paper also verifies this conclusion by regression approach.
