Narrow Replication of Fisman and Miguel's (2007a) ‘Corruption, Norms, and Legal Enforcement: Evidence from Diplomatic Parking Tickets’
狭义复制了Fisman和Miguel关于联合国外交官腐败行为的研究,使用零膨胀负二项模型重新估计,确认了原结论,但强调需考虑零结果的不同生成过程。
This note provides a narrow replication of Fisman and Miguel's (Journal of Political Economy, 2007a; 115(6): 1020–1048) original findings about estimating negative binomial count models to study corruption practices among United Nations diplomats. We present estimates based on zero-inflated count models, given the possible presence of excessive zero counts in the dependent variable of the main specifications. Our results confirm Fisman and Miguel's original findings. However, they also suggest the importance of considering distinct generating processes for zero outcomes. We cannot reject hypotheses favoring the use of zero-inflated negative binomial models over its simpler versions in this context. Copyright © 2016 John Wiley & Sons, Ltd.
