Public sector transparency and countries' environmental performance: A nonparametric analysis, MPRA Paper 39553, University Library of Munich, Germany.

Based on the theoretical background of the link between countries’ transparency and environmental policy our paper provides empirical evidence for a sample of 68 countries for the time period of 2001-2010. By assuming that countries’ transparency levels shape their environmental policy which reflects upon their environmental performance levels, we develop an empirical model for investigating such a relationship.
