在一般均衡模型中，个体自愿提供补偿，通过消费垄断竞争企业生产的差异化产品来补偿环境质量的恶化，本文考察了人口规模如何影响补偿和净贡献的均衡水平。结果取决于效用函数的规格。然而，当环境质量收敛到有限水平时，在有许多个人的大型经济体中，偏移量与这一规范无关。在大型经济体中，补偿是积极的，而且“碳中性”是成立的：净贡献为零。并对各参数进行了比较静力学分析。
In a general equilibrium model where individuals voluntarily provide offsets which compensate for degradation of environmental quality by consuming differentiated goods produced by monopolistically competitive firms, this paper examines how the population size affects the equilibrium levels of offsets and net contributions. The results depend on the specification of the utility function. However, when environmental quality converges to a finite level, the offsets are independent of this specification in a large economy with many individuals. Offsets are positive in the large economy, and "carbon neutrality" holds: Net contributions are zero. The comparative statics of parameters are also analyzed.
