Drawing from the idea that income distribution is affected by imperfect market competition, this article examines the effect of a wood market cartel, where roundwood buyers illegally exchanged price information in Finland during 1997–2004. Prices before, during, and after the infringement period are examined using a comparator-based econometric approach with indicator variables in single-equation cointegrating models and in a seemingly unrelated regressions model. Using monthly data during 1996–2012, we investigate the prices of four softwood assortments, pine logs and pulpwood, and spruce logs and pulpwood, consisting of the majority of the industrial wood volume traded in the Finnish wood market. The results suggest that the price of pine pulpwood was statistically significantly affected and that the reduction in the price of pine pulpwood due to the infringement was on average about 10% over the 1997–2004 infringement period.

从收入分配受不完善的市场竞争影响的观点出发，本文考察了木材市场卡特尔的影响，在该市场中，圆木买家在1997-2004年期间非法交换了价格信息。在单方程式协整模型和看似无关的回归模型中，使用基于比较器的计量经济学方法，使用指标变量对侵权之前，之中和之后的价格进行了检查。利用1996-2012年期间的月度数据，我们调查了四种软木分类的价格，松木和纸浆木，云杉的原木和纸浆木，它们构成了芬兰木材市场上大部分工业木材的交易量。
