Cartelization and firm performance in Upper Silesia 1880–1913
研究了20世纪初上西里西亚煤炭卡特尔（上西里西亚煤炭公约）对企业效率的影响，发现卡特尔并未显著降低矿山的技术效率，这一结果与先前研究一致。
Abstract In this article the effects of cartelization on firms’ efficiency are investigated using the example of an early twentieth century coal-mining cartel in Upper Silesia: the Upper Silesian Coal Convention. Established in 1898, the cartel comprised various types of private, as well as state-owned, mining enterprises. Using a microeconomic dataset based on firm-level data of the Upper Silesian mines, I focus on the cartel’s effect on efficiency. The cartel did not significantly reduce technical efficiency among mines. This finding confirms previous research on cartels’ effects on efficiency.
