The Role of Oligarchs in Russian Capitalism
利用独特数据集，描述了俄罗斯经济中的所有权集中程度，发现寡头控制了大量经济资源，其企业相对全球标准并非过大，但运营效率高于其他俄罗斯所有者。
Using a unique dataset, we describe the degree of ownership concentration in Russian economy and its role in shaping economic and political institutions in Russia. In particular, we find that Russian ‘oligarchs’ do control a substantial part of the economy. While the relative weight of their firms in Russian economy is huge, they do not seem to be excessively large by the standards of the global economy where most of them are operating. The oligarchs seem to run their firms more efficiently than other Russian owners controlling for industry, region and size.
