The literature review revealed four main types of financial networks: cross-shareholding, correlation, debt, and Granger-causality. Four equity-based directed financial networks were constructed. The two key network measures used in this research are PageRank (risk exposure and network importance) and modularity class (community detection).}, title={A financial network analysis of the equity linkages in Poland}, type={artykuł}, keywords={network analysis, equity linkages, PageRank, modularity, WIG, analiza sieciowa, powiązania kapitałowe, Warszawski Indeks Giełdowy}, }
