摘要
En 中文
The ownership of a quoted company is usually spread among various shareholders. This dispersion can be characterized by an oriented network, whose nodes represent the companies, and an arc between companies i and j, with weight s(ij), indicates that company i owns s(ij) percent of company j, being denoted by stock shareholding network (SSN). Given two sets of companies T and C-0 from a SSN, we say that the companies in C-0 control those in T if they own or imply ownership of at least aj percent of companies' T shares. So, given a targeting set T, our problem is to find a set of companies C-0 in which we invest such that the entire investment cost is the lowest. This problem has relevant applications in corporate governance and it can be modeled within network optimization. We discuss its applicability using a broad set of companies in the European stock market.
