We propose two lines of research. In the first line we are interested in analyzing (i) the endogenous formation of common ownership structures, (ii) how common ownership affects the determination of the sequence of competition and the incentives for firms to adopt new technologies, and (iii) how different overlapping ownership structures in, on the one hand, producing companies that negatively affect the climate and the environment, and, on the other hand, companies that
rely on a protected climate and clean environments, affect the objectives and incentives of both industries and thereby affects sustainability. In the second line of research, we focus on the impact of blockchain technologies on markets and finance, and on the recent uprise of new ways of financing companies and startups, by-passing standard institutions as venture capitalists and (central) banks. We are interested in decentralized finance as in investment-based crowdfunding, where many small investors finance a company or project, and also in cryptocurrencies (and blockchain technologies), where many so-called miners or validators (under proof of stake consensus algorithm) certify transactions and compete with traditional banks and registries.
