This study examines the recent literature on the expectations, beliefs and perceptions of investors who incorporate Environmental, Social, Governance (ESG) considerations in investment decisions with the aim to generate superior performance or make a societal impact. Through the lens of equilibrium models of agents with heterogeneous tastes for ESG investments, green assets are expected to generate lower returns in the long run compared to their non-ESG counterparts. However, in the short run, ESG investments can outperform non-ESG investments through various channels. Empirically, results for the relative performance to ESG investment are mixed. We find strong empirical evidence in the literature that investors have a preference for ESG and that their actions can generate positive social impact through engagement. The shift towards more sustainable policies in firms is motivated by the increased market values and the lower cost of capital of green firms driven by investors’ choices.
I review the literature on eCommerce platforms with particular emphasis on the antitrust debate on Amazon. The business model of hybrid marketplaces is based on monetization through fees on third party sellers hosted on the platform and direct margins on own products. Recent theoretical and empirical work on endogenous marketplace structures has analyzed the welfare impact of the dual mode and of recommendation algorithms that have been associated with self-preferencing strategies. The trade offs are complex and one cannot easily conclude that Amazon entry is biased to expropriate third party sellers or that a ban on dual mode, self-preferencing or copycatting would benefit consumers.
Behavioral finance has emerged from the divergences observed to explain and address the traditional theories of finance and serves as supplement to classical finance by introducing behavioral aspects to decision-making. This study provides academics with a comprehensible and complete synopsis of the evolution of behavioral finance, as well as critical insight is provided. The synopsis was based on the search for publications in Web of Science (WoS) and Scopus and the use of R, Gephi and Tree of Science -ToS- software, using citation analysis, graphos and classification analysis. The results showed psychological aspects, investment in stocks and cognitive biases with the highest visibility. A tree-like structure of hierarchization was developed by ToS. The clusters of publications with the greatest literary contribution were analyzed and the publications with the greatest visibility in each cluster identified. This study provides insights into the current trend in finance towards better understanding of the essential factors in the investor´s decision making.
