Networks in the balance: an agent-based model of optimal exploitation

Autor(es):
Fernando Anjos (Nova SBE); Ray Reageans (MIT Sloan School of Management)

Resumo (in English only):
A fundamental driver of value creation is that firms have access to high-quality information to guide investment decisions. There are many sources through which firms can access information, one being the social networks that form within an organization. Previous research has emphasized both the importance of investment decisions and also the key role played by worker and managerial social networks in within-firm information diffusion. Our paper studies a hitherto neglected question, specifically whether and how the firm's investment policies can themselves shape the workers' social network and, therefore, information quality.

The main result of our model is that the pursuit of high-quality investments---identified via an existing social network---can under certain conditions compromise the sustainability of such network, thus limiting the firm's long-run level of information quality and investment performance. We further show that in such environments, managers should limit how much they exploit current information, in order to preserve some of the learning afforded by the network. This result is a possible rationalization for the prima facie "socialist" investment policies documented by existing research.

FinTech Report

Autor(es):
Nova Finance Knowledge Center; NOVAFRICA Knowledge Center

Resumo:
O relatório analisa o ecossistema FinTech em Portugal e Espanha (Ibéria) para aferir a dimensão e as características do mercado FinTech nesta geografia. O relatório começa por apresentar os ecossistemas FinTech Global e Europeu para depois mergulhar mais fundo no ecossistema FinTech ibérico, com particular enfoque  sobre setores, quota de mercado e dados financeiros, bem como apresentações dos principais players de Portugal e Espanha e entrevistas com FinTechs e financeiros instituições. O objetivo deste relatório é compreender o ecossistema ibérico FinTech e o futuro dos FinTechs na região.

A segunda parte do relatório analisa o sistema financeiro em África, onde mais de 60% da população adulta da África subsariana não tem conta bancária. Neste contexto, as oportunidades de crescimento para as FinTech em África são enormes. África vive uma explosão demográfica e a taxa de penetração de telemóveis é extraordinariamente alta. As FinTech são uma oportunidade para saltar etapas no desenvolvimento financeiro e estimular a inclusão financeira.

A África do Sul, o Quénia e a Nigéria lideram a África subsariana como centros de FinTech, de acordo com o Índice Global FinTech Findexable (2020). Os Países Africanos de Língua Oficial Portuguesa estão atrás da maioria dos outros países da África subsariana neste índice. Entre estes países, Moçambique tem estado na vanguarda da inovação financeira móvel e online com um ecossistema regulador favorável. Angola ainda não tem nenhum serviço de moeda eletrónica a funcionar, mas existe um consenso crescente sobre a necessidade de se apoiar a introdução de serviços de FinTech disponíveis para telemóvel. Cabo Verde é o país Africano de língua portuguesa com o sistema financeiro mais desenvolvido. Paradoxalmente não há, no entanto, nenhum serviço de moeda eletrónica disponível no país, nem a formalização de iniciativas FinTech ligadas a sistemas de pagamentos.

O FinTech Report faz parte da FinTech Initiative da Social Equity Initiative, uma parceira entre a Nova SBE, o Banco BPI e a Fundação “la caixa” que visa impulsionar o setor social em Portugal com uma visão de longo prazo, traçando um retrato do setor social em Portugal e desenvolvendo programas de investigação e capacitação para apoiar organizações sociais.
