O objetivo deste trabalho é Identificar os fatores macroeconômicos e os indicadores industriais que influenciaram o spread bancário brasileiro no período de Março de 2011 a Março de 2015. É considerada a subclassificação de alguns segmentos de atividade industrial. Foram utilizados dados mensais de séries temporais em modelos de regressão linear multivariada com uso do Eviews (7.0), dezoito variáveis foram consideradas como possíveis determinantes.. Influenciam positivamente; a inadimplência, os IPIs (Índices de Produção Industrial) de bens de capital, bens intermediários, bens de consumo duráveis, bens semiduráveis e não duráveis, a Selic, o PIB, a taxa de desemprego e o EMBI+. Determinam negativamente; os IPIs bens de consumo e geral, IPCA, o saldo da carteira de crédito e o índice de vendas no varejo. Foi considerado p-valor de 05%.. A conclusão principal é que o progresso da indústria, da geração de empregos e do consumo podem reduzir o spread.
Central Bank Digital Currency (CBDC) can be defined as a virtual currency based on node network and digital encryption algorithm issued by a country which has a legal credit protection. CBDCs are supported by Distributed Ledger Technologies (DLTs), and they may allow a universal means of payments for the digital era. There are many ways to proceed, they all require central banks to develop technological expertise. Considering these points, it is important to understand the new IT governance in the financial markets due to CBDC and digital economy. Information Technology is an essential driver that will allow the new financial industry design. This paper has the objective to answer two questions through an updated Systematic Literature Review (SLR). The first question is What IT resources and tools have been considered or applied to set the governance of CBDC adoption? The second; Identify IT governance models in the financial market due to CBDC adoption. Bank for International Settlements (BIS) publications, Scopus and Web of Science were considered as sources of studies. After the strings and including criteria were applied, fourteen papers were analyzed. This paper finds many IT resources used in the CBDC adoption and some preliminary IT design related to the IT governance of CBDC, in the results and discussion section the findings are more detailed. Finally, limitations and future work are considered.
Cryptocurrency can be understood as a digital asset transacted among participants in the crypto economy. Every cryptocurrency must have an associated Blockchain. Blockchain is a Distributed Ledger Technology (DLT) which supports cryptocurrencies, this may be considered as the most promising disruptive technology in the industry 4.0 context. Decentralized finance (DeFi) is a Blockchain-based financial infrastructure, the term generally refers to an open, permissionless, and highly interoperable protocol stack built on public smart contract platforms, such as the Ethereum Blockchain. It replicates existing financial services in a more open and transparent way. DeFi does not rely on intermediaries and centralized institutions. Instead, it is based on open protocols and decentralized applications (Dapps). Considering that there are many digital coins, stablecoins and central bank digital currencies (CBDCs), these currencies should interact among each other sometime. For this interaction the Information Technology elements play an important whole as enablers and IT strategic alignment. This paper considers the strategic alignment model proposed by Venkatraman (1993) andLuftman (1996). This paper seeks to answer two main questions 1) What are the common IT elements in the DeFi? And 2) How the elements connect to the IT strategic alignment in DeFi? Through a Systematic Literature Review (SLR). Results point out that there are many IT elements already mentioned by literature, however there is a lack in the literature about the connection between IT elements and IT strategic alignment in a Decentralized Finance (DeFi) architectural network. After final considerations, limitations and future research agenda are presented.
