Credit ratings and government bonds evidence before, during and after the european debt crisis

Neste projeto, investigamos se as agências de rating e as taxas de juro de longo prazo da dívida soberana tiveram uma influência recíproca antes, durante e após a crise da dívida soberana Europeia. Esta análise é realizada, estimando a relação existente entre os ratings da dívida soberana ou taxas de juro e factores macroeconomicos e estruturais, através de uma diferente aplicação de metodologias utilizadas para este efeito. Os resultados obtidos demonstram que, no período da crise soberana, os ratings e as taxas de juros tiveram um mútuo impacto, sugerindo que as descidas dos ratings podem ter conduzido a profecias auto-realizáveis, levando países relativamente estáveis a um eventual incumprimento

Bank networks and firm credit: an agent based model approach

Starting from the idea that economic systems fall into complexity theory, where its many agents interact with each other without a central control and that these interactions are able to change the future behavior of the agents and the entire system, similar to a chaotic system we increase the model of Russo et al. (2014) to carry out three experiments focusing on the interaction between Banks and Firms in an artificial economy. The first experiment is relative to Relationship Banking where, according to the literature, the interaction over time between Banks and Firms are able to produce mutual benefits, mainly due to reduction of the information asymmetry between them. The following experiment is related to information heterogeneity in the credit market, where the larger the bank, the higher their visibility in the credit market, increasing the number of consult for new loans. Finally, the third experiment is about the effects on the credit market of the heterogeneity of prices that Firms faces in the goods market.

A comparative study of the credit card market dynamics in Mexico and Brazil

This research analyzes and compares the attractiveness of the Brazilian and Mexican credit card markets from a financial firm’s perspective. The market dynamics in Latin America’s two economic powerhouses are fleshed out with qualitative and quantitative data, using a strategic framework to structure the analysis. Since its adoption by both countries in 1956, credit card usage has experienced many years of double digit growth. However, penetration levels remain low compared with most developed countries. Brazil has a more developed credit card infrastructure, with more potential profit, and issuers might face fewer competitive challenges.  Alternatively, Mexico, is witnessing a more favorable economy, a friendlier business and regulatory environment, combined with fewer financial products that compete with the credit card. Therefore, this paper concludes that Brazil and Mexico both offer market opportunities for credit card companies that can navigate the different technological, demographic, macroeconomic, and regulatory shifts in each country.
