The determinants of net interest margins & net interest spreads in the Russian & Japanese Commercial Banking sectors

This study presents an empirical investigation of the determinants of net interest margins and spreads in the Russian and Japanese banking sectors with a particular focus on commercial banks. Net interest mar-gins and spreads serve as indicators of financial intermediation efficiency. This paper employed a bank-level unbalanced panel dataset prolonging from 2005 to 2014. My main empirical results show that bank characteristics explain the most of the variation in not only net interest margins but also in spreads. Capi-talization, liquidity risk, inflation, economic growth, private and government debt are important determi-nants of margin in Russia. In Japan to the contrary loan and deposit market concentration along with bank size do predominate. Common significant variables in both countries are the substitution effect, cost effi-ciency and profitability. Turning to net interest spreads, micro- and macro-specific variables are the main significant drivers in Russia. I reach the conclusion that there are no significant determinants of net interest spreads in Japan within the original selection of variables, but operating efficiency and deposits to total funding seem to prevail. In both countries, there are solid differences in the net interest margins as well as spreads once the pre- and the post-crisis periods are considered.

Método de ensino de português para falantes de russo: proposta de materiais didáticos bilingues

Após breve observação da história do desenvolvimento das relações entre Portugal e a Rússia e da situação atual do ensino do português Língua Estrangeira, na Federação Russa, incluindo os programas, metodologias, estratégias, materiais didáticos feitos na Rússia, procede-se a uma análise das dificuldades que têm os falantes de russo, as causas e fontes das complicações mais recorrentes tendo em conta os erros mais típicos dos falantes de russo na aprendizagem de língua portuguesa. Centraremos o nosso trabalho na produção de uma sequência didática que corresponda às necessidades do destinatário que tem como língua nativa o russo.
