Endividamento Antes e Após a Introdução do Euro

Análise ARDL do caso português
Authors: Gaspar, Catarina da Conceição de Pinho;

Endividamento Antes e Após a Introdução do Euro

Abstract

Em resultado da passagem para estabilidade monetária, analisamos a taxa de esforço real com o serviço de dívida para Portugal num contexto de diminuição das taxas de juro nominais. Os dados utilizados são mensais e cobrem o período de Janeiro de 1991 a Setembro de 2013. Foi aplicado o UECM do modelo ARDL que permitiu capturar os efeitos de curto-prazo e longo-prazo. Os resultados revelam que a realidade portuguesa tem dois comportamentos distintos, um antes e outro depois da efetivação da união monetária. Detetamos a presença de diferentes variáveis na explicação do nível de endividamento, para cada um dos períodos. No primeiro período (1991M1-1998M12) apenas a variável esforço financeiro é relevante na explicação do nível de endividamento dos agentes económicos. No segundo período (1999M1-2013M9) a variável profundidade financeira, balança de pagamentos da Alemanha e saldo conjunto da balança corrente e de capital também se revelaram estatisticamente significantes no aumento do nível de endividamento. A investigação suporta para o primeiro período, que o aumento do esforço financeiro reduz o nível de endividamento dos agentes económicos. No segundo modelo, estamos perante a presença de um choque estrutural, resultado da mudança de regime que ocorreu na economia. Neste período, para uma diminuição do esforço financeiro ocorre uma diminuição do nível de endividamento, no longo-prazo. Os resultados suportam a existência de uma mudança de regime que ocorreu por volta de 1999, cuja natureza económica produziu um impacto de tal magnitude que originou a mudança de endividamento, no antes e após a introdução do euro. Para o segundo período (1999M1-2013M9) concluiu-se sobre a presença de cointegração entre o esforço financeiro e o endividamento.

As a result of the transition to monetary stability, we analyzed the real effort rate with the debt service for Portugal in a context of a decrease in nominal interest rates. Monthly time series data from January 1991 to September 2013 were used. The UECM of the ARDL model was applied which allowed capturing the long-run and short-run effects. The results suggest that the Portuguese reality has two distinct behaviors, one before and one after effecting monetary union. We detected the presence of different variables in explaining the level of indebtedness in both periods. In the first period (1991M1- 1998M12), only financial effort is relevant when explaining the level of indebtedness of the economic agents. In the second period (1999M1-2013M9) the financial depth, German balance of payments and current balance and capital account are also statistically significant in the increase of the indebtedness level. The research supports that in the first period, the increase of financial effort reduces the level of indebtedness of the economic agents. In the second period, we have the presence of a structural break, resulting from the regime change that occurred in the economy. In this period, for a decrease of financial effort there is a reduction of the indebtedness level, in the long-run. The results support that there is a regime shift around 1999, whose economic nature produced an economic impact that caused indebtedness change, before and after euro introduction. For the second period (1999M1-2013M9) we obtained a cointegration relationship between financial effort and indebtedness.
