Previous issue date: 2018-04-17 / O presente trabalho consiste em uma análise do consumo das famílias utilizando-se a hipótese da renda permanente e do ciclo de vida, com base nos indicadores de consumo, crédito, renda e juros no Brasil durante o período de 2003 a 2017, em um ambiente econômico que apresentou um ciclo de expansão, seguido por duas crises econômicas, sendo que a segunda crise (após 2015) trouxe agravamentos ao ambiente econômico do país. Para tanto, utilizaram-se a metodologia proposta por Campbell e Mankiw (1989) e o Vetor Auto Regressivo (VAR) sobre as séries históricas de renda, crédito, taxa de juros e volume de crédito à pessoa física. Com base na metodologia de Markov Switching-VAR, buscou-se analisar quebras estruturais no comportamento do consumidor no período analisado. O resultado mostrou duas quebras estruturais, uma entre o segundo trimestre de 2003 e o quarto trimestre de 2007 e outra entre o primeiro trimestre de 2008 e o segundo trimestre de 2015. Em todos os períodos, o modelo de Campbell e Mankiw apresentou comportamentos similares, nos quais se rejeita a hipótese da renda permanente. No período entre o terceiro trimestre de 2015 e o terceiro trimestre de 2017, momento de grande impacto da crise econômica brasileira, obteve-se uma rejeição da hipótese da renda permanente com aumento significativo da restrição à liquidez e ao crédito. Segundo o modelo VAR, que tenta identificar o comportamento dinâmico das variáveis em estudo, observou-se que choques gerados individualmente na renda e no crédito têm impacto positivo no consumo, ou seja, geram um incremento no consumo das famílias; no entanto um choque nos juros tem um efeito inversamente proporcional no consumo, o que está de acordo com a rejeição da hipótese da renda permanente. / The present work consists of an analysis of household consumption using the permanent income and life cycle hypothesis, based on consumption, credit, income and interest rate indicators in Brazil from 2003 to 2017, in an economic environment that presented a cycle of expansion, followed by two economic crisis, with the second crisis (after 2015) aggravating to the country's economic environment. In this work the employed methodology was the one proposed by Campbell and Mankiw (1989) together with the Vector Auto Regressive (VAR), on the historical series of income, credit, interest rate and volume of credit to individuals. Based on the Markov SwitchingVAR methodology, we sought to analyze structural breaks in consumer behavior during the analyzed period. The result showed two structural breaks, one between the second quarter of 2003 and the fourth quarter of 2007, and another between the first quarter of 2008 and the second quarter of 2015. In all periods, the Campbell and Mankiw model showed similar behavior, in which we reject the hypothesis of permanent income. Between the third quarter of 2015 and the third quarter of 2017, a period of great impact of the Brazilian economic crisis, the hypothesis of permanent income was rejected, with a significant increase in the restriction on liquidity and credit. According to the VAR model, which tries to identify the dynamic behavior of the variables under study, we have observed that shocks individually generated on income and credit have a positive impact on consumption, ie, it generates an increase in household consumption. On the other hand, a shock on the interest rate causes an inversely proportional effect on consumption, which is in line with the rejection of the hypothesis of permanent income.
