Este estudo utiliza dados do Survey of Consumer Finances (SGF) de 2007 e 2013 para examinar a propensão à poupança das famílias americanas no período de pré e pós-crise econômica, baseando-se no modelo de dois períodos de consumo/poupança de Bowman, Minehart e Rabin (1999). Esse modelo assume existência de assimetria no comportamento de poupança dos agentes em resposta a choques positivos e negativos na renda. Os resultados obtidos via modelos logit sugerem que a crise tenha aumentado a relevância de fatores como número de filhos, idade, grau de instrução, renda e incerteza econômica; enquanto patrimônio, tolerância a risco financeiro, horizonte de investimento, saúde e possuir casa própria foram fatores que perderam relevância. As evidências sugerem que eventos da magnitude da crise de 2008 podem ocasionar mudanças no comportamento financeiro dos agentes, as quais são inteiramente explicadas pelos choques financeiros.

This study used data from the Survey of Consumer Finances (SGF) for 2007 and 2013 in order to examine the propensity to savings of American households in the pre- and post-economic crisis, based on the two-period consumption/savings model by Bowman, Minehart and Rabin (1999). This model assumes there is an asymmetry in agents' savings behavior in response to positive and negative shocks in the income. The results obtained by logistic regression suggest that economic crisis has increased the relevance of factors such as number of children, age, education level, income and economic uncertainty, while equity, financial risk tolerance, investment horizon, health and home ownership were factors that lost relevance. The evidence suggests that events with the magnitude of the 2008 crisis may lead to changes in the financial behavior of agents who are not entirely explained by the financial impacts suffered.

El estudio utiliza datos del Survey of Consumer Finances (SGF) del 2007 y el 2012 para analizar la propensión al ahorro de las familias americanas en el periodo pre y post crisis económica. Se basa en el modelo de dos períodos de consumo/ahorro de Bowman, Minehart y Rabin (1999), el que asume existencia de asimetría en la conducta de ahorrar de los actores en respuesta a choques positivos y negativos en los ingresos. Los resultados obtenidos vía modelos logit sugieren que la crisis haya aumentado la relevancia de factores como número de hijos, edad, escolaridad, ingresos e incertidumbre económica; mientras que patrimonio, tolerancia a riesgo financiero, plan de inversión, salud y vivienda propia fueran factores que perdieron relevancia. Las evidencias sugieren que eventos de la magnitud de la crisis del 2008 pueden ocasionar cambios en el comportamiento financiero de los agentes, los que son completamente explicados por los choques financieros.
