Estudos demonstram ganhos inesperados podem provocar a diminuição da aversão ao risco, um efeito conhecido por house money effect. Neste estudo, testa-se a hipótese de que algo semelhante poderá estar na origem do aumento do endividamento das famílias perante a política de devolução de rendimentos e diminuição da sua tributação seguida pelo atual governo socialista. Para mais, avança-se a hipótese de que o ambiente económico-financeiro favorável poderá potenciar este efeito. Para testar estas hipóteses, desenvolveu-se uma atividade experimental na qual os participantes fazem uma gestão de rendimentos e despesas ao longo de vários ciclos, ao longo dos quais são enfrentados por duas oportunidades de contração de crédito. Os resultados não suportam a hipótese de que o aumento de rendimentos poderá induzir o house money effect. No entanto, surgem evidências de que a aversão ao risco poderá diminuir em função da favorabilidade do ambiente económico-financeiro. Interpretações para estes resultados são avançadas, assim como sugestões para estudos futuros que permitam ultrapassar algumas limitações da presente investigação.
Studies show that windfall gains may induce low risk aversion, an effect know as house money effect. In the present study, it is tested the hypothesis that something similar may have originated the increase indebtedness of families in the context of the present socialist government’s policy of returning income and diminishing income taxation. Furthermore, it is proposed a hypothesis that the favourability of the economic and financial environment may increase this effect. To test these hypothesis, an experimental activity was developed in which participants had to manage income and expenses throughout several cycles, during which they had opportunities to get new credit. Results do not support the hypothesis that increasing income may induce the house money effect, although there is evidence that risk aversion may be reduced due to the favourability of the economic and financial environment. Interpretations for these results are presented, as well as suggestions for future studies that may overcome the limitations of the present one.
