Curva de Demanda, Curva de Oferta, Bem de Giffen, Teoria do ConsumidorResumo
A demanda por um bem de Giffen é atípica, isto é, cresce conforme o preço aumenta. A representação tradicional desse fenômeno é uma curva de demanda com inclinação ascendente. O modelo é muito problemático, pois implica que a demanda pode oscilar entre o infinito e um infinito negativo. Um cenário, no mínimo, irrealista. Nesse artigo, discutimos brevemente os problemas do modelo tradicional, propondo um melhor: a curva Z. Como os bens de Giffen são uma consequência de uma redução na renda do consumidor, a curva Z ilustra os efeitos dessa mudança sobre a riqueza. Nosso objetivo aqui não é descartar totalmente a construção mental dos bens de Giffen. Em vez disso, propomos o que acreditamos ser um método mais preciso de representação gráfica dos bens de Giffen.
