I believe strongly that women are strongly made of conservative mentality, it is therefore pertinent to say that, women are more economical than men. Before a delve into responsibilities is natural construct, men are wired to have the consciousness of being responsible of loads of stuff and that is directly reflected in their expenditure. On the other hand, a woman is not legally obliged to be in charge of basic fundamentals, at least, before we consider people and cultures welcoming 50/50 bill splitting.
