pardon me if i'm wrong here... but to me i think psychology = sociology...at least in economics..
some example on human psychology.
when bad news come out, people has
fear and they will not go out and buy stuff... and will not make any investment. so demand goes down. while shop owners see demand down, they
worry their business cannot tahan so they lower their price down. while those ppl who has
greed will say since the stuff so cheap now... i go borong a lot la.. when economy better i sell out all again at higher price. just some example of behavioral economics rite.. which palys major part in economics IMHO.
I think it's time to be more specific about what the '=' means. In my opinion, although sociology and psychology are quite similar, they have quite a number of differences, even within economic topics.

The difference is in the scope of study. One deals with the intrapersonal relation and the other deals with interpersonal relations. A lot of things you have described there is more interpersonal, so it's more sociology.
