I highly recommend applying to the US for you. Given your interests schools like Columbia, Wharton, Yale, Harvard, Princeton and MIT will just be so exciting for your economics passion. Williams, Swarthmore, UC-Berkeley are also great ones. I was able to graduate in 3 years at Harvard with a Bachelors and Masters Degree in Applied Math-Economics (Quantitative Econonomics) and relished in the flexibility of the program which let me delve deeply into behavioral economics, behavioral finance, econometrics and quantitative finance at my own pace.

The articles below are fairly nitty, gritty but introduce you to some of core landmark papers in behavioral finance and asset pricing. The books are much more approachable - my favorite was Jeffrey Sachs - Economics of a Crowded Planet. For the economists, I recommend reading their wikipedia pages, feeling inspired and then searching them on Google Scholar and reading some of their work.
