I busted my brains with it, I was sure it had something to do with a package. Writing papers in LaTeX can really make a student feel like an "experienced" economist
Just yesterday I started using LaTeX to write an article on economics. Although I have read in the lshort document I have a problem with the ">" sign. If I type ">" I get "¿" (an inverted question mark) and if I type "<" I get "¡" (an inverted exclamation mark).
