Microsoft Word is pervasively used to write ordinary documents and academic papers, because it is easy to operate and you will see what you will get. But if you are going to deal with much more sophisticated mathematical equations, LaTex may become a better choice. But with LaTex, you cannot simply get what you see (maybe sometimes if you want to insert, say, a table, it would be difficult for you to define the specific attributes of the table unless you become very experienced).
What if we combine the merits of Word and LaTex? Then here comes Lyx (also see here). Most of the time, the quasiconcavity of preference relations will hold.
So is it the time to dump Word??
