Hello Rocio, I would love to teach you some English if you will teach me some Spanish.

You would say "Economic product" and 'Economic Products". The use of the ending -al is when you use "economic" as a verb, or to describe something. Example: a small, economical car. The word, economic, is used as a noun, or an physical thing. Example: The economic backlash led to a decline in the nations security.
