What financial models would be most effective to write about for an MBA admission essay?
I am currently applying to several graduate schools (MBA programs) in NY and NJ. If you can provide me with what topics specifically what areas of finance and marketing are the most desirable to learn about I will choose you as the best answer ASAP. Please provide several models, examples etc. Thanks

Write about yourself. Tell how you go about research, via companies, countries, or commodities. Show how you yourself is a viable agent for making a profit based on your decision making process and market execution. Become the boss, leader, and broker. Then sell the character.
Topics of Finance: Stocks – T-Bills – Commodities – Index Funds
Topics of Marketing: CEO’s – Political Leaders – Brokerage Houses – Storage Facilities
