These types of economies are usually found in countrie like Asia, South America and Africa. These people harvest their own crops on their own land.

This is sort of like a "democratic" economy. You can choose to where anywhere you like as long as there is a job opening. You can open your own business and run it. You may do extremely well with your business but if it is not popular with the public, you will not be in business for long.

Investment Strategy

I did not have a strategy when I began to invest and I should have because my stocks are not doing well. I have only invest in 3 stocks but I plant to buy maybe 2 or 3 more. I want to find a smaller company to invest in because as Mr.Moloney said they are more likely to change and make money.

Investments

I want to invest in Citigroup, BP, Walt Disney, Yahoo and Google.
