As Steve's suggestion, i found a dictionary connected to my subject: Business economics. To buy a heavy dictionary is not convenience to bring anywhere i need to look up so that i found it on internet like Cambridge Dictionary Online which i often use for academic purpose.
Here is my dictionary:

Oxford dictionary of business ( book on amazon)
Economic Dictionary Online:

Dictionary 2
