Let's narrow the focus a bit, and use capital to mean the cash (and equivalent) assets of a commercial enterprise.
- assets available for use in the production of further assets
- wealth in the form of money or property owned by a person or business and human resources of economic value
The question then is: What can the enterprise do with it's capital. I see two possibilities: distribution and use.
a) Payment, as salaries, wages, bonuses, etc.
b) Payment as dividends
c) Donations - charitable or political
e) Bribes (let's be both complete and realistic)
a) Investment - here, narrowly defined as spending on:
i Property (for facility use)
ii Physical plant
iv Employee training
b) Rent seeking
ii Interest bearing notes
iii Speculative Ventures (Financial tail chasing)
iv Mergers and Acquisitions
c) Reduce liabilities (H/T to Angry Saver in comments)
d) Hoarding (H/T to Stagflationary Mark in comments)
That's all I can come up with. Help me out here. Am I on the right track? What did I miss?
