1. Important Details

2. Debt and Equity To start a firm requires $ for plant, equipment, product development, etc Those $ will be part (or all) of fixed costs Can raise the $ two ways: – Borrow at fixed rate of interest– Debt – Sell shares in the firm - Equity

3. Opportunity Cost The value of the item in the best use (other than this one.) – Value of my grandma’s building if not used for my Dad’s company – Value of my Dad’s time if not used for his company – Value of the money invested in the business if it were used in another business instead.

4. Profit and Earnings Economic profit: Revenue – All costs – Cost Includes: all of the money that went in to the firm, whether debt or equity Opportunity cost of entrepreneurs’ labor, real estate etc. Earnings: Revenue – VC – debt service – Doesn’t acct for Opportunity cost Value of invested capital (what people paid for shares.)

5. Businessman and Economist Business: I got earnings of $100K on my $1M investment. I earned 10 percent! Economist: He earned the same 10 percent on his money that he would have earned if he just invested in the stock market. – So: Earnings – Opportunity Cost of Capital = ZERO – His profits were ZERO. (Just terminology, but important.)

6. Bankruptcy Earnings < 0 Lets assume no self supplied labor, buildings,etc Same as Revenues – VC – debt service < 0 Same as R – VC – debt – opp. Cost capital < - opp. Cost of capital Same as Profit < Opp. Cost of Capital Can’t pay bank loans and VC of production.

7. Point of Bankruptcy Legal mechanism Allows firm to negotiate with suppliers and pay back less than all its debt so that it can survive. Makes sense when can pay back some, but not all of debt. Makes sense when firm will make more money alive than dead
