Unit 7: Production and Costs

Lesson 7.1: Types of Business Organization

This section introduces the foundational concepts of business organization in microeconomics, focusing on sources of capital, types of for-profit business structures, and profit calculation methods.

Sources of Capital

• Capital refers to financial resources used by businesses to purchase physical assets for production.

• Businesses can obtain investment funds in two main ways:

  • Debt Financing: Includes loans, mortgages, bonds, lines of credit, etc. Debt must be repaid with interest.

  • Equity Financing: Involves selling stock or shares. Investors contribute money in exchange for ownership; this money does not need to be repaid, but investors expect returns.

• Interest is paid on all loans, and equity investors expect a share of profits over time.

Types of For-Profit Business Organization

• Sole Proprietorship:

  • Owned and managed by a single person.

  • Owner is personally responsible for all assets and liabilities.

  • Easy to establish with minimal legal requirements.

  • Profits flow directly to the owner and are taxed once at the owner's income rate.

  • Disadvantages: Limited financing options and personal liability for debts.

• Partnership:

  • Owned by more than one person, managed by one or more partners.

  • Partners may be personally responsible for assets and liabilities (except in limited partnerships).

  • Greater availability of equity financing and easier borrowing.

  • Profits are taxed once at the partners' income rate.

  • Disadvantages: Financing limited to partners' contributions; personal liability for debts.

• Corporation:

  • Legally distinct from its owners, managed by directors and professional managers.

  • Owners are not responsible for business assets or liabilities.

  • Greater availability of equity financing and easier debt financing.

  • Disadvantages: Complex legal requirements and separate corporate tax system.

Expected Return and Profit Maximization

The primary goal of for-profit businesses is to maximize profit. The expected profit depends on the amount of capital invested and the success of the business venture.

• Profit comparisons across investments are made using the expected rate of return, which is the percentage of capital invested.

Calculating Profits

Accounting Profits

• Calculated based on input costs only.

• Appear on financial statements and are used for tax purposes.

Economic Profits

• Reflect the risk-adjusted expected return, accounting for the opportunity cost of capital.

• Used for investment decisions and project appraisal.

• This is the profit concept most relevant for microeconomic analysis.

Formula for Economic Profit

• Economic Profit () is calculated as:

Expanded:

• Revenue: Total income from quantity sold.

• Input Costs: Expenses for labour, materials, utilities, etc.

• Expected Accounting Profit:

Example

• If a firm sells 100 units at $10 each, with input costs of $500 and an expected rate of return of 5% on $1000 capital:

Additional info: Economic profit is a more comprehensive measure than accounting profit, as it considers opportunity costs and is crucial for evaluating business decisions in microeconomics.
