A business becomes real when you legally register its formal structure. Registering provides legal and financial protection, liability separation, and access to necessary licenses, permits, and tax structures.
Owned by one person with no legal separation from the business.
Pros: Simple setup, pass-through taxation (profits go directly to the owner’s personal taxes).
Cons: Owner is personally liable for debts and lawsuits, limited funding options, and difficulty securing loans.
General Partnership (GP):Â Equal personal liability and decision-making among partners.
Limited Partnership (LP):Â One partner has unlimited liability, others have limited liability.
Limited Liability Partnership (LLP): All partners have some liability protection, but less than corporations.
đź’°Â LPs & LLPs require more legal and accounting work, making them costlier than sole proprietorships.
C-Corp (Corporation)
Separate legal entity from owners.
Pros:Â Limited liability, easier funding via public stock sales.
Cons: Double taxation (profits taxed at the corporate level and again as personal income for stockholders).
Examples:Â eBay, Airbnb.
B-Corp (Benefit Corporation)
Focuses on social impact alongside profit.
Pros:Â Limited liability, protection for CEOs making social-impact decisions.
Cons:Â Taxed the same as C-Corps.
Examples: Patagonia, Ben & Jerry’s.
Hybrid of a corporation and partnership.
Pros:Â Liability protection, pass-through taxation, easier for startups.
Cons: If an owner leaves/joins, the LLC may need to be restructured.
Owned by its members (users/customers).
Pros:Â Limited liability, stockholders vote on business decisions.
Cons:Â Slower decision-making, harder to get traditional bank loans.
Examples:Â REI, farming co-ops.
For charitable, educational, religious, or scientific work.
Pros:Â Tax-exempt, eligible for grants.
Cons:Â Cannot distribute profits to owners or shareholders.
Liability:Â Legal responsibility for business debts and lawsuits.
Pass-through taxation: Business profits go directly to owners’ personal income taxes (used by Sole Proprietorships, Partnerships, LLCs).
Double taxation: Corporations pay taxes on profits before distributing dividends, and stockholders pay taxes again on received income.
Impact Investing:Â Investors fund businesses for social/environmental benefits rather than pure profit.

https://corporatefinanceinstitute.com/resources/economics/market-structure/
Perfect competition
Imagine you have a vibrant Farmers market where dozens of vendors are selling identical apples
Many buyers and sellers exist, and no single vendor can set the prices
If a single vendor or buyer changes their prices/demand, the market isn’t impacted
This market relies on supply and demand
3 key features:
Homogeneous products: the products are absolutely identical, theres no differentiation between one vendors products and another
Many buyers and sellers: no buyer or seller can influence the market price
Free entry and exit: firms can easily enter or exit the market and there aren’t really any steep barriers to entry
Real life examples:
Agricultural products: markets for staple crops like wheat or corn
Stock markets: stocks or companies can exhibit characteristics of the perfect competition
Fish markets: have multiple vendors selling the same exact type of fish
Monopolistic competition
Imagine a neighborhood filled with coffee shops, each offering unique blends and atmospheres
Key feature:
Differentiated products: each firm offers a product that is slightly different from another firm
Many sellers: numerous firms or sellers exist but they compete based on their brand and their quality because their goods are technically different
Free entry and exit: there are no barriers which mean new firms are allowed to enter the market
Real life examples:
Fast food chains: all serve burgers and similar things, but differentiate through branding and unique branding items
Clothing stores: Gap, H&M, and Old navy all sell clothes but they are unique based on their styles and pricing
Local restaurants: each one offers the same mean like pizza, but have different variations of the product
Oligopolies
Imagine an airline industry where just a handful of carriers control most of the market.
A small number of firms dominate, leading to strategic interactions among them when it comes to pricing strategies.
Key features:
Very few sellers: theres only a few dominant firms, so a limited number of companies hold significant market share in an industry.
Interdependence: each firm’s pricing and output decisions depend on their competitors, all must communicate with each other to know the optimal settings
Potential for Collusion: firms may work together to set prices or to limit output so they can keep their margins and profits high
Real life examples:
Airlines: AA, Delta, control the market and respond to their individual pricing
Satellites
Monopolies
Imagine your local water utility as the only provider in the area
One company controls the entire market, often due to high barriers of entry that prevent others from entering the market
Barriers: being too expensive, not having proprietary technology or licensing
Key features:
One seller: one firm dominates the market
Unique Product: theres absolutely no close substitutes available in the market
High Barriers to Entry: there’s significant obstacles that prevent competition from being introduces to this monopoly
Real life examples:
utilities
local cable providers: only Comcast available in certain places
Patented products like patented pharmaceuticals

Publicly traded company: A corporation whose ownership is dispersed among the general public through shares of stock that are traded through the stock exchange
Private company: owned by a relatively small number of shareholders, typically the company’s founders, management, or a group of private investors, like venture capital firms
shares aren’t available to the general public and aren’t traded on public exchanges
Difference between the two: how much financial information they are required to disclose
Public: must register with the SEC, file quarterly earnings reports, and provide other important information to shareholders and the public
These regulations are intended to protect the public and help them make informed investing decisions
Private: aren’t required to disclose financial information until they exceed a certain number of shareholders, then they have to register with the SEC
company leadership has more control and is less beholden to shareholders
Initial Public offering (IPO) - the way private companies choose to become publicly traded, public can go back to private
💡 Definition: A corporation whose ownership is distributed among the general public through shares of stock traded on the stock exchange (e.g., NYSE, Nasdaq).
