Functions of Financial Markets

Price Determination

• When a company has assets listed in a financial market, it can determine their worth.
• Investors can ascertain the value of their investments.
• Markets offer liquidity for investors' assets.

Financial Assets Characteristics

Liquidity

Ease with which an asset can be converted into cash.

Return and Liquidity Relationship

• If an asset is very liquid, the return asked by investors is very low.
• When assets are less liquid, investors demand higher returns.

Risk

The probability of not recovering the principal or the coupons.

Rating agencies analyze the risk associated with issuers.

Types of Financial Markets

Primary Markets

These markets facilitate the issuance of new securities. Investors pay for the assets to the... Continue reading "Financial Markets: Functions, Assets, and Indexes Explained" »

Business Plan vs. Business Model

A Business Plan is a detailed document (typically 50-100 pages) containing extensive financial projections and loan projections. In contrast, a Business Model is a much less detailed, single concept that describes the specific way a business expects to make money. It illustrates the capabilities and resources required to create, market, and deliver value while generating profitable, sustainable revenue streams.

Common Business Archetypes

Key business archetypes include:

• Entrepreneur
• Manufacturer
• Wholesaler
• Inventor
• Contractor
• Financial Trader

Four Key Aspects of a Business Model

The four pillars of a business model are:

1. Offer
2. Customer
3. Infrastructure
4. Finance (including revenue streams and cost structure)

Scalability in Modern

Cost-Volume-Profit (CVP) Analysis Formulas

Contribution Margin Calculations

• Contribution Margin (CM) per Unit: $P - VC$ (Price minus Variable Cost)
• Total Contribution Margin (TCM): $(P \times Q) - (VC \times Q)$
• CM Ratio: Unit CM / Unit Selling Price
• Variable Expense (VE) Ratio: Unit VE / Unit Selling Price

Break-Even Point (BEP) Determination

1. BEP Equation Method

• Profits: (Sales - Variable Expenses) - Fixed Expenses
• Sales at BEP: Variable Expenses + Fixed Expenses + Profits (where Profits = 0)

2. Contribution Margin Method

• BEP in Units: Fixed Expenses / Unit CM
• BEP in Total Sales Dollars: Fixed Expenses / CM Ratio

Target Profit Calculations (Contribution Margin Approach)

• Unit Sales to Attain Target Profit: (Fixed Expenses + Target Income) / Unit CM
• Dollar

Financial Analysis Techniques

Sensitivity Analysis

• Considers changes in variables, only one change in each simulation.
• Provides a tool to answer “what if” questions.
• By comparing changes in different variables, we can assess project risks and make decisions accordingly.

Scenario Analysis

• Considers changes in two or more variables simultaneously.
• Allows consideration of the best and worst-case scenarios.
• Requires a large number of simulations.
• By comparing different scenarios, we can assess project risks.

Break-Even Analysis

• The Break-Even point is the level of sales that offsets all costs.
• It can be calculated in terms of profit or cash flow.
• It must assume a certain sales mix if the product contributions are different.

Monte Carlo Simulation

• Statistical

High Hourly Wage Rate

High hourly wage rate: Workers are paid according to the amount of hours they work. A "high" hourly wage means being paid a significant amount of money per hour.

Piece Rate Element

Piece Rate Element:

• Employees: The amount they earn is directly associated with their effort, encouraging them to produce more efficiently. However, it may not be convenient for workers who prioritize quality over quantity.
• Employer: More production potentially leads to increased profits. However, workers who rush might compromise quality.

Responsibility and Motivation

Responsibility motivates workers: Giving employees responsibility can create a sense of importance, making them feel appreciated and valuable. However, some workers may find responsibility... Continue reading "Understanding Business Concepts and Strategies" »

OLIGOPOLY

A market structure characterized by a small number of sellers, each offering products that are similar or identical to those of their competitors. Examples of oligopolistic industries include chocolate bars, brewing, banking, oil, and supermarkets.

CONCENTRATION RATIO

The proportion of the total market share held by the top firms in an industry. For instance, a five-firm concentration ratio of 80% indicates that five companies control 80% of the market share.

GAME THEORY

The study of how individuals make decisions in strategic situations, considering the potential responses of others to their actions. Game theory is crucial for understanding oligopolies, as firms in these markets must act strategically due to the limited number of competitors....

Central Banks and Shadow Banking

Competencies of Central Banks

• Monetary Policy (open market operations)
• Exchange Policy
• Lender of Last Resort
  • Bank of Banks
  • Bank of the State (In the US but not in Europe)
• Supervision of the Financial System

Banks create credit, money, and thus purchasing power. The ability to create credit and purchasing power, for good or ill purposes, is not unique to banks.

Shadow banking activities can create credit and money equivalents outside the normal banking sector. Central banks have not been able to counter the unsustainable shadow banking boom and have lost the capacity to control the quantity of money.

History of the Spanish Financial System

The modern history of Spanish banking begins in 1856. The Parliament approved two... Continue reading "Central Banks, Shadow Banking, and Spanish Financial History" »
