Freight Transportation Fundamentals

Importance of an Effective Transportation System

• Greater competition
• Economic Scale
• Reduced price

Service Choices and Their Characteristics

• Price
• Transit time and variability
• Loss and damage

Transportation Rate Profile

1. Volume related rates
2. Distance-related rates
   • Uniform rates
   • Proportional rates
   • Tapering rates
   • Blanket rates: meet the rates of competitors
3. Demand-related rates: Transportation rate is set by competitor

Transportation Charges

• Line-haul rate
  • By products
  • By shipment size
  • By route
  • Miscellaneous rates
• Special service

Line-Haul Rates

1. By products
   • Classification system was devised (T 6.4)
   • Class rates: once a product has a freight classification, line-haul charges can be determined. Zip codes are used for the location (T 6.5)
   • Break

Scarcity

The limited nature of society’s resources.

Economics

The study of how society manages its scarce resources.

Efficiency

The property of society getting the most it can from its scarce resources.

Equity

The property of distributing economic prosperity fairly among the members of society.

Opportunity Cost

Whatever must be given up to obtain an item.

Marginal Changes

Small, incremental adjustments to a plan of action.

Market Economy

An economy that allocates resources through the decentralized decisions of many firms and households as they interact in markets for goods and services.

Market Failure

A situation in which a market, left on its own, fails to allocate resources efficiently.

Externality

The uncompensated impact of one person’s actions on...

Financial Ratio Analysis

Financial Ratios: What Are They?

• A value based on common financial metrics.
• The result of dividing one financial statement item by another, facilitating interpretation and comparison.

Liquidity Ratios

Ability to meet short-term obligations.

Current Ratio = Current Assets / Current Liabilities

Measure: Ability to pay short-term debts.

Interpretation: The higher the ratio, the better the liquidity position, although it may represent some short-term debt or excess assets.

Quick Ratio = (Current Assets - Inventory) / Current Liabilities

Measure: Ability to pay quickly in the short term.

Interpretation: The higher the ratio, the better the liquidity position, although it may represent some short-term borrowing or excess assets.

Understanding GDP Variation

When calculating Gross Domestic Product (GDP) as price multiplied by quantity, its variation may be due to a change in prices or a change in quantities. When comparing the GDP of several periods, we are generally not interested in the variation due to prices. This is when we speak of Real GDP. Real GDP is calculated using the output of the year in question and the prices of a base year used as reference. If we do not do this and instead use the prices of the year in question, then we get what we call Nominal GDP.

Who Contributes to GDP?

Economists divide GDP into four broad categories, each corresponding to different types of buyers represented in GDP:

1. Consumption Expenditure (C): Purchases by consumers.
2. Private Investment

Historical Context of Employer-Employee Relations

The relationship between employers and employees was historically based on the free will of the parties to close a deal. Workers, needing their jobs to live, often endured inhumane conditions and accepted high mortality rates. This led to the appearance of syndicates (unions) demanding better social and economic conditions. Notably, in the nineteenth century, unions were often illegal.

Economic Fundamentals: Revenue and Income

Revenues result from successfully marketing goods and services. Factors of production operate in complement, exchanging resources.

Defining Income

Income is the value or price of a productive resource over a specific time period. Income depends on the factor of production:

• Wages:

Understanding Market Fundamentals

A market is a group of buyers and sellers of a good or service. The terms supply and demand apply to the conduct of individuals in their interaction with others in the markets:

• Buyers determine demand.
• Sellers determine supply.

Types of Competitive Markets

A competitive market is one in which there are many buyers and sellers, so neither party can independently affect the price.

• Perfect Competition: Features homogeneous products and many buyers and sellers. Participants are price-takers.
• Monopoly: A single seller who sets the price.
• Oligopoly: A market with few sellers who are not always aggressive competitors.
• Monopolistic Competition: Many sellers offering differentiated products, allowing each to set their own price.

Financial Ratio Formulas

Current Index: Current Assets / Current Liabilities

Quick Index (Acid Test): (Circulating Active Assets - Inventory) / Current Liabilities

Indebtedness Index: Total Liabilities / Total Assets

Long-term Debt on Assets: Long-term Debt / (Long-term Debt + Equity)

Interest Expense Coverage: (Mean Earnings (ISLR) + Interest Expense) / Interest Expense

Debt Payment Coverage: (ISLR + Earnings After Depreciation) / Long-term Payment

Activity and Profitability Indices

Inventory Turnover: (Amount of Inventory * 365 days) / Cost of Sales

Profitability Metrics

Operating Margin: (Gross Profit Margin * 100) / Net Sales

Sales Margin: (Net Profit * 100) / Sales

Return on Assets (ROA): (Net Profit * 100) / Total Assets

Return on Equity (ROE): (Net...

Comparative Analysis

Comparative analysis is the comparison of financial statements of a company for two or more years to understand performance. It mainly compares the income statement and balance sheet of different years.

Objectives

• Identifying increases or decreases in profits
• Analyzing the growth of assets and liabilities
• Evaluating financial performance

Types

• Comparative income statement
• Comparative balance sheet

Importance

• Helping management in decision-making
• Identifying strengths and weaknesses

Infrastructure Financing

Infrastructure financing means arranging funds for large projects like roads, railways, power plants, airports, ports, and telecom.

Sources Include:

• Government funding
• Bank loans
• Financial institutions
• Public-private partnerships
• Bonds

Market Demand Function and Its Determinants

In economics, a Market Demand Function is the mathematical relationship that shows how the total quantity demanded for a commodity by all consumers in the market is influenced by various factors.

Definition

The market demand function expresses the functional relationship between the total demand for a good and the factors (determinants) affecting it. It is the horizontal summation of individual demand functions of all consumers in the market.

Algebraic Expression

It is typically represented as:

D_x = f(P_x, P_r, Y, T, E, N, D, S)

Where:

• D_x: Quantity demanded for commodity x
• P_x: Price of the commodity
• P_r: Prices of related goods (substitutes and complements)
• Y: Income of the consumers
• T: Tastes and preferences
• E:

The elasticity of demand refers to the degree of responsiveness of quantity demanded of a commodity to a change in its price or any other factor).
The concept of elasticity of demand is of great importance to producers, farmers, workers, and the Government. Lord Keynes considered this concept to be the most important contribution of Alfred Marshall.
The importance of elasticity of demand can be explained with the help of the following points:
1. Importance to a Producer: Every producer has to decide the price of his product at which he has to sell it. The concept of elasticity of demand becomes important for this purpose. If the producer is producing a commodity whose demand is relatively inelastic, then he can set a high price for it. Similarly,...
