Unit III: Cost of Capital and Capital Structure

6. Explain the Concept of WACC with Examples

Meaning

Weighted Average Cost of Capital (WACC) is the average cost of all sources of finance weighted according to their proportion in the capital structure.

Importance

• Used as a discount rate in capital budgeting
• Measures the overall cost of finance
• Helps in capital structure decisions

WACC represents the minimum required return expected by investors and creditors.

7. Describe the Modigliani–Miller (MM) Approach

Meaning

The MM approach states that under perfect market conditions, capital structure does not affect the value of the firm.

Assumptions

• Perfect capital market
• No taxes
• No transaction costs
• Investors behave rationally
• Equal borrowing rates for firms and

What Is a Financial Market?

A financial market is a broad term describing any marketplace where buyers and sellers participate in the trade of assets such as equities, bonds, currencies, and derivatives.

The Three Types of Financial Markets

1. Money Market

A market where financial securities mature in less than one year.

Purpose: Its primary objective is the lending and borrowing of money.

Key Concepts:

• Short-term: Refers to the duration of securities traded in this market (less than one year).
• Central Banks: Institutions that lend money to commercial banks, which then use those funds to lend to others.
• Commercial Banks: Financial institutions that provide various financial services and handle loans.

2. Credit Market

Definition: A market involved in the...

What is Working Capital?

Working capital is the capital required for the day-to-day working of an enterprise. It is required for the purchase of raw materials and for meeting the day-to-day expenditure on salaries, wages, rents, advertising, etc. Working capital is also called circulating capital, revolving capital, floating capital, or liquid capital. It is also known as operating capital.

Components of Working Capital

A. Current Assets

Current assets are those assets which can be converted into cash in the normal course of activity of a firm, usually within one year. Examples of current assets include:

• Cash and short-term investments
• Bank balance
• Bills Receivable (B/R)
• Stock of raw material
• Stock of finished goods
• Sundry debtors
• Prepaid expenses
• Advance

Understanding International Development

International development refers to the effort to improve the economic, social, and political conditions of lower-income countries. It recognizes that countries differ not only in income levels but also in health, education, and institutional strength. Development therefore goes beyond economic growth and includes poverty reduction and human well-being, as reflected in global frameworks such as the UN Sustainable Development Goals.

International Political Economy (IPE) Perspectives

Different IPE approaches define the development challenge in distinct ways:

• Economic Liberalism: Argues that underdevelopment results mainly from poor domestic policies and weak institutions, promoting free trade, open markets,

1. Corporate Internationalization: Forms and Strategies

Corporate internationalization occurs when a company expands its business beyond its home country.

Main Forms of Internationalization

• Exports: The company produces in its home country and sells products abroad.
  • Example: A Spanish winery selling wine to Japan.
• Commercial Delegation: Production stays at home, but the company establishes a sales office or employs salespeople abroad.
  • Example: A French company with a sales office in Brazil.
• Production Plant Abroad: The company builds factories in the foreign country to produce and sell locally.

  This strategy helps reduce transport costs and avoid tariffs.

• Internationalization of Purchases: When a company buys materials or products from abroad.
• Imports:

1. Shifters of Supply and Demand

• Supply Shifters: Price of related goods, input prices, technology, expectations, and number of producers.
• Demand Shifters: Price of related goods, income (normal vs. inferior), tastes/preferences, expectations, and number of customers.
• Distinction: Change in quantity supplied/demanded (movement along the curve, caused by the price of the good) vs. Change in supply/demand (shift of the curve, caused by external factors).

2. Comparative vs. Absolute Advantage

• Absolute advantage: Producing more output with the same resources.
• Comparative advantage: Lower opportunity cost per unit produced.
• Formula for opportunity cost: "Other thing / something".

3. Production Possibility Frontier (PPF)

• Shifters:
  • Factors of production (land,

The Prisoner's Dilemma

The Prisoner's Dilemma is a fundamental concept in economics and game theory. At its simplest, it illustrates why cooperation can be challenging, even when mutually beneficial. This difficulty arises because one party cannot reliably predict the other's actions. For example, consider two farms alongside a river. The river will flood unless $1,000 is spent on flood control. Both farmers will suffer significant losses if it floods. The optimal solution is for both farmers to pay $500 each. However, each farmer knows that if the other farmer paid the full $1,000, they would receive the benefit of flood control for free. Consequently, each waits for the other to pay the entire $1,000. In the meantime, the river floods. This...

Sustainable Development Goals (SDGs)

Purpose of Sustainable Development

1. Reduce inequalities.
2. Caring for the environment.
3. Promote collaboration between social agents (productive agents).

Five Dimensions of the SDGs

The SDGs are "unique and special" in at least five dimensions:

1. All countries participate.
2. Target three dimensions: environmental, economic, and social.
3. All kinds of partners are involved.
4. Institutionally integrated.
5. More visible in public discourse.

Key Sustainability Metrics for Profitability

• Energy Efficiency and Cost Reduction
• Waste Reduction
• Water Efficiency
• Supply Chain Sustainability
• Brand Reputation
• Regulatory Compliance
• Productivity and Employee Engagement
• Innovation and New Product Development
• Carbon Footprint Reduction
• Return on Investment (ROI)

Functions of the Financial System

• Facilitating Savings and Investments: The financial system connects savers and investors by providing platforms like banks and stock markets.
• Efficient Resource Allocation: It directs funds toward productive projects, fostering economic growth.

Understanding Time Deposits

• A time deposit is a bank account where money is deposited for a fixed period. In return, the depositor earns higher interest than a regular savings account. Withdrawals before maturity may incur penalties, ensuring the bank can use the funds for longer-term loans.

Demand for Money: Transaction Motive

• The transaction motive refers to holding money for everyday purchases and payments. It depends on income levels and the frequency of transactions.

Introduction

Hello, my name is Tomas Mastronardi. Today I'm going to discuss international trade and two important ideologies: free trade and protectionism. We'll also explore trade wars, global trade tensions, and conclude with a summary of the key arguments.

Free Trade

Free trade promotes the unrestricted flow of goods and services across borders. Proponents argue that removing barriers to trade leads to economic growth, efficiency, and consumer benefits. Free trade agreements, such as the North American Free Trade Agreement (NAFTA) and the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP), aim to reduce trade barriers and promote market access.

Protectionism

Protectionism, conversely, seeks to shield domestic industries...
