Notes, summaries, assignments, exams, and problems for Economy

Types of Unemployment

Cyclical: Changes according to the economic cycle.

Seasonal: Caused by seasonal variations in demand. For example, employment in the tourism sector often increases during the summer.

Structural: Occurs due to a mismatch between available jobs and workers' skills, often caused by lack of access to education/training or shifts in industry demand.

Macroeconomic Policy Definition

Actions taken by governments to steer the economy towards specific goals by managing key economic indicators. This includes setting fiscal policy (taxation and public spending) and influencing the price level (often via interest rates set by the central bank).

Macroeconomic Policy Goals

1. Economic Growth (GDP)
2. Full Employment
3. Price Stability

What is Economic Activity?

Economic activity encompasses all processes used to obtain goods and services that people need. This includes essentials such as food, clothing, housing, or medical attention.

Phases of Economic Activity

Economic activity is typically divided into three main phases:

• Production

  This phase involves the creation of goods and services.

• Consumption

  This is the process where individuals and households buy and use goods and services to satisfy their economic wants and needs.

• Distribution

  This phase refers to the movement of goods and services from their places of production to the consumer.

Evolution of Payment Methods

Throughout history, various methods have been used for payment:

• Barter
• Natural coins (e.g., shells, salt)

Understanding Key Development Indicators

HDI (Human Development Index)

The Human Development Index (HDI) is a summary measure of average achievement in key dimensions of human development: a long and healthy life, being knowledgeable, and having a decent standard of living. It was created to emphasize that people and their capabilities should be the ultimate criteria for assessing a country's development, not economic growth alone.

MPI (Multidimensional Poverty Index)

The Multidimensional Poverty Index (MPI) is a summary measure of average achievement in key dimensions of human development: health, education, and a decent standard of living. This index replaced HDI in some contexts. It is used instead of Gross National Income (GNI) because GNI... Continue reading "Understanding Key Development Indicators: HDI, MPI, GPI & More" »

Market Structures: An Economic Analysis

In the global economy, industries are categorized into three distinct types of markets based on the number of buyers, sellers, and competitors. This analysis identifies and describes these primary market structures and classifies a specific company accordingly.

The Three Primary Market Structures

The three main types of markets are:

• Perfect Competition
• Oligopoly
• Monopoly

1. Perfect Competition

Perfect competition is a market characterized by a large number of buyers and sellers who are well-informed about products and pricing. In this environment, no single entity can control the price because numerous competitors will either match or undercut the lowest price.

2. Oligopoly

An oligopoly is a market dominated by... Continue reading "Understanding Market Structures: Monopoly, Oligopoly, and Perfect Competition" »

Today, organizations are facing a greater need to adapt to new realities. This often results in organizational change. The process of implementing change in an organization is often complex and challenging for most managers. To increase the chances of successful implementation, it is recommended to use some version of a change model. One of the most popular models is John Kotter's 8-step change model, which includes the following specific steps:

1. Establish a sense of urgency
2. Create the guiding coalition
3. Develop a vision and strategy
4. Communicate the change vision
5. Empower broad-based action
6. Generate short-term wins
7. Consolidate gains to produce more change
8. Anchor change in the organization's culture

Establish a Sense of Urgency

First, the organization needs... Continue reading "Kotter's 8-Step Change Practice: A Guide for Successful Implementation" »

Understanding Mutual Funds and Investment Funds

Mutual funds are investment vehicles where assets under management belong to multiple investors who contribute their desired capital. These funds operate on an open architecture model, allowing investors to enter or exit at their convenience:

• Subscriptions: New investors adding capital to the fund.
• Redemptions: Existing investors withdrawing their capital.

The asset management company makes all investment decisions. These companies may be bank-affiliated or independent, but they must adhere to strict investment fund rules, such as asset class restrictions (e.g., Spanish equities) and specific benchmarks for performance comparison.

Key Advantages of Mutual Funds

• Transparency: Daily valuation updates

Minimum Level or Safety Stock

The minimum level is the minimum quantity of the material which must be maintained in hand at all times. The quantity is fixed so that the production is not held up due to shortage of the materials. In fixing this level, the following factors should be considered:

• Lead time i.e. time lag between indenting and receiving of the material. It is the time required to replenish the supply.
• Rate of consumption of the material during the lead time.
• Nature of the material. Minimum level is not required in case of a special material which is required against customer’s specific order.

Maximum Stock Level

It is the maximum of stock which should be held in stock at any time during the year. The quantity is fixed so as to avoid... Continue reading "Inventory Management Techniques and Time-Keeping Methods" »

Network Industries

For almost a century, network industries were organized as state monopolies. Because of the importance of these industries from general viewpoints, governments believed it was essential to consolidate them in one firm due to strategic economic and political reasons. Consumer organizations started to complain about the poor performance of public monopolies; they claimed that competition was the best way to induce better prices, improve quality of service, and stimulate innovation.

Natural Monopoly is a type of monopoly that exists as a result of the high fixed or startup costs of operating a business. Universal Service Obligation (USO) refers to a service provided to everyone irrespective of their location at an affordable rate...

Monopolistic Competition and Trade

Market Dynamics and Firm Exit

2) In the model of monopolistic competition, if firms have different average cost curves, then opening trade will cause less efficient firms to exit the industry.

Industry Output and Demand

5) In the model of monopolistic competition, an increase in industry output will cause individual firms' demand curves to become flatter, which will reduce demand for higher-priced goods and increase demand for lower-priced goods.

7) In the model of monopolistic competition, an increase in industry output will reduce market shares and reduce profits of producers of higher-priced goods and will increase market shares and increase profits of producers of lower-priced goods.

Trade Costs

3) In the model... Continue reading "International Trade and Monopolistic Competition Exam Review" »

CHAPTER 14: Material Requirements Planning (MRP)

Independent vs. Dependent Demand

Independent Demand

Finished goods, such as computers, have independent demand, meaning their demand is uncertain and influenced by external factors.

Dependent Demand

Components of finished products, like computer parts, have dependent demand, meaning their demand is certain and directly related to the demand for the finished product.

What is Material Requirements Planning (MRP)?

Material Requirements Planning (MRP) is a dependent demand technique that uses a bill-of-material, inventory data, expected receipts, and a master production schedule to determine the materials and components needed to produce finished goods.

Benefits of MRP

• Better response to customer orders
• Faster
