1. Sunk Costs

Costs that do not vary according to different decisions

• Eg. A student buys a book for $50 and can sell it for $20. Sunk costs amount for $30
• Eg. Market research, R&D (frequent in IT sector)

Managerial decision-making:

1. Ignore sunk costs and consider only avoidable costs to be very careful before committing to costs that will become sunk, since such commitments cannot be reversed
2. Exploit investments in sunk costs as a way to strategically influence the behavior of competitors

- Major entry barrier because they increase the cost of exit

Relationship between fixed and sunk costs: - sunk costs are the amount of fixed costs that cannot be recouped

2. Incremental Costs

Change in costs between undertaking a course of action and not undertaking... Continue reading "Cost Concepts and Pricing Behavior" »

Individual vs. Team Sports: Which is Better for Child Development?

The Benefits of Individual Sports

With the evolution of modern society, new activities have emerged for children, such as learning languages or playing musical instruments. However, one of the most popular activities is participating in sports. Parents often encourage their children to engage in sports to develop essential life skills. While both individual and team sports offer benefits, individual sports can be particularly advantageous for skill development in children.

In team sports like basketball or soccer, the outcome depends on the collective effort. A child on a struggling team, or one who lacks certain skills, may experience frustration, stress, and even bullying.... Continue reading "Individual vs. Team Sports: Skill Development in Children" »

Why is the Purchasing Activity Becoming More Important to Global Firms?

Over the past three decades, increasing global competition has caused a dramatic increase in the outsourcing of materials. Firms are demanding the best value for all components used in finished products. Parts that were produced in-house as a matter of corporate policy are now being purchased from suppliers around the world. For a typical manufacturing firm, the share of finished product cost that is represented by purchased parts (as opposed to in-house) can range from 40-60%. As a result, purchasing is becoming a key success factor, and the current movement towards even greater international trade will only increase its importance.

What are the Tasks and Goals of Purchasing?

Does the Purchase of Government Debt by Monetary Authorities Enhance Macroeconomic Policy?

Yes, this is actually what happened in the aftermath of the financial crisis that led central banks (CBs) to buy large amounts of public debt. The explanation is as follows:

Impact of Central Bank Debt Purchases on Liquidity

When the CB buys a large amount of government debt, it implies a higher volume of liquidity injected into the economy. Once the volume of liquidity is such that the interest rate market hits the lower bound of the corridor (deposit rate), further injection of liquidity (quantity) allows them to also control the interest rate (price). The internal market will not fall further as the CB dominates all other aspects of the economy, and the... Continue reading "Central Bank Debt Purchases: Impact on Monetary Policy" »

The Role of Institutions in Economic Growth

Conditions for Beneficial Institutions

Several conditions contribute to the emergence of institutions that foster economic growth:

• Political Checks and Balances: Institutions that limit the power of political actors, such as through a balance of power, encourage the development of sound economic institutions.
• Broad Distribution of Power: When political power is dispersed among a wider group with substantial investment opportunities, the likelihood of favorable economic institutions increases.
• Limited Rent Extraction: Restricting the ability of those in power to extract excessive rents from society discourages the establishment of institutions that facilitate exploitation.

North and Thomas's Perspective

According... Continue reading "Economic Growth and Institutions: A Comprehensive Analysis" »

Impact of Pressure Groups on Economic Growth

Pressure groups interfere with the economy's capacity to embrace innovation and thus reduce the rate of growth. For example:

• A labour union may repress labor-saving innovation
• Slow decision-making may cause delays in adapting to new technologies
• Pressure groups may slow growth by reducing the pace of resource reallocation

Olson’s theory of collective action suggests that the structure of pressure groups affects the distribution of income and individuals' incentives, impacting long-run economic performance.

Significance of Economic Institutions in Long-Run Economic Growth

The prosperity of a society depends on its economic institutions. Market failures provide a rationale for government intervention, and... Continue reading "Impact of Pressure Groups on Economic Growth and Institutions" »
