Online Shopping: Advantages and Disadvantages

Nowadays, many people prefer shopping online instead of going to physical stores. There are several advantages and disadvantages to this trend.

This document outlines several fundamental business strategy frameworks crucial for analyzing market dynamics, competitive landscapes, and internal capabilities.

PESTEL Analysis: External Environmental Factors

The PESTEL analysis identifies key environmental variables that may influence a business, either positively or negatively. Choosing critical dimensions is essential for effective analysis.

• Political: Government agencies, pressure groups, lobbies, etc.
• Economic: Income, prices, inflation, debt, credit, etc.
• Sociocultural: Population, birth rate, lifestyle, consumption habits, etc.
• Technological: Innovation, technological changes.
• Ecological: Raw materials, sustainability, recycling, etc.
• Legal: Regulations related to competition, consumers, and

Rationale for Regulating Market Failure

Market regulation is essential to address various inefficiencies and failures within the economy.

• Externalities: Examples include pollution, congestion, and education.
• Asymmetric Information:
  • Adverse Selection: Often seen in health insurance markets.
  • Moral Hazard: Common in mortgage origination.
• Market Power (Monopoly/Oligopoly): Generates deadweight losses.
• Policy Responses:
  • Regulation (taxes, price ceilings, and controls).
  • Proactive competition policy (antitrust).
  • Natural monopoly regulation.
• Political Rationale:
  • Rent Seeking: When firms actively lobby for regulation to benefit themselves.
  • Regulatory Capture: When the regulated entity controls the regulatory body.

• Perfect

Determinants of Demand

• Income of the consumer
• Price of the commodity
• Changes in the prices of related goods
• Tastes and preferences of the consumers
• Change in the distribution of income
• Price expectations
• State of economic activity

Production and Cost Analysis

The long-run total cost curve shows the total cost of a firm’s optimal choice combinations for labor and capital as the firm’s total output increases.

In microeconomics, economies of scale are the cost advantages that enterprises obtain due to size, throughput, or scale of operation, with cost per unit of output generally decreasing with increasing scale as fixed costs are spread out over more units of output.

• Monopolistic competition
• Oligopoly
• Monopsony

Chapter 6: Push–Pull

Question 1 — Push-Based vs Pull-Based

When demand uncertainty is low, a push-based supply chain allows the firm to reduce costs by making use of economies of scale in production and distribution without increasing inventory holding costs. A pull-based supply chain reacts to real customer orders rather than to forecasts. Thus, lead times and variability in the system are reduced by matching supply and demand. This leads to improved customer service and decreased inventory holding costs.

Question 2 — Industry Examples

As discussed, the automobile industry has traditionally employed a push-based supply chain strategy by building inventory for the dealer warehouses. On the other hand, in industries in which demand is relatively... Continue reading "Push-Pull Supply Chain Strategies and Examples" »

Absolute Advantage in the Rice Market

Absolute Advantage: Rice is produced in both Vietnam and Japan. Assume demand conditions are exactly the same in both countries. This implies demand curves for rice in the two countries are exactly the same.

Trade often arises due to differences in supply conditions. Assume the supply curve for Vietnam is farther to the right than the supply curve for Japan. At every price, Vietnam supplies more rice than Japan. Perhaps Vietnam uses superior technology or production inputs are lower in Vietnam.

Autarky Rice

• Since no trade is involved between Vietnam and Japan, these two prices are known in international economics as autarky prices.
• Autarky is a situation in which
