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

Loan Amortization Methods

Bullet Method

• OLEY₀ = P
• OLBYt = OLTYt−1 (Same until last year)
• It = EAR · OLBYt (Constant until last year)
• PBt = 0 (Except last year, where PBt = P)
• At = It + PBt (Constant until last year)
• OLEYt = OLBYt − PBt (Must be 0 in the last year)

Straight Line Method

• OLEY₀ = P
• PBt = P/n (Constant every year)
• OLBYt = OLEYt−1 (Decreases every year)
• It = EAR · OLBYt (Decreases every year)
• At = It + PBt (Decreases every year)
• OLEYt = OLBYt − PBt (0 in the last year)

Annuity Method

• OLEY₀ = P
• A = P · EAR · (1 + EAR)ⁿ / ((1 + EAR)ⁿ − 1) (Constant every year)
• OLBYt = OLEYt−1 (Decreases every year)
• It = EAR · OLBYt (Decreases every year)
• PBt = A − It (Increases every year)
• At = It + PBt = A (Constant)
• OLEYt = OLBYt − PBt (

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,

Monopoly vs. Perfect Competition

The main differences between a monopolist and a competitive firm are that in the case of a monopoly, there is greater scope for establishing the price, although this control is not absolute. The monopoly firm has more freedom to adjust both the price and the quantity produced in their attempt to maximize profits.

Social Impact and Price Discrimination

From society's point of view, a monopoly involves less desirable effects than those derived from economic competition. In general, a monopoly results in lower production of goods and services than would result under competitive conditions, often with higher prices. Another common practice of a monopoly is price discrimination, which involves charging different prices... Continue reading "Monopoly vs. Perfect Competition: Key Market Differences" »
