Koryos Inevitable Decline essays

Koryo's Inevitable Decline essays Koryo is one of critical kingdoms in Korean history during 10th and 14th century. During Koryo era, cultural aspect of the country flourished in many ways. For example, blue ceramic is a clear demonstration of creativity. Moreover, Koryo made a lot of cultural exchanges with foreign countries, such as contacting with Thailand and Islam cultures. These contacts made the country to experience international differences and contributed to the outgrowth of the country. Unfortunately, Koryo went through extreme chaos at the end of the era. Koryo started to decline because of the invasions of foreign countries, new rules on land policy and the advent of ambitious general, Yi Songgye. Despite of many mutual exchanges with foreign countries, Koryo was attacked and invaded by China and Japan constantly. When a country is attacked by another country numerously, the country loses control on inner affairs and becomes unstable and easier to decline. Geographically, Northern part of Korea is connected to China. Therefore, it was easier for China to invade Korea. At the end of Koryo era, which was 1359, Koryo was attacked by a group called Red Turbans (Han, 178). These aggressive Red Turbans were defeated by the Mongol army (Mongolia was the country right above Northern Korea) and about 40,000 Red Turbans fled to Koryo. They occupied four Northwest towns and took Pyongyang, but they were defeated by Koryo army (Han, 178). However, Red Turbans returned again with 100,000 strong men. All the Northern part of Koryo were destroyed and corrupted. This time, Kaesong (Capital city of Koryo) was in danger. The court had to move down to Andong, which was located in the South. By moving the court, Koryo wasted a lot of capital money. The cost of lives and resources that have been lost from these attacks were the causes of decline. Mongolians have been attacking Koryo on and off for many years before the Red Turbans. For example, in 1231, ...

The Basics Supply and Demand

The Basics Supply and Demand Supply and Demand analysis is relatively straightforward once the terminology is understood. The important terms are as follows: PriceQuantityDemand and Demand CurveQuantity DemandedSupply and Supply CurveQuantity SuppliedEquilibriumSurplusShortage Basic supply and demand analysis is done one of two ways - either graphically or numerically. If done graphically, it is important to set up the graph in the standard form. The Graph Traditionally economists have placed price (P) on the Y-axis and quantity (Q), as in quantity consumed or quantity purchased/sold on the X-axis. An easy way to remember how to label each axis is to remember P then Q, since the price (P) label occurs above and to the left of the quantity (Q) label. Next, there are two curves to understand - the demand curve and the supply curve. The Demand Curve A demand curve is simply a demand function or demand schedule represented graphically. Note that demand is not simply a number - it is a one-to-one relationship between prices and quantities. The following is an example of a demand schedule: Demand Schedule $10 - 200 units$20 - 145 units$30 - 110 units$40 - 100 unitsNote that demand is not simply a number such as 145. The quantity level associated with a particular price (such as 145 units $20) is known as a quantity demanded.A more detailed description of the demand curve can be found at: The Economics of Demand. The Supply Curve Supply curves, supply functions, and supply schedules are not conceptually different than their demand counterparts. Once again, supply is never represented as a number. When considering the problem from the point of view of the seller the quantity level associated with a particular price is known as quantity supplied. A more detailed description of the supply curve can be found at: The Economics of Supply. Equilibrium Equilibrium occurs when at a specific price P, quantity demanded quantity supplied. In other words, if there is some price where the amount buyers wish to buy is the same as the amount sellers wish to sell, then equilibrium occurs. Consider the following demand and supply schedules: Demand Schedule $10 - 200 units$20 - 145 units$30 - 110 units$40 - 100 units Supply Schedule $10 - 100 units$20 - 145 units$30 - 180 units$40 - 200 unitsAt a price of $20, consumers wish to purchase 145 units and sellers which to provide 145 units. Thus quantity supplied quantity demanded and we have an equilibrium of ($20, 145 units) Surplus A surplus, from the supply and demand perspective, is a situation where, at the current price, quantity supplied exceeds quantity demanded. Consider the demand and supply schedules above. At a price of $30, quantity supplied is 180 units and quantity demanded is 110 units, leading to a surplus of 70 units (180-11070). Our market, then, is out of equilibrium. The current price is unsustainable and must be lowered in order for the market to reach equilibrium. Shortage A shortage is simply the flip-side of a surplus. It is a situation where, at the current price, quantity demanded exceeds quantity supplied. At a price of $10, quantity supplied is 100 units and quantity demanded is 200 units, leading to a shortage of 100 units (200-100100). Our market, then, is out of equilibrium. The current price is unsustainable and must be raised in order for the market to reach equilibrium.Now you know the basics of supply and demand. Have additional questions?
