Figure 1: Movement along the demand curve of Samsung smart phones
Figure 1 shows the movement along the demand curve for the Samsung smart phones. As the price of the smart phones falls from P to P1 due to the release of new smart phone models, the quantity demanded for that the older smart phone will increase from Q to Q1. There is a downward movement from point A to point B as demand increases for older smart phones.
Figure 2: Shift of demand curve of Samsung smart phones
Based on Figure 2, the demand curve shift to the right from D1 to D2 while the price remain constant. The quantity demanded increases from Q1 to Q2. The shift happens due to changes in determinants. In reality, the determinants of demand such as income, prices of related goods, tastes, expectations and so on do not remain constant and keep on affecting demand. As a result, when one of the factors affecting demand changes, the demand curve will shift either to the left or right.
In Figure 2 it shows the increase in demand for Samsung smart phones as the demand curve shifts to right due to a few determinants. In income factor is where the income of a person affects his or her expenditure. For example, a person who obtains a higher income would want to buy the latest Samsung smart phone rather than buying other simple and cheaper smart phone. Thus, the Samsung smart phone is considered as a normal good whereby it is a good for which other things is kept constant, increase in consumer income leads to an increase in demand (Mankiw, et al., 2011). Another factor affecting demand is the price of related goods. For example, Samsung and Apple are both in the competitive smart phone market. The new S4 and the iPhone5 are two smart phones that can satisfy similar desires of every consumer. When the price of one of the two goods falls, the demand for the other good is reduced hence, the two goods are substitutes. So, when the price of the Apple iPhone5 increases, the demand for the Samsung S4 will increase too as more people will now buy the Samsung S4. The image below shows the battle between Apple and Samsung in the US in sales (Arthur, 2013). From this image, we can tell that Samsung smart phones have inelastic demand since people will still buy it at any given price because smart phones has become a necessity in today’s world.

Consequently, the supply of Samsung smart phones is increasing to cope with its increasing demand especially during the release of new smart phones models. The law of supply states that the quantity supplied of a good rises when the price of the good rises while other things remain constant (Mankiw, 2009). So, as the price of the Samsung smart phones increases, the quantity supplied also increases. For example, the supply of Samsung S4 shipped worldwide is about 60 million units (Lilly, 2013).
Figure 3: Movement along supply curve of Samsung smart phone
Based on Figure 3, the price of the smart phones is increasing from P to P1 thus the quantity supplied increases to from Q to Q1 and there is an upward movement from point A to point B indicating the increase in supply.
Figure 4: Shift of supply curve
Figure 4 shows the shift of the supply curve to the right of the Samsung smart phones from S1 to S2 while the price remain constant. The supply curve shifts due to the changes in determinants of supply. The main factor that is related to the shift of the supply curve of the Samsung is technology. Samsung was named the best supply chain in Asia in 2013 due to the usage of advance technology and segmentation, Samsung was able to improve the supply of its smart phones and reduced cost (Donati, 2013).
Upon releasing its new smart phone models, Samsung has encountered shortage of supplies in the US. This happens recently to the S4 (Anon., 2013) and also to its predecessor the S3 in 2012 (Sadewo, 2012). A shortage occurs when there are too many buyers in the market pursuing goods that has low supplies.
Figure 5: Market not in equilibrium
As illustrated in Figure 5, there is a shortage of Samsung smart phones because P is below the equilibrium price, Pe. At P, shortage occurs because the quantity supplied is lower than the quantity demanded. This may happen upon the release of a new model whereby the price of the smart phone has not been announced yet so there will be many speculations (Johnson, 2013). As the price of the smart phones rises, the quantity demanded falls, and the quantity supplied increases, the market will once again move towards equilibrium.
Recently, the US government has made the decision to ban some of Samsung mobile technology due to the company’s violation of patents owned by Apple (Anon., 2013). The US International Trade Commission has rejected Samsung’s effort to overturn its ban on some older model of Samsung smart phones and tablets for patent infringement (Anon., 2013). The result of the government intervention is a $1billion loss for Samsung shares on the stock market and Apple gets the opportunity to capitalize in their settlement talks with Samsung about its pending patent disputes (Kale, 2013).
In conclusion, as the No.1 company in smart phones manufacturing Samsung is definitely in its own elite league as the company is able to produce a line of smart phones that is one of a kind and also serve the needs of the consumers. In no doubt, Samsung will continue to strive to make more advanced and high tech smart phones that can make people’s lives easier, simpler and more interactive.
