Elasticity

Arguably the leading company in technology right now is Apple. Everything they sell is extremely popular. There are lineups outside shop doors whenever there is a new product of theirs that hits stores. It is rumored that Apple will launch their newest product on October 17^th; the iPad mini.

The new iPad is highly anticipated with orders reportedly at 10 million units. Experts say that the major factor that determines the success of the new iPad is the price. If the price is below $300, then great success is anticipated.

Price elasticity of demand is the responsiveness of quantity demanded to a change in price. If demand for the new iPad is as high as predicted, then the demand will be inelastic, meaning that the quantity demanded is not very responsive to a change in price. The maximum price in this case is very important because if the price exceeds $300 then the demand will be elastic or is quite responsive to a change in price and demand will be at its lowest point. It is also worth noting that unitary elasticity is the point the percentage change in quantity is exactly equal to percentage change in price, so then, total revenue does not change.

Here is a graphed example of elastic and inelastic demand of the new iPad:

To calculate elasticity we simply take the percentage change in quantity and divide it by the percentage change in price. If the elasticity is over 1, then we have elastic demand. Elasticity demand of 1 is unitary and elasticity below 1 is inelastic.

The bottom graph shows how elasticity effects total revenue. At the midpoint, revenue is at a maximum while demand is unitary.  When price elasticity of demand is greater than 1, the total revenue rises. Also when price elasticity of demand is less than 1, the total revenue falls.

Determinants of Demand

Determinants of demand are normal products, inferior products, substitute products and complementary products. The demand of normal products increase as income increases and demand decreases when income decreases. An example would be the latest video games. As our income increases, so does demand for video games. The demand decreases while our income does.

Inferior products on the other hand are products that experience an increase in demand as our income decreases and a decrease in demand as our income increases. No name brand products would be an example of inferior products. As income decreases, the demand for no name products rises.  As income increases, the demand for no name products decreases and there is an increase in demand for brand name products.

Switching from brand name products to no name products is an example of substitute products. If the price of a product increases, then there will be more of a demand for a similar product.

The demand for complementary products is related because they are purchased together. If you recall the video game example, let’s say that there is a new games console released and there is a high demand for it. Then there would also be an increased demand for accessories such as games, cables, extra controllers, etc.  

 Another example of substitute products effecting demand would be in the case of the Chicago Tylenol scare in the 80s.

There were a number of bottles of Tylenol that had been tampered with. Seven people died as a result of taking extra strength Tylenol with traces of cyanide in the capsules. Johnson & Johnson recalled all their bottles of Tylenol. Demand for Tylenol dropped significantly until the late 80s when Tylenol was re-launched.  While the demand fell for Tylenol, demand increased for substitute products.

Diner City

I recently played the game Diner City. The game allows you to run a restaurant and compete with another one. You start with one employee and $50. From there you can decide what improvements you can make to the restaurant by making certain purchases. Most purchases increase revenue per customer while others add seats to the restaurant. You also get to see what your opponent is doing. The object of the game is to beat your competitor in revenue and sales.

When the game begins there is a scarcity of resources. Here the scarce resources would be money and employees. The game is also showing an example of working in a competition economy. As you accumulate more money, you can accumulate more employees and resources; increasing the speed of service and revenue per customer.

Production Possibilities

The production possibilities curve graph shows a combination of outcomes when two items are produced. It shows how the production of one product effects the production of another when production is increased or decreased.  The PPC curve shifts to the dotted position due to improvements in technology which increases productivity.

The graph demonstrates scarcity, opportunity cost and choice by showing that in order to produce one product; we have to produce less of the other. We must make a choice by deciding which product we need more of.

One opportunity cost I have experienced by returning to school is that I work less and therefore make less money. More school, less work. A choice I have made based on scarcity would be choosing returning to school over guitar lessons. Deciding to complete my post secondary education in hope of a better career over continuing my hobby will hopefully pay off in the future. In this case time and money are limited.
