Economies of scale is the increase in efficiency as a company gets bigger. In this case the economy of scale is the creation of larger shipping containers. The great thing about scales of economy is that it has lowered the production cost of products such as the creation of t- shirts for some companies. However as companies have more products to they needed bigger containers to transport their goods. As the supple of t- shirts increases the size of the ship that transports the goods needs to increase in size as well. Maersk lines , the world's biggest shipping container company has decided to increase the size of his ships. The company plans to build 20 ships with a capacity of carrying 18,000 twenty-foot equal units. The company does this out of efficeny in transportation and gas cost. The larger the ship the more it can carry and the less times the ship will have to travel back and forth to transport goods. The increase in ship size than is an example of the economies of scale when bigger = more efficient.

This article discusses how oil is becoming an inelastic good. Although people can arrange their lives to reduce their consumption of oil, quickly there comes a point where it is not possible to purchase a smaller amount of oil. Oil would definitely be considered an essential good.

The article evaluates elasticity in terms of oil supply and demand. it states that there are still untapped oil reserves which are more expensive to obtain and requires more time. As a result, oil is becoming less elastic. it talks of possible ways of reducing oil consumption such as public transport or getting a more fuel efficient vehicle which is unlikely as it is expensive. it also evaluates the the elasticity of supply. it talks off how suppliers need a minimum price/barrel in order to keep a balanced budget so suppliers are reluctant in increasing supply in order to reduced the prices. It provides data over a 10year time period which analyses the oil consumption and supply of oil in terms of different uses and change in costs. It also relates it to the recession stating that job loss has lead to less people commuting decreasing demand and increasing price

The article is talking about the changes in Public goods in different generations.The writer is comparing privatisation and public goods and services.These days, however, the distinction between 'public' and 'private' has become blurred.In Britain, for example, the railways were privatised and an 'internal market' was created within the National Health Service on the grounds that this improved the efficiency of service delivery for 'customers'. There are some circumstances in which it is sensible to privatise, there are many good reasons why wholesale privatisation should be shunned.

This article discusses the new Chevy volt hybrid and debates it's future. it can be said that the company, in regards to this car, is going to start benefiting from economies of scale as in the article it states that the production cost will become cheaper however it is obvious that the company is not producing at the minimum efficient scale as allegedly for each volt it sells, the company loses $49,000

Currently, the Chevy Volt costs $89,000 per car to produce. However, GM is selling the car at about $40,000, offering even more discounts in certain places to reel in customers. GM argues that in the long run, the production cost will decrease and begin to bring in profit.

This article is an excellent example of the concept of long term vs. short term decision making by a company. Right now, GM is losing massive amounts of money whenever they make and sell another Chevy Volt, but they hope the investment will pay off in the long run.

This article talks about an earthquake and the lack of water available.This article essentially talks about how the demand for water was high but the price remained therefore people with more use for the water werent able to get the resource; it; some needed it for baby formula whilst others for cleaning dishes. The writer argues that if the price of the water was raised, as it was scarce, then people with higher priorities wouldn't mind spending the extra money. Economist Eric Cramption then dismisses an argument against price allocating resources; the poor would get poorer. .
