This is a very interesting article that really helps understand this topic in depth and with real examples. Oil market is one of the largest in the world, this article talks about elasticity of demand and supply in this market. There is an explanation on the effects of different factors that determine the elasticity and what they do for this market. 

Although there are discovered new sources of oil (e.g. in Saudi Arabia), the suppliers have to drill deeper which is time-consuming and therefore the costs of production rise. 'In economic terms, the oil supply is becoming less elastic as new oil supplies come increasingly from unconventional oil.'

This article talks about the economic implications of imposing a tax on carbon emissions and how this would affect the different social classes of society in different ways. The article makes specific reference to economic theory and the elements on elasticity.

Taxation almost always decrease the economic surplus and therefore it makes a decline in effectiveness. In this case, the energy companies will be the most affected group.

The article talks about the fact of how cigarette taxes are increasing due to the elasticity of demand

Very interesting article Aleksi however I believe the taxes on cigarettes are so high also because it is a product which affects the consumer's health negatively

This article talks about price discrimination. In Australia, the government things that the prices are higher than anywhere else in the world ( prices charged by foreign companies). In my opinion, this is because these major companies had the ability to discriminate, due to income, which is found to be higher and the geographical destination. It is a third degree discrimination. All the required conditions for discrimination were available. The companies have ability to set prices, as they are in an oligopoly competition. The consumers in other parts in the world are not likely to by the product and sell it to Australians. And price elasticity in Australis is found to be higher due to the higher income they have, 

The author describes inelastic demand taking the Super Bowl as an example of pricing in many other sports.

This article describes how many sports events try to keep their prices low, in order to maximize attendance and thereby complementary costs such as food and parking. However, the Superbowl tickets are very expensive, and increasing in price. This is because they want to earn more money purely on ticket sales, and they believe they can make more revenue because the high prices only show how special this event is, which means there is a high demand to meet the high prices.

This article shows how when the prices of luxury goods decrease, the demand increases. Usually, Apple's products are quite expensive, but by decreasing the price, it attracts more consumers which shows that their product is price elastic.

Gasoline has a very inelastic demand. It became an essential product because it is used to produce energy, to use cars and for so many other functions. This article discusses if the elasticity of gasoline may is zero or not. Even the fact they are discussing it means that gasoline is essential because if its elasticity is considered to be zero or a little more it shows how important the product is and how muche the price of the product doesn't affect significantly the demand for it.

This article smoothly discusses the PED of gasoline. It's worth reading because it examines it clearly and quite precisely - e.g. taking into consideration time. It shows that gas is an inelastic good, due to the fact that it's really necessary and commonly used. This text ends with a nice conclusion stating that one's never fully sure about the changes in economy.

This article is about how the rising oil prices affect the companies that produce sugar. The article tells us that sugar is inelastic because of many factors, for example very few substitutes so by rising the prices of sugar in the market, it does not really affect the demand for it.

This is a question about price elasticity, since something needs to be improved in the quality of the website so there will not be problems anymore, often resulting in a necessary price change. Since health insurance is seemed as necessary for many and hence the responsiveness is big, the demand might not change as much in a change in price of the website even tough there are problems at the website. If there will not be an improvement of the website and the price will increase, there might be a smaller change in the quantity demanded.

This article shows the best possible market where inelastic demand is common. The oil and gas are the products that have the price elasticity of demand below the one. It is caused by the cooperation of the industries and miners as well as it is really hard to find such a good substitutes for it.

This is an interesting artice that shows how solar phtovoltaic is taking over, reducing the demand of substitute sources of energy but mostly, increasing their elasticity. With PV on the market, more people will be ready to abandon coal or oil for this clean and durable energy source.

I choose this article because it tells about what external impacts (nature) can have on a budget. It's not directly talking about price elasticity, but more about how another "product" (the wildfire) can steel the revenue (money spend) from the other "product" (keeping the nature heathy). I think that this dilemma can apply to other thing like normal products.

This article shows how a small change in demand, effect the sales and the profit of a buisness due to lower chicken prices.

this article shows use of instruments that are in the hands of government. government in Indonesia imposed excise on petrol which is very common example of good with inelastic price elasticity of demand. The possible reason is that petrol is essential good. moreover, they want to use money gained from higher excise to give subsidies for the poorer households.
