This article describes the effect of price ceilings on goods in Asia. Most countries in Asia have set caps to petrol prices and only seldom raised these. Commentators argue that if price of petrol does not rise with the price of the crude oil in the world, consumers in Asia (where the price for petrol is low) will use up so much that the price of petrol will increase too much and harm the economy rather than help it. In China foods have been monitored as well. Price have a ceiling and if this is to be raise the company must seek approval of the government. This is only a temporary answer to the problem of keeping prices low.

The Australian government needed, as many other governments do, more revenue. They decide to implement a carbon and mining levy tax. The carbon tax forces firms to pay 23 australian dollars per tonne of carbon dioxide, shifting supply to the left, as carbon dioxide produced forces tax on the firms as well as encouraging them to leave less of a carbon footprint.The mining levy tax, puts a direct ad valorem tax on firms who gathering iron and coal. These taxes have allowed for worker's taxes to be decreased, therefore shifting the tax burden from workers to firms that are enviromentally harming.

In this article the company Norsk Hydro decided to change the raw material they produce for German rolling mills to 'increase in-house primary metal sourcing, replacing less cost-efficient remelting of cold metal as a source for its Neuss-Grevenbroich rolling mills.' This is supposed to optimize to the current issue in the market. The Neuss mill will increase production of aluminium to 150,000 tonnes per year unlike the last few year in which it only produced 50,000 tonnes. The factories have a maximum production limit of 230,000 tonnes. Although the tonnes created per year are now increased, it is still not exploiting the maximum point. This point may not be profitable due to limited demand in the market. Maybe the supply and new improvements including framework, CO2 compensation and more efficient smelters will increase the demand.

Although this article shifts supply to the right as there are technological advancements such as better smelters, there is also a movement along the supply curve as the company is getting closer to exploiting their maximum production point. In this case they state that supply is higher than demand. At the moment they have a surplus so the producer must decrease the price so that the quantity demanded will increase. The product, because of the surplus, is less valuable and as there is more quantity it is not as scarce as before. Related markets can buy the aluminum at lower price, increasing their benefit. The producer of aluminum must reduce resources allocated into production to return to the equilibrium point.

Gold Demand falls (16. Aug 2012)

This article shows the fact that the demand for gold dropped. The global demand fell by 7 pc within three months up until the end of June. The World Gold Council stated that this is due to economies facing challenges as well as extremely high sales last year. The analysis also says that this is due to taxation on gold (mainly jewelry) in India. Luckily India is only one of many in the gold market, therefore It did not affect the demand too much. This relates to our discussion in class by addressing the fact of the demand curve moving to the left (the demand is decreasing). India's demand of gold may have dropped due to the new taxation has supply is limited.
