Economics Commentary 1

In this assignment I will investigate an article from the point of view of an economist. Furthermore I will explain the linkages between concepts and theories of microeconomics and the article.

People have more gas than they need, which means that the value of gas drops. But traders still need to sell their gas because it would be inefficient. The solution is to make more people buy gas, which means an increase in demand. You can increase demand by lowering the price. To bring the market to balance again operators are pumping surplus gas into storages to prevent further decrease in price. By injecting gas into

storages you decrease the quantity of gas...
