Please excuse if I am wrong because I am admittedly not completely sure if I am interpreting this right. I believe that this article tells us that Ireland's banks up to now were in no state of allocated efficiency because the equilibrium had to be manually shifted by the EU paying money to the irish banks. This however has changed now because they are leaving the bailout program which shows that they are trying to get onto their own feet again, and no longer need help from the EU. From this I can conclude that the Irish banks are at least moving towards a state of allocated efficiency again.
This article shows that there clearly is a demand for a phone which will not be dated after only about one or two years. If this project will be realized and the phone goes into series then it will be a serious competitor to the iphone, and the demand curve for iphones will move to the left because now there is an alternative product which is cheaper.
This article is a good example of scarcity I believe because, it shows that there is a huge demand for robotic self-driving cars or in other words, they are scarce. This leads to many companies like google or Tesla starting to develope self-driving cars because they know that due to the scarcity of the product, they can charge big amounts of money and make a huge profit.
