I would consider the flow of people as one of the most important types of flows in our times today. Here in Austria, and all over Europe, we face a huge amount of immigrants coming to our borders with the hope of a better life. This type of flow immediately influences the stocks that are available in countries like Austria, Germany or other affected countries in Europe. The type of stock i am referring to is food. You could say once the flow of immigrations increases, the stock of supplies, like food and/or medicine, declines. Just take a look on the news here in Austria, even if it is not that big of a issue anymore in 2017, but think of 2015. Thousands of people from Vienna helped immigrants arriving at the central station with supplies and food, representing the stock. So stock and flow was totally emerged in that situation. Another type of stock influenced by the flow of people is land and linked to it the cost of land. We talk of 4000 - 5000 euro per squaremeter here in Austria when buying a house or appartement. A situation totally caused by the lack of land, in this case the type of stock, and the continuing growth of the flow of people. Costs for living will explode and the available land decreases and gets more expensive every day. You could use these informations, based on stock and flows, for simply making better and smarter politics in Europe and especially the EU. We could use the difference between flow of people and stock of land to form and build new housing areas for an affordable price by analyzing the specific needs of people and the availabe money. A good example would be the Aspern Seestadt in Vienna. A huge housing, even a city, project emerged from an old airport, where now thousands of people, from immmigrants to bankers, live together. Another example would be the first types of projects like these, the impressive garden cities by Ebenezer Howard in England. I would totally say these projects could have been build today on the principles of stocks and flows. The picture is from Google. I do not own it. Just to make my statement clear.
