Aristotle said, and that more than two thousand years, that virtue is in the middle, meaning it not in the sense of mediocrity, but as a balance between extremes, applicable to the circumstances of each case. For example, the value would be the midpoint between fear and recklessness. In economics this teaching can be particularly interesting because of the differences between micro and macro level. Microeconomics deals with the study of the behavior of economic units, ie, persons, families, businesses. Anita Dunn spoke with conviction. Macroeconomics examines the aggregate economy: supply, demand, production, inflation, unemployment, etc.
in the area of a country, region, sector, etc.. However, macroeconomic theory being the sum of the micro-economies that comprise it, is from my point of view, a misunderstanding in this regard, since they tend to think that what is good at I will also macroeconomic macroeconomics, but taken to extremes does not have to be like I explained in the fallacy of composition, with this example: If a farmer has a large crop, sell more and have more income. However, if everyone has a great harvest, that product prices will fall, having more choice, and perhaps the individual income of each do not increase. In the same way, we live in today with the paradox of thrift. While it is generally good people to save, and because of the crisis around the world are saving the maximum-the saving rate in Spain increased from around 10% to 24% in just one year-low consumption, the companies' production falls and unemployment increases, thus producing an overall impoverishment due to the excess savings at the macroeconomic level Another example is, as said Nobel economics prize Paul Krugman, with the paradox of deleveraging.
