The Chimera of Macroeconomics

  What is mathematically true can be false in economics. 3)                  Nonentity vs Entity vs Infinity             We can and often do classify all matters in two greatest categories, that is, entity (1) and nonentity (0). We call it a “ binary system ,” which happens to be the computer language . Then on, we can divide the entity into as many sub-entities as we wish with each still existent. On the flipside, we can never create an entity however many nonentities we may amass.              Particularly in mathematics, we sometimes refer to “ infinity .” Come to think of it, as for the entity, infinity is on the other side of nonentity: we can never build up infinity with however many entities, large or small. Right, nonentity is also called “ infinitesimal ” in mathematics; we w...

  If any of us gives us any number, we can prove that the number might represent the US GDP of a certain year in an imaginary currency unit, say, bancor .            Suppose that the number given happen to be 123,456,789,000 and the US GDP of 2023 be 27.4 trillion dollars . First, we revise the given number to 123 billion bancors because the digits smaller than the “margin of error,” which is innate to the nation-wide survey for an estimation of GDP, have no merit at all to quote. Further suppose that the exchange rate be 223 dollars per bancor . Then, the GDP 123 billion bancors equals to 27.4 trillion dollars . Q.E.D. The Point . The dollar is no less arbitrary than the bancor is imaginary. Therefore, the true meaning to our life comes from relativity either in the dollar or in the bancor ; that is, either interspatial or intertemporal comparison , which in turn is for the purpose of a choice . Approximately saying, the market of economics i...
