Information asymmetry happens when buyers and sellers have different levels of information, leading to adverse selection in the market. Adverse selection occurs when one party, either the buyer or the seller, has hidden information about the product and makes buying or selling decisions based on that information. For example, in the used car market, buyers cannot know everything about the cars and cannot fully trust them. Because of this, they often try to buy used cars at lower prices to evaluate their quality. To make buyers feel more confident, sellers might promise to repair the car free of charge if it breaks within a year after purchase, protecting themselves against adverse selection. A successful transaction depends on strategies that align with the market’s specific characteristics. - Joseph’s “just my thoughts”
British anthropologist Robin Dunbar was certain that primate cerebral neocortical capacity determines the number of social relations. He definitively established the limit of human relationships at 100 to 230 people. The average value of 150 people is known as Dunbar's number. In the world of chimpanzees, 30 is the absolute maximum. However, fewer than 12 people in the world can sympathize with me. My best friend is now reduced to 3 or 4. The relationship quantity decreases to the square root value and increases to the square value. Three or four of my best friends will eventually connect with people from all over the world. This is the same principle as when one or two virus-infected people infect the world. Focus on your best friend. - Joseph’s “just my thoughts”
