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”
Vaccines have allowed people to travel worldwide. Migration and population density are benefits of vaccines. When vaccines failed to curb the epidemic, the “space” ultimately addressed the epidemic. This history is why maintaining “social distance” is essential. Hunting requires one million square meters to secure a person’s livelihood, but urbanization restricts many individuals from accessing such vast spaces. On the other hand, if agriculture can address livelihood needs with just 500 square meters, and its efficiency can increase by 2,000 times, then the perspective on the epidemic reveals insights about civilization. - Joseph’s “just my thoughts”
