The exploration of Adam Smith's "invisible hand" theory is a captivating subject. This theory suggests that individuals, by pursuing their personal interests, inadvertently contribute to the overall economic prosperity of society.

This theory can be illustrated using Kirchoff's laws. Consider each individual as a node in a network. We assume that each individual's incoming and outgoing cashflows are balanced, akin to currents in an electrical circuit. In any loop within this network, the sum of all potential differences will equate to zero. By substituting cash flows for currents and demand and supply for potentials, we infer that no energy, or money, is lost within the system.

When making a business decision, it is crucial to consider not only immediate interests but also long-term implications. For instance, purchasing a residential property in a thriving economy may seem advantageous due to rising property prices. However, upon signing a 30-year lease, one must consider the financial stability over the lease period. The seller's financial situation also plays a significant role in this decision. If the seller is a retired couple with limited income, the property may not come with a matching job opportunity, posing a potential long-term risk.

On the other hand, if the property is purchased from a relocating family with stable, well-paying jobs, their income will cycle back into the economy, providing potential job opportunities even if the buyer loses their current job. A fresh painting is an indication of seller finances.

A short-term decision to increase corporate tax rates may be feasible if they are inelastic. A slight increase in the tax rate may not significantly decrease overall income if corporations are inclined to save on their accounts, or if customers can absorb any price increases. However, the elasticity of the corporation plays a crucial role. Service companies with a recurring flow of transactions and high reinvestment rates, like Amazon, can handle higher income taxes due to their narrow margins. In contrast, manufacturing companies with high fixed costs may struggle with increased taxes, indicating their elasticity to income taxes. Therefore, a unified tax rate may disadvantage larger countries, discouraging manufacturing pushing it overseas, and favoring service industries.

A longer commute is a warning sign when purchasing a property. It may indicate lower wages in the area due to employers having a larger pool of potential employees willing to work shorter hours. This, in turn, reduces the potential for housing payments. However, individuals can offset this by frequently changing jobs or opting for private schools in the city, commuting with their children.

An area with many large mansions suggests a higher prevalence of wealth, which may strain local services and lead to lower-paying service jobs. Wealthy individuals may also be frugal, lowering demand due to the risk of not being able to make an active income again. These factors may create a large variance in property prices.

Data collection can cause significant fluctuations in stock indices. The theory is to collect as much data as needed for a decision, but excessive data can lead to sensitivity to minor issues, causing a ripple effect throughout the system. This can result in recurring declines in pricing and increased system variance, suggesting that irrelevant or easily manipulated data is being considered in pricing decisions.

Lastly, car owners who choose to keep their current vehicle longer instead of replacing it can cause variability in the demand for new cars. This can lead to higher margins, increased insurance needs, and less stable recurring income, affecting industry pricing based on minor, easily influenced factors like minor software bugs or compatibility issues with your cell phone.
