The GlasswasherParts data breach letter shows how both economic and psychological ideas show up in real world situations. From an economic perspective, rational choice theory fits because the company is taking deliberate steps to minimize losses and protect its customers. They weighed the risks and acted accordingly. Keynesian economic theory also applies since the company is actively trying to stabilize trust and confidence among its customers, similar to how governments use spending to maintain economic stability. On the psychology side, prospect theory explains why customers might overreact to potential losses, even if their info hasn’t been misused yet. Social trust theory comes into play because the letter’s tone and instructions are designed to keep customers feeling safe and confident in the company. It is a good example of how business decisions have to consider both human behavior and economic thinking.
