Economics of security is the study of how people use money to protect themselves, their families, and their property. It looks at the different costs associated with protection and the benefits of having a secure environment. For example, people might need to pay money to install alarms, cameras, or other security devices to help protect their homes and businesses. The cost of buying and installing these security devices, plus the cost of monitoring them, are all costs of security that need to be considered. The benefits of having these security devices can include feeling safer, reducing the chances of being burglarized, and having peace of mind.
