Investopedia explains 'Utility'
1. A consumer's utility is hard to measure. However, we can determine it indirectly with consumer behavior theories, which assume that consumers will strive to maximize their utility. Utility is a concept that was introduced by Daniel Bernoulli. He believed that for the usual person, utility increased with wealth but at a decreasing rate.
2. Since consumer demand for utilities does not change dramatically with a change in price, these companies are regulated by the state or provincial and federal governments.
