Verified step by step guidance

1. Understand the concept of willingness to pay (WTP), which represents the maximum amount a consumer is ready to pay for a good or service based on their preferences and perceived value.
2. Recognize that consumer surplus is the difference between the consumer's willingness to pay and the actual market price they pay for the good.
3. Identify that the producer's cost and government-imposed taxes affect the supply side and market price but do not directly influence the initial decision of the consumer to consider purchasing the good.
4. Focus on the consumer's individual willingness to pay as the primary factor because it determines whether the consumer values the good enough to buy it at the given price.
5. Conclude that the first factor affecting a consumer's decision to purchase is their own willingness to pay, as it sets the baseline for whether the transaction is beneficial from the consumer's perspective.
