After those first series of shots, you should receive a booster shot every 10 years. If you step on a nail or suffer a wound that is deep and dirty, and haven't had a tetanus shot in the past 10 years, you need help fast. Seek medical attention immediately and rinse the wound with tap water. Do not cleanse with soap or apply antiseptic to a deep wound.
An increase in the price will reduce consumer surplus, while a decrease in the price will increase consumer surplus. Below are two scenarios that illustrate how changes in price can affect consumers' surplus. It is important to note that any shift from the good's pareto optimal price will result in a decrease in the total economic surplus. The total economic surplus equals the sum of the consumer and producer surpluses.
Understand that a consumer's responses to a price change differ depending upon the nature of a good, viz. a normal good, inferior good or a neutral good. Accordingly we have different types of price effects such as positive, negative and zero price effects. These types of price effect corresponding to consumer's responses for different nature of goods are summarized in chart.1: Thus, a price effect is positive in case of normal goods. There is an inverse relationship between price and quantity demanded. It is negative in case of inferior goods (including Giffen goods) where we find a direct relationship between price and quantity demanded.
