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.
When the price level falls, consumers are wealthier, a condition which induces more consumer spending. Thus, a drop in the price level induces consumers to spend more, thereby increasing the aggregate demand. The second reason for the downward slope of the aggregate demand curve is Keynes's interest-rate effect. Recall that the quantity of money demanded is dependent upon the price level. That is, a high price level means that it takes a relatively large amount of currency to make purchases.
