Positive versus Normative Statements

The best way to understand positive and normative statements is to look at some examples.

  1. “Higher taxes on cigarettes will reduce smoking.” Positive
  2. “This means that we should increase taxes on cigarettes.” Normative
  3. “No, cigarette taxes are already too high.” Normative

Remember, positive statements can be tested!

Here are some tools to help you with the supply and demand and price control problems:

Reasons to shift Demand Curve:

  1. Change in tastes and preference of the consumer.
  2. Change in income; normal or inferior good.
  3. Change in the prices of other goods; complements or substitutes in consumption.
  4. Change in the number of consumers (population).

Reasons to shift the Supply Curve:

  1. Change in the costs of production i.e. the cost of inputs (parts) of the good, better technology, taxes.
  2. Change in the number of producers (size of the market).
  3. Change in prices of other goods. i.e. substitutes or complements in production.
  4. Changes in nature; expectations.
