  2. Engel curve - Wikipedia

    en.wikipedia.org/wiki/Engel_curve

    For normal goods, the Engel curve has a positive gradient. That is, as income increases, the quantity demanded increases. That is, as income increases, the quantity demanded increases. Amongst normal goods, there are two possibilities.

  3. Positive and normative economics - Wikipedia

    en.wikipedia.org/wiki/Positive_and_normative...

    Positive economics as such avoids economic value judgments. For example, a positive economic theory might describe how money supply growth affects inflation, but it does not provide any instruction on what policy ought to be followed. An example of a normative economic statement is as follows:

  4. Normal good - Wikipedia

    en.wikipedia.org/wiki/Normal_good

    In economics, a normal good is a type of a good which experiences an increase in demand due to an increase in income, unlike inferior goods, for which the opposite is observed. When there is an increase in a person's income, for example due to a wage rise, a good for which the demand rises due to the wage increase, is referred as a normal good.

  5. Lagrange multiplier - Wikipedia

    en.wikipedia.org/wiki/Lagrange_multiplier

    For example, in economics the optimal profit to a player is calculated subject to a constrained space of actions, where a Lagrange multiplier is the change in the optimal value of the objective function (profit) due to the relaxation of a given constraint (e.g. through a change in income); in such a context is the marginal cost of the ...

  6. Contract curve - Wikipedia

    en.wikipedia.org/wiki/Contract_curve

    In the case of two goods and two individuals, the contract curve can be found as follows. Here refers to the final amount of good 2 allocated to person 1, etc., and refer to the final levels of utility experienced by person 1 and person 2 respectively, refers to the level of utility that person 2 would receive from the initial allocation without trading at all, and and refer to the fixed total ...

  7. Lorenz curve - Wikipedia

    en.wikipedia.org/wiki/Lorenz_curve

    The Lorenz curve is invariant under positive scaling. If X is a random variable, for any positive number c the random variable c X has the same Lorenz curve as X. The Lorenz curve is flipped twice, once about F = 0.5 and once about L = 0.5, by negation. If X is a random variable with Lorenz curve L X (F), then −X has the Lorenz curve:

  8. Phillips curve - Wikipedia

    en.wikipedia.org/wiki/Phillips_curve

    In these macroeconomic models with sticky prices, there is a positive relation between the rate of inflation and the level of demand, and therefore a negative relation between the rate of inflation and the rate of unemployment. This relationship is often called the "New Keynesian Phillips curve".

  9. Procyclical and countercyclical variables - Wikipedia

    en.wikipedia.org/wiki/Procyclical_and...

    Keynesian economics advocates the use of automatic and discretionary countercyclical policies to lessen the impact of the business cycle. One example of an automatically countercyclical fiscal policy is progressive taxation. By taxing a larger proportion of income when the economy expands, a progressive tax tends to decrease demand when the ...
