{{Short description|Branch of economics}}'''Normative economics''' (as opposed to [[positive economics]]) is a branch of [[economics]], the objective of which is [[Equity (economics)|fairness]] or what the outcome of the economy or goals of [[public policy]] ''ought to be''.<ref name = "Samuelson">[[Paul A. Samuelson]] and [[William Nordhaus|William D. Nordhaus]] (2004). ''[[Economics (textbook)|Economics]]'', 18th ed., pp. 5-6 & [end] Glossary of Terms, "Normative vs. positive economics."</ref> |

Economists commonly prefer to distinguish normative economics ("what ought to be" in economic matters) from [[positive economics]] ("what is"). Many normative (value) judgments, however, are held conditionally, to be given up if facts or knowledge of facts changes, so that a change of values may be purely scientific.<ref>Stanley Wong (1987). "Positive economics," The ''New Palgrave: A Dictionary of Economics'', v. 3, p. 21.</ref> On the other hand, welfare economist [[Amartya Sen]] distinguishes ''basic (normative) judgements'', which do not depend on such knowledge, from ''nonbasic'' judgments, which do. He finds it interesting to note that "no judgments are demonstrably basic" while some value judgments may be shown to be nonbasic. This leaves open the possibility of fruitful scientific discussion of value judgments.<ref>[[Amartya Sen|Amartya K. Sen]] (1970), ''Collective Choice and Social Welfare'', pp. 61, 63-64).</ref> |
|||
Positive and normative economics are often synthesized in the style of [[practical idealism]]. In this discipline, sometimes called the "art of economics," positive economics is utilized as a practical tool for achieving normative objectives, which often involve policy changes or states of affairs. |
|||
An example of a normative economic statement is as follows: |
|||
::''The price of milk should be $6 a gallon to give dairy farmers a higher living standard and to save the family farm.'' |
|||
This is a normative statement, because it reflects value judgments. This specific statement makes the judgment that farmers deserve a higher living standard and that family farms ought to be saved.<ref name = "Samuelson"/> |
|||
Normative economics predicates itself upon maximizing both an agents social and political utility, recognized as "aggregating interests". |
|||
Subfields of normative economics include social choice theory, cooperative game theory, and mechanism design. |
|||
Over time, divergence in normative economics has given rise to various economic schools of thought as various intellectuals and economists have debated over the effectiveness and morality of various economic systems. In the modern era, these have been broadly classified into "left" and "right" leaning patterns. Left-leaning economic thought is based on [[Marxism|Marxist]] economic theory and advocates a change to a [[communist]] economy wherein workers own the means of production and goods are distributed based on individual needs, either through government intervention in the economy in the case of [[socialism]] or through direct abolition of the state; the origins of left-wing economics are ancient, with key values such as [[Land reform|land reform]] advocated for by [[Tiberius Gracchus]] in the 2nd century BC, although modern socialism and communism draws largely from [[Marxian economics]] theorised in the 19th century. On the other side of the spectrum, right-leaning (''liberal'') economic thought tends to advocate for minimal government intervention in the economy. [[Liberalism]], largely developed by the Dutch and British, is a right-leaning economic ideology that calls for market factors such as [[supply and demand]] to determine production and consumption of goods within a [[capitalism|capitalist]] economic system. Liberal normative economic philosophy is attributed principally to British thinker Adam Smith. In ''The Wealth of Nations'', Adam Smith advocates a ''[[Laissez-faire|laissez-faire]] approach'', arguing markets are best when they are controlled naturally by private consumers and businesses, with no or minimal market controls nor government intervention. Historically, a principal antithesis to capitalism was [[Marxism-Leninism]], an application of Marxist principles through political and economic restructuring which emerged spreading to corners of the globe, it advocates for state-controlled determination of production and consumption. Communist theory is widely attributed to Karl Marx and Friedrich Engels. Academic debate is still open over the merit of state involvement in the economy and its resulting political and social implications, with substantial improvements in physical quality of life nonetheless observed in socialised systems.<ref>{{Cite journal |title=Economic Development, Political-Economic System, and the Physical Quality of Life |journal=[[Journal of Public Health Policy]] |url=https://www.jstor.org/stable/3342145?seq=1 |last=Cereseto |first=Shirley |via=JSTOR |last2=Waitzkin |first2=Howard |year=1988 |jstor=3342145}}</ref> |

Some earlier technical problems posed in [[welfare economics]] and the [[theory of justice]] have been sufficiently addressed as to leave room for consideration of proposals in applied fields such as [[resource allocation]], [[public policy]], social indicators, and [[income inequality metrics|inequality and poverty measurement]].<ref>Marc Fleurbaey (2008).
