Economists engage in two distinct, but related activities.
Economists frequently distinguish between 'positive' and 'normative' economics. Positive economics is concerned with the development and testing of positive statements about the world that are objective and verifiable. Normative statements derive from an opinion or a point of view. Thus the words 'should', 'ought to' or 'it is better to' frequently occur.
Whenever you are reading articles on current affairs it is important to be able to distinguish between objective and subjective statements. Positive statements are objective statements that can be tested, amended or rejected by referring to the available evidence. Positive economics deals with objective explanation and the testing and rejection of theories. For example:. A value judgement is a subjective statement of opinion rather than a fact that can be tested by looking at the available evidence. Normative statements are subjective statements — i. Focusing on the evidence is called adopting an empirical approach — evidence-based work is becoming more and more important in shaping different government policies and how much funding to give to each.

In the social sciences and philosophy , a positive or descriptive statement concerns what "is", "was", or "will be", and contains no indication of approval or disapproval what should be. Positive statements are thus the opposite of normative statements. Positive statements are based on empirical evidence. For examples, "An increase in taxation will result in less consumption" and "A fall in supply of petrol will lead to an increase in its price". However, positive statements can be factually incorrect: "The moon is made of green cheese" is empirically false, but is still a positive statement, as it is a statement about what is, not what should be.

Reason as the Source of Knowledge For medieval men, the existence of a personal and acting God was beyond any doubt. They were convinced that God intervenes into and interferes with the course of the world. The acting of God was a main factor for the explanation of natural phenomena. But with the passing of time, the understanding of nature improved and more and more phenomena could be explained by appeal to reason only and without recourse to actions of God. It became the general opinion that natural phenomena are subject to invariable natural laws. This modern philosophy saw nature as a mechanic construction.
Normative economics as opposed to positive economics is a part of economics whose objective is fairness or what the outcome of the economy or goals of public policy ought to be. 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. 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. Positive and normative economics are often synthesized in the style of practical idealism.
It is common knowledge that economists often disagree. These differences result from different assumptions or hypotheses about how things are or from different views about how things ought to be. Example: An increase in the minimum wage increases unemployment among teenagers.
Хейл не мог поверить, что Стратмор согласился упустить такую возможность: ведь черный ход был величайшим шансом в его жизни. Хейлом овладела паника: повсюду, куда бы он ни посмотрел, ему мерещился ствол беретты Стратмора. Он шарахался из стороны в сторону, не выпуская Сьюзан из рук, стараясь не дать Стратмору возможности выстрелить. Движимый страхом, он поволок Сьюзан к лестнице. Через несколько минут включат свет, все двери распахнутся, и в шифровалку ворвется полицейская команда особого назначения. - Мне больно! - задыхаясь, крикнула Сьюзан. Она судорожно ловила ртом воздух, извиваясь в руках Хейла.
А вы пробовали сделать ему искусственное дыхание? - предположил Беккер. - Нет. Мы к нему не прикасались.
