History of Economic Thought: Meaning and Significance
Economics is the scientific study of the ownership, use, and exchange of scarce resources — often shortened to the science of scarcity. Economics is regarded as a social science because it uses scientific methods to build theories that can help explain the behaviour of individuals, groups and organisations.
Economics attempts to explain economic behaviour, which arises when scarce resources are exchanged. In terms of methodology, economists, like other social scientists, are not able to undertake controlled experiments in the way that chemists and biologists are. Hence, economists have to employ different methods, based primarily on observation and deduction and the construction of abstract models. As the social sciences have evolved over the last years, they have become increasingly specialised.
This is true for economics, as witnessed by the development of many different strands of investigation including micro and macro economics, pure and applied economics, and industrial and financial economics.
What links them all is the attempt to understand how and why exchange takes place, and how exchange creates benefits and costs for the participants. Economists use scientific observation and deduction in their investigations. To achieve this they:. Economists describe changes in economic variables, and measure these changes over time. For example, economists describe and measure how interaction in markets determines the prices of such diverse products as motor cars, houses, haircuts, and computer software.
Measurement in economics can take many forms, including measuring absolute and relative quantities and values. When measuring relative values it is common to use index numbers. Economists try to explain the effects, or results, of economic transactions.
Of course, economists also try to explain the short-term movements in prices, and how they also have costs and benefits. Like all scientists, economists develop hypotheses to explain why economic behaviour takes place, and then construct models to test these hypotheses.
For example, economists may propose that price rises are caused by excess demand, and then attempt to construct a model of price that explains how excess demand can raise price. Economists frequently use versions of the demand and supply model to help explain events such as house price trends and movements.
Economic models usually employ graphical and mathematical analysis to help explain and illustrate such economic processes. Models must be tested against the real world, which means gathering statistical data about real events. In this way, a model can be improved and revised when necessary. The ultimate goal of the economist is to predict future behaviour. For example, by using a demand and supply model and by inputting real data about the housing market , economists can show that even a small fall in bank lending can trigger behaviour that leads to a significant fall in house prices in the short run.
The ultimate value of an economic model is that it can accurately predict the onset and the effect of an economic event. The better the model is, the more useful it is in helping economists make predictions. Economists assume that economic events and phenomena do not occur at random, but are determined by underlying and understandable causes. Unlike the pure scientist, economists cannot undertake controlled experiments, so they must test their models in different ways.
Statistical analysis of actual economic data can provide a flow of information from which to build models and test hypotheses. For example, by gathering data about changes in house prices it is possible to deduce factors that cause house prices to go up or down, and by how much. Economists use index numbers to help make comparisons between countries and over time.
Correlation analysis can help determine the strength of particular causal relationships so that strong and weak relationships can be identified. For example, it might be possible to demonstrate that, of all the factors that have contributed to falling house prices, the reduced availability of credit is the single biggest factor.
Professional economists apply their skills of description, analysis, model building, and prediction to generate knowledge and, from this, provide advice to private firms, to governments and other organisations.
In providing advice, the economist will always make an assessment of the other options that could have been chosen. For example, a large petrol refiner and retailer may be faced with a significant rise in the costs of crude oil — should it now raise price? To find out why, see: oligopoly. As a social science, economics attempts to use the principles and methods of science to explain economic behaviour. This involves making positive statements about the economic world. In contrast, normative statements are based on opinion and value judgement.
This statement cannot be tested because it not based on anything testable. If there is an agreed definition of fairness, and it can be measured, then it might be possible to test the effect of the change in house prices on the degree of fairness experienced by a certain identifiable group of people defined as rich. Therefore, this statement is normative, impossible to verify, and based on opinion rather than fact.
Economics is a social science, and, unlike the physical sciences, cannot engage in controlled experimentation to demonstrate how variables are connected. For example, a fall in price is likely to lead to a rise in consumer demand if we assume nothing else changes. Of course, for independent reasons, income could also fall while demand does not rise. The fall in price could have been counteracted by a fall in income.
The ceteris paribus rule, that all other things remain the same, is used whenever attempting to demonstrate the link between economic variables. Without this assumption, positive economics is impossible. Over time the role of the professional economist has broadened.
In recent years much interest has been shown in the interconnections between economics and psychology, and there has been a considerable increase in the popularity of behavioural economics. This is both in terms of the number of Universities offering courses in behavioural economics, and in terms of how public policy makers have turned to this branch of economics, especially in the wake of the financial crisis.
For example, the financial crash of a 20 years ago led to a thorough re-thinking of the nature of financial risk, and to the establishment of better ways to understand why banking systems can fail, as well as develop more effective ways to regulate them. Similarly, the emergence of cryptocurrencies, such as Bitcoin, have forced economists to reassess the nature of money in a globalised world.
Trading relationships between countries, and theories to explain them, have also been put under the spotlight as a result of Brexit. The economic problem. Production possibility frontiers.

Assessing biophysical and socio-economic impacts of climate change on regional avian biodiversity
Lionel Robbins ' Essay , , 2nd ed. Analysis is relative to "accepted solutions of particular problems" based on best modern practice as referenced, especially including the works of Philip Wicksteed , Ludwig von Mises , and other Continental European economists. Robbins disclaims originality but expresses hope to have given expository force on a very few points to some principles "not always clearly stated" , pp. Robbins develops and defends several propositions about the relation of scarcity to economics and of economic theory to science, including the following. The definition of economics above has been described as "central to the arguments presented" that followed in the Essay  and as redefining economics in marginalist terms and thereby "destroy[ing] the view classical economists had of their science. The Essay has been described as different from earlier writings on economic methodology in generating a range of tightly-argued, radical implications from a simple definition, for example in admitting an aspect of behaviour rather than a list of behaviours but not limiting the subject-matter of economics, provided that the influence of scarcity impinges on these pp. The broad behavioural definition is credited for its consistency with the expanding boundaries of economics decades later.

An Essay on the Nature and Significance of Economic Science
Беккер смотрел прямо перед. Вдалеке, метрах в пятистах, на фоне ночного неба возникли силуэты самолетных ангаров. Он подумал, успеет ли такси догнать его на таком расстоянии, и вспомнил, что Сьюзан решала такие задачки в две секунды. Внезапно он почувствовал страх, которого никогда не испытывал. Беккер наклонил голову и открыл дроссель до конца. Веспа шла с предельной скоростью.
А потом медленно скрылась из виду в клубах пара. - Отчаянный парень, - пробормотал Хейл себе под нос. Он знал, что задумал Чатрукьян. Отключение ТРАНСТЕКСТА было логичным шагом в случае возникновения чрезвычайной ситуации, а ведь тот был уверен, что в машину проник вирус. К несчастью, это был самый надежный способ собрать в шифровалке всех сотрудников Отдела обеспечения системной безопасности. После таких экстренных действий на главном коммутаторе раздавался сигнал общей тревоги. Проверку шифровалки службой безопасности Хейл допустить не .
Он снова посмотрел на Джаббу и закрыл. - Танкадо отдал кольцо с умыслом. Мне все равно, думал ли он, что тучный господин побежит к телефону-автомату и позвонит нам, или просто хотел избавиться от этого кольца. Я принял решение.
