Economic Indicators. Real World Economies. Economy Economics. Key Takeaways Economics is generally regarded as a social science, which revolves around the relationships between individuals and societies. Critics argue that economics is not a science due to a lack of testable hypotheses and ability to achieve consensus. Article Sources.

What Is Experimental Economics? Experimental economics studies human behavior in a controlled setting, to test economic theories by seeing how people respond to incentives. What Is Political Economy? Political economy is a branch of the social sciences that focuses on the interrelationships among individuals, governments, and public policy. Ceteris Paribus Ceteris paribus, a Latin phrase meaning "all else being equal," helps isolate multiple independent variables affecting a dependent variable.
Primary focus areas are unemployment, inflation, economic growth, and monetary and fiscal policy. The discipline of economics evolved in the midth century through the combination of political economy, social science and philosophy and gained entrenchment with the increased scrutiny of the asymmetric financial and welfare distribution attributed to sovereign rule.
Early writings are attributable to Jeremy Bentham, David Ricardo, John Stuart Mill and his son John Mill and are focused on human welfare and benefits rather than capitalism and free markets. Founders of Economics : John Stuart Mill, along with David Ricardo, Jeremy Bentham and other political and social philosophers of the mid-nineteenth century are credited with the founding of the social-political theory that has evolved to be the discipline of economics.
As in other social sciences, economics does incorporate mathematics in the theoretical and analytics framework of the discipline. Formal economic modeling began in the 19th century with the use of differential calculus to represent and explain economic behavior, such as utility maximization, an early economic application of mathematical optimization in microeconomics. Economics utilizes mathematics to assess the relationships between economic actors in environments in which resources are finite.
Economic theory and analysis may be applied throughout society, including business, finance, health care, and government. The underlying components of economic theory can also be applied to variety of other subjects, such as crime, education, the family, law, politics, religion, social institutions, war, and science.

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.

Rescues economic theory from mathematics, restoring a realistic approach to human motivations and behavior in the real world economy. Description Economics as a Social Science: An Approach to Nonautistic Theory, a highly readable critique of economic theory based on a wide range of research, endeavors to restore economics to its proper role as a social science.
He transcends the narrow traditional conceptions of greed and rationality and more generally highlights the inherent limitations of economics.
He draws our attention beyond the exchange transactions in the market to the widely neglected phenomena of gift, coercion and preying. Internal consistency, he argues, is not a sufficient condition for good theory.
