Economics is a social science that studies the production, distribution, and consumption of goods and services.
Keynesian economics are the various macroeconomic theories and models of how aggregate demand strongly influences economic output and inflation. In the Keynesian view, aggregate demand does not necessarily equal the productive capacity of the economy. It is influenced by a host of factors that sometimes behave erratically and impact production, employment, and inflation.
Microeconomics is a branch of economics that studies the behavior of individuals and firms in making decisions regarding the allocation of scarce resources and the interactions among these individuals and firms. Microeconomics focuses on the study of individual markets, sectors, or industries as opposed to the national economy as a whole, which is studied in macroeconomics.
Macroeconomics is a branch of economics that deals with the performance, structure, behavior, and decision-making of an economy as a whole. This includes regional, national, and global economies. Macroeconomists study topics such as output/GDP and national income, unemployment, price indices and inflation, consumption, saving, investment, energy, international trade, and international finance.
In economics, stagflation or recession-inflation is a situation in which the inflation rate is high or increasing, the economic growth rate slows, and unemployment remains steadily high. It presents a dilemma for economic policy, since actions intended to lower inflation may exacerbate unemployment.
In economics, inflation is a general increase in the prices of goods and services in an economy. This is usually measured using the consumer price index (CPI). When the general price level rises, each unit of currency buys fewer goods and services; consequently, inflation corresponds to a reduction in the purchasing power of money. The opposite of CPI inflation is deflation, a decrease in the general price level of goods and services. The common measure of inflation is the inflation rate, the annualized percentage change in a general price index. As prices faced by households do not all increase at the same rate, the consumer price index (CPI) is often used for this purpose.
In economics, deflation is a decrease in the general price level of goods and services. Deflation occurs when the inflation rate falls below 0%. Inflation reduces the value of currency over time, but deflation increases it. This allows more goods and services to be bought than before with the same amount of currency. Deflation is distinct from disinflation, a slowdown in the inflation rate; i.e., when inflation declines to a lower rate but is still positive.

Classical economics, classical political economy, or Smithian economics is a school of thought in political economy that flourished, primarily in Britain, in the late 18th and early-to-mid-19th century. Its main thinkers are held to be Adam Smith, Jean-Baptiste Say, David Ricardo, Thomas Robert Malthus, and John Stuart Mill. These economists produced a theory of market economies as largely self-regulating systems, governed by natural laws of production and exchange.
Human Action: A Treatise on Economics is a work by the Austrian economist and philosopher Ludwig von Mises. Widely considered Mises' magnum opus, it presents the case for laissez-faire capitalism based on praxeology, his method to understand the structure of human decision-making. Mises rejected positivism within economics, and defended an a priori foundation for praxeology, as well as methodological individualism and laws of self-evident certainty. Mises argues that the free-market economy not only outdistances any government-planned system, but ultimately serves as the foundation of civilization itself.
Allocative efficiency is a state of the economy in which production is aligned with the preferences of consumers and producers; in particular, the set of outputs is chosen so as to maximize the social welfare of society. This is achieved if every produced good or service has a marginal benefit equal to the marginal cost of production.
Articles in economics journals are usually classified according to JEL classification codes, which derive from the Journal of Economic Literature. The JEL is published quarterly by the American Economic Association (AEA) and contains survey articles and information on recently published books and dissertations. The AEA maintains EconLit, a searchable data base of citations for articles, books, reviews, dissertations, and working papers classified by JEL codes for the years from 1969. A recent addition to EconLit is indexing of economics journal articles from 1886 to 1968 parallel to the print series Index of Economic Articles.
Arnold Carl Harberger is an American economist. His approach to the teaching and practice of economics is to emphasize the use of analytical tools that are directly applicable to real-world issues. His influence on academic economics is reflected in part by the widespread use of the term "Harberger triangle" to refer to the standard graphical depiction of the efficiency cost of distortions of competitive equilibrium. His influence on the practice of economic policy is manifested by the high positions attained by his followers in national agencies such as central banks and ministries of finance, and in international agencies such as the World Bank.
Modern monetary theory or modern money theory (MMT) is a heterodox macroeconomic theory that describes currency as a public monopoly and unemployment as evidence that a currency monopolist is overly restricting the supply of the financial assets needed to pay taxes and satisfy savings desires. According to MMT, governments do not need to worry about accumulating debt since they can create new money by using fiscal policy in order to pay interest. MMT argues that the primary risk once the economy reaches full employment is inflation, which acts as the only constraint on spending. MMT also argues that inflation can be addressed by increasing taxes on everyone to reduce the spending capacity of the private sector.

The history of economic thought is the study of the philosophies of the different thinkers and theories in the subjects that later became political economy and economics, from the ancient world to the present day in the 21st century. This field encompasses many disparate schools of economic thought. Ancient Greek writers such as the philosopher Aristotle examined ideas about the art of wealth acquisition, and questioned whether property is best left in private or public hands. In the Middle Ages, Thomas Aquinas argued that it was a moral obligation of businesses to sell goods at a just price.
The neoclassical synthesis (NCS), neoclassical–Keynesian synthesis, or just neo-Keynesianism was a neoclassical economics academic movement and paradigm in economics that worked towards reconciling the macroeconomic thought of John Maynard Keynes in his book The General Theory of Employment, Interest and Money (1936). It was formulated most notably by John Hicks (1937), Franco Modigliani (1944), and Paul Samuelson (1948), who dominated economics in the post-war period and formed the mainstream of macroeconomic thought in the 1950s, 60s, and 70s.
Macroeconomic theory has its origins in the study of business cycles and monetary theory. In general, early theorists believed monetary factors could not affect real factors such as real output. John Maynard Keynes attacked some of these "classical" theories and produced a general theory that described the whole economy in terms of aggregates rather than individual, microeconomic parts. Attempting to explain unemployment and recessions, he noticed the tendency for people and businesses to hoard cash and avoid investment during a recession. He argued that this invalidated the assumptions of classical economists who thought that markets always clear, leaving no surplus of goods and no willing labor left idle.
Throughout modern history, a variety of perspectives on capitalism have evolved based on different schools of thought.
