Economic growth is the increase in the amount of the goods and services produced by an economy over time. It is conventionally measured as the percent rate of increase in real gross domestic product, or real GDP. Growth is usually calculated in real terms, i.e. inflation-adjusted terms, in order to net out the effect of inflation on the price of the goods and services produced. In economics, "economic growth" or "economic growth theory" typically refers to growth of potential output, i.e., production at "full employment," which is caused by growth in aggregate demand or observed output.
As an area of study, economic growth is generally distinguished from development economics. The former is primarily the study of how countries can advance their economies. The latter is the study of the economic aspects of the development process in low-income countries.
As economic growth is measured as the annual percent change of gross domestic product (GDP), it has all the advantages and drawbacks of that measure.
Paul Robin Krugman ( /ˈkruːɡmən/; born February 28, 1953) is an American economist, Professor of Economics and International Affairs at the Woodrow Wilson School of Public and International Affairs at Princeton University, Centenary Professor at the London School of Economics, and an op-ed columnist for The New York Times. In 2008, Krugman won the Sveriges Riksbank Prize in Economic Sciences (informally the Nobel Prize in Economics) for his contributions to New Trade Theory and New Economic Geography. According to the Nobel Prize Committee, the prize was given for Krugman's work explaining the patterns of international trade and the geographic concentration of wealth, by examining the impact of economies of scale and of consumer preferences for diverse goods and services.
Krugman is known in academia for his work on international economics (including trade theory, economic geography, and international finance),liquidity traps and currency crises. He is the 17th most widely cited economist in the world today and is ranked among the most influential academic thinkers in the US.
Andrew Michael Spence (born November 7, 1943) is an American economist and recipient of the 2001 Nobel Memorial Prize in Economic Sciences, along with George A. Akerlof and Joseph E. Stiglitz, for their work on the dynamics of information flows and market development. He conducted this research while at Harvard University. In the current technological environment—with ever more abundant information flows about market development, prices, profit margins, investment instruments and rates of return—their work is more relevant than ever.
Michael Spence is probably most famous for his job-market signaling model, which essentially triggered the enormous volume of literature in this branch of contract theory. In this model, employees signal their respective skills to employers by acquiring a certain degree of education, which is costly to them. Employers will pay higher wages to more educated employees, because they know that the proportion of employees with high abilities is higher among the educated ones, as it is less costly for them to acquire education than it is for employees with low abilities. For the model to work, it is not even necessary for education to have any intrinsic value if it can convey information about the sender (employee) to the recipient (employer) and if the signal is costly.
Mark Thornton is an American economist of the Austrian School. Thornton has been described by the Advocates for Self-Government as "one of America's experts on the economics of illegal drugs." Thornton has written extensively on that topic, as well as on the economics of the American Civil War, economic bubbles, and public finance. He successfully predicted the housing bubble, the top in home builder stocks, the bust in housing and the world economic crisis.
Thornton received his B.S. from St. Bonaventure University (1982), and his Ph.D. from Auburn University (1989). Thornton taught economics at Auburn University for a number of years, additionally serving as founding faculty advisor for the Auburn University Libertarians. He also served on the faculty of Columbus State University, and is now a senior fellow and resident faculty member at the Ludwig von Mises Institute. He is currently the Book Review Editor for the Quarterly Journal of Austrian Economics.
Libertarian organizations including the Independent Institute, the Cato Institute, and the Mises Institute have published Thornton's writings on drug prohibition and prohibition in general. Thornton contributed a chapter to Jefferson Fish's book How to Legalize Drugs. He has also been interviewed on the topic of prohibition by members of the mainstream press. His research and publications are the basis of the Iron Law of Prohibition which states that the enforcement of prohibition increases the potency and danger of consuming illegal drugs. Thornton's first book, The Economics of Prohibition, was praised by Murray Rothbard, who declared:
