New Keynesian economics is a school of macroeconomics that strives to provide microeconomic foundations for Keynesian economics. It developed partly as a response to criticisms of Keynesian macroeconomics by adherents of new classical macroeconomics.
Robert Emerson Lucas Jr. is an American economist at the University of Chicago, where he is currently the John Dewey Distinguished Service Professor Emeritus in Economics and the College. Widely regarded as the central figure in the development of the new classical approach to macroeconomics, he received the Nobel Prize in Economics in 1995 "for having developed and applied the hypothesis of rational expectations, and thereby having transformed macroeconomic analysis and deepened our understanding of economic policy". He has been characterized by N. Gregory Mankiw as "the most influential macroeconomist of the last quarter of the 20th century." As of 2020, he ranks as the 11th most cited economist in the world.
Supply-side economics is a macroeconomic theory that postulates economic growth can be most effectively fostered by lowering taxes, decreasing regulation, and allowing free trade. According to supply-side economics, consumers will benefit from greater supplies of goods and services at lower prices, and employment will increase. Supply-side fiscal policies are designed to increase aggregate supply, as opposed to aggregate demand, thereby expanding output and employment while lowering prices. Such policies are of several general varieties:
- Investments in human capital, such as education, healthcare, and encouraging the transfer of technologies and business processes, to improve productivity. Encouraging globalized free trade via containerization is a major recent example.
- Tax reduction, to provide incentives to work, invest and take risks. Lowering income tax rates and eliminating or lowering tariffs are examples of such policies.
- Investments in new capital equipment and research and development (R&D), to further improve productivity. Allowing businesses to depreciate capital equipment more rapidly gives them an immediate financial incentive to invest in such equipment.
- Reduction in government regulations, to encourage business formation and expansion.

John Brian Taylor is the Mary and Robert Raymond Professor of Economics at Stanford University, and the George P. Shultz Senior Fellow in Economics at Stanford University's Hoover Institution.
Mainstream economics is the body of knowledge, theories, and models of economics, as taught by universities worldwide, that are generally accepted by economists as a basis for discussion. Also known as orthodox economics, it can be contrasted to heterodox economics, which encompasses various schools or approaches that are only accepted by a minority of economists.
Harvey Sheldon Rosen is an American economist and academic. Prior to his retirement and subsequent appointment as Emeritus Professor in 2019, Rosen was the John L. Weinberg Professor of Economics and Business Policy at Princeton University, and former chairperson of the Council of Economic Advisers. His research focuses on public finance. Harvard University economist and former Council of Economic Advisers chairman Greg Mankiw credits Rosen as one of four mentors who taught him how to practice economics, along with Alan Blinder, Larry Summers, and Stanley Fischer.
Alberto Francesco Alesina was an Italian political economist. Described as one of the leading political economists of his generation, he published many influential works in both the economics and political science research literature.
Dynamic stochastic general equilibrium modeling is a macroeconomic method which is often employed by monetary and fiscal authorities for policy analysis, explaining historical time-series data, as well as future forecasting purposes. DSGE econometric modelling applies general equilibrium theory and microeconomic principles in a tractable manner to postulate economic phenomena, such as economic growth and business cycles, as well as policy effects and market shocks.
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.
New classical macroeconomics, sometimes simply called new classical economics, is a school of thought in macroeconomics that builds its analysis entirely on a neoclassical framework. Specifically, it emphasizes the importance of rigorous foundations based on microeconomics, especially rational expectations.
Jordi Galí is a Spanish macroeconomist who is regarded as one of the main figures in New Keynesian macroeconomics today. He is currently the director of the Centre de Recerca en Economia Internacional at Universitat Pompeu Fabra and a Research Professor at the Barcelona Graduate School of Economics. After obtaining his doctorate from MIT in 1989 under the supervision of Olivier Blanchard, he held faculty positions at Columbia University and New York University before moving to Barcelona.
Christina Duckworth Romer is the Class of 1957 Garff B. Wilson Professor of Economics at the University of California, Berkeley and a former chair of the Council of Economic Advisers in the Obama administration. She resigned from her role on the Council of Economic Advisers on September 3, 2010.

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.
Julio Jacobo Rotemberg was an Argentine/American economist at Harvard Business School. He was known for his collaboration with Michael Woodford on the first New Keynesian DSGE model, especially on monopolistic competition. He was also known for an alternative model of sticky prices.
In economics, coordination failure is a concept that can explain recessions through the failure of firms and other price setters to coordinate. In an economic system with multiple equilibria, coordination failure occurs when a group of firms could achieve a more desirable equilibrium but fail to because they do not coordinate their decision making. Coordination failure can result in a self-fulfilling prophecy. For example, if one firm decides a recession is imminent and fires its workers, other firms might lose demand from the lay-offs and respond by firing their own workers leading to a recession at a new equilibrium. Coordination failure can also be associated with sunspot equilibria and animal spirits.
The new neoclassical synthesis (NNS), which is now generally referred to as New Keynesian economics, and occasionally as the New Consensus, is the fusion of the major, modern macroeconomic schools of thought – new classical macroeconomics/real business cycle theory and early New Keynesian economics – into a consensus view on the best way to explain short-run fluctuations in the economy. This new synthesis is analogous to the neoclassical synthesis that combined neoclassical economics with Keynesian macroeconomics. The new synthesis provides the theoretical foundation for much of contemporary mainstream macroeconomics. It is an important part of the theoretical foundation for the work done by the Federal Reserve and many other central banks.
