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.
Rotemberg held a B.A. in economics (1975) from the University of California, Berkeley, and a Ph.D. in economics (1981) from Princeton University.
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.
The business cycle, also known as the economic cycle or trade cycle, are the fluctuations of gross domestic product (GDP) around its long-term growth trend. The length of a business cycle is the period of time containing a single boom and contraction in sequence. These fluctuations typically involve shifts over time between periods of relatively rapid economic growth and periods of relative stagnation or decline.
Nicholas Gregory Mankiw is an American macroeconomist who is currently the Robert M. Beren Professor of Economics at Harvard University. Mankiw is best known in academia for his work on New Keynesian economics.
Nominal rigidity, also known as price-stickiness or wage-stickiness, is a situation in which a nominal price is resistant to change. Complete nominal rigidity occurs when a price is fixed in nominal terms for a relevant period of time. For example, the price of a particular good might be fixed at $10 per unit for a year. Partial nominal rigidity occurs when a price may vary in nominal terms, but not as much as it would if perfectly flexible. For example, in a regulated market there might be limits to how much a price can change in a given year.
Neo-Keynesian economics is a school of macroeconomic thought that was developed in the post-war period from the writings of John Maynard Keynes. A group of economists, attempted to interpret and formalize Keynes' writings and to synthesize it with the neoclassical models of economics. Their work has become known as the neoclassical synthesis and created the models that formed the core ideas of neo-Keynesian economics. These ideas dominated mainstream economics in the post-war period and formed the mainstream of macroeconomic thought in the 1950s, 1960s and 1970s.
A macroeconomic model is an analytical tool designed to describe the operation of the problems of economy of a country or a region. These models are usually designed to examine the comparative statics and dynamics of aggregate quantities such as the total amount of goods and services produced, total income earned, the level of employment of productive resources, and the level of prices.
Ricardo A. M. R. Reis is a Portuguese economist and the A. W. Phillips professor of economics at the London School of Economics. In a 2013 ranking of young economists by Glenn Ellison, Reis was considered the top economist with a PhD between 1996 and 2004., and in 2016 he won the Germán Bernácer Prize for top European-born economist researching macroeconomics and finance. He writes a weekly op-ed for the Portuguese newspaper Jornal de Notícias and participates frequently in economic debates in Portugal.
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.
Thomas John Sargent is an American economist and the W.R. Berkley Professor of Economics and Business at New York University. He specializes in the fields of macroeconomics, monetary economics, and time series econometrics. As of 2020, he ranks as the 29th most cited economist in the world. He was awarded the Nobel Memorial Prize in Economics in 2011 together with Christopher A. Sims for their "empirical research on cause and effect in the macroeconomy".
In economics, a menu cost is the cost to a firm resulting from changing its prices. The name stems from the cost of restaurants literally printing new menus, but economists use it to refer to the costs of changing nominal prices in general. In this broader definition, menu costs might include updating computer systems, re-tagging items, and hiring consultants to develop new pricing strategies as well as the literal costs of printing menus. More generally, the menu cost can be thought of as resulting from costs of information, decision and implementation resulting in bounded rationality. Because of this expense, firms sometimes do not always change their prices with every change in supply and demand, leading to nominal rigidity. Generally, the effect on the firm of small shifts in price is relatively minor compared to the costs of notifying the public of this new information. Therefore, the firm would rather exist in slight disequilibrium than incur the menu costs.
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.
David Ernest William Laidler is an economist who has been one of the foremost scholars of monetarism. He published major economics journal articles on the topic in the late 1960s and early 1970s. His book, The Demand for Money, was published in four editions from 1969 through 1993, initially setting forth the stability of the relationship between income and the demand for money and later taking into consideration the effects of legal, technological, and institutional changes on the demand for money. The book has been translated into French, Spanish, Italian, Japanese, and Chinese.
Dynamic stochastic general equilibrium modeling is a method in macroeconomics that attempts to explain economic phenomena, such as economic growth and business cycles, and the effects of economic policy, through econometric models based on applied general equilibrium theory and microeconomic principles.
Michael Dean Woodford is an American macroeconomist and monetary theorist who currently teaches at Columbia University.
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.
Paul Davidson is an American macroeconomist who has been one of the leading spokesmen of the American branch of the post-Keynesian school in economics. He is a prolific writer and has actively intervened in important debates on economic policy from a position that is very critical of mainstream economics.
Nobuhiro Kiyotaki FBA is a Japanese economist and the Harold H. Helms '20 Professor of Economics and Banking at Princeton University. He is especially known for proposing several models that provide deeper microeconomic foundations for macroeconomics, some of which play a prominent role in New Keynesian macroeconomics.
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.
The new neoclassical synthesis (NNS) or new synthesis is the fusion of the major, modern macroeconomic schools of thought, new classical and New-Keynesianism, into a consensus 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 economics. It is an important part of the theoretical foundation for the work done by the Federal Reserve and many other central banks.
