New Keynesian economics. New Keynesian economics is a school of contemporary 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. Origins[edit] Significant early contributions to New Keynesian theory were compiled in 1991 by editors N. Gregory Mankiw and David Romer in New Keynesian Economics, volumes 1 and 2.[2] The papers in these volumes focused mostly on microfoundations, that is, microeconomic ingredients that could produce Keynesian macroeconomic effects, and did not yet attempt to construct complete macroeconomic models. Microfoundations of price stickiness[edit] As Mankiw describes, a firm that lowers its prices because of a decrease in the money supply will be raising the real income of the customers of that product.
Other sources of price stickiness include: Other microeconomic ingredients[edit] New Keynesian DSGE models[edit] See also[edit]
Israel Hayom. How Ron Paul Became A Revolution. One World, Rival Theories - By Jack Snyder. The U.S. government has endured several painful rounds of scrutiny as it tries to figure out what went wrong on Sept. 11, 2001. The intelligence community faces radical restructuring; the military has made a sharp pivot to face a new enemy; and a vast new federal agency has blossomed to coordinate homeland security. But did September 11 signal a failure of theory on par with the failures of intelligence and policy? Familiar theories about how the world works still dominate academic debate. Instead of radical change, academia has adjusted existing theories to meet new realities. Has this approach succeeded?
Does international relations theory still have something to tell policymakers? Six years ago, political scientist Stephen M. The influence of these intellectual constructs extends far beyond university classrooms and tenure committees. Each theory offers a filter for looking at a complicated picture. In liberal democracies, realism is the theory that everyone loves to hate. E-Diplomacy map shows which leaders talk to each other on Twitter. We all know that Barack Obama (or at least, his staff), is on Twitter, sending out messages under @barackobama. Turns out, so are lots of world leaders (or rather, their surrogates). There’s Toomas Hendrik Ilves, the president of Estonia. There’s Dmitry Medvedev, the prime minister of Russia. So are the leaders of Canada, Mexico, Brazil and Rwanda.
Heck, even Ayatollah Ali Khamenei, the Supreme Leader of Iran, is on Twitter: @khamenei_ir. What does this all mean? No one is quite sure yet, although there are some folks like Matthias Leufkens, formerly of the World Economic Forum, that have been examining "Twitplomacy" for a few years now. But this week, some journalists over at the Agence France Presse have put together a neat interactive online tool, called E-Diplomacy, that shows which countries follow which others, how much social discussion is going on between various countries, diplomats, and world thinkers.
