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.
Paul Robin Krugman is an American economist who is the Distinguished Professor of Economics at the Graduate Center of the City University of New York and a columnist for The New York Times. In 2008, Krugman was the sole winner of the Nobel Memorial Prize in Economic Sciences for his contributions to new trade theory and new economic geography. The Prize Committee cited Krugman's work explaining the patterns of international trade and the geographic distribution of economic activity, by examining the effects of economies of scale and of consumer preferences for diverse goods and services.
A liquidity trap is a situation, described in Keynesian economics, in which, "after the rate of interest has fallen to a certain level, liquidity preference may become virtually absolute in the sense that almost everyone prefers holding cash rather than holding a debt which yields so low a rate of interest."
A price ceiling is a government- or group-imposed price control, or limit, on how high a price is charged for a product, commodity, or service. Governments use price ceilings to protect consumers from conditions that could make commodities prohibitively expensive. Such conditions can occur during periods of high inflation, in the event of an investment bubble, or in the event of monopoly ownership of a product, all of which can cause problems if imposed for a long period without controlled rationing, leading to shortages. Further problems can occur if a government sets unrealistic price ceilings, causing business failures, stock crashes, or even economic crises. On the other hand, price ceilings give a government to the power to prevent corporations from price gouging or otherwise setting prices that create negative outcomes for the government's society.

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 pay interest by printing money. 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 controlled by increasing taxes on everyone, to reduce the spending capacity of the private sector.

The Return of Depression Economics and the Crisis of 2008 is a non-fiction book by American economist and Nobel Prize winner Paul Krugman, written in response to growing socio-political discourse on the return of economic conditions similar to The Great Depression. The book was first published in 1999 and later updated in 2008 following his Nobel Prize of Economics. The Return of Depression Economics uses Keynesian analysis of past economics crisis, drawing parallels between the 2008 financial crisis and the Great Depression. Krugman challenges orthodox economic notions of restricted government spending, deregulation of markets and the efficient market hypothesis. Krugman offers policy recommendations for the prevention of future financial crises and suggests that policymakers "relearn the lessons our grandfathers were taught by the Great Depression" and prop up spending and enable broader access to credit.

Following the COVID-19 pandemic in 2020, a worldwide surge in inflation began in mid-2021 and lasted until mid-2022. Many countries saw their highest inflation rates in decades. It has been attributed to various causes, including pandemic-related economic dislocation, supply chain disruptions, the fiscal and monetary stimulus provided in 2020 and 2021 by governments and central banks around the world in response to the pandemic, and price gouging. Preexisting factors that may have contributed to the surge included housing shortages, climate impacts, and government budget deficits have also been cited as factors. Recovery in demand from the COVID-19 recession had, by 2021, revealed significant supply shortages across many business and consumer economic sectors. The inflation rate in the United States and the eurozone peaked in the second half of 2022 and sharply declined in 2023. Despite a worldwide decline, some economists have speculated that higher consumer prices are unlikely to return pre-pandemic levels and may remain elevated. Economists state that for prices to return to pre-pandemic levels a deflationary period would be required, which is usually associated with recession. However, as of August 2024, some average consumer prices in the United States have fallen as consumers have reduced spending while the economy continues to grow.
Greedflation, or sellers' inflation, describes inflation that is driven by corporate profits. This can happen through mechanisms like price gouging, price fixing or windfall gains resulting from information asymmetry, monopoly-like power and external shocks to the economy.
