IS-LM model

A model of aggregate demand that shows what determines aggregate income for a given price level by analyzing the interaction between the goods market and the money market

Labor unions

An organization formed by workers to strive for better wages and working conditions

Keynesian multiplier

Autonomous consumption or investment causes a more than proportional increase in income and employment. The total effect of the autonomous consumption on income. 1/(1-MPC)

German Great Depression

It led to a decline in the standard of living, a rise in political extremism, and the eventual rise of the Nazi Party.

The General Theory

Written by Keynes as a response to the great depression. This represents Keynes main work that the school of thought is based off of.

Phillips curve

a curve that shows the short-run trade-off between inflation and unemployment

Fiscal policy

attempts to manage the economy by controlling taxing and spending.

Monetary policy

attempts to manage the economy by controlling the money supply and thus interest rates.

2008 crisis effect on US

caused millions of Americans to lose their jobs and homes. The crisis also damaged the US economy and financial system, and it took several years for the US to recover.

Coordination problems

if number of parties is very large, coordinating them may be costly, difficult, or impossible

Explain the Keynesian Cross

income-expenditure equilibrium as the point where the planned aggregate spending line crosses the 45-degree line. Increasing government spending can have an exponential increase in GDP after that the government will make the money that was spent initially back in taxes "simplified version of Keynes General theory"

Podcast- Gold Standard RIP

introduction to the gold standard and its legacy. The value of a country's currency was pegged to the value of gold. This meant that the government would exchange gold for currency at a fixed rate.

Animal spirits

psychological factors that lead to changes in the mood of consumers or businesses, thereby affecting consumption, investment, and GDP

Solow Model

Traditional growth theory with focus on capital. Because 1. increase output per worker and 2. Wealthy have more capital goods and investment and growth are correlated.

Explain two advantages and two disadvantages of the Gold Standard according to the Wikipedia article?

Two advantages of the Gold standard were a. limited currency fluctuations because of the rigidity that was placed on currency because of the backing by gold b. there was a global exchange rate for currencies that could be used across the world and couldn't be manipulated. Two disadvantages of the gold standard were a. the governments ability to manipulate the money supply was limited so they couldn't help ease recessions (some say this caused the Great Depression but all agree the way it was handled had an impact on the depression) and b. countries with the ability to mine gold had a large advantage over countries that didn't have access to the production of gold.

Great Depression Origins

US 1929 large sell-off and bank runs

Great Recession

severe economic downturn that lasted from late 2007 through mid-2009

Great Depression causes

1)United State's stock market crash of 1929. 2)Big drop in the world's economy. 3)Overproduction of goods from World War I. 4)Decrease in the need for raw materials from non industrialized nations

Causes of the Great Recession

Banks and other financial institutions used leverage to amplify their profits, but this made them more vulnerable to losses. Deregulation of the financial industry allowed banks and other financial institutions to take on more risk. When the housing bubble burst, many borrowers defaulted on their subprime mortgages.

New-Classical

Believe in Real Business Cycle Theory; Argue that governments shouldn't try to fight business cycles; Emphasize the effect of external shocks and technology on aggregate demand

Gold Standard origins

British introduced the gold standard to their colonies making it spread across the world

Short-term fluctuations

Changes in business and economic activity that occur within the year.

money neutrality

Changes in money supply does not affect real variables like GDP. They only change prices.

Monetary sector

Contains money and financial instruments

Podcast- 'History Is A Battle Between Creditors And Debtors'

Creditors want to be repaid, and they want to earn interest on their loans. Debtors want to borrow money at the lowest possible interest rate, and they want to be able to repay their loans on their own terms. This conflict of interests can have a number of economic consequences, such as credit crunches, recessions, and financial instability.

Keynesian models

Economic models with slowly adjusting (sticky) prices which need government intervention to alleviate some of the problems caused by sticky prices

Keynes

English economist who advocated the use of government monetary and fiscal policy to maintain full employment without inflation (1883-1946)

Spare capacity

For a whole economy, this exists when long run aggregate supply is greater than aggregate demand and so there is a negative output gap.

Austrian economists

Free-market is best, Governments negative Mathematical models ignore consumer preference

GDP

Gross Domestic Product- the total market value of all final goods and services produced annually in an economy

Milton Friedman

He was a famous American economist. He strongly promoted the idea of free trade and condemned government regulation and socialism.

Turning point in Great Depression

Increase in Governement spending, world war 2, leaving gold standard.

Involuntary unemployment

Individuals who want a job can't find a job for the price they need or want

Explain the Keynesian unemployment diagram

Keynes says that wages are sticky and the classics say the are flexible... The top graph determines an equilibrium wage based on the supply and labor. the point on the top graph creates the Aggregate supply on the bottom graph which compares aggregate demand and supply to find the production as a function of labor.... Crisis sends the bottom graph from e0 to e1 which shift the demand to AD1. This is where the differentiation comes-> Classics believe that the prices and wages will go down proportionally meaning the real wage stays in equilibrium and same production. Keynes says that because of sticky wages-> when price goes down wages are rigid which creates an increase in real wages and the difference in Ls and Lp is unemployment. So, the government should step in to limit unemployment.Thus the critical point the rigidity or stickiness of wages in the economy.

Conclusion of Keynes paper

Keynesian economics has made a comeback in the UK and the USA. Mainstream economists now believe that a fiscal stimulus is an effective way to promote recovery during a severe recession. Randall Wray employs this argument to support Modern Monetary Theory (MMT) by showing how deficits can self-correct due to private-sector wealth and income effects

MV = PY

M = Money supply, V = velocity of money, P = price level, and Y = real production. If the velocity is constant, and given the Y depends on factors of production M and P are positively correlated. An increase in the money supply will lead to inflation

Unemployment

Measures the number of people who are able to work, but do not have a job during a period of time.

Paul Samuelson

One of the most prominent economists of the 20th century. Founder of the "neoclassical synthesis" combining classical and Keynesian ideas

Effective Demand

The desire for a good or service backed by an ability to pay

Explain the regulation in 2008

The financial industry was largely unregulated in the years leading up to the 2008 crisis, allowing banks and other financial institutions to take on excessive risk.

"Rules of the Game"

The way that countries went about implementing the gold standard

Demand side factors

These factors cause an increase in demand that exceeds the current level of goods and services

This Yale economist's formulation of Keynes' liquidity preference theory is similar to Milton Friedman's modern restatement of the quantity theory as a theory of money demand.

Imperfect competition

a market structure that does not meet the conditions of perfect competition

Stagflation

a period of slow economic growth and high unemployment (stagnation) while prices rise (inflation)

Paradigms

a set of shared assumptions, concepts, and methods that economists use to understand and analyze the economy.

Quantity theory of money

a theory asserting that the quantity of money available determines the price level and that the growth rate in the quantity of money available determines the inflation rate

Liquidity preferences

a theory that helps explain capital budgeting and, when applied to international operations, means that investors are willing to take less return in order to be able to shift the resources to alternative uses

classical models

economic models that assume wages and prices adjust freely to changes in demand and supply

Keynesianism on RBC

emphasis demand side fluctuations. He believed that agents were often irrational and that they made mistakes. He also believed that markets were not always efficient.

real business cycle school (RBC)

emphasizes the role of real shocks, such as technological change and productivity shocks, in driving economic fluctuations.

Market Rigidities

factors that prevent markets from functioning perfectly. They can make it difficult or impossible for prices to adjust to changes in supply and demand.

Stabilization policies

government policies that are used to affect planned aggregate expenditure, with the objective of eliminating output gaps

Endogenous-growth

growth driven by factors inside the economy

Smoot-Hawley Tariff Act

legislation passed in 1930 that established very high tariffs on foreign goods. Its objective was to reduce imports and stimulate the domestic economy, but it resulted only in retaliatory tariffs by other nations that made the Great Depression worse

example of mps and mic

me. This means that if incomeincreases by US$ 1 and consumption increases by US$ .80, this means that MPC =0.8 and MPS (marginal propensity to save) = 0.2.

flexible prices

product prices that freely move upward or downward when product demand or supply changes (classical)

Money illusion

occurs when people interpret nominal changes in wages or prices as real changes

Dissaving

occurs when people withdraw funds from their previously accumulated savings

Technology shock

positive, sudden or unexpected increase in a supply

Explain the graph of classical model

start in quad 2 (top right) where a demand shock moves AD0 to AD1 which increases prices from P0 to P1. This increases Wages from W0/P) to W0/P1 which creates a higher demand from labor than the supply of labor in the bottom left. Classical say this moves immediately back to equilibrium but Keynes would say that because of price rigidities the government is needed to step in to increase wages and reduce demand

Modern macroeconomics

studies the behavior of the economy as a whole. It examines topics such as economic growth, inflation, unemployment, and business cycles.

Say's law

supply creates its own demand. This means that the production of goods and services creates the income that people need to purchase those goods and services.

Time inconsistency

tendency to systematically misjudge at the present time what you will want to do at some future time

Rules rather than discretion

the idea that economic policymakers should follow pre-set rules, rather than making decisions on a case-by-case basis.

Neoclassical synthesis

the idea that markets can be slow to adjust in the short run due to sticky prices and sticky wages but revert to long-run classical principles which could be aided by appropriate use of fiscal and monetary policies

the process by which poorer countries tend to grow faster than richer countries (diminishing returns)

Precautionary and speculative motives

the response to uncertainty in the market

Wynne Godley- Paper

the stock-flow argument that showcases Wynne Godley's perspective on government debt. They use a closed economy model where output depends solely on aggregate demand and government finances its budget deficit by issuing bonds to the private sector.

Labor markets

the supply pool from which employers attract employees

Rational expectations

the theory that people optimally use all the information they have, including information about government policies, when forecasting the future
