## The neoclassical phillips curve tradeoff

The Keynesian Perspective introduced the Phillips curve    and explained how it is derived from the aggregate supply curve. The short run upward sloping aggregate supply curve implies a downward sloping Phillips curve; thus, there is a tradeoff between inflation and unemployment in the short run. By contrast, a neoclassical long-run aggregate supply curve will imply a vertical shape for the Phillips curve, indicating no long run tradeoff between inflation and unemployment. [link] (a) shows the vertical AS curve, with three different levels of aggregate demand, resulting in three different equilibria, at three different price levels. At every point along that vertical AS curve, potential GDP and the rate of unemployment remains the same. Assume that for this economy, the natural rate of unemployment is 5%. As a result, the long-run Phillips curve relationship, shown in [link] (b), is a vertical line, rising up from 5% unemployment, at any level of inflation. Read the following Work It Out feature for additional information on how to interpret inflation and unemployment rates.

## Tracking inflation and unemployment rates

Suppose that you have collected data for years on the rates of inflation and unemployment and recorded them in a table, such as [link] . How do you interpret that information?

Year Inflation Rate Unemployment Rate
1970 2% 4%
1975 3% 3%
1980 2% 4%
1985 1% 6%
1990 1% 4%
1995 4% 2%
2000 5% 4%

Step 1. Plot the data points in a graph with inflation rate on the vertical axis and unemployment rate on the horizontal axis. Your graph will appear similar to [link] .

Step 2. What patterns do you see in the data? You should notice that there are years when unemployment falls but inflation rises, and other years where unemployment rises and inflation falls.

Step 3. Can you determine the natural rate of unemployment from the data or from the graph? As you analyze the graph, it appears that the natural rate of unemployment lies at 4%; this is the rate that the economy appears to adjust back to after an apparent change in the economy. For example, in 1975 the economy appeared to have an increase in aggregate demand; the unemployment rate fell to 3% but inflation increased from 2% to 3%. By 1980, the economy had adjusted back to 4% unemployment and the inflation rate had returned to 2%. In 1985, the economy looks to have suffered a recession as unemployment rose to 6% and inflation fell to 1%. This would be consistent with a decrease in aggregate demand. By 1990, the economy recovered back to 4% unemployment, but at a lower inflation rate of 1%. In 1995 the economy again rebounded and unemployment fell to 2%, but inflation increased to 4%, which is consistent with a large increase in aggregate demand. The economy adjusted back to 4% unemployment but at a higher rate of inflation of 5%. Then in 2000, both unemployment and inflation increased to 5% and 4%, respectively.

Step 4. Do you see the Phillips curve(s) in the data? If we trace the downward sloping trend of data points, we could see a short-run Phillips curve that exhibits the inverse tradeoff between higher unemployment and lower inflation rates. If we trace the vertical line of data points, we could see a long-run Phillips curve at the 4% natural rate of unemployment.

this means that the demand curve have negative relationship with the price ..which means that when high price low demand of the product and vice versa so higher price will shirnk the demand of product

What are the various reasons for the Federal Reserve to increase the fed rates?
What is unemployment
Unemployment is a term used to describe people who do not hold a paying job
JASON
what are the causes of unemployment
evans
unemployment refer to the situation in which people searching job but they have no. it also refers in which marginal productivity in zero.
Ramu
Causes of unemployment are: 1: Over Population 2: Break down of the family system 3: Rural/Urban Migration
Umar
unemployment simply means, in the situation where by people are looking for a job and their could achieve it.
Faruk
suppose you're the economist of ethiopia; when the country is face high rate of inflation what you recommend as one economist?
if consumer spend all their incomes on consumption what does it mean?
Roba
if the government spends more of its revenue on development infrastructure from the budget it have and lower tax collection the budget deficit will run why?
Roba
because tax is less than revenue
Bhat
what is demand
Demand is the quantity of goods and services that consumers are willing and able to purchase at various prices over a given period of time
the total value of goods and services produced by a coutry in it's own territorial area( mainly in a year) is called GDP
GDP- the total value of goods produced and services provided in a country during one year.

What is the formula for propensity to save
Zubair
there is no formula for propensity to save but it has a two types one is average propensity to save and marginal propensity to save where Apc is equal to saving divide by income and mpc is equal to change in saving due change in income
Bhat
yes ooo

what is inflation
Inflation is simply a situation in an economy where there is a persistent rise or increase in the prices of goods and services in a particular year(say current year)
JERRY
It can still be defined as a situation in an economy where there's a persistent fall in the value of money
JERRY
it is the persistent rise in the general price of goods and services in an economy leading to the fall in the values of money
Muafue
It could mean the central bank has a deficit in reserve unable to cope with low export and exit of foreign investments.
Wong
inflation is the general increase in a commodity with in a country.
Jimmy
Mr Fallah please take the definition again that one is not clear
Muafue
the persistence in general price of commodities
ezechy
The persistence rise in the general price level
Muafue
The persistence rise in general price of commodities

what is willingness
Is a person Able,Capable and Anxious to something
Muafue
Is when a person is able,capable and Anxious to do something
Muafue
thanks sir g.
Bilal
u are welcome
Muafue
where you from
Bilal
Cameroon
Muafue
And you
Muafue
Pakistan
Bilal
How far are you in Education
Muafue
who about my question What is MPC
sabawoon
is marginal propensity to consume
Muafue
a little more
sabawoon
sorry muafue sir you are little bit wrong about willingness *willingness reffers how much wants . it could be wants for payment or wants for something to do.
MPC reffers *How much want to consume*.
MPC is Marginal Propensity to Consume. MPC is proportion of additional spent on consumption.
Bon
MPC is Marginal Propensity to Consume. MPC is the proportion of additional income spent on consumption.

What is difference between GNP and GDP?
Zahid
GNP is gross national product. In calculating GNP we include net national income from abroad while GDP is gross domestic product and in calculating it we use on expenditure, income and output from within the country. My name is JERRY NGONDA from Cameron
JERRY
GNP.the total value of good \$service currently produce w a given period of time by domestic owner GNP=NFI+GDP:GDP is a market value of final good \$service currently produce in a given period of time w in a country boundery or territors.its take produce currently \$etc
yes.no suggestions
when spending by the federal government exceeds net taxes?
explain the difference between macroeconomics and microeconomics
Rahmo
Macroeconomics is the study of economics at the aggregate level while Micro is at the individual level.
