Phillips Curve Notes

The Phillips Curve and Its Modern Uses


William Phillips: 1958
Paul Samuelson and Robert Solow: 1960
Edmund Phelps:  2006 Nobel Prize

The Original Short Run Phillips Curve

Basic Assumptions:

·        There is an inverse relationship between inflation and unemployment.  When one increases, the other decreases.

·        If an economy has inflation, usually due to demand pull growth, then more workers are being hired to produce the greater number of goods being produced.

·        If an economy is in a recession, more resources are being left idle, therefore fewer workers are needed and less pressure is put on the resource base.  This results in less inflation.

·        Movement along the Phillips Curve represents year to year changes in the business cycle.

The original data collected in the 1940’s and 1950’s showed this general connection with the business cycle. This also held during the 1960’s in the US (see most texts).  


Why the Phillips Curve?  
Original SR Phillips Curve

Inflation and Unemployment =
There is an assumed inverse relationship
Inflation =

Increases as the economy expands
Recession =

Unemployment increases as the economy slow down, contracts
Along the Curve =

Cyclical changes in the GDP
Stagflation

Late 1970’s to 1981

Increasing inflation and unemployment during the same year
Data?

1974, 1980, 1981….
A New Phillips Approach

New Range?

The SRPC can move outward and inward as well as illustrate the business cycle
Cost Push Inflation

More stress on resources, wages, input costs
Supply Shocks

Rapid loss of resources or rapid increase in resource costs
SRPC Curve moves

Outward during these Shocks
SRPC moves back

Inward as the society increases productivity or regains resources
Long Run Phillips Curve

Inflation?

Society adjusts for cost/wage increases with new prices.  “Real” balances
LRPC is?

The efficient Production Possibilities Frontier
Natural Rate of Unemployment
Becomes the equivalent of the Full Employment Unemployment Rate
Phillips and AD/AS Curves

Change points on SRPC =

If AD changes, move points on the SRPC
Move the SRPC =

If SRAS changes, move the SRPC


The Problem of Stagflation

Phillips Curves under attack:

·        Starting in the mid-1970’s the economy started to suffer from increasing amounts of inflation and unemployment (see the Business Cycles Data chart).

·        The data points on the Phillips Curve no longer fit into any immediately recognizable pattern.

·        Did the model seem to present the relationship between inflation and unemployment too simplistically?


A New “Phillips” Approach

Stagflation, and its removal, explained:

·        If the fundamental efficiencies and demographics of an economy change, then the relationship between inflation and unemployment is still valid, just in a new range.

·        One key change is the type of inflation.  If inflation now becomes “cost push” inflation, the resource base has now changed.  The aggregate supply is reduced due to resources being used up or lost, disasters, boycotts, etc.  More costs and job losses occur.

·        The result of cost push inflation will be higher prices due to fewer and more expensive resources, plus more unemployment due to business production cuts.  This is also known as a supply shock.

·        The Short Run Phillips Curve still has a relationship between the two factors, but the curve moves outward.  Year to year business cycles still occur, just at higher levels than before.

·        When the economy is able to adjust with improved technologies, or the resource supply is re-established, the inflation pressures level off and businesses are able to lower costs and produce more.  The SRPC moves back inward (to the left). 

·        This approach appears to answer the late 1970’s changes.  As energy resources were cut and significant demographic changes like women moving into the workforce changed, the economy suffered from stagflation.  This was “cured” by the restoration of cheaper energy and new technologies in the 1980’s and 1990’s.

·        The logic of the Phillips Curve was intact, just in new ranges.



The Long Run Phillips Curve

Inflation has less importance in the Long Run.

·        Two new factors emerge in Long Run analysis.  The first is that the economy can adjust for inflation in the long run through wage and real-wage changes.  The second is based on Rational Expectations School theories that expected inflation rates are controllable and predictable by the market, therefore no longer a random factor. 

·        The Long Run Phillips Curve is therefore vertical at some natural rate of unemployment. This is now presumed to be around 4 to 5 % for the US and 6% for Canada.  This vertical LRPC is also known as the NAIRU line, or “non accelerating inflation rate of unemployment”. 


·        The analysis of the LRPC is now based on arguments of how a country can change the natural rate of unemployment.  Usually this is connected to long run productivity of the workforce and the willingness of a country to help those who are unemployed.   The theory is that financial assistance given to those who lose jobs will lengthen their “willingness” to wait, or settle, for new jobs.   This will increase the natural rate of unemployment (move it to greater levels of unemployment). 


The Phillips Curve and the AD/AS Model

Phillips Curves and AD/AS Graphs:  Mirror Images

·        When you move points along the SRPC you are showing changes in the year to year business cycle.  This is exactly what you are illustrating when you move the AD line on the AD/AS model.

·        When you move the entire SRPC outward to show supply shocks or cost push inflation problems, it is exactly the same at moving the SRAS curve inward. The AD/AS model will also show the simultaneous creation of greater inflation and more unemployment. This will also be true of movements in the opposite directions, like the SRPC moving back inward is the same as the SRAS curve moving outward to better levels of inflation and production.



Current Thinking About the Phillips Curve

Recent and growing critiques of the Phillips Curve use:

·        I quote a brief article from Dr. D. Hamermesh of the University of Texas at Austin, “By the mid-1980’s the Phillips Curve was no longer taught as offering a trade-off between inflation and unemployment and was hardly mentioned in economics courses anymore.”  “…Nobel Prize winners Milton Friedman and Edmund Phelps suggested that there was no good theoretical basis for the relationship…”  These words are typical of university critiques of the curve.
  • Data from the 1990’s forward also seems to show that economies like the US can sustain long periods of growth, with falling inflation and low, steady levels of unemployment.
