low unemployment


Introduction
Jobless
Jobs created in the economy
What is unemployment and how is it measured
People of the working agge who are without work. available for work and activly seeking owrk
Labor force- economiucaly active population
Different ways to measure- exp(people claiming benefits.
Hidden unemployment
People given up on looking
Part time jobs, who dont want part time
Working a job they are greatly over qualified for
Distribution of unemployment
Inequalities inside the economy, disparities
- geographical disparities: some parts of the country are more prosperous
- age disparities: unemployment rates in the under- 25 age group are hiugher thn the national average
- ethnic differences: Ethinic minorities ofton suffer from higher unemployment, (may be from prejudice)
- gender disparities: unemplyment among woman hhas been higher due to prejudice
Costs of unemployment
Important because of the high costs
- costs to the unemployed: receive less income, lower standard of living, dejected, stress and erosion of mental health
- areas of unemployyment there are poverty, homlessness, higher rates of crime and gang activity
Connectted not solely
-Costs of unemployment to the economy as a whole: less output, government spening
what are the main factos affecting the level of unemployment
Inflows and out flows dor unemplyment
Inflows- people beoming unemployed
·         peopl;e who have lost their jobs
·         people who have resigned
·         people who hav left school and not found work
·         people who are trying to return to work after having left it
·         people who have immigrated into the country but have not yet found work

outflows- no longer unemployed

·         people who find jobs
·         people who retire
·         people who go back into education
·         people who choose to stay at home
·         people who emigrate
·         people who give up search for jobs
·         people who die

Causes of unemployment
- the labour market

Real wage W/P will be equal to the equilibrium real wage in the classical model
 

Without government intervention and trade unions, the labor market will always be in equilibrium in the classical model. This means that the real wage will be equal to the equilibrium real wage - the level of real wage which will equilibrate the labor demand and the labor supply.
 

http://www.expertsmind.com/macroeconomics-assignment-help/images/equilibrium-in-labor-market.PNG
Shows demand and supply for all labour


It is also clear from the graph that the total amount of labor L is determined in the labor market. When the real wage is equal to the equilibrium real wage, the supply of labor is equal to the demand for labor and this is the amount that will be used in the production.


If real wages are higher than the equilibrium real wage, the demand for labor will be less than the supply. The difference is the amount of unemployment beyond the natural rate of unemployment. In equilibrium, there is therefore no "involuntary" unemployment in the classical model.

Disequilibrium unemployment












Real wage unemmplyment
Trade unions and government are interferein g with the market thus the wages are set abnove equilbrium, preventing market from clearing

Solution to real wage unemployment
Reduce trade unions ability to negotiate higher wages
Lower minimum wage
Effect poor workers, greater inequity
Demand deficent- unemployment or cyvlical unemployment

http://www.colorado.edu/Economics/courses/econ2020/section6/gifs/fig61.gif

Solution to demand defecient unemployment
Due to a low level of eggregate demand. use keynesian demand managment policies
Lower taxes. decrease interest rates, increasing market supply

Equilibirum unemployment
People are unwilling or unable to take the jobs that are available
Lack education, or unwilling
Gap becomes smaller as higher wages are offered
·         frictional
·         seasonal
·         structural
Frictional unemployment
In between jobs, left education waiting.
Not considered bad
-solutions: lower unemployment benefits
Improbving flow of information
Seasonal unemployment
Unemployed on a seasonal basis
Tourisms works in seasons
Fix:take different jobs during off season- information
Structural unemployment
Worst type
Structural unemployment is a form of unemployment resulting from a mismatch between demand in the labour market and the skills and locations of the workers seeking employment. Even though the number of vacancies may be equal to, or greater than, the number of the unemployed, the unemployed workers may lack the skills needed for the jobs, or they may not live in the part of the country or world where the jobs are available.
·         autaumation-reduces need for labour
·         lower cost of labour in foreing contries
·         changes in consumer taste (coal)
Solutions
·         A change in the education system-
·         adult retraining programs
·         give subsidies to firms to higher more people
·         ecourage people to move to an area
·         apprenticeship programs
Solutions to structural unemplyment/ marketbased
·         reduce unemployment benfits
·         deregualtion of labor market
burden- people lose their benefits and now have even worse standards of living
worst conditions for labour
inequity


Are demand sife policies or supply side policies more effective in reducing unemployment
Both good
Crowding out
Problem with running a deficient
Lowers incentive for businesses to invest
Gov got opposite of what they wanted

Aggregate supply


Aggregate supply
Aggregate supply
Aggregate supply is the total amount of goods and services produced by an economy in a year
Short run
http://tutor2u.net/economics/content/diagrams/aggsupp1.gif
Short run is when all the factors of production do not change

do not change so there is a positive relationship between output and average price levels.
Shifts in sras
https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjExgZpvcWadcCKsMNBuCKINf3Zg5nAS6uaEBW5E3OKbnfVb6okn0SQ-v46vZ73dVub3FcquBR9rOJXICOdoPvPqWXuFcSyZzeq1R73NCMQ-zUVTm82nq4XolrPB3Oet-oZObniknTAjS8/s1600/shifts+in+SRAS.png
A change in anything other than price level will result in a shift in the SRAS curve

Supply side shocks
Typical changes-

A change in the wage rates

A change in raw materials

A change in the price of imports

A change in government indirect taxes and subsidies

Combining AD and AS in the short run
The economy will meet at the equalibrium
Long run aggregate supply
New classical LRAS
Beleif in the effeciency of the market/ little gov. intervention
   LRAS is vertical at Full employment level of output which represents potential output

LRAS is based on quality and quantity independent of price level.
http://www.amosweb.com/images/AgSp05.gif
Keynesian AS
http://www.bized.co.uk/sites/bized/files/images/keynrefl.gif
Phase 1: perfectly elastic phase- low output levels mean industries can increase output without incurring higher average costs due to spare capacity in the economy
Phase 2: security phase- as the economy approaches Yf spare capacity is used up and FOP are scarce. Producers start competing for scarce FOP so increased output means higher costs so higher average price levels
Phase 3: Economy has reached full capacity (yf) so output cannot be increased so competition amng firms for FOP results in increase average price levels (inflation) output cannot go up without a shift in the curve

Shifts in LRAS
Steady increase, move to the right if therwe is an improvement in quality of the factors of production, or increase.
Factor of production
Increase In quantity
Increase in quality
Land (all natural resources)
Land reclamation (Netherlands reclaiming the sea from the north sea)
Increase access to supply
Discovery of new resources
Tech advances that allow increased access or discovery of new resources
Fertilizers
irrigation
Labor + entrepreneurship
Increase of birth rate
Immigration
Decrease in natural rate of unemployment
Education
Training
Re-training
Apprenticeship programs
capital
Investment
Tech advances that contribute to more efficient capital
Resource and development
Supply side policies
Policies to increase supply
Market based and interventionist
Interventionist supply side policies (keynsisian)
Market based supply side policies (classic)
Investment in human capital
(education) (training)
Reduction in household income taxes
Research and development
Tax incentives, enforcing intellectual. Property rights or research and development in universities
Reduction in corporate taxes
Provision and maintenance of infrastructure
Labor market reform
1)reduce trade union power
2) reduce or eliminate minimum wage
3) reduce unemployment benefits
Direct support for businesses/industrial policies
Anti trust laws, helping small/medium sized firms become established and grow
Deregulation
Infrastructure- large scale capital which is necessary for economic activity to take place, usually provided by government
Privatizing
Policies to increase competition

Aggregate supply worksheet


Aggregate supply worksheet
Objective 1 and 2: define short-run aggregate supply (sras)
AS is the total amount of goods and services that all industries in the economy will produce at every given price level
Always long and short run
Short run is when all the factors of production do not change
The short run in microeconomics is the period of time when the prices of the factors of the production do not change so there is a positive relationship between output and average price levels.
Shifts in the SRAS curve
A change in anything other that price level will result in a shift of the whole sras curve
Typical examples of supply side shock
A change in wage rates
Ec. Gov increases min wage
A change in cost of raw material
-          Like oil
Define supply side shock- factors that result in changes (usually in increase) in the cost of production.
Decrease costs will cause sras to increase shift right
Increase in costs will cause sras to decrease- shift let
Typical examples of suuplu side shocks.
Changes in wage rates
Increase in wages- increase in cost of production to firms so a decrase in SRAS. IE.  Gov raises legal minimum wgae
Change in costs of raw materials
To affect SRAS the raw material must be significant. IE. Oil
So an increase in price of oil decrease in SRAS
Change in price of imports
Increase import prices decrease in SRAS
A fall in currency value -> more expensive imports decrease in SRAS
Changes in gov indirect taces or subsidies
Increase in taxes-> incease cost to firm -> decrease in SRAS
Decrease in subsidies -> increase cost to firm-> decrease in SRAS

Equilibrium
Short run macroeconomic equilibrium occurs when aggregate demand is equal to SRAS
The long run is a time period long enough that all factor prices change
LRAS is highly dbated among economists
The two types of LRAS are:
The Keynesian LRAS curve
The neo-classical LR         AS curve
-The keynesisian LRAS curve
-          Three phases.
Objective 4: distinguish between the short run aggregate supply curve (sras) and the long run aggregate supply curve (Lras)
Short-run aggregate cupply (sras)- shows a positive relationship between level of putput and average price levels because prices of factors of production are fixed
Long-run aggregate supply curve LRAS- Represents the level of output at full employment *natural rate of unemployment) or when the economy reaches its potential output
Keynesian AS
The Keynesian AS curve shows three phases and does not really distinguish between the SR and the LR
Phase 1: perfectly elastic phase- low output levels mean industries can increase output without incurring higher average costs due to spare capacity in the economy
Phase 2: security phase- as the economy approaches Yf spare capacity is used up and FOP are scarce. Producers start competing for scarce FOP so increased output means higher costs so higher average price levels
Phase 3: Economy has reached full capacity (yf) so output cannot be increased so competition amng firms for FOP results in increase average price levels (inflation) output cannot go up without a shift in the curve
Neo-classic monetarist (the Austrian school)
-          These schools of thought believe in the efficiency of the market so promote minimal gov intervention in the allocation of resources
-          LRAS is vertical at Full employment level of output which represents potential output
-          View asserts that the potential output is based entirely on the quantity and quality (productivity) of fop and not an price level
-          So LRAS is independent of price level, Price levels might raise but level of output does not change.


The LRAS curve will shift outward if there is an improvement in the quality (increase in productivity (output per unit of input) of fop) or an increase in the quantity of the factors of production
                -Improvement in quality and increase in quantity are both often due to advances in technology- so tech improvements are vital to supply side of any economy.
