    MISOC Workshop September 15th 2014

  • Motivation •  Many  of  the  key  determinants  in  the  trends  in  income  inequality  and  in  

    overall  living  standards  over  the  past  25  years,  including  since  the  financial  crisis,  have  been  driven  by  changes  in  the  labour  market,  including,  for  the  UK:  –  huge  increase  in  entry  cohorts  with  at  least  a  BA  degree  during  the  1990s  

    and  early  2000s,  –  large  relaHve  rise  in  top  ‘earnings’  percenHle  since  the  early  1990s,  –  dramaHc  fall  in  real  wages  since  2008,  ….  

    •  To  which  we  can  add  changes  in  savings  and  asset  prices,  in  parHcular  housing;  and  reforms  to  taxes  and  welfare  benefits.  

    •  Aim:  To  layout  a  framework  for  examining  the  role  of  interacHons  between  labour  market  shocks,  asset  markets  shocks  and  changes  to  the  tax  and  welfare  system,  in  the  evoluHon  of  inequality,  –  allowing  an  interpretaHon  of  what  has  happened  in  the  UK,  and  also  in  the  US  and  elsewhere.    

  • Inequality over the Working Life •  Begin  by  focussing  on  the  labour  market  as  a  primary  source  of  shocks  

    and  examine  the  links  between  the  various  definiHons  of  economic  inequality:    

    •  wages  =>  earnings  =>  joint  earnings  =>  income  =>  consumpHon  –  the  link  between  the  various  measures  of  inequality  is  mediated  by  

    mulHple  `insurance'  mechanisms  including:  

    1.  (Family)  labour  supply  (wages  →  earnings  →  joint  earnings)  2.  Taxes  and  welfare  benefits:  (earnings  →  income)  3.  Assets:  Saving  and  borrowing  (income  →  consumpHon)  4.  Informal  contracts,  gi^s,  etc.  •  But  how  important  are  each  of  these  mechanisms?  •  How  do  they  change  over  the  life-‐cycle  and  the  business  cycle?  •  How  should  we  design  policies  to  best  insure  these  shocks?  First  look  at  income  and  consumpHon  inequality  by  year  and  by  cohort….

    ConsumpHon  Inequality  by  Year  and  Birth  Cohort  -‐  US  

  • Inequality dynamics •  Similar  episodes  of  growth  in  income  inequality  can  have  very  

    different  dynamic  underpinnings,  with  different  policy  implicaHons.    •  Studying  the  the  relaHonship  between  inequality  in  income,  

    consumpHon,  wages  and  earnings  can  bring  some  structure  to  the  key  features  of  inequality.    

    •  A  ‘shock’  to  the  earnings  of  one  family  member  may:    –  generate  reacHons  in  the  labour  supply  of  other  family  members,    –  be  compensated,  in  part,  through  the  welfare  benefit  system,  –  perhaps  also  through  drawing  on  savings  and  net  equity,    –  and  even  through  informal  networks.    

    •  This  is  the  moHvaHng  idea  for  the  Blundell,  Pistaferri  and  Suporta  (2013)  study,  which  uses  data  from  the  new  PSID,  1996  –  2010,  –  new  panel  data  measures  of  consumpHon,  earnings  and  assets;  –  and  previous  studies  using  mixtures  of  panel  and  c-‐s  data.    

  • Consumption inequality dynamics •  BP  (QJE  1998)  and  BPP(AER  2008)  approach  relates  transitory  and  persistent  

    log  income  shocks  to  log  consumpHon.  In  a  simplified  form:  

    Δ lnYit ≈ ν it +Δξitpermanent income shocks

    transitory income shocks

    Impact of shocks to asset prices, etc.

    Ratio of net assets to net assets plus human capital wealth – insurance value of net assets

    Δ lnCit ≈ Γit +φ(1−π it−1)ν it +ψγ tL (1−π it−1)ξit +εit

    •  Relates  the  evoluHon  of  the  income  distribuHon  to  consumpHon  distribuHon  –  Persistent  shocks  will,  in  general,  have  a  larger  impact  on  consumpHon;  –  ϕ  and  ψ  allow  for  excess  smoothness  and  excess  sensiHvity;  and  for  net  savings  to  be  

    used  to  ‘insure’  shocks.  

    •  Income  inequality  episodes  differ  in  underlying  persistence/durability  –  Using  variance  of  log  for  UK  and  US  find  strong  growth  in  variance  of  persistent  shocks  

    in  early/mid  1980s  for  all  cohorts  and  early/mid  1990s  for  certain  key  working  age  cohorts.

  • Implied variance of permanent shocks by cohort – Britain The ‘spike’ in persistent shocks - very similar in US, BPP (AER, 2008)

    Source: Blundell and Preston (1998)

  • Consumption inequality dynamics with family earnings •  Blundell,  Pistaferri  and  Suporta  (2013)  generalise  this  framework  to  allow  

    for  mulHple  earnings  in  a  family  –  Wage/earnings  shocks  can  be  correlated  across  family  members  –  Labour  supply  can  respond  across  family  members    –  Taxes  and  welfare  benefits  deliver  net  current  period  income  –  Labour  supplies  and  consumpHon  can  be  non-‐separable  

    •  Some  findings:    –  a  key  role  for  family  labour  supply  in  providing  insurance  for  adverse  shocks,  

    especially  for  those  with  low/no  net  assets,    

    –  substanHal  role  for  taxes  and  welfare  benefits,  and      –  once  family  labour  supply,  taxes,  welfare  benefits  and  savings  are  taken  account,  

    there  is  lirle  role  for  any  other  insurance  mechanisms.    

    •  Recent  recession  –  assets  and  real  wages  suffer  an  adverse  shock:  –  consumpHon  falls  for  non-‐durables/necessiHes,  largely  across  the  distribuHon,  

    implying  strong  persistent/uninsurable  shocks;  

    –  labour  supply  of  women  and  older  workers  is  maintained,  even  enhanced;  –  ‘double  whammy’  implies  strong  role  for  welfare  benefits  and  tax  credits.  

  • For the rest of the talk….

     Focus  mostly  on  the  UK:  

    1.  Earnings:  Wage  Changes,  Employment  (and  ProducHvity)  2.  Incomes:  Working-‐age  (and  Pensioners)  3.  ConsumpHon:  Durable  and  Non-‐durable  Expenditures  –  think  about  what  they  tell  us  about  the  process  of  inequality  and  living  

    standards  since  the  recession  in  the  context  of  the  ‘insurance’  model,  

    –  briefly  examine  the  prospects  for  the  future.    -‐  the  key  idea  is  to  use  the  link  between  earnings,  incomes  and    consumpHon  to  build  a  more  detailed  picture  of  the  process  and    prospects  for  inequality.

    Source: Blundell, Green and Jin (2014) Notes: the discontinuities in occupation classification in 2001 and 2011 have been addressed in the following way. For the conversion of SOC 1990 to SOC 2000, we look at individuals who were surveyed in 2000Q4 and 2001Q2 and stayed with the same employer and infer the transition matrix from this group. For the conversion of SOC2010 to SOC 2000, we used the ONS two-way tabulation of the LFS 2007 Q1 sample by the major occupation groups under the two SOC systems.

  • Implications for Inequality •  Persistent  changes  

    –  evidence  from  distribuHon  of  consumpHon,  and  labour  supply  responses,  implies  strong  persistent/uninsurable  shocks  for  certain  key  birth  cohorts.  

    •  Longer  term  earnings  growth  will  mostly  come  from  high-‐skilled  occupaHons,    –  enhancing  the  top  deciles  of  the  income  distribuHon.    

    •  Lirle  progression  and  low  producHvity  for  the  low  skilled  part  of  the  distribuHon  –  incomes  at  the  borom  will  only  be  maintained  through  family  labour  supply  and  the  

    benefit/tax-‐credit  system  (and  younger  adults  staying  at  home).    

    •  Studying  the  the  relaHonship  between  inequality  in  income,  consumpHon,  wages  and  earnings  brings  structure  to  the  key  features  of  inequality  and  living  standards    –  consumpHon  falls  much  more  than  in  past  recessions,  even  for  necessiHes,  –  labour  supply  of  women  and  older  workers  is  maintained,  even  enhanced,  –  for  low  skilled  with  few  assets,  family  labour  supply,  family  structure  and  welfare  are  

    key  insurance  mechanisms.  

    •  Providing  a  picture  of  the  dynamics  of  inequality  and  living  standards  over  the  austerity  period  and  a  sense  of  the  likely  evoluHon  in  coming  years.  

    •  SHll  need  to  do  more  on  this  with  Understanding  Society…..

  • What have we learned? •  Changes  in  the  labour  market  are  a  key  factor  behind  the  changes  in  overall  

    living  standards  and  inequality  –  especially  for  younger  families/singles    

    •  Real  wages  and  employment  tell  much  of  the  story  –  real  wages  have  fallen  across  the  distribuHon,  –  large  increases  in  entry  cohorts  with  BA  have  maintained  their  BA  premium,  even  in  the  

    recession  but  they  have  also  suffered  the  overall  decline  in  real  wages,  

    –  the  poor  employment  and  earnings  performance  of  young  low  educated.  

    •  Benefit  changes  are  also  important  drivers  –  key  impact  in  the  near  future  too  …  

    ©  InsHtute  for  Fiscal  Studies      

  • Prospects - summary •  Younger  workers  and  families  are  acHng  as  if  they  expect  a  long-‐run  fall  

    in  relaHve  living  standards,  quite  far  up  the  distribuHon.  –  evidence  from  consumpHon,  savings  and  labour  supply.  

    •  Real  wages  (and  producHvity)  have  been  slow  to  pick  up  –  expect  the  parern  of  lower  real  wages  to  conHnue,  but  with  fairly  buoyant  

    employment  due  to  increased  supply.    

    •  Most  falls  in  real  earnings  have  happened  (but  low/no  real  growth)    –  fiscal  contracHon  implies  large  benefit  cuts  in  near  future.  

    •  The  number  of  rouHne  jobs  near  the  middle  of  the  earnings  distribuHon  has  declined  steadily  –  more  jobs  are  now  professional  or  managerial,  ‘successful’  absorpHon  of  the  higher  

    numbers  with  degrees.    

    •  Suggests  longer  term  earnings  growth  will  mostly  come  from  high-‐skilled  occupaHons,  enhancing  the  top  of  the  income  distribuHon.    

    •  Lirle  evidence  of  earnings  progression  for  lower  skilled.    

  • Prospects - II •  But  sHll  much  to  do  in  focussing  on  older  workers  in  general,  on  return  

    to  work  for  parents/mothers,  and  on  entry  into  work.  

    •  There  are  sHll  some  potenHal  big  gains  here,  –  for  example,  as  (higher  skilled)  women  age  in  the  workforce.  

    •  Tax/welfare  reforms  to  enhance  earnings  (from  Mirrlees):    –  refocus  incenHves  towards  transiHon  to  work,  return  to  work  for  lower  

    skilled  mothers  and  on  enhancing  incenHves  among  older  workers.    

    •  ProducHvity  is  sHll  the  key,  –  (financial)  capital  misallocaHon  and  potenHal  investment  returns.  

    •  Human  capital  and  ‘on  the  job’  wage/producHvity  complementarity  –  note  the  relaHve  importance  of  mismatch  of  entry  skills  in  the  recession.  

    •  ProducHvity  and  wages  are  closely  related  but  note  recent  growth  in  the  wedge  between  labour  costs  and  hourly  wages,  –  the  growing  importance  of  pensions  and  NI  in  the  UK,  –  what  will  the  trends  in  this  wedge  look  like?

    Source: Blundell, Green and Jin (2014)

  • Can  changes  in  the  composiHon  of  the  workforce  explain  the  fall  in  real  hourly  wages?  

    •  Short  answer:  no  –  unlike,  to  an  extent,  in  other  countries.  

    •  As  in  previous  recessions,  the  composiHon  of  the  workforce  shi^ed  towards  more  producHve  workers,    –  hence  we  would  have  expected  the  average  real  wage  to  increase  

    (other  things  being  equal).  

    •  What  has  been  different  in  this  recession  is  that  the  returns  to  those  characterisHcs  have  fallen  substanHally.  

    •  This  is  true  even  amongst  workers  who  keep  their  jobs,  who  have  experienced  nominal  wage  freezes/real  wage  falls,  –  May  have  been  facilitated  by  the  reduced  power  of  labour  market
