Lecture 5: More on Labor Supply
2
Part 1: CPS Data
3
Wage, Income and Hours Data: Current Population Survey (CPS) Continue our theme of introducing you to major U.S. data. Current Population Survey: High quality data extends back to the 1960s. Large samples of U.S. households. Panel Dimension (4 months in, 8 months out, 4 months in). Detailed information about labor market status (every month). Detailed information about hours asked every month. Detailed information about hours/earnings – asked less frequently. Large sample sizes allow for analysis by U.S. states.

Part 2: Trends in The Natural Rate of Unemployment
5
Trends in The Natural Rate In Unemployment Did labor market conditions improve during the 1980s and 1990s? -Unemployment rates fell substantially Related concept: Do income or substitution effects dominate with respect to labor supply decisions? Must reads: Juhn, Murphy, and Topel “

7
Real Wages Over Time
8
Trends in Unemployment and Nonemployment
9
Breakdown of the Nonemployed
10
Breakdown of the Non-Participators: Rising Disability
11
Rising Disability Among the Persistently Unemployed
12
Autor and Duggan For a detailed analysis of the intersection of the role of disability and labor supply, see: “The Rise in the Disability Rolls and the Decline in Unemployment” David Autor and Mark Duggan (QJE 2003) Show that during recessions, the disability margin is much more relevant now than it was during the 1980s (the benefits to the disabled are now more comparable to unemployment benefits than before).

20
Non-employment Trends Throughout the Wage Distribution
21
Income or Substitution Effects?
22
Nonparticipation Trends Throughout the Wage Distribution
23
Longterm Nonparticipation Trends Throughout the Wage Distribution
24
Conclusions Decline in unemployment rate may not represent accurately the trends in labor market performance. Large decline in participation rates for men. Non employment has declined much less than unemployment. The decline is much more pronounced for low wage men. Does it tell us substitution effects are important? What about changes in transfers?

Part 3: Rug Rat Race and Time Investments in Children
26
Parental Time With Children By Education From Guryan, Hurst, and Kearney (JEP 2008) “Parental Education and Parental Time With Children”
27
Parental Time With Children By Education
30
More Facts Richer countries spend more time with children than poorer countries. Within countries, high educated parents spend more time with children relative to low education parents.

Part 4: Regional Dynamics
34
How Do Locations Respond to Local Shocks? Continue our theme about thinking about regional economics (house prices are one part of that). The direct mechanism:Mobility. What implications do mobility have on the response of labor supply, wages, and unemployment to local economic shocks? Some work: Blanchard/Katz (Brookings, ) Topel “Local Labor Markets” (JPE, 1986)
35
Consider the Following Labor Market (Inelastic Labor Supply) Labor Demand Labor Supply
36
Consider the Following Labor Market (Inelastic Labor Supply) Labor Demand Labor Supply In short run, adjustment takes place on wages (labor supply is less elastic in short run)
37
Consider the Following Labor Market (Inelastic Labor Supply) Labor Demand Labor Supply In long run, adjustment takes place on N (labor supply is more elastic in long run)
38
What is the Mechanism? In/out migration of workers…..

Blanchard/Katz Facts: VAR of Negative Regional Shock
58
Conclusions of Blanchard/Katz Regional Adjustments Take Place In short run, response occurs on unemployment and wage margins. In long run, it occurs on labor supply margin (via migration). Spatial equilibrium model has to make individuals indifferent to move across regions.
59
Part 5: Cross State Convergence
60
Cross State Convergence in Income Per Capita See a full discussion in Barro/Sali-Martin (Brookings, xxxx)
61
Convergence By Decades: 1940 – 1960
62
Convergence By Decades: 1960 – 1980
63
Convergence By Decades: 1980 – 2000?
64
Why Has Convergence Stopped? A great research question to think about Change in the skill premium? Chang-Tai Hseih and I are starting to put structure on this question How does changes in discrimination affect economic growth?
