2 8-2 Introduction Labor mobility is the mechanism labor markets use to improve the allocation of workers to firms.

3 8-3 Geographic Labor Migration as an Investment in Human Capital Mobility decisions are guided by comparing present value of lifetime earnings among alternative employment opportunities in different locations.

4 8-4 Geographic Labor Migration as an Investment in Human Capital A worker decides to move if the net gain from moving is positive. Migration occurs when there is a good chance the worker will recoup his investment in the move.

5 8-5 Internal Migration in the U.S. There is a positive correlation between a worker ’ s educational attainment and the probability of migration. Workers that have migrated are likely to return to the location of origin (return migration) and are more likely to migrate again (repeat migration).

6 8-6 Worker mobility movement from one job to another. this may involve geographical changes, and/or movement from one employer to another.

7 8-7 Benefits and costs of mobility psychic costs and benefits are included as well as direct costs and benefits. costs and benefits include: –friendships with co-workers and members of the community, –family ties, –working environment, –non-pecuniary job benefits, and –characteristics of geographical locations

8 8-8 Geographic mobility more strongly affected by the “pull” from the destination than by the “push” from the original location. young workers are more likely to move. married workers are less likely to move. most moves are within county and state boundaries. chain migration is a common phenomenon in international migration.

9 8-9 Immigration and employment immigration increases labor supply in some labor markets. immigration raises labor demand in all labor markets. domestic employment (and wages) will fall in those labor markets in which labor supply rises by more than labor demand.

10 8-10 Family Migration The optimal choice for a member of the family may not be optimal for the family unit (and vice versa). –Tied stayer: someone who sacrifices better income opportunities elsewhere because the partner is better off in the current location –Tied mover: someone who moves with the partner even though his or her employment outlook is better in the current location.

11 8-11 The Decision to Immigrate Skills vary across country-of-origin (or source country) immigrant groups. The general rule: Workers decide to immigrate if earnings exceed earnings in the source country. –The decision ultimately depends on individual skills and the returns to those skills in the source and destination countries.

12 8-12 The Roy Model The Roy model considers the skill composition of workers in the source country. –Positive selection: immigrants who are very skilled do relatively well in the U.S. –Negative selection: immigrants who are unskilled do relatively well in the U.S. –The relative return to skills determines the skill composition of the immigrants from different source countries.

13 8-13 Policy Application: Economic Benefits of Migration The immigrant surplus is a measure of the increase in national income that occurs as a result of immigration. (The surplus accrues to natives.) Immigration raises national income by more than it costs to employ immigrants.

14 8-14 Job Turnover: Stylized Facts Newly hired workers tend to leave their jobs within 24 months of being hired, while workers with more seniority rarely leave their jobs. The rate of job loss is highest among the least educated workers

15 8-15 Job Turnover: Stylized Facts There is a strong negative correlation between a worker ’ s age and the probability of job separation. –This fits with the hypothesis that labor turnover can be an investment in human capital.

16 8-16 Specific Training and Turnover When a worker receives specific training, his productivity improves only at the current firm. This implies there should be a negative correlation between the probability of job separation and job seniority.

17 8-17 Determinants of turnover workers who receive a lower wage are more likely to quit. firms that offer lower wages have higher quit rates. women have higher quit rates. job quits increase during expansions and fall during recessions.
