Introduction
The transition pattern of immigrants to a new labor market is characterized by high wage growth, fast decrease in unemployment as immigrants first find blue-collar jobs, followed by a gradual movement to white-collar occupations.
3
• Focus on - Acquisition of local human capital in: training, experience and local language.
• Data: quarterly labor mobility since arrival of high skilled male immigrants who moved from the former Soviet Union to Israel.
• Main macro facts.

Formulate a dynamic choice model for: • blue and white-collar occupations• training related to these occupations• Unemployment
Labor market opportunities are random and
are affected by characteristics, past choices
and language knowledge.
Participation in training is affected by: the
mean wage return, the job offer probabilities,
preferences and lost of potential wages.
7
Main Results• The estimated model fits well the main patterns of
the labor market mobility.• Return to training: white-collar 19%; blue-collar
13%, for 78% of population and zero for the rest.
• High return to local experience and language, but –conditional on local human capital - zero return to imported schooling.
• Main return to training is by the increase of 100% of white-collar offer probability.
8
Main Results (cont.)
• Individual welfare gain at arrival from training programs is 1-1.5%.
• Aggregate growth rate of wages from the availability of the government provided vocational training programs is .85 percent.
• Main reasons: return to experience is high and utility from participating in training is low (liquidity constraint).

• The model is solved using backward recursion with a finite linear approximated value at the 21’th quarter as function of Si21.
• We use Monte Carlo integration to numerically solve for the Value Functions and the probability of the choices jointly with the accepted wages.
• By simulations we show that the model can capture the main dynamic aspects of the labor market mobility as depicted by the figure.
17
Estimation Method
• The model is estimated using simulated maximum likelihood (SML) (McFadden(1989))
• Given data on choices and wage, the solution of the dynamic programming problem serves as input in the estimation procedure.
• All the parameters of the model enter to the likelihood through their effect on the choice probabilities and wages. Wages are assumed to be measured with error. M=2.

Fit results
• The estimated model fits well the pattern but a formal 2 test rejects the fit of the model.
• The 5’th year (20%)reduction in BC and increase in WC is explained by : Cohort and prior events (~10%); BC to WC transitions as unemployment reach minimum (~10%).

Offer Probabilities
• Large positive effect of training on WC offers and on BC offers
• Very Low WT opportunities P=0.037
• Very low offers for WC from BC and higher , but low from UE.
29
Interpretation of Types
• Type 2 have unobserved characteristics that fit well the Israeli labor market – easily receive offers and do not need training. (22%).
• Type 1 – need the training to adjust but the cost is high (utility ~ liquidity problem).
30
Policy analysis by Counterfactual Simulations
Structural estimation enables to simulate the effect of alternative policy interventions on the choice distribution, wages, unemployment and the discounted expected utility (PV).
Policy Choices: Case 1: No training is available. Case 2: Only training in blue-collar (BT) is available.Case 3: Only training in white-collar (WT) is available.Case 4: Double the probability to participate in WT.

Aggregate Wage Growth (Social Rate of Return)
• Aggregate wage growth is increasing overtime due to the permanent affect on job offers to WC.
• The social rate of return is above 1% mainly due to type 1 accepting WC jobs and type 2 BC jobs. Better process of job sorting.
• Double WT opportunities has a high (above 3%) social rate of return.

Conclusions
• The model provided a way to estimate the social and the individual rate of return from alternative training programs.
• Most of the gain from training is due to increasing WC job opportunities over long time.
• Large fraction of wage growth is due to occupational mobility, experience and language learning.
• The return to imported imported human capital is zero conditional on the locally accumulated human capital.
