1 The Value of Working Conditions in the United States
Kathleen J. Mullen, RAND Joint work with Nicole Maestas, David Powell, Till von Wachter and Jeffrey Wenger RRC Annual Meeting August 4, 2017 Funding from Sloan Foundation and MRRC/SSA gratefully acknowledged.

2 The Quality of Employment
Qualitative evidence of a gap between the jobs older workers want and the jobs available to them (e.g., Pitt-Catsouphes et al., 2015) Older workers say they desire: flexibility, meaningful work, pay and benefits, opportunities for advancement, supportive work environment, opportunity to gain transferable skills But do these gaps have quantitatively important effects on labor force participation? How important are working conditions?

3 Overview We conducted a series of Stated Preference choice experiments using the RAND American Life Panel to elicit valuations of job attributes We present estimates of total valuations based on incidence and compare to nominal wages to assess the importance of working conditions We also use these valuations to adjust wages to account for different working conditions in assessing different wage gaps Gender, Race, Education and Age

4 What Are Stated Preferences?
Provide hypothetical choices defined by observable attributes and prices Because observe full choice set, possible to estimate importance of each attribute relative to price Stated preferences have provided valuable evidence: Environmental policy (Carlsson and Martinsson, 2001) Consumer preferences (Revelt and Train, 1998) Labor supply (Kimball and Shapiro, 2010) Retirement decisions (Van Soest and Vonkova, 2014) Long-term care (Ameriks et al., 2015) CHECK REDUNTANT W/ DAVID?

5 Stated Preferences Research
Advantages: Observe full choice set Can account for differences across individuals Possible to study behavior in counterfactual situations Disadvantages: No incentive to choose accurately Salience of options may differ from similar choices in real world CHECK REDUNDANT W/ DAVID?

7 Stated Preference Estimates v. Compensating Differentials
Paid Time Off Flexibility Physical Demands Meaningfulness Autonomy Pace Training Telecommute Option Hours Work with Others Note Comp Diff/OLS estimates multiplied by -1 to put on same scale as SP—i.e., valuation. Interpretation of SP estimates: workers willing to give up 5.8% wage to get option to telecommute. Comp diff estimates are mostly wrong signed—e.g., you would have to give people 24.3% wage to get them to accept the option to telecommute.

8 How much do workers value working conditions overall?
To estimate the value of working condition, we plug estimates into utility function, equate utility with and without condition, and solve for amount that leaves worker indifferent We estimate, on average, workers value the 10 working conditions we study here collectively at 64% of their wage How does this vary by group?

16 Conclusion Stated Preference estimates imply, on average, workers value the 10 working conditions we study here collectively at 64% their wage Incorporating value of working conditions narrows gender wage gap, but widens gaps by race, education and age Valuation differences driven mainly by differences in preferences not incidence How to encourage older workers to stay in the labor force? Our results suggest understanding preferences for working conditions—not just incidence—is key.

18 Experimental Design Each respondent is first surveyed about their current/most recent job Then asked to choose their preferred job given a hypothetical choice set, 10x Job characteristics and wage are benchmarked to: For the first 8 pairs: their current/most recent job For the last 2 pairs: a common job observed among older workers nearing retirement For each choice, 2 dimensions are randomly chosen (w/o replacement) to vary, plus the wage Wages are multiplied by a normally-distributed random variable with mean 1 and variance 0.1

19 How do people value these dimensions?
Assume an indirect utility function: V(W,N)=α+βW+N´γ+ε, where W=wage, N=nonwage char. Assuming a set of possible job offers J, the probability of choosing job A is: P(V(WA,NA)>max over all V(W,N)) We don’t observe J in real life but we can simulate job choices to estimate β and γ using stated preference analysis

20 Stated Preference Analysis
Conduct a series of experiments where we ask people to choose between jobs. The probability of choosing between two jobs A and B is: P(job A>job B)=P(V(WA,NA)>V(WB,NB)) =P(β(WA-WB)+(NA-NB )´γ +εA-εB>0) Assuming a distribution for ε1-ε2, e.g., normal, then we can estimate β and γ by maximum likelihood
