Paying More to Get Less: The Effects of External Hiring versus Internal Mobility

Individuals often enter similar jobs via two different routes: internal mobility and external hiring. I examine how the differences between these routes affect subsequent outcomes in those jobs. Drawing on theories of specific skills and incomplete information, I propose that external hires will initially perform worse than workers entering the job from inside the firm and have higher exit rates, yet they will be paid more and have stronger observable indicators of ability as measured by experience and education. I use the same theories to argue that the exact nature of internal mobility (promotions, lateral transfers, or combined promotions and transfers) will also affect workers’ outcomes. Analyses of personnel data from the U.S. investment banking arm of a financial services company from 2003 to 2009 confirm strong effects on pay, performance, and mobility of how workers enter jobs. I find that workers promoted into jobs have significantly better performance for the first two years than workers hired into similar jobs and lower rates of voluntary and involuntary exit. Nonetheless, the external hires are initially paid around 18 percent more than the promoted workers and have higher levels of experience and education. The hires are also promoted faster. I further find that workers who are promoted and transferred at the same time have worse performance than other internal movers.

Do Women Choose Different Jobs from Men? Mechanisms of Application Segregation in the Market for Managerial Workers

This paper examines differences in the jobs for which men and women apply in order to better understand gender segregation in managerial jobs. We develop and test an integrative theory of why women might apply to different jobs than men. We note that constraints based on gender role socialization may affect three determinants of job applications: how individuals evaluate the rewards provided by different jobs, whether they identify with those jobs, and whether they believe that their applications will be successful. We then develop hypotheses about the role of each of these decision factors in mediating gender differences in job applications. We test these hypotheses using the first direct comparison of how similarly qualified men and women apply to jobs, based on data on the job searches of MBA students. Our findings indicate that women are less likely than men to apply to finance and consulting jobs and are more likely to apply to general management positions. These differences are partly explained by women’s preference for jobs with better anticipated work–life balance, their lower identification with stereotypically masculine jobs, and their lower expectations of job offer success in such stereotypically masculine jobs. We find no evidence that women are less likely to receive job offers in any of the fields studied. These results point to some of the ways in which gender differences can become entrenched through the long-term expectations and assumptions that job candidates carry with them into the application process.

What Happened to Long-Term Employment? The Role of Worker Power and Environmental Turbulence in Explaining Declines in Worker Tenure

Recent declines in the average length of time that U.S. workers spend with a given employer represent an important change in the nature of the employment relationship, yet it is one whose causes are poorly understood. I explore those causes using Current Population Survey data on the tenure of men aged 30–65, from the years 1979–2008. I argue that long-term employment relationships primarily occur when workers pressure employers to close off employment from market competition, reducing the attractiveness of external mobility relative to internal opportunities and increasing employment security. I then explore how two changes in organizations’ environments—a decline in union strength and increased turbulence from changes in technology and globalization—might have affected workers’ ability to secure such closed employment relationships over the last 30 years. My results support the argument that declines in tenure reflect the reduced power of workers to secure closed employment relationships. Recent declines in tenure have been concentrated in large organizations, and many of those declines are explained by controlling for the changing levels of industry unionization. I find little evidence that foreign competition or technological change affected mobility. The results are robust to measures of changing industry growth rates and within-industry reorganization. Supplementary analyses suggest that layoffs are associated with different industry pressures than tenure and that voluntary mobility may have played an important role in declines in tenure.

Shifts and Ladders: Comparing the Role of Internal and External Mobility in Managerial Careers

Employees can build their careers either by moving into a new job within their current organization or else by moving to a different organization. We use matching perspectives on job mobility to develop predictions about the different roles that those internal and external moves will play within careers. Using data on the careers of master of business administration alumni, we show how internal and external mobility are associated with very different rewards: upward progression into a job with greater responsibilities is much more likely to happen through internal mobility than external mobility; yet despite this difference, external moves offer similar increases in pay to internal, as employers seek to attract external hires. Consistent with our arguments, we also show that the pay increases associated with external moves are lower when the moves take place for reasons other than career advancement, such as following a layoff or when moving into a different kind of work. Despite growing interest in boundaryless careers, our findings indicate that internal and external mobility play very different roles in executives’ careers, with upward mobility still happening overwhelmingly within organizations.
