Drawing from a social capital perspective, this study examines the psychological mechanism and boundary conditions of the relationship between individuals’ childhood economic status (CES) and later income. Specifically, we tested the mediating role of networking ability and the moderating role of encouragement of participation in this relationship. With a sample of 3635 employees in China and the use of multistage stratified sampling, the results indicate that networking ability mediates the CES and later income relationship. Moreover, encouragement of participation acts as a necessary condition in the relationship between networking ability and later income. Specifically, when encouragement of participation was high, increased networking ability was associated with increased later income. When encouragement of participation was low, the positive relationship between employees’ networking ability and later income was no longer significant. Finally, the indirect effect of CES on later income mediated by networking ability was stronger for organizations with a higher level of encouragement of participation. Findings and future directions in the theory and practice of career development are discussed.
- Career success
- Economic status
- Networking ability
- Encouragement of participation
There has been a long history of investigation into the antecedents of individuals’career success (Seibert, Crant, & Kraimer, 1999). As a critical indicator of career success, income has drawn excessive attention from researchers in the organizational behavior field for years, especially the examination of its predictors (Ng & Feldman, 2014), including proactive personality (Seibert, Kraimer, & Crant, 2001), political behavior (Judge & Bretz, 1992) and demographic variables such as gender (Ng, et al., 2005). As well, some researchers have been interested in the relationship between individuals’ early experience and their later income (Duncan et al., 1998). For instance, childhood economic status (CES) has been found to be a critical predictor of later income in a series of studies (e.g., Gibb, Fergusson, & Horwood, 2012; Hobcraft & Kiernan, 2001).
However, while the relationship between CES and later income is well established, the psychological processes underlying this relationship has been, however, poorly investigated. Prior research has not examined how individuals’ early economic status influences their cognition, attitudes and behavior, which in turn have an impact on their career success. In addition, boundary conditions of the CES-later income relationship has also not been adequately investigated, especially for organizational boundary conditions. There is a dearth of research examining the situation influence on the relationship between CES and later income in work settings. A deeper understanding of how and when CES has a stronger (or weaker) effect on later income will not only contribute to the literature on career development but also allow organizations to better promote individuals’ career success.
To address this void, the current study draws upon a social capital perspective (Lin, 1999, 2002) and tests the psychological mechanism and boundary conditions in the relationship between CES and later income. First, we conceptualize networking ability as a type of ability to accumulate social capital and test its mediating effect on the relationship between childhood economic status (CES) and later income to gain insight into the social capital-based mechanisms of this relationship. Moreover, by framing encouragement of participation as an advantageous environment for social capital building, and examining the moderating role of encouragement of participation in the CES-later income relationship, we aim to demonstrate that the effect of CES on later income through networking ability is not universal across all organizations, but depends on the level of encouragement of participation in that organization. The investigation of boundary conditions would not only answer the question as to whether the impact of employees’ networking ability on their career success depends on organizational conditions, but also helps us to gain a better understanding of the contingent nature of the CES-later income relationship.
Theoretical foundation and hypothesis development
Mediating role of networking ability
Networking ability refers to individuals’ ability to build and maintain large and strong social networks (Burt, 2009). While the network they build contains some influential others, employees with high networking abilities are expected to possess information asymmetries (Burt, 2009), be connected to significant others and be in a position to generate and receive more opportunities (Pfeffer, 1992), which will help them achieve their goals (Ferris et al., 2007, 2008; 2012). Of the four dimensions of political skills (i.e., networking ability, social astuteness, interpersonal influence, and apparent sincerity), networking ability was found to be the strongest in predicting career and organizational outcomes (Todd et al., 2009). For example, networking ability was found to be the only predictor of employees’ total compensation among four political skill dimensions (Ferris et al., 2008; Todd et al., 2009). Thus, from the perspective of individuals within the social network, it is of great importance for them to have the ability to network and use it to construct a network that is beneficial to their career success (Thompson, 2005).
Hypothesis 1: Networking ability mediates the positive relationship between CES and later income.
Moderating role of encouragement of participation
Since networking ability is characterized by social effectiveness (Blickle et al., 2009), environmental factors may play a key role in affecting the impact of networking ability on career outcomes. However, to date, few studies have tapped into the contextual influence in the networking-career success relationship. Based on social capital theory (Lin, 1999, 2002; Nahapiet et al., 1998), resources or capital are embedded within relationships, which is created through exchange with others (Bourdieu, 1986). Since the exchange does not happen in a vacuum but in real organizational settings, situational factors affecting the quality and quantity of exchange, such as the encouragement of participation (Sun et al., 2007), may have an impact on the accumulation of social capital.
Encouragement of participation, which refers to the degree that the organization encourages employees to make decisions on their own work and participate in decisions regarding the organization (Bamberger, Biron, & Meshoulam, 2014; Bamberger & Meshoulam, 2000; Sun et al., 2007), is a typical organizational condition that promotes leader-subordinate exchange. Thus, we conceptualize encouragement of participation as creating an advantageous environment for social capital accumulation. Organizations with a high level of encouragement of participation provide employees with opportunities to have smooth communication with leaders and give suggestions to improve their performance (Bamberger et al., 2014; Bamberger & Meshoulam, 2000; Sun et al., 2007). From a social capital perspective (Lin, 1999, 2002), networking processes require employees to connect to influential people and be in a position where it is easy to generate and receive opportunities (Pfeffer, 1992). A high level of encouragement of participation would provide a favorable environment for employees to exert influence and receive opportunities. Thus, employees with a high level of encouragement of participation are more likely to utilize their ability to network to achieve career success (e.g., high income) than in a low-participation environment. Therefore, we propose that encouragement of participation will moderate the relationship between employee networking ability and later income. Specifically, when encouragement of participation is high, an increase in networking ability will be associated with increased income. When encouragement of participation is low, the positive relationship between networking ability and income will be attenuated.
Hypothesis 2: Encouragement of participation moderates the relationship between employees’ CES and their later income mediated through networking ability. Specifically, the positive relationship between networking ability and later income is stronger when encouragement of participation is high.
Participants and procedures
We collected data from a national survey program for human resources management in China. The content of the survey includes questionnaires on human resources management, labor relations and social security. The survey program was implemented in 12 cities across the country. The selection of cities was based on geographical distribution and population. Next, the survey program selected companies through two-step stratified random sampling from companies listed in the Index of the National Companies in China 2008 and located in the 12 cities. In the first step, 36,000 companies in 12 cities were randomly selected. In the second step, 444 of the 36,000 companies were randomly selected to administer the survey to their 4532 employees. Finally, 3635 employees completed the whole survey, with a response rate of 80%. Among the 3635 participants, 1978 were female (54.4%), 1657 were male (45.6%), the average age was 33.39 (SD = 9.35), 28.7% of them had a college degree, and 24.4% of them had a bachelor degree or above. The majority of the participants (57.0%) were front-line workers, 24.6% were business or technical staff, and 18.4% were managers.
Childhood economic status
CES was measured by one item question about the participants’ socioeconomic status at the age of 14. The question is “How was your family income comparing to the average level when you were 14?”. Participants were asked to rate their answer on a 5-point scale (1 = significantly worse than average, 5 = significantly better than average).
Later income was measured by employees’ self-reported annual income using two items, which were “How much was your salary last year” and “How much did you receive in supplementary income (e.g., bonuses, profit-sharing, awards) last year?” The later income was obtained by the sum of the respondent’s scores for the two items. A self-reported measure of income, which has been shown to have a high correlation with organization records (Dreher, 1977), can be a valid measure of income for this study.
Networking ability was measured by the networking ability dimension of Ferris et al.’s (2005) 18-item political skill scale. Participants were asked to rate their agreement about their networking ability on a 5-point scale (1 = strongly disagree, 5 = strongly agree). A sample item is “I spend a lot of time and effort at work networking with others.” Higher scores represent a higher ability in networking. Cronbach’s α for networking ability was 0.78.
Encouragement of participation
Encouragement of participation was measured by the 4-item participation dimension of the high-performance human resource practice scale (Sun et al., 2007). Respondents were asked to rate their agreement with statements related to their perceived encouragement of participation within the organization on a 5-point scale (1 = strongly disagree, 5 = strongly agree). The items are: “Employees in this job are often asked by their supervisor to participate in decisions”; “Individuals in this job are allowed to make decisions”; “Employees are provided the opportunity to suggest improvements in the way things are done”; and “Supervisors keep open communications with employees in this job”. Higher scores represent a higher level of encouragement of participation. Cronbach’s α for encouragement of participation was 0.80.
Participants’ demographic characteristics, including gender (1 = male, 2 = female), age, education level (1 = illiteracy, 2 = primary school, 3 = middle school, 4 = high school, 5 = technical secondary school, 6 = college, 7 = bachelor, 8 = master or above), tenure (measured in years), job position (1 = front-line workers, 2 = business or technical staff, 3 = managers) and nature of the organization they belong to (1 = stated-owned company/ public sector, 2 = private firms), were measured as control variables.
To examine the role of encouragement of participation in the relationship between networking ability and income, we adopted the “second stage moderation model”approach (Edwards & Lambert, 2007), which refers to the model with a moderating effect on the second path of the indirect effect of the independent variable on the dependent variable through the mediator. In our model, networking ability plays a mediating role in the relationship between CES and later income, and encouragement of participation moderates the path from networking ability to later income. Thus, there is a conditional indirect effect of CES on later income at different levels of encouragement of participation. We used Model 14 (second stage moderated mediation model) from Hayes’ (2013) PROCESS macro in SPSS to complete the data analysis.
To ensure the discriminant validity of the self-rated variables (networking ability and encouragement of participation), a confirmatory factor analysis (CFA) was performed using Mplus 7 (Muthén and Muthén, 1998–2012). The two-factor model (i.e., both variables are independent of each other) provided a generally good fit to the data, with χ 2 (26) = 698.84, p < 0.01, comparative fit index (CFI) = 0.93, Tucker-Lewis index (TLI) = 0.90, and root-mean-square error of approximation (RMSEA) = 0.08. According to the chi-square difference tests, the two-factor model fit the data significantly better than the one-factor model (i.e., combining Networking ability and Encouragement of participation for active divergence), χ 2 (27) = 3966.56, p < 0.01, CFI =0.57, TLI = 0.43, and RMSEA = 0.20. Thus, the discriminant validity of the study variables was supported.

Hypothesis 1 proposed that networking ability mediates the CES-later income relationship. We examined the mediating effect of networking ability using Model 4 (mediation model) from Hayes’ (2013) PROCESS macro in SPSS. With the bootstrapping of 5000 re-samples, the results show that the indirect effect of CES on later income through networking ability is significant (Estimates = 0.11, SE = 0.04, p < 0.05, 95% confidence interval (CI) = [0.04, 0.21]). After controlling for employees’ gender, age, educational level, tenure, job position and nature of organization, the indirect effect of CES on later income through networking ability is still significant (Estimates = 0.05, SE = 0.03, p < 0.05, 95% confidence interval (CI) = [0.00,0.12]). Thus, Hypothesis 1 is supported.

Contribution of the study
By examining the mechanisms and moderators of the effect of CES on later income, the current study has made several contributions to theory and practice in career development and organizational behavior. Firstly, given the importance of the research of intergenerational income mobility (Solon, 1992) and deficient investigation of the psychological mechanisms of the relationship between CES and later income, the findings of the current study, which demonstrate that networking ability acts as a mediator, provide us a new possible route to understanding the CES-later income relationship. Second, the present study identifies encouragement of participation as a boundary condition in the networking ability-career success relationship and furthers the relationship between CES and later income mediated by networking ability. It is worth noting that normal and above-level encouragement of participation in organizations is a necessity for high-CES and networking ability employees to gain more income than their low-CES and networking ability colleagues. Under low levels of encouragement of participation, the positive relationship between networking ability and income becomes non-significant.
These findings are consistent with social capital theory (Lin, 1999, 2002), which posits that social capital is accumulated through exchange relationships. Individuals with high CES find it easier to develop and obtain a high level of networking ability, which in turn helps them accumulate more social capital and gain more career success. However, while a low level of encouragement of participation hinders employees from the exchange with coworkers and leaders, the efficacy of networking on social capital acquirement will be impaired. Without sufficient social capital, the career development (such as compensation growth) of even high CES employees will be impeded. Encouragement of participation here acts as an environmental requirement for employees to give full play to their networking abilities, part of which is derived from their CES.
The current study also contributes to the research and application of high-performance human resource practice (Bamberger et al., 2000; Sun et al., 2007). Although Sun et al. (Sun et al., 2007) claimed that high-performance human resource practice contains six sub-dimensions and encouragement of participation is one of the sub-dimensions, they had not examined the effect of its sub-dimensions on organizational and individual outcomes. The current study is the first to examine the situational influence of the encouragement of participation in career research. The findings of the moderating role of encouragement of participation in the networking ability-later income relationship will promote our understanding of the impact of organizational policy on individual career development.
Limitations and future directions
Although the current study contributes to the literature in several ways, there are certain limitations that should be noted in the present investigation. First, though the present study has a large sample of 3635 employees using multistage stratified sampling to examine the predicting effect of employees’ CES on their career success and the mechanisms and moderators of this effect, the using of cross-sectional data limits the conclusions about the effect’s direction and duration and may lead to common method bias. Future research should address this concern and use a time-lagged study design to give stronger evidence of the study effect.
Second, the current study only measures total compensation as a career success indicator. Although compensation acts as one of the most critical and objective elements of career success (Seibert et al., 1999), there are still other objective elements (i.e., promotion) and subjective elements (i.e., career satisfaction and life satisfaction) of career success that deserve further investigation. Future research could address this point, and the results will provide a complete picture of the interactive effect of networking ability and encouragement of participation on career success. Further, only one item was used to measure CES. Future research could use additional items to ensure the validity of CES measurement. In addition, future studies could also incorporate more control variables reflecting individuals’ sociological status other than CES into the research model to better capture the unique effect of CES on career success.
Third, drawing upon social capital theory (Lin, 1999, 2002), we argue that networking ability mediates the relationship between CES and later income. Although the hypothesis was supported, much further work is needed into the investigation of the psychological mechanisms of the CES-later income relationship. For example, future research could draw from the interactionist perspective (Terborg, 1981) and examine the role of proactive personality in the CES-later income relationship. It will be even better to simultaneously consider multiple paths of mediation and examine which path could explain more variance. By doing so, the present study will shed light on the research of the mechanism of the CES-later income relationship and intergenerational income mobility.
The present study also has some practical implications for individual career development. Firstly, although an individual’s later income is influenced by his/her childhood economic status, which seems to demonstrate low intergenerational mobility, this influence is not direct but through the effect of networking ability. The finding that the impact of CES on later income is mediated by networking ability provides critical knowledge for organizations that aim to promote intergenerational mobility. Organizations may treat networking ability as a key intervention point to help individuals from low CES households to increase their later income. Specifically, by providing training and a favorable environment to develop individuals’ networking ability, their income level in the future will be increased, especially for those low CES individuals.
Second, although previous research has demonstrated that individuals who have a high level of networking ability will be more likely to succeed in performing job tasks and obtain higher income throughout their career (Ferris et al., 2012; Todd et al., 2009), the findings in the current study raises the concern of contextual influence in the networking ability-career success relationship. Individuals should not only focus on their networking abilities but also pay attention to the climate of encouragement of participation in the organization. Without the organization’s support for employee participation, high networking ability employees will not be able to fulfill their capacity. From the organizations’ point of view, organizations should provide an environment that encourages participation to fully free up individuals’ potential for networking. Specifically, organizations could ask employees to participate in management decisions and provide opportunities for employees to suggest improvements in their work. This will help employees to better utilize their networking abilities and in turn, would lead to individuals’ higher income levels and career success.
In summary, the current study draws upon social capital theory (Lin, 1999, 2002) and investigates the mechanisms and contextual moderators of the relationship between CES and later income. The results suggest that networking ability mediates the relationship between CES and later income. In addition, the path of CES to later income via networking ability is stronger when encouragement of participation is high. On the other hand, when encouragement of participation is low, the positive relationship between CES and later income mediated by networking ability is no longer significant. With these findings on the mechanisms and moderators of the CES-later income relationship and suggestions for future directions, the current study sheds some light on the research of intergenerational income mobility.
