    The relationship between perceivedcompensation, organizational commitmentand job satisfaction: the case of Mexicanworkers in the Korean Maquiladoras

    Yongsun Paik, K. Praveen Parboteeah and Wonshul Shim

    Abstract Expatriate literature has generally favoured home country factors tounderstand expatriate success. In this paper, we contribute to the field by shifting ourfocus to the host country workforce (HCW). We use equity theory to examine the effectsof perception gaps in compensation between HCW and expatriates on organizationalcommitment and its impact on job satisfaction and job performance. Based on field surveysand in-depth interviews of Korean expatriates as well as Mexican workers, results providesupport for our hypothesis that significant perception gaps exist in compensation. Thefinding that compensation gap was significantly related to affective commitment only is ofcrucial importance. Our results also suggest that only affective commitment is positivelyrelated to job satisfaction and performance. We discuss research as well as managerialimplications.

    Keywords Perception gaps; organizational commitment; expatriates.

    Introduction

    International human resource management research continues to focus scholarly

    attention on expatriates (e.g. Mezias and Scandura, 2005; Toh and Denisi, 2003).

    Extensive research efforts have yielded important understanding of the expatriate

    experience and solutions to ensure that these experiences occur as smoothly as possible

    (Harzing, 2002; Tung, 1987). As such, research on expatriate management has focused

    mostly on the role of headquarters and the home unit at the expense of understanding the

    host country workforce (HCW) and the host company (Suutari and Burch, 2001; Vance

    and Paik, 1995, 2002; Vance and Ring, 1994). However, although much research agrees

    that expatriate success is heavily dependent on the HCW (e.g. Jassawalla et al., 2004;

    Toh and Denisi, 2003), there has been a relative neglect of scholarly attention paid to

    these HCW. This paper answers the call to give greater research attention to the HCW(Aycan and Kanungo, 1997; Toh and Denisi, 2003).

    It is crucial to get a better understanding of HCW perspectives, since HCW play a key

    role in ensuring that the expatriate experience runs smoothly (Toh and Denisi, 2003).

    HCW provide expatriates with important socialization support, assistance and

    friendship in an unknown environment (Caligiuri and Cascio, 1998). Additionally,

    Jassawalla et al.(2004) argue that one of the most important determinants of expatriate

    adjustment is how they deal with cross-cultural conflicts with HCW. Those expatriates

    who benefit from such HCW actions are more likely to experience a better adjustment to

    their work situation. It is, therefore, critical for expatriates to gain support from the HCW

    if they want to perform at the best level.

    Although HCW perceive significant unfairness due to compensation gaps (Chenet al.,

    2002), no study has yet investigated the effects of the perceived compensation gap on the

    MNCs subsidiary and HCW (for a conceptual discussion of this issue, see Toh and

    Denisi, 2003). Specifically, our research question addresses whether HCW indeed

    perceive a compensation gap, as it has important implications for HCWs awareness ofjustice and fairness (Lemons and Jones, 2001). We also investigate how this perception

    gap influences their level of organizational commitment and their job satisfaction and

    performance. Extant theories (e.g. equity theory, Adams, 1965) suggest that people have

    a natural tendency to compare themselves with other social referents. Recognizing that

    expatriates are also important social referents (Chen et al., 2002), it is likely that the

    HCW will compare themselves with the expatriates and perceive lower compensation.

    We further argue that HCW will redress such inequity through their affective and

    continuance commitment (Allen and Meyer, 1990) to the organization. Furthermore,

    consistent with previous literature (Mathieu and Zajac, 1990), we also examine how

    these forms of organizational commitment are related to job satisfaction and job

    performance.

    We believe that the present study makes important contributions to expanding the

    literature on both expatriates and HCW. First, we address the relative dearth of HCW

    scholarship (Toh and Denisi, 2003) by focusing our attention on such workers. Second,we examine the effects of perception gap in compensation on organizational

    commitment, in other words, the relative strength of an individuals identification and

    involvement in an organization (Mowday et al., 1979: 226). Considerable research has

    been conducted on organizational commitment and job satisfaction as individual or

    organizational outcomes mostly in the domestic setting (e.g. Bateman and Strasser,

    1984; Mathieu and Zajac, 1990; Riketta, 2002). Few studies, however, have examined

    the relationship between compensation gaps and organizational commitment and the

    latters impact on job satisfaction and job performance, particularly in the context of

    expatriates managing a foreign workforce. Therefore, our research fills this important

    void in the literature. Third, the current research helps enhance our understanding of the

    influence of perceptions of unfairness and its consequences for the organization, which

    are more important predictors of behavioural manifestations (e.g. intent to turnover)

    than other core work attitudes (Dailey and Kirk, 1992). Finally, unlike existing studies

    that mainly focus on US- or Western-based expatriates, our study is novel in that we

    consider the case of South Korean companies operating in Mexico. Our study is based

    on in-depth interviews and a survey questionnaire of Korean expatriates and the

    Mexican workforce. While South Korean MNCs such as Samsung and Hyundai have

    emerged as global competitors, research on their international human resource

    management (IHRM) practices is sparse (Paik and Sohn, 1998). The results from this

    study will help us better understand the IHRM practices of these new global

    competitors.

    Perception gaps, organizational commitment and job performance

    Previous research reports that HCW tend to receive significantly lower compensation

    than expatriates (Reynolds, 1997). This is not surprising given the significant

    compensation inducements and benefits (i.e. cars, club memberships, etc.) that are given

    to encourage expatriates to accept foreign responsibilities (DeLisle and Chin, 1994).

    Chenet al.(2002) argue that compensation packages for US expatriates tend to be two to

    five times more than what the home country counterparts are receiving and much higher

    than the HCW. Furthermore, such compensation gaps are viewed as natural and

    inevitable because of the many hardships (cultural adjustment, family displacement) that

    expatriates face when they decide to take on such foreign assignments.

    We argue that HCW workers are likely to perceive lower compensation compared to

    expatriates. Equity theory (Adams, 1965) provides the theoretical basis for our

    proposition it has received widespread support in both domestic and international

    contexts as an intellectual foundation for perceived unfairness and consequences fororganizations as well as individuals (e.g. Chen et al., 1998, 2002; Miles et al., 1994;

    Scheer et al., 2003).

    A basic premise of equity theory is that individuals have a natural tendency to compare

    themselves with others based on the ratio of their outcome (e.g. pay) to input (e.g. work

    effort) (Adams, 1963, 1965).However, an importantfacet of equity theory is the choice of

    referent others for comparison (Kulik and Ambrose, 1992). Toh and Denisi (2003) argue

    that HCW are likely to view expatriates as social referents because expatriates tend to be

    viewed as a salient outgroup category on the basis of national identity. As several

    nationalities tend to interact within the MNCs, national identities become naturally more

    relevant, often invoking an us versus them mentality among HCW (Toh and Denisi,

    2003). Thus, expatriates become a salient referent for HCW. Furthermore, Kulik and

    Ambrose (1992) contend that dissimilar others (e.g. expatriates) can be considered as

    social referents as long as theyare somewhat relevant and compensation information about

    the referent is readily available. Given that compensation and benefits for expatriates areoften publicly known by HCW, and that expatriates often interact with HCW, expatriates

    are likely to be considered as social referents. Furthermore, when expatriates are from

    more developed countries, they are likelyto getmuch highercompensation andpremiums

    (Harvey,1993). Such wide disparities are likely to magnify thepresenceof two subgroups

    and encourage HCW to consider expatriates as relevant referents.

    Given the above expectations that HCW compare themselves with expatriates, it is

    likely that they will perceive lower compensation than expatriates. Therefore, we propose:

    Hypothesis 1: HCW perceive lower compensation compared to expatriates.

    Perception gaps and organizational commitment

    Organizational commitment refers to the relative strength of an individualsidentification and involvement in a particular organization (Steers, 1977). In this

    paper, we consider two organizational commitment components that have received

    substantial research attention, namely affective and continuance commitment (Glazer

    et al., 2004). Affective commitment is the emotional attachment and identification with

    ones organization (Allen and Meyer, 1990). Continuance commitment refers

    to commitment based on the employees attitude towards leaving the organization.

    In general, an employee with high continuance commitment is less likely to leave the

    organization because of costs involved with such a move.

    1770 The International Journal of Human Resource Management

  • 8/14/2019 ijhrm.pdf

    4/15

    We propose that there is a negative relationship between the compensation gap HCW

    perceive relative to expatriates and the two components of organizational commitment.

    We base our proposition on equity theory (Adams, 1963, 1965) which prescribes that if

    people feel that they are receiving less reward relative to their work efforts compared to

    others in the organization, they are likely to perceive inequity and unfairness. We argue

    that as HCW will compare themselves with expatriates, they will perceive inequity and

    unfairness. Equity theory further suggests that if unfairness is perceived, the concerned

    individuals will try to find ways to correct the perceived inequity by adjusting the

    outcome/input ratio (Adams, 1965).

    Several arguments can be advanced to expect the Mexican HCW to use expatriates as

    referents for basis of comparison. First of all, Toh and Denisi (2003) suggest that HCW

    have a natural tendency to simplify their environment and will categorize expatriates as

    out-groups. In such cases, because of differences of nationalities, Mexican HCW are

    likely to see South Koreans as us versus them. Second, the high power distance ofMexican culture (Hofstede, 2001) will also accentuate the salience of the out-group. High

    power distance suggests that the Mexican HCW tend to expect that their expatriate

    supervisors are authoritarians, further emphasizing that they are out-groups. As a result,

    Mexican workers are very likely to see these expatriates as their relevant referents.

    Additionally, with the emphasis on power distance, it is likely that the expatriates will

    isolate themselves from HCW thereby increasing their salience. Finally, distinctiveness

    theorists (e.g. McGuire, 1984) also suggest that differences in physical characteristics

    and appearance may form the basis for social categorizing. Given that South Koreans are

    physically very different in skin tone and other very noticeable features from Mexicans,

    they are very likely to be seen as a distinctive out-group. Furthermore, the salience of the

    expatriates is also enhanced if they come from a culturally distant country (Toh and

    Denisi, 2003).

    Based on the above, we argue that the Mexican HCW will see South Korean

    expatriates as a salient referent and will compare their compensation to the expatriatesand perceive inequity. Then, in an effort to correct the inequity, it is likely that the HCW

    will find ways to either decrease their input or to increase their output. Since both

    affective and continuance commitment are considered important components of the

    employees input, a possible means for HCW to reduce perceived inequity is to be less

    committed to the organization (i.e. reduce the input).

    Existing research suggests that affective commitment develops as employees

    experience positive treatment by their organizations (Meyer and Allen, 1988; Ogilvie,

    1986) and that a positive relationship exists between organizational commitment

    and fairness in the organization (Dailey and Kirk, 1992; Greenberg, 1990; Sweeney and

    McFarlin, 1993). This means that commitment develops as a result of experiences that

    satisfy employees needs and/or are compatible with their values (Steers, 1977).

    The positive treatment is often experienced through employees exchange

    relationship with their management in the form of compensation. However, if a

    significant perception gap exists between the employees who receive experiences and

    the expatriates who provide them, it is unlikely that HCW regard their work

    environment positively. Accordingly, if HCW have more negative experiences because

    of the perceived gaps, they are less likely to be affectively committed to the

    organization. Furthermore, this gap could even be magnified when the two parties are

    from distinctive cultural backgrounds and HCW see expatriates as us versus them.

    This perceived gap may also reduce the employees desire to stay with the organization.

    Therefore, we propose:

    Y. Paiket al., Perceived compensation, . . . and job satisfaction 1771

  • 8/14/2019 ijhrm.pdf

    5/15

    Hypothesis 2a: The compensation gap between HCW and expatriates is negatively

    related to affective commitment.Hypothesis 2b: The compensation gap between HCW and expatriates is negatively

    related to continuance commitment.

    Organizational commitment, job satisfaction and performance

    Previous research (e.g. Cullen et al., 2002; Mathieu and Zajac, 1990; Allen and Meyer,

    1990) shows that the positive relationship between organizational commitment and job

    satisfaction is a key, consistent finding. It is typically assumed that job satisfaction will

    lead to organizational commitment (e.g. Bluedorn, 1982; Koch and Steers, 1978). This

    assumption is based on the logic that the more satisfied employees are with their jobs, the

    more likely they are to develop the necessary attachment to the organization and

    develop a stronger commitment.

    Mathieu and Zajac (1990), however, argue that the causal order between jobsatisfaction and organizational commitment may not necessarily be as has traditionally

    been assumed. In fact, in a longitudinal study, Bateman and Strasser (1984) found that

    organizational commitment is possibly an antecedent of job satisfaction. We adopt this

    position and also argue that organizational commitment is a precursor to job satisfaction.

    An employee may be committed to an organization because he/she identifies with

    the organizational values as reflected in the corporate culture. Such attachment to the

    organization will result in higher job satisfaction. In contrast, those employees who are

    less committed to their organization are less likely to be satisfied with their jobs.

    Previous studies suggest that there is a moderate but positive relationship between

    organizational commitment and job performance (Mathieu and Zajac, 1990; Randall,

    1990). However, Riketta (2002) argued that the low correlations found between

    commitment and performance may be due to methodological issues (i.e. researchers did

    not consider all three components of commitment; samples are too restricted or too

    comprehensive). Her meta-analysis does indeed show that there is a stronger and positive

    relationship between affective commitment and job performance (Riketta, 2002). We

    also agree that a significant and positive relationship exists between organizational

    commitment and job performance. Those HCW who are more attached to the

    organization are more likely to work harder and thus achieve stronger performance.

    Thus, we propose:

    Hypothesis 3a: A positive relationship exists between HCW organizational

    commitment and job satisfaction.Hypothesis 3b: A positive relationship exists between HCW organizational

    commitment and job performance.

    Method

    Sample

    Ten Korean firms in export-oriented industries (industria maquiladora) in Mexico

    participated in the current study. Nine firms are in the consumer electronics industry and

    one firm is in the clothing industry. The firms are located in varied areas throughout

    Mexico including Tijuana, Mexicali, Mexico City, Colorado SL and Puebla. Mexico was

    selected as a host country because the conclusion of the North American Free Trade

    Agreement (NAFTA) has made Mexico increasingly attractive as a viable location for

    foreign direct investments (FDI). Inflow of FDI continues to increase since the inception

    1772 The International Journal of Human Resource Management

  • 8/14/2019 ijhrm.pdf

    6/15

    of NAFTA in 1994. In turn, Korea has been one of the fastest growing East Asian

    investors in Mexico, using the country as both a manufacturing and a marketing platform

    to take advantage of the more integrated North American market. With Korean

    companies rapidly globalizing, it has become more and more critical for them to manage

    effectively the local workforce to achieve the preferred outcome (Paik and Sohn, 1998).

    The research team combined two different methods to collect data. One

    group conducted in-depth interviews with four to five Korean expatriate managers as

    well as two to three Mexican managers per firm to collect qualitative data. Each

    interview lasted two hours on average. The other group conducted field survey studies

    with Mexican employees to collect quantitative data. Korean managers also participated

    in this survey. Our intention for conducting the interviews was to use the results as

    complementary data to corroborate our findings of the field survey.

    Respondents

    Forty-five Korean expatriates voluntarily agreed to participate in the survey and all of

    them returned the questionnaire. Five hundred and fifty-one local Mexican employees

    participated in the survey. The unusually high return rate was possible because

    the participating firms announced the survey opportunity and promised volunteering

    employees with a full hourlywage paid forthe time they spent to fillout the questionnaire.

    Among the participating employees, 62.2 per cent were male and 37.8 per cent were

    female; 77.8 per cent were workers and 22.2 per cent were supervisors; 45.7 per cent

    completed regular education for 12 years or more and 54.3 per cent were educated for less

    than 12 years. To achieve the compatibility between the two groups of respondents, we

    only used the responses from Mexican managers and supervisors in our statistical

    analyses.

    Measures

    Similar to Chen et al.(2002), we first asked the local Mexican employees to evaluate how

    they thought their companies treated them as compared to the Korean expatriates. Our

    intention was to find out the employees perception about their rewards system relative

    to that of Korean expatriate managers. For example, the question read, How do you

    perceive your compensation? and the employees were asked to check one from among a

    five-point scale of answers such as much better than average, better than average,

    average, below average and poor. Questions were also asked for ratings of

    education opportunities, promotability and technical skills acquisition. These

    independent variables were selected through interviews with Korean repatriates and from

    the findings of the existing literature (e.g. Delery and Doty, 1996). They were included as

    control variables to avoid any spurious relationships with organizational commitment.

    Then, the same set of questions was asked of the Korean expatriates. Our intention was to

    compare the perception of the Mexican managers compensation between themselves

    and the Korean expatriates.We note that we did not explicitly ask the Mexican workers to compare themselves

    with the South Korean expatriates as they rate compensation and other elements of the

    work environment. We reasoned that there would be obvious gaps if the Mexican

    workers were asked questions comparatively. In other words, if the HCW were asked to

    rate their compensation relative to expatriates, they would likely rate those as lower. By

    asking the HCW to rate their compensation independently of expatriates without

    identifying the social referent in the survey, we believed that we would be able to control

    the response bias more effectively.

    Sixteen items were used to assess the level of organizational commitment of Mexican

    employees, which were used as both independent and dependent variables. In the

    current study, we decided to use an organizational commitment instrument that

    Allen and Meyer (1990) developed. Different from Mowday et al.s (1979) widely

    used organizational commitment questionnaire (OCQ), Allen and Meyer conceptualized

    organizational commitment into three components: affective, continuance and

    normative organizational commitment (Meyer and Allen, 1991). Affective organiz-

    ational commitment refers to the employees emotional attachment to, identification with

    and involvement in the organization. It basically captures the desire to

    keep membership in the organization. Meanwhile, continuance commitment refers to

    an awareness of the costs associated with leaving the organization. In other words,

    employees with strong continuance commitment remain in the organization because they

    need to do so. Only affective and continuance commitments were used in this study since

    the notion of normative commitment has either not been stable or has been consistently

    measured (Morrow, 1993). Using a five-point scale, eight items were prepared to

    measure affective commitment and eight items were also developed to measure

    continuance commitment.

    We also measured performance as another dependent variable (quality, quantity,

    speed, accuracy, performance by company standard and performance relative to peers),

    on a five-point scale: well above average, above average, average, below average

    and well below average. We also used job satisfaction as a dependent variable on a five-

    point scale. Job satisfaction represents the most widely studied behavioural correlate of

    organizational commitment in the existing literature (Mathieu and Zajac, 1990).

    Results

    A test of reliability on the entire 16-item survey revealed a Cronbach alpha coefficient

    of .78, indicating very high instrument reliability. First, to test Hypothesis 1, one-wayANOVA was used to detect any significant differences between Mexican HCW and

    Korean expatriates in terms of compensation. Significant differences of perception were

    found in compensation as Korean management rated compensation as above average

    while Mexican employees rated them as below average (See Table 1). These results

    provide support for Hypothesis 1.

    Next, using varimax rotation, a factor analysis was conducted to identify the latent

    dimensions of organizational commitment. As Table 2 shows, it produced two distinctive

    organizational commitment factors, i.e. affective and continuance commitment that were

    loaded with four items on each factor.

    To test Hypothesis 2, we investigated the impact of the perception gap between local

    Mexican employees and Korean expatriates regarding compensation on affective and

    continuance commitment. For this purpose, we took the absolute value of the mean

    difference between the two groups of respondents in compensation, and calculated the

    t-value of each item on the two organizational commitment constructs. The results

    demonstrated that compensation gap was significantly related to affective commitment

    only (see Table 3). That is, the wider the perception gap about compensation between

    Mexican employees and Korean expatriates, the lower the affective commitment

    of Mexican workers. However, the perceived compensation gap was not significantly

    related with continuance commitment. Our results only support Hypothesis 2a.

    Hypothesis 3a proposed that there is a positive relationship between organizationalcommitment and job satisfaction. To test Hypothesis 3a, we analysed the

    relationship between affective as well as continuance commitment and job satisfaction

    using organizational tenure and education level as control variables. The literature on

    organizational commitment suggests that both education and tenure are important

    antecedents of commitment and need to be controlled (Cullen et al., 2002; Mathieu and

    Zajac, 1990). According to results in Table 4, only affective commitment was positively

    related to job satisfaction. Continuance commitment was not significantly related to job

    satisfaction.Finally, we tested Hypothesis 3b that organizational commitment is positively related

    to job performance. As demonstrated in Table 5, affective commitment was found to

    have a significantly positive correlation with job performance while continuance

    commitment had a significantly negative association with job performance. These

    findings are consistent with arguments by Meyer and Allen (1991).

    Discussion

    Using Korean companies as a sample, the present study represents a pioneering research

    that investigates the relationship between perceived compensation gap, organizational

    commitment, job satisfaction and job performance in managing MNCs overseas

    operations. Our results are consistent with past research and suggest that HCW perceive

    significant gaps in their compensation relative to expatriates (Chenet al., 2002). Yet, our

    results should be viewed as more robust as the perceived gaps were detected despite the

    fact that the social referent was not identified to the respondents.

    However, of greater interest to multinationals are our findings that such compensation

    gaps are inversely related to affective commitment. This research thus helps us

    understand the critical factors that influence HCW affective commitment. As expected,

    our findings suggest that compensation gaps were negatively related to one form of

    organizational commitment affective commitment. Such findings are consistent with

    past empirical research (Chen et al., 2002; Toh and Denisi, 2003) and the premises of

    equity theory (Adams, 1963). Relative to other reward components, compensation gaps

    tend to be more salient for HCW as they compare themselves with expatriates. This is not

    surprising because compensation tends to be a major focus of comparison for most

    people (Kulik and Ambrose, 1992). As such, in an effort to reduce the inequity perceived

    with respect to South Korean expatriates, the HCW tend to be less attached to the

    organization. Our findings suggest that MNCs should be careful in managing

    compensation gaps between HCW and expatriates, as they are very discernable and

    obvious to the HCW.

    We were nevertheless surprised to find that there was no relationship between the

    compensation gap and continuance commitment. Perhaps, consistent with most

    maquiladoras, the HCW have few other options with regards to work. As such, although

    they perceive a significant compensation gap, they may not be able to find other job

    alternatives and thus see no recourse but to stay with their current employer. Such

    reasoning potentially explains our inability to find a relationship between the

    compensation gap and continuance commitment. In fact, these results are consistent

    with the continued decline in turnover rate in the maquiladora industry. Compared to the

    growing stage of the maquiladora industry in the 1970s and 1980s, almost full

    implementation of NAFTA provisions has decreased the merits of establishing the

    maquiladoras and the labour market in the maquiladora industry has been stabilized

    (Sargent and Matthews, 2003). However, given the difficulty of explaining non-

    significant results, we note the speculative nature of our explanation hoping that future

    research can address this issue in more depth.

    Consistent with previous research, results also show that only affective commitment is

    positively related to job satisfaction (Cullenet al., 2002; Mathieu and Zajac, 1990) and job

    performance (Riketta,2002).In contrast to past research, however, our findingsindicate that

    continuance commitment is not related to job satisfaction and that it has a negative

    relationship to job performance.Albeitsurprising at first glance, suchfindings areconsistent

    with the conceptualizations of affective and continuance commitment. While affective

    commitment pertains to the emotional attachment and identification with the organization

    (Allen and Meyer, 1990), continuance commitment reflects employees sunk costs and

    investments (e.g. benefits) that prevent them from leaving the organization. Thus, whileaffective commitment implies that employees want to stay with the organization,

    continuance commitment suggests that they stay with the organization because they dont

    havemany optionselsewhere (Lemons andJones,2001). It is,therefore, notsurprising to see

    a more positive effect of affective commitment on job satisfaction and performance

    compared to continuance commitment,when considering managers preference of affective

    commitment over continuance commitment (Shoreet al., 1995).

    Our findings provide some useful guidance for Korean companies in enhancing the

    organizational commitment of local employees by identifying the areas that need

    improvement in their reward schemes offered to the Mexican workforce. Most

    importantly, Korean companies need to meet the expectations of Mexican employees

    about their compensation and to adjust the compensation level accordingly to increase

    the affective commitment of Mexican employees. Furthemore, with regard to our control

    variables, Mexican workers also perceived inequity in terms of their career development

    such as promotability and technical skills acquisition. Previous research (Paik andTeagarden, 1995) found that Korean companies in Mexico were not spending enough

    money to provide Mexican managers with necessary training, including general

    management and specialty courses. Mexican workers want Korean companies to support

    their individual careers by providing various training and development programmes.

    Korean MNCs should improve these reward schemes to encourage Mexican workers to

    feel that they are valued by the company.

    The contributions of this paper may not be limited only to Korean companies in

    a Mexican context, but are applicable to all MNCs operating outside their home country.

    The research results suggest that expatriates should know how to motivate the host country

    workforce and how to provide appropriate rewards by possessing significant cultural

    knowledge of their assigned host country. This will in turn increase the organizational

    commitment of the host country workforce, resulting in improved job performance.

    Several managerial implications can be drawn from this research. First, the research

    findings suggest that Mexican workers are clearly aware of the compensation and other

    rewards discrepancy between themselves and expatriate managers. To reduce any

    resentment from HCW, if possible, MNCs would be better off refraining from using

    expatriates in managing foreign subsidiaries. Instead, it would make more sense to hire

    local managers whose compensation is not significantly different from other local HCW.

    Local managers would also be more familiar with work-related values, thereby better

    positioned to offer proper rewards and thus generate higher levels of affective

    commitment on the part of the host country employees.

    Second, when using expatriates is inevitable, MNCs should carefully select those who

    possess appropriate cultural knowledge about the host country. Paik and Sohn (2004)

    contend that expatriates can be an effective means of control only if they have significant

    cultural knowledge of the host country. If expatriates have a clear understanding of HCW

    expectations, they can provide appropriate rewards including compensation that exactly

    fulfils those needs. Then the HCW may feel obligated to reciprocate and may become

    more committed to the organization. They will carry out the job assigned by the

    expatriate to a degree consistent with the perceived equity in the exchange. When

    managers and employees have a mutual agreement on what is considered to be most

    important in motivating workers, organizational commitment as well as job satisfaction

    and performance is expected to increase.

    Third, the research findings also have useful implications for training expatriate

    managers more effectively. With an almost exclusive focus in the international

    management literature upon the preparation and training of expatriates for international

    assignment success, there has been a major neglect of attention to HCWs inputcontributing to the optimization of foreign subsidiary performance (Vance and Paik,

    2002). Such neglect hampers the effective management of foreign subsidiaries since

    expatriates are ignorant of appropriate reward schemes of HCW that will motivate them

    to work to their maximum potential. To increase expatriate pre-departure training content

    validity, the HCW can make valuable contributions in designing appropriate rewards

    systems for their own benefit as well as for MNCs. Therefore, an expatriates

    pre-departure training programme should include knowledge of the proper reward

    schemes to be emphasized for the specific host country to enhance organizational

    commitment and work performance for a given HCW.

    Despite the intriguing findings, this paper does suffer from several limitations. First, the

    study was done with Mexican HCW and Korean expatriates and may not necessarily be

    readily applicable to all nationalities. We nevertheless hope that future research will

    replicateour study in wider populations. Furthermore, ourstudy ignoredcultural aspects and

    we hope that future studies will consider how national culture may influence perceptionsregarding compensation and organizational commitment. For example, it is plausible that

    workers in high power distance cultures such as Mexico are more likely to perceive

    compensation gap than those in low power distance cultures. Second, we measured the

    perceived gaps based on only one item, thereby raising reliability issues. Although we

    followed similar procedures to previously published research using only one item (Chen

    etal., 2002),we hopethat futureresearch will usemore sophisticatedmultiple instruments to

    measure compensation and other types of reward schemes. Finally, we also note that the

    Mexican workers were asked to rate their compensation in absolute terms ratherthan relative

    to the Korean expatriates. However, we reasoned that compensation gaps would be obvious

    if the Mexican workers were asked to rate their compensation relative to the South Korean

    expatriates. We areconfidentthat thecurrent results aremore robust as we still found that the

    compensation gap was related to organizational commitment.
