Over the last decade and a half, there have been a number of studies investigating the phenomena of opportunism and relationship continuance (e.g., Heide and John, 1992; Noordewier et al., 1990), but the vast majority of them view the issue from the perspective of the firms, the buyer-supplier dyad dyad /dy·ad/ (di´ad) a double chromosome resulting from the halving of a tetrad.

LITERATURE REVIEW AND HYPOTHESES

Relational Norms and Dependence

Relational norms may be described as the values shared among exchange partners regarding what is deemed appropriate behavior in a relationship (e.g., Heide and John, 1992).. When buyer-supplier relationships are characterized char·ac·ter·ize

 by high relational norms, exchange parties are more committed (Gundlach et al., 1995) and exhibit a long-term orientation (Ganesan, 1994), thus lowering future negotiation costs (Artz and Norman, 2002). Over the last two decades, closer supply chain relationships exhibited by high relational norms such as trust, collaboration, long-term relationship, and increased information-sharing have evolved in many industries to help firms respond to changes (Droge and Germain, 2000; Hoetker et al., 2007; Monczka et al., 1998; Sengun and Wasti, 2007; Whipple and Frankel, 2000). Relationships with low relational norms are characterized by distributive dis·trib·u·tive

 (Walton and McKersie, 1965) or aggressive (Ganesan, 1993) bargaining behaviors. The use of legal contracts governs these relationships, and aggressive bargaining tactics are used to resolve disagreements. In short, high relational norm relationships may be characterized as partnerial or cooperative, while low relational norm relationships tend to be "arm's length" or competitive.

In the socio-economic literature, Hirschman (1970) and Helper and Sako (1995) use a continuum of firm relationship styles to explain differences between adversarial ad·ver·sar·i·al

Dependence can be termed as the cost of replaceability (e.g., Heide and John, 1988). A buyer that expects substantial switching and termination costs in their relationship with a supplier is said to be dependent on that supplier and, in many industries, buyer firms are becoming increasingly more dependent on their suppliers (Lyons et at, 1990), as outsourcing (1) Contracting with outside consultants, software houses or service bureaus to perform systems analysis, programming and datacenter operations.

See netsourcing, ASP, SSP and facilities management.  has increasingly become an industry-wide management practice (Espino-Rodriguez and Padron-Robaina, 2006; Narasimhan and Das, 1999). The absence of easily available competing suppliers in the external environment (Pfeffer and Salancik, 1978) and the existence of relationship-specific asset investments (Williamson, 1985) were therefore included in this study as key determinants of buyer dependence on their supplier. Buyers who are dependent on their supplier are expected to comply more readily with supplier requests. Social exchange theory (Thibaut and Kelley, 1959) teaches that parties choose to become dependent on their partners when the perception exists that the benefits resulting from asset investments outweigh out·weigh  
tr.v. out·weighed, out·weigh·ing, out·weighs
1. To weigh more than.

2. To be more significant than; exceed in value or importance: The benefits outweigh the risks.
 the costs of vulnerability, or opportunism. The benefits from these investments are often realized in the long run while the costs are incurred in the near-term. To decrease risks associated with dependence, some buyers include contract provisions to ensure the timely supply of materials and parts even when the relationship with a supplier defaults (Lyons et al., 1990).

Whereas dependence makes relational continuity a valued outcome, relational norms facilitate the achievement of this outcome (Joshi and Arnold, 1998) and the level of relational norms existing in a buyer-supplier relationship tends to moderate the effect of dependence on opportunism (Joshi and Arnold, 1997). Due to their potential impacts on opportunism and relationship continuance, relational norms and dependence (firm-level factors) are control variables in this study, allowing us to investigate their impacts in relation to those of assertiveness and cooperativeness (agent-level factors).

Opportunism

 impossible for a buyer to distinguish whether a supplier may behave opportunistically until a contract is in place since suppliers will most likely behave as if they are non-opportunistic during the pre-contract stage of the relationship (Lonsdale, 2001). To effectively structure different governance modes in order to prevent opportunism in a buyer-supplier relationship continues to represent a critical challenge for any firm (Wuyts and Geyskens, 2005; Pilling and Zhang, 1992). In a traditional adversarial contract relationship, the tendency for opportunism is greater than in a longer-term, trust-based partnerial relationship. Transaction cost economics and the resource-based view The resource-based view (RBV) is an economic tool used to determine the strategic resources available to a firm. The fundamental principle of the RBV is that the basis for a competitive advantage of a firm lies primarily in the application of the bundle of valuable resources at the  of the firm both espouse that buyers and suppliers that have invested in relationship-specific investments and share specific assets--characteristics of a partnerial relationship--are less likely to act opportunistically (e.g., Williamson, 1985; Conner and Prahalad, 1996).

As explained earlier, high relational norm relationships are characterized by parties that are committed (Gundlach et al., 1995) and demonstrate a long-term orientation (Ganesan, 1994). As a result, the partners in the relationship are confident that their actions will not be opportunistically abused (Heide and John, 1992). By providing a generalized gen·er·al·ized

 safeguard against partner opportunism (Heide and John, 1992), relational norms make parties more willing to engage in actions that result in relationship continuity. Also, in the high relational norm relationship, the expectation is that it is appropriate for exchange partners to work in the best interest of the relationship and that it is inappropriate for them to make moves that secure only unilateral unilateral /uni·lat·er·al/ (-lat´er-al) affecting only one side.

 gains (Gundlach et al., 1995).

Relationship Continuance

Relationship continuance in the buyer-supplier dyad can be described as the intention of both firms to keep the relationship ongoing, in spite of the presence of stressors in the relationship. For example, if a buyer is not greatly dependent on a particular supplier to continue providing parts, the likelihood of continuing a working relationship with that supplier is less than the case when the buyer is desperately in need of the supplier's product or service. If the buying firm has legitimate alternatives in the supply base to do business with, but opts to keep doing business with its incumbent supplier, then the intention to continue the relationship is very likely.

Research has shown that expectation of continuance in buyer-supplier relationships is strong when there are shared values between the exchange partners regarding what constitutes appropriate behavior in the relationship (Morgan and Hunt, 1994). It has been argued that the presence of relational norms increases the expectancy A mere hope, based upon no direct provision, promise, or trust. An expectancy is the possibility of receiving a thing, rather than having a vested interest in it.

The term has been applied to situations where an individual hopes and expects to receive something, generally
 of relationship continuity (Joshi and Arnold, 1998). These norms can take on relevant dimensions such as flexibility, information exchange, and solidarity, to name a few (Heide and John, 1992). Under conditions of high relational norms, buying firms have a high expectation of relationship continuity, while under low relational norms, buying firms have a low expectation (Joshi and Arnold, 1998). Also, evidence has shown that in some buyer-supplier relationships, the effect of trust is a deterrent de·ter·rent

Assertiveness and Cooperativeness in Managerial Decision-making

Wilmot and Hocker (2001) base negotiation, or conflict management, strategies on a two-dimensional framework: assertiveness and cooperativeness. They base this framework on the five different negotiation strategies provided by Kilmann and Thomas (1975)--avoidance, accommodation, collaboration, competition, and compromise. According to according to

 Wilmot and Hocker (2001), assertiveness is required when there exists a tendency of concern for oneself and cooperativeness is required in the presence of concern for others. The greater the concern for self, the greater the individual's assertiveness tendency, whereas the greater the concern for others, the greater the individual's cooperativeness tendency. Using Kilmann and Thomas' (1975) negotiation strategies, a high level of assertiveness would be exhibited by an individual engaged in competition and collaboration strategies and a low level of assertiveness would be exhibited by an individual engaged in accommodation and avoidance strategies. Also, a high level of cooperativeness would be exhibited by an individual engaged in collaboration and accommodation strategies and a low level of cooperativeness would be exhibited by an individual engaged in competition and avoidance strategies.

In our experiment, four of the five negotiation strategies, except for the compromise strategy, are collapsed into the two categories of assertiveness and cooperativeness. We did not include the compromise strategy in the formulation formulation /for·mu·la·tion/ (for?mu-la´shun) the act or product of formulating.

The tendencies of an individual's assertiveness and cooperativeness can be estimated by the following formula proposed by Volkema and Bergmann (1995).

Assertiveness = (competition + collaboration) - (avoidance + accommodation)

Cooperativeness = (collaboration + accommodation) - (competition + avoidance)

Hypotheses

As explained above, much of the existing buyer-supplier literature explores the phenomena of opportunism and relationship continuance from the perspective of the firm (Heide and John, 1992; Morgan and Hunt, 1994; Noordewier et al., 1990). It is our premise that with such far-reaching consequences that affect the viability of any existing buyer-supplier arrangement, the role of the agents involved with making such decisions cannot be ignored since managers working within the buyer and supplier firms often act as decision-making agents with regards to a number of supply chain functions--purchasing, parts procurement The fancy word for "purchasing." The procurement department within an organization manages all the major purchases. , contract negotiations, etc. The effects of these agents' negotiation characteristics (e.g., assertiveness and cooperativeness) need to be considered since they may influence supply chain decisions.

On the other hand, those with high degrees of cooperativeness who are concerned for others and focus more on mutual benefits of both parties are less likely to engage in opportunistic behaviors in the firm relationship. In other words Adv. 1. in other words - otherwise stated; "in other words, we are broke"

, agents' characteristics of assertiveness and cooperativeness can still influence opportunism, despite the dependence and relational norms in buyer-supplier relationships. This argument leads to the following hypotheses.

Hypothesis 1: The assertiveness of the decision-making agent has a positive effect on opportunism in the buyer-supplier relationship when controlling for dependence and relational norms in the buyer-supplier relationship.

Hypothesis 2: The cooperativeness of the decision-making agent has a negative effect on opportunism in the buyer-supplier relationship when controlling for dependence and relational norms in the buyer-supplier relationship.

However, when it comes to the critical decision of relationship continuance--whether the firm should continue the exchange relationship with the current supplier--the agent may rationally make the decision based on the degree to which the firm depends on the supplier and the strength of the relational ties between the two parties. The relationship cannot continue if either firm is unwilling to support the relationship, and the willingness to even do so can be contingent upon Adj. 1. contingent upon - determined by conditions or circumstances that follow; "arms sales contingent on the approval of congress"

 the strength of the existing relationship as well as the degree of dependence of one firm on the other. Also, for a buyer-supplier relationship to even come into existence, firm-level policies and procedures Policies and Procedures are a set of documents that describe an organization's policies for operation and the procedures necessary to fulfill the policies. They are often initiated because of some external requirement, such as environmental compliance or other governmental  need to be put in place to act as mechanisms supporting the relationship. Opportunism, on the other hand, can take place when an individual agent decides to act selfishly for profit or gain. Thus, opportunistic behaviors can be more directly influenced at the individual agent level by an agent's personality characteristics as opposed to relationship continuation decisions that may be primarily influenced by firm-level criteria. Based on this notion, we therefore contend that dependence and relational norms supersede To obliterate, replace, make void, or useless.

 the agents' behavioral characteristics of assertiveness and cooperativeness in affecting the relationship continuance decision. This reasoning suggests the following hypotheses.

Hypothesis 3: The Assertiveness of the decisionmaking agent has no significant effect on relationship continuance when controlling for dependence and relational norms in the buyer-supplier relationship.

Hypothesis 4: The Cooperativeness of the decisionmaking agent has no significant effect on relationship continuance when controlling far dependence and relational norms in the buyer-supplier relationship.

RESEARCH METHODOLOGY

Subjects and Experimental Design

To test our proposed hypotheses, we conducted a scenario-based experiment, which is commonly used in management research (e.g., Florey and Harrison, 2000; Stecher and Rosse, 2005). The subjects in our experiments were originally 300 students, but five did not complete the survey and were excluded from the study. The final sample was 295 students (55% male and 45% female; 78% Caucasian students and 22% non-Caucasian students), 61% and 39% of which were from a Midwestern university The P.A. Program is a 2-year program that starts in the summer. The D.O.,Pharm D., and Psy.D are 4-year programs. The D.O. degree is the legal and professional equivalent of the M.D.  in an urban setting and a rural Mid-Atlantic university in the U.S., respectively. In addition, 46% of the students had at least five years of work experience (either part-time or full-time). The sample characteristics are summarized in Table 1.

The manipulation checks were successfully performed and two-tailed t-tests indicated that (1) the average rating on the manipulation check item ("I personally feel that my company is highly dependent on the supplier") of subjects in High Dependence groups (mean = 5.69; 1 = Strongly Disagree, 7 = Strongly Agree) was statistically different from that of participants in the Low Dependence groups (mean = 3.64) at p < .001 level and (2) the average rating on the manipulation check item ("I personally feel that my company has an informal, close, cooperative relationship with the supplier") of subjects in High Relational Norms groups (mean = 5.64) was statistically different from that of participations in Low Relational Norms groups (mean = 3.08) at p < .001 level.

Measurement

Dependent Variables. Our dependent variables were Opportunism and Relationship Continuance. We used Joshi and Arnold's (1998) validated three-item opportunism scale and three-item intention-to-continue scale to measure opportunism and relationship continuance, respectively (see Appendix B). Subjects responded to each questionnaire item using a 1-7 scale (i.e., 1 = Strongly Disagree and 7 = Strongly Agree). Principal Component Analysis (PCA) showed that the three items of opportunism were highly correlated cor·re·late

It was first named as alpha by Cronbach (1951), as he had intended to continue with further instruments.  of 0.74. Therefore, they were combined into a single component measure. Similarly, the three items of relationship continuance were highly correlated and loaded onto a single component with an extracted variance of 80.15% and a Cronbach's alpha of 0.87. This was later used as a single component measure of relationship continuance in this study.

Independent Variables. Our independent variables were Assertiveness and Cooperativeness. We used the 16-item conflict management instrument modified from the Thomas-Kilmann Conflict Mode Instrument (Kilmann and Thomas, 1977). The original Thomas-Kilmann instrument was not suitable for the current study due to its length and the time limitations in our experiment. Consistent with the Thomas-Kilmann instrument, the 16 items were organized into four groups (with four items per group; see Appendix C), reflecting four related concepts--avoidance, accommodation, collaboration, and competition--which collectively determine the degrees of assertiveness and cooperativeness of individuals. After subjects responded to each questionnaire item using a 1-7 rating system, we computed the summed scores of avoidance, accommodation, collaboration, and competition based on their responses to the items in those four groups. Based on Volkema and Bergmann's (1995) formula (see above Literature Review), we then computed the scores of assertiveness and cooperativeness.

Control Variables. Our control variables were Dependence, Relational Norms, Subjects' Academic Major, Campus, Age, Ethnicity ethnicity Vox populi Racial status–ie, African American, Asian, Caucasian, Hispanic , Work Experience, and Gender. Since the main thrust of the study was to investigate the effects of agent-level factors (i.e., assertiveness and cooperativeness) on opportunism and relationship continuance in buyer-supplier relationship contexts, we controlled for dependence and relational norms, both of which were measured through experimental manipulations. High and low dependence conditions were coded as 1 and 0, respectively. Similarly, high and low relational norms conditions were coded as 1 and 0, respectively. We also controlled for other variables, including: (1) subjects' academic major: soft business majors--marketing and management--coded as 1 and hard (quantitative) business majors--finance, accounting and economics--coded as 0, (2) campus: 1 for urban campus and 0 for rural campus, (3) age divided into 6 ordinal (mathematics) ordinal - An isomorphism class of well-ordered sets.  groups below 20, 21-24, 25-29, 30-39, 40-49, and 50 years and above, coded as 1, 2, 3, 4, 5, and 6, respectively, (4) ethnicity, simply categorized cat·e·go·rize

Statistical Models

We used two separate regression models to test our hypotheses. The first model examines the effects of agents' Assertiveness and Cooperativeness on Opportunism after controlling for Dependence, Relational Norms and other control variables (Hypotheses 1 and 2). The second model investigates the effects of agents' Assertiveness and Cooperativeness on Relationship Continuance after controlling for Dependence and Relational Norms and other control variables (Hypotheses 3 and 4). The regression models are as follows.

Model 1: Opportunism = constant + [b.sub.1] Assertiveness + [b.sub.2] Cooperativeness + [b.sub.3] Dependence + [b.sub.4] Relational Norms + [b.sub.5] (Dependence x Relational Norms) + [b.sub.6] Soft Business Major + [b.sub.7] Campus + [b.sub.8] Age + [b.sub.9] Ethnicity + [b.sub.10] Managerial Experience + errors.

Model 2: Continuance = constant + [b.sub.1] Assertiveness + [b.sub.2] Cooperativeness + [b.sub.3] Dependence + [b.sub.4] Relational Norms + [b.sub.5] (Dependence x Relational Norms) + [b.sub.6] Soft Business Major + [b.sub.7] Campus + [b.sub.8] Age + [b.sub.9] Ethnicitv + [b.sub.10] Managerial Experience + errors.

DATA ANALYSIS AND RESULTS

We began the data analysis by performing correlation analyses. The correlations indicate that there are some significant associations among our control variables. Subjects' Age had a significant negative association with Soft Business Majors (e.g., management and marketing) (coeff. = -0.17, p < .01), and had a significant positive association with Campus (coeff. = 0.17, p < .01), with the majority of the older student subjects coming from the urban commuter campus. Ethnicity had a significant negative association with Campus (coeff. = -0.19, p < .001), implying greater non-Caucasian representation among the student subjects at the urban campus. Work Experience had a very strong significant positive association with Age (coeff. = 0.76, p < .001); older student subjects generally possessed greater work experience on their jobs. With regards to agent characteristics, Cooperativeness had a significant negative association with Assertiveness (coeff. = 0.14, p < .05), implying that among the respondents, those who reported a higher degree of cooperativeness tended also to report a lower degree of assertiveness. However, Variance Inflation Factors did not indicate multicollinearity problems among them.

Table 2 displays multiple regression results with Opportunism and Continuance as dependent variables. Model A1 tested the effects of agent-level factors: Assertiveness and Cooperativeness on Opportunism in the buyer-supplier relationship (Hypotheses 1 and 2). Results of the Full Model A1 in Table 2 indicate that after controlling for Dependence, Relational Norms, Major, Campus, Age, Ethnicity, Work Experience, and Gender, agent Cooperativeness was negatively associated with Opportunism in the buyer-supplier relationship (p < .001), whereas agent Assertiveness was not significantly related to Opportunism. These results yield support for Hypothesis 2 but not Hypothesis 1. The incremental R" for Model A1 was also significant (p < .01), whereby agent-level factors, Assertiveness and Cooperativeness, improved the total explained variation in Opportunism by 75% (8% [R.sup.2] in Control Model A1 versus 14% [R.sup.2] in Full Model A1). This provides support for our overall argument that agent-level factors, Cooperativeness and Assertiveness, matter in buyer supplier relationships even after taking organization-level factors, Dependence and Relational Norms, into consideration. In addition, we found that Ethnicity had a significant negative relationship with Opportunism (p < .05).

Model A2 was used to test the effects of Assertiveness and Cooperativeness (agent-level factors) on Relationship Continuance (Hypotheses 3 and 4). Results of Full Model A2 in Table 2 indicate that both agent Assertiveness and Cooperativeness were not significantly related to Relationship Continuance, whereas Dependence and Relational Norms were positively related to Relationship Continuance (p < .001). These results provide support for Hypotheses 3 and 4. We also found that Gender had a positively significant relationship with Relationship Continuance (p < .05).

Since the results in Table 2 showed that agent-level factors, Cooperativeness and Assertiveness, could significantly increase the explained variance Explained variance is part of the variance of any residual that can be attributed to a specific condition (cause). The other part of variance is unexplained variance. The higher the explained variance relative to the total variance, the stronger the statistical measure used.  in Opportunism, we performed four additional regression analyses to explore whether the effects of such agent-level factors on opportunism vary across four different Dependence-Relational Norms conditions: (1) Low Dependence--Low Relational Norms, (2) High Dependence --High Relational Norms, (3) Low Dependence--High Relational Norms, and (4) High Dependence--Low Relational Norms, using regression Models 1B, 2B, 3B and 4B in Table 3, respectively. The sample was divided into four sub-samples according to the Dependence-Relational Norms conditions. Then, the data from four sub-samples were analyzed an·a·lyze

, based on those four regression models.

We found that in Model B1 (Low Dependence--Low Relational Norms), agent Cooperativeness was negatively related to Opportunism with p < .001, whereas agent Assertiveness was not significantly related to Opportunism. This implies that the greater the cooperativeness of the agents, the less likely opportunism would occur in this circumstance Circumstance or circumstances can refer to:
  • Legal terms:
  • Aggravating circumstances
  • Attendant circumstance
. In Model B2 (High Dependence--High Relational Norms), agent Assertiveness and Cooperativeness were not significantly associated with Opportunism. This indicates that in this particular context, factors other than the agent's negotiation characteristics may play a part in influencing opportunistic behaviors. Interestingly, in Model B3 (Low Dependence--High Relational Norms), agent Assertiveness was positively related to Opportunism with p < .10, while agent Cooperativeness was not significantly related to Opportunism, implying that in a strong voice buyer-supplier partnership with low dependence, any show of opportunism could be partially explained by the assertiveness of the decision-making agent. Finally, in Model B4 (High Dependence-Low Relational Norms), agent Cooperativeness had a significant negative relationship with Opportunism (p < .01), while agent Assertiveness did not. This could indicate that the less cooperative the decision-making agent, the greater the chance of opportunistic behaviors in this context. In sum, the results of this exploratory study indicate that the effects of agent Cooperativeness and Assertiveness on Opportunism appeared to differ in different Dependence-Relational Norms conditions.

DISCUSSION

General Implications

The Role of Agents in Opportunism.

The current results show that agent level factors do matter in buyer-supplier relationships. Specifically, co-operativeness of the agents can restrain opportunism in exchange relationships. While the extant literature Extant literature refers to texts that have survived from the past to the present time. Extant literature can be divided into extant original manuscripts, copies of original manuscripts, quotations and paraphrases of passages of non-extant texts contained in other works,  suggests that developing relational norms and managing dependency are critical to successful buyer-supplier relationships (Heide and John, 1992; Morgan and Hunt, 1994), this study also shows that choosing agents who are cooperative in nature and self-governed from opportunism cannot be ignored since opportunism can undermine the long-term viability of the relationships. By filling the void of agent-level factors in previous research, this study makes a modest contribution to the buyer-supplier relationship literature.

Cooperativeness-Relational Norms Interaction Effects on Opportunism. Exploratory results of our study seem to suggest interaction effects between Relational Norms and agent Cooperativeness on Opportunism. As seen in Table 3, agent Cooperativeness has a significantly strong influence on Opportunism in the Low Relational Norms cases (Models B1 and B4), but not in the High Relational Norms cases (Models B2 and B3). This implies that when relational norms are lacking between constituents in a supply chain (i.e., Low Relational Norms scenarios), the greater the influence the cooperativeness of the decision-making agent plays in restraining RESTRAINING.

 agent behaviors. The agents with strong predispositions toward opportunism may be reluctant to act opportunistically. Similarly, agents who are indeed cooperative in nature may feel compelled to act according to the norms rather than their own conscience. Therefore, the personal cooperativeness of the agents may not exert influence in the strong relational norms cases. In short, our research provides only preliminary evidence that agent-level cooperativeness and firm-level relational norms could potentially interact with each other in influencing opportunism. However, further a priori a priori

 of Those Who Trust You. Other exploratory insights can be found when we observe Model B3 in Table 3, the Low Dependence--High Relational Norms case. Here, the buying firm has little dependence on the supplier, yet has a well-established business relationship with the supplier. This provides a recipe for buyer opportunism to occur. This is analogous to the notion that it is always easier to succeed in betraying or deceiving those who already trust you.

 and knows that the supplier respects the established relationship and is likely to accommodate requests from the buyer, then he or she may take advantage of this situation. We see in Table 3 that Assertiveness is significantly related to Opportunism in the Low Dependence--High Relational Norms case. The agent shows some significant Opportunism, but at the 0.10 level.

On the contrary, in the High Dependence cases (Models B2 and B4 in Table 3), it is possible that there is little room for the agent to act opportunistically. When the buyer is highly dependent upon its supplier, there is no incentive for buyer agents to act opportunistically since they depend on the supplier. Even when relational norms are low, the buyer may not know how the supplier will react because they are not familiar with one another. The supplier's response or retaliation RETALIATION.

For example, if a nation should lay a very heavy tariff on American goods, the United States would be justified in return in laying heavy duties on the manufactures and  to the opportunistic behaviors may thus be unpredictable and could adversely affect the buyer's business viability in such a high dependence context. Contrastingly, in the Low Dependence cases (Models B1 and B3 in Table 3), the buyer may act more opportunistically than in the High Dependence cases. In sum, when agents are highly assertive and when the buying firm's dependence upon the supplier is low, there is little check to opportunistic behaviors, even when the norms of the relationship are strongly established.

 will need to be performed to gain further insight.

Demographic Factors. Our findings in Table 2 also suggest that some demographic variables may impact the dynamics in buyer-supplier relationships. Specifically, we found that Ethnicity was significantly related to Opportunism while Gender was significantly related to Relationship Continuance. This may imply that idiosyncratic id·i·o·syn·cra·sy

2. A physiological or temperamental peculiarity.

3.
 differences in ethnic groups and gender diversity in part shape the likelihood of decision-making agents to act opportunistically and to maintain the existing exchange relationships, respectively. These findings are in line with a broader-spectrum of the gender and diversity literature, which suggests that certain behaviors (e.g., leadership, technology acceptance) differ with gender and ethnicity (e.g., Eagly and Johnson, 1990; Venkatesh and Morris, 2000).

Managerial Implications

The findings of this study suggest that agent-level factors play an important role in buyer-supplier relationships and have managerial implications pertaining to various phases in the relationship development process (e.g., Dwyer et al., 1987). First, in selecting exchange partners (buyers or suppliers) during the relationship awareness and exploration phases, firms should incorporate the characteristics of the agents who will represent the partner companies as part of their selection criteria. When a firm considers partnering with another firm in a supply chain, several criteria such as price, quality, proximity, and reputation may be used to aid in the choice (Reid and Sanders San´ders

n. 1. An old name of sandalwood, now applied only to the red sandalwood. See under Sandalwood.
, 2005; Swift and Gruben, 2000). However, many of these are firm-level considerations. Our results indicate that other criteria such as agent characteristics should also be considered. A firm looking for a supply chain partner should be wary in choosing a company that possesses only adequate organizational-level criteria but has an uncooperative or overly assertive agent representing their business. The agent should thus be considered in the selection decision.

A second implication is relevant to the relationship expansion and commitment phases. When firms conduct business in an existing buyer-supplier relationship, each firm should carefully monitor the personnel turnover of the agents in the partner company. In today's business landscape, personnel turnover either through corporate restructuring restructuring - The transformation from one representation form to another at the same relative abstraction level, while preserving the subject system's external behaviour (functionality and semantics).  or through voluntary career movement and attrition Attrition

 or is eliminated from his or her job, a new agent is put in place. A change in agent may change the degree of relational risk associated with potential opportunism. Therefore, agent turnover may signal the need for change in governance or safeguard mechanisms to help the partnering firm adapt to the business behaviors of the new agent or vice versa VICE VERSA. On the contrary; on opposite sides. .

That being said, we acknowledge that implementing the above recommendations lend themselves more easily to some industry scenarios than others. For example, many industries such as today's automotive, computer, and aerospace industries are experiencing massive supply base reductions to simplify the managing of multiple suppliers and to develop more closely-knit supply networks. This facilitates the creation of established working relationships between several purchasing and procurement agents in the supply base, making it easier for the buyer to consider agent-level characteristics in their supplier selection decisions. Also, certain firm policies and procedures can be created (such as a balanced scorecard Balanced Scorecard

Implementing protocols and rubrics for supplier selection criteria can also aid in the decision making, and the practice of monitoring agent turnover within key suppliers can be developed by buyer firms to facilitate proper evaluation of supplier companies and their agents.

Finally, in some cases, firms are moving toward the dissolution phase in which the buyer-supplier relationship is strained and about to be terminated for various reasons (i.e., opportunism, unsatisfactory performance, change in business demand, etc.). For firms in this circumstance, our results imply that if the viability of the relationship is undermined by opportunism and the relationship is on the verge On the Verge (or The Geography of Yearning) is a play written by Eric Overmyer. It makes extensive use of esoteric language and pop culture references from the late nineteenth century to 1955.  of termination, then one consideration may be to change the agent to actually revitalize re·vi·tal·ize

 and resurrect the relationship before the choice of termination is made. Replacing the uncooperative agent who may be acting opportunistically with a new cooperative agent may send the signal to the partnering firm that opportunism problems are recognized and that efforts are being made to solve the problem and to restore mutual trust.

Limitations and Future Research

The researchers acknowledge that this study is not without its limitations. First, the use of students from two geographic regions as surrogates for actual purchasing managers presents external validity External validity is a form of experimental validity.[1] An experiment is said to possess external validity if the experiment’s results hold across different experimental settings, procedures and participants.  limitations. Nevertheless, the extant student-manager surrogacy surrogacy See Gestational surrogacy.  literature does suggest that students appear to exhibit similar decision-making patterns to those of managers in multiple decision-making contexts such as marketing, production and operations, lobbying, and ethical dilemmas (e.g., Corfman and Lehmann, 1994; Potters and van Winden, 2000; Remus, 1986; Wyld and Jones, 1997). Since the decision making in this study was in the purchasing/ buyer-supplier relationship context, which is multifaceted and involves some aspects of marketing, operations and dilemmas regarding opportunism and relationship continuance, student subjects can be used as reasonable surrogates for practicing managers in this study. Future research can address the external validity limitation by replicating the experiment in this study, using manager subjects or subjects from broader geographic regions. Another limitation is that the results are based on a fictitious Based upon a fabrication or pretense.

 purchasing scenario. It is not a "real-world" situation involving real-time management decision-making. Although the scenario was validated by Joshi and Arnold (1998), it is still based on role play rather than actual business incidents. To improve realism, future research may empirically derive scenarios from real-world business cases. Finally, some demographic variables in the study (i.e., Ethnicity and Gender) had significant impact on certain aspects of buyer-supplier relationships such as opportunism and relationship continuance, although they were not part of our research question. These demographic variables may collectively improve our understanding of various buyer-supplier relationship phenomena and future research can examine the role of agents' demographics The attributes of people in a particular geographic area.

Although this study is not all-inclusive, it sheds light on the role of the agent in buyer-supplier relationships. As explained in the Literature Review above, much of the existing buyer-supplier literature views supply chain decision-making issues such as opportunism and relationship continuance from the perspective of the firm, with the role of the agent often overlooked. However, our study reveals that the characteristics of agents actually do play some part in the buyer-supplier relationship, at least in the case of opportunism. This implies that viewing supply chain decision problems from merely a firm perspective may be too limiting in some situations, particularly when opportunism is of major concern. Future research can further investigate the role of the agent and agent characteristics to provide more insights into their impacts on various aspects of buyer-supplier relationships.

Conclusion

Recently, the supplier informed you that they are involved in a labor
dispute. Consequently, they are temporarily unable to guarantee
schedule delivery. This creates some uncertainty for your organization.
Delayed delivery of microchips, may, for example, cause problems for
your organization in meeting delivery schedules to customers. The
supplier has called to get your regular order. Drawing from experience,
how would you be most likely to react in this situation? Please rate
each of these statements to the extent that they match with your
expectation of your reaction.
