In the literature, several motives for takeovers have been identified. One is the desire for synergy. That is, similarities or complementarities between the acquiring and target firms are expected to result in the combined value of the enterprises exceeding their worth as separate firms (Collis and Montgomery, 1998). A second motive involves the expectation that acquirers can extract value because target companies have been managed inefficiently (Varaiya, 1987).

A third motive is attributed to managerial hubris – the notion that senior executives, in overestimating their own abilities, acquire companies they believe could be managed more profitably under their control. Agency theory motive is the anticipation that firm expansion will positively impact the compensation of top managers since there tends to be a direct relation between firm size and executive pay.

Contemporary specialists contend that managerial ownership incentives may be expected to have divergent impacts on corporate strategy and firm value. This premise has been recognized in previous studies. For instance, Stulz (1988) has examined the ownership of managers of target companies and has proposed that the relationship between that ownership and the value of target firms may initially be positive and then subsequently become negative with rising insider ownership.

Moreover, Shivdasani (1993) empirically shows that the relationship of the ownership structure of target companies with the value of hostile bids is not uniformly positive. McConnell and Servaes (1990) have likewise analyzed the relationship of equity ownership among corporate insiders and Tobin’s q. Their results demonstrate a non-monotonic relation between Tobin’s q and insider equity stakes. Wright et al. (1996: 451) have shown a non-linear relationship between insider ownership and corporate strategy related to firm risk taking.

Ownership Incentives and Changes in Company Risk Motivating Acquisitions

An agency-theoretic motive for acquisitions has been used to explain managerial preferences for risk-reducing corporate strategies (Wright et al., 1996). The implication is that both principals and agents prefer acquiring target companies with higher rather than lower returns. In that, shareholders and managers have congruent interests.

The interests, however, diverge in terms of risk considerations associated with acquisitions.

Because shareholders possess diversified portfolios, they may only be concerned with systematic risk and be indifferent to the total variance of returns associated with a takeover. Senior managers may alternatively prefer risk-reducing corporate strategies, unless they are granted ownership incentives. That is because they can not diversify their human capital invested in the firm.

In the literature, it has been argued that agency costs may be reduced as managerial ownership incentives rise. The reason is that, as ownership incentives rise, the financial interests of insiders and shareholders will begin to converge. Analysts conjecture, however, that such incentives may not consistently provide senior executives the motivation to lessen the agency costs associated with an acquisition strategy. Inherent is the presumption that the nature of executive wealth portfolios will differently influence their attitudes toward corporate strategy. The personal wealth portfolios of top managers are comprised of their ownership of shares/options in the firm, the income produced from their employment, and assets unrelated to the firm.

Presumably, as senior executives increase their equity stakes in the enterprise, their personal wealth portfolios become correspondingly less diversified. Although stockholders can diversify their wealth portfolios, top executives have less flexibility if they own substantial shares in the firms they manage. Hence, if a significant portion of managers’ wealth is concentrated in one investment, then they may find it prudent to diversify their firms via risk-reducing acquisitions.

In the related literature, however, takeovers and risk taking have been approached differently from the described approach. Amihud and Lev (1999) have contended that insiders’ employment income is significantly related to the firm’s performance. Thus, managers are confronted with risks associated with their income if the maintenance of that income is dependent on achieving predetermined performance targets. Reasonably, in the event of either corporate underperformance or firm failure, CEOs not only may lose their current employment income but also may seriously suffer in the managerial labor market, since their future earnings potential with other enterprises may be lowered. Hence, the risk of executives’ employment income is impacted by the firm’s risk. The ramification of Amihud and Lev’s (1999) contentions is that top managers will tend to lower firm risk, and therefore their own employment risk, by acquiring companies that contribute to stabilizing of the firm’s income, even if shareholder wealth is adversely affected.

Consistent with the implications of Amihud and Lev’s arguments, Agrawal and Mandelker (1987) have similarly suggested that managers with negligible ownership stakes may adopt risk-reducing corporate strategies because such strategies may well serve their own personal interests. With ownership incentives, however, managers may be more likely to acquire risk-enhancing target companies, in line with the requirement of wealth maximization for shareholders. The notion that at negligible managerial ownership levels, detrimental risk-reducing acquisition strategies may be emphasized, but with increasing ownership incentive levels, beneficial risk-enhancing acquisitions may be more prevalent is also suggested in other works (Grossman and Hoskisson, 1998). The conclusion of these investigations is that the relationship between insider ownership and risk enhancing, worthy corporate acquisitions is linear and positive.

Some experts assert that CEOs’ personal wealth concentration will induce senior managers to undertake risk-reducing firm strategies. Portfolio theory’s expectation suggests that investors or owner-managers may desire to diversify their personal wealth portfolios. For instance, Markowitz (1952: 89) has asserted that investors may wish to “diversify across industries because firms in different industries. . . have lower covariances than firms within an industry.” Moreover, as argued by Sharpe (1964: 441), “diversification enables the investor to escape all but the risk resulting from swings in economic activity.” Consequently, managers with substantial equity investments in the firm may diversify the firm via risk-reducing acquisitions in order to diversify their own personal wealth portfolios. Because they may be especially concerned with risk-reducing acquisitions, however, their corporate strategies may not enhance firm value through takeovers, although managerial intention may be to boost corporate value.

The above discussion is compatible with complementary arguments that suggest that insiders may acquire non-value-maximizing target companies although their intentions may be to enhance returns to shareholders. For instance, according to the synergy view, while takeovers may be motivated by an ex-ante concern for increasing corporate value, many such acquisitions are not associated with an increase in firm value.

Alternatively, according to the hubris hypothesis, even though insiders may intend to acquire targets that they believe could be managed more profitably under their control, such acquisitions are not ordinarily related to higher profitability. If acquisitions which are undertaken primarily with insider expectations that they will financially benefit owners do not realize higher performance, then those acquisitions which are primarily motivated by a risk-reducing desire may likewise not be associated with beneficial outcomes for owners. Additionally, it can be argued that shareholders can more efficiently diversify their own portfolios, making it unnecessary for managers to diversify the firm in order to achieve portfolio diversification for shareholders.

Risk Associated with HRM practices in International Acquisitions

There are a number of reasons why the HRM policies and practices of multinational corporations (MNCs) and cross-border acquisitions are likely to be different from those found in domestic firms (Dowling, Schuler and Welch, 1993). For one, the difference in geographical spread means that acquisitions must normally engage in a number of HR activities that are not needed in domestic firms – such as providing relocation and orientation assistance to expatriates, administering international job rotation programmes, and dealing with international union activity.

Second, as Dowling (1988) points out, the personnel policies and practices of MNCs are likely to be more complex and diverse. For instance, complex salary and income taxation issues are likely to arise in acquisitions because their pay policies and practices have to be administered to many different groups of subsidiaries and employees, located in different countries. Managing this diversity may generate a number of co-ordination and communication problems that do not arise in domestic firms. In recognition of these difficulties, most large international companies retain the services of a major accounting firm to ensure there is no tax incentive or disincentive associated with a particular international assignment.

Finally, there are more stakeholders that influence the HRM policies and practices of international firms than those of domestic firms. The major stakeholders in private organizations are the shareholders and the employees. But one could also think of unions, consumer organizations and other pressure groups. These pressure groups also exist in domestic firms, but they often put more pressure on foreign than on local companies. This probably means that international companies need to be more risk averse and concerned with the social and political environment than domestic firms.

Acquisitions and HRM Practices: Evidence from Japan, the US, and Europe

In contemporary context, international human resource management faces important challenges, and this trend characterizes many Japanese, US and European acquisitions.  From the critical point of view, Japanese companies experience more problems associated with international human resource management than companies from the US and Europe (Shibuya, 2000). Lack of home-country personnel sufficient international manage­ment skills has been widely recognized in literature as the most difficult problem facing Japanese compa­nies and simultaneously one of the most significant of US and European acquisitions as well.

The statement implies that cultivating such skills is difficult and that they are relatively rare among businessmen in any country. Japanese companies may be particularly prone to this problem due to their heavy use of home-country nationals in overseas management positions. European and Japanese acquisitions also experience the lack of home country personnel who want to work abroad, while it is less of an impediment for the US companies.

In the US acquisitions expatriates often experience reentry difficulties (e.g., career disruption) when re­turning to the home country: This problem was the one most often cited by US firms.  Today Japanese corporations report the relatively lower incidence of expatriate reentry diffi­culties, and it is surprising given the vivid accounts of such problems at Japanese firms by White (1988) and Umezawa (1990). However, the more active role of the Japanese person­nel department in coordinating career paths, the tradition of semi­annual musical-chair-like personnel shuffles (jinji idoh), and the continu­ing efforts of Japanese stationed overseas to maintain close contact with headquarters might underlie the lower level of difficulties in this area for Japanese firms (Inohara, 2001).

In contrast, the decentralized structures of many US and European firms may serve to isolate expatriates from their home-country headquarters, making reentry more problematic. Also, recent downsiz­ing at US and European firms may reduce the number of appropriate management positions for expatriates to return to, or may sever expatri­ates’ relationships with colleagues and mentors at headquarters. Furthermore, within the context of the lifetime employment system, individ­ual Japanese employees have little to gain by voicing reentry concerns to personnel managers. In turn, personnel managers need not pay a great deal of attention to reentry problems because they will usually not result in a resignation. In western firms, reentry problems need to be taken more seriously by personnel managers because they frequently result in the loss of a valued employee.

A further possible explanation for the higher incidence of expatriate reentry problems in western multinationals is the greater tendency of those companies to implement a policy of transferring local nationals to headquarters or other international operations. Under such a policy, the definition of expatriate expands beyond home-country nationals to en­compass local nationals who transfer outside their home countries. It may even be that local nationals who return to a local operation after working at headquarters or other international operations may have their own special varieties of reentry problems.

Literature on international human resource practices in Japan, the US and Europe suggest that the major strategic difficulty for the MNCs is to attract high-caliber local nationals to work for the company. In general, acquisitions may face greater challenges in hiring high-caliber local employees than do domestic firms due to lack of name recognition and fewer relationships with educators or others who might recommend candidates.

However, researchers suggest that this issue is significantly more difficult for Japanese than for US and European multinationals. When asked to describe problems encoun­tered in establishing their US affiliates, 39.5% of the respondents to a Japan Society survey cited “finding qualified American managers to work in the affiliate” and 30.8% cited “hiring a qualified workforce” (Bob & SRI, 2001). Similarly, a survey of Japanese companies operating in the US conducted by a human resource consulting firm found that 35% felt recruiting personnel to be very difficult or extremely difficult, and 56% felt it to be difficult (The Wyatt Company, 1999). In addition to mentioned problem, Japanese acquisition encounter high local employee turnover, which is significantly more prob­lematic for them due to the near-total absence of turnover to which they are accustomed in Japan.

The US, European and Japanese companies admit very rarely that they encounter local legal challenges to their personnel policies. However, in regard to Japanese acquisitions large  amount of press coverage has been given to lawsuits against Japanese companies in the United States and a Japanese Ministry of Labor Survey in which 57% of the 331 respondents indicated that they were facing potential equal employ­ment opportunity-related lawsuits in the United States (Shibuya, 2000).


This research investigates whether corporate acquisitions with shared technological resources or participation in similar product markets realize superior economic returns in comparison with unrelated acquisitions. The rationale for superior economic performance in related acquisitions derives from the synergies that are expected through a combination of supplementary or complementary resources.

It is clear from the results of this research that acquired firms in related acquisitions have higher returns than acquired firms in unrelated acqui­sitions. This implies that the related acquired firm benefits more from the acquirer than the unrelated acquired firm. The higher returns for the related acquired firms suggest that the combination with the acquirer’s resources has higher value implications than the combination of two unrelated firms. This is supported by the higher total wealth gains which were observed in related acquisitions.

I did however, in the case of acquiring firms, find that the abnormal returns directly attributable to the acquisition transaction are not significant. There are reasons to believe that the announcement effects of the transaction on the returns to acquirers are less easily detected than for target firms. First, an acquisition by a firm affects only part of its businesses, while affecting all the assets (in control-oriented acqui­sitions) of the target firm. Thus the measurability of effects on acquirers is attenuated. Second, if an acquisition is one event in a series of implicit moves constituting a diversification program, its individual effect as a market signal would be mitigated.

It is also likely that the theoretical argument which postulates that related acquisitions create wealth for acquirers may be underspecified. Relatedness is often multifaceted, suggesting that the resources of the target firm may be of value to many firms, thus increasing the relative bargaining power of the target vis-a-vis the potential buyers. Even in the absence of explicit competition for the target (multiple bidding), the premiums paid for control are a substantial fraction of the total gains available from the transaction.

For managers, some implications from the research can be offered. First, it seems quite clear from the data that a firm seeking to be acquired will realize higher returns if it is sold to a related than an unrelated firm. This counsel is consistent with the view that the market recognizes synergistic combinations and values them accordingly.

Second, managers in acquiring firms may be advised to scrutinize carefully the expected gains in related and unrelated acquisitions. For managers the issue of concern is not whether or not a given kind of acquisition creates a significant total amount of wealth, but what percentage of that wealth they can expect to accrue to their firms. Thus, although acquisitions involving related technologies or product market yield higher total gains, pricing mechanisms in the market for corporate acquisitions reflect the gains primarily on the target company. Interpreting these results conservatively, one may offer the argument that expected gains for acquiring firms are competed away in the bidding process, with stockholders of target firms obtaining high proportions of the gains.

On a pragmatic level this research underscores the need to combine what may be called the theoretical with the practical. In the case of acquisitions, pragmatic issues like implicit and explicit competition for a target firm alter the theoretical expectations of gains from an acquisition transaction. Further efforts to clarify these issues theoretically and empirically will increase our understanding of these important phenomena.
