Research summary : We argue that a pure capabilities‐based view does not accurately explain the competitive dynamics of increasingly common settings in which firms act as both complementors and competitors. We propose that the Awareness‐Motivation‐Capability framework is more appropriate for these settings. We derive predictions from both a pure capabilities view and the AMC framework, and test those predictions in the U.S. auto leasing market, in which the leasing subsidiaries of car manufacturers directly compete with the same independent lessors who provide complements to the manufacturers. Although our results are consistent with capabilities playing an important role, motivation appears to be a critical factor explaining the competitive dynamics of the market. Managerial summary : Firms that compete with business units owned by larger corporate parents face additional considerations. Such subsidiary competitors can be motivated by broader corporate considerations, shifting their objectives, and consequently, their strategic actions. Expecting subsidiary competitors to pursue business unit profitability can mislead managers toward pricing, product mix, or market entry errors. We present an important example from consumer finance, where independent auto lessors, such as Bank of America (BoA), compete with captive leasing subsidiaries like Ford Motor Credit (FMC). Since FMC is motivated to subsidize and support vehicle sales for its manufacturer parent, a cost advantage is not enough for BoA to dominate the market. Understanding broader corporate motivations of competitors helps managers anticipate competition levels in potential markets, thereby improving decision‐making and performance.

This paper applies a consistent framework to four comparably sized metropolitan areas to identify and characterize their employment centers. Employment centers are identified as places that exceed a threshold employment density and a threshold employment level. They are also characterized as specializing on the basis of location quotient analysis. We find clear evidence of specialization in every employment center in the four metropolitan areas studied. Our interpretation is that what we are observing is a systematic change in metropolitan structure rather than a random sprawling of firms. We also find some evidence that the size distribution of employment centers follows the rank-size rule. This suggests that there is structure not only in the distribution of economic activity among the employment centers but also in their size distribution. Because less than 50 percent of metropolitan employment is within employment centers, future research should focus on understanding the more diffuse employment patterns. The rank-size rule gives some guidance as to the expected size distribution of employment throughout the metropolitan area.  相似文献

This paper explores the relationship between relevant senate committee membership and campaign contributions from financial services industry political action committees (PACs) from 1998 to 2002. Since this was a period of significant legislative activity affecting the industry, it provides a fruitful time period to investigate the relationship between contributions and committee membership. It is found that membership on the Senate Banking Committee is consistently related to contributions from financial services PACs. Membership on the Senate Finance Committee is related to PAC contributions from some sectors of the industry for some time periods. It is also found that contributions are significantly higher for those senators facing re-election in the particular election cycle. The importance of relevant committee membershipto PAC contributions in the senate is consistent with previous work dealing with the House.  相似文献

This paper takes as its starting point the assertion that current rangeland management in the central Eastern Cape Province (former Ciskei) of South Africa, is characterised primarily by an ‘open-access’ approach. Empirical material drawn from three case-study communities in the region is used to examine the main barriers to management of rangeland as a ‘commons’. The general inability to define and enforce rights to particular grazing resources in the face of competing claims from ‘outsiders’, as well as inadequate local institutions responsible for rangeland management are highlighted as being of key importance. These are often exacerbated by lack of available grazing land, diffuse user groups and local political and ethnic divisions. Many of these problems have a strong legacy in historical apartheid policies such as forced resettlement and betterment planning.  相似文献

This study examines the selectivity and timing performance of 218 UK investment trusts over the period July 1981 to June 2009. We estimate the Treynor and Mazuy (1966) and Henriksson and Merton (1981) models augmented with the size, value, and momentum factors, either under the OLS method adjusted with the Newey–West procedure or under the GARCH(1,1)-in-mean method following the specification of Glosten et al. (1993; hereafter GJR-GARCH-M). We find that the OLS method provides little evidence in favour of the selectivity and timing ability, consistent with previous studies. Interestingly, the GJR-GARCH-M method reverses this result, showing some relatively strong evidence on favourable selectivity ability, particularly for international funds, as well as favourable timing ability, particularly for domestic funds. We conclude that the GJR-GARCH-M method performs better in evaluating fund performance compared with the OLS method and the non-parametric approach, as it essentially accounts for the time-varying characteristics of factor loadings and hence obtains more reliable results, in particular, when the high frequency data, such as the daily returns, are used in the analysis. Our results are robust to various in-sample and out-of-sample tests and have valuable implications for practitioners in making their asset allocation decisions across different fund styles.  相似文献

We provide empirical evidence on the conjecture that in economic crises, firms could be forced to sell at deep discounts, or fire sale prices. Using the conventional stock price near the announcement date, we find instead distressed firms in crisis periods receive a 30% higher offer premium than distressed firms in normal periods; they also receive a 34% higher premium than non-distressed firms in crisis periods. Acquirers also do not gain, at announcement and over the long-term. Acquirers, however, may perceive they realize fire sale discounts if the reference is the targets’ highest price in the previous 52 weeks.  相似文献

Based on social-cognitive theory, this article proposes a model that seeks to explain why high status organizational members engage in unethical behavior. We argue that status differentiation in organizations creates social isolation which initiates activation of high status group identity and a deactivation of moral identity. We further argue that high status group identity results in insensitivity to the needs of out-group members which, in turn, results in lessened motivation to self-regulate ethical decision making. As a result of this identity activation, we demonstrate how high status individuals will be more vulnerable to engaging in unethical activities. Individual-level moderators of the relationships are also discussed.  相似文献
