Two questions facing motor carrier managers are (1) whether carriers should specialize in providing full truckload (TL) or less‐than‐truckload (LTL) services vis‐à‐vis offering mix of both and (2) whether this decision is contingent on carrier size. Yet, the literature provides little guidance because research to date has offered contradictory theoretical predictions and inconsistent empirical findings. Drawing on the theory of strategic purity and information processing theory, we explain why service specialization is likely to increase carriers' technical efficiency and why size will have a more pronounced effect on technical efficiency for carriers specializing in LTL services versus TL services. To test our theory, we assemble a panel data set from archival government sources regarding general freight motor carriers' provision of LTL and TL services. We measure carriers' technical efficiency using data envelopment analysis and test our hypotheses by fitting a series of panel data mixed‐effects models. Our results indicate that carriers are most technically efficient when they specialize in one service type. We also find that size positively affects technical efficiency but only for carriers specializing in LTL services; no returns to scale with regard to technical efficiency exist for carriers specializing in TL services. 相似文献

This paper proposes a theory of competitive agglomeration—a new enquiry into the origins of hierarchical structures and governments.
As a motivating example we analyze the Viking age—the roughly 300 year period beginning in 800 AD—from the perspective of
the economics of conflict. The Viking age is interesting because throughout the time period, the scale of conflict increased—small
scale raiding behaviour eventually evolved into large scale clashes between armies. With this observation in mind, we present
a theoretical model describing the incentives both the defending population and the invading population had to agglomerate
into larger groups to better defend against attacks, and engage in attacks, respectively. We tentatively postulate that competitive
agglomeration during the Viking era was a key impetus to state formation in Europe. 相似文献

A firm that simultaneously engages in a high degree of both innovation and efficiency follows an approach that is often referred to as an ambidextrous strategy. Surprisingly, relatively few firms are able to balance these two emphases. Internal battles for resources often tip the scales in favor of efficiency over innovation, or vice versa. Management gurus frequently warn that simultaneously pursuing both can set the firm up for mediocre performance, yet the turbulent nature of today’s markets and cut-throat competition create a renewed need for firms to reconsider this dual approach for longer-term success. Unfortunately, practical insights from empirical studies regarding performance benefits and implementation issues are still scant. Perhaps this is one reason why few firms are successful in both efficiency and innovation. In this article, we provide evidence—using a cross-industry survey of senior marketing managers in publicly-traded U.S. firms—that firms which successfully employ an ambidextrous strategy outperform those which overemphasize either efficiency or innovation. Furthermore, we highlight marketing’s role as an example of the often overlooked need for successful functional implementation. Finally, we provide useful methods for managers to answer three key questions: (1) Is my firm ambidextrous?; (2) Should my firm be ambidextrous?; and, if so (3) How can my firm become ambidextrous? 相似文献

Does technologically-supported work connectivity help young managers and professionals under the age of 45 deal with the pressing demands of their work, or does the presence of work-connecting technologies exacerbate the tendencies of this talent force to engage in more work and longer working hours? Utilizing both surveys and follow-up focus group interactions, this study found that while work-connecting technologies permitted a greater range of options regarding when and where work was done, this same connectivity provided constant availability to work and often drove expectations that more must be done, thereby increasing the likelihood of longer work hours and—surprisingly—leading to a diminished sense of flexibility. Study participants offer insights regarding the thought processes behind these outcomes. Perspectives on how emerging leaders and their organizations can effectively manage and achieve the potential of enhanced connectivity are provided. A four-phased approach is recommended. First, we discuss key cultural dynamics. Second, the role of organizational expectations and practices is emphasized. Third, we consider a set of responsibilities for organizational leaders, whose actions and cues provide the most vivid clarity for young managers attempting to decide where to draw the work/life balance line. Finally, the challenge and responsibility of personal accountability is presented. Consideration of a work paradigm that reorients our thinking about traditional “face time,” and strives to bridge the gap between the potential and pervasive impact of work-connecting technologies, is also included. 相似文献

If your company operates in a developing country, AIDS is your business. While Africa has received the most attention, AIDS is also spreading swiftly in other parts of the world. Russia and Ukraine had the fastest-growing epidemics last year, and many experts believe China and India will suffer the next tidal wave of infection. Why should executives be concerned about AIDS? Because it is destroying the twin rationales of globalization strategy-cheap labor and fast-growing markets--in countries where people are heavily affected by the epidemic. Fortunately, investments in programs that prevent infection and provide treatment for employees who have HIV/AIDS are profitable for many businesses--that is, they lead to savings that outweigh the programs' costs. Due to the long latency period between HIV infection and the onset of AIDS symptoms, a company is not likely to see any of the costs of HIV/AIDS until five to ten years after an employee is infected. But executives can calculate the present value of epidemic-related costs by using the discount rate to weigh each cost according to its expected timing. That allows companies to think about expenses on HIV/AIDS prevention and treatment programs as investments rather than merely as costs. The authors found that the annual cost of AIDS to six corporations in South Africa and Botswana ranged from 0.4% to 5.9% of the wage bill. All six companies would have earned positive returns on their investments if they had provided employees with free treatment for HIV/AIDS in the form of highly active antiretroviral therapy (HAART), according to the mathematical model the authors used. The annual reduction in the AIDS "tax" would have been as much as 40.4%. The authors' conclusion? Fighting AIDS not only helps those infected; it also makes good business sense. 相似文献
