FIRST-MOVER ADVANTAGE: THE OPPORTUNITY CURVE 总被引:1,自引:0,他引:1
A model depicting first-mover dynamics is proposed wherein certain types of strategic barriers activated by the first-mover strategy figure prominently in preserving benefits in the time dimension. Strategic barriers conferring singularity (i.e. one-time benefit) are considered to be the most effective preservers of first-mover advantage. the theoretical model is tested empirically in a study of six major industries. Benefits operationalized as industry share and profit share were found to decline consistently with industry age according to an exponential function designated the opportunity curve. 相似文献

C S van der Waal 《Development Southern Africa》1994,11(3):429-436
In One destiny: Our common future in Africa the author relates, in popular fashion, a series of incidents which convinced him that the basic difference between black and white in South Africa is cultural deep‐seated and the cause of underdevelopment and conflict He develops a circular argument in which world‐view is taken as the root of perceptions, values and activities. The effects of experience and economic and political factors are given secondary importance. This argument cannot accommodate social change and differentiation, and the author tends to concentrate on perceptions and events which he finds morally unacceptable. He gives an unbalanced assessment and an ethnocentric interpretation of African life. Possible reasons for this type of argument are explored and an alternative which takes its departure from the interaction between experience and perception is offered 相似文献

Statement of Financial Accounting Standards (SFAS) No. 96, “Accounting for Income Taxes,” issued by the Financial Accounting Standards Board (FASB) in December 1987 changed accounting for income tax recognition and accrual. The original deadline for implementation of SFAS No. 96 was December 15, 1988, and earlier adoption was encouraged. This study examines empirically the stock price impact of four pertinent announcement dates regarding SFAS No. 96 for 19 banks that adopted the statement in late 1987 and early 1988. Our results suggest that these early bank adopters have different characteristics from other banks that cause them to benefit from the changes in accounting for deferred taxes and explain their voluntary adoption of the standard. 相似文献

I examine the aggregate expected profit generated by informed traders of diverse ability in a competitive market. I assume that efficient traders get perfect information on asset values whereas inefficient traders get noisy information. In the presence of order size restrictions, I show that the aggregate expected profit generated by efficient and inefficient traders together can be higher than that generated by efficient traders alone. Thus, inefficient traders can create value in a constrained trading environment. 相似文献

Romeo M. Bautista 《Agricultural Economics》1993,8(4):345-375
Asian developing countries have had varying experiences in trade and agricultural development in the 1980s, attributable in part to their differing stages of economic development and structural characteristics. Other important influences relate to the external economic environment and the policy choices made by their governments not only during the period but also in the preceding decade. The achievements of Asian developing countries under the adverse external conditions of the 1980s are discussed in terms of their macrocconomic and agricultural growth, the commodity structure of agricultural growth, their food production and trade, the expansion and diversification of their agricultural exports, and the policy and nonpolicy factors affecting them. Special attention is given to the role of policy reforms implemented in China and the South Asian countries, following similar policy developments in Northeast and Southeast Asia in the 1960s and 1970s, toward greater openness in their trade regime and increased private-sector participation in the economy. These reforms have contributed to the observed acceleration in gup , agricultural, and export growth in the 1980s. However, macroeconomic imbalances have emerged that threaten the sustainability of economic liberalization in those countries. The major challenges for the 1990s also differ among the Asian developing countries. In the industrially advanced Northeast economies of Taiwan and South Korea, the primary need is to ease the transition of the remaining rural population as farm incomes continue to fall and workers move to industrial and service activities. This challenge has to be addressed in the context of growing external pressure to further open their domestic market for agricultural imports. Among the Southeast and South Asian countries, there is a need to reduce the existing policy biases against agriculture, particularly against export crop production. Moreover, China and the South Asian countries face the additional challenges of continuing to deregulate their trade regime and internal markets, and of promoting macroeconomic stability. Despite the external trend recently toward regionalism, Asian developing countries generally seem committed to an open trading system, on which in fact their past impressive economic performance has been predicated. An important challenge for them in the 1990s is to play an active role in arresting and reversing any protectionist tendencies arising from the formation of regional trading blocs and to support multilateral initiatives such as the Uruguay Round that promote global trade liberalization. 相似文献

This study develops a scale, using the American Marketing Association’s code of ethics, to measure the marketing-related norms
of marketing practitioners. The scale has five dimensions: 1) price and distribution, 2) information and contracts, 3) product
and promotion, 4) obligation and disclosure, and 5) general honesty and integrity. The relative influence of personal moral
philosophies and organizational ethical climate on the norms of marketers was also examined in this study.
