This article takes a view of strategy which disputes the common distinctions between formulation and implementation, and between programmed and adaptive strategies. It argues that corporate success derives from a competitive advantage which is based on distinctive capabilities, which is most often derived from the unique character of a firm's relationships with its suppliers, customers or employees, and which is precisely identified and applied to relevant markets. Strategy is that process.  相似文献

Vertical relationships – contracts or ownership and control, enable firms to exercise extensive control and influence over a supplier or retailer. Such vertical links can increase firms'competitiveness in a whole range of ways. Some of these – reducing costs through integrating processes or ensuring effective product retailing also serve the consumer interest. Others, preventing retailers from offering competing products, for example, don't; and this explains the suspicion with which such links are often viewed by the competition authorities. The consequence is that strategy for vertical relationships must encompass commercial, economic and legal dimensions. It is a key element in corporate strategy in many industries.  相似文献

We propose a new hierarchical model of online and offline advertising. This model incorporates within-media synergies and cross-media synergies and allows higher-order interactions among various media. We derive the optimal spending on each medium and the optimal total budget. We also develop three hypotheses on the effects of within- and across-media synergies on both the total budget and its allocation. We estimate media effectiveness as well as the within- and cross-media synergies of offline (television, print, and radio) and online (banners and search) ads using market data for a car brand. We show that both types of synergies —within-media (i.e., intra-offline) and cross-media (online-offline)— exist. We show how within- and cross-media synergies boost the total media budget and online spending due to synergies of the online media with various offline media.  相似文献

We analyse the economic risks from two influenza pandemics that represent extremes along the virulence‐infectiousness continuum of possible pandemics: a high virulence–low infectiousness event and a low virulence–high infectiousness event. Our analysis involves linking an epidemiological model and a quarterly computable general equilibrium model. We find that global economic activity is more strongly affected by a pandemic with high infection rates rather than high virulence rates, all else being equal. Regions with a higher degree of economic integration with the world economy face greater risks of negative effects than less integrated regions.  相似文献

Multiperiod linear programming techniques are used to evaluate comparative profitabilities and soil erosion rates for corn grown monoculturally and in rotation with a) soybeans, b) soybeans and oats, c) barley, and d) alfalfa on moderately sloping land with medium loam soils in southern Ontario. Attention is focussed on the case of a highly leveraged recent entrant to farming with heavy debt servicing needs and potential cash flow constraints. Monocultural corn was found to be more profitable than any of the rotational systems, with corn-soybeans rotations the next most profitable and corn-barley rotations the least profitable. Corn-soybeans caused the highest soil erosion, followed by continuous corn, with corn-alfalfa rotations causing the least. Les techniques de programmation linéaire multipériode sont utilisées pour évaluer et comparer les niveaux de profit et les taux d' érosion de sols agricoles moyennement argileux pour des systèmes de production de grandees cultyres localiées dans le sud de l' ontario et produisant, soit du mais en régime de monoculture, soit du mais en rotation avec: a) du soja, b) soja et avoine, c) orge. et d) de la luzerne plantée sur des terrains à pentes modérées. L' analyse developpée dans cet article met l' accent sur des agriculteurs récemment installés, disposant de beaucoup d' actifs, mais également, ayant des besoins énormes d' emprunts et, par conséquent, soumis à des contraintes potentielles sur leurs cash-flows. Les résultats obtenus montrent que le système de production, mais-monoculture, est le plus viable de tous les systèmes etudies. Parmi les systemes de production reposant sur une rotation culturale, il s' avère que celui combinant maïs et soja vienne en seconde position, tandis que un régime cultural fondé sur une rotation maïs et orge donne les pires resultats. Pour ce qui concerne des taux d' erosion des sols, la rotation maïs-soja cause les plus gros dommages. ensuite suivie par le système de production, maïs-monoculture. Finalement, les taux d' erosion les plus faibles ont été obtenus pour la rotation culturale, maïs-luzerne.  相似文献

Chile's Neoliberal Agrarian Transformation and the Peasantry   总被引:1,自引:0,他引:1  
In the mid–1970s, following the early shift to neoliberalism, the Chilean rural sector was restructured dramatically, becoming one of the most successful cases of non–traditional agricultural export (NTAE) growth. However, many analysts fail to discuss the problematic nature of Chile’s integration into the global market. Underpinning this rapid growth of NTAEs is the exploitation of cheap peasant labour, especially seasonal female wage workers. This article examines the elements of continuity and change in agrarian policy since the transition to democracy in 1990. In particular, it presents the policy debate on the future of the peasantry: capitalization or proletarianization? The dilemma that policy makers face over maintaining high rates of NTAE growth while at the same time attempting to reduce poverty and income inequalities are also highlighted. The Chilean case can be considered as paradigmatic insofar as it exhibits key characteristics of the classical capitalist transformation of agriculture: the emergence of a new class of dynamic agricultural entrepreneurs, renewed proletarianization and land concentration, and intensification of social differentiation.  相似文献

This paper documents the purposes of issuer tender offers to repurchase stock, as stated in Securities and Exchange Commission (SEC) disclosures, over the period 1994‐2006. We explore whether stated purposes relate to announcement period returns and find returns are significantly lower when repurchases replace dividends, distribute cash from unspecified sources, or occur subsequent to third‐party tender offers. Announcement period returns are significantly higher when repurchases are viewed by management as the best investment opportunity available or when they occur subsequent to previous repurchase programs. Finally, we find evidence in support of signaling theory and Jensen's (1986) agency cost of free cash flow theory.  相似文献

In this paper, we develop a multi-sectoral computable general equilibrium tax model for Italy allowing for a number of fiscal tools. We illustrate the methodology for modelling and accommodating the full range of direct and indirect taxes into the national general equilibrium model. In particular, we build a commodity tax matrix by commodity, source, user and tax type; and a production tax matrix by industry and tax type. We also put a special emphasis on the institutional sector accounts, incorporating a detailed system of equations. Our model provides a powerful tool for acquiring new insights in fiscal policy analysis, through the assessment of tailored tax reforms, which can consist of either changes in tax rates and tax bases for indirect and direct taxes. Finally, to validate the model we perform an equalizing Value-Added-Tax rates reform. We find that a budget-neutral uniform tax rate reform would be GDP and welfare improving. However, results across agents and sectors vary.  相似文献
