THE VERTICAL COORDINATION CONTINUUM AND THE DETERMINANTS OF FIRM-LEVEL COORDINATION STRATEGY

A number of past authors have argued that vertical coordination strategies lie along a continuum running from spot markets to vertical integration. However, the strategies that make up the middle of this continuum have remained ill defined and the sense in which the continuum is truly a continuum has not been made specific. This paper attempts to define the continuum and its "middle" strategies in such a manner that the continuum is truly a continuum has not been made specific. This paper attempts to define the continuum and its "middle" strategies in such a manner that the continuum becomes a useful means by which firm-level decision makers could examine their options for vertical coordination strategy.Industrial Organization,

STRATEGIC CHOICE ALONG THE VERTICAL COORDINATION CONTINUUM

Fundamental changes are underway in the U.S. agri-food system, changes that are altering traditional marketing relationships. Parts of the food system are becoming tightly integrated, such as the poultry subsector and, increasingly, the pork subsector. The tightening of vertical linkages has been characterized by movement from open markets to various forms of managed coordination, e.g. contracting, strategic alliances, and single ownership of multiple market stages. 1998 AAEA SymposiumIndustrial Organization,

Evaluation and study of advanced optical contamination, deposition, measurement, and removal techniques

A program is described to design, fabricate and install an experimental work chamber assembly (WCA) to provide a wide range of experimental capability. The WCA incorporates several techniques for studying the kinetics of contaminant films and their effect on optical surfaces. It incorporates the capability for depositing both optical and contaminant films on temperature-controlled samples, and for in-situ measurements of the vacuum ultraviolet reflectance. Ellipsometer optics are mounted on the chamber for film thickness determinations, and other features include access ports for radiation sources and instrumentation. Several supporting studies were conducted to define specific chamber requirements, to determine the sensitivity of the measurement techniques to be incorporated in the chamber, and to establish procedures for handling samples prior to their installation in the chamber. A bibliography and literature survey of contamination-related articles is included

Quantifying Strategic Choice Along the Vertical Coordination Continuum

The qualitative and quantitative results of a study undertaken to test a decision framework firms might consider in choosing a vertical coordination strategy are presented. The posited five-step decision making process tested that a change in coordination strategy would occur if and only if a "yes" decision was made at each step. The results reported as case-based frequencies and as a discriminate analysis function provide strong support for the study's research propositions. The ability of an alternative to reduce the costliness of a coordination error and the acceptability of the risk/return tradeoff were critical to the willingness of a sample of producers to change coordination strategy. Implementability was significant, but not to the same extent as costliness of a coordination error or acceptability of the risk/return tradeoff.vertical coordination, vertical coordination continuum, discriminate analysis, willingness to change, unwillingness to change, coordination error, programmability, implementability, risk/return tradeoff, Industrial Organization,

Influence of organic films on the evaporation and condensation of water in aerosol

Uncertainties in quantifying the kinetics of evaporation and condensation of water from atmospheric aerosol are a significant contributor to the uncertainty in predicting cloud droplet number and the indirect effect of aerosols on climate. The influence of aerosol particle surface composition, particularly the impact of surface active organic films, on the condensation and evaporation coefficients remains ambiguous. Here, we report measurements of the influence of organic films on the evaporation and condensation of water from aerosol particles. Significant reductions in the evaporation coefficient are shown to result when condensed films are formed by monolayers of long-chain alcohols [C(n)H((2n+1))OH], with the value decreasing from 2.4 × 10(−3) to 1.7 × 10(−5) as n increases from 12 to 17. Temperature-dependent measurements confirm that a condensed film of long-range order must be formed to suppress the evaporation coefficient below 0.05. The condensation of water on a droplet coated in a condensed film is shown to be fast, with strong coherence of the long-chain alcohol molecules leading to islanding as the water droplet grows, opening up broad areas of uncoated surface on which water can condense rapidly. We conclude that multicomponent composition of organic films on the surface of atmospheric aerosol particles is likely to preclude the formation of condensed films and that the kinetics of water condensation during the activation of aerosol to form cloud droplets is likely to remain rapid

When Consumers Diet, Should Producers Care? An Examination of Low-Carb Dieting and U.S. Orange Juice Consumption

From 2000 through 2004, per-capita orange juice purchases decreased by 12.3 percent in the United States, while the popularity and media coverage of low-carbohydrate dieting exploded. Content analysis was used to count selected newspaper articles topically related to low-carbohydrate dieting, the Atkins diet, and the South Beach diet. These data were included in a national orange juice demand model, where purchase data served as the independent variable and proxy for consumer demand of orange juice. Results indicate that media coverage of low-carbohydrate diets and dieting was negatively and significantly related to demand for orange juice in the United States.Food Consumption/Nutrition/Food Safety,
