ORGANIZATIONAL PURCHASE DECISION MAKING: INFORMATION-PROCESSING STRATEGIES AND EVOKED SETS OF QUALIFIED SUPPLIERS

LeBlanc, Ronald Peter January 1981 (has links)
This research project specifically investigates the use of information processing strategies by organizational buyers in the first stage of the supplier selection process, the selection of an evoked set of qualified suppliers. In this selection process it is hypothesized that the buyer's use of evaluation functions or information processing strategies is influenced by the task faced by the buyer. The varying levels of risk, familiarity and informational requirements of the buying situation should impact the use of the information processing strategies. Structured protocols--written descriptions of compensatory and noncompensatory information processing strategies--were used to determine the evaluation function which organizational buyers use to qualify suppliers into an evoked set. The data was collected in a field study of 135 organizational buyers from 76 different organizations. The subjects were interviewed about purchases they were presently working on in which suppliers had been selected but the final purchase decision was still pending. Identification of the buying task, new task, modified rebuy, and straight rebuy also utilized the structured protocol technique. Written descriptions, based on the constitutive definitions of Robinson and Farris (1967), were used to address the following research question: Is there a difference in the decision rules or information processing strategies utilized by organizational buyers in the development of an evoked set of qualified suppliers when the buyer is qualifying suppliers for a new task, modified rebuy, or straight rebuy buying task? In addition to the information gathered via the structured protocols, information was gathered about the level of risk, familiarity and information requirements of the purchasing task. This was done to gain a better understanding of the use of information-processing strategies by organizational buyers. Analysis of the data indicates that the buying task is related to the choice of an information-processing strategy. The data also support the contention that the organizational buyer will utilize any of the information-processing strategies in the selection of an evoked set of suppliers. Although the buying task was found to significantly influence the use of the information-processing strategies, the study shows that all of the strategies were reported as being used for each of the buying tasks. In addition to finding that the buying task influences the choice of an information-processing strategy, the data support the model of information processing presented. The model addressed the impact that risk, familiarity, and information load had on the use of the evaluation functions. The risk node of the model was supported by two of the five risk variables included in the study: product homogeneity and supplier homogeneity. At the familiarity nodes of the model, the subjective measures of familiarity which support the model are supplier familiarity and frequency of product purchase. Supplier familiarity was found to be significantly different between the weighted and unweighted compensatory strategies. The significant difference in the level of familiarity found in the use of the conjunctive and disjunctive information processing strategies is associated with the frequency of product purchase. The final nodal section of the information-processing model which was supported is the comparison of the conjunctive and lexicographic strategies. The lexicographic strategy was found to be used when there was a higher perceived number of suppliers capable of supplying the needed product. In general this study has shown that the situation in which suppliers are selected impacts the use of an information-processing strategy. The findings are consistent with the research and hypothesizing associated with the use of information-processing strategies by consumers.

The impact of taxation and financial factors on company investment : an examination using UK panel data

Devereux, Michael Peter January 1990 (has links)
This thesis examines the impact of taxation and financial factors on the level of investment in fixed assets by quoted manufacturing companies in the United Kingdom between 1971 and 1986. Its most important theme is that there exist substantial differences between companies in the way that they are affected by both taxation and financial factors. The empirical work therefore uses individual company accounting and stock market data (described in Appendix A) together with a detailed model of the corporation tax system (described in Appendix B) in order to exploit cross sectional as well as time series variation. Chapters 2 and 3 investigate the role played by taxation in the investment decision. Part of the cross sectional variation in taxation arises through 'tax exhaustion', caused by the asymmetric treatment of taxable profit and loss in UK corporation tax and restrictions on the use of the imputation system. Two investment equations, the first based on Tobin's Q and the second on the cost of capital in an Euler equation framework are developed from the same neoclassical model of the firm which explicitly models tax exhaustion and the role played by expectations. Each is a forward-looking model, which could be used for the purposes of simulating the effects of tax reform on investment, whether the reform is announced or unannounced, permanent or temporary. The results confirm that tax does play a role in the determination of investment, although, for various reasons, the precise effect is difficult to quantify. They also suggest that the Q model is a poor means of assessing the impact of taxation on investment and that it is dominated by the second model. Chapters 2 and 3 also consider the impact of taxation on company financial policy, and, in particular consider various regimes in which the company may find itself which depend on tax exhaustion and agency costs of debt. The stability of these regimes is more complex than commonly argued in the literature. The appropriate definition of the cost of capital is also developed further, under similar conditions, and a matrix of nine possible values is constructed, depending on the marginal source of finance in this period and the next period. Chapter 4 discusses the role played by financial factors. A model with legal constraints on financial behaviour and agency costs on debt is developed which predicts that, for all firms, investment depends on the level of cash generated, as well as Tobin's Q. The importance of cash flow for firms of different size and age is investigated. The results support the hypothesis that cash flow is a significant determinant of investment for all firms. Cash flow has the highest impact for large and new firms.

Social information and its 'usefulness' in the juvenile court : An analysis of magistrates' accounts in organizational context

Brown, S. January 1989 (has links)
Studies of social information use have generally adopted an objectivist definition of 'information', treating it as an entity which resides in documents such as social enquiry reports and whose effect can then be measured as the corr7latio~ of inpu~ (information) with output (decision). Cons~derat1on of mag1strates' perceptions has been partial and problematic. The present study seeks to effect two major, interrelated, shifts in the study of social information use. Firstly, utilising the sociologies of knowledge and science, information is redefined as a product of the active creation of knowledge representations from data by decision makers. The creation of representations is seen to occur according to conventions of interpretation, generated as decision-makers seek to render their everyday activities coherent and meaningful, and acting as a cultural resource to assist in the accomplishment of future practices. However, information-creation is never neutral. In relating to practices it embraces the character of social relations and the assymetries of power inhering in these. A 'knowledge/power' analysis is adopted which enables 'information' to be viewed in relation to the micro-processes of organizational arenas and to social relations across time and space. Secondly,this forms the context for an empirical study of the generation and deployment of social information-as-representations in the juvenile court. Magistrates were interviewed and observation undertaken in six juvenile courts. The focus is on the decoding of social data by magistrates, both from social enquiry reports and other sources (solicitors, parents, defendants themselves). In decoding social data magistrates utilise conventions of interpretation which are dominated by a search for disciplinary control indicators. Reports are seen as malleable resources whose use is determined more by the decoding context into which they are sent than by their intrinsic properties. Control indicators are manufactured from social data to render the business of tariff sentencing possible and meaningful; the deployment of social information is a fulcrum of the classification of offenders along the 'slippery slope' of bifurcatory sentencing. Magistrates' accounts are thus situated in relation to the practices of the court and interorganizational boundaries, and ultimately are related to 'long distance' control. The 'social enquiry' is found to be, not a narrowly mundane matter of providing 'information for the court', nor solely a locally exerted power, but a far reaching technique of power which must be situated in relation to concepts of the 'tutelary complex' and the 'carceral continuum'.
