On randomization, modeling and experimental design; a new example in an old discussion

Fisher and "Student" quarreled in the early days of statistics about the design of experiments, meant to measure the difference in yield between to breeds of corn. This discussion comes down to randomization versus model building. More than half a century has passed since, but the different views remain. In this paper the discussion is put in terms of artificial randomization and natural randomization, the latter being what remains after appropriate modeling. Also the Bayesian position is discussed. An example in terms of the old corn-breeding discussion is given, showing that a simple robust model may lead to inference and experimental design that outperforms the inference from randomized experiments by far. Finally similar possibilities are suggested in statistical auditing.     

Scarcity effects on value: A quantitative review of the commodity theory literature

Commodity theory (Brock, 1968) deals with the psychological effects of scarcity. According to the theory, scarcity enhances the value (or desirability) of anything that can be possessed, is useful to its possessor, and is transferable from one person to another. This article introduces commodity theory to the marketing literature, reports a meta-analysis of studies designed to test the theory, and discusses the marketing implications of the theory along with suggestions for future marketing research.     

The Effect of Information Systems on Honesty in Managerial Reporting: A Behavioral Perspective*

This study examines the behavioral impact of an information system, and how that impact varies with the information system's precision, in an internal reporting environment. We propose that a manager's reporting decisions are affected by his or her trade‐off of the benefits of appearing honest against the benefits of misrepresentation. The information system affects the manager's trade‐off by improving the owner's ability to make an inference regarding the manager's level of honesty. Thus, to the extent that the manager perceives benefits to appearing honest, the presence of an information system can increase managerial honesty. As the information system becomes more precise, however, the manager must forgo greater benefits of misrepresentation in order to achieve the same appearance of honesty. For managers under a precise system, this will shift the trade‐off decision toward the benefits of misrepresentation and away from the benefits of appearing honest. Notably, in our experiment, the only benefit of appearing honest is an intrinsically motivated desire for social approval. We find that, although the existence of an information system increases managerial honesty, honesty is lower under a precise than under a coarse information system. We also compare profit earned by the owners in our experiment, which relies on a behavioral role of an information system, with the maximum profit theoretically possible given a contractual use of the information system. This comparison suggests that, unless the available information system is sufficiently precise, the owner will obtain greater profits by not contracting on its output, even if that output is fully contractible.     

A Hedonic Price Analysis of Farmland Option Premiums Under Urban Influences

An emerging theory, real option pricing, suggests that an important component of urban fringe farmland values may be the option value arising from nearby urban development. This new option pricing theory, as opposed to its standard conventional counterpart in finance, incorporates both the uncertainty about the future net benefits of a land conversion decision and the irreversibility of this action taken. We demonstrate that parsimonious empirical hedonic models of the errors‐in‐variables type, when corrected for heteroskedasticity, can provide adequate representations of farmland option premiums. Data for a random sample of cash rented Ohio farmland parcels are used, and the impacts of urban development on farmland option premiums are estimated. Results provide evidence that (a) both land‐use conversion probability and urban influences have been important factors affecting the option value of the state's farmland, and (b) these option premiums associated with irreversible and uncertain land development are capitalized into farmland values. Une nouvelle théorie, l'évaluation des options réelles, semble indiquer qu'un élément important de la valeur des terres agricoles périurbaines pourrait être la valeur d'option découlant du développement urbain avoisinant. Cette nouvelle théorie, contrairement aux options financières, inclut à la fois l'incertitude quant aux bénéfices nets futurs liés à la décision de convertir une terre et l'irréversibilité de cette décision. Nous avons démontré que les modèles empiriques parcimonieux et hédoniques du type erreurs sur les variables peuvent, une fois l'hétéroscédasticité corrigée, donner des présentations adéquates des prix de l'option des terres agricoles. Nous avons utilisé les données d'un échantillon aléatoire de parcelles de terres agricoles louées au comptant en Ohio et nous avons estimé l'impact du développement urbain sur le prix de l'option des terres agricoles. Les résultats ont montré: a) que la probabilité de conversion de l'utilisation des terres et les influences urbaines sont des facteurs importants qui influent sur la valeur de l'option des terres agricoles de l'État; b) que ces prix de l'option associés à un aménagement urbain irréversible et incertain sont intégrés dans la valeur des terres agricoles.     

Internet adoption and use in small firms: internal processes, organisational culture and the roles of the owner-manager and key staff

Emerging from a study of Internet adoption in UK Midlands manufacturing small firms is a new typology characterising owners and key staff as Warriors, Interpreters, Clerks and Priests. This typology is used to explore the impacts of internal factors and organisational culture on innovation and new technology usage in small firms.     

CONCEPTUALIZING THE GOAL AND SYSTEM MODELS OF ORGANIZATIONAL EFFECTIVENESS —IMPLICATIONS FOR COMPARATIVE EVALUATION RESEARCH

The lack of comparative evaluation research on organizational-effectiveness models is the primary focus of this discussion. Problems in conceptually and operationally defining evaluation models, such as those in the goal and system model classes, are the proposed reason for this lack of comparative research. In this paper, goal and system models are formally defined in terms of their historical origins, underlying criteria and differing methods of application. A goal and system model classification continuum is also presented. Five comparative evaluation research questions are proposed and their implications for research are discussed. From a theoretical perspective this paper attempts to go beyond the sound foundation laid by Campbell (1977) in his discussion of these two schools of thought on organizational effectiveness.
