Manipulation of Choice Behavior

We introduce and study the problem of manipulation of choice behavior. In a class of two-stage models of decision making, with the agent's choices determined by three "psychological variables," we imagine that a subset of these variables can be selected by a "manipulator." To what extent does this confer control of the agent's behavior? Within the specified framework, which overlaps with two existing models of choice under cognitive constraints, we provide a complete answer to this question.attention, choice function, revealed preference, satisficing, threshold

Degrees of Belief

A discussion of three kinds of degree of belief: subjective (credal) probability, degree of belief in the maximizing sense (expected epistemic utility) and degree of belief in the satisficing sense (Shackle type degrees of belief). The relations between these concepts and full belief (absolute certainty) and other qualitative assessments of belief (mere belief or plain belief) will be considered

Integrating Knowledge in Organizations: A Lessons Learned Case Study

El paper del coneixement comú a les organitzacions (CKO, en la sigla en anglès) és creixent en la literatura com un tema important; tanmateix, la seva formalització és lenta. Aquesta tesi presenta un model de CKO que descriu la seva relació amb la capacitat organitzativa en el context de les teories de l’empresa. Disseny, metodologia i enfocament Tenint en compte l’estat no sistematitzat del coneixement a les organitzacions i els diversos enfocaments de què és objecte la capacitat organitzativa, en aquest treball s’analitzen textos de les teories del coneixement i de les teories de l’empresa, seguint mètodes de codificació de la grounded theory, amb vista a emmarcar un model per tal d’observar i avaluar casos de CKO que participen en la pràctica productiva. El component de recerca empírica d’aquesta tesi segueix l’estratègia de l’estudi del cas per a la recopilació de dades i de la grounded theory per a la seva anàlisi. El cas correspon a un programa de cooperació internacional interuniversitari, que va durar deu anys, en què s’integren els coneixements en forma de lliçons apreses. Les dades inclouen l’extensa documentació del programa, tres sèries d’enquestes, 16 entrevistes filmades i 36 històries. Aquí, la grounded theory segueix el concepte de sensibilització de Charmaz (2000)per guiar la codificació inicial utilitzant com a referència el marc conceptual desenvolupat. Conclusions El CKO es caracteritza per: a) la tensió en la integració dels coneixements en la pràctica productiva; b) la lògica d’instrumentalitzar eines organitzacionals (OT), y c) els processos pels quals es reconeixen els coneixedors. El CKO funciona com a mediador entre les OT (directives, plans, estructura, arquitectura i rutines) i l’eficiència de la capacitat organitzativa. El CKO apareix no com una eina organitzativa, sinó com els processos relacionats que els instrumentalitzen i per mitjà dels quals els coneixedors són reconeguts i donen forma al sistema interpretatiu de l’organització. Aquesta tesi ofereix criteris de gestió orientats a l’eficiència del CKO (sorgits d’aquesta concepció), amb vista a aplicar eines organitzatives que integren el coneixement en la pràctica productiva, i proposa: a) una visió organitzacional integral de les teories existents del saber; b) un model d’observació d’instàncies del saber a les organitzacions; c) un esquema per tal d’emmarcar les teories de l’empresa, i d) un model per entendre el rol del coneixement comú a les organitzacions.El papel del conocimiento común en las organizaciones (CKO por sus siglas en inglés) se acentúa en la literatura como un tema importante; sin embargo su formalización está rezagada. Esta tesis presenta un modelo de CKO que describe su relación con la capacidad organizacional en el contexto de las teorías de la firma. Diseño, metodología y enfoque: Teniendo en cuenta el estado no-operacionalizado del conocimiento en las organizaciones y los variados acercamientos a la capacidad organizacional, este trabajo entrevista textos de las teorías del conocimiento y de las teorías de la firma, siguiendo métodos de codificación de “grounded theory”, para enmarcar un modelo para observar y evaluar instancias de CKO que participan en la práctica productiva. El componente de investigación empírica de esta tesis sigue la estrategia de estudio de caso para la recopilación de datos, y “grounded theory” para su análisis. El caso corresponde a un programa de cooperación internacional Interuniversitario, que duró diez años, en el que se integra conocimientos en lecciones aprendidas. Los datos incluyen la extensa documentación del programa, 3 sets de encuestas, 16 entrevistas filmadas y 36 historias. Aquí, “grounded theory” sigue el concepto de sensibilización de Charmaz (2000) para guiar la codificación inicial utilizando como referencia el marco conceptual desarrollado. Hallazgos: CKO está caracterizado por la (a) tensión en la integración de conocimientos en la práctica productiva, (b) la lógica de instrumentalizar herramientas organizacionales (OT) y (c) los procesos por los cuales se reconocen a los conocedores. CKO funciona como mediador entre OT (directivas, planes, estructura, arquitectura y rutinas) y la eficiencia de la capacidad organizacional. CKO emerge, no como una herramienta organizacional, sino como los procesos relacionados que los instrumentalizan, y por medio de los cuales los conocedores son reconocidos y dan forma al sistema interpretativo organizacional. Esta disertación ofrece criterios de gestión orientados a la eficiencia (surgidos de esta concepción) de CKO) para aplicar herramientas organizacionales que integran el conocimiento en la práctica productiva, y propone (a) una visión organizacional integral de teorías existentes del saber, (b) un modelo de observación de instancias del saber en organizaciones, (c) un esquema para enmarcar teorías de la firma, y (d) un modelo para entender el rol del conocimiento común en las organizaciones.The role of common knowledge in organizations (CKO) is emphasized in literature as an important topic; however, its formalization has been neglected. This dissertation presents a model of CKO that depicts its relationship with the capability of the organization within the context of theories of the firm. Design/methodology/approach: Considering the un-operationalized status of knowledge in organizations and the several approaches to organizational capability, this work interviews text of the theories of knowing and the theories of the firm, following grounded theory coding methods, to frame a model to observe and assess CKO instances that participate in the productive practice. The research empirical component of this dissertation follows case study strategy for data collection and grounded theory for data analysis. The case corresponds to a ten-year International Inter-university Cooperation Program that integrates knowledge into lessons learned. Data include program extensive program documentation, 3 sets of surveys, 16 filmed interviews, and 36 stories. Grounded theory follows Charmaz (2000) sensitizing concept approach to guide initial coding using the developed framework. Findings: CKO is characterized by the (a) tension of integrating knowledge into the productive practice, (b) logic of instrumentalizing organizational tools (OT), and (c) processes by which knowers are recognized. CKO also operates as mediator between OT (directives, plans, structure, architecture and routines) and the efficiency of the organizational capability. CKO emerges, not as an organizational tool, but as the related processes that instrumentalize them, or by which knowers are recognized and shape the organizational interpretative system. Dissertation offers efficiency oriented managerial criteria (emerged from the CKO conception) for applying organizational tools to integrate knowledge into the productive practice, and proposes (a) an integrated organizational view of extant theories of knowing, (b) a model for observing knowing instances in organizations, (c) a scheme for framing theories of the firm, and (d) a model for understanding the role of common knowledge in organization

Inferring cognitive heterogeneity from aggregate choices

Theories of bounded rationality often assume a rich dataset of choices from many overlapping menus, limiting their practical applicability. In contrast, we study the problem of identifying the distribution of cognitive characteristics in a population of agents from a minimal dataset that consists of aggregate choice shares from a single menu, and includes no observable covariates of any kind. With homogeneous preferences, we find that “consideration capacity” and “consideration probability” distributions can both be recovered effectively if the menu is sufficiently large. This remains true generically when tastes are heterogeneous with a known distribution. When the taste distribution is unknown, we show that joint choice share data from three “occasions” are generically sufficient for full identification of the cognitive distribution, and also provide substantial information about tastes

Accommodating satisficing behaviour in stated choice experiments

Accumulating evidence suggests that respondents in stated choice experiments use simplifying strategies. Such behavior is a deviation from random utility theory and can lead to wrong inferences regarding preferences. This is a first attempt to systematically explore satisficing in stated choice experiments. We consider 944 satisficing rules and allow respondents to revise the rules adopted throughout the choice sequence. Only a minority of respondents used the same satisficing rule across the entire sequence. Allowing for updating reveals that the use of the heuristic changes over the choice sequence. Considering satisficing behavior leads to improved model fits and different marginal willingness-to-pay estimates

Visual judgments of length in the economics laboratory: Are there brains in stochastic choice?

We design an induced value choice experiment where the objects are valued according to only a single attribute with a continuous measure. Subjects have an imperfect perception of the choice objects but can reduce their imperfect perception with cognitive effort. Subjects are given a choice set involving several lines of various lengths and are told to select one of them. They strive to select the longest line because they are paid an amount that is increasing in the length of their selection. This "idealized" choice experiment produces a dataset that is uniquely suited to study apparently random choice. We also manipulate the available cognitive resources of the subjects by imposing either a high or low cognitive load. We find that both choices and the allocation of effort are affected by the material incentives in the choice problem and the available cognitive resources. We find evidence that optimal choices have shorter deliberation times than suboptimal choices, which is consistent with previous theoretical predictions. The distribution of errors can have significant implications for the specification of stochastic choice models. Specifications where errors have a Gumbel distribution appear to provide a better fit than those with a normal distribution. Despite that the cognitive load manipulation affects both choice and search, it is notable that neither the Gumbel distribution results nor the relationship between optimal choice and deliberation time appear to be affected by the available cognitive resources. This perhaps suggests that these results are general and persistent features of choice
