There are some kinds of violent conflicts between factions in which one generation of belligerents trains a successive generation to continue and/ or enlarge the scale of conflict in an arena where the hostilities are internecine A model is developed of the devolution of internecine conflict using the lexicon of game theory and the simple mathematics of probability Assumptions pertaining to the behavior and attitudes of factions are transcribed into mathematics to formulate a theory of conflict resolution The theory is general enough to be applied to the struggles in the Middle East as well as to warfare among youth gangs The chief proposition to emerge from the analysis demonstrates how the statistical incidence of aggressive and peaceable factions varies over time The time path has the characteristics of a stochastic process with estimable parameters  相似文献

In this model, the standard theory of the one-person household is extended into space and time. The theory is extended into space by imposition of a real trip cost on the act of purchase, separate from the money price of commodities. It is extended into time by imposition of a real cost of storage (represented by “deterioration”) on the stocks of goods held in the household between shopping trips. The necessity for storage permits the theory to include an endogenous choice of capacity to store as well as choices among consumption, leisure, and shopping trip frequency. By use of duality theory, the comparative static effects of price, wage, and trip costs are examined. Production and transformation within the household are integrated into the model and shown to be covered by the dual approach.  相似文献

The theory of estimation and inference in a very general class of latent variable models for time series is developed by showing that the distribution theory for the finite Fourier transform of the observable variables in latent variable models for time series is isomorphic to that for the observable variables themselves in classical latent variable models. This implies that analytic work on classical latent variable models can be adapted to latent variable models for time series, an implication which is illustrated here in the context of a general canonical form. To provide an empirical example a latent variable model for permanent income is developed, its parameters are shown to be identified, and a variety of restrictions on these parameters implied by the permanent income hypothesis are tested.  相似文献

We study the influence of reason and intuition on decision‐making over time. Facing a sequence of similar problems, agents can either decide rationally according to expected utility theory or intuitively according to case‐based decision theory. Rational decisions are more precise but create higher costs, though these costs may decrease over time. We find that intuition will outperform reason in the long run if individuals are sufficiently ambitious. Moreover, intuitive decisions are prevalent in the early and late stages of a learning process, whereas reason governs decisions in intermediate stages. Examples range from playing behavior in games like chess to professional decisions during a manager's career. Copyright © 2015 John Wiley & Sons, Ltd.  相似文献

Experiments in economics are expensive in terms of dollars and time. This suggests that efficient design is crucial, and that there is a need for econometricians to extend design theory to handle peculiarities of economic experimentation. This paper concerns optimal experimental design for various time series models. Examples are presented illustrating the improvement in estimation accuracy that can be obtained.  相似文献

This paper shows how sectors in the Chinese stock market are connected and investigates risk spillovers across these sectors. Using graph theory and a recently developed time series technique, we are able to identify the systemically important sector in the market and the patterns of risk spillovers across sectors over time. Unlike standard econometric modeling, graph theory enables us to approach this question in a more reader-friendly way. The empirical results show that Industrial sector plays a central role and should thus be considered the systemically most important sector in the Chinese stock market. The spillover structure is found to be time-varying. While Industrial sector dominates the system for most of the time, other sectors such as Consumer Discretionary sector also occasionally appear as the central sector. Our empirical results also indicate that the simple correlation-based approach can produce equally useful information as more advanced econometric models.  相似文献

In theory, time series models can provide more accurate predictions than econometric models. However, time series models do so by introducing bias. To marketing managers who are interested in planning as well as forecasting, lack of bias is more important than accuracy.  相似文献

This paper offers a more general theory of residential location as an alternative to the ‘trade- off’ model. The theory takes account of multiple employment centers, time as well as income constraints, environmental quality, non-work trips, local jurisdictions, the restricted number of houses available for occupation at any time and the constraints on choice imposed by the search process. The result is a very irregular bid rent surface. Its implications for the aggregate rent surface are discussed.  相似文献

Extending research on implicit theories to the leadership domain, we examined how individual differences in belief about the malleability of leadership ability influenced responses to stereotype threat. The study consisted of two time periods. At time 1, we assessed individual differences in implicit theories of leadership ability and self‐efficacy for leadership. At time 2, we activated a stereotype threat in a high‐stakes environment. Results revealed that women reported lower self‐evaluation after a stereotype threat when they had low self‐efficacy and believed leadership ability to be fixed (entity theory) rather than malleable (incremental theory). Results are discussed in terms of how implicit theories generate a network of allied cognitions and emotions that subsequently predict stable patterns of behavior.  相似文献

Abstract Since its origins in the 1950s, the notion of bounded rationality has been incorporated into economic theory using an array of methodological approaches. This paper presents a taxonomy by which these approaches can be categorized and understood, evaluating each approach against a range of important criteria. At a time when the foundations of economic theory are being re‐examined, this paper should be viewed as a first step towards an assessment of the appropriate role that this more realistic view of cognition should take in different areas of economic theory, and also of the desirable characteristics of models that incorporate it.  相似文献

This paper reviews and extends the theory of price and quantity indices which are defined as line integrals, the two types being those of Divisia and Montgomery. The properties of these indices are systematically explored, whereby in particular attention is paid to the path-(in)dependency issue. Two sections discuss the problem of how to approximate the line integral indices when only data at discrete points of time are available. It appears that every bilateral index can be conceived as the outcome of a line integral index over a particular curve in price–quantity space. The classical position is that chained bilateral indices are rationalized by Divisia indices. This rationalization is only interesting when the Divisia indices themselves possess a proper foundation in economic theory. The final sections are therefore devoted to the role played by the Divisia indices in micro-economic theory.  相似文献

This paper applies the theory of consumer choice to investigate the variations in the value of a marginal reduction in commuting for motorists. Two models are developed: Model I includes leisure and goods in the utility function and Model II adds commuting time to the utility function. Model I predicts that the value of a marginal reduction in commuting time increases as income or commuting time increases and decreases as commuting time saved increases. Model II does not have clear qualitative implications. The empirical tests generally support Model I.  相似文献

Developing Stakeholder Theory   总被引:15,自引:0,他引:15  
Previous literature has led to a lack of appreciation of: the range of organization/stakeholder relations that can occur; the extent to which such relations change over time; as well as how and why such changes occur. In particular, extremely negative and highly conflicting relations between organizations and stakeholders have been ignored. Due to this lack of appreciation it is argued that current attempts at integrating the separate strands of stakeholder theory to achieve a convergent stakeholder theory are premature. A model is presented which combines stakeholder theory with a realist theory of social change and differentiation. This model is intended to highlight why it is important to distinguish different stakeholders. The model also enables an analysis of the organization/stakeholder relationship, which is not exclusively from the organization perspective and which is capable of illuminating why and how organization/stakeholder relations change over time. The history of Greenpeace is used as an example.  相似文献
