Rational Model (rational + model)
Selected AbstractsActivist Macroeconomic Policy, Election Effects and the Formation of Expectations: Evidence from OECD EconomiesECONOMICS & POLITICS, Issue 2 2000David Kiefer We examine the explanatory power of a political,business cycle theory in which governments practice short-run policy to lessen the impact of exogenous shocks. Governments have ideological objectives with respect to macroeconomic performance, but are constrained by an augmented Phillips curve. The most prominent version, the rational partisan model, incorporates forward-looking expectations. This model can be compared to a competing model based on backward-looking expectations. Alesina and Roubini's recent advocacy of the rational model uses OECD data. Our reconsideration of the same data, updated to 1995, suggests that the adaptive expectations version offers a better explanation than the rational one. [source] Euclid: Strategic alternative assessment matrixJOURNAL OF MULTI CRITERIA DECISION ANALYSIS, Issue 2 2002Madjid Tavana Abstract The vast amount of information that must be considered to solve inherently ill-structured and complex strategic problems creates a need for tools to help decision makers (DMs) recognize the complexity of this process and develop a rational model for strategy evaluation. Over the last several decades, a philosophy and a body of intuitive and analytical methods have been developed to assist DMs in the evaluation of strategic alternatives. However, the intuitive methods lack a structured framework for the systematic evaluation of strategic alternatives while the analytical methods are not intended to capture intuitive preferences. Euclid is a simple and yet sophisticated multiobjective value analysis model that attempts to uncover some of the complexities inherent in the evaluation of strategic alternatives. The proposed model uses a series of intuitive and analytical methods including environmental scanning, the analytic hierarchy process (AHP), subjective probabilities, and the theory of displaced ideal, to plot strategic alternatives on a matrix based on their Euclidean distance from the ideal alternative. Euclid is further compared to the quantitative strategic planning matrix (QSPM) in a real world application. The information provided by the users shows that Euclid can significantly enhance decision quality and the DM's confidence. Euclid is not intended to replace the DMs, rather, it provides a systematic approach to support, supplement, and ensure the internal consistency of their judgments through a series of logically sound techniques.

LORNE CARMICHAEL Economists use the standard rational model to predict behavior after a policy change and to determine the policy's welfare implications. Recent experimental observations are casting doubt on the predictive accuracy of the standard model, but the more realistic behavioral alternatives often provide a poor basis for making normative evaluations. This paper suggests that we can still predict behavior and measure welfare within the same model. We show that optimizing agents with standard preferences will in some cases behave as if they are subject to an endowment effect. Even so, we may still be able to uncover information about their preferences. [source] Confucian Capitalism and the Paradox of Closure and Structural Holes in East Asian FirmsMANAGEMENT AND ORGANIZATION REVIEW, Issue 1 2010Sun-Ki Chai abstract A long-standing debate has taken place in the organizational sociology and social network literatures about the relative advantages of network closure versus structural holes in the generation of social capital. There is recent evidence that these advantages differ across cultures and between East Asia and the West in particular, but existing network models are unable to explain why or address cultural variation in general. This paper seeks to provide a solution by integrating a culture-embedded rational model of action into the social network model of structure, using this not only to re-examine the closure versus structural hole debate, but also to tie it to the literature on Confucian capitalism and the ,East Asian Model' of the firm. We argue that this integrated approach allows us to systematically analyse the relationship between culture and behaviour in networks and, more specifically, to explain why closure has been a more powerful source of productivity in East Asia than the West. [source] Bandpass filter modeling employing Lorentzian distributionMICROWAVE AND OPTICAL TECHNOLOGY LETTERS, Issue 5 2009Mahmoud Al Ahmad Abstract This letter takes a close outlook of modeling a bandpass filter performance with the Lorentzian distribution function. Lorentzian function parameters are correlated with the filter parameters, namely, its bandwidth and center frequency. The zeros and poles of the filter are extracted from the closed form expression of the Lorentzian function, which is used to construct the rational model of the filter. This procedure is expected to optimize the overall filter performance and to construct a consistent equivalent circuit from its computed poles and zeros. © 2009 Wiley Periodicals, Inc.
