The Value of Simple Models
نویسنده
چکیده
Neoclassical economic theory predicts equilibrium, yet the prediction is based on a string of patently absurd assumptions. Furthermore, evidence for instability is pervasive in the behaviour of real economies, implying that real economies are far from equilibrium and their behaviour potentially complex or chaotic. Therefore the neoclassical approach to understanding the behaviour of economies is futile and misleading [1], as many heterodox economists understand.

Monologism of Hofstede’s Static Model vs Dialogism of Fang’s Dynamic Model: Contradictory Value Configuration of Cultures through the Case Study of Farsi Proverbs
Among various cultural models, the dichotomy of static versus dynamic models has provided a fertile ground for research. Although a number of static models are suggested, the dominant trend in almost all static models is provided by Hofstede who focuses on cultural differences along four major dimensions (power distance, individualism, uncertainty avoidance, and masculinity) and reduces “the co...

In the present research, the performances of six empirical models, i.e., simple threshold exceedance, fixed proportion exceedance, quadratic function of storage, power function of storage, cubic function of storage, and exponential function of storage were investigated for estimation of groundwater potential recharge in a semi-arid region. First, the FAO Dual Crop procedure was used to calibrat...

Two relatively simple analytic Models for investigation of fast ignition dynamics are developed, that are the subsonic and the supersonic models. On the basis of the subsonic model, which a pre-compressed fuel of density is heated by a subsonic thermal wave, the beam energy and the intensity required for ignition is closely related to proton range. Whereas, on the basis of supersonic model, fo...
متن کاملThe Uniqueness of the Overall Assurance Interval for Epsilon in DEA Models by the Direction Method
The role of non-Archimedean in the DEA models has been clarified, so that the associatedlinear programs can be infeasible (for the multiplier side) and unbounded (for theenvelopment side) with an unsuitable choice of . This paper shows that the overallassurance interval for in DEA models is unique by the concept of extreme directions. Also,it presents an assurance value for using only s...

The present work demonstrates the successful application of a simple active vibration control procedure based on structural dynamics. Based on mathematical and structural dynamics’ theories, the appropriate locations of sensor and actuator locations of the smart structure are predicted. Also, the optimum value of actuator force which controls the structural vibrations as quickly as it is possib...
متن کاملUsing Non-Archimedean DEA Models for Classification of DMUs: A New Algorithm
A new algorithm for classification of DMUs to efficient and inefficient units in data envelopment analysis is presented. This algorithm uses the non-Archimedean Charnes-Cooper-Rhodes[1] (CCR) model. Also, it applies an assurance value for the non-Archimedean using only simple computations on inputs and outputs of DMUs (see [18]). The convergence and efficiency of the ne...
