Fluid Modelling: A Step Toward More Adequate Modelling
One of the main problems at modelling economic systems is changing of the structure of the system. It is especialy important for economic situation in Yugoslavia during last few years. It’s characteristic is drastic changing of inner relationships as a consequence of the proposed economic reform and hyperinflation trends. This means that the structure of the existing economic system is changing (the structure between main macroeconimic sectors). When the a priori informations about model are unknown, an adaptive model is needed. Adaptability means that it is possible to: (1) change the values of parameters; (2) change the structure of the model so that it corresponds to the changes of the structure of the system under control; (3) modify goals and criterions according to the additional informations about surroundings; (4) change limitations control actions due to changes of available resources. The subject of researches in this work is the “structural adaptability” that is models with unknown input-output mapping operator.
Some experiences with fluid modeling of economic systems
This paper deals with a new approach to modeling of economic systems, called fluid modeling. The main feature of this approach amounts to a revised concept of dynamics. After having established a set of requirements towards economic modeling we represent a practical example on fluid dynamic modeling of a particular macroeconomic system and discuss the extent to which the basic requirements of fluid modeling have been fulfilled.
Foundations of Despotism: Peasants, the Trujillo Regime, and Modernity in Dominican History
This book explores the history of the Dominican Republic as it evolved from the first European colony in the Americas into a modern nation under the rule of Rafael Trujillo. It investigates the social foundations of Trujillo's exceptionally enduring and brutal dictatorship (1930-1961) and, more broadly, the way power is sustained in such non-democratic regimes. The author reveals how the seemingly unilateral imposition of power by Trujillo in fact depended on the regime's mediation of profound social and economic transformations, especially through agrarian policies that assisted the nation's large independent peasantry. By promoting an alternative modernity that sustained peasants' free access to land during a period of economic growth, the regime secured peasant support as well as backing from certain elite sectors. This book thus elucidates for the first time the hidden foundations of the Trujillo regime.
