Para tanto, valemo-nos de simulações econômicas, um tipo de abordagem alternativa que usa técnicas matemáticas e deduções para resolver um modelo objetivo. A simulação econômica desta dissertação reflete que o grau de abertura comercial é um fator relevante de peso para possíveis alterações estruturais nas economias. Nota-se que, nos países com baixo grau de abertura, o custo do capital é o principal entrave para o crescimento econômico. E, naquelas economias com alto grau de abertura, a maior dinâmica compensaria os problemas causados pelo custo do capital. Quando comparados os dois tipos de reformas (contínua versus pontual), a reforma "contínua" trará uma qualidade de ganho mais expressivo do produto relativo do que a reforma "pontual". Outra conclusão é que, as economias com maior grau de abertura devem ter uma maior preocupação com respeito à qualidade das suas instituições, devido à maior potencialidade causada pela maior abertura comercial / Abstract: The objective of this work is to discuss some institutional reforms and economic politics related to the growth. Therefore, it is based on economic simulations, a type of alternative approach that uses mathematical techniques and deductions to solve an objective model. The economic simulation of this dissertation reflects that the trade opening level is an important factor of weight for possible structural alterations in the economies. It is noticeable that, in the countries with low opening level, the cost of the capital is the main setback for the economic growth. And, in those economies with high opening level, the largest dynamics would compensate the problems caused by the cost of the capital. When compared the two types of reforms (continuous versus punctual), the "continuous" reform will bring a more expressive gain quality of the relative product than the "punctual" reform. Other conclusion is that, the larger opening level economies should have a larger concern regarded to the quality of its institutions, due to the largest potentiality caused by the largest trade opening / Mestre

The purpose of this thesis is to study the effect of lower milk support prices trigger ed by chronic surplus production problems and to offer alter native management strategies for dairymen caught in the cash flow squeeze precipitated by resulting cuts in the producer price of milk. Historical dairy policy is reviewed and recommendations are offered for consideration in developing dairy policy over the next decade. FLIPSIM V, a powerful, firm-level computerized simulation model is employed to predict the probable outcome of employing alternative management strategies designed to improve profitability for individual dairymen. The study focuses on a typical farm devised from survey data to be representative of Utah's dairy industry. A five-year planning horizon is simulated.

Understanding how innovations are accepted in a dynamic and complex market environment is a crucial factor for competitive advantage. To understand the relevant factors for this diffusion and to predict success, empirically grounded agent-based models have become increasingly popular in recent years. Despite the popularity of these innovation diffusion models, no common framework that integrates their diversity exists. This article presents a flexible, modular and extensible common description and implementation framework that allows to depict the large variety of model components found in existing models. The framework aims to provide a theoretically grounded description and implementation framework for empirically grounded agent-based models of innovation diffusion. It identifies 30 component requirements to conceptualize an integrated formal framework description. Based on this formal description, a java-based implementation allowing for flexible configuration of existing and future models of innovation diffusion is developed. As a variable decision support tool in decision-making processes on the adoption of innovations the framework is valuable for the investigation of a range of research questions on innovation diffusion, business model evaluation and infrastructure transformation.
