Tax principles, product differentiation and the nature of competition

We analyze the choice between the origin and destination principles of taxation when there is product differentiation and Bertrand competition. If taxes are redistributed to consumers and demand is linear the origin principle dominates the destination principle whatever the degree of product differentiation and extent of economic integration. With nonlinear demand the origin principle dominates if there is sufficient economic integration. When the social value assigned to tax revenue is higher than the private value, the destination principle dominates for intermediate values of product differentiation and economic integration. The same results are also shown to hold with Cournot competition.

Essays on international prices and the subjacent market structure

Esta tese utiliza a informação contida em preços internacionais para identificar parâmetros de modelos de comércio sob competição imperfeita, desta forma permitindo inferência sobre o comportamento das exportações, sobre os ganhos de troca da abertura comercial e sobre a variedade de bens produzidos domesticamente. Em primeiro lugar, investigamos o repasse cambial, no longo prazo, para os preços praticados por exportadores brasileiros. O foco no longo prazo permite controlar os efeitos da rigidez de preço no curto prazo, de maneira que o repasse incompleto evidencie competição imperfeita com preços flexíveis. Em segundo lugar, calculamos os ganhos de troca de novas variedades de bens importados baseando-nos em estimativas para as elasticidades de substituição desagregadas. Finalmente, qualificamos a ênfase da literatura de comércio em ganhos de eficiência no lugar de ganhos de variedade, demonstrando que a variedade de bens produzidos domesticamente se amplia após aberturas comerciais desde que as firmas tenham uma margem de decisão em bens intermediários ou na qualificação da mão de obra.

An experience on mechatronics teaching on undergraduate students by means of the Skybot platform: from classroom to robot competition

This paper analyzes the learning experiences and opinions from a group of undergraduate students in a course about Robotics. The contents of this course were taught as a set of seminars. In each seminar, the student learned interdisciplinary knowledge of computer science, control engineering, electronics and other fields related to Robotics. The aim of this course is that the students are able to design and implement their own and custom robotic solution for a series of tests planned by the teachers. These tests measure the behavior and mechatronic features of the students' robots. Finally, the students' robots are confronted with some competitions. In this paper, the low-cost robotic architecture used by the students, the contents of the course, the tests to compare the solutions of students and the opinion of them are amply discussed.

Las interacciones organizacionales desde la visión ecológica: la competencia

Como parte del trabajo de doctorado de la Señora Ángela Lucia Noguera Hidalgo, el presente documento reúne un compilado de las diversas fuentes relacionadas con el concepto biológico de la “competencia” y su relación con las organizaciones. Es un trabajo en donde a partir de las investigaciones ya existentes se realiza un resumen concienzudo sobre el tema, logrando de este modo un estado del arte.

Interferěncia da comunidade infestante sobre plantas de Eucalyptus grandis de segundo corte

Currently Brazil is one of the leading paper and pulp producers in the world market, where Sao Paulo State boasts the greatest production. Because of the pulp prices falling in the world market and the low costs of a second coppice rotation, two experiments (started May and December, 2000) were conducted to evaluate the effects of weeds and of weed-free periods (0, 3, 6, 9, 12, 15 and 18 months) on the growth of Eucalyptus grandis second coppice plants. The field trials were set up in a randomized block design with four replicates and the experimental plots consisted of three rows of fve plants. The December weed community was composed mainly of Brachiaria decumbens (Surinam grass) and Panicum maximum (Guinea grass) and the May weed community was composed mainly by B. decumbens and Digitaria insularis (Sour-grass). Weeds had a low negative influence on growth, diameter development and macronutrients content of E. grandis second coppice plants. In both experiments, slight reductions in growth were observed only between the fully weeded and weed-free periods, after 18 months.
