In this paper, we aim to investigate the optimum values for the termination rate on mobile networks in Brazil. In order to do so, initially we provide an overview of the legal framework on the subject since the privatization in the beginning of the 90's, as well as a market overview of the...

In this paper, we characterize the domestic cargo flows for imports and exports, from and towards the Brazilian ports. Based on this characterization, it is possible to calculate basic competitiveness indicators, for different cargo types. We also present a discussion on minimum efficient scales...

In this paper, we analyze the structure of geographic markets for the port sector in Brazil, identifying influence areas for its main ports. We employed spatial clustering algorithms, based on foreign trade data. We observed that the geographic factor seems to be extremely important in...

In this paper, we present some models to analyze the impacts of surface transportation logistic costs on importers and exporters decisions on which ports to choose for foreign trade operations. We employed a technique based on fractional split distributions, in which the dependent variable...

For many decades over the 20th Century, the mainstream of economics adopted a normative and axiomatic theory of individual behavior in which maximizing procedures were carried out by rationally unbounded agents. This status has been challenged on many grounds and alternative views from fields...

Neste artigo propomo-nos estudar as contribuições que um conjunto de autores da corrente post keynesiana tem feito para esclarecer o sentido e o significado da noção de expectativa seja no quadro teórico como também no quadro político. A influência das expectativas, a tomada de decisões...
