- Induced accident in the maritime sinister of Costa ConcordiaPublication . Oca, Reynaldo Montes de; Madariaga, E.; Delgado, Olga; García, SergioThis study determined by the theory of the Maritime Accidents the causal factors that led to the catastrophe of the passenger´s vessel Costa Concordia. In the study we've applied the key elements of such theory, as they are the pressure of production and/or the pressure of technological advances, acting on the individual risk homeostasis of the operator. After performing this analysis, we set up a discussion in which we have established that this case meets the foundations of the induced maritime accidents (strong core, protector ring, positive and negative heuristics) and the existence of the key elements as were the captain and the first mate. It was established conclusions that these foundations are combined and accumulated in such a way that caused the rupture of the margin of safety, leading to the inevitable. If he had managed to maintain a margin of safety permissible, the sinister passenger vessel Costa Concordia would have been avoided.
- Demand of Mozambique seaportsPublication . Barros, C.P.; Zorro, M. J.; Mendes, Dulce; Delgado, OlgaThis paper presents an Analysis of Mozambique seaports from 2001-2015 using the Anderson, De Palma and Thisse’s ideal type demand model. The seaports of Mozambique serve not only Mozambique but also other countries without acess to sea. For example Beira seaport as a specific train line to Zambia. The ideal type model of Anderson, Palma and Thisse is a model of heterogenous seaports that is estimated in two steps and accounts for endogeneity of the price. The results reveal that the seaport market share increases with income and with the price of container cargo, while decreases with the price of maritime transport services and the price of truck transportation.. The price is endogenous in demand equation and the endogeneity is taken into account in the demand estimation. The price of trucks has a negative coefficient and therefore is a complementary good. Demand elasticities are presented. A robustness test is done estimating also the Berry, Levinsohn, and Pakes approach and comparing the results.
