ttsm researcher cited in OECD report

15CSPA_Mega-Ships-1

Carlos Pais Montes, researcher of the TTSM researching group has been cited in the OECD report “The Impact of Mega-Ships“, as a result of the interventions made in the OECD/ITF headquarters in Paris, last April 10th.

Container ships have grown incessantly over recent decades due to a continuous search for economies of scale by shipping lines. In the past this has contributed to decreasing maritime transport costs that facilitated global trade. However, the increase in container ship sizes and the speed with which that happens has consequences for the rest of the transport chain. They require infrastructure adaptations and productivity levels that increase costs for port operators, port authorities and other stakeholders in the supply chain. Moreover, mega-ships cause peaks in ports and put a strain on hinterland transports. Has a tipping point been reached, where further increases in ship size result in disproportionally higher port and hinterland costs? What are the impacts of mega-ships for the whole transport chain, and what could be done to optimise the use of mega-ships and mitigate negative impacts?

The study aims to answer these questions through a detailed assessment of the consequences of mega-ships for the different parts of the transport chains: maritime transport, ports, terminals and hinterland transport. This report is part of the International Transport Forum’s Case-Specific Policy Analysis series. These are topical studies on specific issues carried out by the ITF in agreement with local institutions.

Análisis de series temporales: alguna bibliografía sobre wavelets y series de datos económicos

Las técnicas de análisis espectral basadas en la transformada de Fourier son conocidas en el ámbito de la física y de la ingeniería, pero no tanto en el de la economía, debido a la dificultad matemática de alguno de sus desarrollos.

Sin embargo, si buscamos literatura científica, existe una creciente bibliografía utilizando exitosamente esta metodología para el análisis de series temporales de datos macroeconómicos. En particular, la utilización de wavelets se está configurando como un ámbito estrella de trabajo para economistas que buscan métodos descriptivos y predictivos potentes.

A continuación presentamos una selección de alguno de estos artículos, analizando tipos de interes, inflación, precios del petróleo y ciclos económicos con esta aproximación matemática:
