Is the Border Effect an Artefact of Geographical Aggregation?
2011
The existence of a large border effect is considered as one of the main puzzles of international macroeconomics. We show that the border effect is, to a large extent, an artefact of geographic concentration. In order to do so we combine international flows with intra-national flows data characterised by a high geographic grid. At this fine grid, intra-national flows are highly localised and dropping sharply with distance. The use of a small geographical unit of reference to measure intra-national bilateral trade flows allows to estimating correctly the negative impact of distance on shipments. When we use sector disaggregated export flows of 50 Spanish provinces in years 2000 and 2005 split…
Rethinking Regional Competitiveness: Catalonia's International and Interregional Trade 1995-2006
2009
Studies of competitiveness tend to focus on a local economy's global interactions, particularly its international trade. But for countries that are at least mid-sized (such as Spain), interregional trade tends to be as large as or significantly larger than international trade. The case of Catalonia illustrates the importance of interregional flows in truly analyzing and devising strategies for a region's external competitiveness. Accounting for interregional trade changes and performing analyses of Catalonia's overall merchandise trade balance, which sectors generate external surpluses as opposed to deficits, and who Catalonia's key trading partners are, and the use of a gravity-model appro…

Sourcing african ivory in chalcolithic Portugal
2009
A recent review of all ivory from excavations in Chalcolithic and Beaker period Iberia shows a marked coastal distribution – which strongly suggests that the material is being brought in by sea. Using microscopy and spectroscopy, the authors were able to distinguish ivories from extinct Pleistocene elephants, Asian elephants and, mostly, from African elephants of the savannah type. This all speaks of a lively ocean trade in the first half of the third millennium BC, between the Iberian Peninsula and the north-west of Africa and perhaps deeper still into the continent.

Effect of two novel bio-based rejuvenators on the performance of 50% RAP mixes - a statistical study on the complex modulus of asphalt binders and as…
2019
An experimental study was conducted to evaluate the effectiveness of two bio-additives as rejuvenators on the properties of asphalt mixtures containing 50% RAP and their binder constituents containing 37% RAP binder. Before mixing, the rejuvenators were blended with fresh bitumen and the extracted and recovered RAP bitumen, and changes in the rheological properties of the binders were assessed using performance grading (PG) criteria. The results showed that both rejuvenators could improve the low-temperature performance of the aged RAP binder and restore its low-temperature properties. Master curves for the unaged, RTFO-aged, and PAV aged blends were constructed using both the Christensen-A…
