Estimating National and Foreign Trade Elasticities Using Generalized Transport Costs

open access: yesJournal of Regional Science, Volume 65, Issue 2, Page 471-496, March 2025.
ABSTRACT We introduce the definition of two distinct trade elasticities corresponding to imports from regions located in the same country (national elasticities) and foreign regions located in other countries (foreign elasticities). We resort to a three‐tier nested CES utility structure to derive the corresponding demand gravity equations.

Effects of soil moisture on microhabitat selection of two fossorial amphisbaenian reptiles from contrasting environments

open access: yesJournal of Zoology, EarlyView.
Extreme events expected under climate change (prolonged drought or torrential rains) alter soil conditions, yet their effects on fossorial vertebrates remain understudied. We tested substrate selection across moisture levels in two amphisbaenians from contrasting climates: Blanus cinereus (Iberian temperate forest) and Trogonophis wiegmanni (North ...

In an ever‐changing landscape, golden eagles in the Iberian Peninsula demonstrate remarkable dietary adaptability. We monitored 50 distinct breeding events over 4 years using camera traps, collecting over 520 000 images. Elevation, rather than land use, emerged as the main driver of prey composition: lagomorphs and columbiforms dominated at lower ...

Regulatory Approaches in the Face of a Pandemic: Assessing the Role of Ideology, Context, and Rule Design in Four Spanish Regions
