Do Politically Motivated Import Bans Leave Lasting Scars? Evidence From Australian–Chinese Beef Trade

open access: yesAgribusiness, EarlyView.
ABSTRACT In May 2020, China abruptly suspended imports from several major Australian beef processors, escalating a diplomatic dispute between the two countries. This trade measure disrupted one of the largest beef export relationships in the world almost overnight.

Pesticide MRLs as Trade Barriers: Evidence From Vietnam's Coffee and Rice Exporters

open access: yesAgribusiness, EarlyView.
ABSTRACT As tariffs have declined globally through bilateral and regional trade agreements, food safety standards have emerged as significant determinants of agricultural trade flows. This study examines the impact of maximum residue limits (MRLs) for five pesticides—Azoxystrobin, Chlorpyrifos, Chlorantraniliprole, Clothianidin, and Cyhalothrin—on ...

Not All Agreements Are Equal: Heterogeneous Effects of RTAs on Latin American Agri‐Food Exports, 1990–2019

open access: yesAgribusiness, EarlyView.
ABSTRACT Since the final decade of the 20th century, Latin American countries have increasingly regarded the signing of regional trade agreements (RTAs) as a promising strategy for expanding their exports. Within this context, the main objective of this study is to assess the impact of RTAs on agri‐food exports in Latin America over the period 1990 ...

Dimensions of the AI Divide: Digital Inequality and Psychological Consequences

open access: yesAI &Innovation, EarlyView.
ABSTRACT Artificial intelligence (AI) has become a foundational component of contemporary social, economic, and political life. Yet, the ways in which AI reshapes patterns of exclusion beyond questions of access and technical capability remain insufficiently theorized.

Preferential trading in agriculture: New insights from a structural gravity analysis and machine learning

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Preferential trade agreements (PTAs) contain various non‐tariff provisions, yet identifying their trade effects remains challenging because these commitments are high‐dimensional and strongly correlated within agreements. We estimated a theory‐consistent structural gravity model with domestic flows for 26 agricultural subsectors over 1988–2017

Speckle Observations With PISCO in Calern (France): III. Astrometric Measurements of Visual Double Stars in 2019 and New or Revised Orbits for STT531 AB, STT77 AB, STF1338 AB, COU1746, STT260, A1109 AB, HU1291, and A632 AB

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT We present relative astrometric measurements of visual double stars, made in 2019 with the speckle camera PISCO at the 1‐m Epsilon telescope of the C2PU facility (Observatoire de la Côte d'Azur, Calern site). Our observing list contains orbital couples as well as double stars whose motion is still uncertain.

Revisiting Variable Stars Toward the Globular Cluster NGC 6496 With ATLAS and Gaia Photometry

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT We revisit 13 variable stars in the field of the metal‐rich globular cluster NGC 6496, discovered by Abbas et al. (2015; Astronomical Journal 149:40) (hereafter referred to as “MA15”) via time‐series data, spanning 2 years. We improve upon the MA15 characterization of the variables using ATLAS time‐series photometry data, spanning 8 years, in ...

Calculating Production Rate of each Branch of a Multilateral Well Using Multi-Segment Well Model: Field Example

open access: yesJournal of Engineering, 2017
Multilateral wells require a sophisticated type of well model to be applied in reservoir simulators to represent them. The model must be able to determine the flow rate of each fluid and the pressure throughout the well.
