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

Innovation and Knowledge Spillovers: Evidence from European Data [PDF]

open access: yes
This paper analyses the relative effects of national, international, sectoral and intersectoral spillovers on innovative activity in six large, industrialized countries (France, Germany, Italy, Japan, UK and US) over the period 1981-1995.

Elucidating Photo‐Kinetic Control in Photothermal Reverse Water‐Gas Shift Reaction

open access: yesAngewandte Chemie, EarlyView.
Light directly regulates the rate‐determining step (RDS) in photothermal catalysis. In a Mars–van Krevelen (MvK)‐type reverse water‐gas shift (RWGS) reaction over In‐doped MoO2, light shifts the RDS from the H2‐related reduction half‐reaction to the CO2‐related oxidation half‐reaction, enhancing catalytic activity and lowering the apparent activation ...

Farm labor scarcity and its uneven impacts on crop producers in the United States

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract This study is the first to evaluate the impacts of farm labor scarcity on producers in the United States across different crop production systems. Between 2002 and 2017, we disentangle the effects of labor scarcity from the impacts of rising commodity demand, technological change, and supply of other inputs on labor market outcomes.

INTERREGIONAL R&D SPILLOVERS IN EUROPE [PDF]

open access: yes
Our paper identifies and estimates the effects of R&D spillovers on total factor productivity with consideration of spatial effects. We first run our estimations on the Coe and Helpman (1995) model introducing spatial correlation.

Which Foreigners Are Worth Wooing? A Meta-Analysis of Vertical Spillovers from FDI [PDF]

open access: yes
The principal argument for subsidizing foreign investment is the assumed spillover of technology to local firms. Yet researchers report mixed results on spillovers.

Improving access to new technologies: An experiment with Kenyan input sellers

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Agrodealers play a critical role in rural economies, selling essential inputs for agricultural production, stocking new products, and providing farmers with technical advice. However, uncertainty can discourage them from stocking newer, less familiar products, limiting the availability of innovative technologies and leading to market failures ...

Decouple H2O2 Electrosynthesis From Microenvironmental Decomposition via Atomic Site Density Engineering

open access: yesAngewandte Chemie, EarlyView.
Using defect‐rich Co‐N2O2 single‐atom catalysts as a model system, this work reveals that atomic site density governs the competition between H2O2 electrosynthesis and microenvironmental decomposition during 2e−‐ORR. Optimised site isolation suppresses HPRR and HDR, thereby establishing a site‐density principle to balance H2O2 formation and ...

Channels of R&D Spillovers: An Empirical Investigation* [PDF]

open access: yes
R&D spillovers are, potentially, a major source of endogenous growth in various recent "new growthJ theory" models. The purpose of this paper is to investigate empirically the effectiveness of various channels of R&D spillovers.

Risk management externalities in agrifood supply chains

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Firms may under‐ or over‐invest in risk management from the social planner's perspective, resulting in a negative externality on other economic agents in the supply chain. The externality of risk management is particularly relevant for agrifood supply chains, which frequently experience disruptions and play a primary role in preventing major ...
