The finite-time ruin probabilities of a dependent bidimensional risk model with subexponential claims and Brownian perturbations

open access: yesNonlinear Analysis
The paper considers a dependent bidimensional risk model with stochastic return and Brownian perturbations in which the price processes of the investment portfolio of the two lines of business are two geometric Lévy processes, and the claim-number ...

Transport Resistance Dominates the Fill Factor Losses in Record Organic Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Organic photovoltaics are a promising solar cell technology, but even the record devices with 20% efficiency have significant fill factor losses due to low active layer conductivities. In this Perspective, the authors describe the origin of these losses, discuss experimental methods for their quantification, and explain how to minimize them to optimize

The future of dispute resolution in international trade

open access: yesApplied Economic Perspectives and Policy, EarlyView.
Abstract Given ongoing dysfunction of the World Trade Organization's Appellate Body, the focus of this article is on the future of trade dispute resolution, with evaluation of two questions: (i) What is the current status of WTO dispute resolution as compared to that conducted through existing preferential trade agreements (PTAs)? and (ii) What are the

Drivers of Farmers' Contract Compliance Behavior: Evidence From a Case Study of Dangote Tomato Processing Plant in Northern Nigeria

open access: yesAgribusiness, EarlyView.
ABSTRACT Contract farming is a viable strategy agribusinesses rely on to strengthen coordination across actors in the value chain. However, low contract compliance remains a significant setback to agribusinesses' contract performance in low‐ and middle‐income country context.

Access to Finance and Innovation in the Canadian Food Processing

open access: yesAgribusiness, EarlyView.
ABSTRACT Innovation is a presumed channel through which finance affects productivity, yet there is limited research testing the relationship between finance and innovation in the food manufacturing sector. The purpose of the paper is to explore the determinants (e.g., financing, R&D, firm size, expenditure on innovation) of the adoption of innovation ...

A Refined Dual‐Fiber Network Morphology as Printable Hole Transport Layers for High‐Performance Perovskite Solar Mini‐Modules

open access: yesAggregate, EarlyView.
To address the problems of uneven printing of the hole transport layers (HTLs) and the instability of the device due to the HTLs, we propose a dual‐fiber network structure (DFNS) strategy based on polymer HTLs. This strategy involves the spontaneous interweaving of micron‐sized fiber crystals to create efficient carrier transport channels.
