Assessing Basis Risk in Margin Insurance for Beef Cattle Farming in Brazil

Agricultural Economics, Volume 57, Issue 4, July 2026.
ABSTRACT Price volatility in agricultural markets directly affects the financial viability of rural producers, particularly in sectors characterized by narrow profit margins and long production cycles, such as beef cattle production. Futures contracts and agricultural insurance are commonly used to mitigate this risk; however, both instruments are ...

Can Technological and Customer Competencies Enable the Firm to Be Greener? Simultaneous Consideration of Resource‐Based View and Social License to Operate

Business Ethics, the Environment &Responsibility, Volume 35, Issue 3, Page 2480-2497, July 2026.
ABSTRACT This research explores the contribution of firm competencies and green management practices to enhancing a firm's sustainable performance. It examines the effects of technological competencies (TC) and customer competencies (CC) through the lens of a competence‐based view (CBV) framework, particularly focusing on their influence on green ...

Bayesian sequential design for Copula models: A comparison of designs selected under different Copula models

, 2017
Copula models provide flexible structures to derive the joint distribution of multivariate responses. However, they are rarely considered in the experimental design context, particularly in a Bayesian framework where model and parameter uncertainty are ...

Markov Determinantal Point Process for Dynamic Random Sets

Journal of Time Series Analysis, Volume 47, Issue 4, Page 784-802, July 2026.
ABSTRACT The Law of Determinantal Point Process (LDPP) is a flexible parametric family of distributions over random sets defined on a finite state space, or equivalently over multivariate binary variables. The aim of this paper is to introduce Markov processes of random sets within the LDPP framework. We show that, when the pairwise distribution of two

Testing Copula Hypothesis with Copula Entropy

Testing copula hypothesis is of fundamental importance in the applications of copula theory. In this paper we proposed a copula hypothesis testing with copula entropy. Since copula entropy is a unified theory in probability and therefore testing copula hypothesis based on it can be applied to any types of copula function.

Robust Bernoulli Mixture Models for Credit Portfolio Risk

Mathematical Finance, Volume 36, Issue 3, Page 528-543, July 2026.
ABSTRACT This paper presents comparison results and establishes risk bounds for credit portfolios within classes of Bernoulli mixture models, assuming conditionally independent defaults that are stochastically increasing in a common risk factor. We provide simple and interpretable conditions on conditional default probabilities that imply a comparison ...
