Business Ethics, the Environment &Responsibility, EarlyView.ABSTRACT A common assumption is that firms become more socially responsible over time. Indeed, numerous conceptual papers focus on the issue of describing the CSR states that firms advance through. Yet, related empirical research remains limited and the assumption of steady progression across CSR states remains untested.

Small Sample Properties of Copula-GARCH Modelling: A Monte Carlo Study [PDF]
Copula-GARCH models have been recently proposed in the financial literature as a statistical tool to build flexible multivariate distributions. Our extensive simulation studies investigate the small sample properties of these models and examine how ...

LLM‐based prior elicitation for Bayesian graphical modeling
British Journal of Mathematical and Statistical Psychology, EarlyView.ABSTRACT In the Bayesian graphical modeling framework, priors on network structure encode theoretical assumptions and uncertainty about the topology of psychological constructs under study. For instance, the Bernoulli prior specifies the probability of each pairwise interaction, the Beta–Bernoulli prior governs expected network density, and the ...

Dynamic stochastic copula models: Estimation, inference and applications [PDF]
We propose a new dynamic copula model where the parameter characterizing dependence follows an autoregressive process. As this model class includes the Gaussian copula with stochastic correlation process, it can be viewed as a generalization of ...

To be or not to be? About the copula system in Buli (Gur) [PDF]
, 2008 This talk concerns the copula system in Buli, a Ghanaian language which has also been attested in Bahia (Rodrigues 1935, Zwernemann 1968). Special focus will be put on the categorization of two copula-reminiscent elements for which I will propose a ...

Creativity and Innovation Management, EarlyView.ABSTRACT While the literature on employees' innovative work behavior (IWB) treats leaders as a homogeneous source of firm‐internal knowledge, we examine how learning from different types of senior leaders (supervisors, coaches, and mentors) differentially affects employees' IWB and how these effects vary with the uncertainty of work tasks.

Copulas in finance and insurance [PDF]
Copulas provide a potential useful modeling tool to represent the dependence structure among variables and to generate joint distributions by combining given marginal distributions. Simulations play a relevant role in finance and insurance. They are used

Speculative Unity in Hegel's Restrictive Identity Claim
European Journal of Philosophy, EarlyView.Abstract Hegel identifies thought with the ‘in itself’ of things. It is common to read the statement as an unrestricted claim regarding Hegel's metaphysical view of reality. I argue it should be read as the expression of what speculative truth achieves.

Efficient estimation of parameters in marginals in semiparametric multivariate models [PDF]
Recent literature on semiparametric copula models focused on the situation when the marginals are specified nonparametrically and the copula function is given a parametric form.
