In recent years numerous studies have been published highlighting the role of financial structures in the development process of contemporary economies.1 These works represent a break with a widely-held theoretical view holding that income, wealth and economic growth are independent of the...

Peskun ordering is a partial ordering defined on the space of transition matrices of discrete time Markov chains. If the Markov chains are reversible with respect to a common stationary distribution "greek Pi", Peskun ordering implies an ordering on the asymptotic variances of the resulting...

Herbert A. Simon is widely known for his studies on rationality, artificial intelligence and for his pioneering approach to organizational studies. In one of his latest works, he presented a theory of human interaction, focused on the conflict between the selfish and the altruistic that can be...

This paper applies a new spatial approach for the specfication of multivariate GARCH models, called Spatial Effects in ARCH, SEARCH. We consider spatial dependence associated with industrial sectors and capitalization size. This parametrization extends current feasible specifications for large...

The environmental and social responsibility “movements” affected jointly corporate behavior and public policy in many countries, while their theoretical backgrounds have resulted often quite different and independent. Despite this divide, we argue that the two approaches share many elements...

In the present paper we study the stability of a threshold continuos-time model that belongs to the class of Piecewise Deterministic Markov Processes. We derive a sufficient condition on the coefficients of the model to ensure the exponential ergodicity of the process under two different...

In the present paper we study the stability of a class of nonlinear ARMA models. We derive a sufficient condition to ensure the geometric ergodicity and we apply it to a very general threshold ARMA model imposing a mild assumption on the thresholds

The way Simon, and the major part of the scholars, presented and used bounded rationality directly refers to human computational capabilities (or “brute-force”). Despite its broad powers of explanation, some problems arise when taking into account the way the human cognitive system really...

The task of comparing two random vectors with respect to some multivariate stochastic ordering usually involves an infinite number of comparisons. Dyckerhoff and Mosler (1997) proved that, when the random vectors have finite supports, this task, for some orderings, can be simplified by...

In vector optimization many notions of approximate solution have been proposed in the literature. In this paper an axiomatic approach is introduced in order to study the approximate solution map of a vector optimization problem in the image space. An impossibility result is proved in the sense...
