In this contribution we aim at improving ordinal variable selection in the context of causal models. In this regard, we propose an approach that provides a formal inferential tool to compare the explanatory power of each covariate, and, therefore, to select an effective model for classification...

We investigate competition for FDI within a region when a foreign multinational firm can profitably exploit differences in statutory corporate tax rates by shifting taxable profits to lower-tax jurisdictions. In such framework we show that targeted tax competition may lead to higher welfare for...

In this paper, we propose a novel Independent Factor Autoregressive Conditional Density (IFACD) model able to generate time-varying higher moments using an independent factor setup. Our proposed framework incorporates dynamic estimation of higher comovements and feasible portfolio representation...

Operational risk is hard to quantify, for the presence of heavy tailed loss distributions. Extreme value distributions, used in this context, are very sensitive to the data, and this is a problem in the presence of rare loss data. Self risk assessment questionnaires, if properly modelled, may...

This paper studies the effects generated by limited asset market participation under different fiscal and monetary policy games. We find that the distributional conflict due to limited asset market participation rises the inflation bias when the two authorities are independent and play...

We study information sharing in a Cournot duopoly with isoelastic demand function, when the elasticity is uncertain. This is one of the first attempts to analyze the role of nonlinearity in such a framework. We found important results about the profitability of sharing informations when marginal...

Bottazzi and Peri (2007) show that the existence of a cointegrating relationship between the domestic stock of knowledge, domestic R&D and the international knowledge stock can be interpreted as evidence supporting the semi-endogenous growth models versus the endogenous growth ones. We replicate...

In this paper we take in to considerations some classes of matrices which are generalizations of the class of K-matrices, in the terminology of Fielder and Ptàk (1962). We study the hierarchy and inclusion relations between the classes considered and we point out some economic applications

The financial world is basically divided in two: on one hand there are the experts, on the other hand the uninitiated. And, very often, it is a system that works: in very few (and very crazy) decided in fact to heal themselves, while the majority supports this division between secular and...

We study monopolistic competition with preferences over differentiated goods characterized by a separable indirect utility rather than a separable direct utility as in the Dixit-Stiglitz model, with the CES case as the only common ground. Examples include linear and log-linear direct demands. In...
