In this paper we assess the evolution of employment and wage inequality in Europe and the US labour markets over the past two decades. We find that the salient trends in wage structures are more complicated than implied ...

The class of Multivariate BiLinear GARCH (MBL-GARCH) models is proposed and its statistical properties are investigated. The model can be regarded as a generalization to a multivariate setting of the univariate BLGARCH model ...

Da oltre un ventennio la ricerca universitaria è decisamente uscita dalla tradizionale “torre d’avorio” e le collaborazioni di ricerca con l’industria e la tutela della proprietà intellettuale sui risultati della ricerca ...

Historically, economists have, whenever possible, used linear equations to model economic phenomena, because they are easy to manipulate and usually yield unique solutions. However, it now has become impossible to ignore ...

Si `e pi `u volte osservato in letteratura come gli approcci non parametrici alla stima della frontiera di produzione siano scarsamente robusti rispetto alla presenza di valori eccezionali. Il presente lavoro propone una ...

Grahn, (1995) introduced the Conditional Least Squares estimators for the class (I) of bilinear models. Such estimators have a variance which is difficulty to derive analytically. The aim of the present paper is to consider ...

Today tourism represents one of the most dynamic economic sectors in the world. Even if the majority of international tourism still takes place within the developed world, recently tourism to developing countries is becoming ...

In this note we consider some notions of well-posedness for scalar and vector variational inequalities and we recall their connections with optimization problems. Subsequently, we investigate similar connections between ...
