We provide benchmarks to evaluate what is an optimal foreign debt and a maximal foreign debt (debt-max), when risk is explicitly considered. When the actual debt exceeds debt-max, then the economy will default when a bad shock occurs. This paper is an application of the stochastic optimal...

We provide benchmarks to evaluate what is an optimal foreign debt and a maximal foreign debt (debt-max), when risk is explicitly considered. When the actual debt exceeds debt-max, then the economy will default when a "bad shock" occurs. This paper is an application of the stochastic optimal...

La costruzione di un controesempio aritmetico coerente con gli assiomi di Zermelo e Fraenkel che contraddice l’equivalenza della doppia negazione relega l’equivalenza della doppia negazione al sistema logico elementare classico della certezza e la esclude dai sistemi simbolici formalizzati...

It is impossible to prove the equivalence of double negation for the Systeme I of Godel. It is possible to deduce the equivalence of double negation with a three valued logic which is coherent with respect to symmetric implication and has the third value as invariant by negation. It is possible...

This paper derives the implications for migrants’ self-selection in unobservables that arise from the introduction of uncertainty in the decision problem that would-be migrants face. We show that if one lifts the assumption introduced in Borjas (1987) that foreign wages are known before the...

In questo paper sono esaminate e discusse criticamente le giustificazioni addotte dalle letteratura a sostegno di un saggio di preferenza temporale sia a livello dell’allocazione ottima di capitale che dell’equità fra diverse generazioni. Dopo una breve disamina storica relativa alle...
