Structural simulation in international trade = Simulazione strutturale nel commercio internazionale

Ramírez, Vicente ; Tonella, Giorgio (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2002 ; 2002ECO001.

This thesis explores a way of representing the structure of the international trade system and of understanding its behaviour. Its main contribution is a model, developed following computer simulation methodology, that deals with interactions and interdependencies in international trade, and consequently, with the study of patterns of trade and trading bloc formation. The simulation model allows...

Robust statistical procedures for location and scale dynamic models with applications to risk management

Mancini, Loriano ; Ronchetti, Elvezio (Dir.) ; Trojani, Fabio (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2004 ; 2004ECO001.

In the first part of the thesis, we study the local robustness of inference procedures of the conditional location and scale parameters in a stationary time series model. We first derive optimal bounded-influence estimators for the parameters of conditional location and scale models under a conditionally Gaussian reference model. Based on these results, optimal bounded-influence versions of the...
