In this thesis, we derive an analytical closed-form approximation for European option prices under the GARCH diffusion model, where the price is driven by a geometric process and the variance by an uncorrelated mean reverting geometric process. This result has several important implications. First and foremost, these conditional moments allow us to obtain an analytical closed-form approximation...

The World Wide Web provides great opportunities for creating virtual classrooms of learners and instructors involved in distance education. Many software environments take advantage of the client-server communication on the Internet and support open and distance learning. Using environments called Course Management Systems (CMS), instructors can distribute information to students, produce content...

Elemento centrale della presente tesi é la comprensione dei fattori che guidano le imprese nelle scelte concernenti il trasferimento dei propri prodotti nello spazio e nel tempo. La motivazione alla base del lavoro é la convinzione che la modellizzazione del trasporto merci oggi non rifletta il comportamento effettivo delle imprese in modo soddisfacente. Una seconda motivazione della...

Corporate raiders are often associated with the 1980s takeover wave that reshaped the U.S. corporate landscape. While during the 1980s Europe remained relatively immune to this sort of investor, corporate raiders have operated actively both in Continental Europe and in the U.K. since the mid-1990s. Yet these corporate raiders are very different from the raiders that operated in the U.S. market...

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...

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...
