Past Seminars

13 May 2010: 14:00-16:30 Sala degli Stemmi; Elena Fenili, Francesca Nenci, Angelica Attolico, Alessia Messina, Esra Gulfidan; (Unicredit - Political Studies Group)
Political Risk Assessment: In this seminar a team of analysts of the Unicredit Group Political Studies Research Unit will introduce the problem of assessment of political risk. After a general introduction the following topics will be covered:
- goals of the construction of a rating methodology for political risk
- how to analyze political risk and its impact in the operations of a large bank
- how to integrate different kinds of macroindicators
- construction of a rating and its evaluation in concrete examples

Title: Networks emerging in a volatile world: The paper proposes a stochastic dynamic model where agent behavior and the underlying social network coevolve in a setup with high link volatility, i.e. with connections subject to fast "obsolescence" and decay. Under these conditions, our objective is to understand whether, and how, a widely networked society may ever arise and then remain in place. A key feature of the model is that only agents displaying the same behavior form new links, while their common behavior remains in place as long as their link is maintained. This leads to a tight interplay between link creation and behavioral change in the dynamics of the system. The main contribution of the paper is three-fold. First, we find that, depending on the level of volatility, the model produces a wide range of possible behavior: sharp and gradual transitions, dense and sparse networks, or unique and multiple outcomes. Second, we show that this rich performance unfolds in a very different manner within different time horizons (e.g. concerning its reversibility or dependence on initial conditions). Third, we develop mathematical tools that integrate the analysis of these different horizons and also afford a full characterization of the predictions induced in each case.

Object construction in collective decisions: Economic models of decision making usually start with a problem of choice among exogenously given and “simple” alternatives. On the contrary, choice is often among objects that are constructed by individuals or institutions as complex bundles made up of many interdependent components. This pre-choice process of construction of the objects of choice is largely left unexplored in the literature. In the seminar I will present a model in which alternatives are bundles of interacting constituent elements and discuss how the power of constructing such objects can largely determine collective outcomes. Applications to social choice and to organizational decision making will be discussed.
