Job Market Seminars Giovanni Nicolò (UCLA)

"Monetary Policy, Expectations and Business Cycles in the U.S. Post-War Period" Job Market Paper Abstract This paper examines the interactions between monetary policy and the formation of expectations to explain U.S. business cycle fluctuations in the post-war period. I estimate a conventional medium-scale New-Keynesian model, in which I relax the assumption that the central pursued…

Saddlepoint techniques for dependent data Saddlepoint techniques provide numerically accurate, higher-order, small sample approximations to the distribution of estimators and test statistics. While a rich theory is available for saddlepoint techniques in the case of independently and identically distributed observations, only a few results have been obtained for dependent data. In this talk, we explain…

"Costly Verification in Collective decisions" Abstract We study how a principal should optimally choose between implementing a new policy and maintaining the status quo when the information relevant for the decision is privately held by agents. Agents are  strategic in revealing their information, but the principal can verify an agent's information at a given cost.…

Stochastic Differential Equations as Jets We explain how Ito Stochastic Differential Equations (SDEs) on manifolds may be defined using 2-jets of smooth functions. We show how this relationship can be interpreted in terms of a convergent numerical scheme. We show how jets can be used to derive graphical representations of Ito SDEs and how jets…

Seminars in Economics Francesco Sangiorgi (Frankfurt School)

"Why is capital slow moving? Liquidity hysteresis and the dynamics of limited arbitrage" Abstract Will arbitrage capital flow into a market experiencing a liquidity shock, mitigating the adverse effect of the shock on liquidity? Using a stochastic dynamic model of equilibrium pricing with privately informed capital-constrained arbitrageurs, we show that arbitrage capital may actually flow…

"Dynamics of Multiplex Networks in Schools" abstract Previous research has looked at the dynamics of social networks mainly in the context of friendship relations. In this seminar, the benefits of studying social network dynamics in multiplex dimensions are illustrated using social network panel data from Hungarian schools. By taking into account positive as well as…

Seminars in Politics and Society Sandro Cattacin (Université de Genève)

"Unexpected Inclusions: Migration, Mobility and the Open City" abstract Self-organisation of migrant association, independent civil society initiatives and established ritualised practices of inclusion in the city occur outside formal migration and integration policies and improve the dynamics of belonging and peaceful coexistence between the established and newcomers. Rather than crisis discourses, we are interested in routinised…
