The paper proposes a new class of continuous-time asset pricing models where negative jumps play a crucial role. Whenever there is a negative jump in asset returns, it is simultaneously passed on to diffusion variance and the jump intensity, generating self-exciting co-jumps of prices and...

I provide a simple example of a single peaked utility function that generates a Giffen demand. The utility function is smooth, non piecewise defined, strictly concave but not globally increasing. A full characterization of the parameter conditions under which the Giffen demand arises is...

We apply the Optimal Classification method to a newly created dataset to provide a spatial map of the Italian Second Republic (1996-2008). We find a bi-dimensional political space in the XIII Legislature and virtually a one dimensional political space in the XIV and XV Legislatures. In addition,...

We develop a tractable model of competition among motivated MFIs. We find that equilibria may or may not involve double-dipping (and consequently default), with there being double-dipping whenever the MFIs are very profit-oriented. Moreover, in an equilibrium with double-dipping, borrowers who...

Recent literature has proposed two alternative types of financial frictions, i.e., limited commitment and incomplete markets, to explain the patterns of international capital flows between developed and developing countries observed in the past two decades. This paper integrates both types of...

We simulate the impact of actual food price increase between June 2006 and June 2008 on poverty across different areas and whether the household’s main income source is agricultural activities. We explicitly treat heterogeneity in food price changes and the patterns of consumption and...

We extend the Arrow-Fisher-Hanemann-Henry (AFHH) and Dixit-Pindyck (DP) option values to game situations. By reinterpreting the AFHH option value as a change in the surplus from conservation because of the prospect of future information, we deal with the conceptual difficulty associated with the...

This paper studies a life-cycle model of home production to examine how married women change their allocation of time in response to evolutionary movements along the life-cycle wage profile in Japan. After accounting for the potential bias due to heterogeneity, measurement error, weak...

This paper investigates the impact of social-network based political connections on firm value. We focus on the networks of university classmates and alumni among directors of U.S. public firms and congressmen. Comparing firms connected to elected versus defeated politicians in the Regression...

We show that isolated capital cities are robustly associated with greater levels of corruption across US states. In particular, this is the case when we use the variation induced by the exogenous location of a state’s centroid to instrument for the concentration of population around the...
