Global sustainability relies on our capacity of understanding and guiding urban systems and their metabolism adequately. It has been proposed that bigger and denser cities are more resource-efficient than smaller ones because they tend to demand less infra ...
In the Convex Body Chasing problem, we are given an initial point v0. Rd and an online sequence of n convex bodies F1,..., Fn. When we receive Ft, we are required to move inside Ft. Our goal is to minimize the total distance traveled. This fundamental onli ...
We model the financing, cash holdings, and hedging policies of a firm facing financing frictions and subject to permanent and transitory cash flow shocks. The permanent and transitory shocks generate distinct, sometimes opposite, effects on corporate polic ...
This thesis examines the effects of financing frictions on corporate decisions using dynamic models. Accounting for financing frictions helps reconcile a number of regularities that are hard to explain within the Modigliani-Miller framework. For instance, ...
This paper studies the potential gains of monetary and macro-prudential policies that lean against house-price and credit cycles. We rely on a model that features Borrowers and Savers and allows for over-borrowing induced by news-shock-driven cycles. We fi ...
Modelling of microturbulence-driven transport of energetic ions in an ITER steady-state scenario is presented. Results indicate that a significant fraction of the velocity space distribution of alpha particles and deuterium ions can be transported above ne ...
Studies on preferences for environmental quality usually posit that price and income explain most of the observed choices. However, we argue that conceptions of social norms and the common good are equally important when analyzing environmental voting outc ...
We prove that for any incomplete market and any concave utility function the marginal propensities to consume and to save are always positive. Furthermore, we intro- duce a class of incomplete markets that includes almost all well known examples of market ...
