We present high-cycle aging tests of Dielectric Elastomer Actuators (DEAs) based on silicone elastomers, reporting on the time-evolution of actuation strain and of electrode resistance over millions of cycles. We compare several types of carbon-based elect ...

Over and over again, history shows that countries default on external debt when their economies experience a downturn. This paper presents a theoretical model of international lending that is consistent with this evidence. Productivity is stochastic and in ...
We solve the problem of optimal risk management for an investor holding an illiquid, alpha-generating fund and hedging his/her position with a liquid futures contract. When the investor is subject to a lower bound on net return, he/she is forced to reduce ...
lexible electronic devices are currently being developed using polymer substrates. Such devices present advantages like conformability, are light-weight and are expected to be manufactured in roll-to-roll (R2R) schemes accounting for cost-reduction. These ...

This thesis develops models for three problems of liquidity under asymmetric information.
In the chapter "Disclosures, Rollover Risk, and Debt Runs" I build a model of dynamic debt
runs without perfect information in order to understand the impact of asset ...
Due to its enormous size and capital base, the insurance industry has the potential to play a key role in countering climate change. To this end, the major capital flows associated with its investment and underwriting businesses would need to be redirected ...
We contribute to the ongoing debate on the differential effects of two important intangible assets on organizational outcomes: reputation and status. We explore whether they exert distinct signaling effects on external parties whom evaluate the quality of ...
Dissipative solitons are self-localized structures resulting from a double balance between dispersion and nonlinearity as well as dissipation and a driving force. They occur in a wide variety of fields ranging from optics, hydrodynamics to chemistry and bi ...
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, ...
