In this work we use the Parsimonious Multi–Asset Heston model recently developed in [Dimitroff et al., 2009] at Fraunhofer ITWM, Department Financial Mathematics, Kaiserslautern (Germany) and apply it to Quanto options. We give a summary of the model and its calibration scheme. A suitable...

Reference points influence economic decisions. This paper considers how health reference points and their adaptation to decreasing health influence medical spending, consumption, and investment in a dynamic model. A static reference point implies an aspiration to offset health losses already at...

We introduce a dynamic principal-agent model to understand the nature of contracts between an employer and an independent gig worker. We model the worker’s self-respect with an endogenous participation constraint; he accepts a job offer if and only if its utility is at least as large as his...

The occurrence and the transmission of large shocks in international equity markets is of essential interest to the study of market integration and financial crises. To this aim, implied market volatility allows to monitor ex-ante risk expectations in different markets. We investigate the...

This study's modeling analysis indicates that optimal hedging and optimal leverage decisions are patently different if undertaken jointly than when undertaken in isolation. The most striking result is that the optimal joint hedging and leverage strategy entails reduced hedging for a weak price...

We propose a novel framework for investigating learning dynamics on a competitive debt market. Observing a firm's survival of apparently distressed periods, the market eliminates asset value estimates that are too low to be consistent with the observed survival. Therefore, the firm's cost of...
