We propose a method for calibrating high-dimensional parameters in the Hull-White one-factor model using market prices of swaptions, aimed at generating mark-to-market interest rate scenarios in the Korean insurance industry. Our approach integrates a trust region-based Bayesian optimization...

This paper aims to develop optional semimartingale methods in risk theory to allow for a larger class of risk models. Optional semimartingales are left-continuous with right-limit stochastic processes defined on a probability space where the usual conditions - completeness and right-continuity...

The untapped potential of wave energy offers another alternative to diversifying renewable energy sources and addressing climate change by reducing CO2 emissions. However, development costs to mature the technology remain significant hurdles to adoption at scale and the technology often must...

Point forecasts of score-driven models have been shown to behave at par with those of state-space models under a variety of circumstances. We show, however, that density rather than point forecasts of plain-vanilla score-driven models substantially underperform their state-space counterparts in...

This paper proposes an alternative solution to the problem related to the risk that banks incur in the protection of deposits. This solution lies in the use by banks of contingent convertible leasing contracts to face financial distress situations by solidifying their own funds and thus...
