However, in the\u0000current state-of-the-art, Monte Carlo simulations of these processes are not\u0000straightforward for two main reasons: i) algorithms are available only for some\u0000particular processes within this class; ii) they are often computationally\u0000expensive. In this paper, we introduce a new simulation technique designed to\u0000address both challenges. It relies on the numerical inversion of the\u0000characteristic function, offering a general methodology applicable to all\u0000L'evy-driven OU processes. Moreover, leveraging FFT, the proposed methodology\u0000ensures fast and accurate simulations, providing a solid basis for the\u0000widespread adoption of these processes in the energy sector. Lastly, the\u0000algorithm allows an optimal control of the numerical error. We apply the\u0000technique to the pricing of energy derivatives, comparing the results with\u0000existing benchmarks. Our findings indicate that the proposed methodology is at\u0000least one order of magnitude faster than existing algorithms, all while\u0000maintaining an equivalent level of accuracy.","PeriodicalId":501355,"journal":{"name":"arXiv - QuantFin - Pricing of Securities","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139587900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein F is the ``public\" flow of information which is\u0000available to all agents overtime, S is the discounted price process of\u0000d-tradable assets, and T is an arbitrary random time whose occurrence might not\u0000be observable via F. Thus, we consider the larger flow G which incorporates F\u0000and makes T an observable random time. This framework covers the credit risk\u0000theory setting, the life insurance setting and the setting of employee stock\u0000option valuation. For the stopped model (S^T,G) and for various vulnerable\u0000claims, based on this model, we address the super-hedging pricing valuation\u0000problem and its intrinsic Immediate-Profit arbitrage (IP hereafter for short).\u0000Our first main contribution lies in singling out the impact of change of prior\u0000and/or information on conditional essential supremum, which is a vital tool in\u0000super-hedging pricing. The second main contribution consists of describing as\u0000explicit as possible how the set of super-hedging prices expands under the\u0000stochasticity of T and its risks, and we address the IP arbitrage for (S^T,G)\u0000as well. The third main contribution resides in elaborating as explicit as\u0000possible pricing formulas for vulnerable claims, and singling out the various\u0000informational risks in the prices' dynamics.","PeriodicalId":501355,"journal":{"name":"arXiv - QuantFin - Pricing of Securities","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139459693","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

No, rough\u0000volatility models are inconsistent with the global shape of SPX smiles. They\u0000suffer from severe structural limitations imposed by the roughness component,\u0000with the Hurst parameter $H in (0,1/2)$ controlling the smile in a poor way.\u0000In particular, the SPX at-the-money skew is incompatible with the power-law\u0000shape generated by rough volatility models. The skew of rough volatility models\u0000increases too fast on the short end, and decays too slow on the longer end\u0000where \"negative\" $H$ is sometimes needed.

{"title":"A framework for the valuation of insurance liabilities by production cost","authors":"Christoph Moehr","doi":"arxiv-2401.00263","DOIUrl":"https://doi.org/arxiv-2401.00263","url":null,"abstract":"This paper sets out a framework for the valuation of insurance liabilities\u0000that is intended to be economically realistic, elementary, reasonably\u0000practically applicable, and as a special case to provide a basis for the\u0000valuation in regulatory solvency systems such as Solvency II and the SST. The\u0000valuation framework is based on the cost of producing the liabilities to an\u0000insurance company that is subject to solvency regulation (regulatory solvency\u0000capital requirements) and insolvency laws (consequences of failure) in finite\u0000discrete time. Starting from the replication approach of classical no-arbitrage\u0000theory, the framework additionally considers the nature and cost of capital\u0000(expressed by a ``financiability condition\"), that the liabilities may be\u0000required to be fulfilled only ``in sufficiently many cases\" (expressed by a\u0000``fulfillment condition\"), production using ``fully illiquid\" assets in\u0000addition to tradables, and the asymmetry between assets and liabilities. We\u0000identify necessary and sufficient conditions on the capital investment under\u0000which the framework recovers the market prices of tradables, investigate\u0000extending production to take account of insolvency, implications of using\u0000illiquid assets in the production, and show how Solvency II and SST valuation\u0000can be derived with specific assumptions.","PeriodicalId":501355,"journal":{"name":"arXiv - QuantFin - Pricing of Securities","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139077878","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
