We propose a novel time-changed L évy LIBOR market model for the joint pricing of caps and swaptions. The time changes are split into three components. The first component allows us to match the volatility term structure, the second generates stochastic volatility, and the third one...

We analyze the impact of funding costs and margin requirements on prices of index options traded on the CBOE. We propose a model that gives upper and lower bounds for option prices in the absence of arbitrage in an incomplete market with differential borrowing and lending rates. We show that...

This paper shows that the VIX market contains information on the variance of the S&P 500 returns, which is not already spanned by the S&P 500 market. We estimate a flexible affine model based on a joint time series of underlying indexes and option prices on both markets. We find that including...

Classical option pricing theories are usually built on the law of one price, neglecting the impact of market liquidity that may contribute to significant bid-ask spreads. Within the framework of conic finance, we develop a stochastic liquidity model, extending the discrete-time constant...

We analyze American put options in a hyper-exponential jump-diffusion model. Our contribution is threefold. Firstly, by following a maturity randomization approach, we solve the partial integro-differential equation and obtain a tight lower bound for the American option price. Secondly, our...

This paper introduces a novel firm-level green innovation measure utilizing ClimateBERT and GPT-3 models to analyze green patent abstracts and earnings call transcripts. Firms with higher green innovation measures experienced lower expected returns: a long-short portfolio generates an average...

This paper examines the impact of the EU Taxonomy's non-climate environmental criteria on the corporate credit risk term structure. We focus on infrastructure firm-level credit risk transmitted through CDS with differential maturities (e.g., ten-year minus one-year) in relation to biodiversity,...
