In this paper we compare market prices of credit default swaps with model prices. We show that a simple reduced form model with a constant recovery rate outperforms the market practice of directly comparing bonds' credit spreads to default swap premiums. We find that the model works well for...

We propose a new semi-parametric model for the implied volatility surface, which incorporates machine learning … implied volatility. To overcome the poor predicting power of existing models, we include a grid in the region of interest, and …

This study provides a case that the Thompson Waller estimator would have downward bias, which has not been carefully discussed in the literature. Such case is that (i) the buy (sell) order tends to follow buy (sell) order and (ii) the price change associated to such orders are small. The upward...
