We estimate inflation risk-neutral densities (RNDs) in the Euro area since 2009. We use Euro inflation swaps and caps/floors options, and introduce a simple and parsimonious approach to jointly estimate the RNDs across horizons. This way, we obtain the implicit RND for forward measures, like the...

The value of American options depends on the exercise policy followed by option holders. Market frictions, risk aversion, a misspecified model, or an inaccurate algorithm can result in suboptimal behavior. We study the sensitivity of American options to suboptimal exercise strategies. We show...

Least-squares methods enable us to price Bermudan-style options by Monte Carlo simulation. They are based on estimating the option continuation value by least squares. We show that the Bermudan price is maximized when this continuation value is estimated near the exercise boundary, which is...

This paper addresses the hedging of bond portfolios interest rate risk by drawing on the classical one period no-arbitrage approach of Financial Economics (Ingersoll (1987)). Under quite weak assumptions on the interest rate behavior several shadow riskless assets are introduced by means of...

Consider a non-spanned security C_{T} in an incomplete market. We study the risk/return trade-offs generated if this security is sold for an arbitrage-free price Câ‚€ and then hedged. We consider recursive "one-period optimal" self-financing hedging strategies, a simple but tractable...

In a default corridor [0; B] that the stock price can never enter, a deep out-of-the-money American put option replicates a pure credit contract (Carr and Wu, 2011). Assuming discrete (one-period-ahead predictable) cash áows, we show that an endogenous credit-risk model generates, along with the...

Although Bermudan options are routinely priced by simulation and least-squares methods using lower and dual upper bounds, the latter are hardly optimized. In this paper, we optimize recursive upper bounds, which are more tractable than the original/nonrecursive ones, and derive two new results:...
