In a complete financial market every contingent claim can be hedged perfectly. In an incomplete market it is possible to stay on the safe side by superhedging. But such strategies may require a large amount of initial capital. Here we study the question what an investor can do who is unwilling...

An investor faced with a contingent claim may eliminate risk by (super-)hedging in a financial market. As this is often quite expensive, we study partial hedges, which require less capital and reduce the risk. In a previous paper we determined quantile hedges which succeed with maximal...

This paper is the first to analyze and value early exercises of Individual Investors in fixed-income investment products. Assuming decision and transaction costs we consider that a continuous decision-making on holding or exercising is not optimal anymore and propose a new approach to modeling...

A small but ambitious literature uses affine arbitrage-free models to estimate jointly U.S. Treasury term premiums and the term structure of equity risk premiums. Within this approach, this paper identifies the parameter restrictions that are consistent with a simple dividend discount model,...

Does the selection of a specific interest rate model to use for pricing, hedging, and risk-return analysis depend upon whether the user is a buy-side institution or a sell-side dealer bank? Sanjay Nawalkha and Riccardo Rebonato debate this question in this paper and provide some insightful...

We contrast two different asset pricing models, where the pricing kernel either (i) increases in the volatility dimension, reflecting investors' aversion to volatility, or (ii) could be non-monotonic in volatility, reflecting heterogeneity in investors' beliefs. The two models yield opposite...

People by and large tend to postpone their present consumption for numerous reasons. This postponement of consumption leaves them with surplus money to invest for future consumption. Amongst the number of alternatives avenues present for such investments, gold too tends to be one of them. People...

This paper estimates how the shape of the implied volatility smile and the size of the variance risk premium relate to parameters of GARCH-type time-series models measuring how conditional volatility responds to return shocks. Markets in which return shocks lead to large increases in conditional...

Skewness is specifically considered to develop semi-parametric upper bounds for option prices and expected payoffs for call options. Bounds on variance default swaps, a new asset, and for the variance risk premium are derived.The Technical Proof for this paper is available at the following URL:...

This paper studies the predictability of S&P500 returns using short term risk premia as a conditioning variable. We construct dividend prices using futures data and identify short term risk premia by projecting excess returns of dividend claims on their lagged prices. Regression results for...
