This paper deals with asymptotically efficient estimation in exchangeable nonlinear dynamicpanel models with common unobservable factor. These models are especially relevantfor applications to large portfolios of credits, corporate bonds, or life insurance contracts, andare recommended in the...

The main result of the paper is a formula for zero time-to-maturity limit ofimplied volatilities of European options under a broad class of stochastic volatilitymodels. Based on this formula, we propose a closed-form approximation of theimplied volatility smile.[...]

In this paper, we propose a model based on multivariate decomposition of multiplicative - absolute values and signs - components of several returns. In the m-variate case, the marginals for the m absolute values and the binary marginals for the m directions are linked through a 2m-dimensional...

We propose an affine term structure model which accommodates non-linearities in the drift and volatility function of the short-term interest rate. Such non-linearities are a consequence of discrete beta-distributed regime shifts constructed on multiple thresholds. We derive iterative closed form...

Risk management and asset pricing benefit from simple functional descriptions of the distribution of real asset returns. Recently, several authors have proposed that asset returns in real stock markets are distributed according to a hyperbolic distribution. While asset returns are generated by...

We study the real-time characteristics and drivers of jumps in option prices. To this end, we employ high frequency … data from the 24-hour E-mini S&P 500 options market. We find that option prices do not jump simultaneously across strikes … and maturities and are uncorrelated with jumps in the underlying futures price. 14% to 28% of detected option price jumps …

This paper offers an ambiguity-based interpretation of variance premium - the difference between risk-neutral and objective expectations of market return variance - as a compounding effect of both belief distortion and variance differential regarding the uncertain economic regimes. Our approach...
