Generalised Sharpe ratios and asset pricing in incomplete markets

A Černý - Review of Finance, 2003 - academic.oup.com
The paper presents an incomplete market pricing methodology generating asset price
bounds conditional on the absence of attractive investment opportunities in equilibrium. The …

[BOOK][B] Mathematical techniques in finance: tools for incomplete markets

A Cerný - 2009 - books.google.com
Originally published in 2003, Mathematical Techniques in Finance has become a standard
textbook for master's-level finance courses containing a significant quantitative element while …

An improved convolution algorithm for discretely sampled Asian options

A Černý, I Kyriakou - Quantitative Finance, 2011 - Taylor & Francis
We suggest an improved FFT pricing algorithm for discretely sampled Asian options with
general independently distributed returns in the underlying. Our work complements the studies …

On the structure of general mean-variance hedging strategies

A Černý, J Kallsen - 2007 - projecteuclid.org
We provide a new characterization of mean-variance hedging strategies in a general
semimartingale market. The key point is the introduction of a new probability measure P ⋆ which …

Hedging by sequential regressions revisited

A Černý, J Kallsen - Mathematical Finance: An International …, 2009 - Wiley Online Library
Almost 20 years ago Föllmer and Schweizer (1989) suggested a simple and influential
scheme for the computation of hedging strategies in an incomplete market. Their approach of …

Mean–variance hedging and optimal investment in Heston's model with correlation

A Černý, J Kallsen - Mathematical Finance: An International …, 2008 - Wiley Online Library
This paper solves the mean–variance hedging problem in Heston's model with a stochastic
opportunity set moving systematically with the volatility of stock returns. We allow for …

A unified approach to radial, hyperbolic, and directional efficiency measurement in data envelopment analysis

M Halická, M Trnovská, A Černý - European Journal of Operational …, 2024 - Elsevier
The paper analyses properties of a large class of “path-based” Data Envelopment Analysis
models through a unifying general scheme. The scheme includes the well-known oriented …

Introduction to fast Fourier transform in finance

A Černý - Research paper, 2006 - papers.ssrn.com
The Fourier transform is an important tool in Financial Economics. It delivers real time pricing
while allowing for a realistic structure of asset returns, taking into account excess kurtosis …

The theory of good-deal pricing in financial markets

A Černý, S Hodges - … —Bachelier Congress 2000: Selected Papers from …, 2002 - Springer
The term ‘no-good-deal pricing’ in this paper encompasses pricing techniques base on the
absence of attractive investment opportunities — good deals — in equilibrium. We borrowed …

Dynamic programming and mean‐variance hedging in discrete time

A Černý - Applied Mathematical Finance, 2004 - Taylor & Francis
In this paper the general discrete time mean‐variance hedging problem is solved by
dynamic programming. Thanks to its simple recursive structure the solution is well suited to …
