FX smile in the Heston model
Janek, Agnieszka; Kluge, Tino; Weron, Rafał; Wystup, Uwe - 2010
The Heston model stands out from the class of stochastic volatility (SV) models mainly for two reasons. Firstly, the … process for the volatility is nonnegative and mean-reverting, which is what we observe in the markets. Secondly, there exists …

Investments in Gas Pipelines and Liquefied Natural Gas Infrastructure. What is the Impact on the Security of Supply?
Cayrade, Patrick - 2004
This paper addresses the question of the infrastructure investment required for gas pipeline and liquefied natural gas (LNG) connections to meet growing gas demand in an enlarged EU over the next 20 years. Several issues are presented, bearing in mind the major objective of the security of...

A diffusion approximation for the riskless profit under selling of discrete time call options: Non-identically distributed jumps
Nagaev, Alexander V.; Nagaev, Sergei A.; Kunst, Robert M. - 2005
A discrete time model of financial markets is considered. It is assumed that the relative jumps of the risky security price are independent non-identically distributed random variables. In the focus of attention is the expected non-risky profit of the investor that arises when the jumps of the...

Implied volatility of foreign exchange options: Is it worth tracking?
Gereben, Áron; Pintér, Klára - 2005
Market analysts and central banks often use the implied volatility of FX options as an indicator of expected exchange … deviate the value of implied volatility from the exchange rate variability expected by the market. These biasing factors are … one month. However, implied volatility provides a biased estimate, and does not encompass the information included in …

Who Creates Jobs? Estimating Job Creation Rates at the Firm Level
Huber, Peter; Oberhofer, Harald; Pfaffermayr, Michael - 2012
This paper shows that applying simple employment-weighted OLS estimation to Davis - Haltiwanger - Schuh (1996) firm level job creation rates taking the values 2 and -2 for entering and exiting firms, respectively, provides biased and inconsistent parameter estimates. Consequently, we argue that...

Robust estimation and inference in panels with interactive fixed effects
Armstrong, Timothy B.; Weidner, Martin; Zeleneev, Andrei - 2023
We consider estimation and inference for a regression coefficient in panels with interactive fixed effects (i.e., with a factor structure). We show that previously developed estimators and confidence intervals (CIs) might be heavily biased and size-distorted when some of the factors are weak. We...

Latin hypercube sampling with dependence and applications in finance
Packham, Natalie; Schmidt, Wolfgang M. - 2008
In Monte Carlo simulation, Latin hypercube sampling (LHS) [McKay et al. (1979)] is a well-known variance reduction technique for vectors of independent random variables. The method presented here, Latin hypercube sampling with dependence (LHSD), extends LHS to vectors of dependent random...

Sensitivities for Bermudan options by regression methods
Belomestny, Denis; Milstein, Grigori N.; Schoenmakers, … - 2007
In this article we propose several pathwise and finite difference based methods for calculating sensitivities of Bermudan options using regression methods and Monte Carlo simulation. These methods rely on conditional probabilistic representations which allow, in combination with a regression...

Deriving the term structure of banking crisis risk with a compound option approach: The case of Kazakhstan
Eichler, Stefan; Karmann, Alexander; Maltritz, Dominik - 2010
We use a compound option-based structural credit risk model to infer a term structure of banking crisis risk from market data on bank stocks in daily frequency. Considering debt service payments with different maturities this term structure assigns a separate estimator for short- and long-term...

Time Series Models with a Common Stochastic Variance for Analysing Economic Time Series
Koopman, Siem Jan; Bos, Charles S. - 2002
The linear Gaussian state space model for which the common variance istreated as a stochastic time-varying variable is considered for themodelling of economic time series. The focus of this paper is on thesimultaneous estimation of parameters related to the stochasticprocesses of the mean part...
