I'm currently trying to estimate the market price of risk (lambda) in the Vasicek Model, and am running into difficulties. Using the Excel Solver tool and the Maximum Likelihood Estimation method for the other three parameters (mean, reversion speed, volatility) gave me good results but I'm having difficulties with the market price of risk.
Swap (CDS) when the hazard rate (or even of default) is modelled as the Vasicek-type model. The other objective is, by using South African credit spread data on defaultable bonds to estimate parameters on CIR and Vasicek-type Hazard rate models such as stochastic di erential equation models of term structure.
But im my research i have estimated these parameters by the GMM method and still only the market price of risk lamda to estimate by fitting the interest rate term structure of the vasicek model to the observed interest rate term structure. can you please tell me how can i do it. Models which are analyzed in this thesis are the well known Cox-Ingersoll-Ross one factor interest rate model and Vaˇsiˇcek interest rate model. They belong to the set of equilibrium models. These models generate predicted term structures whose shape depends on the models parameters and the initial short rate. Chapter 4 is focused on our goals. The paper is organized as follows: In section 2, we introduce model (1.1) under the Vasicek ASRF model framework, review the parameter estimation methodologies proposed in [27] for the multifactor Vasicek model (2.3), and show formulations (1.2) - (1.4).

This article develops an asymptotic theory for estimators of two parameters in the drift function in the fractional Vasicek model when a continuous record of observations is available. The fractional Vasicek model with long-range dependence is assumed to be driven by a fractional Brownian motion with the Hurst parameter greater than or equal to one half.

We find that when one allows for some degree of inhomogeneity in the probability of default (PD) across obligors, the correct estimate of the common correlation that should apply to each PD segment can differ significantly from the correlation estimated
Models can be roughly divided into equilibrium models and no-arbitrage models. Only equilibrium models are described here and from those only the Vasicek model used will be covered in greater detail. There are single or multifactor versions available of most models and the factors used vary but the first factor is usually the instantaneous interest

Vasicek model estimation. Since Vasicek first introduced his model of short term risk free interest rate the discussion of the parameters estimation continues. In this section we will discuss the most applied approaches following the literature on the relevant topics. Kimiaki Aonuma (1997) used Vasicek type model for Credit Default Swap valuation.

Keywords: maximum likelihood estimate; fractional Vasicek model; asymptotic distribution;. This paper is concerned about the problem of estimating the drift parameters in the fractional Vasicek model from a continuous record of observations. Based on Model 5 is the Ornstein-Uhlenbeck process used by Vasicek (1977) in deriving an equilibrium model of discount bond prices. Model 6 is the geometric Brownian Description. Estimates the parameters of the Vasicek model.
