The Ho and Lee model is the analogue for the study of the term structure of interest rates of the binomial tree introduced by Cox, Ross and Rubinstein in the one risky asset case. This model allows only for a small number of deformations of the term structure between two successive dates, and is...

Composite economic indicator is a very useful tool designed to trace and predict the business cycle conditions. In this paper we study possible extensions of this approach intended to cope with the potential data problems caused by various structural breaks affecting both level and volatility of...

The analysis and prediction of the short-run economic dynamics, or the evolution of the business cycle, often require a construction of the composite economic indicator (CEI). This indicator may be endowed with nonlinear dynamics to take care of the possible asymmetries between different phases...

We propose new closed-form pricing formulas for interest rate options which guarantee perfect compatibility with volatility smiles. These cap pricing formulas are computed under variance optimal measures in the framework of the market model or the Gaussian model and achieve an exact calibration...

In this paper we identify and try to predict the turning points of the Japanese business cycle. As a measure of the business cycle we use a composite economic indicator (CEI). This indicator is endowed with nonlinear dynamics to capture the asymmetries between different cyclical phases. Two...
