We consider interest rate models of Heath-Jarrow-Morton type where the forward rates are driven by a multidimensional Wiener process, and where the volatility structure is allowed to be a smooth functional of the present forward rate curve. In a recent paper (to appear in Mathematical Finance )...

This paper demonstrates how, without mechanically applying any formula like Nelson-Siegel or Nelson-Siegel-Svensson straight cut, a short term yield curve can intuitively be constructed with traded securities and then plugging the gaps with regression and cubic splines on case by case basis,...

I document a sizeable bias that might arise when valuing out of the money American options via the Least Square Method proposed by Longstaff and Schwartz (2001). The key point of this algorithm is the regression-based estimate of the continuation value of an American option. If this regression...

In this article we try to determine whether there is a relation between the quantity of athmospheric methane and the number of diseases of circulatory system, at the level of the whole country.We first analyze the time series of the quantity of pollutant between 1990 and 2008 and then we predict...

Determining the trend of fiscal pressure in Romania with analytical methods requires calculating the linear trend, the parabolic and the modified exponential one using the least square method. Then, with the help of absolute deviations between empirical and theoretical values will choose the...

The causality between the number of companies that are transacted in the Istanbul Stock Exchange market and economic growth in Turkish economy has been analyzed in this study. The analysis covers the 23 years between 1986 and 2009. The study shows that the number of new firms transacted in the...
