The Nelson-Siegel model is widely used in practice for fitting the term structure of interest rates. Due to the ease in linearizing the model, a grid search or an OLS approach using a fixed shape parameter are popular estimation procedures. The estimated parameters, however, have been reported...

The Nelson-Siegel and the Svensson models are widely used in practice for fitting the term structure of interest rates. However, due to their highly non-linear nature and the potential danger of multicollinearity, numerical difficulties in estimating these models hamper their implementation. In...

We estimate the long rate and its volatility within the Svensson framework. The procedure that best extrapolates the longest observable rate and its volatility is a 2-dimensional grid search conditioned on the ridge regression suggested by Annaert et al. (2013).

The Nelson–Siegel model is widely used in practice for fitting the term structure of interest rates. Due to the ease in linearizing the model, a grid search or an OLS approach using a fixed shape parameter are popular estimation procedures. The estimated grid search parameters, however, have...

This article estimates the achievement of Nobel Prize winners in Economics according to a simple model that exponentially relates fame to achievement. Based on Google hits, Paul Krugman, Joseph Stiglitz and Milton Friedman turn out to be the top-three economists that achieved the most. It is...
