We propose a stable non-parametric algorithm for the calibration of pricing models for portfolio credit derivatives: given a set of observations of market spreads for CDO tranches, we construct a risk-neutral default intensity process for the portfolio underlying the CDO which matches these...

We provide a signal modality analysis to characterize and detect nonlinearity schemes in the US Industrial Production Index time series. The analysis is achieved by using the recently proposed 'delay vector variance ' (DVV) method, which examines local predictability of a signal in the phase...

In particular we show that: (1) as predicted by evolutionary theory, inventor productivity is a positive determinant of … invention value, (2) inter-firm mobility is a consistently positive determinant of productivity and (3) technological mobility …

Short-term increasing returns to production factors are usually found in empirical studies. We argue they can be due to omitted variables, particularly the intensity of factor utilisation. Thanks to original French firm-level data (1992-2008), we show how increasing returns to scale disappear...
