This paper incorporates an annual probability of corporate failure into a standard equity valuation model, as an alternative or complementary correction for risk that improves in several ways over conventional risk premia or ad hoc adjustments to assumed growth rates. Though the correction is nonlinear, it can be reduced to an equivalent function that enters the valuation equation in the tradit...

This paper studies the relationship between R&D, innovation and productivity in Dutch and French manufacturing using an unbalanced panel of enterprise data from three waves of the Community Innovation Survey pertaining to the period 1994-2004. We estimate by FIML a simultaneous-equation model of R&D, innovation and productivity accounting for individual effects and correcting for sample selecti...

We develop a rather simple, formally covariant quark-diquark model of the nucleon. The nucleon is treated as a bound state of a constituent quark and a diquark interacting via a quark exchange. We include both scalar and axial-vector diquarks. The underlying Bethe-Salpeter equation is transformed into a pair of coupled Salpeter equations. The electromagnetic form factors of the nucleon are calc...

Temperature and injection current dependence of electroluminescence (EL) spectral intensity of the super-bright InGaN single quantum well (SQW) light emitting diodes (LED’s) has been carefully investigated over a wide temperature range (T = 15-300 K) and as a function of injection current level (0.1-10 mA). It is found that, when T is decreased slightly to 140 K, the EL intensity efficiently in...

We study the problem of linear approximation of a signal using the parametric Gamma bases in L2 space. These bases have a time scale parameter which has the effect of modifying the relative angle between the signal and the projection space, thereby yielding an extra degree of freedom in the approximation. Gamma bases have a simple analog implementation which is a cascade of identical lowpass fi...

Innovation diffusion of network goods determines direct network externalities that exhibit delayed full benefits, depressing sales for long periods. We model a multiplicative dynamic market potential driven by a latent heterogeneous individual threshold derived from a basic economic theory by Economides and Himmelberg (1995) which is embedded in a special Cellular Automata representation. The c...
