Modeling Industrial Dynamics with Innovative Entrants
The paper analyzes some generic features of industrial dynamics whereby innovative change is carried, stochastically, by new entrants. Relying on the formal representation suggested in Winter et al. (1997), it studies both the asymptotic properties of such processes and their finite dynamics to account for a few empirical stylized facts, including persistent entry and exit, skewed size distributions and turbulence in market shares
QED theory of the nuclear recoil effect on the atomic g factor
The quantum electrodynamic theory of the nuclear recoil effect on the atomic
g factor to all orders in \alpha Z and to first order in m/M is formulated. The
complete \alpha Z-dependence formula for the recoil correction to the
bound-electron g factor in a hydrogenlike atom is derived. This formula is used
to calculate the recoil correction to the bound-electron g factor in the order
(\alpha Z)^2 m/M for an arbitrary state of a hydrogenlike atom.Comment: 17 page
A Compact Beam Stop for a Rare Kaon Decay Experiment
We describe the development and testing of a novel beam stop for use in a
rare kaon decay experiment at the Brookhaven AGS. The beam stop is located
inside a dipole spectrometer magnet in close proximity to straw drift chambers
and intercepts a high-intensity neutral hadron beam. The design process,
involving both Monte Carlo simulations and beam tests of alternative beam-stop
shielding arrangements, had the goal of minimizing the leakage of particles
from the beam stop and the resulting hit rates in detectors, while preserving
maximum acceptance for events of interest. The beam tests consisted of
measurements of rates in drift chambers, scintilation counter hodoscopes, a gas
threshold Cherenkov counter, and a lead glass array. Measurements were also
made with a set of specialized detectors which were sensitive to low-energy
neutrons, photons, and charged particles. Comparisons are made between these
measurements and a detailed Monte Carlo simulation.Comment: 39 pages, 14 figures, submitted to Nuclear Instruments and Method
The Role of Organizational Competences in the Evolution of Business Models
International audienceThis paper presents the use of a conceptual framework designed for the management of organizational competences to contribute to the evolution of the business model of an enterprise. The framework, developed based on a detailed review of the history of the car manufacturer Toyota, was used for a Delphi study and an action-research applied in the furniture industry. The results suggest that it is applicable for ex-post analysis of organizational changes, as well as a strategy planning tool
Hiring New Key Inventors to Improve Firms’ Post-M&A Inventive Output
Although merger and acquisitions (M&As) are acknowledged as an important means to access innovative assets and know-how, firms’ inventive output often declines in the post-M&A period. Financial, managerial and organizational constraints related to the M&A event contribute to inventive output declines and inventors’ departure. Prior literature treats the acquiring firm as a passive observer of invention declines. This study argues that acquiring firms can take measures by hiring new key inventors. We show that the hiring of new key inventors in the post-M&A period can counteract invention declines in two ways. First, these newly hired inventors are associated with an increase of corporate inventive output after the M&A. Second, they are also associated with an improved inventive output of inventors already working for the acquiring firm. These results suggest that an appropriate hiring policy can counteract declining inventive output of firms in the aftermath of M&As
