This paper exploits the formalization of a circular product differentiation model of Salop (1979) to propose an endogenous growth quality ladder model in which the knowledge inherent in a given sector can spread variously across the sectors of the economy, ranging from local to global influence. Accordingly, this affects the size of the pool of knowledge in which innovations draw themselves on in order to be produced. Therefore, the law of knowledge accumulation, and thus the growth rate of the economy, depend positively on the expected scope of diffusion of innovations, i.e. on the intensity of knowledge spillovers. This approach generalizes the endogenous growth theory as developed in the seminal models of Grossman & Helpman (1991) and Aghion & Howitt (1992), extending their analysis to the possibility of considering stochastic and partial knowledge spillovers. This framework allows us to mitigate the positive e xternality of knowledge and thus to apprehend the issue of the funding of research with more parsimony. We characterize the set of steady-state Schumpeterian equilibria as a function of the public tools. We provide an explanation for the fact that research effort can either be suboptimal or over-optimal, depending on the expected scope of knowledge. Accordingly, we find that the optimal public tool dedicated to foster R&D activity depends positively on it.
Keywords: Schumpeterian growth, scope of diffusion of innovations, knowledge spillovers

  • The co-evolution of organizational value capture, value creation and sustainable advantage

Despite recent emphasis on intra-organizational issues, scholarship on organizations, management and strategy remains unduly reliant on economic models, such as the industrial organization (IO) market structure-based analysis. The focus of such models is on price-output determination by firms and the economy-wide efficient allocation of scarce resources under conditions of full knowledge and certainty. This limits their usefulness for students of organizations who have concerns that are simultaneously wider and also focused on organizations, as opposed to just markets. In this paper, we aim to provide an answer and framework for analysing the most fundamental, indeed existential, issue of organization studies and strategic management scholarship. This is whether and how the pursuit of value capture from economic agents who perceive that they possess appropriable value creating advantages, capabilities and action potential , can motivate the emergence of organizations and their strategies and actions intended to capture socially co-created value in conditions of real life . To do so, we explore (the co-evolution of) value capture and creation and (their relationship to) organizational sustainable advantage (SA). In particular, we delve into the nature, determinants and relationship between organizational value capture and creation and explore causal pathways, trade-offs and their co-evolution, as well as vehicles through which SA can be effected in an evolving and uncertain environment. We also discuss implications for managerial practice, limitations and future research opportunities.

  • Costly Investment, Complementarities, International Technological-Knowledge Diffusion and the Skill Premium

We examine the behavior of the skill premium in a two-country general equilibrium growth model assuming (i) technological-knowledge diffusion; (ii) internal costly investment in both physical capital and R&D; and (iii) complementarities between intermediate goods in production. We find that these three economic features affect the steady-state growth rate in both countries. However, only in the imitator country do they influence the skill premium. We also find that the steady-state skill premium in the innovator country is affected by its relative labor productivity rather than by its relative labor endowments. This result contrasts with most skill-biased technological change models and suggests that the sustained increase in the skill premium observed in several developed countries over the last three decades may have been due to increases in the relative productive advantage of skilled labor.
Keywords: technological-knowledge bias, skill premium, complementarities, costly investment, technological-knowledge diffusion

This paper aims to investigate the effect of knowledge characteristics on the total factor productivity of firms developing drugs in the pharmaceutical industry. We decompose knowledge into knowledge associated with the technological firm portfolio and knowledge related to R&D projects, which represent drug development at the clinical testing stage. The latter is attributed to the knowledge of relevant markets where the drugs will be sold. The results show that the effect of technological coherence vs. market coherence and of accumulated knowledge on the productivity of firms differs. Productivity increases with the number of patents and decreases with the patent diversity and project portfolio coherence. When considering only the project knowledge, the diversity of the project portfolio positively affects productivity.
Keywords: total factor productivity, diversity,,coherence, knowledge
