this paper using endogenous growth models based on research and development, has investigated two economic relations in three groups of countries included developed countries, developing countries and a mixed group of both mentioned ones. at first, the effects of r&d; activities on patent growth have examined and then the relation between volume of patent and growth rate in these groups has sur...

We study a model of technology adoption. The firm’s profit is depending on the technology that it uses. The firm holds the option to upgrade its current technology with a new one. Technology progress is modeled with a Poisson process. The firm can either rely on the external R&D market or it can setup its own R&D center. The arrival rate of new technologies in the external R&D market is constan...

We use a duopoly to show how the possibility of licensing ex post R&D affects the decision on R&D organization. We show that whether licensing ex post R&D affects the incentive for doing cooperative R&D depends on the nature of cooperative R&D. If the firms do cooperative R&D to avoid duplication in R&D process then the possibility of licensing ex post R&D may influence the decision on R&D orga...

The relationships between basic and applied agricultural R&D, developed and developing country R&D and between R&D, extension, technology and productivity growth are outlined. The declining growth rates of public R&D expenditures are related to output growth and crop yields, where growth rates have also fallen, especially in the developed countries. However, growth in output value per hectare h...

Systems factorial technology (SFT) comprises a set of powerful nonparametric models and measures, together with a theory-driven experiment methodology termed the double factorial paradigm (DFP), for assessing the cognitive information-processing mechanisms supporting the processing of multiple sources of information in a given task (Townsend and Nozawa, Journal of Mathematical Psychology 39:321...

development of technological capability is one of the effective methods for promoting the firm competitive performance. transfer of suitable technology help the firm to make a strong position in its industry faster than using in-house r&d.; successfulness of a firm based on technology transfer process can be measured with different scales such as measurement of firm competitive performance thro...
