The Harvard community has made this article openly available. Please share how this access benefits you. Your story matters. This paper attempts to provide microfoundations for the knowledge production function in an idea-based growth model. Production of new ideas is made a function of newly reconfigured old ideas in the spirit of the way an agricultural research station develops improved plan...
متن کاملEndogenous Recombinant Growth
We extend Weitzman’s (1998) recombinant growth framework to include endogenous R&D decisions. The analysis is carried out in the (knowledgecapital) state space by means of two characteristic curves: one is identified as a turnpike along which growing economies evolve; the other attracts stagnating economies. Sustained growth depends on a condition relating the slopes of the characteristic curve...
متن کاملEndogenous Recombinant Growth and Intellectual Property Rights
We show that, even in a framework in which monopolistic exploitation of patents does not occur, patents still give rise to serious drawbacks. We build on Weitzman’s (1998) recombinant growth model which provides a stylized but clear description of the formation of knowledge externalities. In our framework a benevolent government buys immediately new patents in a competitive market and releases ...
متن کاملTherapeutic Effects of Recombinant Growth Hormone in Improving the Growth of Thalassemia Major Patients: A Retrospective Study
Background and purpose: Beta thalassemia major is one of the most common inherited blood diseases and patients with this condition require regular blood transfusions. The resulting iron overload deposition causes endocrine gland disorders, including growth hormone (GH) abnormality. In this study, we examined the effects of recombinant growth hormone (rGH) in these patients. Materials and metho...
متن کاملPapillary Carcinoma of Thyroid Gland in a Patient Treated with Recombinant Growth Hormone
The first successful treatment of growth hormone (GH) deficient children with GH extracted from human pituitary was introduced during late 1950's. The subsequent availability and use of recombinant GH (rhGH) for different clinical conditions raised the question of whether this new therapeutic modality increases the risk of certain conditions such as leukemia or malignancy. Herein, we report o...
