This essay studies the optimal timing for a firm to adopt a new process innovation in the presence of learning. A policy that has been implemented by governments throughout the world to reduce the cost level of infant industries with positive externalities, is to either subsidize the research of these technologies or their distribution. This model demonstrates how government interventions can a...
متن کاملThe parameter-free track structure model of Scholz and Kraft for heavy-ion cross sections.
The "parameter-free", "local effects" theory of Scholz and Kraft is an extension to mammalian cells of the theory of RBE for dry enzymes and viruses of Butts and Katz. Its claim for parameter freedom has been challenged elsewhere. Here we examine its conceptual base and find errors in its use of the physical concept of cross section and its neglect of the radiobiological relationship between ta...
متن کاملRay Rees; Sebastian Scholz: Optimal Fertility Decisions in a Life Cycle Model
This model is the first to solve for the optimal timing of childbirth and number of children in a continuous time framework simultaneously. The model depicts how changes in wage at different stages of an individual’s life influence the timing decision of childbirth and the optimal number of children. When a woman wants to have more children, she decides to have them at a younger age. Medical re...
متن کاملNeuronal activity in early visual areas during global and local processing: a comment on Heinze, Hinrichs, Scholz, Burchert and Mangun.
In a paper published in the 10:4 issue of JOCN, Heinze et al. 1998) studied a directed attention task using hierarchically organized letter Navon stimuli. On the basis of negative PET and ERP findings, they argue that``early sensory inputs are not modulated to gate global vs. local visual information differentially into the two hemispheres .'' Rather, based on positive ERP findings (an N2 effec...
متن کاملLipid Metabolism by Rat Lung in vitro EFFECT OF STARVATION AND RE-FEEDING ON UTILIZATION OF [U-14C]GLUCOSE BY LUNG SLICES BY RICHARD W. SCHOLZ
1. The incorporation of [U-14C]glucose into several lipid components of lung and liver slices, and the activities of glucose 6-phosphate dehydrogenase (EC 1.1.1.49), 6-phosphogluconate dehydrogenase (EC 1.1.1.44), 'malic' enzyme (EC 1.1.1.40) and NADP-isocitrate dehydrogenase (EC 1.1. 1.42) of the cell cytosol were examined in normal, starved and re-fed rats. 2. Lipogenesis and the activities o...
