This paper presents a closed economy model of endogenous growth driven by capital externalities arising from both private capital and public infrastructure. The model is calibrated to fit data for India, an approximately closed economy. Simulations suggest that fiscal policy certainly matters and the choice of the income taxation rate, the mix of government spending between infrastructure and public consumption goods, and the long-run government debt/GDP ratio can all significantly affect the long-run growth rate. Intertemporal aspects of fiscal policy are also important and the precommitment (time-inconsistent) and non-precommitment policies differ substantially. 相似文献

Tramadol (Ultram) is a centrally acting, synthetic analgesic agent. Although it has some affinity for the opiate receptors, tramadol is believed to exert its analgesic effect by inhibiting the re-uptake of norepinephrine and serotonin. There are several published cases of tramadol's involvement in drug-related deaths and impairment. Reports of deaths involving tramadol alone with associated tissue concentrations are rare. This report documents a case in which tramadol overdose was identified as the cause of death. The following tramadol concentrations were found in various tissues: blood, 20 mg/L; urine, 110.2 mg/L; liver, 68.9 mg/kg; and kidney, 37.5 mg/kg. Tissue distributions of the two primary metabolites, N-desmethyl and O-desmethyl tramadol, are also reported. In each tissue or fluid except urine, the tramadol concentration was greater than either metabolite, consistent with other reports of drug-impaired drivers and postmortem cases. The O-desmethyl metabolite concentration was greater than the N-desmethyl metabolite concentration in all tissues; this is in contrast to other postmortem reports, in which the majority of cases report concentrations of O-desmethyl as less than those of N-desmethyl. This may be useful as an indicator of time lapse between ingestion and death. 相似文献

Three basic directions of the economy's perestroyka (social orientation, uskoreniye of technological readjustment, and restructuring of management in enterprises) are outlined by its leading architect and advisor to General Secretary Gorbachev. The presentation, commencing the first joint Soviet Economy round-table, is followed by questions and comments by American participants relating to sequence, momentum, transition, anticipated consequences and contradictions in the reform. A rejoinder covering such issues as priorities, price formation, adaptation to change, allocation of resources and comparison with the Hungarian and other models, is followed by a concluding exchange of views on competition.
