This paper proposes a technique for computing optimal taxes in a full general equilibrium model. It is based upon a fixed point algorithm of the type that is widely used to solve Walrasian general equilibrium models. Computing an optimal tax equilibrium is more difficult than solving a general equilibrium model only to the extent that the derivatives of the social welfare function and of the consumer demand functions must be calculated in the former case. Solutions to several sample problems are provided to demonstrate the technique. They suggest that optimal tax rates are exceedingly sensitive to the specification of the model used to derive them. 相似文献

Resource allocation in the energy sector of the United Kingdom is a difficult area to plan, because demand and supply projections need to embrace both the large private sector oil industry and the public sector fuel industries. In addition, relationships between the latter are complex as they involve both competition and co-ordination. One approach to the problem has been to find common ground in the concept of marginal cost pricing, but there are practical difficulties in application. Government has encouraged the use of analytical techniques, such as corporate planning, by the fuel industries as a means of co-ordination in areas where market mechanisms may no longer always be effective. 相似文献

We examine associations between accounting measures of earnings and stock returns in Japan over varying window lengths and compare them to those for the United States. Our results are consistent with the view that Japanese investors utilize less accounting information in their pricing of equities than do their U.S. counterparts. This was particularly evident in the 'boom' period of the mid to late 1980s when the fundamental values conveyed by accounting measures appear to have been largely ignored. The association increases with the inclusion of 1991, suggesting a return to more emphasis on fundamentals with the recent decline in stock prices. 相似文献

Price Stability and the Case for Flexible Exchange Rates 总被引:1,自引:1,他引:0
We revisit Friedman’s case for flexible exchange rates in a small open economy with several distortions and rigidities and
a variety of domestic and external shocks. We find that, for external shocks, the flexible exchange rate regime outperforms
the fixed regime independent of the source of domestic nominal rigidities provided that the monetary authorities pursue a
policy of strict inflation targeting. For domestic supply shocks, a joint policy of a flexible exchange rate and strict inflation
targeting fares well when the main source of nominal rigidities is in the domestic goods markets, but not if rigidities arise
in the labor markets. 相似文献

Aims: To examine healthcare resource utilization associated with refractory myasthenia gravis (MG) in England.Materials and methods: This was a retrospective cohort study of linked data from the Clinical Practice Research Datalink and the Hospital Episode Statistics database collected between 1997 and 2016. Included patients were ≥18?years of age at the index MG diagnosis. Patients with refractory MG were identified using an algorithm based on treatments received. Healthcare resource utilization since the index date was compared between refractory and non-refractory cohorts.Results: The study included 1149 patients with MG, of whom 66 (5.7%) were refractory. Sex and age at diagnosis did not significantly differ between the refractory and non-refractory cohorts. Rates of healthcare resource utilization per person-year were significantly higher (p?.05) for patients with refractory compared to non-refractory MG for GP visits, visits to other healthcare professionals, outpatient visits and inpatient hospitalization. Patients in the refractory cohort spent more total days hospitalized since the index visit than patients in the non-refractory cohort (median, 33 vs. 16?days [p?.0001]).Limitations: The algorithm for identifying refractory patients did not include clinical criteria. Also, treatments administered in hospitals or by specialists were not available in the databases.Conclusions: Patients in England with refractory MG more often visit healthcare providers, are hospitalized and visit an emergency room than patients with non-refractory MG. 相似文献

This article examines the relationship between individuals' weight and employment decisions over the life cycle. I estimate a dynamic stochastic model of individuals' annual choices of occupation, hours worked, and schooling. Evidence suggests that heavier individuals face higher switching costs when transitioning into white‐collar occupations, earn lower returns to experience in white‐collar occupations, and earn lower wages in socially intensive jobs. I simulate a hypothetical antidiscrimination policy treating obese workers as a protected class. Although such a policy would reduce gaps in occupational attainment, it would have little effect on the observed divergence in wages between obese and nonobese workers. 相似文献
