Summary In overlapping-generations models of fiat money, the existence of a Pareto-optimal equilibrium — which defines an optimal quantity of money — is more general than well-known counter-examples suggest. Those examples, having no optimal equilibrium just because there are small variations in households' tastes and endowments across generations, are not typical. On the contrary: For an open-dense, full-measure subset of smooth stationary economies and an open-dense subset of continuous stationary economies, introducing small variations in tastes and endowments across generations preserves the existence of an optimal equilibrium. Put simply, optimal equilibria generically exist for nearly-stationary economies.I thank Scott Freeman, Katsuhiko Kawai, and two referees for proofreading this text; all lead to clarifications. 相似文献

股票市场收益率波动长记忆性的分解及实证研究 总被引:1,自引:0,他引:1
目前股票市场长记忆性检验和建模方法,不能很好地消除短期记忆的影响,针对这一问题,本文提出寻找序列的突变点,通过将序列分解为只包含长记忆性部分和不包含长记忆性部分的序列分解技术,来排除短期记忆的影响。对上证指数和深圳成分指数收益率波动的长记忆性进行实证研究发现,将序列分解以后进行长记忆性检验,不仅可以得出长记忆性检验更为精确的结论,同时可以检验序列分解过程的效果。 相似文献

This paper employs duration analysis to investigate the timing of default in the UK mortgage market. Our analysis is performed on an ex ante basis, in that our explanatory variables are available to mortgage lenders when the loan is first made. We estimate both standard Weibull distributions and generalizations of the Weibull that permit non-monotonic hazard functions. The models fit the data well, suggesting that we have captured the major sources of variation in duration. We find that ‘cash flow’ variables, such as salary and interest rate paid, play the largest role. Surprisingly, loan-to-value ratios are either insignificant or influence default times in a counter-intuitive direction. 相似文献

The New York State Environmental Externalities Cost Study and computerized externality model (EXMOD) are used to examine the specification of methods design and application factors in the computation of electricity externalities. We report the sensitivity of externality estimates with alternative specifications for 15 different factors in the analysis, including the selection of facility type, site, and operating characteristics; air emission assumptions and air modeling procedures; dose-response assumptions; economic valuation assumptions; and other modeling procedures and assumptions. Many of the factors that most influence externality computations can be well specified in the analysis, such as the facility type, age, characteristics, emission rates, whether there is SO2 trading, and the inclusion of long range impacts. Most significant among the factors for which there remains significant scientific uncertainty are the selection and application of air dispersion models, selection of air pollution thresholds for health impacts, reduced life span risks associated with ozone exposure and with long-term exposure to PM10, values for CO2 damages, and the value to be applied to increased risks of reduced life span for individuals age 65 or older. 相似文献

Abstract. This paper is concerned with the relationship between education, wages and working behaviour. The work is partly motivated by the sharp distinction in the literature between the returns to education and the effect of wages on labour supply. Education is the investment that cumulates in the form of human capital while labour supply is the utilization rate of that stock. Yet, variation in education is usually the basis for identifying labour supply models – education is assumed to determine wages but not affect labour supply. Moreover, it is commonly assumed that the private rate of return to education can be found from the schooling coefficient in a log-wage equation. Yet, the costs of education are largely independent of its subsequent utilization but the benefits will be higher the greater the utilization rate. Thus the returns will depend on how intensively that capital is utilized and we would expect that those who intend to work least to also invest least in human capital. Indeed, the net (of tax liabilities and welfare entitlements) return to education will be a complex function of labour supply and budget constraint considerations.
Here we attempt to model the relationship between wages, work, education and the tax/welfare system allowing for the endogeneity of education as well for the correlations between the unobservable components of wages and working behaviour. We use the estimates to simulate the effect of a new UK policy designed to increase education for children from low-income households. 相似文献

The main goal of this paper is to study the effects of fiscal policy on the current account in the Italian economy through the analysis of one of the most innovative intertemporal models of recent years, the Obstfeld–Rogoff Redux model. The author proposes an innovative econometric approach to the model, based on the estimation of the microeconomic parameters that appear in its fundamental equations. The estimated parameters are used to empirically determine the multipliers that, according to the theory, connect permanent and temporary variations in public expenditure to the current account. Estimation is carried out on a dynamic extension of the original model, which has been developed modifying the first order conditions system of the maximization problem. Finally, the author provides a comparison between the results obtained and the actual dynamics of the Italian current account balance. 相似文献

We distinguish learning in a static environment from that in a dynamic environment to show the existence of an important interaction between the development of new technologies and human capital accumulation. Because technological progress creates a more dynamic environment, it complements education in the production of human capital by enhancing adaptive skills. Higher levels of adaptability and human capital in turn determine the profitability of new inventions and the incentive to invest in new R&D. Differences in the history of technological progress produce different levels of adaptability and our results suggest why countries that have comparable levels of education and per capita incomes may differ significantly in their growth performance. 相似文献

The European Commission issued a proposal for reform of some aspects of Communitary competition policy. In particular, proposes a shift from ex-ante control (notification system) to an ex-post control regime of agreements (or decisions) conflicting with Article 81 (Ex-Article 85).We highlight the expected effects of this shift on the type of agreements that firms will implement. The type of agreements has been taken as exogenous in most analysis of the reform proposal. We contend that significant economic effects may result from recognizing the endogeneity of agreements.We predict that the proposed reform will result, in general, in firms implementing less restrictive agreements. 相似文献
