International Business Cycle Asymmetry and Time Irreversible Nonlinearities

Using tests of time reversibility, this paper provides further statistical evidence on the long-standing conjecture in economics concerning the potentially asymmetric behaviour of output over the expansionary and contractionary phases of the business cycle. A particular advantage of this approach is that it provides a discriminating test that is instructive as to whether any asymmetries detected are due to asymmetric shocks to a linear model, or an underlying non-linear model with symmetric shocks, and in the latter case is informative as to the potential form of that nonlinear model. Using a long span of international per capita output growth data, the asymmetry detected is overwhelmingly consistent with the long standing perception that the output business cycle is characterized by steeper recessions and longer more gentle expansions, but the evidence for this form of business cycle asymmetry is weaker in the data adjusted for the influence of outliers associated with wars and other extreme events. Statistically significant time irreversibility is reported for the output growth rates of almost all of the countries considered in the full sample data, and there is evidence that this time irreversibility is of a form implying an underlying nonlinear model with symmetrically distributed innovations for 15 of the 22 countries considered. However, the time irreversibility test results for the outlier-trimmed full sample data reveal significant time irreversibility in output growth for around one half of the countries considered, predominantly in Northern Europe and North America, and of a form implying a nonlinear underlying model in only a further half of those cases.

我国企业管理信息系统的发展——计算机辅助企业管理分析

管理信息系统(Management Information Systems—MIS)是一种现代化企业管理的方法或手段,它已经在经济发达的国家里被广泛采用.我国的MIS开发应用虽然起步晚了一些,但经过近十几年来的发展。在总量上也具有一定的规模.有成功的经验。也有失败的教训.其原因众说纷纭。但很少有较系统地加以总结的.本文将在国内外、特别是国内现有的关于这方面研究的基础上,作一些较为全面综合的分析,并在此基础上对我国企业今后的MIS开发应用提出若干建议.     

室内杀虫剂煤油溶剂的脱色脱硫醇研究

用改性蒙脱石预先对煤油脱色，再以活性炭为载体，氯化稀土混合物为催化剂，加入适当的助催化剂、活化剂，在弱碱性介质中，以空气氧为氧化剂，对工业煤油进行脱硫醇．硫醇的脱除率为１００％；色度小于１号；抗腐蚀实验为１级，无水溶性酸碱，酸值（ＫＯＨ）为０．０２ｍｇ／１００ｍＬ．处理后的煤油可作室内杀虫剂的超级溶剂．
