关键词： HYSTERESIS (Economics)   SCOTLAND -- Economic conditions  

摘要： This paper explores the properties of an open economy model in which real exchange rate overshooting has a permanent impact on the rate of unemployment via a hysteresis mechanism. The magnitude of this effect depends on the slope of the short-run Phillips curve, the speed with which expectations adjust in the labour market, and on the speed with which capacity adjusts to changes in capacity utilisation. However, it does not depend on here open the economy is, although the dynamics of the adjustment process (including the extent of the initial jump in the exchange rate following a change in monetary policy) do depend on this factor.

关键词： macroeconomic model   recycling   waste management   environmental industry  

摘要： The objective of this research is to evaluate optimal solutions taking into consideration not only conventional economic activities, but also activities for environmental preservation such as waste management and environmental investment. In order to investigate these activities, we constructed and performed simulations with a multi-sectoral dynamic macroeconomic model, which includes waste generation from each sector as well as the waste reduction, recycling, and final disposal processes. Although recycling activities are more costly than other waste management processes such as incineration and direct final disposal, there are some economic benefits in terms of recovery of economic goods. Our simulations revealed that in cases where there will not be a severe shortage of space for final disposal in the future, the incinerator process can be expected to be adopted for the reduction of waste for final disposal. On the other hand, in cases where severe space constraints exist, the recycling process will become the method of choice because waste management costs will become rise exponentially and the economic recovery benefit of recycling activities will be recognized as being much more important. Simulations performed with a version of the model that separates industries supplying equipment for environmental control from other conventional manufacturing sectors demonstrated that environmental industries have a large potential for both environmental improvement and economic progress.

关键词： 宏观经济   股票市场   股份制经济模型   周期波动   ASMEC-S模型   利率   宏观调控  

摘要： 为了分析宏观经济与股票市场之间的相互影响，我们提供了一个基于主体的股份制经济模型－－ASMEC－S。人工经济由多个家庭、多个消费品企业、一个资本品企业、一个银行和一个政府组成。消费品企业是股份制企业，政府和众多家庭是它们的股东。家庭的消费剩余可以用于股票市场的投资，是否买卖某种股票取决于家庭的预期。消费品企业通过调整劳动力数目和资本数目控制生产规模，并应用分类器系统完善定价策略。政府可以通过调整劳动力数目和资本数目控制生产规模，并应用分类器系统完善定价策略。政府可以通过制定货币政策调控经济运行。实验结果表明：宏观经济和股票市场均呈现出周期波动；政府适当地调整利率能够使宏观经济和股票市场运行比较平稳。

关键词： endogenous fluctuations   periodic cycles   Hopf bifurcation   sunspot equilibrium  

摘要： This paper constructs a simple intertemporal model of a small open economy inhabited by forward looking agents, in which endogenous fluctuations in the real exchange rate can arise in equilibrium, i.e. fluctuations that are not linked to movements in economic fundamentals. The key condition for the main results is the assumption that the Marshall-Lerner condition does not hold (i.e. that the country's exports and imports are inelastic to its real exchange rate). It is shown that, given that the Marshall-Lerner condition fails, there exist periodic equilibria and/or stationary sunspot equilibria in the neighborhood of the stationary state.
