日本经济长期萧条的根本原因--在于"政府为特殊利益集团俘虏"吗?

从日本泡沫经济产生的根源、不良债权难以有效解决的原因、结构性经济改革难以推进的制约因素等方面分析，认为“政府为特殊利益访华团俘虏”是造成日本经济长期萧条的根本原因缺乏坚实的现实依据。仅从金融业的层面思考和解决不良债权问题不会从根本上解决该问题，仅从利益再调整的角度分析结构性改革的难度也没有完全理解改革的复杂性。     

构皮滩水电站烂泥沟砂石系统设计与实践

烂泥沟砂石系统是构皮滩水电站主体工程混凝土骨料加工的主要基地,共需加工混凝土骨料约600万m3,其料源为观景料场玉龙山灰岩,湿抗压强度大于50 MPa。该系统的骨料破碎筛分采用三段破碎四级筛分工艺,人工制砂采用棒磨机与立式冲击破联合制砂工艺。本文结合该系统工艺设计与施工,对系统设计中的关键技术进行了分析与总结。     

关于统筹国内发展和对外开放的几点思考

统筹国内发展和对外开放,是贯彻科学发展观的一个重要方面。要全面把握国际国内的发展趋势,将内外经济政策统一于国家的战略利益。目前国内发展的中心问题,是转变片面的GDP导向思路,确立国家竞争力导向原则。要以我为主,推动产业结构优化升级,提高自主创新能力。要坚持平等互利原则,处理好对外开放、独立自主和经济安全的关系。

有源滤波器非线性行为分析及其电磁干扰的抑制

对具有结构不稳定性的有源滤波器的非线性问题进行了研究，通过对绝缘栅双极型晶体管（IGBT）器件开关过程产生的瞬态电流脉冲的传播过程进行分析，将IGBT器件的控制电压引起的结构稳定问题的抑制转化为该瞬态电流脉冲传播通路的阻断。利用仿真和实验对正激式与反激式开关变换器进行抗干扰能力的研究，说明反激式开关变换器用于有源电力滤波器(APF)的辅助开关电源，更有利于APF对非线性问题的抑制。     

Are Housing Price Cycles Driven by Irrational Expectations?

This paper investigates the extent to which condominium apartment prices are set in an efficient asset market. Unlike previous work that focuses on the time-series properties of measures of excess returns, the analysis is framed in terms of the changes in observable house prices over time. More precisely, the paper develops and applies a test of the joint null hypothesis of rational expectations, perfect markets, and no risk premium in the Vancouver condominium apartment market. The empirical results provide significant evidence against the joint null hypothesis. On average, ex post house price changes move in a direction opposite to their rational expectation. This approach offers a methodological advantage over the standard efficiency literature and is shown to provide a more powerful test of market efficiency than conventional return regressions. Another contribution of the paper is to characterize the time-series properties of deviations of condominium prices from those predicted by the risk-neutral rational expectations model, using cointegration and random coefficients techniques. Deviations in house price changes from their (risk-neutral) rational expectations are time varying, stationary, and related to the stage of the real estate price cycle.     

Political feasibility of structural adjustment in africa: an application of SAM mixed multipliers

The implementation of structural adjustment programs (SAPs) has often been undermined by opposition from politically powerful groups who are favored by existing policies. To assess the political sustainability of SAPs this paper uses social accounting matrices for three African countries to model the income effects of stylized SAPs on different socioeconomic groups. The analysis reveals wide variation in the likelihood for typical SAPs to be acceptable to political elites while generating growth in the rest of the economy. The presence of a rural elite or strong farm-nonfarm linkages can enhance the political sustainability of SAPs.
