市场供需量受价格波动影响之研究

本文研究了价格函数随时间变化引起供给量和需求量的变化规律。主要针对不同情况分别讨论了价格波动的蛛网模型、微分动力学模型及差分方程模型。对各模型进行了定量求解,并进一步具体讨论了这三种模型的价格波动周期解及稳定性的条件。     

扩大内需的着力点——提高劳动力价格

扩张性财政政策和宽松的货币政策一度成为解决“内需”问题的良药。但实践证明,这种治标不治本的凯恩斯主义的药方最终会导致通货膨胀,不能根治经济中内需不足的问题。文章通过对国民收入分配中劳动者所处地位的分析,得出我国内需不足的问题来自于收入分配的问题。因此,扩大内需的着力点在于提高劳动力价格。     

浅析天然气管道运输定价

天然气管道运输定价对于天然气市场的发展有着重要的作用,我国传统的天然气定价机制不能够适应天然气管输的特性,与我国天然气市场的需求已不相适应,本文将我国现阶段的一部制天然气定价方法与国外成熟的两部制天然气定价方法相比较,为我国的天然气管输定价机制的改革提出了合理性建议。     

我国景区门票价格上涨的调控对策

我国景区门票价格的轮番上涨引发了社会各界人士的紧密关注,各类涨价理由招致了大众的质疑。文章通过各类数据分析,阐述了我国景区门票价格现存问题、分析了我国景区价格上涨的内在原因。最后从经营目标、资金渠道、景区管理、资源保护、听证制度五个方面提出了调控价格上涨建议。     

物价稳定、货币流通速度与宏观调控愿景把握

对欧美国家和我国曾经发生的货币流通速度陡升型通胀和货币流通速度陡降型通缩进行实证分析表明,现阶段我国货币流通速度似处于一个非渐变、非常规的特殊时期,相关不确定性因素一旦演变为确定性的组合,很可能产生经济运行中的某种临界转换点,并可能对我国货币政策和宏观政策调控带来挑战。应加强对货币流通速度的监测和对货币需求变化的研究预测,进而优化市场预期管理和宏观应急管理,提高应对货币流通速度突变型通胀、通缩的能力,以更好地追求与维护物价稳定和提高宏观调控水平。     

价格洼地、非市场化供给与收入分配效应——基于长沙楼市的研究

近年来全国房价快速上涨,各地房价出现你追我赶现象。但过去几年,长沙房地产市场却较为平稳,房价水平和上涨幅度与其他同等城市相比,均处于低位,呈现出明显的价格洼地特征。价格洼地的形成与长沙大量土地及住房的非市场化供给有很大关系,并在不同市场主体间产生了财富转移及收入分配效应。     

Oil price shocks and American depositary receipt stock returns

In this paper we examine the impact of oil price shocks on twelve countries American Depositary Receipt (ADR) returns using monthly data from 1999.01 to 2014.12. The results show that oil price shocks have a positive and statistically significant impact on ADR return in all twelve countries. These results are robust to the inclusion of other explanatory variables such as oil price volatility and the spillover of the United States stock market. Further analysis shows that this effect is stronger in the post financial crisis time period compared to the pre-financial crisis time period.     

Does easing monetary policy increase financial instability?

This paper develops a model featuring both a macroeconomic and a financial friction that speaks to the interaction between monetary and macro-prudential policy and to the role of US monetary and regulatory policy in the run up to the Subprime mortgage crisis. There are two main results. First, interest rate rigidities in a monopolistic banking system increase the probability of a financial crisis (relative to the case of flexible interest rate) in response to contractionary shocks to the economy, while they act as automatic macro-prudential stabilizers in response to expansionary shocks. Second, when the interest rate is the only available instrument, monetary policy faces a trade-off between macroeconomic and financial stability. This trade off is both qualitative and quantitative in response to contractionary shocks, while it is only quantitative in response to positive shocks. We show that a second instrument, such as a Pigouvian tax on credit to households on the demand side of the market, is needed to restore efficiency in the economy when both frictions are at work.     

Quote inefficiency in options markets

In an arbitrage-free economy with non-zero bid-ask spreads the existence of payoffs whose price is lower than the price of a dominated payoff cannot be discarded in general. However, when the former price corresponds to trivial portfolios which involve buying or selling one unit of the basis assets, its presence, although not an arbitrage, is a severe market anomaly which we refer to as an inefficient quote. In an empirical study, we report evidence that indicates that in options markets both the frequency and the magnitude of these anomalies are substantial and we document puzzling patterns in their behavior.     

我国化肥价格波动与农民收入关系的实证分析

本文利用1978～2008年的时间序列数据,运用脉冲响应函数和方差分解技术考察化肥价格波动与农民收入之间的关系,发现化肥价格的波动与农民收入变化之间存在着双向的因果关系,即化肥价格的上涨导致农民增收缓慢,而化肥价格上涨的根本原因在于＂需求拉动＂和＂成本推动＂。今后必须从需求和供给两方面采取对策：一方面通过建立化肥直接补贴制度和化肥储备制度,从需求上控制化肥价格上涨;另一方面通过采用新型化肥生产技术和给予化肥生产企业生产用能以优惠政策,从供给上控制化肥价格上涨。
