国际油气勘探开发项目风险研究——基于变权理论

国际油气勘探开发项目从资源丰度到技术难度、从政治形势到经济效益,都蕴含了诸多的风险,但已有的研究中通常使用常权评价模型,从而降低了项目的总体风险,隐没了突出问题的严重性,从而失去了评价的公正性和有效性。本文结合变权理论,构建了多层次、多目标的变权综合评价模型,计算项目风险的变权综合评价值。其中,通过对评价值上限和下限的引用,对关键风险指标设置了＂门槛＂条件,凸显了关键风险因素对决策的决定意义;而α取值的确定,也反映了决策者的目标取向。最后,本文通过项目案例验证了变权综合评价方法在国际油气合作项目风险评价中应用的有效性。     

中国利率政策与房地产价格的互动关系研究

本文通过建立结构向量自回归模型对中国房地产价格与利率政策之间的互动关系进行了探讨,发现中国的利率政策并不能对房地产价格形成有效的调节,造成了利率政策房地产价格传导渠道的失效;相反,房地产价格冲击对利率政策却具有显著的正向影响,说明中国历史上的利率政策制定的确参考了房地产价格因素,并对其作出了一定的反应。本文还利用模拟分析对样本期间内我国利率政策的实施效果进行了分析评价。研究结论对中国中央银行利率政策的有效执行及房地产市场调控具有重要政策启示。     

国际原油价格波动对中国宏观经济影响的重新考察

本文对国际原油价格波动对中国宏观经济的影响进行了重新考察。研究发现:国际原油价格通过影响采购经理人指数进而影响中国主要宏观经济变量,采购经理人指数的引入,完善了国际原油价格波动对中国宏观经济影响的时序传导机制,从而提高了实证结果的显著性。实证结果显示:国际原油价格上涨对中国消费者价格指数有正向影响,但这一结果并不显著;同时国际原油价格上涨并未改变中国经济增长的总体态势。VEC实证模型的估计结果表明:国际原油价格与中国宏观经济变量之间存在显著的协整关系,而且国际原油价格波动对中国宏观经济的影响存在滞后效应。     

Inflation persistence and exchange rate regime: Implications for dynamic adjustment to shocks in a small open economy

The paper examines implications of inflation persistence for business cycle dynamics following terms of trade shock in a small oil producing economy, under inflation targeting and exchange rate targeting regimes. It is shown that due to the ‘Walters critique’ effect, the country’s adjustment paths are slow and cyclical if there is a significant backward-looking element in the inflation dynamics and the exchange rate is fixed. It is also shown that such cyclical adjustment paths are moderated if there is a high proportion of forward-looking price setters in the economy, so that when the Phillips curve becomes completely forward-looking cyclicality in adjustment paths disappears and the response of the real exchange rate becomes hump-shaped. In contrast, with an independent monetary policy, irrespective of the degree of inflation persistence, flexible exchange rate allows to escape severe cycles, which results in a smooth response of the real exchange rate.     

期权加油卡的产品设计、定价和套期保值研究

在消费者被迫接受成品油价格风险、石油零售商零售业竞争日益激烈和我国成品油定价机制矛盾日益突出的背景下,本文提出石油零售商可发行期权加油卡来实现下面三个目标:(1)为消费者提供成品油价格风险管理的工具;(2)为石油零售商提供一种新的锁定客户的营销手段;(3)推进成品油的市场化改革。本文首先设计期权加油卡,然后采用蒙特卡罗模拟方法对加油卡定价,接着分析石油零售商发行加油卡的风险的套期保值损益,最后讨论期权加油卡的相关实际操作问题。     

以期货市场为突破口推进大连区域性金融中心建设

从地区发展构想以及区域经济发展的角度,中国内地许多中心城市都提出了建设区域性金融中心的设想,进而涌现出了建设区域性金融中心的热潮。环渤海地区的大连、天津、沈阳等城市都确定了建设金融中心的发展战略。三个城市各自拥有自己的优势与不足,应扬长避短,错位发展。大连应充分利用大连商品交易所这一独特的金融资源,以期货业为龙头,带动相关机构和市场资源的聚集。     

Measuring the cost of liquidity in agricultural futures markets: Conventional and Bayesian approaches

Estimating the cost of liquidity in agricultural futures markets is challenging because bid‐ask spreads are usually not observed. Based on an ability to reflect simulated data from Roll's spread model, we assess the effectiveness of conventional and Bayesian bid‐ask spread estimators under different market conditions. Conventional serial covariance and absolute price change spread estimators appear to be biased. Hasbrouck's Bayesian estimator generates small costs of liquidity whose values depend on the correlation and noise in the data. The absolute value Bayesian estimator is precise and works well under conditions of high levels of noise and correlation usually found in agricultural futures markets. Using data from live cattle (LC) and lean hog (LH) contracts, we find similar patterns of performance that produce economically meaningful cost of liquidity differences.     

A regression discontinuity approach to measuring the effectiveness of oil and natural gas regulation to address the common-pool externality

Oil and natural gas reservoirs typically span multiple productive leases so that no owner has rights to the entire stock of resource, resulting in production externalities. Previous literature has examined the effectiveness of government regulation in Texas and Oklahoma in abating these externalities, finding Oklahoma to be more successful in unifying common pools and securing property rights. Using regression discontinuity design, we quantify the impact of regulatory difference between the two states. We find that Oklahoma produces an average of 3361 more barrels of oil over the life of a well, relative to Texas. Given the maturity of the fields in question, the result underscores the continuing importance of addressing common pool externalities even after the primary phase of recovery has largely been completed.     

Leverage vs. feedback: Which Effect drives the oil market?

This article brings new insights on the role played by (implied) volatility on the WTI crude oil price. An increase in the volatility subsequent to an increase in the oil price (i.e. inverse leverage effect) remains the dominant effect as it might reflect the fear of oil consumers to face rising oil prices. However, this effect is amplified by an increase in the oil price subsequent to an increase in the volatility (i.e. inverse feedback effect) with a two-day delayed effect. This lead-lag relation between the oil price and its volatility is central to any type of trading strategy based on futures and options on the OVX implied volatility index. It is of interest to traders, risk- and fund-managers.     

Better cross hedges with composite hedging? Hedging equity portfolios using financial and commodity futures

Unless a direct hedge is available, cross hedging must be used. In such circumstances portfolio theory implies that a composite hedge (the use of two or more hedging instruments to hedge a single spot position) will be beneficial. The study and use of composite hedging has been neglected; possibly because it requires the estimation of two or more hedge ratios. This paper demonstrates a statistically significant increase in out-of-sample effectiveness from the composite hedging of the Amex Oil Index using S&P500 and New York Mercantile Exchange crude oil futures. This conclusion is robust to the technique used to estimate the hedge ratios, and to allowance for transactions costs, dividends and the maturity of the futures contracts.
